Synthesize VT mouse events and add mouse support to Terminal #4859

carlos-zamora · 2020-03-09T23:30:21Z

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 Enable Passthrough for VT Input Mode in ConPty #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
(Move MouseInput from TermAdapter to TermInput #4848)

Validation Steps Performed

Tests should still pass.

Okay, I played with a build of this extensively and only found two issues. One isn't even a bug, it's just ~ ~ weird ~ ~.

(the bug) if you launch mc and un-focus the window, your first click-drag inside the window will begin a selection and send a mouse event. All click-drags after that will extend the selection and send mouse events.
(the weirdo) if you're using standard X10 coordinate mode, which can only address cells up to 94x94, clicking outside of the 94x94 rectangle in the top left of the terminal causes normal mouse events to fire!

2 is a weird case and the encoding is not often used, i bet, so we can ignore it.

Also, yes, gotta figure out how that "revert" commit got in here.

These are definitely nits, so fix them and I'll sign off on this too. I know Dustin mentioned some other bugs, but IMO we can just fix them in post. They seem pretty trivial comparatively. Let's file them, and get these all in
