Gita: a command-line tool to manage multiple git repos

This tool does two things

display the status of multiple git repos such as branch, modification, commit message side by side
delegate git commands/aliases from any working directory

If several repos compile together, it helps to see their status together too. I also hate to change directories to execute git commands.

Here the branch color distinguishes 5 situations between local and remote branches:

white: local has no remote
green: local is the same as remote
red: local has diverged from remote
purple: local is ahead of remote (good for push)
yellow: local is behind remote (good for merge)

The choice of purple for ahead and yellow for behind is motivated by blueshift and redshift, using green as baseline.

The additional status symbols denote

+: staged changes
*: unstaged changes
_: untracked files/folders

The bookkeeping sub-commands are

gita add <repo-path(s)>: add repo(s) to gita
gita rm <repo-name(s)>: remove repo(s) from gita (won't remove files from disk)
gita group: show grouping of the repos
gita group <repo-name(s)>: group repos
gita ungroup <repo-name(s)>: remove grouping for repos
gita ll: display the status of all repos
gita ll <group-name>: display the status of repos in a group
gita ls: display the names of all repos
gita ls <repo-name>: display the absolute path of one repo
gita rename <repo-name> <new-name>: rename a repo
gita info: display the used and unused information items
gita -v: display gita version

Repo paths are saved in $XDG_CONFIG_HOME/gita/repo_path (most likely ~/.config/gita/repo_path).

The delegating sub-commands are of two formats

gita <sub-command> [repo-name(s) or group-name(s)]: optional repo or group input, and no input means all repos.
gita <sub-command> <repo-name(s) or groups-name(s)>: required repo name(s) or group name(s) input

By default, only fetch and pull take optional input.

If more than one repos are specified, the git command will run asynchronously, with the exception of log, difftool and mergetool, which require non-trivial user input.

Customization

Custom delegating sub-commands can be defined in $XDG_CONFIG_HOME/gita/cmds.yml (most likely ~/.config/gita/cmds.yml). And they shadow the default ones if name collisions exist.

Default delegating sub-commands are defined in cmds.yml. For example, gita stat <repo-name(s)> is registered as

stat:
  cmd: diff --stat
  help: show edit statistics

which executes git diff --stat.

If the delegated git command is a single word, the cmd tag can be omitted. See push for an example. To disable asynchronous execution, set the disable_async tag to be true. See difftool for an example.

If you want a custom command to behave like gita fetch, i.e., to apply command to all repos if nothing is specified, set the allow_all option to be true. For example, the following snippet creates a new command gita comaster [repo-name(s)] with optional repo name input.

comaster:
  cmd: checkout master
  allow_all: true
  help: checkout the master branch

Another customization is the information items displayed by gita ll. The used and unused information items are shown with gita info and one can create $XDG_CONFIG_HOME/gita/info.yml to customize it. For example, the default information items setting corresponds to

- branch
- commit_msg

To create your own information items, define a dictionary called extra_info_items in $XDG_CONFIG_HOME/gita/extra_repo_info.py. It should map strings to functions, where the strings are the information item names and the functions take repo path as input. A trivial example is shown below.

def get_delim(path: str) -> str:
    return '|'

extra_info_items = {'delim': get_delim}

If it works, you will see these extra items in the 'Unused' section of the gita info output. To use them, edit $XDG_CONFIG_HOME/gita/extra_repo_info.py.

Superman mode

The superman mode delegates any git command/alias. Usage:

gita super [repo-name(s) or group-name(s)] <any-git-command-with-or-without-options>

Here repo-name(s) or group-name(s) are optional, and their absence means all repos. For example,

gita super checkout master puts all repos on the master branch
gita super frontend-repo backend-repo commit -am 'implement a new feature' executes git commit -am 'implement a new feature' for frontend-repo and backend-repo

Requirements

Gita requires Python 3.6 or higher, due to the use of f-string and asyncio module.

Under the hood, gita uses subprocess to run git commands/aliases. Thus the installed git version may matter. I have git 1.8.3.1, 2.17.2, and 2.20.1 on my machines, and their results agree.

Installation

To install the latest version, run

pip3 install -U gita

If development mode is preferred, download the source code and run

pip3 install -e <gita-source-folder>

In either case, calling gita in terminal may not work, then you can put the following line in the .bashrc file.

alias gita="python3 -m gita"

Windows users may need to enable the ANSI escape sequence in terminal, otherwise the branch color won't work. See this stackoverflow post for details.
