If some of the commits in this PR have problems with them I'm perfectly
fine with the others being cherry-picked out while the problems are
addressed.
The biggest/broadest reaching changes in this PR come from converting a
lot of code to use decl literals where possible, so there are a lot of
files where only a handful of lines are modified very slightly.
This commit changes a LOT of areas of the code to use decl literals
instead of redundantly referring to the type.
These changes were mostly driven by some regex searches and then manual
adjustment on a case-by-case basis.
I almost certainly missed quite a few places where decl literals could
be used, but this is a good first step in converting things, and other
instances can be addressed when they're discovered.
I tested GLFW+Metal and building the framework on macOS and tested a GTK
build on Linux, so I'm 99% sure I didn't introduce any syntax errors or
other problems with this. (fingers crossed)

Previously, Ghostty used a static API for async event handling: io_uring
on Linux, kqueue on macOS. This commit changes the backend to be dynamic
on Linux so that epoll will be used if io_uring isn't available, or if
the user explicitly chooses it.
This introduces a new config `async-backend` (default "auto") which can
be set by the user to change the async backend in use. This is a
best-effort setting: if the user requests io_uring but it isn't
available, Ghostty will fall back to something that is and that choice
is up to us.
Basic benchmarking both in libxev and Ghostty (vtebench) show no
noticeable performance differences introducing the dynamic API, nor
choosing epoll over io_uring.
Add a `+boo` command to show the animation from the website. The data
for the frames is compressed during the build process. This build step
was added to the SharedDeps object because it is used in both
libghostty and in binaries.
The compression is done as follows:
- All files are concatenated together using \x01 as a combining byte
- The files are compressed to a cached build file
- A zig file is written to stdout which `@embedFile`s the compressed
file and exposes it to the importer
- A new anonymous module "framedata" is added in the SharedDeps object
Any file can import framedata and access the compressed bytes via
`framedata.compressed`. In the `boo` command, we decompress the slice
and
split it into frames for use in the animation.
The overall addition to the binary size is 348k.

## Changes
1. Fixed documentation generation in `actions.mdx`:
- Fixed an issue where the last action's documentation was [not properly
generated](fe6c69263c/docs/config/keybind/reference.mdx (crash))
- Ensured all actions' documentation is correctly included in the output
2. Improved `ghostty +list-actions --docs` command output formatting:
- Grouped related actions together with shared documentation
- Added proper spacing between action groups

```
ignore:
Ignore this key combination, don't send it to the child process, just
black hole it.
unbind:
This action is used to flag that the binding should be removed from
the set. This should never exist in an active set and `set.put` has an
assertion to verify this.
csi:
Send a CSI sequence. The value should be the CSI sequence without the
CSI header (`ESC [` or `\x1b[`).
esc:
Send an `ESC` sequence.
text:
Send the given text. Uses Zig string literal syntax. This is currently
not validated. If the text is invalid (i.e. contains an invalid escape
sequence), the error will currently only show up in logs.
cursor_key:
Send data to the pty depending on whether cursor key mode is enabled
(`application`) or disabled (`normal`).
reset:
Reset the terminal. This can fix a lot of issues when a running
program puts the terminal into a broken state. This is equivalent to
when you type "reset" and press enter.
If you do this while in a TUI program such as vim, this may break
the program. If you do this while in a shell, you may have to press
enter after to get a new prompt.
copy_to_clipboard:
paste_from_clipboard:
paste_from_selection:
Copy and paste.
copy_url_to_clipboard:
Copy the URL under the cursor to the clipboard. If there is no
URL under the cursor, this does nothing.
increase_font_size:
decrease_font_size:
Increase/decrease the font size by a certain amount.
reset_font_size:
Reset the font size to the original configured size.
clear_screen:
Clear the screen. This also clears all scrollback.
select_all:
Select all text on the screen.
scroll_to_top:
scroll_to_bottom:
scroll_page_up:
scroll_page_down:
scroll_page_fractional:
scroll_page_lines:
Scroll the screen varying amounts.
adjust_selection:
Adjust an existing selection in a given direction. This action
does nothing if there is no active selection.
jump_to_prompt:
Jump the viewport forward or back by prompt. Positive number is the
number of prompts to jump forward, negative is backwards.
write_scrollback_file:
Write the entire scrollback into a temporary file. The action
determines what to do with the filepath. Valid values are:
- "paste": Paste the file path into the terminal.
