luacodegen generates lua code from an ast. It is intended to be used with the tree produced by luaparse but this is not a hard requirement. The code generated is intended to have exactly the same ast as the initial input except with better formatting.
const luaparse = require("luaparse");
const luacodegen = require("luacodegen");
const tree = luaparse.parse("local function a(b) if (b) then return 1 else return 2 end end");
const code = luacodegen(tree);
/*
local function a (b)
if (b) then
return 1;
else
return 2;
end
end
*/
