Is There a File Comparison Control Available?

  • Patrick Altman Is There a File Comparison Control Available? May 05 2008, 21:33
    Does anyone know if there is a control that I can use in my Cocoa
    application to provide side by side file comparison support similar to
    FileMerge?  I would consider both controls for sale and that are open
    source.

    If none are readily available, then could someone point me in the
    direction of a good place on getting started on such a custom
    control?  Would I just composite a couple of NSTextView controls as a
    basis for the UI elements?

    Thanks,
    Patrick

    I don't know of any. I've done this before by using NSTask to run /usr/
    bin/opendiff, which launches FileMerge. (Which is what Xcode itself
    used to do, before version 3.0.)