- "open": Open the file in the default OS editor for text files.
The default OS editor is determined by using `open` on macOS
and `xdg-open` on Linux.
write_screen_file:
Same as write_scrollback_file but writes the full screen contents.
See write_scrollback_file for available values.
write_selection_file:
Same as write_scrollback_file but writes the selected text.
If there is no selected text this does nothing (it doesn't
even create an empty file). See write_scrollback_file for
available values.
new_window:
Open a new window. If the application isn't currently focused,
this will bring it to the front.
new_tab:
Open a new tab.
previous_tab:
Go to the previous tab.
next_tab:
Go to the next tab.
last_tab:
Go to the last tab (the one with the highest index)
goto_tab:
Go to the tab with the specific number, 1-indexed. If the tab number
is higher than the number of tabs, this will go to the last tab.
move_tab:
Moves a tab by a relative offset.
Adjusts the tab position based on `offset`. For example `move_tab:-1` for left, `move_tab:1` for right.
If the new position is out of bounds, it wraps around cyclically within the tab range.
toggle_tab_overview:
Toggle the tab overview.
This only works with libadwaita enabled currently.
new_split:
Create a new split in the given direction. The new split will appear in
the direction given. For example `new_split:up`. Valid values are left, right, up, down and auto.
goto_split:
Focus on a split in a given direction. For example `goto_split:up`.
Valid values are left, right, up, down, previous and next.
toggle_split_zoom:
zoom/unzoom the current split.
resize_split:
Resize the current split by moving the split divider in the given
direction. For example `resize_split:left,10`. The valid directions are up, down, left and right.
equalize_splits:
Equalize all splits in the current window
inspector:
Show, hide, or toggle the terminal inspector for the currently focused
terminal.
open_config:
Open the configuration file in the default OS editor. If your default OS
editor isn't configured then this will fail. Currently, any failures to
open the configuration will show up only in the logs.
reload_config:
Reload the configuration. The exact meaning depends on the app runtime
in use but this usually involves re-reading the configuration file
and applying any changes. Note that not all changes can be applied at
runtime.
close_surface:
Close the current "surface", whether that is a window, tab, split, etc.
This only closes ONE surface. This will trigger close confirmation as
configured.
close_tab:
Close the current tab, regardless of how many splits there may be.
This will trigger close confirmation as configured.
close_window:
Close the window, regardless of how many tabs or splits there may be.
This will trigger close confirmation as configured.
close_all_windows:
Close all windows. This will trigger close confirmation as configured.
This only works for macOS currently.
toggle_fullscreen:
Toggle fullscreen mode of window.
toggle_window_decorations:
Toggle window decorations on and off. This only works on Linux.
toggle_secure_input:
Toggle secure input mode on or off. This is used to prevent apps
that monitor input from seeing what you type. This is useful for
entering passwords or other sensitive information.
This applies to the entire application, not just the focused
terminal. You must toggle it off to disable it, or quit Ghostty.
This only works on macOS, since this is a system API on macOS.
toggle_quick_terminal:
Toggle the "quick" terminal. The quick terminal is a terminal that
appears on demand from a keybinding, often sliding in from a screen
edge such as the top. This is useful for quick access to a terminal
without having to open a new window or tab.
When the quick terminal loses focus, it disappears. The terminal state
is preserved between appearances, so you can always press the keybinding
to bring it back up.
To enable the quick terminally globally so that Ghostty doesn't
have to be focused, prefix your keybind with `global`. Example:
\```ini
keybind = global:cmd+grave_accent=toggle_quick_terminal
\```
The quick terminal has some limitations:
- It is a singleton; only one instance can exist at a time.
