Is there any word or notepad like program that can do something like this?

See i have a long function.. but i have about 10 different ways to do that function.. and i need to edit about 50 variables like "[1]" to "[2]"... Is there any program that will let me copy and paste and change all the text i choose into something else? Cuz just editing functions from [1] to [2] gets boring fast.

If your using notepad, press the CTRL and H buttons at once.

It'll ask what to find, and what to replace what it finds with.

PSPduh showed me that. VERY handy little feature of Notepad.

soz i all ready worked out how to do this my self :Jump:
lua rocks

I know EminentJonFrost already helped with this, but I just wanted to say that Word has a function and you can say what to replace with what and it replaces all of those.

Hmmm also with my notepad of Win98SE its just the same as backspace...

maybe this might be of interest to you montrob:

Luaplayer v0.19
==========
- directory detection bugfix [moonlight]
- Changed System.loadModule to loadlib to work. [Oobles
the same as the traditional lua loadlib function
- Made loadlib check if a module is already loaded before trying
to load. [Oobles]
- Removed getLuaState export. No longer required. [Oobles]
- Made debugOutput work in the same way as printf in bootstrap. [Oobles]
- Added loadlib.prx kernel module. required for module loading. [Oobles]
- Added a module sample for manipulating images [Shine]

I havent checked it out yet, but it sounds like what you may be looking for. I'm gonna look into it now.

Edit - I found in the new Luaplayer (version 19) in the Samples folder, this script:

Code:

---

function rotate(image)
        local w = image:width()
        local h = image:height()
        local result = Image.createEmpty(h, w)
        for x=0,w-1 do
                for y=0,h-1 do
                        result:pixel(h-y-1, x, image:pixel(x, y))
                end
        end
        return result
end

function printRotated(x, y, text, color, image, rotateIndex)
        rotateIndex = math.mod(rotateIndex, 4)
        local w = string.len(text)
        local result = Image.createEmpty(w * 8, 8)
        result:print(0, 0, text, color)
        if rotateIndex > 0 then
                rotateIndex = rotateIndex - 1
                for i=0,rotateIndex do
                        result = rotate(result)
                end
        end
        image:blit(x, y, result)
end

cadetBlue = Color.new(95, 158, 160)

printRotated(132, 0, "Don't ask what Lua Player", cadetBlue, screen, 0)
printRotated(472, 76, "can do for you,", cadetBlue, screen, 1)
printRotated(160, 264, "ask what you can do", cadetBlue, screen, 2)
printRotated(0, 76, "for Lua Player!", cadetBlue, screen, 3)
screen.flip()
while true do
        screen.waitVblankStart()
end
