Project Description

Features

Formic is a Python implementation of Apache Ant FileSet and Globs including the directory wildcard **.

FileSet provides a terse way of specifying a set of files without having to enumerate individual files. It:

  1. Includes files from one or more Ant Globs, then
  2. Optionally excludes files matching further Ant Globs.

Ant Globs are a superset of ordinary file system globs. The key differences:

  • They match whole paths, eg /root/myapp/*.py
  • ** matches any directory or directories, eg /root/**/*.py matches /root/one/two/my.py
  • You can match the topmost directory or directories, eg /root/**, or
  • The parent directory of the file, eg **/parent/*.py, or
  • Any parent directory, eg **/test/**/*.py

This approach is the de-facto standard in several other languages and tools, including Apache Ant and Maven, Ruby (Dir) and Perforce (…).

Python has built-in support for simple globs in fnmatcher and glob, but Formic:

  • Can recursively scan subdirectories
  • Matches arbitrary directories in the path (eg /1/**/2/**/3/**/*.py).
  • Has a high level interface:
    • Specify one or more globs to find files
    • Globs can be used to exclude files
    • Ant, and Formic, has a set of default excludes. These are files and directories that, by default, are automatically excluded from all searches. The majority of these are files and directories related to VCS (eg .svn directories). Formic adds __pycache__.
    • Iterate through all matches in the sub-tree
  • Is more efficient with many common patterns; it runs relatively faster on large directory trees with large numbers of files.

Quickstart

Formic can be installed from the Cheeseshop with easy_install or pip:

$ easy_install formic

Once installed, you can use Formic either from the command line:

$ formic -i "*.py" -e "__init__.py" "**/*test*/" "test_*"

This will search for files all Python files under the current directory excluding all __init__.py files, any file in directories whose name contains the word ‘test’, and any files that start test_.

Or integrated right into your Python 2.7 project:

import formic
fileset = formic.FileSet(include="**.py",
                         exclude=["**/*test*/**", "test_*"]
                         )

for file_name in fileset:
    # Do something with file_name
    ...

That’s about it :)