- It does not support tabs, but it does support splits.
- It will not be restored when the application is restarted
(for systems that support window restoration).
- It supports fullscreen, but fullscreen will always be a non-native
fullscreen (macos-non-native-fullscreen = true). This only applies
to the quick terminal window. This is a requirement due to how
the quick terminal is rendered.
See the various configurations for the quick terminal in the
configuration file to customize its behavior.
This currently only works on macOS.
toggle_visibility:
Show/hide all windows. If all windows become shown, we also ensure
Ghostty becomes focused. When hiding all windows, focus is yielded
to the next application as determined by the OS.
This currently only works on macOS.
quit:
Quit ghostty.
crash:
Crash ghostty in the desired thread for the focused surface.
WARNING: This is a hard crash (panic) and data can be lost.
The purpose of this action is to test crash handling. For some
users, it may be useful to test crash reporting functionality in
order to determine if it all works as expected.
The value determines the crash location:
- "main" - crash on the main (GUI) thread.
- "io" - crash on the IO thread for the focused surface.
- "render" - crash on the render thread for the focused surface.
```

## Testing
- Run `ghostty-dev +list-actions --docs` to verify the new output format
- Check generated _zig-out/share/ghostty/webdata/actions.mdx_ to ensure
all actions are properly documented
If a theme was not a file or a directory you could get a crash or a hang
(depending on platform) if the theme references a directory. This patch
also prevents attempts to load from other non-file sources.

This introduces a mechanism by which parsed config fields can be renamed
to maintain backwards compatibility. This already has a use case --
implemented in this commit -- for `background-blur-radius` to be renamed
to `background-blur`.
The remapping is comptime-known which lets us do some comptime
validation. The remap check isn't done unless no fields match which
means for well-formed config files, there's no overhead.
For future improvements:
- We should update our config help generator to note renamed fields.
- We could offer automatic migration of config files be rewriting them.
- We can enrich the value type with more metadata to help with
config gen or other tooling.
This commit fixes two issues with the `list-actions` command:
1. Ensures all actions are listed, including those without individual
documentation but sharing docs with related actions
2. Improves documentation formatting with proper indentation and grouping
When searching in the theme list (e.g., searching for "Snazzy"), some matching themes might be hidden due to incorrect window position handling.
This fix ensures all matching themes are visible by adjusting the window position logic.
macOS will create `.DS_Store` files in any directory it opens in Finder.
The `+list_themes` command would then list this file as a theme, and
attempt to preview it. `.DS_Store` is a binary file, and is silently
failing in the theme preview...I am on Linux and when I put a small
binary file in my user themes directory, I get a segfault. There is
something about the specific contents in `.DS_Store` that does not cause
this segfault, but lets us silently fail. We should investigate this
further - the issue is in `Config.loadFile` I believe.
In either case, we need to ignore `.DS_Store` so that it is not listed
as a theme.
Fixes: #3378
This adds a `+show-face` CLI action to show what font face Ghostty will
use to display a particular codepoint. The codepoint can either be
specified via a single integer or via UTF-8 encoded string.
Ghostty now has a release channel build configuration. Current valid
values are "tip" and "stable" but I imagine more will be added in the
future.
The release channel is inferred whether the version we specify with the
`-Dversion-string` build flag has a prerelease tag or not. If it does,
the release channel is "tip". If it doesn't, the release channel is
"stable".
This also adds a configuration to specify the release channel for
auto-updates for the macOS application.
Fixes#2747
I admit I don't fully understand this. But somehow, doing `var x: ?T =
undefined` in release fast mode makes `x` act as if its unset. I am
guessing since undefined does nothing to the memory, the memory layout
is such that it looks null for zeroed stack memory. This is a guess.
To fix this, I now initialize the type `T` and set it onto the optional
later. This commit also fixes an issue where calling `parseCLI` multiple
times on an optional would not modify the previous value if set.
