Minification error with ...

[aryajur]

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

It seems the error is because the token parser does not know how to handle "..."?

Thanks for the detailed info, I'll see if I can fix and update it after work today.

I created a pull request #11 where it seems to be fixed.
