git-spelunk

This is git-spelunk, an interactive tool for exploring blame history.

Install with gem install git_spelunk (requires Ruby 2+).

Huh?

git blame is a great tool for determining code responsibility. But sometimes when you fire up git-blame, you'll find yourself in a loop of git-blame, git-show, and then git-blame again in order to find the true owner of a line of code. git-spelunk is the tool for situations like this, when you want to skip past syntactic and refactoring commits to find the true owner of a line, or see how a piece of source code has evolved over time.

Guh?

It's easier to show you.

git spelunk lib/git_spelunk/offset.rb

git spelunk, main page

You can see we've highlighted line 45. git-spelunk here is telling us that this line was introduced in commit 33465d2. You can also see that all other lines that were involved in 33465d2 are picked out in green. The output of git show is present as well for adding more context to the information.

Now we press '['. What we're asking here is "show me the file just before 33465d2" was introduced, essentially replacing the content of the current screen with git blame [file] 33465d2~1.

git spelunk, back one

There's other stuff to do; you can hit "s" to do a git show of the commit underneath the cursor, you can search and page through the file like you would with "less".
