A simple package to save a compressed directory

freezedry

A simple method to store a compressed copy of a code repository with customizable filtering of files.

Full Documentation | GitHub | PyPI

Do you ever wish you knew exactly which version of code you used when you made a figure, ran a job on a HPC cluster, or anything else? Freezedry is the solution!

With freezedry, you can easily save a compressed copy of an entire file directory that is designed to focus on code. Freezedry is a very simple package-- it only has one method you need to use (freezedry) that takes as input a path to a directory and a path to an output file, along with a few customizable optional input arguments.

What does freezedry include? Everything, if you don't specify. However, it's very easy to ignore:

• git related files (i.e. anything with the pattern .git in the file path)
• anything specified in a .gitignore file (thank you to Michael Herrmann) for the useful gitignore_parser package.
• anything else you want (including exact string matches and regular expressions).

Installation

It's on PyPI. If there's any issues, please raise one on this GitHub repo to let me know.

pip install freezedry

Usage

Suppose that /..dirs../GitHub/your_repo contains some code you've been working on. And say you use the code in your_repo to do some analyses that are saved to /..dirs../results. Then, the following block of code will save a copy of your repo to the /results directory, ignoring any .git related files and ignoring anything in your .gitignore.

from freezedry import freezedry
directory_path = '/..dirs../GitHub/your_repo'
output_path = '/..dirs../results'
freezedry(directory_path, 
          output_path=output_path, 
          ignore_git=True, 
          use_gitignore=True, 
          verbose=True)

In addition, you can specify which files to ignore in two other ways:

1. Direct match strings with extra_ignore. This is a list of strings, and if any string in the list is contained in a file, that file will be ignored. For example, if extra_ignore=['hi', 'world'] then '../hi/test.py' and '../myworld.py' will be ignored.

2. Regular expression strings with regexp_ignore. This is a list of strings used as regular expressions. The rules are similar to extra_ignore, except that it uses the re.search method to find matches.

Setting the .gitignore

If .gitignore is not provided, then freezedry will look for it (non-recursively) in directory_path. Alternatively, you can provide a .gitignore directly with the optional argument gitignore_path. Note that you always have to set use_gitignore=True regardless of whether you provided a gitignore_path.

For example:

from freezedry import freezedry
directory_path = '/..dirs../GitHub/your_repo'
output_path = '/..dirs../results'
gitignore_path = '/..dirs../GitHub/my_other_repo/.gitignore'
freezedry(directory_path, 
          output_path=output_path, 
          ignore_git=True, 
          use_gitignore=True, # if False, won't use gitignore_path even if provided!!! 
          gitignore_path=gitignore_path, 
          verbose=True)
