description: Renders individual tiddlers to files

Render individual tiddlers and save the results to the specified files.

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 title of the tiddler that is being rendered.

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

```
--render <tiddler-filter> [<filename-filter>] [<render-type>] [<template>] [<name>] [<value>]
```

* ''tiddler-filter'': A filter identifying the tiddler(s) to be rendered
* ''filename-filter'': Optional filter transforming tiddler titles into pathnames. If omitted, defaults to `[is[tiddler]addsuffix[.html]]`, which uses the unchanged tiddler title as the filename
* ''template'': Optional template through which each tiddler is rendered
* ''render-type'': Optional render type: `text/html` (the default) returns the full HTML text and `text/plain` just returns the text content (ie it ignores HTML tags and other unprintable material)
* ''name'': Name of optional variable
* ''value'': Value of optional variable

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.

Notes:

* The output directory is not cleared of any existing files
* Any missing directories in the path to the filename are automatically created.
* When referring to a tiddler with spaces in its title, take care to use both the quotes required by your shell and also TiddlyWiki's double square brackets : `--render "[[Motovun Jack.jpg]]"`
* The filename filter is evaluated with the selected items being set to the title of the tiddler currently being rendered, allowing the title to be used as the basis for computing the filename. For example `[encodeuricomponent[]addprefix[static/]]` applies URI encoding to each title, and then adds the prefix `static/`
* The `--render` command is a more flexible replacement for both the `--rendertiddler` and `--rendertiddlers` commands, which are deprecated

Examples:

* `--render "[!is[system]]" "[encodeuricomponent[]addprefix[tiddlers/]addsuffix[.html]]"` -- renders all non-system tiddlers as files in the subdirectory "tiddlers" with URL-encoded titles and the extension HTML
