Usage

Usage: samosa [OPTIONS] COMMAND [ARGS]...

  Enforce a triangular Git workflow. If this is not possible, explain why.

Options:
  --help  Show this message and exit.

Commands:
  add       Add URL as a remote repository named REMOTE.
  branches  List branches with details.
  clone     Clone remote URL as a local repository.
  commit    Commit changes with a sign-off MESSAGE.
  diff      Compare with upstream.
  fetch     Fetch all remote updates without changing local files.
  force     Force-push changes to a remote branch.
  graph     Show a detailed commit graph.
  init      Initialize an empty local repository.
  log       Show a streamlined commit log.
  pull      Pull changes from the default remote branch.
  push      Push changes to the default remote branch.
  set       Set KEY to VALUE in the local Git configuration.
  status    Inspect and repair local repository.
  switch    Switch to a new or existing BRANCH.
  tags      List tags with messages.

Samosa will always prepare a repository before attempting a command. If all checks pass, the command is executed. Otherwise, Samosa will make a suggestion and terminate with exit code 1 (error).

Samosa standard

The following checks should be true:

• In a Git repository
• There is a remote named "origin"
• There is a remote named "upstream"
• Author name and email are set, and are not invalid
• The default push target is "origin:current"
• The pre-commit hook exists and is executable
• There is a local branch named "main" (assuming init.defaultBranch is "main")
• The main branch tracks "upstream/main"
• Tags are sorted in descending order

See WORKFLOW.md for a detailed workflow that results in a samosa standard repository.

Suggestions

If you aren't forking, make origin and upstream equal

Forking a project may not be practical. In this case, set upstream and origin to the same URL.

(Forks may be disallowed for confidential projects. Forking may not be useful for solo maintainers.)

Out of scope

• Detecting/supporting other workflows.
• Oh sh*, git!
• Non-Python packaging. Requires:
  • Both git and libgit2
  • For development (Debian): build-essentials, python3-dev, libffi-dev, libgit2-dev

Development environment

Install prerequisites

• Python 3.12 (including python3-dev)
• pdm
• make
• pipx (optional, required for make install-source)

Instructions

• Fork the upstream repository.
• git clone [fork-url]
• cd [project-folder]
• Run make develop to initialize your development environment.

You can use any text editor or IDE that supports virtualenv / pdm. See the Makefile for toolchain details.

Please make test and make lint before submitting changes.
