copy and mutate files by extension
Freud watches directories and copies files between them. It allows you to modify the file information before rendering using callbacks attached to file extensions.
Err that's confusing, here:
var Freud =var freud =md =freudfreud
That will watch
/home/me/src for changes to files with the
When there is one, it will run the file contents through
md, our theoretical
Markdown processor, and change the extension to
.html before dumping the
mutated file into
/home/me/html. Of course the origin file is never modified
in any way.
Listen also accepts '*:before' and '*:after' to apply to all processed files. You can probably guess when they occur. If you add a listener with '*', it will be pushed onto the '*:before' stack. Listen also accepts an array of extensions to listen for, like:
The file object available within your listen statements is of structure:
name: "example.txt"stats: node fsStats objectdata: "the file contents"write: true
file.write property is set to
false and never reset to

Freud does not watch sub-directories. In order to effectively monitor multiple directories, you will need to construct multiple Freud objects.
Freud also accepts an optional third parameter of an options object. The options available are as follows:
monitorDotto watch for dotfile changes, default is
monitorSquiggleto watch for files with names ending with ~, such as are common for backups. Default is
ignoreCaseto not match case on event/listener matching. Default is
Freud will also emit certain events that may be useful, such as:
startedwhen the service begins watching.
stoppedwhen service is stopped (via
