Cactus (http://cactusformac.com/) plugin that generates an external build folder that doesn't overwrite your git files. Perfect for usage with GitHub pages, just stick your .git in the generated build folder.

generate_build.py

import distutils.dir_util
import shutil
import os

def copytree(src, dst):
    for item in os.listdir(src):
        s, d = os.path.join(src, item), os.path.join(dst, item)
        if os.path.isdir(s):
            shutil.copytree(s, d, False, None)
        else:
            shutil.copy2(s, d)

def postBuild(site):
    build_folder = site._path + "/build"

    for sub_file in os.listdir(build_folder):
        if sub_file[0] != ".":
            sub_file_path = os.path.join(build_folder, sub_file)
            try:
                if os.path.isfile(sub_file_path):
                    os.unlink(sub_file_path)
                elif os.path.isdir(sub_file_path):
                    shutil.rmtree(sub_file_path)
            except Exception, e:
                print e

    copytree(site.build_path, build_folder)

@moomoohk Cactus for Mac ≠ Cactus.
The later is the static website generator that works via the command line and is used by Cactus for Mac.
The latest version of Cactus is v3.0.2, well according to the commit, its not yet in the releases.

Gotcha! Thanks.
