Command line one liner to find and open function definitions in Sublime Text 2

gistfile1.sh

# Alias ST2's command line tool for a shorter (easier-to-remember) name
alias st="/Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl"

# Search for an open Sublime Text to a function definition
function fx() {
	ack "function &?$1\(" | awk {'print $1'} | sed 's/:$//g' | xargs st
}

# Example usage from the root of a WordPress repository

# fx wp_remote_get

# Automatically opens wp-includes/http.php to line 74 in Sublime Text 2
# If the function is defined multiple times (e.g. methods of classes) it will open all of the files
# ...but only the last one will be on the correct line
