Add new `selection-word-chars` config option to customize which characters
mark word boundaries during text selection operations (double-click, word
selection, etc.). Similar to zsh's WORDCHARS environment variable, but
specifies boundary characters rather than word characters.
Default boundaries: ` \t'"│`|:;,()[]{}<>$`
Users can now customize word selection behavior, such as treating
semicolons as part of words or excluding periods from boundaries:
selection-word-chars = " \t'\"│`|:,()[]{}<>$"
Changes:
- Add selection-word-chars config field with comprehensive documentation
- Modify selectWord() and selectWordBetween() to accept boundary_chars parameter
- Parse UTF-8 boundary string to u32 codepoints at runtime
- Update all call sites in Surface.zig and embedded.zig
- Update all test cases to pass boundary characters
Make clipboardRequest return bool to indicate whether the action could
be performed. For paste requests, synchronously check if the clipboard
contains text formats before starting the async read.
This allows 'performable:paste_from_clipboard' keybinds to pass through
when the clipboard contains non-text content (e.g., images), enabling
terminal applications to handle their own clipboard reading.
Changes:
- Surface.startClipboardRequest now returns bool
- paste_from_clipboard/paste_from_selection actions return the result
- GTK apprt checks clipboard formats synchronously before async read
- Embedded apprt always returns true (can't check synchronously)
- All other call sites discard the return value with _
This is a regression introduced when we added macOS support for custom
entries. I mistakingly thought that only custom entries were in the
config, but we do initialize it with all!
This removes `launched-from` entirely and moves our `gtk-single-instance`
detection logic to assume true unless we detect CLI instead of assume
false unless we detect desktop/dbus/systemd.
The "assume true" scenario for single instance is desirable because
detecting a CLI instance is much more reliable.
Removing `launched-from` fixes an issue where we had a
difficult-to-understand relationship between `launched-from`,
`gtk-single-instance`, and `initial-window`. Now, only
`gtk-single-instance` has some hueristic logic. And `initial-window`
ALWAYS sends a GTK activation signal regardless of single instance or
not.
As a result, we need to be explicit in our systemd, dbus, desktop files
about what we want Ghostty to do, but everything works as you'd mostly
expect.
Now, if you put plain old `ghostty` in your terminal, you get a new
Ghostty instance. If you put it anywhere else, you get a GTK single
instance activation call (either creates a first instance or opens a new
window in the existing instance). Works for launchers and so on.
Detecting the launch source frequently failed because various launchers
fail to sanitize the environment variables that Ghostty used to
detect the launch source. For example, if your desktop environment was
launched by `systemd`, but your desktop environment did not sanitize the
`INVOCATION_ID` or the `JOURNAL_STREAM` environment variables, Ghostty
would assume that it had been launched by `systemd` and behave as such.
This led to complaints about Ghostty not creating new windows when users
expected that it would.
To remedy this, Ghostty no longer does any detection of the launch
source. If your launch source is something other than the CLI, it must
be explicitly speciflied on the CLI. All of Ghostty's default desktop
and service files do this. Users or packagers that create custom desktop
or service files will need to take this into account.
On GTK, the `desktop` setting for `gtk-single-instance` is replaced with
`detect`. `detect` behaves as `gtk-single-instance=true` if one of the
following conditions is true:
1. If no CLI arguments have been set.
2. If `--launched-from` has been set to `desktop`, `dbus`, or `systemd`.
Otherwise `detect` behaves as `gtk-single-instance=false`.
Fixes#2473
This commit changes `ghostty_surface_ime_point` to return a full rect
with the width/height calculated for the preedit.
The `firstRect` function, which calls `ghostty_surface_ime_point` was
previously setting the width/height to zero. macOS didn't like this. We
then changed it to just hardcode it to width/height of one cell. This
worked but made it so the IME cursor didn't follow the preedit.
This is a tiny addon from the recent gtk-ng work. We've moved redraw
requests into the apprt action system (the `render` action). I waited
until I had my macOS machine to verify that this fix could work. We can
now remove this completely.
