Building with default makepkg CFLAGS (including -pedantic and -Werror) produces the following build warning (warnings treated as errors):

expac.c: In function ‘format_optdep’:
expac.c:143:11: error: ignoring return value of ‘asprintf’, declared with attribute warn_unused_result [-Werror=unused-result]
asprintf(&out, "%s: %s", optdep->name, optdep->desc);
^
cc1: all warnings being treated as errors
make: *** [expac] Error 1

yep, its a bug. fixed.

'expac "%n %P" -Q' spits some garbage (weird characters) along with the info I requested:

...
xvidcore
xz ؚ Õ
youtube-dl
zathura
zlib
[karol@black ~]$ ?1;2c^[[?1;2c^[[?1;2c

or e.g.

...
xvidcore
xz * Ø* +%
youtube-dl
zathura
zlib
[karol@black ~]$ ?1;2c^[[?1;2c^[[?1;2c


As you can see, the garbage characters change from one run to another. The errors are present also for other packages, the above is just an example. perl is super-weird (it has a ton of provides):

Did I do something wrong? Can you reproduce it (I'm on 32-bit Arch)? If you want the full output, tell me how you should I sent it to you - e-mail?

Is there a way to tell expac to use another config file, instead of pacman.conf?

I see that different flags behave in different ways e.g.
%l install date (only with -Q)

doesn't return anything with '-S', but
%k download size (only with -S)

shows 0.00 KiB for every package when called with '-Q'.


I'm not sure if it's worth messing with the code, I think adding '(only with -Q)' to the man page is enough.
Thanks :-)

There's a bunch of flags which don't make sense with -S or -Q. In these cases, you can't trust the value they return. I suppose I could parse the format string and whitelist. Either way, you're right that I should document %w as being -Q only in the manpage.

Shouldn't 'install reason' be only available with -Q? With '-S' I'm getting 'explicit' for every package.

OK, thanks.

if [[ -d $_gitname ]] ; then
cd $_gitname && git pull origin pacman4
msg "The local files are updated."
else
git clone -b pacman4 $_gitroot $_gitname
fi

This way expac seems to be working with pacman4, but I'm curious if that's how you do it git-wise and PKGBUILD-wise.
