cauliflower-filter

cauliflower-filter
==================


broccoli-filter built on the
new rebuild() api, ensuring stable outputs across builds. Also offers test
coverage to ensure that this plugin behaves as expected.

Cauliflower-filter aims to be 100% API compatible and suitable as a drop-in
replacement of broccoli-filter.

Key Differences | cauliflower-filter | broccoli-filter

/**
* Virtual method canProcessFile: determine whether hard processing is used
* to move the source file into the output directory, or whether a simple
* symlinking approach should be sufficient.
*
* By default, this method returns true if the extensions option is a
* non-empty list, and the relativePath ends with one of the extensions.
*
* The results of this operation are cached automatically, and it will not be
* invoked again for a given relative path.
*/

/**
* Virtual method getDestFilePath: optionally rename the output file when
* processing occurs.
*
* By default, if the options passed into the Filter constructor contains a
* property extensions, and targetExtension is supplied, the first matching
* extension in the list is replaced with the targetExtension option's value.
*
* The results of this operation are cached automatically, and it will not be
* invoked again for a given relative path.

* Abstract method processString: must be implemented on subclasses of

* The return value is written as the contents of the output file
