This was a regression. The previous logic would always show the cursor
if we were using a non-blinking cursor. But, if the terminal state is
explicitly requesting an invisible cursor (mode 25) then we need to hide
the cursor.
I couldn't get icons to work for the flatpak version, so I looked at the
reference here: https://docs.flatpak.org/en/latest/freedesktop-quick-reference.html
That says the path format is `share/icons/hicolor/<resolution>/apps/<icon>`.
That also matches what I have on my Ubuntu machines: icons are, for
example, located in these two locations:
- `/usr/share/icons/hicolor/128x128/apps`
- `~/.local/share/icons/hicolor/128x128/apps`
Note the `/apps`.
This menu got list in #215 and with it we lost the ability to use the
macOS emoji picker via the `Cmd+Ctrl Space` shortcut, for example.
This adds a standard Edit menu back to the main menu.
Previously, this would crash. Once the crash was fixed, it would hang
because we would only show confirmation if the terminal window had
focus.
This introduces some medium complexity logic to work around this:
1. If we are the key window, then show the confirmation dialog. Done.
2. Otherwise, if any other window is a terminal window and is key,
they're going to take it so we do nothing.
3. Otherwise, if we are the first terminal window in the application
windows list, we show it even if we're not focused.
Previously, we'd send renderer screen size updates and termio sigwnch
updates on every single resize event even if the screen size or grid
sizes didn't change. This is super noisy and given how many resize
events macOS sends, its also very expensive.
This commit makes it so that we only update the renderer if the screen
changed. If the screen size didn't change, the grid size couldn't have
changed either.
If the screen size did change, its still possible the grid size didn't
change since Ghostty supports fluid pixel-level resizing. We have to
send the screen size event to the renderer so all the GPU shader vars
are right but we do not have to send a termio event.
So, only if the grid size changed do we then notify the pty that the
terminal dimensions changed. Note that the resize event for ptys does
have a pixel-level x/y but I don't think the granularity is useful
beyond grid changes.
This adds support for what's commonly referred to as "non-native
fullscreen": a fullscreen-mode that doesn't use macOS' native fullscreen
mechanism and thus doesn't use animations and a separate space on which
to display the fullscreen window. Instead it's really fast and it allows
the user to `Cmd+tab` to other windows, with the fullscreen-ed window
staying in the background.
Another name for it is "traditional fullscreen" since it was the default
pre Mac OS X Lion, if I remember correctly.
Other applications that offer macOS non-native fullscreen:
- Kitty: https://sw.kovidgoyal.net/kitty/conf/#opt-kitty.macos_traditional_fullscreen
- wezterm: https://wezfurlong.org/wezterm/config/lua/config/native_macos_fullscreen_mode.html
- MacVim
- IINA: fc66b27d50/iina/MainWindowController.swift (L1401-L1423)
- mpv: https://mpv.io/manual/stable/#options-native-fs
- iTerm2
Adding this wasn't straightforward, as it turned out. Mainly because
SwiftUI's app lifecycle management doesn't allow one to use a custom
class for the windows it creates. And without custom classes we'd always
get a warning when entering/leaving fullscreen mode.
So what I did here is the following:
- remove SwiftUI app lifecycle management
- introduce `MainMenu.xib` to define the main menu via interface builder
- add `GhosttyAppController` to handle requests from the app
- add a `main.swift` file to boot up the app without a storyboard and
without SwiftUI lifecycle management
- introduce the `FullScreenHandler` to manage non-native fullscreen -
this is where the "magic" is
But since removing the SwiftUI lifecycle management also means removing
the top-level `App` that means I had to introduce the menu (which I
mentioned), but also tab and window management.
So I also added the `WindowService` which manages open tabs and windows.
It's based on the ideas presented in
https://christiantietze.de/posts/2019/07/nswindow-tabbing-multiple-nswindowcontroller/
and essentially keeps tracks of windows.
Then there's some auxilliary changes: `CustomWindow` and `WindowController` and so on.
Now everything still works, in addition to non-native fullscreen:
* opening/closing of tabs
* opening/closing of windows
* splits
* `gotoTab`
Worthy of note: when toggling back from non-native fullscreen to
non-fullscreen I had to manually implement the logic to re-add the
window back to a tabgroup. The only other app that supports tabs with
non-native FS is iTerm2 and they have implemented their own tab
management to keep the tab bar even in non-native FS -- that's a bit too
much for me. Every other app has non-native apps and doesn't have to
wory about it.
