gluasrcdiet

a fork of luasrcdiet, which supports glua features:

• continue keyword
• additional replaces not -> !, and -> &&, or -> ||, allowing to remove surrounding whitespaces too
• strip trailing commas before closing curly braces

see test.bat for usage

before

GlobalVariable = GlobalVariable or {}
function GlobalFunction()
	print('hello world!')

local var2 = {
	pos = Vector(0, 0, 0),
	ang = Angle(45, 0, 2),
	data = {
		msg1 = 'example',
		msg2 = 'cozy',
	},
}
local function myFunc(num)
	return num % 1337 == 0
end

hook.Add('Think', 'example', function()
	hook.Remove('Think', 'example')
	local fr = vgui.Create 'DFrame'
	fr:SetTitle(var)
	fr:SetSize(10, 100)
	for i, v in ipairs(fr:GetChildren()) do
		if myFunc(i) then
			break
		end
	end
	local superLongButUseless1, superLongButUseless2, superLongButUseful3 = 0, 0, 0
	for index = 1, 10 do
		if not myFunc(index) or not myFunc(index * 3) or (index > 3 and index < 10) then
			continue
		end
		superLongButUseful3 = superLongButUseful3 + index
	end
end)

overall, the code is 36% shorter (807 chars vs. 509), but it'll be much more resultative if you usually indent using spaces, not tabs

also, pay attention to some lines that became really times shorter:

before	after	comments
if not myFunc(i) or not myFunc(i * 3) or (i > 3 and i < 10) then	if!o(e)||!o(e*3)||(e>3&&e<10)then	(51.6%) using c-styled logical operators, you will be able not to place any spaces at all, gmod accepts it
local superLongButUseless1, superLongButUseless2, superLongButUseful3 = 0, 0, 0	local e,e,n=0,0,0	(21.5%) (luasrcdiet feature) renames local variables to as short as possible
local var2 = { pos = Vector(0, 0, 0), ang = Angle(45, 0, 2), data = { msg1 = 'example', msg2 = 'cozy', }, }	local e={pos=Vector(0,0,0),ang=Angle(45,0,2),data={msg1='example',msg2='cozy'}}	(68.7%) renamed table, removed whitespaces and trailing commas (there could be pretty enough in large config tables)
