# @kitschpatrol/mdat-config [](https://npmjs.com/package/@kitschpatrol/mdat-config) [](https://opensource.org/license/mit/) **MDAT configuration for @kitschpatrol/shared-config.** ## Overview It's a shared [MDAT (Markdown Autophagic Template)](https://github.com/kitschpatrol/mdat) system config, plus a command-line tool `ksc-mdat` to perform mdat-related project initialization, linting, and fixing. > [!IMPORTANT] > > **You can use this package on its own, but it's recommended to use [`@kitschpatrol/shared-config`](https://www.npmjs.com/package/@kitschpatrol/shared-config) instead for a single-dependency and single-package approach to linting and fixing your project.** > > This package is included as a dependency in [`@kitschpatrol/shared-config`](https://www.npmjs.com/package/@kitschpatrol/shared-config), which also automatically invokes the command line functionality in this package via its `ksc` command ## Setup To use just `mdat-config` in isolation: 1. Install the basic repository configuration files in your project root. This is required for correct PNPM behavior: ```sh pnpm --package=@kitschpatrol/repo-config dlx ksc-repo init ``` 2. Add the package: ```sh pnpm add -D @kitschpatrol/mdat-config ``` 3. Add the starter `.mdatrc.ts` file to your project root, and add any customizations you'd like: ```sh pnpm exec ksc-mdat init ``` ## Usage The `mdat` binary is specified as a peer dependency, and should be installed up automatically by PNPM. You can call it directly, or use the script bundled with the config. Integrate with your `package.json` scripts as you see fit, for example: ```json { "scripts": { "lint": "ksc-mdat lint", "fix": "ksc-mdat fix" } } ``` "Fix" in this case is a slight misnomer for consistency with the other shared-config tools. It runs `mdat expand` to expand placeholder comments in your readme.md using the bundled [`mdat`](https://github.com/kitschpatrol/mdat/blob/main/packages/mdat/readme.md) expansion rules, plus custom rules provided by `mdat-config`'s `mdat.config.ts` file, plus any additional rules specified in the repository-specific `mdat.config.ts` file. ### Configuration To create a `mdat.config.ts` in your project root: ```sh pnpm exec ksc-mdat init ``` (Note that this will delete the `mdat` property in your `package.json`!) _Or_ To create a `mdat` property in `package.json`: ```sh pnpm exec ksc-mdat init --location package ``` (Note that this will delete the `mdat.config.ts` file in your project root!) ### CLI #### Command: `ksc-mdat` Kitschpatrol's Mdat shared configuration tools. This section lists top-level commands for `ksc-mdat`. Usage: ```txt ksc-mdat ``` | Command | Description | | -------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `init` | Initialize by copying starter config files to your project root or to your package.json file. | | `lint` | Validate that all Mdat content placeholders in your readme.md file(s) have been expanded and are up to date. Package-scoped. In a monorepo, it will also run in all packages below the current working directory. | | `fix` | Expand all Mdat content placeholders in your readme.md file(s). Package-scoped. In a monorepo, it will also run in all packages below the current working directory. | | `print-config` | Print the effective Mdat configuration. Package-scoped.. Searches up to the root of a monorepo if necessary.. | | Option | Description | Type | | ------------------- | ------------------- | --------- | | `--help`
`-h` | Show help | `boolean` | | `--version`
`-v` | Show version number | `boolean` | _See the sections below for more information on each subcommand._ #### Subcommand: `ksc-mdat init` Initialize by copying starter config files to your project root or to your package.json file. Usage: ```txt ksc-mdat init ``` | Option | Description | Type | Default | | ------------------- | --------------------------------- | -------------------- | -------- | | `--location` | Where to store the configuration. | `"file"` `"package"` | `"file"` | | `--help`
`-h` | Show help | `boolean` | | | `--version`
`-v` | Show version number | `boolean` | | #### Subcommand: `ksc-mdat lint` Validate that all Mdat content placeholders in your readme.md file(s) have been expanded and are up to date. Package-scoped. In a monorepo, it will also run in all packages below the current working directory. Usage: ```txt ksc-mdat lint ``` | Option | Description | Type | | ------------------- | ------------------- | --------- | | `--help`
`-h` | Show help | `boolean` | | `--version`
`-v` | Show version number | `boolean` | #### Subcommand: `ksc-mdat fix` Expand all Mdat content placeholders in your readme.md file(s). Package-scoped. In a monorepo, it will also run in all packages below the current working directory. Usage: ```txt ksc-mdat fix ``` | Option | Description | Type | | ------------------- | ------------------- | --------- | | `--help`
`-h` | Show help | `boolean` | | `--version`
`-v` | Show version number | `boolean` | #### Subcommand: `ksc-mdat print-config` Print the effective Mdat configuration. Package-scoped.. Searches up to the root of a monorepo if necessary.. Usage: ```txt ksc-mdat print-config ``` | Option | Description | Type | | ------------------- | ------------------- | --------- | | `--help`
`-h` | Show help | `boolean` | | `--version`
`-v` | Show version number | `boolean` | ### API The package also exports `fix`, `fixFile` functions for expanding Mdat comment placeholders programmatically, pre-configured with the shared Mdat configuration. The [mdat](https://github.com/kitschpatrol/mdat) project already provides a robust TypeScript API and CLI for general use cases, but these proxies are provided for convenience in @kitschpatrol/shared-config projects. ```typescript import { clearCache, fix, fixFile } from '@kitschpatrol/mdat-config' // Expand mdat placeholders in a string using the default config const expanded = await fix('\n\n') // Expand with custom rules const customExpanded = await fix(source, { 'my-rule': '**Custom content.**' }) // Expand with custom rules in a file in place await fixFile('./readme.md', { 'my-rule': '**Custom content.**' }) // Clear cached Mdat module clearCache() ``` Config is merged in priority order: shared defaults < per-call overrides (via mdat's `mergeConfig`). The Mdat module is cached internally for performance across multiple calls. Use `clearCache()` to force re-initialization. ## License [MIT](license.txt) © [Eric Mika](https://ericmika.com)
