Re: Which parts of Lua C-code handle string literals and multi-line comments?

You can start by learning LPeg and LPegRex.
LPegRex contains a grammar for parsing Lua:

https://github.com/edubart/lpegrex/blob/main/parsers/lua.lua

and it defines the syntax for comments - long and short - here:

https://github.com/edubart/lpegrex/blob/main/parsers/lua.lua#L113

Lua provides support for multi-line string literals invoked by `[[` and

I have searched Lua C-code for `--[[`, `--[=` and `[[` but failed to
find this patterns which I would like to replace for custom purposes
with another ones.

Any hints towards where to look and what to change?
