[PATCH v2 4/6] built-ins: "properly" align continued usage output

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Let's "fix" various "git <cmd> -h" output by "properly" aligning the
output in cases where we continue usage output after a "\n". The "fix"
and "properly" scare quotes are because this actually makes things
worse in some cases, because e.g. in the case of "git tag -h" the
"\t\t" effectively works around how parse-options.c aligns this
output.

But two wrongs don't make a right, let's "fix" this by making it worse
temporarily, in anticipation of improving parse-options.c to handle
this alignment.

The issue is that we should have whitespace corresponding to the
length of the command name here, e.g. in the case of "git ls-remote"
it should be 14 characters, or the length of ""git ls-remote
". Instead we had 21 characters in builtin/ls-remote.c, those extra 7
characters are the length of "usage: " (and also " or:"). So in the C
locale the resulting output aligns nicely:

    $ git ls-remote -h
    usage: git ls-remote [--heads] [--tags] [--refs] [--upload-pack=<exec>]
                         [-q | --quiet] [--exit-code] [--get-url]
                         [--symref] [<repository> [<refs>...]]

But that's fragile, we might not be under the C locale. We really
should have parse-options.c itself add this padding. In a subsequent
commit I'll make it do that.

In the case of "tag" and "show-branch" and "stash save" the output was
not properly aligned, although in the "git tag" case it was
near-enough (aligned with the "-" in "git tag -l") to look good,
assuming C locale & a tab-width of 8. In any case, let's align this in
a way that looks obviously correct when looking at the source itself,
and then improve parse-options.c itself.
