Checkout the Last Public Revision with Mercurial
I've always preferred git over Mercurial (
hg) because the feature branch workflow makes organizing code and working off of master very easy. You don't get that with vanilla mercurial -- instead, commits can just sort of apply on top of each other, without much organization. Sometimes mercurial can feel a bit chaotic.
When working on Mozilla's mozilla-central repository (for your beloved Firefox!), I always start new commits off of the latest public commit. "public means it has been merged into mozilla-central, "draft" means it was created locally and is only on my machine.
Getting the last public revision ID required a bit of command line hackery and search so I found a better way to check out the last public revision:
hg checkout -r 'last(public())'
That command is a bit much to remember so I created an alias in my
alias hgmaster='hg checkout -r “last(public())”’
