Hello,

Auctex does not seem to properly font lock \autocites with multiple citations.

\autocites[][]{key1, key2} works fine but \autocites[][]{key1, key2}[but see][]{key3} results in neither "but see" nor "key3" getting the appropriate faces (which should be font-lock-variable-name-face and font-lock-constant-face, I believe).

Thanks!

Hi Alex,

I would say this is by design: \[Aa]utocites take multiple number of
[prenote][postnote]{key} and AUCTeX cannot look ahead to detect the
number of arguments which should be fontified.  Not satisfactory, but
not fixed easily, I think.

Best, Arash

Thanks for the follow up.

I was hoping that something like this could be used: https://fuco1.github.io/2017-06-01-The-absolute-awesomeness-of-anchored-font-lock-matchers.html

Setting the limit might be tricky though. I guess it could be the first close brace with a space or \ after it --- "} " or "}\", perhaps?

Alex

AUCTeX usually fontifies a fixed number of arguments, check here for how
[Aa]utocites are coded [1].  I'm not sure if it possible to change this
behavior without bigger surgery in font-latex.el.  OTOH, patches are
always welcome :-)

Best, Arash
