I pushed the following changesets so that the GUI terminal now handles bracketed paste mode and to improve handling of multi-line pasted input:


Marking as ready for test.

I can confirm that with Readline version 8.1, bracketed paste mode is now enabled by default.

Adding 'set enable-bracketed-paste off' to ~/.inputrc turns it off and the warning messages are suppressed again.

It seems there may be some pressure to make a small workaround fix to suppress the warning messages even if we don't have the energy to fully support bracketed paste in the terminal widget for now.

I believe this is the project that our Unix terminal widget is based on:


Note that the Windows version of this terminal is separate, but made to provide a similar widget interface, at least as far as the Octave command window is concerned.

The current sources of qtermwidget do appear to handle bracketed cut and paste.  However, we have made changes in our copy, so we can't simply update to the latest sources.

And, as Mike said, I'm not sure we want to keep this as the terminal implementation anyway.  I'd prefer to unify the Unix and Windows command window widgets to eliminate the duplication.

I've only read a little about this, but to clarify, I think that readline already supports this feature, therefore Octave already supports bracketed pasting as an input to its command line. The part that is broken here is the qterminal widget used in the GUI command window.

At the very least, I think we can patch our embedded copy of qterminal to simply discard these start and end sequences.

If we want to keep qterminal (not sure that we do), someone could look at updating the widget to actually support bracketed paste mode, or import patches if that has already been done to qterminal by someone else.

Activating bracketed paste mode in ~/.inputrc via:

set enable-bracketed-paste on

leads to messages like this in the terminal window:

>> undecodable token: \001b(hex)[?2004l
undecodable token: \001b(hex)[?2004h
