Testing luaposix-33, I stumbled upon these things: * The files in /usr/share/lua/5.2/posix/ use a variable _DEBUG which is not declared local. This causes programs to crash where "require 'strict'" p

Yes! More like `setmetatable("", {__index = string})`, actually: http://www.lua.org/source/5.2/lstrlib.c.html#createmetatable Just one more example of how Lua doesn't care about string when using __i

Replace s:gsub with msg:gsub (msg being the variable you want to call gsub on). You'll also need to return the result of gsub if you want to use it outside of modify_content_length (strings are immut

It was thus said that the Great Thomas Jericke once stated: Interesting. Because in my mind, I was parsing it as a,b,c in foo = (x,y,z in bar) in baz (left to right) That is: foo.a = baz[bar.x] foo.b

--Original Message-- I am not really sure if I should answer any questions including the words "foo" and "bar" but I try. It probably should expand to: foo["a", "b", "x"] = bar["x", "y", "z"] Now the

The line 'b = one' should at least be 'b = a.one' to refer properly. But it then still won't work because (iirc) the righthand side of 'a = { ...' is evaluated before it is being assigned to 'a', so
