`nb` is a command line and local web note‑taking, bookmarking, archiving, and knowledge base application with: - plain text data storage, - [encryption](#password-protected-encrypted-notes-and-bookmarks), - [filtering](#listing--filtering), [pinning](#-pinning), [#tagging](#-tagging), and [search](#-search), - [Git](https://git-scm.com/)-backed [versioning](#-revision-history) and [syncing](#-git-sync), - [Pandoc](https://pandoc.org/)-backed [conversion](#%EF%B8%8F-import--export), - [[wiki-style linking]], - terminal and GUI web [browsing](#-browsing), - inline [images](#-images), - [todos](#-todos) with [tasks](#%EF%B8%8F-tasks), - global and local [notebooks](#-notebooks), - organization with [folders](#-folders), - customizable [color themes](#-color-themes), - extensibility through [plugins](#-plugins), and more, in a single portable script. `nb` creates notes in text-based formats like [Markdown](https://en.wikipedia.org/wiki/Markdown), [Org](https://orgmode.org/), [LaTeX](https://www.latex-project.org/), and [AsciiDoc](https://asciidoc.org/), can work with files in any format, can import and export notes to many document formats, and can create private, password-protected encrypted notes and bookmarks. With `nb`, you can write notes using Vim, Emacs, VS Code, Sublime Text, and any other text editor you like, as well as terminal and GUI web browsers. `nb` works in any standard Linux / Unix environment, including macOS and Windows via WSL, MSYS, and Cygwin. [Optional dependencies](#optional) can be installed to enhance functionality, but `nb` works great without them.

`nb` is also a powerful [bookmarking](#-bookmarks) system featuring: - locally-served, text-centric, distraction-free bookmark [browsing](#-browsing) in terminal and GUI web browsers, - local full-text search of cached page content with regular expression support, - convenient filtering and listing, - [Internet Archive Wayback Machine](https://archive.org/web/) snapshot lookup for broken links, - tagging, pinning, linking, and full integration with other `nb` features. Page information is downloaded, cleaned up, structured, and saved into normal Markdown documents made for humans, so bookmarks are easy to view and edit just like any other note.

`nb` uses [Git](https://git-scm.com/) in the background to automatically record changes and sync notebooks with remote repositories. `nb` can also be configured to sync notebooks using a general purpose syncing utility like Dropbox so notes can be edited in other apps on any device.

`nb` is designed to be portable, future-focused, and vendor independent, providing a full-featured and intuitive experience within a highly composable multimodal user-centric text interface. The entire program is contained within a single [well-tested](#tests) shell script that can be installed, copied, or `curl`ed almost anywhere and just work, using a strategy inspired by [progressive enhancement](https://en.wikipedia.org/wiki/Progressive_enhancement) for various experience improvements in more capable environments. `nb` works great whether you have one notebook with just a few notes or dozens of notebooks containing thousands of notes, bookmarks, and other items. `nb` makes it easy to incorporate other tools, writing apps, and workflows. `nb` can be used a little, a lot, once in a while, or for just a subset of features. `nb` is flexible.

### Installation #### Dependencies ##### Required - [Bash](https://en.wikipedia.org/wiki/Bash_(Unix_shell)) - `nb` works perfectly with Zsh, fish, and any other shell set as your primary login shell, the system just needs to have Bash available on it. - [Git](https://git-scm.com/) - A text editor with command line support, such as: - [Vim](https://en.wikipedia.org/wiki/Vim_$text_editor$), - [Emacs](https://en.wikipedia.org/wiki/Emacs), - [Visual Studio Code](https://code.visualstudio.com/), - [Sublime Text](https://www.sublimetext.com/), - [Helix](https://helix-editor.com/), - [micro](https://github.com/zyedidia/micro), - [nano](https://en.wikipedia.org/wiki/GNU_nano), - [Atom](https://atom.io/), - [TextMate](https://macromates.com/), - [MacDown](https://macdown.uranusjr.com/), - [some of these](https://github.com/topics/text-editor), - [and many of these.](https://en.wikipedia.org/wiki/List_of_text_editors) ##### Optional `nb` leverages standard command line tools and works in standard Linux / Unix environments. `nb` also checks the environment for some additional optional tools and uses them to enhance the experience whenever they are available. Recommended: - [`bat`](https://github.com/sharkdp/bat) - [`ncat`](https://nmap.org/ncat/) or [`socat`](https://www.kali.org/tools/socat/) - [`pandoc`](https://pandoc.org/) - [`rg`](https://github.com/BurntSushi/ripgrep) - [`tig`](https://github.com/jonas/tig) - [`w3m`](https://en.wikipedia.org/wiki/W3m) Also supported for various enhancements: [Ack](https://beyondgrep.com/), [`afplay`](https://ss64.com/osx/afplay.html), [`asciidoctor`](https://asciidoctor.org/), [The Silver Searcher (`ag`)](https://github.com/ggreer/the_silver_searcher), [`catimg`](https://github.com/posva/catimg), [Chafa](https://github.com/hpjansson/chafa), [Chromium](https://www.chromium.org) / [Chrome](https://www.google.com/chrome/), [`eza`](https://github.com/eza-community/eza), [`ffplay`](https://ffmpeg.org/ffplay.html), [ImageMagick](https://imagemagick.org/), [`glow`](https://github.com/charmbracelet/glow), [GnuPG](https://en.wikipedia.org/wiki/GNU_Privacy_Guard), [`highlight`](http://www.andre-simon.de/doku/highlight/en/highlight.php), [`imgcat`](https://www.iterm2.com/documentation-images.html), [`joshuto`](https://github.com/kamiyaa/joshuto), [kitty's `icat` kitten](https://sw.kovidgoyal.net/kitty/kittens/icat.html), [`lsd`](https://github.com/lsd-rs/lsd), [Links](https://en.wikipedia.org/wiki/Links_(web_browser)), [Lynx](https://en.wikipedia.org/wiki/Lynx_(web_browser)), [`mdcat`](https://github.com/swsnr/mdcat), [`mdless`](https://github.com/ttscoff/mdless), [`mdv`](https://github.com/axiros/terminal_markdown_viewer), [Midnight Commander (`mc`)](https://en.wikipedia.org/wiki/Midnight_Commander), [`mpg123`](https://en.wikipedia.org/wiki/Mpg123), [MPlayer](https://en.wikipedia.org/wiki/MPlayer), [`ncat`](https://nmap.org/ncat/), [`netcat`](https://netcat.sourceforge.net/), [note-link-janitor](https://github.com/andymatuschak/note-link-janitor) (via [plugin](https://github.com/xwmx/nb/blob/master/plugins/backlink.nb-plugin)), [`pdftotext`](https://en.wikipedia.org/wiki/Pdftotext), [Pygments](https://pygments.org/), [Ranger](https://ranger.github.io/), [readability-cli](https://gitlab.com/gardenappl/readability-cli), [`rga` / ripgrep-all](https://github.com/phiresky/ripgrep-all), [`sc-im`](https://github.com/andmarti1424/sc-im), [`socat`](https://www.kali.org/tools/socat/), [`termvisage`](https://github.com/AnonymouX47/termvisage), [`termpdf.py`](https://github.com/dsanson/termpdf.py), [Tidy-Viewer (`tv`)](https://github.com/alexhallam/tv), [`timg`](https://github.com/hzeller/timg), [vifm](https://vifm.info/), [`viu`](https://github.com/atanunq/viu), [VisiData](https://www.visidata.org/) #### macOS / Homebrew ```bash brew install xwmx/taps/nb ``` Installing `nb` with Homebrew also installs the recommended dependencies above and completion scripts for Bash, Zsh, and Fish. Install the latest development version from the repository with: ```bash brew install xwmx/taps/nb --head ``` `nb` is also available in [homebrew-core](https://github.com/Homebrew/homebrew-core). Installing it together with the `bash` formula is recommended: ```bash brew install nb bash ``` #### Ubuntu, Windows, and others ##### npm ```bash npm install -g nb.sh ``` After `npm` installation completes, run `sudo "$(which nb)" completions install` to install Bash and Zsh completion scripts (recommended). On Ubuntu and WSL, you can run [`sudo "$(which nb)" env install`](#env) to install the optional dependencies. When `nb` is installed on Windows, `socat` ([MSYS](https://packages.msys2.org/package/socat), [Cygwin](https://cygwin.com/packages/summary/socat.html)) is recommended. *`nb` is also available under its original package name, [notes.sh](https://www.npmjs.com/package/notes.sh), which comes with an extra `notes` executable wrapping `nb`.* ##### Download and Install To install as an administrator, copy and paste one of the following multi-line commands: ```bash # install using wget sudo wget https://raw.github.com/xwmx/nb/master/nb -O /usr/local/bin/nb && sudo chmod +x /usr/local/bin/nb && sudo nb completions install # install using curl sudo curl -L https://raw.github.com/xwmx/nb/master/nb -o /usr/local/bin/nb && sudo chmod +x /usr/local/bin/nb && sudo nb completions install ``` On Ubuntu and WSL, you can run [`sudo nb env install`](#env) to install the optional dependencies. ###### User-only Installation To install with just user permissions, simply add the `nb` script to your `$PATH`. If you already have a `~/bin` directory, for example, you can use one of the following commands: ```bash # download with wget wget https://raw.github.com/xwmx/nb/master/nb -O ~/bin/nb && chmod +x ~/bin/nb # download with curl curl -L https://raw.github.com/xwmx/nb/master/nb -o ~/bin/nb && chmod +x ~/bin/nb ``` Installing with just user permissions doesn't include the optional dependencies or completions, but `nb` core functionality works without them. If you have `sudo` access and want to install the completion scripts and dependencies, run the following command: ```bash sudo nb env install ``` ##### Make To install with [Make](https://en.wikipedia.org/wiki/Make_(software)), clone this repository, navigate to the clone's root directory, and run: ```bash sudo make install ``` This will also install the completion scripts on all systems and the recommended dependencies on Ubuntu and WSL. ##### bpkg To install with [bpkg](https://github.com/bpkg/bpkg): ```bash bpkg install xwmx/nb ``` ##### basher To install with [basher](https://www.basher.it/): ```bash basher install xwmx/nb ``` #### Tab Completion Bash, Fish, and Zsh tab completion should be enabled when `nb` is installed using the methods above, assuming you have the appropriate system permissions or installed with `sudo`. If completion isn't working after installing `nb`, see the [completion installation instructions](https://github.com/xwmx/nb/tree/master/etc). #### Updating When `nb` is installed using a package manager like npm or Homebrew, use the package manager's upgrade functionality to update `nb` to the latest version. When installed via other methods, `nb` can be updated to the latest version using the [`nb update`](#update) subcommand. ## Overview

To get started, simply run: ```bash nb ``` `nb` sets up your initial `home` notebook the first time it runs. By default, notebooks and notes are global (at `~/.nb`), so they are always available to `nb` regardless of the current working directory. `nb` also supports [local notebooks](#global-and-local-notebooks). ### 📝 Notes #### Adding

