[gentoo-dev] New global USE flag: modplug

I'd like to add USE modplug to use.desc. I'll do it tomorrow,
unless someone objects.

Do those packages use the modplug flag to enable libmodplug support in
lieu of (or in addition to) some other means of playing MOD files, or does
the use flag enable/disable reading of MOD files entirely? If the latter
is the case, maybe just "mod" might be a better flag.

spooky; i was just looking at this particular USE flag today when i
recompiled audacious to get support for the .MODs i'm starting to
compose. i like the idea of modplug as a global flag. :)

If the flag enables mod support, it should be "mod" with the description 
saying that it enables mod support, the "how" of it probably doesn't 
particularly matter to the user reading about it.  If there's support for 
mod other than modplug, then "modplug" it should remain, and the 
description should mention that.  (See the recent discussion over 
USE=lame, vs. simply mp3, also a USE flag.)

Remember that tomorrow is always too soon in projects like Gentoo. :)

$ euses -s mod fmod modplug
media-video/vlc:mod - Enables Mod demux support.
games-strategy/dark-oberon:fmod - Add sound support (fmod)
media-libs/panda3d:fmod - Enables support for using mod files for audio
support gnustep-apps/cynthiune:modplug - Build with modplug support
media-libs/xine-lib:modplug - Build with modplug support
media-plugins/audacious-plugins:modplug - Build with modplug support
media-sound/audacious:modplug - Build with modplug support
media-sound/bmpx:modplug - Build with modplug support
media-sound/cmus:modplug - Build with modplug support
media-sound/herrie:modplug - Build with modplug support
media-sound/moc:modplug - Add support for modplug

That's three USE flags describing the same support for (playing) mod
files, but ebuilds depend on either media-libs/{fmod,libmodplug} and
the former has its own USE flag.

media-video/vlc has a libmodplug dependency and should probably be
changed to use IUSE=modplug instead of IUSE=mod, if USE=modplug goes
global.

Another prime example for use flags with more than two values:

mod=off
mod=fmod
mod=libmodplug

the first for disabling mod support, the second for enabling it and preferring
fmod implementation, the third for enabling it and preferring libmodplug
implementation.

I don't think you've actually argued the case why one USE flag with
three, perhaps four modes (off, fmod, libmodplug, and perhaps default)
is preferable to two USE flags with two modes each (fmod and modplug,
both refering to the libs a package links to, either on or off).

Besides, could you explain why are you trying to hijack a short and
simple thread about globalising one or two USE flags?

I'd rather not pull fmod and modplug into same flag mod because
fmod is a propietary junk (if you just look at the fmod ebuilds you'll
know..)

I tried to explain this before. See
<http://article.gmane.org/gmane.linux.gentoo.devel/52316/match=use+options>.

Having an ordinary use flag for each library may work well enough when there
are less than three libraries that provide a certain functionality, although
with 2 old-style use flags you already have one bogus fourth option. Default
should not be an option of its own; one of the three options should be the
default.

> Besides, could you explain why are you trying to hijack a short and

I'm not trying to hijack this thread. I'm just injecting one message pointing
this out as something I think could benefit from my proposal.

A few real examples may go a long way to explaining something.
