Extending the File Object?

[stretch65]

I don't have much experience with OOP in AHKv2, but I was wondering if it's
possible to add an extra function to the File object in a script.

The function I had in mind would do the same thing as File.WriteLine( "some text" ),
but would also send "some text" to my debugger (using "OutputDebug").

Is that even possible?

I don't believe that the File class is currently available globally from script. There's other classes that a similar strategy has to be used with I think. You basically have to use FileOpen to create an instance of a File object and then define a method on that object's base property. Something like this. You could obviously open any file first to create the method. I just chose StdOut.

Code: Select all

#Persistent

; Open a console window for this demonstration:
DllCall("AllocConsole")

f := FileOpen("*", "W")
f.base.DefineMethod("WriteLineDebug", (this, string) => !OutputDebug(string) && this.WriteLine(string))
f.close()

f := FileOpen("*", "W")
f.WriteLineDebug("This is a test")
f.close()

Thanks very much for this.