^{↑ ·
nb add,
nb browse add}

Use [`nb add`](#add) (shortcuts: [`nb a`](#add), [`nb +`](#add)) to create new notes: ```bash # create a new note in your text editor nb add # create a new note with the filename "example.md" nb add example.md # create a new note containing "This is a note." nb add "This is a note." # create a new note with piped content echo "Note content." | nb add # create a new password-protected, encrypted note titled "Secret Document" nb add --title "Secret Document" --encrypt # create a new note in the notebook named "example" nb example:add "This is a note." # create a new note in the folder named "sample" nb add sample/ ``` [`nb add`](#add) with no arguments or input will open the new, blank note in your environment's preferred text editor. You can change your editor using the `$EDITOR` environment variable or [`nb set editor`](#editor). `nb` files are [Markdown](https://daringfireball.net/projects/markdown/) files by default. The default file type can be changed to whatever you like using [`nb set default_extension`](#default_extension). [`nb add`](#add) has intelligent argument parsing and behaves differently depending on the types of arguments it receives. When a filename with extension is specified, a new note with that filename is opened in the editor: ```bash nb add example.md ``` When a string is specified, a new note is immediately created with that string as the content and without opening the editor: ```bash ❯ nb add "This is a note." Added: [1] 20200101000000.md ``` [`nb add `](#add) is useful for quickly jotting down notes directly via the command line. Quoting content is optional, but recommended. When no filename is specified, [`nb add`](#add) uses the current datetime as the filename. [`nb add`](#add) can also receive piped content, which behaves the same as [`nb add `](#add): ```bash # create a new note containing "Note content." ❯ echo "Note content." | nb add Added: [6] 20200101000100.md # create a new note containing the clipboard contents on macOS ❯ pbpaste | nb add Added: [7] 20200101000200.md # create a new note containing the clipboard contents using xclip ❯ xclip -o | nb add Added: [8] 20200101000300.md ``` Content can be passed with the [`--content `](#add) option, which also creates a new note without opening the editor: ```bash nb add --content "Note content." ``` When content is piped, specified with [`--content `](#add), or passed as a string argument, use the [`--edit`](#add) flag to open the file in the editor before the change is committed. The title, filename, and content can also be specified with long and short options: ```bash ❯ nb add --filename "example.md" -t "Example Title" -c "Example content." Added: [9] example.md "Example Title" ``` The [`-t `](#add) / [`--title <title>`](#add) option also sets the filename to the title, lowercased with spaces and non-filename characters replaced with underscores: ```bash ❯ nb add --title "Example Title" "Example content." Added: [10] example_title.md "Example Title" ``` Tags can be added with the [`--tags <tag1>,<tag2>...`](#add) option, which takes a comma separated list of tags, converts them to [#hashtags](#-tagging), and inserts them between the title and content: ```bash ❯ nb add "Example content." --title "Tagged Example" --tags tag1,tag2 Added: [11] tagged_example.md "Tagged Example" ❯ nb show 11 --print # Tagged Example #tag1 #tag2 Example content. ``` [Search](#-search) for tagged items with [`nb search`](#search) / [`nb q`](#search): ```bash # search for items tagged with "#tag1" nb search --tag tag1 # search for items tagged with "#tag1" AND "#tag2", short options nb q -t tag1 -t tag2 # search for items tagged with "#tag1" OR "#tag2", arguments nb q \#tag1 --or \#tag2 ``` Files can be created with any file type by specifying the extension either in the filename (`example.md`), the extension by itself (`.md`), or via the [`--type <type>`](#add) option (`--type md`): ```bash # open a new Org file in the editor nb add example.org # open a new reStructuredText file in the editor nb add --type rst # open a new JavaScript file in the editor nb add .js ``` Combining a type argument with piped clipboard content provides a very convenient way to save code snippets using a clipboard utility such as `pbpaste`, `xclip`, or [`pb`](https://github.com/xwmx/pb): ```bash # save the clipboard contents as a JavaScript file in the current notebook pb | nb add .js # save the clipboard contents as a Rust file in the "rust" notebook # using the shortcut alias `nb a` pb | nb a rust: .rs # save the clipboard contents as a Haskell file named "example.hs" in the # "snippets" notebook using the shortcut alias `nb +` pb | nb + snippets: example.hs ``` Use [`nb show`](#show) and [`nb browse`](#browse) to view code snippets with automatic syntax highlighting and use [`nb edit`](#edit) to open in your editor. The [`clip` plugin](#clip) can also be used to create notes from clipboard content. Piping, [`--title <title>`](#add), [`--tags <tag-list>`](#add), [`--content <content>`](#add), and content passed in an argument can be combined as needed to create notes with content from multiple input methods and sources using a single command: ```bash ❯ pb | nb add "Argument content." \ --title "Sample Title" \ --tags tag1,tag2 \ --content "Option content." Added: [12] sample_title.md "Sample Title" ❯ nb show 12 --print # Sample Title #tag1 #tag2 Argument content. Option content. Clipboard content. ``` For a full list of options available for [`nb add`](#add), run [`nb help add`](#add). ##### Password-Protected Encrypted Notes and Bookmarks Password-protected notes and [bookmarks](#-bookmarks) are created with the [`-e`](#add) / [`--encrypt`](#add) flag and encrypted with AES-256 using OpenSSL by default. GPG is also supported and can be configured with [`nb set encryption_tool`](#encryption_tool). Each protected note and bookmark is encrypted individually with its own password. When an encrypted item is viewed, edited, or opened, `nb` will simply prompt for the item's password before proceeding. After an item is edited, `nb` automatically re-encrypts it and saves the new version. Encrypted notes can be decrypted using the OpenSSL and GPG command line tools directly, so you aren't dependent on `nb` to decrypt your files. ##### Shortcut Aliases: `nb a`, `nb +` `nb` includes shortcuts for many commands, including [`nb a`](#add) and [`nb +`](#add) for [`nb add`](#add): ```bash # create a new note in your text editor nb a # create a new note with the filename "example.md" nb a example.md # create a new note containing "This is a note." nb + "This is a note." # create a new note containing the clipboard contents with xclip xclip -o | nb + # create a new note in the notebook named "example" nb example:a ``` ##### Other Aliases: `nb create`, `nb new` [`nb add`](#add) can also be invoked with [`nb create`](#add) and [`nb new`](#add) for convenience: ```bash # create a new note containing "Example note content." nb new "Example note content." # create a new note with the title "Example Note Title" nb create --title "Example Note Title" ``` ##### Adding with `nb browse` Items can also be added within terminal and GUI web browsers using [`nb browse add`](#browse) / [`nb b a`](#browse): ```bash ❯ nb browse add ❯nb · home : + [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [add] ``` Pass a filename, relative path, and / or notebook name to create a new note at that location: ```bash # open the add form in the browser to create the file "file.md" in the folder "example" nb browse add "example/file.md" ``` [`nb browse add`](#browse) includes options for quickly pre-populating new notes with content: ```bash ❯ nb browse add --title "Example Title" --content "Example content." --tags tag1,tag2 ❯nb · home : + [# Example Title ] [ ] [#tag1 #tag2 ] [ ] [Example content. ] [ ] [ ] [ ] [ ] [ ] [add] ``` [`nb browse add`](#browse) can also be opened with [`nb add --browse`](#add) / [`nb a -b`](#add). For more information, see [Browsing](#-browsing). #### Listing & Filtering <a href="#overview">↑</a> · <a href="#ls"><code>nb ls</code></a>, <a href="#list"><code>nb list</code></a>, <a href="#browse"><code>nb browse</code></a> To list notes and notebooks, run [`nb ls`](#ls) (shortcut alias: `nb`): <div align="center"> <img src="https://xwmx.github.io/misc/nb/images/nb-theme-utility-home.png" alt="nb ls" width="450"> </div> Notebooks are listed above the line, with the current notebook highlighted and/or underlined, depending on terminal capabilities. [`nb ls`](#ls) also includes a footer with example commands for easy reference. The notebook header and command footer can be configured or hidden with [`nb set header`](#header) and [`nb set footer`](#footer). ```bash ❯ nb ls home ---- [3] example.md · "Example content." [2] sample.md · "Sample content." [1] demo.md · "- Demo list item one." ``` Notes from the current notebook are listed in the order they were last modified. By default, each note is listed with its id, filename, and an excerpt from the first line of the note. When a note has a title, the title is displayed instead of the filename and first line. Markdown titles can be defined within a note using [either Markdown `h1` style](https://daringfireball.net/projects/markdown/syntax#header) or [YAML front matter](#front-matter): ```markdown # Example Title ``` ```markdown Sample Title ============ ``` ```markdown --- title: Demo Title --- ``` [Org](https://orgmode.org/), [LaTeX](https://www.latex-project.org/), and [AsciiDoc](https://asciidoc.org/) titles are recognized in `.org`,`.latex`, and `.asciidoc` / `.adoc` files: ```text #+title: Example Org Title ``` ```latex \title{Example LaTeX Title} ``` ```asciidoc = Example AsciiDoc Title ``` Once defined, titles are displayed in place of the filename and first line in the output of [`nb ls`](#ls): ```bash ❯ nb ls home ---- [3] Example Title [2] Sample Title [1] Demo Title ``` Pass an id, filename, or title to view the listing for that note: ```bash ❯ nb ls Sample\ Title [2] Sample Title ❯ nb ls 3 [3] Example Title ``` If there is no exact match, `nb` will list items with titles and filenames that fuzzy match the query: ```bash ❯ nb ls exa [3] Example Title ❯ nb ls ample [3] Example Title [2] Sample Title ``` Multiple words act like an `OR` filter, listing any titles or filenames that match any of the words: ```bash ❯ nb ls example demo [3] Example Title [1] Demo Title ``` When multiple words are quoted, filter titles and filenames for that phrase: ```bash ❯ nb ls "example title" [3] Example Title ``` For full text search, see [Search](#-search). To view excerpts of notes, use the [`--excerpt`](#ls) or [`-e`](#ls) option, which optionally accepts a length: ```bash ❯ nb ls 3 --excerpt [3] Example Title ----------------- # Example Title This is an example excerpt. ❯ nb ls 3 -e 8 [3] Example Title ----------------- # Example Title This is an example excerpt. More example content: - one - two ``` Several classes of file types are represented with emoji [indicators](#indicators) to make them easily identifiable in lists. For example, bookmarks and encrypted notes are listed with `🔖` and `🔒`: ```bash ❯ nb ls home ---- [4] Example Note [3] 🔒 encrypted-note.md.enc [2] 🔖 Example Bookmark (example.com) [1] 🔖 🔒 encrypted.bookmark.md.enc ``` File types include: ```text 🔉 Audio 📖 Book 🔖 Bookmark 🔒 Encrypted 📂 Folder 🌄 Image 📄 PDF, Word, or Open Office document 📹 Video ``` By default, items are listed starting with the most recently modified. To reverse the order, use the [`-r`](#ls) or [`--reverse`](#ls) flag: ```bash ❯ nb ls home ---- [2] Todos [3] Example Title [1] Ideas ❯ nb ls --reverse [1] Ideas [3] Example Title [2] Todos ``` Notes can be sorted with the [`-s`](#ls) / [`--sort`](#ls) flag, which can be combined with [`-r`](#ls) / [`--reverse`](#ls): ```bash ❯ nb ls home ---- [2] Sample Title [3] Example Title [1] Demo Title ❯ nb ls --sort [1] Demo Title [2] Sample Title [3] Example Title ❯ nb ls --sort --reverse [3] Example Title [2] Sample Title [1] Demo Title ``` `nb` with no subcommand behaves like an alias for [`nb ls`](#ls), so the examples above can be run without the `ls`: ```bash ❯ nb home ---- [2] Sample Title [3] Example Title [1] Demo Title ❯ nb example [3] Example Title ❯ nb 3 --excerpt [3] Example Title ----------------- # Example Title This is an example excerpt. ❯ nb 3 -e 8 [3] Example Title ----------------- # Example Title This is an example excerpt. More example content: - one - two ❯ nb --sort [1] Demo Title [2] Sample Title [3] Example Title ❯ nb --sort --reverse [3] Example Title [2] Sample Title [1] Demo Title ``` Short options can be combined for brevity: ```bash # equivalent to `nb --sort --reverse --excerpt 2` and `nb -s -r -e 2`: ❯ nb -sre 2 [3] Example Title ----------------- # Example Title [2] Sample Title ---------------- Sample Title ============ [1] Demo Title -------------- --- title: Demo Title ``` `nb` and [`nb ls`](#ls) display the 15 most recently modified items. The default limit can be changed with [`nb set limit <number>`](#limit). To list a different number of items on a per-command basis, use the [`-n <limit>`](#ls), [`--limit <limit>`](#ls), [`--<limit>`](#ls), [`-a`](#ls), and [`--all`](#ls) flags: ```bash ❯ nb -n 1 home ---- [5] Example Five 4 omitted. 5 total. ❯ nb --limit 2 home ---- [5] Example Five [4] Example Four 3 omitted. 5 total. ❯ nb --3 home ---- [5] Example Five [4] Example Four [3] Example Three 2 omitted. 5 total. ❯ nb --all home ---- [5] Example Five [4] Example Four [3] Example Three [2] Example Two [1] Example One ``` Lists can be paginated with [`-p <number>`](#ls) / [`--page <number>`](#ls), which paginates by the value of [`nb set limit`](#limit) by default, or the value of [`-n <limit>`](#ls), [`--limit <limit>`](#ls), or [`--<limit>`](#ls) when present: ```bash ❯ nb home ---- [6] Example Six [5] Example Five [4] Example Four [3] Example Three [2] Example Two [1] Example One ❯ nb set limit 3 NB_LIMIT set to 3 ❯ nb --page 1 [6] Example Six [5] Example Five [4] Example Four ❯ nb -p 2 [3] Example Three [2] Example Two [1] Example One ❯ nb -p 2 --limit 2 [4] Example Four [3] Example Three ❯ nb -p 3 --2 [2] Example Two [1] Example One ``` List [#tagged](#tagging) items by passing `\#escaped` or `"#quoted"` hashtags or tags specified with the [`--tags`](#ls) option.

