less-watch

Node process to monitor changes to specified files or directories, and execute some specified action in response.

Settings are stored in ~/.less-watch

If some file does not exist, the script will continue to try the other files, and retry any inaccessible file every 60 seconds. I do a lot of development on remote servers, so the files are only accessible when I have sshfs connected, but I don't want to have to run something to tell my LESS compiler that it should retry the filepath in question.

(This particular feature is not actually in 0.0.2, by the way. It's planned.)

Installation

For Mac OS X:

# cd into this directory
touch ~/.less-watch
./install

This will add the LessWatch.app application to the list of applications in your "login items," so that it gets started automatically.

After running ./install, either restart your computer or double click LessWatch.app.

~/.less-watch format

Each line has a glob (or simple file) on the left of a colon, and a command on the right.

The command on the right will have the following keywords available:

  • {file}, the fullpath of the matching file (usually just the string to the left of the colon).
  • {basename}, the shortname of {file}, without path or extension.
  • {dirname}, the directory containing {file}.

~/.less-watch example

/Users/chbrown/work/mailmaster/static/css/site.less: cd {dirname} && lessc -C site.less site.css
/Volumes/sshfs_drive/app4/static/*.less: cd {dirname} && lessc -C {basename}.less {basename}.css
