Script to run watchr and compile LESS

less_watcher.sh

#!/bin/bash

# These are the original commands, courtesy of: 
# http://www.ravelrumba.com/blog/watch-compile-less-command-line/

# Requires watchr: https://github.com/mynyml/watchr
# watchr -e 'watch(".*\.less$") { |f| system("lessc #{f[0]} > #{f[0]}.css && echo \"#{f[0]} > #{f[0]}.css\" "}') }

# Requires inotify-tools: https://github.com/rvoicilas/inotify-tools
# while true;do N=`find -name "*.less" `;inotifywait -qe modify $N ;for f in $N;do lessc $f ${f%.*}.css;done;done

# I wanted to add something like this:
# ls *.less.css | awk -F. '{ print "mv "$1".less.css "$1 ".css" }' | bash

# I was having trouble mixing Bash and Ruby, so I settled on doing this:
# less_watcher:

watchr -e 'watch(".*\.less$") { |f| system("echo \"#{f[0]} > #{f[0]}.css\" && less_helper.sh #{f[0]}") }'

# less_helper.sh:

lessc $1 > $1.css
echo $1 | awk -F. '{ print "mv "$1".less.css "$1 ".css" }' | bash

# I guess I could've replaced the awk one-liner with a Ruby one liner,
# especially since my command now needs to be run within the directory it's
# watching. when I need to monitor multiple directories I'll change it.
