Hooks to set attributes for different parts of the page. #1416

Open Udi-Fogiel opened 3 months ago

Brief outline of the enhancement

I'm not sure if it is already possible but it would be nice to have some hooks to control the attributes (in the LuaTeX meaning) of different parts of a page, i.e. page number, headings, footnotes, marginpars etc.

This is a similar concept to \normal color, but \normalcolor is used inside the page body, having a separate hook for other parts would be nice. Maybe one hook for all parts which are not the page body will suffice, but of course will be less configurable.

One use case is a problem I'm facing in https://github.com/Udi-Fogiel/lua-lineno/issues/1 but I don't think this is specific to this case. It's probably common to want different parts of the page to behave differently, e.g. default colors for footnotes. OpTeX for example provides \_resetattrs, see pages 114 and 120 of optex-doc.pdf.

I did not add minimal examples as i did not have a good idea for one. You can explore the examples in the linked issue (the package is not released yet so I thought adding it in a minimal example will add confusion).

It looks like I'm not the first one who thought it would be useful https://github.com/zauguin/luaul/blob/4c90c40761a2f7f5f78f2e098e505db68afc0b67/lua-ul.dtx#L1251-L1255

This will be part of the tagging project when we come to the output routine: it will be addressed when it is needed as part of the overall approach.
