now nix-doc-munge will not introduce whitespace changes when it replaces
manpage references with the MD equivalent.
no change to the manpage, changes to the HTML manual are whitespace only.
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.
In the default configuration we have timers for creating and deleting
snapper snapshots, and it looks like if we just create configs with
correct mountpoints we will get automatic snapshots (which either
used to be true, or seems to be only true on Archlinux according to
their wiki). In default snapper configuration TIMELINE_CREATE and
TIMELINE_CLEANUP are set to "no", so just providing configs won't
be enough for having automatic backups, which are the main usecase
for snapper. In other linux distributions you would use `snapper
create-config` to generate configs for partitions and you'd have a
chance to notice that TIMELINE_CREATE is set to no. Also, my guess is
that it might be set to no by default for safety reasons in regular distros,
so that the config won't be actioned upon until the user finishes
customizing it.
