Adam's git configuration files and utilities

This is my collection of configuration files and utilities for git.

CONTENTS

Contents include:

Management of multiple concurrent branches

• git-mixdown - mix down multiple branches into a single working branch. Useful for testing a combination of bugfixes / features at once via a throw-away temporary working branch.
• git-mix - syntactic sugar for configuring git mixdown
• ggrbm - "Git Rebase Multiple", for automated rebasing of multiple branches as a single workflow.

See also git-explode for automatically separating a single git branch into a number of smaller branches which are textually independent.

Upstream branch status reporting / management

• git-upstream - obtain the upstream tracking branch (N.B. depends on git-head, git-root, and git-prefix)
• git-set-upstream - set the upstream tracking branch (N.B. depends on git-head and git-root)
• git-merged - show which branches are merged into upstream or the given commit-ish (N.B. depends on git-root and git-upstream)
• git-compare - compare two references to find out how far one is ahead/behind of the other
• git-compare-upstream - set the upstream tracking branch (N.B. depends on git-compare, git-head, and git-upstream, and hence also on git-root and and git-prefix)
• git-wip - returns true if the current repo has any work in progress, i.e. commits out of sync with upstream, or unmodified/untracked files
• git-rm-merged-orphan-branches - remove local branches which have been merged and are not in any other remote. Use with care!!
• git-icing - a tasty wrapper around git cherry which adds a splash of colour, and blacklisting of commits which should never be upstreamed.
• git-cherry-menu - an interactive wrapper around git icing and git notes which makes it easy to cherry-pick and/or blacklist non-upstreamed commits.
• git-rnotes - a wrapper around git notes which makes it easier to share notes to and from remote repositories
• git-deps - MOVED TO DEDICATED REPO automatically detect dependencies between commits
• git-tag-patchset - quick way of tagging patch sets as they get uploaded to Gerrit, to keep track of a review's history, e.g. git review && git tag-patchset.

History rewriting

• git-rewrite-author - rewrite the author for a range of commits
• git-rewrite-committer - rewrite the committer for a range of commits
• git-sed-range - run a sed script over every log message in a range of commits
• git-add-prefix - add a prefix string to every log message in a range of commits

Management of remotes

• git-url-rewrite - convenient interface for setting git URL rewrites via url.$url.insteadOf
• git-annex-clean-sync - a wrapper around git annex sync which avoids trying to touch ignored or unavailable remotes.

Automatic committing and syncing

• git-auto-commit - automatically commits files according to the autocommit git attribute. For example, if .gitattributes contains:

    *.org autocommit=min-age=+5m
  

  then any file ending in .org which is newly added (i.e. not in the index yet) or has unstaged changes, and whose last commit time and last mtime are both over 5 minutes, will be automatically staged and included in an automatic commit for this invocation of the commit. Files which have staged changes are assumed to be part of an unfinished manual commit process, and are therefore skipped.

• auto-commit-daemon - a wrapper around git-auto-commit to run it perodically. This can be configured as a per-user systemd service, e.g. by placing the following in ~/.config/systemd/user/auto-commit-my-repo.service:

    [Service]
    ExecStart=/bin/sh -c "/path/to/auto-commit-daemon /home/me/my/repo"
    Restart=always
    NoNewPrivileges=true
    SyslogIdentifier=auto-commit-my-repo
    Environment=SLEEP=1m
  
    [Install]
    WantedBy=default.target
  

• auto-sync-daemon - a wrapper around git-annex-clean-sync which runs it whenever master or synced/master or synced/git-annex are updated. When run across a network of remotes, it will keep the master branch in sync across all of them. Works well in combination with setting receive.denyCurrentBranch to updateInstead, and using git-safe-push-to-checkout (see below) as the push-to-checkout hook.

• git-safe-push-to-checkout - a smarter push-to-checkout hook for when receive.denyCurrentBranch is set to updateInstead. It's near-identical to git's default behaviour when no push-to-checkout hook is provided; however it additionally bails if we have emacs lockfiles indicating edits in progress for files which would be changed by the push-to-checkout. This means that push-to-checkout works more safely and doesn't rewrite files which are currently being edited in emacs with unsaved changes. It can be installed via:

    ln -s `which git-safe-push-to-checkout` $my_repo/.git/hooks/push-to-checkout
  

Mapping files/blobs back to commits

• git-ls-dir - list files in a git repo tree together with the commits which most recently touched them (see a screenshot)

• git-find-blob - find which commits contain a given (non-abbreviated) blob

Sanity-checking submodule references

• git-find-missing-submodule-commits - find dangling references to submodule commits

Helper scripts

Little shell wrappers to make the git porcelain and higher-level scripts a little more beautiful.

• git-head - obtain the current branch
• git-root - obtain the absolute path to the root (top-level) directory of the repository we're currently in
• git-prefix - obtain the current directory path relative to the root (top-level) directory of the repository
• git-cdup - obtain the relative path from the current directory to the root (top-level) directory of the repository
• gfind - like find(1), but only lists files tracked by git

Shorthand wrappers

• gg* - a whole bunch of wrappers around standard git commands to reduce the number of keystrokes required and add a little bit of polish to the interface here and there.

... and more!

Feel free to browse the bin/ directory :-)

INSTALLATION

This repository is designed to be stowed directly into your home directory:

git clone git://github.com/aspiers/git-config.git
stow -d . -t ~ git-config

However if you only want to cherry-pick bits and pieces then you can easily just copy or symlink them in manually. Just be aware that some of the files depend on other files, some of which are in this repository, some of which are in other repositories such as https://github.com/aspiers/shell-env.
