A custom writer to extract documents' metadata as JSON

[massifrg]

Hello,
I just published a Lua custom writer for Pandoc that extracts the metadata from a document as a JSON object.

I did a rapid search for similar solutions, but I could not find one, so I wrote mine.

The script can

• keep the formatting of MetaInlines and MetaBlocks
• detect integer and decimal numbers and store them as numbers in the resulting JSON

There is indeed a simpler solution. Create a template meta.tpl containing just

$meta-json$

Then pandoc yourdocument.md --template meta.tpl
This variable is described in the manual under "Variables set automatically."

Oops, I did not know of meta-json.
Yes, it's definitely simpler (unless I overstretch the fact that my code can detect numbers... 😁 )
