Move MouseInput from TermAdapter to TermInput by carlos-zamora · Pull Request #4848 · microsoft/terminal

carlos-zamora · 2020-03-09T18:05:13Z

Summary of the Pull Request

Move the contents and functionality of MouseInput from TerminalAdapter
to TerminalInput.

References

#545 - VT Mouse Mode (Terminal)
#376 - VT Mouse Mode (ConPty)

Detailed Description of the Pull Request / Additional comments

Pretty straightforward. The MouseInput class was a bit large though so I
split it up into a few files. This should make TerminalInput a bit
easier to manage.

mouseInputState: enable some of the modes for mouse input. All saved
to _mouseInputState.
mouseInput: basically just HandleMouse() and any helper functions

Validation Steps Performed

Tests should still pass.

Yea I'm okay with this, but I'm curious why you decided to merge the classes into one rather than leave MouseInput encapsulated

I was wondering about the merging too. I dunno; did we set a bad precedent with TerminalCore? 😄

DHowett-MSFT · 2020-03-10T19:18:21Z

At the same time, if you don't dislike it too much (@zadjii-msft), i guess it consolidates "things about generating VT input" into a single place!

I didn't hate it enough to block it 😋

That's exactly what I was looking at... uh oh. But the nice thing now is that all kind of input is consistently in TerminalInput, rather than a random MouseInput object off on the side.

That said, I'll just redirect all calls to terminalMouseInput to go through the input buffer instead. I feel like that's cleaner but both of y'all know the code better so let me know if I'm going down the wrong path here.

Broke mouse mode in conhost

carlos-zamora · 2020-03-11T00:34:46Z

@DHowett-MSFT and I investigation findings:

the input sequences are getting added to the input queue but they just stay there
The removed callback would call WakeUpReadersWaitingForData(), whereas the new callback _HandleTerminalInputCallback() does not.

Looks like we need to make the input buffer wake up the reader if it's still asleep. I'll work on a proper fix for this tomorrow morning.

Verified that #4859 still works with the newest change.

DHowett-MSFT

I don't care that this variable is called _vtInputShouldSuppress. We need a followup Area-CodeHealth + Area-Input workitem to clean up whose responsibility it is to notify connected clients in conhost.

@msftbot forget everything i just told you

## Summary of the Pull Request Make TerminalControl synthesize mouse events and Terminal send them to the TerminalInput's MouseInput module. The implementation here takes significant inspiration from how we handle KeyEvents. ## References Closes #545 - VT Mouse Mode (Terminal) References #376 - VT Mouse Mode (ConPty) ### TerminalControl - `_TrySendMouseEvent` attempts to send a mouse event via TermInput. Similar to `_TrySendKeyEvent` - Use the above function to try and send the mouse event _before_ deciding to modify the selection ### TerminalApi - Hookup (re)setting the various modes to handle VT Input - Terminal is _always_ in VT Input mode (important for #4856) ### TerminalDispatch - Hookup (re)setting the various modes to handle VT Input ### TerminalInput - Convert the mouse input position from viewport position to buffer position - Then send it over to the MouseInput in TerminalInput to actually do it (#4848) ## Validation Steps Performed Tests should still pass.
