How do I delete the current line using AutoHotkey?

Question

Using an AutoHotkey script I'd like to set the keyboard command Ctrl+D to delete the current line in any active Windows app.

How?

Answer 1

^d::Send {Home}{ShiftDown}{End}{Right}{ShiftUp}{Del}

Might not work in all edge cases, but passes some very basic testing in Notepad. =~)

Answer 2

HaveSpacesuit's answer works but after using it for a while I realized it deletes the active line and sometimes re-positions the spacing of the line below.

This led me to rethink his solution. Instead of going from the front of the line to the back, I tried going from back to front. This solved the re-positioning issue.

SendInput {End}
SendInput +{Home}
SendInput ^+{Left}
SendInput {Delete}

There is still a small problem though. If the cursor is on an empty line, with more empty lines above, then all empty lines get deleted.

I don't know a key combo to replace ^+{Left} that doesn't have this behavior so I had to write a more comprehensive solution.

^d:: DeleteCurrentLine()

DeleteCurrentLine() {
   SendInput {End}
   SendInput +{Home}
   If get_SelectedText() = "" {
      ; On an empty line.
      SendInput {Delete}
   } Else {
      SendInput ^+{Left}
      SendInput {Delete}
   }
}

get_SelectedText() {

    ; See if selection can be captured without using the clipboard.
    WinActive("A")
    ControlGetFocus ctrl
    ControlGet selectedText, Selected,, %ctrl%

    ;If not, use the clipboard as a fallback.
    If (selectedText = "") {
        originalClipboard := ClipboardAll ; Store current clipboard.
        Clipboard := ""
        SendInput ^c
        ClipWait .2
        selectedText := ClipBoard
        ClipBoard := originalClipboard
    }

    Return selectedText
}

As far as I can tell this produces no unexpected behaviour.

However, be careful if you're using a clipboard manager as this script uses the clipboard, if necessary, as an intermediary to get the selected text. This will impact clipboard manager history.
