I'm working on a programm, who read a file line by line and run the content of the file with load(). But theres a problem: A function is in a file normaly in more than one line. For example:
function test()
print("test")
end
If load() only get "function test()" it gaves a error, that end exeptet. Why can I make this work?

Don't run individual lines of a file. This will screw up more than functions, local variables will not work. Since local variables are considered good practice, this will break the majority of programs.
What do you intend to accomplish by running individual lines of a file?

I want to make a debugger with run a Programm line by line and show, waht the Program does and read/write Variables.

Somewhere in this dimension... I think.

Warning: Psuedocode detected!
count = 1
everyOther = false
debugLine = "<some code here>"
load(readFunction)
function readFunction(file)
if not everyOther then
line = readLine(count)
everyOther = true
return line
else
everyOther = false
count = count + 1
return debugLine
end
end

This is, unfortunately, impractical within CC. It would work for only the simplest of programs - those without loops or local variables, or any number of things.
IIRC, the debug library is included with CCTweaks. That may be worth looking into if you want to make a proper debugging tool.

One way to log all the functions called would be to set a custom env for the file which has an __index that wraps every requested function inside another one which then logs the stuff, or you return the original function and just log that the function has been accessed.
