I am trying to write a lua filter which works on figure caption titles, i.e. stuff like "Figure 1" in the figure caption. See this question for background. Basically I want to make this "Figure 1" part in bold (including figure number).
However, it appears that when Quarto runs a lua filter the caption of the Image object in AST does not yet contain the figure title; the caption at this stage is [ Str "Your", Space, Str "Caption" ], whereas after Quarto is done (and you convert the output to native, for example) it becomes [ Str "Figure", Str "\160", Str "1", Str ":", Space, "Your", Space, Str "Caption" ].
My question: is there a way of running a lua filter in quarto after the cross-references and caption titles have been added?
Quarto supports quarto as a special specifier in the filter list, which allows to set the position of the default Quarto filters relative to other filters:
---
filters:
- run-me-first.lua
- quarto
- my-figure-modifier.lua
