following the plan in https://github.com/NixOS/nixpkgs/pull/189318#discussion_r961764451
also adds an activation script to print the warning during activation
instead of during build, otherwise folks using the new CLI that hides
build logs by default might never see the warning.
mkAliasOptionModule should not default to mdDoc descriptions because
that can break out-of-tree users of documentation infrastructure. add an
explicitly-MD variant for now, to be removed some time after the MD
transition is complete.
Render un`_type`d defaults and examples as `literalExpression`s using
`lib.generators.toPretty` so that consumers don't have to reinvent Nix
pretty-printing. `renderOptionValue` is kept internal for now intentionally.
Make `toPretty` print floats as valid Nix values (without a tilde).
Get rid of the now-obsolete `substSpecial` function.
Move towards disallowing evaluation of packages in the manual by
raising a warning on `pkgs.foo.{outPath,drvPath}`; later, this should
throw an error. Instead, module authors should use `literalExpression`
and `mkPackageOption`.
Unlike the XML doc renderer, the AsciiDoc and CommonMark renderers don't
pretty-print certain complex types, like literal expressions, DocBook
literals, and derivations. These types are dumped into the documentation
as JSON.
This commit parses and unwraps these types when loading the
JSON-formatted NixOS options. The AsciiDoc and CommonMark renders have
also been combined into a single script to allow code reuse.
\<foo\> will often be displayed like \<foo>, for example by mkdocs.
I've tested a number of markdown renderers and they render html escape
sequences fine.
deprecate literalDocBook by adding a warning (that will not fire yet) to
its uses and other docbook literal strings by adding optional warning
message to mergeJSON.
leaving some newlines around after an admonition was closed causes the
newline rule to match, which in turn inserts literallayout newlines into
te xml output. that's not what we want.
with ever more options being markdown rather than docbook the conversion
time is starting to become a significant factor of doc build time.
luckily we can pre-convert all nixos option docs to MD and cache the
result of this conversion, then merge the already-converted json file
with user option docs. we leave options.json unconverted to keep it as
close to the actual nix code as possible.
during docs conversion it can be very useful to know exactly *where* the
error the script complained about is. the name of the option should be
sufficient since option merging is rather rare, and won't merge doc
attributes anyway.
Previously, the location logic was hardcoded, supporting only
Nixpkgs and NixOps properly, leaving other uses of the module
system without good location support.
Documents the _module.args option, motivated by many usages in Flakes,
especially with the deprecation of extraArgs
(78ada83361)
The documentation rendering for this option had to be handled a bit
specially, since it's not declared in nixos/modules like all the other
NixOS options.
