Lua init script for an extension?

[paulwkc]

Description

Within an extension, I want to include some global Lua functions and update package.path for all lua filter files.

In pandoc, I can use init.lua (https://pandoc.org/lua-filters.html#lua-interpreter-initialization).

How to do that in quarto ? Can I have an init.lua in an extension ?

local utils = require("relative/path-to/file.lua") should work.

It seems some confusion here, or correct me if I'm wrong.

Explicitly, can we do below in quarto ?

1. in init.lua :

   -- 1. provide some global functions, like custom_debug() for filter1.lua
   -- 2. add full-path-to/my-lib/ to package.path, for util-glob.lua below , and like libapi1.lua in filter2.lua
   require 'util-glob'

2. in filter1.lua , use custom_debug directly :

   local function func1()
     custom_debug(...)
   end
   ...

3. in filter2.lua , require package directly :

   require 'libapi1'
   ...
