@deckyard/git

Git repositories for Jennifer through the git command line: open, create and clone repositories; status, staging, commits and stashes; log, diffs, blame and files at any revision; branches, tags and merges; fetch, pull and push. Results are typed structs parsed from git's machine-readable output. Built for names and URLs you do not control: option injection, remote helpers, repository-redirecting environment variables and hooks are all shut off, and every command has a timeout.

Documentation

Install

jvc add @deckyard/git

Or unpack src/ from a release archive (deckyard-git-<version>.tar.gz) into vendor/deckyard/git/.

Usage

import "@deckyard/git/" as git;

def repo as git.Repo init git.open(git.config(), ".");
def s as git.Status init git.status($repo);
io.printf("%s, %d changed\n", $s.branch, len($s.changes));
for (def c in git.log($repo, "", "", 5)) {
    io.printf("%s %s\n", strings.substring($c.hash, 0, 8), $c.subject);
}

Requirements

Jennifer 0.25.0 or newer and the default jennifer binary (the deck needs the exec capability); git 2.25 or newer and env on the PATH.

Development

tools/check-all.sh                   # the full gate, as CI runs it
jennifer test src/git_test.j         # tests; the live ones need git
tools/check-docs.sh                  # docs against the code

The tests that run git use throwaway repositories in the temp directory and no network. They return early where git is not installed, as in CI's container; run the suite on a machine with git before a release.
