lua luq

Lua quick

Substitue most used lua keywords to a quick shortcut. Lua almost never use the ! character, then it is use!

is it really usefull ?

This tool is experiemental and made initialy for the fun. Nevertheless all parts (the loader, command wrapper, ...) could be reused to support a new language syntax.

shortcut convention

I use upper case for lua reserved word and lower case for usual function name.

Samples

Hello world

In lua :

local function hello()
	print("hello world!")
end
hello()

In luq :

!L !F hello()
	!p("hello world!")
!.
hello()

more sample

The test.luq.lua

In luq

#!x /usr/bin/env lua

!L luq = !<"luq"

!L data = io.stdin:read("*a")
!L qata = luq.encode(data)
!p(qata)
assert(data == luq.decode(qata))
!L delta = (#data-#qata)
!p("OK")
!p(math.floor(-delta/#data*100).."% ("..#data.." - "..#qata.." = "..delta..")")

list of substitutions

• local <-> !L
• function <-> !F
• return <-> !R
• if then else end <-> !I !: !E !.
• while do end <-> !W !D !.
• print <-> !p
• require <-> !<
• ! -> !x

There is some decode alternatives

• !T -> then
• !( -> do
• !) -> end

So we can have

• !I !T !E !. -> if then else end
• !W !( !) -> while do end

For the exact list take a look at https://github.com/tst2005/lua-luq/blob/master/luq.lua#L19-L33
