Dumb Lua Parser is a library for tokenizing Lua code or creating ASTs (Abstract Syntax Trees) and converting the data back to Lua. It can also optimize and minify code.

The library is a single Lua file with no dependencies other than Lua itself. It works with Lua 5.1, 5.2, 5.3 and 5.4. LuaJIT should work too. MIT license.

local ast    = parser.parse(tokens)

parser.simplify(ast)
parser.printTree(ast)

local lua = parser.toLua(ast, true)
print(lua)