[2] Example Two [1] Example One ``` For more information about options for listing notes, run [`nb help ls`](#ls) and [`nb help list`](#list). ##### Listing with `browse` Items can be listed within terminal and GUI web browsers using [`nb browse`](#browse) / [`nb b`](#browse): ```bash ❯ nb browse example:sample/demo/ ❯nb · example : sample / demo / + search: [ ] [example:sample/demo/7] Title Seven [example:sample/demo/6] Title Six [example:sample/demo/5] Title Five [example:sample/demo/4] Title Four [example:sample/demo/3] Title Three next ❯ ``` For more information, see [Browsing](#-browsing). #### Editing <a href="#overview">↑</a> · <a href="#edit"><code>nb edit</code></a>, <a href="#browse"><code>nb browse edit</code></a> You can edit an item in your editor with [`nb edit`](#edit) (shortcut: [`nb e`](#edit)): ```bash # edit note by id nb edit 3 # edit note by filename nb edit example.md # edit note by title nb edit "A Document Title" # edit note 12 in the notebook named "example" nb edit example:12 # edit note 12 in the notebook named "example", alternative nb example:12 edit # edit note 12 in the notebook named "example", alternative nb example:edit 12 ``` [`edit`](#edit) and other subcommands that take an identifier can be called with the identifier and subcommand name reversed: ```bash # edit note by id nb 3 edit ``` [`nb edit`](#edit) can also receive piped content, which it appends to the specified note without opening the editor: ```bash echo "Content to append." | nb edit 1 ``` Content can be passed with the [`--content <content>`](#edit) option, which also appends the content without opening the editor: ```bash nb edit 1 --content "Content to append." ``` Use the [`--overwrite`](#edit) option to overwrite existing file content and the [`--prepend`](#edit) option to prepend the new content before existing content. When content is piped or specified with [`--content <content>`](#edit), use the [`--edit`](#edit) flag to open the file in the editor before the change is committed. ##### Editing Encrypted Notes When a note is encrypted, [`nb edit`](#edit) prompts you for the note password, opens the unencrypted content in your editor, and then automatically reencrypts the note when you are done editing. ##### Shortcut Alias: `nb e` [`nb edit`](#edit) can be called by the shortcut alias, [`nb e`](#edit): ```bash # edit note by id nb e 3 # edit note by filename nb e example.md # edit note by title nb e "A Document Title" # edit note by id, alternative nb 3 e # edit note 12 in the notebook named "example" nb e example:12 # edit note 12 in the notebook named "example", alternative nb example:12 e # edit note 12 in the notebook named "example", alternative nb example:e 12 ``` For [`nb edit`](#edit) help information, run [`nb help edit`](#edit). ##### Editing with `browse` Items can be edited within terminal and GUI web browsers using [`nb browse edit`](#browse) / [`nb b e`](#browse): ```bash ❯ nb browse edit text:formats/markdown/123 ❯nb · text : formats / markdown / 123 · ↓ · editing · - | + [# Daring Fireball: Markdown (daringfireball.net) ] [ ] [<https://daringfireball.net/projects/markdown/> ] [ ] [## Related ] [ ] [- <https://en.wikipedia.org/wiki/Markdown> ] [ ] [## Comments ] [ ] [See also: ] [ ] [- [[text:formats/org]] ] [- [[cli:apps/nb]] ] [ ] [## Tags ] [ ] [save] · last: 2021-01-01 01:00:00 ``` For more information, see [`browse edit`](#browse-edit) and [Browsing](#-browsing). #### Viewing <a href="#overview">↑</a> · <a href="#show"><code>nb show</code></a>, <a href="#browse"><code>nb browse</code></a>, <a href="#open"><code>nb open</code></a>, <a href="#peek"><code>nb peek</code></a> Notes and other items can be viewed using [`nb show`](#show) (shortcut: [`nb s`](#show)): ```bash # show note by id nb show 3 # show note by filename nb show example.md # show note by title nb show "A Document Title" # show note by id, alternative nb 3 show # show note 12 in the notebook named "example" nb show example:12 # show note 12 in the notebook named "example", alternative nb example:12 show # show note 12 in the notebook named "example", alternative nb example:show 12 ``` By default, [`nb show`](#show) opens notes in [`less`](https://linux.die.net/man/1/less), with syntax highlighting if [`bat`](https://github.com/sharkdp/bat), [`highlight`](http://www.andre-simon.de/doku/highlight/en/highlight.php), or [Pygments](https://pygments.org/) is installed.

To create a new bookmark, pass a URL as the first argument to `nb`: ```bash nb https://example.com ``` `nb` automatically generates a bookmark using information from the page: ```markdown # Example Title (example.com) <https://example.com> ## Description Example description. ## Content Example Title ============= This domain is for use in illustrative examples in documents. You may use this domain in literature without prior coordination or asking for permission. [More information\...](https://www.iana.org/domains/example) ``` `nb` embeds the page content in the bookmark, making it available for [full text search](#-search) with [`nb search`](#search) and locally-served, distraction-free [reading and browsing](#-browsing) with [`nb browse`](#browse). When [Pandoc](https://pandoc.org/) is installed, the HTML page content is converted to Markdown. When [readability-cli](https://gitlab.com/gardenappl/readability-cli) is installed, markup is cleaned up to focus on content. When [Chromium](https://www.chromium.org) or [Chrome](https://www.google.com/chrome/) is installed, JavaScript-dependent pages are rendered and the resulting markup is saved. Many shells automatically escape special characters in URLs. If a URL contains characters that are preventing it from being saved in full, URLs can also be enclosed in quotes when passed to `nb`: ```bash nb "https://example.com#sample-anchor" ``` In addition to caching the page content, you can also include a quote from the page in a [`## Quote`](#-quote) section using the [`-q <quote>`](#bookmark) / [`--quote <quote>`](#bookmark) option: ```bash nb https://example.com --quote "Example quote line one. Example quote line two." ``` ```markdown # Example Title (example.com) <https://example.com> ## Description Example description. ## Quote > Example quote line one. > > Example quote line two. ## Content Example Title ============= This domain is for use in illustrative examples in documents.

Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML). ``` For more information, see [Browsing](#-browsing). [`nb open`](#open) (shortcut: [`nb o`](#open)) opens the bookmarked URL in your system's primary web browser: ```bash # open bookmark by id nb open 3 # open bookmark 12 in the notebook named "example" nb open example:12 # open bookmark 12 in the notebook named "example", alternative nb example:12 open # open bookmark 12 in the notebook named "example", alternative nb example:open 12 ``` *N.B. To use [`nb open`](#open) with [WSL](https://docs.microsoft.com/en-us/windows/wsl/install), install [wslu](https://github.com/wslutilities/wslu).* [`nb peek`](#peek) (shortcut: [`nb p`](#peek), alias: [`nb preview`](#peek)) opens the bookmarked URL in your terminal web browser, such as [w3m](https://en.wikipedia.org/wiki/W3m), [Links](https://en.wikipedia.org/wiki/Links_(web_browser)), or [Lynx](https://en.wikipedia.org/wiki/Lynx_(web_browser)): ```bash # peek bookmark by id nb peek 3 # peek bookmark 12 in the notebook named "example" nb peek example:12 # peek bookmark 12 in the notebook named "example", alternative nb example:12 peek # peek bookmark 12 in the notebook named "example", alternative nb example:peek 12 ``` [`nb open`](#open) and [`nb peek`](#peek) work seamlessly with encrypted bookmarks. `nb` simply prompts you for the bookmark's password. [`nb open`](#open) and [`nb peek`](#peek) automatically check whether the URL is still valid. If the page has been removed, `nb` can check the [Internet Archive Wayback Machine](https://archive.org/web/) for an archived copy. The preferred terminal web browser can be set using the `$BROWSER` environment variable, assigned in `~/.bashrc`, `~/.zshrc`, or similar: ```bash export BROWSER=lynx ``` When `$BROWSER` is not set, `nb` looks for [`w3m`](https://en.wikipedia.org/wiki/W3m), [`links`](https://en.wikipedia.org/wiki/Links_(web_browser)), and [`lynx`](https://en.wikipedia.org/wiki/Lynx_(web_browser)) and uses the first one it finds. `$BROWSER` can also be used to easy specify the terminal browser for an individual command: ```bash ❯ BROWSER=links nb 12 peek # opens the URL from bookmark 12 in links ❯ BROWSER=w3m nb 12 peek # opens the URL from bookmark 12 in w3m ``` [`nb show`](#show) and [`nb edit`](#edit) can also be used to view and edit bookmark files, which include the cached page converted to Markdown. [`nb show <id> --render`](#show) / [`nb show <id> -r`](#show) displays the bookmark file converted to HTML in the terminal web browser, including all bookmark fields and the cached page content, providing a cleaned-up, distraction-free, locally-served view of the page content along with all of your notes. ##### Shortcut Aliases: `nb o` and `nb p` [`nb open`](#open) and [`nb peek`](#peek) can also be used with the shortcut aliases [`nb o`](#open) and [`nb p`](#peek): ```bash # open bookmark by id nb o 3 # open bookmark 12 in the notebook named "example" nb o example:12 # open bookmark 12 in the notebook named "example", alternative nb example:12 o # peek bookmark by id nb p 3 # peek bookmark 12 in the notebook named "example" nb p example:12 # peek bookmark 12 in the notebook named "example", alternative nb example:12 p ``` #### Bookmark File Format Bookmarks are identified by a `.bookmark.md` file extension. The bookmark URL is the first URL in the file within `<` and `>` characters. To create a minimally valid bookmark file with [`nb add`](#add): ```bash nb add example.bookmark.md --content "<https://example.com>" ``` For a full overview, see [`nb` Markdown Bookmark File Format](#nb-markdown-bookmark-file-format). #### `bookmark` -- A command line tool for managing bookmarks. `nb` includes [`bookmark`](#bookmark-help), a full-featured command line interface for creating, viewing, searching, and editing bookmarks. [`bookmark`](#bookmark-help) is a shortcut for the [`nb bookmark`](#bookmark) subcommand, accepting all of the same subcommands and options with identical behavior. Bookmark a page: ```bash ❯ bookmark https://example.com --tags tag1,tag2 Added: [3] 🔖 20200101000000.bookmark.md "Example Title (example.com)" ``` List and filter bookmarks with [`bookmark`](#bookmark) and [`bookmark list`](#bookmark): ```bash ❯ bookmark Add: bookmark <url> Help: bookmark help --------------------------------------- [3] 🔖 🔒 example.bookmark.md.enc [2] 🔖 Example Two (example.com) [1] 🔖 Example One (example.com) ❯ bookmark list two [2] 🔖 Example Two (example.com) ``` View a bookmark in your terminal web browser: ```bash bookmark peek 2 ``` Open a bookmark in your system's primary web browser: ```bash bookmark open 2 ``` Perform a full text search of bookmarks and archived page content: ```bash ❯ bookmark search "example query" [10] 🔖 example.bookmark.md "Example Bookmark (example.com)" ------------------------------------------------------------ 5:Lorem ipsum example query. ``` See [`bookmark help`](#bookmark-help) for more information. ### ✅ Todos <a href="#overview">↑</a> · <a href="#do"><code>nb do</code></a>, <a href="#tasks"><code>nb tasks</code></a>, <a href="#todo"><code>nb todo</code></a>, <a href="#undo"><code>nb undo</code></a> Use [`nb todo`](#todo) (shortcut: [`nb to`](#todo)) to create, list, and update todos. `nb` todos are [structured Markdown documents](#nb-markdown-todo-file-format) referencing a single primary todo, with optional [tasks](#%EF%B8%8F-tasks).

The [`nb browse`](#browse) interface includes links to quickly jump to parent folders, the current notebook, and other notebooks. [`nb browse`](#browse) opens in [w3m](https://en.wikipedia.org/wiki/W3m), [Links](https://en.wikipedia.org/wiki/Links_$web_browser$), or in the browser set in the `$BROWSER` environment variable. Use [`nb browse --gui`](#browse) / [`nb b -g`](#browse) to open in the system's primary [GUI web browser](#browse---gui). To open a specific item in [`nb browse`](#browse), pass the [selector](#-selectors) for the item, folder, or notebook to [`nb browse`](#browse): ```bash # open the item with id 42 in the folder named "sample" in the "example" notebook ❯ nb browse example:sample/42 ❯nb · example : sample / 42 · ↓ · edit | + Example Title #tag1 #tag2 Example content with link to [[Demo Title]]. More example content: • one • two • three ``` Items can also be browsed with [`nb show --browse`](#show) / [`nb s -b`](#show), which behaves identically. [`nb browse`](#browse) is particularly useful for [bookmarks](#-bookmarks). Cached content is rendered in the web browser along with comments and notes. Internal and external links are easily accessible directly in the terminal, providing a convenient, distraction-free approach for browsing collections of bookmarks. ```bash ❯ nb browse text:formats/markdown/123 ❯nb · text : formats / markdown / 123 · ↓ · edit | + Daring Fireball: Markdown (daringfireball.net) https://daringfireball.net/projects/markdown/ Related • https://en.wikipedia.org/wiki/Markdown Comments See also: • [[text:formats/org]] • [[cli:apps/nb]] Tags #markup #plain-text Content Daring Fireball: Markdown Download Markdown 1.0.1 (18 KB) — 17 Dec 2004 Introduction Markdown is a text-to-HTML conversion tool for web writers.

