the conversion procedure is simple: - find all things that look like options, ie calls to either `mkOption` or `lib.mkOption` that take an attrset. remember the attrset as the option - for all options, find a `description` attribute who's value is not a call to `mdDoc` or `lib.mdDoc` - textually convert the entire value of the attribute to MD with a few simple regexes (the set from mdize-module.sh) - if the change produced a change in the manual output, discard - if the change kept the manual unchanged, add some text to the description to make sure we've actually found an option. if the manual changes this time, keep the converted description this procedure converts 80% of nixos options to markdown. around 2000 options remain to be inspected, but most of those fail the "does not change the manual output check": currently the MD conversion process does not faithfully convert docbook tags like <code> and <package>, so any option using such tags will not be converted at all.

Unfortunately, we cannot download ${name} automatically.

Please purchase a legitimate copy of Quake 3 and change into the installation directory.
|
|
|

You can either add all relevant files to the nix-store like this:
|
|
mkdir /tmp/baseq3
|
|
cp baseq3/pak*.pk3 /tmp/baseq3
|
|
nix-store --add-fixed sha256 --recursive /tmp/baseq3
|
|
|
|
Alternatively you can set services.quake3-server.baseq3 to a path and copy the baseq3 directory into
|
|
$services.quake3-server.baseq3/.q3a/
|
|
'';
|
|