We can probably remove the redraw inspector API too at some point but
I'm not there yet with the GTK backend so I'll just wait on it.
Instead of using @hasDecl, use a performAction-stype API. The C
interface for interfacing with macOS (or any other apprt where Ghostty
is embedded) is unfinished.
This makes it so `zig build run` can take arguments such as
`--config-default-files=false` or any other configuration. Previously,
it only accepted commands such as `+version`.
Incidentally, this also makes it so that the app in general can now take
configuration arguments via the CLI if it is launched as a new instance
via `open`. For example:
open -n Ghostty.app --args --config-default-files=false
This previously didn't work. This is kind of cool.
To make this work, the libghostty C API was modified so that
initialization requires the CLI args, and there is a new C API to try to
execute an action if it was set.
This deletes the GLFW apprt from the Ghostty codebase.
The GLFW apprt was the original apprt used by Ghostty (well, before
Ghostty even had the concept of an "apprt" -- it was all just a single
application then). It let me iterate on the core terminal features,
rendering, etc. without bothering about the UI. It was a good way to get
started. But it has long since outlived its usefulness.
We've had a stable GTK apprt for Linux (and Windows via WSL) and a
native macOS app via libghostty for awhile now. The GLFW apprt only
remained within the tree for a few reasons:
1. Primarily, it provided a faster feedback loop on macOS because
building the macOS app historically required us to hop out of the
zig build system and into Xcode, which is slow and cumbersome.
2. It was a convenient way to narrow whether a bug was in the
core Ghostty codebase or in the apprt itself. If a bug was in both
the glfw and macOS app then it was likely in the core.
3. It provided us a way on macOS to test OpenGL.
All of these reasons are no longer valid. Respectively:
1. Our Zig build scripts now execute the `xcodebuild` CLI directly and
can open the resulting app, stream logs, etc. This is the same
experience we have on Linux. (Xcode has always been a dependency of
building on macOS in general, so this is not cumbersome.)
2. We have a healthy group of maintainers, many of which have access
to both macOS and Linux, so we can quickly narrow down bugs
regardless of the apprt.
3. Our OpenGL renderer hasn't been compatible with macOS for some time
now, so this is no longer a useful feature.
At this point, the GLFW apprt is just a burden. It adds complexity
across the board, and some people try to run Ghostty with it in the real
world and get confused when it doesn't work (it's always been lacking in
features and buggy compared to the other apprts).
So, it's time to say goodbye. Its bittersweet because it is a big part
of Ghostty's history, but we've grown up now and it's time to move on.
Thank you, goodbye.
(NOTE: If you are a user of the GLFW apprt, then please fork the project
prior to this commit or start a new project based on it. We've warned
against using it for a very, very long time now.)
Besides avoiding copying, this allows consumers to choose to allocate
these structs on the stack or to allocate on the heap. It also gives the
apprt.App a stable pointer sooner in the process.
Fixes#7647
See #7647 for context. This commit works by extending the `input` work
introduced in #7652 to libghostty so that the macOS can take advantage
of it. At that point, its just the macOS utilizing `input` in order to
set the command and `exit` up similar to Terminal and iTerm2.
Related to #7433
This extracts our "launched from desktop" logic into a config option.
The default value is detection using the same logic as before, but now
this can be overridden by the user.
This also adds the systemd and dbus activation sources from #7433.
There are a number of reasons why we decided to do this:
1. It automatically gets us caching since the configuration is only
loaded once (per reload, a rare occurrence).
2. It allows us to override the logic when testing. Previously, we
had to do more complex environment faking to get the same
behavior.
3. It forces exhaustive switches in any desktop handling code, which
will make it easier to ensure valid behaviors if we introduce new
launch sources (as we are in #7433).
4. It lowers code complexity since callsites don't need to have N
`launchedFromX()` checks and can use a single value.
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)
