This is a nice change, available because of lack of backward
compatibility with v1. The porcelain v2 format branch-related
information could be enhanced without risk of breaking parsers,
or having new information put at the end even if it does not fit
there (like in previous iteration).
One thing that can serve as goal for the series is using the
question: would it make __git_ps1() from git-prompt.sh be able
to render fully decorated prompt with all bells and whistles,
and with all combinations of options. Thus beside upstream
in the future we might want SVN upstream, and/or pushed-to
remote branch (and remote push upstream repository), etc.
But that's for the future (and it is possible for the future)...
Yes, I was hoping to be able to simplify and/or speed up
__git_ps1() with this data. "Namespacing" the branch data
here. And then later add the state data (in a merge,
in a rebase, and etc.) in a series of "# state.*" headers.
And so on, until we get everything that __git_ps1() needs.
However, to really make that work, we might want to add
a --no-scan (or minimial scan) option, to just return the
header data, since __git_ps1() doesn't care about the list
of changes.
But __git_ps1() with GIT_PS1_SHOWDIRTYSTATE would want to know
if there are unstaged and staged changes, and with
GIT_PS1_SHOWUNTRACKEDFILES it would want to know if there
are untracked (unknown) files, isn't it?
And GIT_PS1_SHOWSTASHSTATE would want to know if there is
something stashed, but I guess it is outside the remit of
git-status...
Also, __git_ps1() uses colors from git-status, so if it
is switched to use --porcelain=v2, then there should be an
option to turn the color on, isn't it?
All of these are good questions. But __git_ps1() is outside my
scope right now. All I was saying above is that by making
the branch details available here and, later, extending V2
output by adding other such headers to the output, we could
try to remove much of the business logic in __git_ps1() and
hopefully reduce it to just formatting and coloring the prompt
using the computed result from status.
But I've only skimmed __git_ps1() (and it's a little dense),
so I'd have to study it more before I could answer all of your
questions.
Thanks,
Jeff
