Hi,
I'd like to make use of pandoc's header attributes (
https://pandoc.org/MANUAL.html#extension-header_attributes) to inject a
custom LaTeX \renewcommand{} definition in specific sections. My goal is to
have a minimalist markdown file for my CV (no tables or raw LaTeX, just
simple lists and #headers), and have a Lua filter identify which sections
have specific formatting needs (e.g wrap inside a 3-column table), which
will be taken care of by LaTeX.
Consider this input markdown,
> # qualifications {#id1 .CV content=list}
>
> ## 2011 | can type, delete, copy and paste
> ## 2021 | can *format*, sometimes
>
> # work in progress {#id2 .CV content=freetext}
>
> ## Beside lists, I am hoping to learn to format free text too, *someday*.

I would like to walk the AST, and immediately after headers with a specific
attribute, inject a \renewcommand{} based on the header's attributes, such
as (dummy example),
\renewcommand\subsection[1]{\textbf{#1}}
for sections with content=list and
\renewcommand\subsection[1]{\textit{#1}}
with content=freetext.
This is obviously a contrived example, the actual command I'm using is
actually to split a sub-header and format it as a table (dates | job
position | location) or various other tasks (e.g. changing emphasis colours
for different sections etc.).
I'm not familiar enough with the pandoc AST or lua to figure this out; I
looked at a related example ( * noexport-subtrees.lua *
<https://gist.github.com/tarleb/a0f41adfa7b0e5a9be441e945f843299#file-noexport-subtrees-lua>)
but here the situation is a bit different, as I need to create an
additional element (raw tex string) and append it to the original header.
Many thanks,
baptiste

You would have a function function Header(el) local attr = el.attributes -- you can do attr['foo'] to get the value of the 'foo' attribute -- now create a string with the macro: local macro = ... return { el, pandoc.RawBlock("latex", macro) } end You can fill in the blanks. ^ permalink raw reply [flat|nested] 4+ messages in thread
