When a with bg is selected, the cell's regular background will be blended
with 50% opacity selectionBackground in order to retain the bg color info
as well as getting the color to change and getting decent contrast.
This commit also fixes a terrible, nasty bug where the standalone shared
renderer tests were causing the terminal to open multiple times and not
get the WebGL addon activated the second time. So some tests were actually
testing the DOM renderer :o
Fixes#4918
I opted for consistency with the key event handler over our more modern
approach, we can migrate them at the same time if we end up returning
a disposable.
See microsoft/vscode#76381
Add support to ANSI OSC52 sequence to manipulate selection and clipboard
data. The sequence specs supports multiple clipboard selections but we
only support the common ones, system and primary clipboard selections.
This adds a new event listener to the common terminal module
`onClipboard` to allow external implementations to hook into it.
The addon uses the browser Clipboard API to read/write from and to the
clipboard. The default `ClipboardProvider` uses the browser Clipboard
API. This means it only supports read/write to and from the system
clipboard.
