The repo is pragtical-c3, but all plugins here should work just fine with the Lite XL.

For the LSP support, download the lsp plugin, then download/build from source the latest release of the tonis2 c3lsp, then add it to the PATH. Then add the following code into the init.lua

local lsp = require "plugins.lsp"

lsp.add_server {
  name = "c3lsp",
  language = "C3",
  file_patterns = { "%.c3$" },
  command = { "c3lsp", "--stdio"  },
  transport = "stdio",
}
