Leveraging custom variable set in _quaro.yml in a filter script?

[dweng0]

Description

Hi All,

I have created an extension that allows you to inject react components into md/qmd documents. The script that does this also checks for things like .css and supporting .js/.ts files.

Where the script "looks" for css/ts/js files is currently hardcoded here

local component_folder = '_components'
local resources_folder = '_components'

I would like to be able to use a custom _quarto metadata variable and leverage that instead

local component_folder =  quarto.???.component-location
local resources_folder = quarto.???.resource-location

I haven't seen any information about this in the documentation but was wondering if it is something that can be achieved?

All metadata are in Meta as described in Pandoc's documentation (which is referenced in Quarto's documentation).
See:

• https://quarto.org/docs/extensions/filters#development

See the following extension which uses and adds meta data: https://github.com/mcanouil/quarto-lua-env.
