425: load this file @ the start of a lua 4 script and you can run it in lua 5.
works for many simple scripts, but fails on several things on the file handling.
--------------------------------------
-- 425 by plop
--------------------------------------
-- convert lua 4 code into lua 5.
-- not the best way but it instandly converts simple scripts.
-- add "require("425/425.lua")" above all the other code
-- in the lua 4 script.

the next script rewrites all lua 4 syntax and safes it into a new file in lua 5 syntax.
the failing input/output from 425 is droped in this.
so you have 2 rewrite that manualy @ the moment.

The reverse would probably be more usefull so Lua devs can start making Lua 5 scripts for the current Ptokax.

save the script as 425.lua inside a folder called 425.
the script can't be in the scripts folder from ptokax itself as ptokax would launch it as a normal script.

Does Lua4 understand the function require ?

nope, use dofile here.

Hi ppl,
I need help!
How can I convert script in LUA 4 to LUA 5 with convertor by NotRabidWombat?
PLS HELP ME!!!!

wombat's version works the other way around, it converts lua 5 scripts back 2 lua 4.

isn't there a way to write a little prog that can automatically replace the lua 4 commands with lua 5.02 commands?
so in fact really changing the script?
like you load a lua 4 script in the program, hit the button convert and it will convert everyting it can convert and will point out what he can't convert?
Lot's of programs have an option called wordreplace, can't that be used....
*edit*
because i want to really change the script so i can try to convert it to a dch++ script eventually :D
and it isn't a simple script i wanna change i think...
it's the shoutcast script....

Every editor has a "replace all" function. This will satisfy you and it's much, much safer IMHO. BTW, if there is a % before a variable name (%var) it should be replaced to var.

the second script i posted does that, just you need a bit more buttons, namely your keyboard.
but there is a topic which explains how 2 use a certain editor with 2 user commands 2 do the same.

this next script converts the new dataarrival handling from lua 5.0 ptokax versions.
works just like 425.lua.
