#
# Simple applescript browser reloader for Google Chrome. It will either open a 
# new tab with the url passed in as an argument or refresh an existing tab. 
#
# Link this up with watchr to auto-refresh browser windows when you save files
# or bind it in vim, textmate etc.
#
# example install:
#
# [nik@nikcub ~] $ echo $PATH
# /Users/nik/bin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
# [nik@nikcub ~] $ cd ~/bin/
# [nik@nikcub ~/bin] $ ln -s ~/Projects/applescript/chrome-refresh.sh cr
# [nik@nikcub ~/bin] $ cr localhost:3333/admin/posts
# 13:53:35 Opening http://localhost:3333/admin/posts
#
# link to watchr:
#
# [nik@nikcub ~/bin] $ watchr -e "watch( '\w+/.*\.py' ) { system('cr localhost:3333') }"
# (edit a file and save..)
# 14:00:23 Opening http://localhost:3333
#
# watchr is easy to install:
#
# [nik@nikcub ~] $ sudo gem install watchr
#

tell application "Google Chrome Canary"
	activate
	set theUrl to "${URL}"
	
	if (count every window) = 0 then

	set found to false
	set theTabIndex to -1
	repeat with theWindow in every window
		set theTabIndex to 0
		repeat with theTab in every tab of theWindow
			set theTabIndex to theTabIndex + 1
			if theTab's URL = theUrl then
				set found to true
				exit
			end if
		end repeat
		
		if found then
			exit repeat
		end if
	end repeat
	
	if found then
		tell theTab to reload
		set theWindow's active tab index to theTabIndex
		set index of theWindow to 1
	else
		tell window 1 to make new tab with properties {URL:theUrl}
	end if
end tell

you can use

if theTab's URL starts with theUrl then
if you only want to specify the host and don't want to set the path.

For those using Grunt, you can run this script with the grunt module grunt-exec (https://github.com/jharding/grunt-exec).

I put the script in the same folder where the Gruntfile.js is located and used the following configuration:

exec: {
  reload: {
    command: './reload.sh <%= conf.host %>',
    stdout: true,
    stderr: true
  }
}

If you want your editor to stay the active window, you might want to remove line 52 activate.
