Bug 830329 – x11-terms/rxvt-unicode-9.30: some bundled Perl plug-ins implicitly depend on USE=fading-colors

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Alex Efros 2021-12-31 00:11:12 UTC]

When built without USE-flag fading-colors it prints this error on start:

$ urxvt
urxvt: perl hook 0 evaluation error: /usr/lib64/urxvt/perl/background: Bareword "urxvt::Color_fade" not allowed while "strict subs" in use at /usr/lib64/urxvt/perl/background line 992, <$fh> line 1.

and all urxvt perl modules doesn't work.

This issue wasn't exist in 9.26-r2.

Any thoughts on this, Perl people? I've got no idea how exactly embedded Perl picks up X resources.

    x11-terms/rxvt-unicode: Perl support now requires USE=fading-colors
    
    This is probably a bug but one that will most likely require either an
    upstream reaction (which given their attitude towards Gentoo is
    unlikely to happen if reported by us) or a third-party patch.
    
    While at it, stop defaulting to USE=perl.

I don’t think this is true. It may break some plugins, but not all of them. I hacked the ebuild to allow building with USE="-fading-colors perl". I use “Rxvt.perl-ext-common: default,matcher”. No errors were printed and the plugins appear to work in that URLs are clickable and mouse-click highlighting works in the different way that I expect.

I agree, the "selection" plugin works without fading-colors here as well.

[Comment 5 Marek Szuba (RETIRED) 2022-06-07 08:48:00 UTC]

OK, so are there in fact ANY Perl plug-ins bundled with rxvt-unicode other than "background" that require --enable-fading?

[Comment 6 Tom Gillespie 2022-08-05 17:54:37 UTC]

Yes, the url matcher plugin requires fading-colors otherwise it won't work.
