Issue pulseSupport -> does it make sense to have a global 'enable pulse for all packgages' config.pulseSupport = true flag?
packages could be using: config.pulseSupport or false to disable by default then. Gentoo use flags traditionally have been used to enable commonly used flags such as 'qt support' 'gtk support' or similar. in the specific pulse case I was told on irc that most packages like mplayer even work with pulse without having pulse built in. But same applies to jackd or whatsoever. The next question is: Which flags might be worth adding right now (because for instance this would also mean changing flags for sox using consistent naming which uses enablePulseaudio something flag). And how / where would those global flags be documented ? Having a defaultFlags = { config.sox = null; # does this cause the package default being used in "config.sox or false" ? config.pulseSupport = null; # please note: you can enable, but most packages will work with pulse without doing so config.qtSupport = null; config.gtkSupport = null; } And then there was a common way to document and set the same behaviour which affects many packages. Maybe there is already a way which I might have missed? Thus package defaults could look like this: pulseSuport ? let flag = 'pulseSupport'; let package = 'sox'; in config.$flag or config.$package.$flag or false; ^ global ^ package global ^ derivation default So you can set nixpgks config to either pulseSupport = true -> all packages mplayer.pulseSupport = true -> mplayer only or still override with .override ( .. ) the known way. I'm not going to change anything - just want to understand current situation and whether its worth thinking about it.
