Find the first file matching a given pattern in the current directory or the nearest ancestor directory.

Project description

# python-findup

## Introduction

Find the first path matching a given pattern in the current working directory (or a given directory) or the nearest ancestor directory. This project is (roughly) a python version of [node-findup-sync](https://github.com/cowboy/node-findup-sync).

Why? Applications, such as git, often use project configuration files found in the current directory or an ancestor directory. The findup modules allows an application author to easily find these files or directories.

## Installation

The best way to install is probably to use pip:

pip install findup

Or you can clone and install findup from github:

git clone https://github.com/todddeluca/python-findup.git cd python-findup python setup.py install

## Usage

pattern is combined with the current working directory or an ancestor directory and passed to glob.glob to see if the pattern matches. If it does, the first match is returned. Pattern can contain some shell wildcard characters, like ? and *. See the python glob module for more details.

findup.glob(pattern)

To find the root dir of a git repository, when the current working directory is somewhere within the repository:

os.path.dirname(findup.glob(‘.git’))

Or more robustly, handling the case where the cwd is not within a git repository:

path = findup.glob(‘.git’) git_root = None if path is None or os.path.dirname(path)
