I'm trying to write very small, modular code as functions to break up a big monolithic script that does a file system search for particular strings. The script works well, but it's not easy to maintain or add features to.
I'd like to have a function that builds a list of files with os.walk() and then have other functions accept that list as a parameter and modify it as needed. For example, if the user has specified that certain files and folders be excluded from the walk, I'd like to have functions like this:
def build_list(path): fs_list = os.walk(path) return fs_list
def skip_files(fs_list): remove files return fs_list
def skip_dirs(fs_list): remove dirs return fs_list
def search(fs_list): pass
The problem I'm encountering is passing the list to other functions.
err...
search(skip_files(skip_dirs(build_list(path)))) ?
What's your problem *exactly* ?-)
BTW, you may want to have a look at the path module : http://www.jorendorff.com/articles/python/path/
