A Python script to generate a Twig template file for a folder full of images. I use this so that my CSS can use the notation url('ing/name.png') and this does not get rewritten to url('../../Resources/public/img/name.png') I want all my image asset files to be relative to my web path, but I want to keep them located in my bundles

assets.py

#!/usr/bin/env python

import os
import argparse

parser = argparse.ArgumentParser(description='Create Assetic Twig image file list')
parser.add_argument('-b','--bundle', help='Bundle name', required=True)
parser.add_argument('-f','--folder', help='Image folder')
parser.add_argument('-s','--search', help='The location to recursively search & list')

args = vars(parser.parse_args())

# Default to "images"
if not args['folder']:
    args['folder'] = 'images'

if not args['search']:
    args['search'] = os.getcwd()

assetic = """
{%% image
    '@%(bundle)s/Resources/public/%(folder)s/%(name)s'
    output='%(folder)s/%(name)s' %%}
{%% endimage %%}"""


for root, dirs, files in os.walk(args['search']):
   for filename in files:
    # Exclude dotfiles, such as .DS_Store
    if not filename.startswith("."):
        print assetic % {'name': os.path.join( root[len(os.getcwd()):], filename ).strip("/"),
                        'bundle': args['bundle'],
                        'folder': args['folder']}
