#69 pacsearch producing strange warnings

[Kjartan Fredrik Kvamme]

Running pacsearch to search for a package returns lots of strange warnings in addition to the relevant output.

$ pacsearch wx
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LC_ALL = (unset),
        LANG = "en"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

The perl warnings at the beginning go away if I manually set LC_ALL=C by running
$ export LC_ALL=C

However, pacsearch still produces the other warnings.

This exact same issue happens on fresh installations of MSYS2 on both my work PC and my home PC.

I second that, getting the same output. I needed to re-install msys2 due to a silly mistake on my part. The old version was not impacted by this problem.

[Matthieu Vachon]

The latest commit modifying pacsearch.in broke it. The offending diff is can be seen here.

I will try to pin-point the problem but I never worked with Perl before.

Thanks, it would be great if you can research this. We use unstable pacman version from upstream. Will switch to stable after next release.

Fixed in latest pacman.
