I don't generally use "git status -s", so I don't have a strong opinion,
but should this perhaps be optional?  I imagine people using it fall
into one of two categories:

  1. They want to waste less vertical screen real estate than "git
     status" does.

  2. They prefer to see files in a single list with status marked,
     rather than in separate lists based on status.

Your patch will probably annoy people in group (1) unless they have some
way to turn it off.

A few other comments on the patch itself:

> +	color_fprintf(s->fp, color(WT_STATUS_HEADER, s), "## ");

I thought the doubled '##' looked funny at first, but the more I look at
it, I think lining it up with the filenames looks good.

Style nits. This should be:

  if (!s->branch)
          return;

Why do we only mention it as an initial commit if there is no tracking?
We get if it is an initial commit and no tracking:

  ## Initial commit ... master

but if there is a tracking branch setup, we get no "Initial commit" at
all. And the use of "..." is confusing, as it usually implies symmetric
difference, which doesn't really make sense here.

> +}

Here we get:

  ## master (1) ... origin/master (1)

which kind of makes sense. The "..." implies symmetric difference. But
in other spots, like "git fetch" and "git push" output, we usually try
to make it cut-and-pastable in case one wants to view the actual
history. So maybe something like:

  ## master...origin/master [ahead 1, behind 1]

The latter matches how "git branch -v" prints it. I dunno. I guess this
is just bikeshedding really, so maybe others will chime in with
suggestions and you can pick the one you like best.

Hi jeff,

it's one line ;) but i can understand your concern. would `git status
-s -v` or `git status -s --show-branch` make sense?

i had one hash and two spaces at first, but as you said, two hashes
look more lined up.

i don't think it's (easily, without messing around with the .git
directory) possible to create a branch without commits that tracks
another branch (without commits). or is it?

i used ... to make it look consistent with normal branch output, but i
guess you are right. i changed it to `Initial commit on <branchname>

oh, i didn't know `git branch -v`. the cut&paste argument is really
strong, so i totally agree with you and changed my code.

branch names and ahead/behind numbers appear now in green and red to
match the output of `git branch -l`

here is the updated patch:

 - initial commit is also printed when there is tracking information
(i still haven't managed to create a situation like that. `git branch
oldmaster; rm .git/refs/heads/master; git branch master --set-upstream
oldmaster` will reset branch master to oldmaster (a bug?))
 - colors to match output of `git branch` (green: current, red: remote)
 - output format is copy-pasteable, ahead/behind information is in the
same format as in `git branch -v`
 - branch information is still printed by default, i have to look into
commandline option parsing first. i was thinking of `git status -v -b`
(as in `git checkout -b` to mean branch)

cheers, daniel

(i forgot to send my reply to the mailing list too …)

Re: [PATCH] Show branch information in short output of git status

[Knittl]

hi all,

here's the second part of the branch, so it will only show branch
information in `git status -s` if the additional option `-b` is given.

open for suggestions,
daniel

Subject: [PATCH 2/2] Hide branch information per default in short
output of status

Branch information remains hidden, unless the command line option `-b`
is given to `git status -s`. This way the command does not change from
older versions.

Also hide branch information in `--porcelain` output

Try:

  git branch oldmaster
  rm .git/refs/heads/master
  git config branch.master.remote .
  git config branch.master.merge refs/heads/oldmaster

That being said, I still get "Initial commit on master". I think that
stat_tracking_branch just gives up if the branch doesn't exist (which
does make some sense). So in practice, I think your original and this
one actually behave the same (sorry, I know that changing it was my
suggestion).

And no, the "--set-upstream" behavior is not a bug. At least not
according to the documentation. ;)

I think it's much nicer, though the colors are a bit much for my liking.
Still, it's configurable, so I don't have to care. :)

You may also want to have a configuration option if it is the output you
prefer all the time (similarly, if you are using "git status -s" all the
time, you might want a config option to make "git status" do what you
want).

This patch looks OK, but:

  1. I think for the final version you can just squash in part 2/2.

  2. Your patch has wrapped lines which make it impossible to apply
     without fixing up manually. This is a common gmail problem.  See
     the "gmail" section of SubmittingPatches.

yep, that's what i discovered too—but i don't care if this condition
is 3 lines up or down. if stat_tracking_branch decides it will work
for initial commits, then this code will do the expected thing

i find the numbers quicker to spot when they are a different color
from normal text, but if the majority objects i can remove them of
course.

on my local system i have `alias.st = git status -sb`, so i don't
really find a need to make a config option. actually i fall into both
groups you described in your first answer: having a quick glance what
files were changed and grouping files based on status. so i write both
`git st` and `git status` quite often (also with `git stat` my alias
for `git diff --stat` to see what changed content-wise)

should be no problem. the second patch changed quite a bit, so i
thought it is easier to review when i send it as a separate patch. the
final patch can be squashed of course

ok, browsed through that. i think i will just put my branch into a
pasteservice or on a fileserver, unless the email way is *really*
preferred—what about email attachments?

OK.  Nobody else seems to be commenting, so I would go ahead and put
together your final patch, cc-ing the maintainer.

Inline email is best, but I think an email attachment would be preferred
to putting it on some out-of-band service (it's nice for the mailing
list archive to have a record of everything).

Been following silently :)

I'm a regular shortstatus user and find myself calling ordinary status
just to get that part of info you're adding to shortstatus. I agree the
default should stay as is and use aliases anyways. (I also think we need
to clean up our option/config mess at one point and make at least long
options the same as config variables.)

I even wanted to try out the patch but was stopped by:

I'm really wondering what the problem is with git-send-email + GMail's
smtp. I'm not saying there is none: I'm just observing that we seem to
attract a lot of new contributors lately and that the email-inline-patch
requirement seems to be a hurdle to quite a few. I've created a mob
branch at

http://repo.or.cz/w/git/mjg.git

based off current master to which you can push, Daniel.

I'm wondering whether we should have a mob branch+receive hook solution
where people can push to mob-{maint,master,next} (whose tip coincides
with the resp. main branches), maybe allowing fast-forwards only, and
where a post-receive-hook hook sends the patch to the list and resets
the mob-... branch.

That would require push/pull expertise only, no MUA tweaking necessary.

Cheers,
Michael

I don't use gmail, but my impression was that the problem is one of:

  1. pushing to gmail's drafts folder via imap, and then using the web
     interface to send the email

  2. cutting and pasting into the web interface

I would hope that sending directly via SMTP with git-send-email would
not get munged. That is pretty broken otherwise.

Well, I know what the problem is with GMail's IMAP and web, but it's
good to have it summed up this concisely ;)

I'm wondering what the problem is with GMail's SMTP: Technically there
is none, but people shy away from using it (together with
git-send-email). It does not even require setting up an MTA like
sendmail or msmtp. But, apparently, this is a hurdle, which is why I
brought up the mob-auto-send.

[PATCH] Show branch information in short output of git status

[Michael J Gruber]

From: Daniel Knittl-Frank <knittl89+git@googlemail.com>

This patch adds a first line in the output of `git status -s` when given
the option `-b` or `--branch`, showing which branch the user is
currently on, and in case of tracking branches the number of commits on
each branch.

I tried it and I like it! [Ordinary status could use the same colors for
tracking info, they're helpful.]

I also like the fact that --porcelain -b does what it should (unchanged
by the patch).

I'm wondering what "git status -b" should do. Currently, "-b" is ignored
silently. One may argue it's okay since ordinary status shows tracking
info anyways.
