Gogot

Git, but in Go

Inspired by this article by ThoughtBot titled "Rebuilding Git in Ruby", I made a similar program but in Go. Not really a full copy of Git, rather more like an attempt to understand how Git stores and manages file contents. The features supported (so far) are these:

• .gogotignore - Similar to .gitignore

• gogot init [PATH] - Similar to git init [PATH], it initializes a repo with a default main branch

• gogot add [PATH1] [PATH2] ... - Similar to git add .... Right now there's no support for gogot add -A|--all, but gogot add . does the trick

• gogot commit [MESSAGE] - Similar to git commit -m "[MESSAGE]"; gogot doesn't require quotes

• gogot log - Similar to git log --oneline; more condensed and quicker to write

• gogot time-machine [COMMIT-ID] [FILE-PATH]- I don't know the Git equivalent of this, but it prints the content of a given file in the specified commit

• gogot status - Similar to git status, showing different sections for not indexed files and for the files changed after indexed

• gogot branch [NEW-BRANCH-NAME] - Similar to git branch -m NEW-BRANCH-NAME

• gogot checkout [BRANCH] - Similar to Git's checkout for changing branches

• gogot rollback [COMMIT-ID] [FILE-PATH:optional] - I don't know the Git equivalent for this, but it should revert files (or just FILE-PATH, if it's present) as they were in COMMIT-ID.

Here's a sample run:

$ go build
$ ./gogot init kewl-projekt # You can also do `gogot init .`
Initalizing new Gogot repo
Gogot repo initialized in kewl-projekt/.gogot

$ cd kewl-projekt
$ touch hello.txt
$ ../gogot add .
$ ../gogot commit Initial commit

$ echo "Howdy y'all" >> hello.txt
$ ../gogot add .
$ ../gogot commit Greetings in hello.txt

$ echo "How's everyone doin'?" >> hello.txt
$ ../gogot add .
$ ../gogot commit Greetings extended...

$ ../gogot log
