[PATCH] Help scripts that use git-rev-parse to grok args with SP/TAB/LF
The git-rev-parse command uses LF to separate each argument it
parses, so its users at least need to set IFS to LF to be able
to handle filenames with embedded SPs and TABs. Some commands,
however, can take and do expect arguments with embedded LF,
notably, "-S" (pickaxe) of diff family, so even this workaround
does not work for them.
When --sq flag to git-rev-parse is given, instead of showing one
argument per line, it outputs arguments quoted for consumption
with "eval" by the caller, to remedy this situation.
As an example, this patch converts git-whatchanged to use this
new feature.

git's rev-parse.c function show_datestring presumes gnu date
Ok. This is the insane patch to do this.
It really isn't very careful, and the reason I call it "approxidate()"
will become obvious when you look at the code. It is very liberal in what
it accepts, to the point where sometimes the results may not make a whole
lot of sense.
It accepts "last week" as a date string, by virtue of "last" parsing as
the number 1, and it totally ignoring superfluous fluff like "ago", so
"last week" ends up being exactly the same thing as "1 week ago". Fine so
far.
It has strange side effects: "last december" will actually parse as "Dec
1", which actually _does_ turn out right, because it will then notice that
it's not December yet, so it will decide that you must be talking about a
date last year. So it actually gets it right, but it's kind of for the
"wrong" reasons.
It also accepts the numbers 1..10 in string format ("one" .. "ten"), so
you can do "ten weeks ago" or "ten hours ago" and it will do the right
thing.
But it will do some really strange thigns too: the string "this will last
forever", will not recognize anyting but "last", which is recognized as
"1", which since it doesn't understand anything else it will think is the
day of the month. So if you do
gitk --since="this will last forever"
the date will actually parse as the first day of the current month.
And it will parse the string "now" as "now", but only because it doesn't
understand it at all, and it makes everything relative to "now".
Similarly, it doesn't actually parse the "ago" or "from now", so "2 weeks
ago" is exactly the same as "2 weeks from now". It's the current date
minus 14 days.
But hey, it's probably better (and certainly faster) than depending on GNU
date. So now you can portably do things like
gitk --since="two weeks and three days ago"
git log --since="July 5"
git-whatchanged --since="10 hours ago"
git log --since="last october"
and it will actually do exactly what you thought it would do (I think). It
will count 17 days backwards, and it will do so even if you don't have GNU
date installed.
(I don't do "last monday" or similar yet, but I can extend it to that too
if people want).
It was kind of fun trying to write code that uses such totally relaxed
"understanding" of dates yet tries to get it right for the trivial cases.
The result should be mixed with a few strange preprocessor tricks, and be
submitted for the IOCCC ;)
Feel free to try it out, and see how many strange dates it gets right. Or
wrong.
And if you find some interesting (and valid - not "interesting" as in
"strange", but "interesting" as in "I'd be interested in actually doing
this) thing it gets wrong - usually by not understanding it and silently
just doing some strange things - please holler.
Now, as usual this certainly hasn't been getting a lot of testing. But my
code always works, no?

[PATCH] Help scripts that use git-rev-parse to grok args with SP/TAB/LF
The git-rev-parse command uses LF to separate each argument it
parses, so its users at least need to set IFS to LF to be able
to handle filenames with embedded SPs and TABs. Some commands,
however, can take and do expect arguments with embedded LF,
notably, "-S" (pickaxe) of diff family, so even this workaround
does not work for them.
When --sq flag to git-rev-parse is given, instead of showing one
argument per line, it outputs arguments quoted for consumption
with "eval" by the caller, to remedy this situation.
As an example, this patch converts git-whatchanged to use this
new feature.

Clean up work-tree handling
The old version of work-tree support was an unholy mess, barely readable,
and not to the point.
For example, why do you have to provide a worktree, when it is not used?
As in "git status". Now it works.
Another riddle was: if you can have work trees inside the git dir, why
are some programs complaining that they need a work tree?
IOW it is allowed to call
$ git --git-dir=../ --work-tree=. bla
when you really want to. In this case, you are both in the git directory
and in the working tree. So, programs have to actually test for the right
thing, namely if they are inside a working tree, and not if they are
inside a git directory.
Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was
specified, unless there is a repository in the current working directory.
It does now.
The logic to determine if a repository is bare, or has a work tree
(tertium non datur), is this:
--work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true,
which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR
ends in /.git, which overrides the directory in which .git/ was found.
In related news, a long standing bug was fixed: when in .git/bla/x.git/,
which is a bare repository, git formerly assumed ../.. to be the
appropriate git dir. This problem was reported by Shawn Pearce to have
caused much pain, where a colleague mistakenly ran "git init" in "/" a
long time ago, and bare repositories just would not work.
