At my $dayjob, when we switched from cvs to git, I got _lots_ of
support questions around people being confused with merges and rebases
-- they often didn't realize they were still in the middle of one, or
didn't know how to resolve conflicts, or didn't know how to complete
the operation (i.e. didn't know that they needed to "commit" or
"rebase --continue"), or didn't know how to abort the operation. This
despite a few hours of dedicated training on basic git usage for
everyone including some nice handouts. [Granted, most developers were
engineers that were more interested in engineering and physics than
"computer science stuff", didn't have a very strong grasp of version
control, plus they had years of brain damage from CVS usage to cope
with, so this user group may be uncommon -- at least other than the
CVS usage bit.] Fixing the bash prompt would help in reminding people
that they were in the middle of an operation, but not the other
issues. And most people were stubbornly sticking with tcsh as their
shell, preventing even using that solution.
Most such users were using EasyGit (lightweight git-like wrapper
designed to assist in avoiding common gotchas for those braindamaged
by CVS or SVN), so I quickly modified "eg status" to also print
annoying "YOU ARE IN THE MIDDLE OF A <OP> OPERATION. TYPE 'eg help
topic middle-of-<OP> FOR MORE INFO" notices when relevant[1].
After making that change, support questions dropped _dramatically_.
I'm a bit ashamed I never got around to making that into a proper RFC
patch for git (yet?). I'm not sure whether it'd fit git, but it's
certainly worth discussion and was amazing how much it helped us.
