Give formal index a proper title.
Use `Pass::formatted_help()` to assign the group, but still return `false` because the help text still comes from `Pass::help()`.
Tidy up some of the affected files' includes to make use of the shared `yosys.h` includes.
Keep techlibs folder hierarchy.
techlibs/* and passes/* groups are now nested under index_techlibs and index_passes respectively, with most (all?) of the passes/* pages getting proper headings, as well as backends/frontends/kernel. `index_passes_techmap` also references `index_techlibs`.
Split command reference toc in twain, one with maxdepth=2 and one with maxdepth=3, since passes and techlibs now have an extra level of nesting.
Move the `cmd_ref` link to the command reference, instead of top of the page.
Remove `index_internal` and `index_other` from the toc, and mark the pages as orphan. Internal commands get a note callout after the command reference toc (although this doesn't work for the pdf build), while other commands are linked in the warning for missing `source_location` (since that *should* be the only time when there are any commands in the "unknown" group).
Update autodoc extension versions, and mark the directives extension as not `parallel_read_safe` (it might be, but I'm not sure about how the xref lookups work if it is parallel so better to be safe).
Calling :cmd:title:`<cmd>` will generate a cross reference to `<cmd>`, but unlike :cmd:ref: which displays a literal block and puts the title (short_help) in the hovertext (the title field of an a-ref), :cmd:title: will display "<cmd> - <short_help>" as plain text.
Thus replacing the previous use case of referring to :doc:`cmd/<cmd>`.
Also refactor util py scripts to have more descriptive names.
Commands flagged as internal will display a warning, just like experimental commands.
Drop `passes/tests` group in favour of `internal` group, which is automatically assigned for any command without an assigned group which is flagged as internal.
Changes a bunch of :doc:`/cmd/*` to :cmd:ref:`*` with the intention of changing it later to something that replicates the previous effect of displaying the commands `short_help`.
Removes group parsing from command ref domain, instead relying on a 'groups' object in the cmds.json file.
`docs/source/cmd` is no longer ignored or cleaned.
Add `doc_string` field to `Pass` constructor
Add `docs/util/newcmdref.py` to contain command domain
Update `docs/util/cmdref.py` with `cmd:usage` and `cmd:optiongroup` for describing commands.
Functional, but WIP.
I was thinking about compiling the dummy example and including a simple example usage, but it turns out functional.h isn't (currently) available for extensions.
Acknowledge the minimal functional backend, highlighting what's new/different for our SExpr targets.
Add and use the reference `minimal backend`.
Use `note` directives to point out missing code sections (highlighting that the included diffs are not complete).
Racket *is* still strongly-typed, it's just dynamic instead of static. Adjust phrasing to reflect that.
Adjust some of the literal includes, adding a new section from the `Functional::AbstractVisitor`, splitting the `Module::write_eval()` in twain and adding a `smtlib.cc` literal include for the node iteration, as well as for the `FunctionalSmtBackend` to compare against the minimal backend.
Move `Backend` description up to minimal functional backend section.
Add `dummy.cc`, loosely based on `backends/functional/test_generic.cc` but as an actualy backend and without the memory testing.
Skeleton section for minimal functional backend, describing the aforementioned `dummy.cc`.
As the intro paragraph (now) says:
> This section will introduce the SMT-LIB functional backend and what changes are needed...
The example is intended to be read without prior knowledge of the SMT-LIB backend, but the previous version glossed over a lot and instead focused on *just* what was changed.
This version should now be easier to follow without prior knowledge, while still being able to learn enough about the `Smt` version to adapt it to a different s-expression target that isn't Rosette.
Also adds a few `literalinclude`s of smtlib.cc, which is now copied to `docs/source/generated` along with producing the rosette diff on the fly (which now also has up to 20 lines of context, enabling the full `Module::write()` diff to be literal included).