[`w3m`](https://en.wikipedia.org/wiki/W3m) opens items in your `$EDITOR`, then returns you back to the browser to save changes and continue browsing. Edits in [`links`](https://en.wikipedia.org/wiki/Links_(web_browser)) are performed directly in the browser. Syntax highlighting, block selection, and other [advanced editor features](#browse---gui-editing) are available with [`nb browse --gui`](#browse). #### `browse add` Add an item within the browser using the `+` link or [`nb browse add`](#browse) / [`nb b a`](#browse). Pass a notebook, folder, and / or filename selector to create a new note in that location: ```bash ❯ nb browse add text:formats/ ❯nb · text : formats / + [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [add] ``` [`nb browse add`](#browse) includes options for quickly pre-populating new notes with content: ```bash ❯ nb browse add --title "Example Title" --content "Example content." --tags tag1,tag2 ❯nb · home : + [# Example Title ] [ ] [#tag1 #tag2 ] [ ] [Example content. ] [ ] [ ] [ ] [ ] [ ] [add] ``` #### `browse delete` Use the `-` link on the [`nb browse edit`](#browse) page or [`nb browse delete`](#browse) / [`nb b d`](#browse) to delete an item: ```bash ❯ nb browse delete example:4 ❯nb · example : 4 · ↓ · edit · - | + deleting [4] example_file.md "Example Title" [delete] ``` #### `browse` Search [`nb browse`](#browse) includes a search field powered by [`nb search`](#search) that can be used to search the current notebook or folder. Search queries are treated as command line arguments for [`nb search`](#search), providing the ability to perform `AND` and `OR` queries. Use the [`-q <query>`](#browse) / [`--query <query>`](#browse) option to open [`nb browse`](#browse) to the results page for a search: ```bash # open to a list of items containing "example" in the current notebook ❯ nb browse --query "example" ❯nb · home search: [example ] [home:321] Test Title [home:654] Sample Title [home:789] Demo Title # using shortcut alias and short option ❯ nb b -q "example" ❯nb · home search: [example ] [home:321] Test Title [home:654] Sample Title [home:789] Demo Title ``` Search for [#tags](#-tagging) with the [`-t`](#browse) / [`--tag`](#browse) / [`--tags`](#browse) options: ```bash # open to a list of items tagged with "#tag2" in the current notebook ❯ nb browse --tag tag2 ❯nb · home search: [#tag2 ] [home:654] Sample Title [home:789] Demo Title # using shortcut alias and short option ❯ nb b -t tag2 ❯nb · home search: [#tag2 ] [home:654] Sample Title [home:789] Demo Title ``` For more information about search options, see [Search](#-search) and [`nb search`](#search). #### `browse --gui` To open any [`nb browse`](#browse) view in the system's primary GUI web browser, add the [`nb browse --gui`](#browse) / [`nb b -g`](#browse) option: ```bash # open the item with id 123 in the "sample" notebook in the system's primary GUI browser nb browse sample:123 --gui # open the folder named "example" in the system's primary GUI browser, # short option nb browse example/ -g # open the current notebook in the system's primary GUI browser, # shortcut alias and short option nb b -g ``` ##### `browse --gui` Editing By default, [`nb browse --gui`](#browse) uses the browser's default `<textarea>` for editing items. [Ace](https://ace.c9.io/) is a text editor for GUI web browsers that provides advanced text editing functionality, including block selection and [syntax highlighting](#gui-web-syntax-highlighting). To use Ace as the editor for [`nb browse --gui`](#browse), add the following line to your `~/.nbrc` file: ```bash export NB_ACE_ENABLED=1 ``` The next time a form is loaded in [`nb browse`](#browse), `nb` will automatically download (from [GitHub](https://github.com/ajaxorg/ace-builds/)), install, and enable the Ace editor in [`nb browse edit --gui`](#browse) and [`nb browse add --gui`](#browse). #### `browse` Portability [`nb browse`](#browse) depends on either [`socat`](https://www.kali.org/tools/socat/) or [`ncat`](https://nmap.org/ncat/) (available as part of the `ncat` or `nmap` package in most package managers) and [`pandoc`](https://pandoc.org/). When neither `socat` nor `ncat` is available and the Bash version is 5.2 or higher, [`nb browse`](#browse) falls back to a pure Bash implementation that supports all features except the Ace editor. When only `pandoc` is available, the current note is rendered and <a href="#-linking">[[wiki-style links]]</a> go to unrendered, original files. When `socat`,`ncat`, or Bash 5.2+ is available without `pandoc`, files in plain text formats are rendered with the original markup unconverted. If neither `ncat`, `socat`, Bash 5.2+, nor `pandoc` is available, [`nb browse`](#browse) falls back to the default behavior of [`nb show`](#show). When `nb` is installed on Windows, `socat` ([MSYS](https://packages.msys2.org/package/socat), [Cygwin](https://cygwin.com/packages/summary/socat.html)) is recommended. #### `browse` Privacy [`nb browse`](#browse) is completely local and self-contained within `nb`, from the CSS and JavaScript all the way down through the HTTP request parsing and response building, with no imports, libraries, frameworks, or third-party code outside of the few binary dependencies (`bash`, `git`, `ncat` / `socat`, `pandoc`), the Linux / Unix environment, and the optional [Ace editor](#ace-editor). Terminal web browsers don't use JavaScript, so visits from them are not visible to some web analytics tools. [`nb browse`](#browse) includes a number of additional features to enhance privacy and avoid leaking information: - Page content is cached locally within each bookmark file, making it readable in terminal and GUI web browsers without requesting the page again or needing to be connected to the internet. - `<img>` tags in bookmarked content are removed to avoid requests. - Outbound links are automatically rewritten to use an [exit page redirect](https://geekthis.net/post/hide-http-referer-headers/#exit-page-redirect) to mitigate leaking information via the [referer header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Referer). - All pages include the `<meta name="referrer" content="no-referrer" />` tag. - Links include a `rel="noopener noreferrer"` attribute. - `lynx` is opened with the `-noreferer` option. #### `browse` AsciiDoc To [`browse`](#browse) items in [AsciiDoc](https://asciidoc.org/) format, install [`asciidoctor`](https://asciidoctor.org/). #### Shortcut Alias: `nb b` [`nb browse`](#browse) can also be used with the alias [`nb b`](#browse): ```bash # open the current notebook in the terminal web browser nb b # open the item with id 123 in the "example" notebook using the terminal web browser nb b example:123 # open the notebook named "sample" in the GUI web browser nb b sample: -g ``` For more information, see [`nb browse`](#browse). ### 🌄 Images <a href="#overview">↑</a> · <a href="#browse"><code>nb browse</code></a>, <a href="#import"><code>nb import</code></a>, <a href="#open"><code>nb open</code></a>, <a href="#show"><code>nb show</code></a> `nb` can be used to view, organize, browse, reference, and work with images in terminals, web browsers, and GUI applications. #### Image Items [Import](#%EF%B8%8F-import--export) images with [`nb import`](#import): ```bash # import the image file "example.png" into the current notebook nb import example.png # import an image file from a URL into the current notebook nb import https://raw.githubusercontent.com/xwmx/nb/master/docs/images/nb.png # nb import "sample.jpg" into the "demo" folder in the "example" notebook nb import sample.jpg example:demo/ ``` Imported images are displayed with [`🌄` indicators](#indicators) in [lists](#listing--filtering): ```bash ❯ nb home ---- [5] Example Five [4] 🌄 example-image.png [3] Example Three [2] Example Two [1] Example One ``` Imported image items can be opened in the system GUI application for the item's file type using [`nb open`](#open): ```bash # open the image "example-image.png" in the system GUI photo viewer nb open example-image.png # open the image with id "4" in the system GUI photo viewer nb 4 o ``` Image items can be viewed in web browsers with [`nb browse`](#browse), providing a convenient mechanism for [browsing](#-browsing) notebooks and folders containing image collections. [`nb browse`](#browse) renders image items within in an `<img>` tag on the item page. Open the item page for an image item by passing a [selector](#-selectors) to [`nb browse`](#browse), optionally including the [`-g`](#browse) / [`--gui`](#browse) option to open the page in the system GUI web browser: ```bash # open item with id "123" in the terminal web browser nb browse 123 # open item with id "456" in the "example" notebook in the GUI web browser nb browse example:456 --gui # open item "example:456" in the GUI web browser, alternative nb example:456 b -g ``` The original file can be viewed or downloaded from the item page by either clicking the image item or using the down arrow (`↓`) link. [`nb browse --gui`](#browse---gui) displays images in any GUI web browser. Some terminal web browsers, such as [`w3m`](http://w3m.sourceforge.net/), can be configured to display images. [`nb show`](#show) can display images directly in the terminal with supported tools and configurations, including: - [`catimg`](https://github.com/posva/catimg) - [Chafa](https://github.com/hpjansson/chafa) - [ImageMagick](https://imagemagick.org/) with a terminal that supports [sixels](https://en.wikipedia.org/wiki/Sixel) - [`imgcat`](https://www.iterm2.com/documentation-images.html) with [iTerm2](https://www.iterm2.com/) - [kitty's `icat` kitten](https://sw.kovidgoyal.net/kitty/kittens/icat.html) - [`termvisage`](https://github.com/AnonymouX47/termvisage) - [`timg`](https://github.com/hzeller/timg) - [`viu`](https://github.com/atanunq/viu) A preferred image viewer tool can be set with the [`$NB_IMAGE_TOOL`](#nb_image_tool) variable in your `~/.nbrc` file, which can be opened in your editor with [`nb settings edit`](#settings). #### Inline Images Images can be referenced and rendered inline within notes, bookmarks, and other items. To reference an image in the same notebook, specify the image's relative path within the notebook: ```markdown # reference "example.jpg" from markdown ![](example.jpg) # reference "demo.png" in the "sample" folder from markdown ![](sample/demo.png) ``` Images in any notebook can be referenced using the `--original` URL, obtainable from the image's [`nb browse`](#browse) item page by either clicking the image item or using the down arrow (`↓`) link. ```markdown # reference "example.jpg" in the "home" notebook with the --original URL ![](http://localhost:6789/--original/home/example.jpg) ``` Image references in content are rendered inline within web browsers with [`nb browse`](#browse) and [`nb show --render`](#show). `<img>` tags are stripped from bookmarked content when rendering to HTML. Inline images can still be used in other bookmark sections like [`## Comment`](#-comment). ### 🗂 Zettelkasten <a href="#overview">↑</a> Zettelkasten (German: "slip box") is a method of note-taking and personal knowledge management modeled around a few key features: - Notes are taken liberally on index cards. - Each note is numbered for easy reference. - Index cards are organized into boxes. - Index cards can reference other index cards. - Cards can include tags and other metadata. Since `nb` works directly on plain text files organized in normal system directories in normal git repositories, `nb` is a very close digital analogue to physical zettelkasten note-taking. | Zettelkasten | `nb` | |:-----------------:|:-----------------------------------------------:| | index cards | [notes](#-notes) & [bookmarks](#-bookmarks) | | numbering | ids & [selectors](#-selectors) | | slip boxes | [notebooks](#-notebooks) | | tags | [#tags](#-tagging) | | metadata | [front matter](#front-matter) | | cross-references | <a href="#-linking">[[wiki-style links]]</a> | | fast note-taking | [`nb add`](#adding)/[`nb <url>`](#-bookmarks) | For more information about Zettelkasten, see [Wikipedia](https://en.wikipedia.org/wiki/Zettelkasten). ### 📂 Folders <a href="#overview">↑</a> · <a href="#add"><code>nb add</code></a>, <a href="#browse"><code>nb browse</code></a>, <a href="#folders"><code>nb folders</code></a>, <a href="#list"><code>nb list</code></a>, <a href="#ls"><code>nb ls</code></a> Items can be organized in folders. To add a note to a folder, call [`nb add`](#add) with the folder's relative path within the notebook followed by a slash: ```bash # add a new note in the folder named "example" nb add example/ # add a new note in the folder named "demo" in "example" nb add example/demo/ ``` `nb` automatically creates any intermediate folders as needed. Folders can be created directly using [`nb add folder`](#add), [`nb folders add`](#folders), and [`nb add --type folder`](#add): ```bash # create a new folder named "sample" nb add folder sample # create a new folder named "sample", alternative nb folders add sample # create a new folder named "demo" nb add demo --type folder # create a folder named "example" containing a folder named "test" nb add example/test --type folder ``` To list the items in a folder, pass the folder relative path to `nb`, [`nb ls`](#ls), [`nb list`](#list), or [`nb browse`](#browse) with a trailing slash: ```bash ❯ nb example/demo/ home ---- [example/demo/3] Title Three [example/demo/2] Title Two [example/demo/1] Title One ``` Folders can also be identified by the folder's id and listed with a trailing slash: ```bash ❯ nb list [1] 📂 example ❯ nb list 1/ [example/2] 📂 demo [example/1] document.md ❯ nb list 1/2/ [example/demo/3] Title Three [example/demo/2] Title Two [example/demo/1] Title One ``` Items in folders can be idenitified with the folder's relative path using either folder ids or names, followed by the id, title, or filename of the item: ```bash # list item 1 ("Title One", one.md) in the example/demo/ folder nb list example/demo/1 # edit item 1 ("Title One", one.md) in the example/demo/ folder nb edit example/2/one.md # show item 1 ("Title One", one.md) in the example/demo/ folder nb show 1/2/Title\ One # delete item 1 ("Title One", one.md) in the example/demo/ folder nb delete 1/demo/1 ``` For folders and items in other notebooks, combine the relative path with the notebook name, separated by a colon: ```bash # list the contents of the "sample" folder in the "example" notebook nb example:sample/ # add an item to the "sample/demo" folder in the "example" notebook nb add example:sample/demo/ # edit item 3 in the "sample/demo" folder in the "example" notebook nb edit example:sample/demo/3 ``` [Browse](#-browsing) starting at any folder with [`nb browse`](#browse): ```bash ❯ nb browse example:sample/demo/ ❯nb · example : sample / demo / search: [ ] [example:sample/demo/5] Title Five [example:sample/demo/4] Title Four [example:sample/demo/3] Title Three [example:sample/demo/2] Title Two [example:sample/demo/1] Title One ``` For more information about identifying folders, see [Selectors](#-selectors). ### 📌 Pinning <a href="#overview">↑</a> · <a href="#pin"><code>nb pin</code></a>, <a href="#unpin"><code>nb unpin</code></a>, <a href="#ls"><code>nb ls</code></a>, <a href="#browse"><code>nb browse</code></a> Items can be pinned so they appear first in `nb`, [`nb ls`](#ls), and [`nb browse`](#browse): ```bash ❯ nb home ---- [2] 📌 Title Two [5] Title Five [4] Title Four [3] Title Three [1] Title One ``` Use [`nb pin`](#pin) and [`nb unpin`](#unpin) to pin and unpin items: ```bash ❯ nb home ---- [5] Title Five [4] Title Four [3] Title Three [2] Title Two [1] Title One ❯ nb pin 4 Pinned: [4] four.md "Title Four" ❯ nb pin 1 Pinned: [1] one.md "Title One" ❯ nb home ---- [4] 📌 Title Four [1] 📌 Title One [5] Title Five [3] Title Three [2] Title Two ❯ nb unpin 4 Unpinned: [4] four.md "Title Four" ❯ nb home ---- [1] 📌 Title One [5] Title Five [4] Title Four [3] Title Three [2] Title Two ``` `nb` can also be configured to pin notes that contain a specified [#hashtag](#-tagging) or other search pattern. To enable tag / search-based pinning, set the [`$NB_PINNED_PATTERN`](#nb_pinned_pattern) environment variable to the desired [#tag](#-tagging) or pattern. For example, to treat all items tagged with `#pinned` as pinned items, add the following line to your `~/.nbrc` file, which can be opened in your editor with [`nb settings edit`](#settings): ```bash export NB_PINNED_PATTERN="#pinned" ``` All [indicator icons](#indicators) in `nb` can be customized, so to use a different character as the pindicator, simply add a line like the following to your `~/.nbrc` file: ```bash export NB_INDICATOR_PINNED="💖" ``` ```bash ❯ nb home ---- [1] 💖 Title One [5] Title Five [4] Title Four [3] Title Three [2] Title Two ``` To bump an item to the top of the list without pinning, use the [`bump` plugin](#bump). ### 🔍 Search <a href="#overview">↑</a> · <a href="#search"><code>nb search</code></a> Use [`nb search`](#search) (shortcut: [`nb q`](#search)) to perform full text searches, with support for regular expressions, [#tags](#-tagging), and `AND`, `OR`, and `NOT` queries: ```bash # search current notebook for "example query" nb search "example query" # search the notebook "example" for "example query" nb search example: "example query" # search the folder named "demo" for "example query" nb search demo/ "example query" # search all unarchived notebooks for "example query" and list matching items nb search "example query" --all --list # search for "example" AND "demo" with multiple arguments nb search "example" "demo" # search for "example" AND "demo" with option nb search "example" --and "demo" # search for "example" OR "sample" with argument nb search "example|sample" # search for "example" OR "sample" with option nb search "example" --or "sample" # search for items matching both "Example" AND "Sample", and NOT "Demo" nb search "Example" --and "Sample" --not "Demo" # search items containing the hashtag "#example" nb search "#example" # search with a regular expression nb search "\d\d\d-\d\d\d\d" # search bookmarks for "example" nb search "example" --type bookmark # search bookmarks for "example", alternative nb bk q "example" # search the current notebook for "example query" nb q "example query" # search the notebook named "example" for "example query" nb q example: "example query" # search all unarchived notebooks for "example query" and list matching items nb q -la "example query" ``` [`nb search`](#search) prints the id number, filename, and title of each matched file, followed by each search query match and its line number, with color highlighting: ```bash ❯ nb search "example" [314] 🔖 example.bookmark.md "Example Bookmark (example.com)" -------------------------------------------------------------- 1:# Example Bookmark (example.com) 3:<https://example.com> [2718] example.md "Example Note" -------------------------------- 1:# Example Note ``` To just print the note information line without the content matches, use the [`-l`](#search) or [`--list`](#search) option: ```bash ❯ nb search "example" --list [314] 🔖 example.bookmark.md "Example Bookmark (example.com)" [2718] example.md "Example Note" ``` Multiple query arguments are treated as `AND` queries, returning items that match all queries. `AND` queries can also be specified with the [`--and <query>`](#search) option: ```bash # search for items tagged with "#example" AND "#demo" AND "#sample" using # multiple arguments nb q "#example" "#demo" "#sample" # options nb q "#example" --and "#demo" --and "#sample" ``` `nb` matches `AND` query terms regardless of where they appear in a document, an improvement over most approaches for performing `AND` queries with command line tools, which typically only match terms appearing on the same line. `OR` queries return items that match at least one of the queries and can be created by separating terms in a single argument with a pipe character `|` or with the [`--or <query>`](#search) option: ```bash # search for "example" OR "sample" with argument nb q "example|sample" # search for "example" OR "sample" with option nb q "example" --or "sample" ``` [`--or`](#search) and [`--and`](#search) queries can be used together: ```bash nb q "example" --or "sample" --and "demo" # equivalent: example|sample AND demo|sample ``` `NOT` queries exclude items that match the specified query and are specified with [`--not <query>`](#search), which can be used with `--and` and `--or`: ```bash # search for items that match "Example", excluding items that also match "Sample" nb search "Example" --not "Sample" # search for items matching both "Example" AND "Sample", and NOT "Demo" nb search "Example" --and "Sample" --not "Demo" ``` Search for [#tags](#-tagging) with flexible [`nb search --tags [<tags>]`](#search) / [`nb q -t [<tags>]`](#search) options: ```bash # search for tags in the current notebook nb search --tags # search for tags in the "sample" notebook, shortcut alias nb sample:q --tags # search for items tagged with "#tag1" nb search --tag tag1 # search for items tagged with "#tag1", shortcut alias and short option nb q -t tag1 #

