Line number of input file

Line number of input file

Is there a way to get at the current line number of the current input file 
in a Lua filter?

I can get the input file via PANDOC_STATE.input_files alright, but what 
about the input line?

I understand that Lua filters work on Pandoc ASTs, so the raw string input 
is already transformed. I used to save input line numbers with AST nodes 
when I wrote parsers. Is there such facility in Pandoc's ASTs? Writing a 
custom reader?

The CommonMark parser can be used with the `sourcepos` extension.
Enabling the extension will add positional information via div and span
attributes. The other parsers in pandoc don't have a comparable feature.

Ah, ok, thanks.
