Hi all,
I'm trying to get the committer date printed in a custom fashion.
Using "%cI" gets me close:
$ git show --format="%cI | %an" master | head -n 1
2017-01-31T17:02:13-08:00 | Hilco Wijbenga
I would like to get rid of the "-08:00" bit at the end of the
timestamp. According to the "git show" manual I should be able to use
"%<(<N>[,trunc|ltrunc|mtrunc])" to drop that last part.
$ git show --format="%<(19,trunc)cI | %an" master | head -n 1
cI | Hilco Wijbenga
Mmm, it seems to be recognized as a valid "something" but it's not
working as I had expected. :-) I tried several other versions of this
but no luck. Clearly, I'm misunderstanding the format description. How
do I get "2017-01-31T17:02:13 | Hilco Wijbenga" to be output?
Cheers,
Hilco

Will this work for you?
$ git show -s --pretty='%cd | %an' --date=format:%FT%R:%S
2017-02-02T10:01:36 | G. Sylvie Davies
I have no idea how portable this might be. As "git help log" says:
--date=format:... feeds the format ... to your system
strftime. Use --date=format:%c to show the date in your system
locale’s preferred format. See the strftime manual for a complete list
of format placeholders.

Ah, that does indeed do exactly what I want. Thank you.

It should be fine for my purposes.
Any idea why "%<(19,trunc)cl" doesn't work? (Your solution solves my
original problem perfectly but I'd like to understand how I'm
misreading the spec.)

You're almost there. Just insert another '%' between "trunc)" and "cI".

You'll get an ellipsis at the end though.. (i.e. 02:13... | Hilco)

Thank you so much! This has been bugging me. :-) Rereading "git help
show", I guess it's implied I should do this but it very much wasn't
clear to me (obviously). I guess I'm too used to the "%19.19s" type of
approach. Maybe there should be some examples?

Indeed, that's not very nice. I suppose I can understand the reason
for it but it mostly defeats the purpose of "trunc", doesn't it?
Luckily, Sylvie's solution does exactly what I want.

It depends. When you truncate a commit subject line, you may want an
indicator that you're not seeing the whole line. For fixed fields like
dates when you expect every string to be truncated, then yes there's
not much point to show the ellipsis.
