gota: manage multiple git repos with sanity

This is a remake of the gita project with golang (ported from gita v0.16.8.2). The motivations are

• speed improvements
  • eliminate the slow Python startup time
  • concurrent status/command execution via goroutines
• ease of maintenance
  • single static binary, stdlib only

Display side-by-side status of multiple repos and delegate git commands/aliases from any working directory:

gota ls
gota fetch
gota ll
gota stat myrepo2
gota super myrepo1 commit -am 'add some cool feature'

Installation

1. clone the repo
2. make
3. run gota command

Compatibility

Config-compatible with python gita. Config root is $GOTA_PROJECT_HOME > $GITA_PROJECT_HOME > $XDG_CONFIG_HOME > ~/.config, using the gota/ subdir — or falling back to an existing gita/ subdir, so it picks up a python-gita setup as-is:

• repos.csv (path,name,type,flags), groups.csv (name:repos:path)
• <group>.context / auto.context
• color.csv, info.csv, layout.csv, symbols.csv
• cmds.json (custom delegated commands, shadow the built-in ones)

All sub-commands ported: add rm freeze clone rename flags color info ll context ls group super shell clear plus the delegated git commands from cmds.json (fetch pull push st ll lo br ...) with per-repo flags, allow_all, disable_async, and shell-mode semantics. Async execution runs detached from the tty; failed repos are re-run synchronously so credential prompts still work.

Deviations from python gita

Upstream bugs fixed rather than ported:

• clone -n -f (dry-run from file) printed a traceback upstream; prints the clone commands here.
• add -a crashed when the first given path was not a parent of a found repo; non-matching paths are skipped.
• sync re-run after a failed async command dropped per-repo flags upstream; kept here.
• group add -n <existing> without -p silently reset the group path; path now only changes when -p is given.
• delegated custom commands with "shell": true crashed on >1 repo upstream; run via sh -c here.
• group rm of the current context left a stray .context file; the context is removed instead.
• flags ll printed the python list repr (['-c', ...]); prints space-joined flags.

Behavior differences:

• -s/--shell on delegated commands is a plain boolean flag (upstream needed a throwaway value: --shell x).
• gota <cmd> -h per-sub-command help is minimal; shell completion (argcomplete) not ported.
• new repos found by add are processed in sorted path order (upstream: undefined set order).

Test
