I sometimes like do my development work in a local Mercurial repo even though I’m stuck checking into ClearCase in the end.
I create a fresh snapshot view in ClearCase, create a Mercurial repo on the view, then do my work in a clone of that Mercurial repo. It isn’t ideal, but it allows me to delay all the file checkin/checkout work required when dealing with ClearCase. The main advantage is that it frees me to use whatever IDE or text editor I want, without relying on an integrated ClearCase plugin.
The tricky part comes when it is time to push my changes from my clone to the hybrid Mercurial/ClearCase repository/snapshot view — or more accurately, after the push, during a hg update on the hybrid repo/view.
I’ve been using this bash script (run in Cygwin since ClearCase isn’t available for OS X) to help with that step.
It continuously attempts to update (via
hg update) the hybrid repo/view, and looks for files that need to be Checked Out in the ClearCase snapshot, and then checks them out.
