While the API isn't really big, I think it would save me time rather than doing a bunch of "term.redirect(peripheral.wrap(side)) mycode() mycodeagain() term.restore() write("Did something")".
Currently I added normal write/print functions, flashing text and marquee left and right. More is coming.
Current functions:

Spoiler

writeM(side, text) - Write text on the monitor.
printM(side, text) - Print text on the monitor (it adds an extra line).
writePos(side, text, xpos, ypos) - Write text at a specific point.
slowPrint(side, text) - Slowly print text on the monitor.
slowPrintPos(side, text, xpos, ypos) - Slowly print text at a specific point.
clear(side) - Clear the monitor's screen.
flashyText(side, text, sleep, times) - Flash text on the monitor.
flashyTextPos(side, text, xpos, ypos, sleep, times) - Flash text at a specific point.
marqueeLeft(side, text, ypos, sleep) - Slide text from right to left.
marqueeRight(side, text, ypos, sleep) - Slide text from left to right.
The marquee functions now work properly thanks to Lyqyd.
goto(side) - Redirect to a monitor quickly (term.redirect(peripheral.wrap("right")) vs monitorapi.goto("right")). Use term.restore() to go back.
runprgm(side, prgm, args) - Run a program on the monitor.
run(side, func) - Run some lua code. For func, either put a function name or do "function() yourcodehere() end".

You're calling a function that doesn't exist. It would be monitorapi.writeM(side, text), not write since it was calling itself and not the OS function write(). Unless someone can think of a workaround, some of them will have an M after that for Monitor.

Ok thanks, I forgot the monitorapi part :/

[mrgreaper]

this looks majorly useful, thank you

[bobster71]

I agree with mrgreaper. Very nice. Very useful. Thanks. Saves me the trouble of building something like it.

the long sentences dont appear it simply skips them (ignore the remed out parallel line i wanted to have multiple lines scrolling when i first made it but that wont work due to limitation of lua)

also when the testing2...... and 1 line scroll they start on the right as the whole word and disapear when the first letter hits the left side, they dont scroll like a marque should if that makes sense

im guessing its an error with the way i called the api?

I had trouble trying to make it like a real one, where it would be "testing" then "esting" then "sting" and so on. I tried to make it and I didn't get it working. For now, you can make the monitor longer and cover the sides with blocks like RedPower cover plates (when the mod is updated). If anyone knows how to make it like a real marquee please tell me. I'll keep trying to make it work properly. Sorry, that's how it is right now. />

The basic functionality of the text moving from one side to another works though.

Edit: You could also separate the long text into several lines.

[ihaveamac]

Version 1.1 now here, added monitorapi.goto(side) (replacement for term.redirect(peripheral.wrap("side")) and monitorapi.runprgm(side, prgm, args). />

how did they do it with the space ship animation on the hidden starwars film ? that used text scrolling
(if you dont know what im talking about build a big monitier but a computer under it then type cd rom cd programs cd secret and run monitor top alongtimeago)

mind you i guess they knew exactly what lines they were having so it could be just a load of write commands

shame we cant convert a line of text into seperate 1 char per variable and then write the variables one by one and scroll that way

In that program, it does use a bunch of print lines, so it does something like print("test") then print("est") then print("st") and so on. The code for the marquee function in this doesn't do that, it does the simple function of moving text from one side to another and doesn't use a bunch of print lines.

I never got CC 1.32 since I never paid attention. I didn't really use mods for 1.2.4 other than TMI and a few others. I'll try to get CC for 1.2.5 when it comes out and try it.

Doesn't work. It just printed the text but didn't scroll.

Yes, CC1.32 works with 1.2.5.

i don't reach to use runprgm this is a part of code
:
runprgm("Top", "time")

how i can run the program ?
scuse me i'm new about computercraft and non english xD

No, it's fine. I made this to make it easy for new lua programmers to do stuff with monitors.

Did you save the file in the apis directory? If you did, you need to do monitorapi.runprgm("top", "time") or else it doesn't know what API to use.

:3 Oh, monitors! I should make monitor programs!

These may marquee properly:

function marqueeLeft(side, text, ypos, sleep)
    if peripheral.isPresent(side) then
	    term.redirect(peripheral.wrap(side))
	    local sx, sy = term.getSize()
	    text = string.rep(" ", sx - 1)..text
	    for i=1,string.len(text) do
		    term.clearLine()
		    displayString = string.sub(text, i, math.min(string.len(text), i + sx - 1))
		    write(displayString)
		    os.sleep(sleep)
	    end
	    term.clearLine()
	    term.restore()
    end
end
function marqueeRight(side, text, ypos, sleep)
    if peripheral.isPresent(side) then
	    term.redirect(peripheral.wrap(side))
	    local sx, sy = term.getSize()
	    text = string.rep(" ", sx - 1)..text
	    for i = 1,string.len(text) do
		    term.clearLine()
		    displayString = string.sub(text, -i, math.min(string.len(text), i + sx - 1))
		    write(displayString)
		    os.sleep(sleep)
	    end
	    term.clearLine()
	    term.restore()
    end
end

[ComputerCraftFan11]

You should add lua.

function mFunction(side, functionname)
  term.redirect(peripheral.wrap(side))
  functionname()
  term.restore()
end

function test()
  print "Hello world!"
end

mFunction("left", test)

Thanks, I'll try this out when I can. /> I've never heard of math.min() though.

I'll try this out. It could be "monitorapi.lua("left", function() print("HELLO WORLD") end)". (yes, that should work)
