Automatically install public resources from Symfony2 bundles when a file changes

watch_assets.sh

#!/bin/bash

# Useful when you're making lots of changes in bundle/Resources/public and want
# to see the changes quickly in your browser.
# chmod +x the file then call the command like `./watch_assets.sh`
# Make sure you're in the project root directory (the one containing app, src etc)

if [ -z `which inotifywait` ] ; then
    echo "You must install inotify-tools to use watch_assets"
    exit 1
fi

function update_assets {
    php app/console assets:install web
    chmod 777 app/cache -R
    chown `logname`:www-data . -R
}

echo "Watching ./src/*/Resources/public... "
PUB_FILES=`find ./ -path ./src/*/Resources/public`

while inotifywait -re modify $PUB_FILES &>/dev/null ; do
    sleep 1
    echo -n "Change spotted! Installing assets... "
    update_assets &>/dev/null
    echo "done"
    if [ ! -z `which notify-send` ] ; then
        notify-send "Assets updated" "A change was detected & assets were updated"
    fi
done

I've added the update_assets function so this gist actually like, works and stuff.

Note that in the update_assets function you should do whatever you want. At least make sure login-name:www-data are the user & group the assets need to belong to with your dev setup.
