[gentoo-dev] [RFC] New global USE flag: sndio

[gentoo-dev] [RFC] New global USE flag: sndio

[Filip Kobierski]

Hello everyone,

after successfully proposing making io-uring global I will propose
another global USE flag: sndio.

As of right how 19 packages would use it[1] and only two of them
(waybar & scrummvm) provide details on what it provides exactly.

I think the generic descroption like
"Enable support for the <pkg>media-sound/sndio</pkg backend"
is good.

It could be noted somewhere that the backend supports both
audio and MIDI but the user is one `emerge --search sndio`
away from learning that if they wish.

What do you think about it?

Kind regards
Filip Kobierski

[gentoo-dev] [RFC] [PATCH] Making USE=sndio global

[Filip Kobierski]

Hi all,

as it has been over a month since my initial RFC and I have recieved no
responses I have decided to prepare the patches.
My first idea was for the use.desc to be
"Enable support for the sndio backend"
but looking at it now I thought I can do better so I came up with
"Add support for OpenBSD's sndio audio & MIDI backend".

It not only specifies that sndio supports MIDI but also points out that
the project is OpenBSD's which I think is a nice touch since otherwise
a "the" should preceed the word.

Hi all,

no one has responded to my proposal for yet another month so I am
bumping this again.

I still think this is a worthy change.

Kind regards