search for items in the "sample" notebook tagged with "#tag1" AND "#tag2" nb sample:q --tags tag1,tag2 # search for items in the current notebook tagged with "#tag1" AND "#tag2" nb q --tag tag1 --tag tag2 # search for items in the current notebook tagged with "#tag1" OR "#tag2" nb q -t tag1 --or -t tag2 # search for items tagged with "#tag1" AND "#tag2" AND "#tag3" nb q -t tag1 --tags tag2,tag3 # search for items tagged with "#tag1" OR "#tag2" OR "#tag3" nb q -t tag1 --or --tags tag2,tag3 # search for items tagged with "#tag1" OR "#tag2" OR "#tag3" nb q \#tag1 --or -t tag2 --or "#tag3" ``` [`nb search`](#search) leverages Git's powerful built-in [`git grep`](https://git-scm.com/docs/git-grep). `nb` also supports performing searches with alternative search tools using the [`--utility <name>`](#search) option. Supported alternative search tools: - [`rga`](https://github.com/phiresky/ripgrep-all) - [`rg`](https://github.com/BurntSushi/ripgrep) - [`ag`](https://github.com/ggreer/the_silver_searcher) - [`ack`](https://beyondgrep.com/) - [`grep`](https://en.wikipedia.org/wiki/Grep) ##### Shortcut Alias: `nb q` [`nb search`](#search) can also be used with the alias [`nb q`](#search) (for "query"): ```bash # search for "example" and print matching excerpts nb q "example" # search for "example" and list each matching file nb q -l "example" # search for "example" in all unarchived notebooks nb q -a "example" # search for "example" in the notbook named "sample" nb sample:q "example" ``` For more information about search, see [`nb help search`](#search). ##### Searching with `browse` Searches can be performed within terminal and GUI web browsers using [`nb browse --query`](#browse) / [`nb b -q`](#browse): ```bash ❯ nb browse --query "#example" ❯nb · home : + search: [#example ] [home:7] Title Seven [home:32] Title Thirty-Two [home:56] Title Fifty-Six [home:135] Title One Hundred and Thirty-Five ``` For more information, see [Browsing](#-browsing). ### ↔ Moving & Renaming <a href="#overview">↑</a> · <a href="#move"><code>nb move</code></a>, <a href="#copy"><code>nb copy</code></a> Use [`nb move`](#move) (alias: [`nb rename`](#move), shortcut: [`nb mv`](#move)) to move and rename items: ```bash # move "example.md" to "sample.org" nb move example.md sample.org # rename note 2 ("example.md") to "New Name.md" nb rename 2 "New Name" ``` Items can be moved between notebooks and folders: ```bash # move note 12 from the "example" notebook into "Sample Folder" in the "demo" notebook nb move example:12 demo:Sample\ Folder/ ``` When the file extension is omitted, the existing extension is used: ```bash # rename "example.bookmark.md" to "New Name.bookmark.md" nb move example.bookmark.md "New Name" ``` When only a file extension is specified, only the extension is updated: ```bash # change the file extension of note 5 ("demo file.md") to .org ("demo file.org") nb rename 5 .org ``` Use [`nb rename --to-bookmark`](#move) to change the extension of a note to `.bookmark.md`, [`nb rename --to-todo`](#move) to change the extension to `.todo.md`, and [`nb rename --to-note`](#move) to change the extension of a bookmark or todo to either `.md` or the extension set with [`nb set default_extension`](#default_extension): ```bash # rename note 3 ("example.md") to a bookmark named "example.bookmark.md" nb rename 3 --to-bookmark # rename bookmark 6 ("sample.bookmark.md") to a note named "sample.md" nb rename 6 --to-note # rename note 7 ("demo.md") to a todo named "demo.todo.md" nb rename 7 --to-todo ``` Use [`nb rename --to-title`](#move) to set the filename to the note title, lowercased with spaces and disallowed filename characters replaced with underscores: ```bash ❯ nb rename 12 --to-title Moving: [12] 20210101010000.md "Example Title" To: example_title.md Proceed? [y/N] ``` Copy an item to a destination notebook, folder path, or filename with [`nb copy`](#copy) (alias: [`nb duplicate`](#copy)): ```bash # copy item 456 to "sample.md" nb copy 456 sample.md # copy item 678 to the "example" notebook nb copy 678 example: # copy item 789 to the "demo" folder nb copy 789 demo/ # copy item 543 to test.md in the "sample" folder in the "example" notebook nb copy 543 example:sample/test.md ``` Omit a destination to copy the item in place: ```bash # copy item 123 ("example.md") to example-1.md ❯ nb copy 123 Added: [124] example-1.md # copy item 123 ("example.md") to example-2.md, alias ❯ nb duplicate 123 Added: [125] example-2.md ``` For more information about moving, renaming, and copying items, see [`nb help move`](#move) and [`nb help copy`](#copy). ### 🗒 Revision History <a href="#overview">↑</a> · <a href="#history"><code>nb history</code></a>, <a href="#notebooks"><code>nb notebooks</code></a> Whenever a note is added, modified, or deleted, `nb` automatically commits the change to git transparently in the background. Use [`nb history`](#history) to view the revision history of any notebook, folder, or item: ```bash # show history for current notebook nb history # show history for note number 4 nb history 4 # show history for note with filename example.md nb history example.md # show history for note titled "Example" nb history Example # show history for the notebook named "example" nb example:history # show history for the notebook named "example", alternative nb history example: # show the history for note 12 in the notebook named "example" nb history example:12 ``` [`nb history`](#history) uses `git log` by default and prefers [`tig`](https://github.com/jonas/tig) when available. #### Authorship By default, git commits are attributed to the email and name configured in your [global `git` configuration](https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration). Change the email and name used for a notebook with [`nb notebooks author`](#notebooks): ```bash # edit the commit author email and name for the current notebook ❯ nb notebooks author Current configuration for: home -------------------------- email (global): example@example.test name (global): Example Name Update? [y/N] # edit the commit author email and name for the notebook named "example" ❯ nb notebooks author example Current configuration for: example -------------------------- email (global): example@example.test name (global): Example Name Update? [y/N] ``` The updated author email and name applies to subsequent commits. To use a different email and name from the beginning of a notebook's history, create the new notebook using [`nb notebooks add --author`](#notebooks) or [`nb notebooks init --author`](#notebooks). ### 📚 Notebooks <a href="#overview">↑</a> · <a href="#notebooks"><code>nb notebooks</code></a>, <a href="#archive"><code>nb archive</code></a>, <a href="#unarchive"><code>nb unarchive</code></a>, <a href="#use"><code>nb use</code></a> You can create additional notebooks, each of which has its own version history. Create a new notebook with [`nb notebooks add`](#notebooks): ```bash # add a notebook named example nb notebooks add example ``` `nb` and [`nb ls`](#ls) list the available notebooks above the list of notes: ```bash ❯ nb example · home -------------- [3] Title Three [2] Title Two [1] Title One ``` Commands in `nb` run within the current notebook, and identifiers such as ids, filenames, and titles refer to notes within the current notebook. `nb edit 3`, for example, tells `nb` to [`edit`](#edit) note with id `3` within the current notebook. To switch to a different notebook, use [`nb use`](#use): ```bash # switch to the notebook named "example" nb use example ``` If you are in one notebook and you want to perform a command in a different notebook without switching to it, add the notebook name with a colon before the command name: ```bash # add a new note in the notebook "example" nb example:add # add a new note in the notebook "example", shortcut alias nb example:a # show note 5 in the notebook "example" nb example:show 5 # show note 5 in the notebook "example", shortcut alias nb example:s 5 # edit note 12 in the notebook "example" nb example:edit 12 # edit note 12 in the notebook "example", shortcut alias nb example:e 12 # search for "example query" in the notebook "example" nb example:search "example query" # search for "example query" in the notebook "example", shortcut alias nb example:q "example query" # show the revision history of the notebook "example" nb example:history ``` The notebook name with colon can also be used as a modifier to the id, filename, or title: ```bash # edit note 12 in the notebook "example" nb edit example:12 # edit note 12 in the notebook "example", shortcut alias nb e example:12 # edit note 12 in the notebook "example", alternative nb example:12 edit # edit note 12 in the notebook "example", alternative, shortcut alias nb example:12 e # show note titled "misc" in the notebook "example" nb show example:misc # show note titled "misc" in the notebook "example", shortcut alias nb s example:misc # delete note with filename "todos.md" in the notebook "example", alternative nb example:todos.md delete # delete note with filename "todos.md" in the notebook "example", alternative, # shortcut alias nb example:todos.md d ``` When a notebook name with colon is called without a subcommand, `nb` runs [`nb ls`](#ls) in the specified notebook: ```bash ❯ nb example: example · home -------------- [example:3] Title Three [example:2] Title Two [example:1] Title One ``` A bookmark can be created in another notebook by specifying the notebook name with colon, then a space, then the URL and bookmark options: ```bash # create a new bookmark in a notebook named "sample" ❯ nb sample: https://example.com --tags tag1,tag2 ``` Notes can also be moved between notebooks: ```bash # move note 3 from the current notebook to "example" nb move 3 example: # move note 5 in the notebook "example" to the notebook "sample" nb move example:5 sample: ``` ##### Example Workflow The flexibility of `nb`'s argument handling makes it easy to build commands step by step as items are listed, filtered, viewed, and edited, particularly in combination with shell history: ```bash # list items in the "example" notebook ❯ nb example: example · home -------------- [example:3] Title Three [example:2] Title Two [example:1] Title One # filter list ❯ nb example: three [example:3] Title Three # view item ❯ nb example:3 show # opens item in `less` # edit item ❯ nb example:3 edit # opens item in $EDITOR ``` ##### Notebooks and Tab Completion [`nb` tab completion](#tab-completion) is optimized for frequently running commands in various notebooks using the colon syntax, so installing the completion scripts is recommended and makes working with notebooks easy, fluid, and fun. For example, listing the contents of a notebook is usually as simple as typing the first two or three characters of the name, then pressing the `<tab>` key, then pressing `<enter>` / `<return>`: ```bash ❯ nb exa<tab> # completes to "example:" ❯ nb example: example · home -------------- [example:3] Title Three [example:2] Title Two [example:1] Title One ``` Scoped notebook commands are also available in tab completion: ```bash ❯ nb exa<tab> # completes to "example:" ❯ nb example:hi<tab> # completes to "example:history" ``` #### Notebooks, Tags, and Taxonomy `nb` is optimized to work well with a collection of notebooks, so notebooks are a good way to organize notes and bookmarks by top-level topic. [#tags](#-tagging) are searchable across notebooks and can be created ad hoc, making notebooks and tags distinct and complementary organizational systems in `nb`. Search for a tag in or across notebooks with [`nb search`](#search) / [`nb q`](#search): ```bash # search for #tag in the current notebook nb q --tag tag # search for #tag in all notebooks, short options nb q -t tag -a # search for #tag in the "example" notebook, argument nb q example: "#tag" ``` #### Global and Local Notebooks ##### Global Notebooks By default, all `nb` notebooks are global, making them always accessible in the terminal regardless of the current working directory. Global notebooks are stored in the directory configured in [`nb set nb_dir`](#nb_dir), which is `~/.nb` by default. ##### Local Notebooks `nb` also supports creating and working with local notebooks. Local notebooks are notebooks that are anywhere on the system outside of [`$NB_DIR`](#nb_dir-1). Any folder can be an `nb` local notebook, which is just a normal folder that has been initialized as a git repository and contains an `nb` .index file. Initializing a folder as an `nb` local notebook is a very easy way to add structured git versioning to any folder of documents and other files. When `nb` runs within a local notebook, the local notebook is set as the current notebook: ```bash ❯ nb local · example · home ---------------------- [3] Title Three [2] Title Two [1] Title One ``` A local notebook is always referred to by the name `local` and otherwise behaves just like a global notebook whenever a command is run from within it: ```bash # add a new note in the local notebook nb add # edit note 15 in the local notebook nb edit 15 # move note titled "Todos" from the home notebook to the local notebook nb move home:Todos local: # move note 1 from the local notebook to the home notebook nb move 1 home: # search the local notebook for <query string> nb search "query string" # search the local notebook and all unarchived global notebooks for <query string> nb search "query string" --all ``` Local notebooks can be created with [`nb notebooks init`](#notebooks): ```bash # initialize the current directory as a notebook nb notebooks init # create a new notebook at ~/example nb notebooks init ~/example # clone an existing notebook to ~/example nb notebooks init ~/example https://github.com/example/example.git ``` Local notebooks can also be created by exporting a global notebook: ```bash # export global notebook named "example" to "../path/to/destination" nb notebooks export example ../path/to/destination # alternative nb export example ../path/to/destination ``` Local notebooks can also be imported, making them global: ```bash # import notebook or folder at "../path/to/notebook" nb notebooks import ../path/to/notebook # alternative nb import ../path/to/notebook ``` [`nb notebooks init`](#notebooks) and [`nb notebooks import`](#notebooks) can be used together to easily turn any directory of existing files into a global `nb` notebook: ```bash ❯ ls example-directory ❯ nb notebooks init example-directory Initialized local notebook: /home/username/example-directory ❯ nb notebooks import example-directory Imported notebook: example-directory ❯ nb notebooks example-directory home ``` #### Archiving Notebooks <a href="#-notebooks">↑</a> · <a href="#archive"><code>nb archive</code></a>, <a href="#status"><code>nb status</code></a>, <a href="#unarchive"><code>nb unarchive</code></a> Notebooks can be archived using [`nb archive`](#archive) (shortcut: [`nb ar`](#archive)): ```bash # archive the current notebook nb archive # archive the notebook named "example" nb archive example # archive the current notebook, shortcut alias nb ar # archive the notebook named "example", shortcut alias nb ar example ``` When a notebook is archived it is not included in [`nb`](#ls) / [`nb ls`](#ls) output, [`nb search --all`](#search), or tab completion, nor synced automatically with [`nb sync --all`](#sync). ```bash ❯ nb example1 · example2 · example3 · [1 archived] --------------------------------------------- [3] Title Three [2] Title Two [1] Title One ``` Archived notebooks can still be used individually using normal notebook commands: ```bash # switch the current notebook to the archived notebook "example" nb use example # run the `list` subcommand in the archived notebook "example" nb example:list ``` Check a notebook's archival status with [`nb status`](#status) (shortcut: [`nb st`](#status)) and [`nb notebooks status`](#notebooks): ```bash # print status information, including archival status, for the current notebook nb status # print status information, including archival status, for the notebook named "example" nb status example # print status information, including archival status, for the current notebook, # shortcut alias nb st # print status information, including archival status, for the notebook named "example", # shortcut alias nb st example # print the archival status of the current notebook nb notebooks status # print the archival status of the notebook named "example" nb notebooks status example ``` Use [`nb unarchive`](#unarchive) (shortcut: [`nb unar`](#unarchive)) to unarchive a notebook: ```bash # unarchive the current notebook nb unarchive # unarchive the notebook named "example" nb unarchive example ``` For more information about working with notebooks, see [`nb help notebooks`](#notebooks), [`nb help archive`](#archive), and [`nb help unarchive`](#unarchive). For technical details about notebooks, see [`nb` Notebook Specification](#nb-notebook-specification). ### 🔄 Git Sync <a href="#overview">↑</a> · <a href="#remote"><code>nb remote</code></a>, <a href="#sync"><code>nb sync</code></a> Each notebook can be synced with a remote git repository by setting the remote URL using [`nb remote`](#remote): ```bash # set the current notebook's remote to a private GitHub repository nb remote set https://github.com/example/example # set the remote for the notebook named "example" nb example:remote set https://github.com/example/example ``` Any notebook with a remote URL will sync automatically every time a command is run in that notebook. When you use `nb` on multiple systems, you can set a notebook on each system to the same remote and `nb` will keep everything in sync in the background every time there's a change in that notebook. Since each notebook has its own git history, you can have some notebooks syncing with remotes while other notebooks are only available locally on that system. Many services provide free private git repositories, so git syncing with `nb` is easy, free, and vendor-independent. You can also sync your notes using Dropbox, Drive, Box, Syncthing, or another syncing tool by changing your `nb` directory with [`nb set nb_dir <path>`](#nb_dir), and git syncing will still work simultaneously. Clone an existing notebook by passing the URL to [`nb notebooks add`](#notebooks): ```bash # create a new notebook named "example" cloned from a private GitLab repository nb notebooks add example https://gitlab.com/example/example.git ``` Turn off syncing for a notebook by removing the remote: ```bash # remove the remote from the current notebook nb remote remove # remove the remote from the notebook named "example" nb example:remote remove ``` Automatic git syncing can be turned on or off with [`nb set auto_sync`](#auto_sync). To sync manually, use [`nb sync`](#sync): ```bash # manually sync the current notebook nb sync # manually sync the notebook named "example" nb example:sync ``` To bypass `nb` syncing and run `git` commands directly within a notebook, use [`nb git`](#git): ```bash # run `git fetch` in the current notebook nb git fetch origin # run `git status` in the notebook named "example" nb example:git status ``` #### Syncing Multiple Notebooks with One Remote Multiple notebooks can be synced to one remote using orphan branches. An [orphan branch](https://git-scm.com/docs/git-checkout#Documentation/git-checkout.txt---orphanltnewbranchgt) is a branch with a history that is independent from the repository's `main`, `master`, or equivalent primary branch history. To sync a notebook with a new orphan branch, add the remote using [`nb remote set`](#remote) and select the option to create a new orphan branch. The name of orphan branch is derived from notebook name and can alternatively be specified as an argument to [`nb remote set`](#remote): ```bash # set the remote for the current notebook to a remote URL and branch nb remote set https://github.com/xwmx/example demo-branch ``` To create a notebook using an existing orphan branch on a remote, pass the branch name to [`nb init`](#init), [`nb notebooks add`](#notebooks), or [`nb notebooks init`](#notebooks) after the URL: ```bash # initialize new "home" notebook with the branch "sample-branch" on the remote nb init https://github.com/xwmx/example sample-branch # add a new "example" notebook from the branch "example-branch" on the remote nb notebooks add example https://github.com/xwmx/example example-branch ``` To list all branches on a remote, use [`nb remote branches`](#remote): ```bash # list all branches on the current remote nb remote branches # list all branches on a remote repository identified by a URL nb remote branches "https://github.com/xwmx/example" ``` For information about assigning remotes, see [`nb help remote`](#remote). #### Private Repositories and Git Credentials Syncing with private repositories requires configuring git to not prompt for credentials. For repositories cloned over HTTPS, [credentials can be cached with git ](https://docs.github.com/en/free-pro-team@latest/github/using-git/caching-your-github-credentials-in-git). For repositories cloned over SSH, [keys can be added to the ssh-agent ](https://docs.github.com/en/free-pro-team@latest/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent). Use [`nb sync`](#sync) within a notebook to determine whether your configuration is working. If `nb sync` displays a password prompt, then follow the instructions above to configure your credentials. The password prompt can be used to authenticate, but `nb` does not cache or otherwise handle git credentials in any way, so there will likely be multiple password prompts during each sync if credentials are not configured. #### Sync Conflict Resolution `nb` handles git operations automatically, so you shouldn't ever need to use the `git` command line tool directly. `nb` merges changes when syncing and handles conflicts using a couple different strategies. When [`nb sync`](#sync) encounters a conflict in a text file and can't cleanly merge overlapping local and remote changes, `nb` saves both versions within the file separated by git conflict markers and prints a message indicating which files contain conflicting text. Use [`nb edit`](#edit) to remove the conflict markers and delete any unwanted text. For example, in the following file, the second list item was changed on two systems, and git has no way to determine which one we want to keep: ``` # Example Title - List Item apple <<<<<<< HEAD - List Item apricot ======= - List Item pluot >>>>>>> 719od01... [nb] Commit - List Item plum ``` The local change is between the lines starting with `<<<<<<<` and `=======`, while the remote change is between the `=======` and `>>>>>>>` lines. To resolve this conflict by keeping both items, simply edit the file with [`nb edit`](#edit) and remove the lines starting with `<<<<<<<`, `=======`, and `>>>>>>>`: ``` # Example Title - List Item apple - List Item apricot - List Item pluot - List Item plum ``` When `nb` encounters a conflict in a binary file, such as an encrypted note, both versions of the file are saved in the notebook as individual files, with `--conflicted-copy` appended to the filename of the version from the remote. To resolve a conflicted copy of a binary file, compare both versions and merge them manually, then delete the `--conflicted-copy`. If you do encounter a conflict that `nb` says it can't merge at all, [`nb git`](#git) and [`nb run`](#run) can be used to perform git and shell operations within the notebook to resolve the conflict manually. Please also [open an issue](https://github.com/xwmx/nb/issues/new) with any relevant details that could inform a strategy for handling any such cases automatically. ### ↕️ Import / Export <a href="#overview">↑</a> · <a href="#import"><code>nb import</code></a>, <a href="#export"><code>nb export</code></a>, <a href="#browse"><code>nb browse</code></a> Files of any type can be imported into a notebook using [`nb import`](#import) (shortcut: [`nb i`](#import)). [`nb edit`](#edit) and [`nb open`](#open) open files in your system's default application for that file type. ```bash # import an image file nb import ~/Pictures/example.png # open image in your default image viewer nb open example.png # import a .docx file nb import ~/Documents/example.docx # open .docx file in Word or your system's .docx viewer nb open example.docx ``` Multiple filenames and globbing are supported: ```bash # import all files and directories in the current directory nb import ./* # import all markdown files in the current directory nb import ./*.md # import example.md and sample.md in the current directory nb import example.md sample.md ``` [`nb import`](#import) can also download and import files directly from the web: ```bash # import a PDF file from the web nb import https://example.com/example.pdf # Imported "https://example.com/example.pdf" to "example.pdf" # open example.pdf in your system's PDF viewer nb open example.pdf ``` Some imported file types have [indicators](#indicators) to make them easier to identify in lists: ```bash ❯ nb home ---- [6] 📖 example-ebook.epub [5] 🌄 example-picture.png [4] 📄 example-document.docx [3] 📹 example-video.mp4 [2] 🔉 example-audio.mp3 [1] 📂 Example Folder ``` Notes, bookmarks, and other files can be exported using [`nb export`](#export). If [Pandoc](https://pandoc.org/) is installed, notes can be automatically converted to any of the [formats supported by Pandoc](https://pandoc.org/MANUAL.html#option--to). By default, the output format is determined by the file extension: ```bash # export a Markdown note to a .docx Microsoft Office Word document nb export example.md /path/to/example.docx # export a note titled "Movies" to an HTML web page. nb export Movies /path/to/example.html ``` For more control over the `pandoc` options, use the [`nb export pandoc`](#export) subcommand: ```bash # export note 42 as an epub with pandoc options nb export pandoc 42 --from markdown_strict --to epub -o path/to/example.epub ``` [`nb export notebook`](#export) and [`nb import notebook`](#import) can be used to export and import notebooks: ```bash # export global notebook named "example" to "../path/to/destination" nb export notebook example ../path/to/destination # import notebook or folder at "../path/to/notebook" nb import notebook ../path/to/notebook ``` [`nb export notebook`](#export) and [`nb import notebook`](#import) behave like aliases for [`nb notebooks export`](#notebooks) and [`nb notebooks import`](#notebooks), and the subcommands can be used interchangeably. For more information about imported and exported notebooks, see [Global and Local Notebooks](#global-and-local-notebooks). For [`nb import`](#import) and [`nb export`](#export) help information, see [`nb help import`](#import) and [`nb help export`](#export). #### Exporting with `browse` Items can be exported using terminal and GUI [web browsers](#-browsing). Use the down arrow (`↓`) link on the [`nb browse`](#browse) item page to download the original file: ```bash ❯ nb browse 123 ❯nb · home : 123 · ↓ | + example.pdf ``` ### ⚙️ `set` & `settings` <a href="#overview">↑</a> · <a href="#-variables">Variables</a>, <a href="#settings"><code>nb settings</code></a>, <a href="#unset"><code>nb unset</code></a> [`nb set`](#settings) and [`nb settings`](#settings) open the settings prompt, which provides an easy way to change your `nb` settings. ```bash nb set ``` To update a setting in the prompt, enter the setting name or number and then enter the new value. `nb` will add the setting to your `~/.nbrc` configuration file. #### Example: editor `nb` can be configured to use a specific command line editor using the `editor` setting. The settings prompt for a setting can be started by passing the setting name or number to [`nb set`](#settings): ```bash ❯ nb set editor [6] editor ------ The command line text editor used by `nb`. • Example Values: atom code emacs hx macdown mate micro nano pico subl vi vim EDITOR is currently set to vim Enter a new value, unset to set to the default value, or q to quit. Value: ``` A setting can also be updated without the prompt by passing both the name and value to [`nb set`](#settings): ```bash # set editor with setting name ❯ nb set editor code EDITOR set to code # set editor with setting number (6) ❯ nb set 6 code EDITOR set to code # set the color theme to blacklight ❯ nb set color_theme blacklight NB_COLOR_THEME set to blacklight # set the default `ls` limit to 10 ❯ nb set limit 10 NB_LIMIT set to 10 ``` Use [`nb settings get`](#settings) to print the value of a setting: ```bash ❯ nb settings get editor code ❯ nb settings get 6 code ``` Use [`nb unset`](#unset) or [`nb settings unset`](#settings) to unset a setting and revert to the default: ```bash ❯ nb unset editor EDITOR restored to the default: vim ❯ nb settings get editor vim ``` [`nb set`](#settings) and [`nb settings`](#settings) are aliases that refer to the same subcommand, so the two subcommand names can be used interchangeably. For more information about [`set`](#settings) and [`settings`](#settings), see [`nb help settings`](#settings). ### 🎨 Color Themes <a href="#overview">↑</a> · <a href="#color_theme"><code>nb set color_theme</code></a>, <a href="#syntax_theme"><code>nb set syntax_theme</code></a>, <a href="#color_primary"><code>nb set color_primary</code></a>, <a href="#color_secondary"><code>nb set color_secondary</code></a> `nb` uses color to highlight various interface elements, including ids and [selectors](#-selectors), the current notebook name, the shell prompt, divider lines, [syntax elements](#terminal-syntax-highlighting-theme), and links. `nb` includes several built-in color themes and also supports user-defined themes. The current color theme can be set using [`nb set color_theme`](#color_theme): ```bash nb set color_theme ``` #### Built-in Color Themes ##### `blacklight` | ![blacklight](https://xwmx.github.io/misc/nb/images/nb-theme-blacklight-home.png) | ![blacklight](https://xwmx.github.io/misc/nb/images/nb-theme-blacklight-web.png) | |:--:|:--:| | | | ##### `console` | ![console](https://xwmx.github.io/misc/nb/images/nb-theme-console-home.png) | ![console](https://xwmx.github.io/misc/nb/images/nb-theme-console-web.png) | |:--:|:--:| | | | ##### `desert` | ![desert](https://xwmx.github.io/misc/nb/images/nb-theme-desert-home.png) | ![desert](https://xwmx.github.io/misc/nb/images/nb-theme-desert-web.png) | |:--:|:--:| | | | ##### `electro` | ![electro](https://xwmx.github.io/misc/nb/images/nb-theme-electro-home.png) | ![electro](https://xwmx.github.io/misc/nb/images/nb-theme-electro-web.png) | |:--:|:--:| | | | ##### `forest` | ![forest](https://xwmx.github.io/misc/nb/images/nb-theme-forest-home.png) | ![forest](https://xwmx.github.io/misc/nb/images/nb-theme-forest-web.png) | |:--:|:--:| | | | ##### `nb` (default) | ![nb](https://xwmx.github.io/misc/nb/images/nb-theme-nb-home.png) | ![nb](https://xwmx.github.io/misc/nb/images/nb-theme-nb-web.png) | |:--:|:--:| | | | ##### `ocean` | ![ocean](https://xwmx.github.io/misc/nb/images/nb-theme-ocean-home.png) | ![ocean](https://xwmx.github.io/misc/nb/images/nb-theme-ocean-web.png) | |:--:|:--:| | | | ##### `raspberry` | ![raspberry](https://xwmx.github.io/misc/nb/images/nb-theme-raspberry-home.png) | ![raspberry](https://xwmx.github.io/misc/nb/images/nb-theme-raspberry-web.png) | |:--:|:--:| | | | ##### `smoke` | ![smoke](https://xwmx.github.io/misc/nb/images/nb-theme-monochrome-home.png) | ![smoke](https://xwmx.github.io/misc/nb/images/nb-theme-smoke-web.png) | |:--:|:--:| | | | ##### `unicorn` | ![unicorn](https://xwmx.github.io/misc/nb/images/nb-theme-unicorn-home.png) | ![unicorn](https://xwmx.github.io/misc/nb/images/nb-theme-unicorn-web.png) | |:--:|:--:| | | | ##### `utility` | ![utility](https://xwmx.github.io/misc/nb/images/nb-theme-utility-home.png) | ![utility](https://xwmx.github.io/misc/nb/images/nb-theme-utility-web.png) | |:--:|:--:| | | | #### Custom Color Themes Color themes are [`nb` plugins](#-plugins) with a `.nb-theme` file extension. `.nb-theme` files are expected to contain one `if` statement testing for the theme name and setting the color environment variables to `tput` ANSI color numbers: ```bash # turquoise.nb-theme if [[ "${NB_COLOR_THEME}" == "turquoise" ]] then export NB_COLOR_PRIMARY=43 export NB_COLOR_SECONDARY=38 fi ``` View this theme as a complete file: [`plugins/turquoise.nb-theme`](https://github.com/xwmx/nb/blob/master/plugins/turquoise.nb-theme) Themes can be installed using [`nb plugins`](#plugins): ```bash ❯ nb plugins install https://github.com/xwmx/nb/blob/master/plugins/turquoise.nb-theme Plugin installed: /home/example/.nb/.plugins/turquoise.nb-theme ``` Once a theme is installed, use [`nb set color_theme`](#color_theme) to set it as the current theme: ```bash ❯ nb set color_theme turquoise NB_COLOR_THEME set to turquoise ``` The primary and secondary colors can also be overridden individually, making color themes easily customizable: ```bash # open the settings prompt for the primary color nb set color_primary # open the settings prompt for the secondary color nb set color_secondary ``` To view a table of available colors and numbers, run: ```bash nb set colors ``` #### Terminal Syntax Highlighting Theme `nb` displays files with syntax highlighting when [`bat`](https://github.com/sharkdp/bat), [`highlight`](http://www.andre-simon.de/doku/highlight/en/highlight.php), or [Pygments](https://pygments.org/) is installed. When `bat` is installed, syntax highlighting color themes are available for both light and dark terminal backgrounds. To view a list of available themes and set the syntax highlighting color theme, use [`nb set syntax_theme`](#syntax_theme). #### GUI Web Syntax Highlighting Syntax highlighting is also available when viewing and editing items in text formats with [`nb browse --gui`](#browse---gui), which incorporates the color theme's primary color into the syntax theme: <div align="center"> <img src="https://xwmx.github.io/misc/nb/images/nb-web-pandoc-ruby-utility.png" alt="nb syntax highlighting" width="500"> </div> #### Indicators `nb` uses emoji characters to represent information about files in lists. These characters are referred to internally as "indicators" and can be customized by assigning a different character to the indicator's environment variable in your `~/.nbrc` file, which can be opened with [`nb settings edit`](#settings). For example, to use a different indicator for pinned items, add a line like the following to your `~/.nbrc` file: ```bash export NB_INDICATOR_PINNED="✨" ``` To turn off an indicator, assign the variable to an empty string: ```bash export NB_INDICATOR_PINNED="" ``` Available indicator [variables](#-variables) with default values: ```bash export NB_INDICATOR_AUDIO="🔉" export NB_INDICATOR_BOOKMARK="🔖" export NB_INDICATOR_DOCUMENT="📄" export NB_INDICATOR_EBOOK="📖" export NB_INDICATOR_ENCRYPTED="🔒" export NB_INDICATOR_FOLDER="📂" export NB_INDICATOR_IMAGE="🌄" export NB_INDICATOR_PINNED="📌" export NB_INDICATOR_TODO="✔️ " export NB_INDICATOR_TODO_DONE="✅" export NB_INDICATOR_VIDEO="📹" ``` ### $ Shell Theme Support - [`astral` Zsh Theme](https://github.com/xwmx/astral) - Displays the current notebook name in the context line of the prompt. ### 🔌 Plugins <a href="#overview">↑</a> · <a href="#plugin-help">Plugin Help</a>, <a href="#plugins"><code>nb plugins</code></a> `nb` includes support for plugins, which can be used to create new subcommands, design themes, and otherwise extend the functionality of `nb`. `nb` supports two types of plugins, identified by their file extensions: <dl> <dt><code>.nb-theme</code></dt> <dd>Plugins defining <a href="#custom-color-themes">color themes</a>.</dd> <dt><code>.nb-plugin</code></dt> <dd>Plugins defining new subcommands and adding functionality.</dd> </dl> Plugins are managed with the [`nb plugins`](#plugins) subcommand and are installed in the `${NB_DIR}/.plugins` directory. Plugins can be installed from either a URL or a path using the [`nb plugins install`](#plugins) subcommand. ```bash # install a plugin from a URL nb plugins install https://raw.githubusercontent.com/xwmx/nb/master/plugins/clip.nb-plugin # install a plugin from a standard GitHub URL nb plugins install https://github.com/xwmx/nb/blob/master/plugins/example.nb-plugin # install a theme from a standard GitHub URL nb plugins install https://github.com/xwmx/nb/blob/master/plugins/turquoise.nb-theme # install a plugin from a path nb plugins install plugins/example.nb-plugin ``` The `<url>` should be the full URL to the plugin file. `nb` also recognizes regular GitHub URLs, which can be used interchangeably with raw GitHub URLs. Installed plugins can be listed with [`nb plugins`](#plugins), which optionally takes a name and prints full paths: ```bash ❯ nb plugins clip.nb-plugin example.nb-plugin turquoise.nb-theme ❯ nb plugins clip.nb-plugin clip.nb-plugin ❯ nb plugins --paths /home/example/.nb/.plugins/clip.nb-plugin /home/example/.nb/.plugins/example.nb-plugin /home/example/.nb/.plugins/turquoise.nb-theme ❯ nb plugins turquoise.nb-theme --paths /home/example/.nb/.plugins/turquoise.nb-theme ``` Use [`nb plugins uninstall`](#plugins) to uninstall a plugin: ```bash ❯ nb plugins uninstall example.nb-plugin Plugin successfully uninstalled: /home/example/.nb/.plugins/example.nb-plugin ``` #### Creating Plugins Plugins are written in a Bash-compatible shell scripting language and have an `.nb-plugin` extension. `nb` includes a few example plugins: - [`example.nb-plugin`](https://github.com/xwmx/nb/blob/master/plugins/example.nb-plugin) - [`clip.nb-plugin`](https://github.com/xwmx/nb/blob/master/plugins/clip.nb-plugin) - [`ebook.nb-plugin`](https://github.com/xwmx/nb/blob/master/plugins/ebook.nb-plugin) Create a new subcommand in three easy steps: ##### 1. Add the new subcommand name with `_subcommands add <name>`: ```bash _subcommands add "example" ``` ##### 2. Define help and usage text with `_subcommands describe <subcommand> <usage>`: ```bash _subcommands describe "example" <<HEREDOC Usage: nb example Description: Print "Hello, World!" HEREDOC ``` ##### 3. Define the subcommand as a function, named with a leading underscore: ```bash _example() { printf "Hello, World!\\n" } ``` That's it! 🎉 View the complete plugin: [`plugins/example.nb-plugin`](https://github.com/xwmx/nb/blob/master/plugins/example.nb-plugin) With `example.nb-plugin` installed, `nb` includes an `nb example` subcommand that prints "Hello, World!" For a full example, [`clip.nb-plugin`](https://github.com/xwmx/nb/blob/master/plugins/clip.nb-plugin) add clipboard functionality to `nb` and demonstrates how to create a plugin using `nb` subcommands and simple shell scripting. You can install any plugin you create locally with [`nb plugins install <path>`](#plugins), and you can publish it on GitHub, GitLab, or anywhere else online and install it with [`nb plugins install <url>`](#plugins). #### API The `nb` API is the [command line interface](#nb-help), which is designed for composability and provides a variety of powerful options for interacting with notes, bookmarks, notebooks, and `nb` functionality. Within plugins, subcommands can be called using their function names, which are named with leading underscores. Options can be used to output information in formats suitable for parsing and processing: ```bash # print the content of note 3 to standard output with no color _show 3 --print --no-color # list all unarchived global notebook names _notebooks --names --no-color --unarchived --global # list all filenames in the current notebook _list --filenames --no-id --no-indicator # print the path to the current notebook _notebooks current --path ``` `nb` automatically scans arguments for [selectors](#-selectors) with notebook names and updates the current notebook if a valid one is found. Identifier selectors are passed to subcommands as arguments along with any subcommand options. Use [`show <selector>`](#show) to query information about the file specified in the selector. For example, to obtain the filename of a selector-specified file, use [`show <selector> --filename`](#show): ```bash _example() { local _selector="${1:-}" [[ -z "${_selector:-}" ]] && printf "Usage: example <selector>\\n" && exit 1 # Get the filename using the selector. local _filename= _filename="$(_show "${_selector}" --filename)" # Rest of subcommand function... } ``` [`notebooks current --path`](#notebooks) returns the path to the current notebook: ```bash # _example() continued: # get the notebook path local _notebook_path= _notebook_path="$(_notebooks current --path)" # print the file at "${_notebook_path}/${_filename}" to standard output cat "${_notebook_path}/${_filename}" ``` See [`clip.nb-plugin`](https://github.com/xwmx/nb/blob/master/plugins/clip.nb-plugin) for a practical example using both [`show <selector>`](#show) and [`notebooks current --path`](#notebooks) along with other subcommands called using their underscore-prefixed function names. ### `:/` Selectors <a href="#overview">↑</a> Items in `nb` are primarily identified using structured arguments called "selectors." Selectors are like addresses for notebooks, folders, and items. A selector can be as simple as an id like `123` or folder path like `example/`, or it can combine multiple elements to identify an item in a nested folder within a particular notebook, such as: ```bash cli:tools/shellcheck/home-page.bookmark.md ``` An item, folder, or notebook selector is constructed by specifying the notebook name, folder path, and / or item identifier in the following pattern: ```text notebook:folder/path/item-idenitifer ``` Represented in a [docopt](http://docopt.org/)-like format: ```text [<notebook>:][<folder-path>/][<id> | <filename> | <title>] ``` Notebooks are identified by the notebook name followed by a colon. Folder and item identifiers without a notebook name refer to items within the current notebook. When a selector consists of notebook name and colon with no folder path or item identifier, the command runs in the root folder of the notebook: ```bash # list items in the "example" notebook nb example: # add a new note named "Example Title" to the "example" notebook nb add example: --title "Example Title" # edit item with id "123" in the notebook "example" nb edit example:123 ``` A notebook selector can be combined with a subcommand name to run the command within the notebook: ```bash # list all items in the "example" notebook and display excerpts nb example:list -e # edit item with id "123" in the "example" notebook nb example:edit 123 # show the git history for the notebook named "example" nb example:history ``` Folders are identified by relative path from the notebook root. Folders can be referenced by either id or name, and segments in nested paths can mix and match names and ids: ```bash # list items in the folder named "sample" in the folder named demo" nb sample/demo/ # add a new item to the folder named "demo" in the folder with id "3" nb add 3/demo/ # show the history of the folder with id "4" in the folder named # "sample" in the notebook named "example" nb history example:sample/4/ ``` A trailing slash indicates that the command is expected to operate on the contents of the folder. When a trailing slash is omitted, the selector refers to the folder itself: ```bash ❯ nb list sample [1] 📂 sample ❯ nb list sample/ [sample/3] Title Three [sample/2] Title Two [sample/1] Title One ``` For more information about folders, see [Folders](#-folders). An item is identified by id, filename, or title, optionally preceded by notebook name or folder path: ```bash # edit item with id "123" nb edit 123 # open the item titled "demo title" in the folder with id "3" nb open 3/demo\ title # show "file.md" in the "sample" folder in the "example" notebook nb show example:sample/file.md ``` Items can also be specified using the full path: ```bash # edit "demo.md" in the "sample" folder in the "home" notebook nb edit /home/example/.nb/home/sample/demo.md ``` ##### Examples *Idenitifer Selectors* ```text 123 example.md title relative/path/to/123 relative/path/to/demo.md relative/path/to/title /full/path/to/sample.md notebook:123 notebook:example.md notebook:title notebook:relative/path/to/123 notebook:relative/path/to/demo.md notebook:relative/path/to/title ``` *Subcommand Selectors* ```text notebook: notebook:show notebook:history notebook:a notebook:q ``` ### `01` Metadata <a href="#overview">↑</a> · <a href="#show"><code>nb show</code></a> Metadata in `nb` is primarily derived from git, the filesystem, and file content. For example, displayed timestamps are derived from [`git log`](https://git-scm.com/docs/git-log), with [`nb show --added`](#show) displaying the datetime of the first commit containing the file and [`nb show --updated`](#show) displaying the datetime of the last commit in which the file was modified. Meanwhile, the file system's modified timestamp is used for sorting. `nb` also uses plain text files to store ids and state information in git, including [`.index` files](https://github.com/xwmx/nb#index-files), [`.pindex` files](https://github.com/xwmx/nb#pindex-files), and [`.archived` files](https://github.com/xwmx/nb#archived-notebooks). #### Front Matter User-defined metadata can be added to notes in `nb` using [front matter](https://jekyllrb.com/docs/front-matter/). Front matter is a simple, human accessible, and future-friendly method for defining metadata fields in plain text and is well supported in tools for working with Markdown. Front matter is defined within a Markdown file with triple-dashed lines (`---`) indicating the start and end of the block, with each field represented by a key name with a colon followed by the value: ```markdown --- title: Example Title author: xwmx year: 2021 --- Example content. More example content: - one - two - three ``` Any metadata can be placed in the front matter block. `nb` uses the `title:` field for listing, filtering, and selecting items, if one is present, and ignores any other fields. The simple `key: value` syntax is suitable for many metadata fields.

