tig, the ncurses front-end to Git
This is a guest post from Nathan de Vries.
I’ve never really been a fan of gitk, but early on when I started using Git I found a tool called tig. It’s available in MacPorts and Ubuntu (since Gutsy) through apt-get install tig. Tig provides a simple command-line yet visual interface to Git.
The simplest usage is just running tig when you’re in a git repository. This will bring up visual git-log, but the nice thing about it is that you can navigate up and down the log using the up and down keys (or j and k keys if you’re used to vim keys). Hit <enter> on a log entry, and it will open a split-pane window with the diff of that commit. Using <space> will move you through the diff, and up and down will move you between commits. Hitting q will close the split-pane, and hitting q again will close tig altogether.
Another useful aspect of tig is the tree-view. When you launch tig, hit t when you’re in log view and it will bring up a navigatable tree view of the repository. Hit <enter> to descend into directories or view files, or <shift>-B on a file to see an annotated view.
So far we’ve just been using tig on whichever branch we have checked out at the time, but tig also takes a revision argument (i.e. branch, tag, hash etc.). I personally find this useful for seeing what’s going on in remote branches, by using a command like tig origin/rel-1.5.
Showing another branch from within a different branch can also be incredibly handy if you’d like to cherry-pick a change from another branch into the current branch. Say I’ve committed a change to master that I’d like to make available to the release branch origin/rel-1.5. All I need to do is checkout the release branch with git checkout -b 1.5 origin/rel-1.5, open tig using tig master, navigate to the changeset I’d like to cherry-pick, and hit <shift>-C. Repeat as necessary.
I haven’t really had a chance to investigate many of the other features of tig, other than tig show [rev] and tig blame [file] which I use every day. If anyone has some more tips as to how to make good use of tig, be sure to share them in the comments!
