Makes progress getting "zig build test" to work on windows. Mostly
fixed issues around build configuration and added some branches throughout
the Zig code to return/throw errors for unimplemented parts.
I also added an initial implementation for getting the home dir.
The surface runs on the same thread as the app so if we use the app
mailbox then we risk filling the queue before it can drain. The surface
should use the app directly.
This commit just changes all the calls to use the app directly. We may
also want to coalesce certain changes to avoid too much CPU but I defer
that to a future change.
This makes a few major changes:
- cursor style on terminal is single source of stylistic truth
- cursor style is split between style and style request
- cursor blinking is handled by the renderer thread
- cursor style/visibility is no longer stored as persistent state on
renderers
- cursor style computation is extracted to be shared by all renderers
- mode 12 "cursor_blinking" is now source of truth on whether blinking
is enabled or not
- CSI q and mode 12 are synced like xterm
Fixes#400
This ensures the hollow box is shown even if the cursor is not in a
blinking state when unfocus happens. We still hide the cursor even on
unfocus if the terminal mode explictly asks for a hidden cursor.
This is based on our conversation on Discord and adds a setting for GTK
that allows disabling the GTK single-instance mode.
If this is off, it's possible to start multiple applications from the
same release binary.
Tested like this:
```
$ zig build -Dapp-runtime=gtk -Doptimize=ReleaseFast && ./zig-out/bin/ghostty --gtk-single-instance=false
[... starts new application ...]
```
and
```
$ zig build -Dapp-runtime=gtk -Doptimize=ReleaseFast && ./zig-out/bin/ghostty --gtk-single-instance=true
