I wouldn't say that version control systems inherently have an undo. I
was really tripped up by CVS at because there was no "undo". If
I committed a patch or made a tag, it was there forever.
I immediately made mistakes-- I committed files I didn't want under
version control, and make tags with horrible names.
My solution for "undo" while I was learning was to nuke the CVS
repository for a project and start over. :) In CVS that's sort of scary,
because the server is this thing you are never supposed to need to
touch. It has it's communication protocol and seems a little magical.
Darcs is less intimidating by simply storing things in a plainly visible
This thread does suggest an idea about how we might organize "darcs
--help" better. I'm just thinking aloud here, but maybe it would be
useful to organize the commands according to how "safe" they are.
read only commands
dangerous commands (the ones that provide "undo").
That's certainly not the only useful categorization, and perhaps not the
best phrasing, but something to keep in mind.
