Where can I find the source code of gitk?

Question

gitk seems to have very nice interface design and whatnot. I really want to explore its source code. So where can I find it?

By gitk, I mean the one to view the repository history of git.

Answer 1

When dealing with Open Source get it from the horses mouth - gitk is now part of the git distribution.

http://git-scm.com/download

git clone git://github.com/gitster/git.git

Answer 2

gitk lives in a subfolder of git's official repository.

It's written in wish/Tcl. Its folder (at time of writing) can be found at https://github.com/git/git/blob/master/gitk-git, mostly contained in a single file called gitk.

Answer 3

gitk is its own source code, since it is written in tcl and tcl is a scripting language. Just open /usr/bin/gitk with the text editor of your choice. It seems to be contained in a single file.
