I've done some progress on my implementation. There are good news and bad
news :)
I've managed to implement a snake_case/PascalCase conversion role for
literal blocks (``like_this`` is replaced by
:snakepascal:`like_this;;LikeThis`). The associated JavaScript and CSS code
I've developed works great too.
However, I haven't managed to replicate the same role for "reference"
links. Here's the code snippet that defines the :snakepascal-ref: role I'm
trying to create:
def snakepascal_reference_role(name, rawtext, text, lineno, inliner,
options={},
content=[]):
if "<" in text:
# Manually named reference
refid = text.split("<")[1].split(">")[0]
else:
# Automatically named reference
refid = text
node = nodes.reference(rawtext, text, refid=refid, classes=[
"snakepascal"], **options)
return [node], []
Usage:
Manually named reference: :snakepascal-ref:`
custom_multiplayer<class_Node_property_custom_multiplayer>`
Automatically named reference: :snakepascal-ref:`
class_Node_property_custom_multiplayer`
I thought setting the `refid` parameter would make Sphinx find the
reference automatically like it does with the :ref: role, but it seems to
just create a literal hash-link. I want to use the same reference
acquisition logic as Sphinx itself so I don't have to type out internal
documentation URLs fully.
(At the end of the day, I just want to associate a custom CSS class to the
reference link so it can be used from JavaScript.)
