Original Pull Request: https://github.com/microsoft/terminal/pull/7143

State: closed
Merged: Yes

This PR adds support for the ANSI crossed-out graphic rendition
attribute, which is enabled by the SGR 9 escape sequence.

  • Support for the escape sequences and storage of the attribute was
    originally added in #2917.
  • Support for drawing the strikethrough effect in the grid line renderer
    was added in #7107.

Since the majority of the code required for this attribute had already
been implemented, it was just a matter of activating the
GridLines::Strikethrough style in the Renderer::s_GetGridlines
method when the CrossedOut attribute was set.

VALIDATION

There were already some unit tests in place in VtRendererTest and the
ScreenBufferTests, but I've also now extended the SGR tests in
AdapterTest to cover this attribute.

I've manually confirmed the first test case from #6205 now works as
expected in both conhost and Terminal.

Closes #6205
