Xcode: Delete line hot-key

Question

I'm looking for a way to map some hot-keys to "delete the line that my cursor is on" in Xcode. I found "delete to end of line" and "delete to beginning of line" in the text key bindings, but I am missing how to completely delete the line no matter what I have selected. TextMate has this functionality mapped to Ctrl+Shift+D and I'd like the same thing if possible. Any ideas?

Answer 1

Thanks for the help, Ashley. After some experimentation I mapped my favorite TextMate commands (duplicate line, delete line). I created the file ~/Library/KeyBindings/PBKeyBinding.dict and added the following:

{
    "^$K" = (
        "selectLine:",
        "cut:"
    );
    "^$D" = (
        "selectLine:",
        "copy:",
        "moveToEndOfLine:",
        "insertNewline:",
        "paste:"
    );
}

The added "deleteBackward:" backs up one line after removing the line's content. You could probably just use "selectLine:" as well.

You can set up a system-wide key binding file that will apply to all Cocoa apps.

To do what you want it should like like this:

In your home folder, Library/KeyBindings/DefaultKeyBinding.dict

{
    "^D" = (
        "moveToBeginningOfLine:",
        "deleteToEndOfLine:",
    );
}

I believe if you only want it to apply to Xcode you can name the file PBKeyBinding.dict instead but I didn't try that myself. You can read more about this system here and here.
