I actually think Phil's patch from today is a little cleaner for most of
these, as it returns the values via out-parameters, and uses the return
value for "did we get anything?".
True. That part of the interface is indeed better done with the new
one.
I am still in favor of this suggestion you earlier made:
So the final solution is more like:
- a formatter for just the reflog time, respecting date
- a formatter for just the reflog index (the "0" in HEAD@{0})
- a formatter for the ref name (just the "HEAD" in HEAD@{0})
though. After all we only need three short ones while we migrate
away to a longer %(reflog:<what>) format, right?
As to the unfortunate %gd that squats on the "date" other specifiers
use, I do not see a good/quick approach to migrate it. If our ideal
short-term endgame before the longer format were to use %gd, %g# and
%gg for the above three, we first start warning people who use %gd
for the historical mistaken "reflog selector", while telling people
to use "%gg@{%g#}" instead if they truly want "reflog selector", and
then switch its meaning to "reflog date". That would take a long
time.
As %r prefix is not taken, we can immediately deprecate %g-anything
format as a historical mistake and make sure we do not repeat the
mistake of giving "d" to "reflog selector", perhaps?
