These scripts automate various Git tasks.

Also see https://github.com/plume-lib/manage-git-branches and https://github.com/plume-lib/plume-scripts.

Installation

To install, run the following (or put it at the top of a script). Then, the scripts are available at /tmp/$USER/git-scripts.

if [ -d /tmp/$USER/git-scripts ] ; then
  git -C /tmp/$USER/git-scripts pull -q > /dev/null 2>&1
else
  mkdir -p /tmp/$USER && git -C /tmp/$USER clone --depth 1 -q https://github.com/plume-lib/git-scripts.git
fi

If you want to use a specific version of git-scripts rather than the bleeding-edge HEAD, you can run git checkout _SHA_ after the git clone command.

Most of the scripts use sh or bash, but some of the scripts use python.

Git version control scripts

ediff-merge-script

A script for use as a git mergetool; runs Emacs ediff as the mergetool. Documentation at top of file.

git-authors

Lists all the authors of commits in a git repository. Documentation at top of file.

git-clone-or-pull

Either clones a repository, or pulls it if it is already cloned. Documentation at top of file.

git-clone-related

Clones a repository related to the one where this script is called, trying to match the fork and branch. Works for Azure Pipelines, CircleCI, GitHub Actions, and Travis CI. Documentation at top of file.

Suppose you have two related Git repositories:
MY-ORG/MY-REPO
MY-ORG/MY-OTHER-REPO

In a CI job that is testing branch BR in fork F of MY-REPO, you would like to use fork F of MY-OTHER-REPO if it exists, and you would like to use branch BR if it exists. Here is how to accomplish that:

if [ -d "/tmp/$USER/git-scripts" ] ; then
  git -C /tmp/$USER/git-scripts pull -q > /dev/null 2>&1
else
  mkdir -p /tmp/$USER && git -C /tmp/$USER clone --depth 1 -q https://github.com/plume-lib/git-scripts.git
fi

git-find-fork

Finds a fork of a GitHub repository, or returns the upstream repository if the fork does not exist. Documentation at top of file.

git-find-branch

Tests whether a branch exists in a Git repository; prints the branch, or prints "master" if the branch does not exist. Documentation at top of file.

resolve-adjacent-conflicts

Edits files in place to resolve git conflicts that arise from edits to adjacent lines. Documentation at top of file.

resolve-blank-lines

Edits files in place to resolve git conflicts that arise from differences in blank lines and whitespace. Documentation at top of file.
