Completely missing bitwise operators standard in Lua 5.3

im using this inside my script
local ast = CreateLuaParser(script)

FormatAst(ast)
PrintAst(ast)

i skip this BeautifyVariables(global_scope, root_scope) because it just rename stuff ..also it doesnt matter because the output is same as below but without variables being renamed.

this is my test script

function main()
select = gg.choice({
     "test1",
     "test2"
})
if select == 1 then test.show() end
if select == 2 then test.show2() end
end
local a = 1
b = "3(£+£+£+£+"
local c = false
test = {
    show = function()
        gg.alert("find me")
    end,
    show2 = function()
        gg.alert("yay me "..b)
    end
}
function what()
   gg.alert("yow")
end
what()
main()

and the script output this only

function main()
select = gg.choice({
     "test1",
     "test2"
})
if select == 1 then test.show() end
if select == 2 then test.show2() end
end
local a = 1
b = "3(£+£+£+£+"
local c = false
test = {
    show = function()
        gg.alert("find me")
    end,
    show2 = function()
        gg.alert("yay me "..b)
    end
}
function what()
   gg.alert("yow")
end
what()

it forgots the main() here's the crazy part if you do this below

function what()
   main()
   gg.alert("yow")
end
what()
main()

the output is

function what()
   main()
   gg.alert("yow")
end
what()

even if you do this

function what()
   main()
   gg.alert("yow")
end
function what2()
   gg.alert("yow")
end
what()
what2()
main()

the output will be

function what()
   main()
   gg.alert("yow")
end
function what2()
   gg.alert("yow")
end
what()
what2()

Coming from LÖVE, having require in your code throws an issue:

require "test"

luajit: minify.lua:205: file<1:3>: Bad symbol `´` in source.
stack traceback:
        [C]: in function 'olderr'

luajit 2.1

Can you please implement GlobalRenameIgnore?

Currently, the parser is unable to handle vararg function declarations like e.g.

local function printf(...)
	print(string.format(...))
end

local function printf_alternative(fmt, ...)
	print(string.format(fmt, ...))
end

as it always expects identifiers in the argument list.

Pull request #1 is a first, incomplete attempt to fix this. I've submitted my solution in #2.

Hi,
When I tried to run minify on the ltn12.lua file I get the following error:

lua: minify.lua:484: 43:23: ) expected.
stack traceback:
[C]: in function 'error'
minify.lua:484: in upvalue 'expect'
minify.lua:674: in upvalue 'funcdecl'
minify.lua:1290: in upvalue 'statement'
minify.lua:1310: in function minify.lua:1303
(...tail calls...)
minify.lua:3206: in main chunk
[C]: in ?

and the output file contains:
Tokens[-3] = .
Tokens[-2] = chain
Tokens[-1] = (
Tokens[0] = ...
Tokens[1] = )
Tokens[2] = local
Tokens[3] = arg

The function it is having this trouble with is:

-- chains a bunch of filters together
-- (thanks to Wim Couwenberg)
function filter.chain(...)
local arg = {...}
local n = select('#',...)
local top, index = 1, 1
local retry = ""
return function(chunk)
retry = chunk and retry
while true do
if index == top then
chunk = argindex
if chunk == "" or top == n then return chunk
elseif chunk then index = index + 1
else
top = top+1
index = top
end
else
chunk = arg[index](chunk or "")
if chunk == "" then
index = index - 1
chunk = retry
elseif chunk then
if index == n then return chunk
else index = index + 1 end
else base.error("filter returned inappropriate nil") end
end
end
end
end

print("Hello\32world!")

gets rejected with Invalid Escape Sequence '3'
