Git bisect is awesome! Awesome.
Most of you probably know it, but for anyone who doesn’t. this is a good tutorial.
A huge unwanted margin had appeared to the right of my container on mobile and tablet sizes.
Poked around in firebug for a bit unsuccessfully.
Find an old commit
$ git checkout [old_commit_hash] $ gulp
Reload browser. The margin’s gone! Make not of the
$ git checkout master
This step is important, 'cause at the end of bisect
reset takes you back to last checkout out commit.
$ git bisect start $ git bisect bad $ git bisect good [old_commit_hash]
Then git checks out a commit half way in between.
Reload browser. And either
$ git bisect good or
$ git bisect bad.
Git keeps going half way until there are no bisections left. Then use
gitk to look through the code changes introduced in that commit and find the error of your ignorant ways. Fix it.
$ gulp. Reload. Good!
$ git commit -am "fixed that pesky bla bla bla." $ git bisect reset
Now you are back on master with your updated code change. Awesome.