The `nb` bookmark format is intended to be readable, editable, convertible, renderable, and clearly organized for greatest accessibility. Bookmarks are identified by a `.bookmark.md` file extension. The bookmark URL is the first URL in the file within `<` and `>` characters. To create a minimally valid bookmark file with [`nb add`](#add): ```bash nb add example.bookmark.md --content "<https://example.com>" ``` This creates a file with the name `example.bookmark.md` containing: ```markdown <https://example.com> ``` In a full bookmark, information is separated into sections, with each bookmark section indicated by a Markdown `h2` heading. #### Example ````markdown # Example Title (example.com) <https://example.com> ## Description Example description. ## Quote > Example quote line one. > > Example quote line two. ## Comment Example comment. ## Related - <https://example.net> - <https://example.org> - [[example:123]] ## Tags #tag1 #tag2 ## Content Example Title ============= This domain is for use in illustrative examples in documents.

[<folder-path>] Options: --ancestors Perform the action on all folders within the notebook that are ancestors of the current folder. --commit Commit changes to git. Subcommands: add Add <filename> to the index. delete Delete <filename> from the index. edit Open the index file in `$EDITOR`. get_basename Print the filename / basename at the specified <id>. get_id Get the id for <filename>. get_max_id Get the maximum id for the folder. rebuild Rebuild the index, listing files by last modified, reversed. Some ids will change. Prefer `nb index reconcile`. reconcile Remove duplicates and update index for added and deleted files. show Print the index. update Overwrite the <existing-filename> entry with <new-filename>. verify Verify that the index matches the folder contents. Description: Manage the index for the current folder or the folder at <folder-path>, which can be passed as the final argument to any `index` subcommand. `index` is used internally by `nb` and using it manually will probably corrupt the index. If something goes wrong with an index, fix it with `nb index reconcile`. An index is a text file named '.index' in any folder within a notebook. .index contains a list of filenames and the line number of each filename represents the id. .index files are included in the git repository so ids are preserved across systems. ``` <a href="#nb-notebook-specification">↑</a> #### `.pindex` Files Any folder may contain an optional plain text file named `.pindex` containing a list of basenames from that folder, one per line, that should be treated as [pinned](#-pinning), meaning they appear first in some list operations, including `nb` and [`nb ls`](#ls). Entries are added to a `.pindex` file with [`nb pin`](#pin) and removed with [`nb unpin`](#unpin). <a href="#nb-notebook-specification">↑</a> #### Archived Notebooks A notebook is considered [archived](#archiving-notebooks) when it contains a file named `.archived` at the root level of the notebook directory. <a href="#nb-notebook-specification">↑</a> ## Tests With more than 2,200 tests spanning tens of thousands of lines, `nb` is really mostly a [test suite](https://github.com/xwmx/nb/tree/master/test). Tests run continuously [via GitHub Actions](https://github.com/xwmx/nb/actions) on recent versions of both Ubuntu and macOS to account for differences between BSD and GNU tools and Bash versions. To run the tests locally, install [Bats](https://github.com/bats-core/bats-core) and the [recommended dependencies](#optional), then run `bats test` within the project root directory. Run groups of tests with globbing, e.g., `bats test/browse*` and `bats test/folders*`. <div align="center"> <a href="#overview"> ↑ </a> </div> --- <div align="center"> Copyright (c) 2015-present · <a href="https://www.williammelody.com/">William Melody</a> · <a href="https://github.com/xwmx/nb/blob/master/LICENSE">AGPLv3</a> </div> <div align="center"> <a href="https://xwmx.github.io/nb">xwmx.github.io/nb</a> · <a href="https://github.com/xwmx/nb">github.com/xwmx/nb</a> </div> <div align="center"> 📝🔖🔒🔍📔 </div>
