Hullo Guix,

I was surprised not to find cpupower available. It's a replacement
for the older cpufrequtils package. I didn't much feel like
re-writing my scripts or muscle memory, so I wrote a quick package.

I also rewrote the ‘atlas’ description to use that, instead of
a cpufreq-selector command for each separate core.

Kind regards,

T G-R

I made Gettext a ‘native-inputs’ and applied.

Thanks. I am genuinely puzzled as to why I put it in ‘inputs’ to
begin with.

Isn't gettext almost always a should-be-native-input?
If so, I'll try my hand at a linter patch.

Kind regards,

Thanks! I didn't know about @example.

It seems like some Texinfo syntax is encouraged (like @command), but
not the full set (package descriptions are full of abbreviations,
but no @abbr or @acronym anywhere). Is this by design?

More would certainly help get to the recommended 5-10 lines... :-)

Kind regards,

Nope it is not by design, the Guile (texinfo ...) modules just don't
implement these commands from GNU Texinfo, but should indeed.

Not always.  I'm working on a package currently whose primary tool is a 
shell script that calls gettext at runtime for i18n.

Is there a feature request / bug we could file somewhere on this? I
don't know what the upstream of Guile texinfo is, but it reads like it
should be extended.

Guile texinfo is maintained in Guile itself.  You can send a bug report
to <bug-guile@gnu.org>.

Thanks.

I could, but I have no time to interact with it due to personal
resources.
It would be better if someone else did this.
