For now simply add a few common aliases.

  co = checkout
  ci = commit
  rb = rebase
  st = status

Are these the best definitions of those shortcuts? It seems[1] that some
people define "ci" as "commit -a", and some people define "st" as
"status -s" or even "status -sb".

I feel bad about having waited for 4 rounds of this patch to say this,
but the basic change (providing "co", "ci", etc. as aliases by
default) does not look well thought through.

To you.

It would be a different story if this were a patch to update
documentation to suggest adding such aliases at the same time as
telling Git what your name is.  The user manual doesn't explain how to
set up aliases at all yet, and that should be fixed.

That's a completely different subject.

But making 'ci' a synonym of another command by default while still
keeping its definition configurable would be doing people a
disservice, I fear.

And I and many (most) users disagree.

As long as 'ci' works out of the box, it will
start showing up in examples and used in suggestions over IRC, etc,
which is great.

It might, or...

Unfortunately that means that anyone who has 'ci'
defined to mean something different can no longer use those examples,
that advice from IRC, and so on.  So in the world where 'ci' is a
synonym for 'commit' by default, while people still *can* redefine
'ci' to include whatever options they like (e.g., "-a"), actually
carrying out such a personal customization is asking for trouble.

Precisely for this reason it might not. If people know aliases can be
different in different machines, they would avoid them in
documentation which is meant for all machines.

If you truly want to be pedantic, you could add a warning if the
default alias is not used, and this warning gets silenced if the user
configures the alias manually.

Incidentally, that is also the reason git already doesn't allow
aliases to override built-in commands such as "git commit", even
though it would be convenient to some to not have to remember to add
"-a" each time.  As consolation we have been able to say "But you can
take the even shorter-and-sweeter 'git ci' and make it mean whatever
you want".  Now we should take that avenue away for people?

Who is taking away that avenue? Certainly not this patch.

Bad idea.

Only if you assume your hypothesis is a fact, which is not, and even
if you do, it's still not.

Hope that helps,

The project? No, it doesn't. Virtually every VCS out there has default aliases,
and Git somehow cannot manage to get them done.

And BTW, look what I can do in mercurial:

.hgrc
---
[alias]
status = status --all
---

OMG! The world is going to end! No, it's not, it's no problem. What you think
is so clearly a bad idea, seems to be doing just fine in Mercurial.
