Ctrl + Shift + D should duplicate not only current line, but current selection if available

Very useful because it doesn't modify the clipboard

I've hacked the existing duplicate_line.py a bit. It copies the current line if nothing selected. Otherwise it inserts the selection after the selection. For duplicating complete lines you have to select the whole line (including the newline character).


import sublime_plugin

class DuplicateLineCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        for region in self.view.sel():
            line = region
            if line.empty():
                line = self.view.full_line(region)
            line_contents = self.view.substr(line)
            self.view.insert(edit, line.end(), line_contents)

Very well, thank you.

I've seen that some of my co-workers did indent it wrongly. You have to indent the last two lines at the same column like the "if line.empty()" is, otherwise nearly nothing will happen.
As always you install it by putting it into your User folder.

Very nice, thank you.
here is a screenshot for the indentation for those who don't know python too well:

The script shall be put for a default Mac OS X installation under ~/Library/Application Support/Sublime Text 2/Packages/User/duplicate_line.py

Thanks Eric :).

I believe this has been implemented already.. should't it be closed? 

The latest version of ST2 supports this out of the box: Cmd-Shift-D.
