🌀 Devious

A file linker that allows you to version large or sensitive files under Git.

Instead of tracking the file itself, which can result in bloated and sluggish to sync repositories, Devious has Git track a metadata file containing a reference to a particular version of a file. This allows you to version large files under Git without tracking the file directly in your repository.

dvs also enables a clean abstraction to track files in git that you do not want to directly check in. For example, data with sensitive or proprietary information you do not want in the repo history directly. A2-Ai manages our scientific project work in git with github, however for security and compliance reasons we check in no source data to the git repository so the data will not ever touch github. In addition, regulations such as GDPR require the ability to expire data. This becomes complicated if the data itself is checked into the repository history. Using dvs allows us the ability to expire the data without rewriting the repo history.

📦 Installation

Linux (User)

This installs the latest version of Devious to ~/.local/bin and adds ~/.local/bin to your PATH in ~/.profile.

curl -o- https://raw.githubusercontent.com/A2-ai/devious/main/scripts/install_user.sh | bash

📚 Usage

Provide a storage location

Start by navigating to a Git repository for which you'd like to version large files. You can then initialize Devious by telling it where you want to store tracked files for the current repository. This directory should be accessible in a shared location to all future users of the repository.

dvs init <storage-path>

Adding files

Once Devious is intialized, you can start adding files.

dvs add <glob> <another-glob>

dvs add accepts one or more globs, each representing a file or set of files to be tracked. Ignores files outside of current git repository. For example, dvs add *.png subdir/*.csv will add all PNG files in the current directory and all CSV files in the subdir directory.

Updating files

If you want to update a file after changing it, you can run dvs add <glob> again. Devious will automatically update the file's reference and add the new version to the storage location.

Getting files

You can get file(s) by running

dvs get <glob> [another-glob]

dvs get works the same way as dvs add, using globs, but instead of adding files to the storage location, it will retrieve them and place them in the current directory.

Listing tracked files

You can list all tracked files and their statuses by running

dvs status

or status for a specific file with

dvs status <path>
