You know, there are editors that automatically do the indenting for you. I'm so used to that by now that when such a program is not available, it actually hurts to write code.

yeah, notepad++ is ace
typing the " " (space 4x) is a real pain in the arse when you cant press TAB.

That reminds me the way how Java programmers usually compare strings:
Code: Select all
if ("stringValue".equals(stringVariable)) ...
When I've first seen this I was wondering why don't they simply write:
Code: Select all
if (stringVariable.equals("stringValue")) ...
The reason is quite simple. In case the stringVariable is null, the first condition evaluates to false, but evaluation of the second one causes NullPointerException.

That's very basic. What I meant more was you type
function foo(a, b)<ENTER> and the editor puts a tab on the new line. Same thing, you write
end and the editor moves that line one tab to the left.
You can write a while program, never once press tab or shift-tab and still have a completely indented source file.

Oh that, yeah that too (SCITE does that i think) - anyway I don't like automatic indentation*2 now because i am so used to np++)

Yeah, I miss the times I programmed c++ using an IDE that you do that kind of stuff and much more...actually, I think debugging is the feature I miss the most. Nowadays its just me, textwrangler (great free program btw) and LOVE.
I don't suppose any of you have a Lua IDE hidden somewhere in your old disks, do you?

TextWrangler IS great, I use it whenever I am not using Windows.
Lua IDE's are virtually useless unless you have a framework specific idea, Lua ide's can probably only provide better support for native Lua libraries and some syntax.

Okay, I haven't had much time to think about this, but I think this is the minimum "gimme" that you'd have to take to obfuscate code:
Why? Because from there we can build arbitrary strings and execute arbitrary code.
Code: Select all
_._=_.__[_.__] -- String.char function via the string metatable
_["!"]=(#"##")^(#"####")*(#"#######") -- 112, or lowercase p
_["@"]=_._(_["!"]+(#"####")).._._(_["!"]+(#"#########")).._._(_["!"]).._._(_["!"]-(#"###########")) -- "type"
_["$"]=_._(_["!"]-(#"####")).._._(_["!"]-(#"#")).._._(_["!"]-(#"##")^(#"####")+(#"#")).._._(_["!"]-(#"############")) -- "load"
_["*"]=_.___[_["$"].._.___[_["@"]]("")] -- loadstring function
Once you're at loadstring, you can basically do anything you want.
I couldn't figure out how to get to "char" from just symbols and _G.
Edit: fixed a typo
