How do I compile a directory full of less css files to css?

Question

I have a directory full of less css files. What is the best way to compile them to normal css? (for deployment)

Id like to run a command as follows:

Answer 1

I have written a hackish script that solves the problem:

#!/usr/bin/env python


#This is responsible for "compiling" less.css files to regular css files for production. It also minifies the css at the same time. 

#Usage: give it a start directory as the first parameter and an end directory as the second parameter. It will recursivly run the appropriate command for all css files in the first subdirectory.


import os
import sys
import re
if len(sys.argv) < 3:
    sys.exit('ERROR: Too many paths!! No less css compiled')
if len(sys.argv) > 3:
    sys.exit('ERROR: Not enough paths!! No less css compiled')

start_dir=os.path.join(os.getcwd(),sys.argv[1])
end_dir=os.path.join(os.getcwd(),sys.argv[2])
pattern=r'\.css$'
pattern=re.compile(pattern)

files_compiled=0

def copy_files(start, end, add=''):
    global files_compiled
    try:
      os.mkdir(end)
    except:
      pass
    for folder in get_immediate_subdirectories(start):
      copy_files(os.path.join(start,folder), os.path.join(end+folder), add+folder+'/')
    for less in os.listdir(start):
      if pattern.search(less):
        os.system('lessc -x %s > %s'%(start+less,end+less))
        print add+less
        files_compiled=files_compiled+1

def get_immediate_subdirectories(dir):
    return [name for name in os.listdir(dir)
            if os.path.isdir(os.path.join(dir, name))]

Ideally there is a better solution.
