- Cap the total number of requests at twice the maximum number of
keys (currently 263, so 526 requests). Basically you can set and then
query every key in one message. This is an absurdly high number
but should prevent serious DOS attacks.
- Clarify meaning of new hex color codes.
- Better handle sending messages to the renderer in a way that should
prevent deadlocks.
- Handle 0-255 palette color requests by creatively using non-exhautive
enums.
- Fix an error in the query reply.
Fixes#2099
This is another heuristic of sorts to make `window-padding-color=extend`
look better by default. If a fully covering glyph is used then we use
the fg color to extend rather than the background.
This doesn't account for fonts that may do this for whatever codepoints,
but I think that's a special scenario that we should just recommend
disabling this feature.
Ghostty previously incorrectly only created scrollback if the top/bot
margins were the full height of the viewport. The actual xterm behavior
is to create scrollback as long as the top margin is the top row and the
cursor is on the bottom margin (wherever that may be).
Kitty 0.36.0 added support for a new OSC escape sequence for
quering, setting, and resetting the terminal colors. Details
can be found [here](https://sw.kovidgoyal.net/kitty/color-stack/#setting-and-querying-colors).
This fully parses the OSC 21 escape sequences, but only supports
actually querying and changing the foreground color, the background
color, and the cursor color because that's what Ghostty currently
supports. Adding support for the other settings that Kitty supports
changing ranges from easy (cursor text) to difficult (visual bell,
second transparent background color).
