description: Render an individual tiddler as a specified ContentType

(Note: The `--rendertiddler` command is deprecated in favour of the new, more flexible `--render` command)

Render an individual tiddler as a specified ContentType, defaulting to `text/html` and save it to the specified filename.

Optionally the title of a template tiddler can be specified, in which case the template tiddler is rendered with the "currentTiddler" variable set to the tiddler that is being rendered (the first parameter value).

A name and value for an additional variable may optionally also be specified.

```
--rendertiddler <title> <filename> [<type>] [<template>] [<name>] [<value>]
```

By default, the filename is resolved relative to the `output` subdirectory of the edition directory. The `--output` command can be used to direct output to a different directory.

Any missing directories in the path to the filename are automatically created.

For example, the following command saves all tiddlers matching the filter `[tag[done]]` to a JSON file titled `output.json` by employing the core template `$:/core/templates/exporters/JsonFile`.

```
--rendertiddler "$:/core/templates/exporters/JsonFile" output.json text/plain "" exportFilter "[tag[done]]"
```
