This changes the way Ghostty assigns itself and subprocesses to
cgroups and how resource controls are applied.
* Ghostty itself no longer modifies it's own cgroup or moves itself
to a transient scope. To modify the main Ghostty process' resource
controls ensure that you're launching Ghostty with a systemd unit and
use the standard systemd methods for overriding and applying changes
to systemd units.
* If configured (on by default), the process used to run your command
will be moved to a transient systemd scope after it is forked from
Ghostty but before the user's command is executed. Resource controls
will be applied to the transient scope at this time. Changes to
the `linux-cgroup*` configuration entries will not alter existing
commands. If changes are made to the `linux-cgroup*` configuration
entries commands will need to be relaunched. Resource limits can also
be modified after launch outside of Ghostty using systemd tooling. The
transient scope name can be shown by running `systemctl --user whoami`
in a shell running inside Ghostty.

The `cursor` shell feature always used a blinking bar (beam), often to
the surprise of users who set `cursor-style-blink = false`.
This change extends our GHOSTTY_SHELL_FEATURES format to include either
`cursor:blink` (default) or `cursor:steady` based on cursor-style-blink
when the `cursor` feature is enabled, and all shell integrations have
been updated to use that additional information to choose the DECSCUSR
cursor value (5=blinking bar, 6=steady bar).
I also considered passing a DECSCUSR value in GHOSTTY_SHELL_FEATURES
(e.g. `cursor:5`). This mostly worked well, but zsh also needs the blink
state on its own for its block cursor. We also don't support any other
shell feature cursor configurability (e.g. the shape), so this was an
over generalization.
This does change the behavior for users who like the blinking bar in the
shell but have `cursor-blink-style = false` for other reasons. We could
provide additional `cursor` shell feature configurability (e.g.
`cursor:blink` in `shell-integration-features`), but I'll propose that
as its own change.

**AI Disclosure:** I did a lot of rubber ducking with Claude Code while
trying out various ideas. It was particularly useful for this kind of
feature because I could try out one thing and have it evaluate the
impact on all of the shell integration scripts at once.
When a user renames a surface via "Change Terminal Title" and then
uses copy_title_to_clipboard, the raw terminal title was copied
instead of the custom name.
This adds a new `copy_title` apprt action so each platform resolves
the effective title (user override or terminal-set) before copying
to clipboard.

The reporting of color scheme was handled asynchronously by queuing a
handler in the surface. This could lead to race conditions where the DSR
is reported after subsequent VT sequences.
Fixes#5922
- Change all codepoint types from u32 to u21 to align with Zig stdlib
- Update ArrayList to use Zig 0.15 unmanaged pattern (.empty)
- Remove unnecessary @intCast when encoding UTF-8
- Fix formatEntry to use stack-allocated buffer
Refactor the selection-word-chars implementation to parse UTF-8 boundary
characters once during config initialization instead of on every selection
operation.
Changes:
- Add SelectionWordChars type that stores pre-parsed []const u32 codepoints
- Parse UTF-8 to codepoints in parseCLI() during config load
- Remove UTF-8 parsing logic from selectWord() hot path (27 lines removed)
- Remove arbitrary 64-character buffer limit
- Update selectWord() and selectWordBetween() to accept []const u32
- Update DerivedConfig to store codepoints directly
- Update all tests to use codepoint arrays
Benefits:
- No runtime UTF-8 parsing overhead on every selection
- No arbitrary character limit (uses allocator instead)
- Cleaner separation of concerns (config handles parsing, selection uses data)
- Better performance in selection hot path
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

This is a solution for #2107.
When a user right-clicks, and there's no existing selection, the
existing behavior is to try to select the word under the cursor:
3548acfac6/src/Surface.zig (L3740-L3742)
This PR tweaks that behavior _slightly_: If there's a link under our
cursor, as determined by `linkAtPos`, select the link (to copy with the
right-click context menu). Otherwise, select the word as before.
As noted in #2107, this matches the behavior of iTerm and Gnome
Terminal.
It's worth noting that `linkAtPos` already does the right thing in terms
of checking the links from config and their highlight/hover states
(modified by Ctrl or Super depending on platform).
3548acfac6/src/Surface.zig (L3896-L3901)
It also therefore respects `link-url` from config.
3548acfac6/src/config/Config.zig (L3411-L3416)
By using `linkAtPos`, we get all that behavior for free. In practical
terms, that means:
- If I'm holding Ctrl so a link is underlined and I right click on it,
it selects the underlined link.
- If I'm not holding Ctrl and I right click on a link that is not
underlined, it selects the word as before.
- This behavior respects per-platform key bindings and user config
settings.
`linkAtPos` requires that the render state mutex is held. I believe it's
safe to call because we're inside a block holding the mutex:
3548acfac6/src/Surface.zig (L3702-L3704)
**AI Disclosure:** I used Gemini CLI to help me with this PR because
while I have many years of programming experience, this is my first time
writing Zig. I prototyped a couple different approaches with AI before
landing on this one, so AI generated various prototypes and I chose the
final imlementation. I've verified that my code compiles and works as
intended.
When double-clicking text, first check if the position is part of a URL
using the default URL regex pattern. If a URL is detected, select the
entire URL instead of just the word.
This follows the feedback from PR #2324 to modify the selection behavior
rather than introducing a separate selectLink function. The implementation
uses the existing URL regex from config/url.zig which already handles
various URL schemes (http, https, ftp, ssh, etc.) and file paths.
The URL detection runs before the normal word selection, falling back to
selectWord if no URL is found at the clicked position.
Adds the `selection_for_search` action, with Cmd+E keybind by default.
This action inputs the currently selected text into the search
field without changing focus, matching standard macOS behavior.
End the currently active key sequence, if any, and flush the
keys up to this point to the terminal, excluding the key that
triggered this action.
For example: `ctrl+w>escape=end_key_sequence` would encode
`ctrl+w` to the terminal and exit the key sequence.
Normally, an invalid sequence will reset the key sequence and
flush all data including the invalid key. This action allows
you to flush only the prior keys, which is useful when you want
to bind something like a control key (`ctrl+w`) but not send
additional inputs.
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 adds some new special case handling for key sequences when an
unbound keyboard input is received. If the current keybinding set scope
(i.e. active tables) has a `catch_all` binding that would `ignore`
input, then the entire key sequence is dropped.
Normally, when an unbound key sequence is received, Ghostty encodes it
and sends it to the running program.
This special behavior is useful for things like Vim mode which have `g>g`
to scroll to top, and a `catch_all=ignore` to drop all other input. If
the user presses `g>h` (unbound), you don't want `gh` to show up in your
terminal input, because the `catch_all=ignore` indicates that the user
wants that mode to drop all unbound input.
Two unrelated changes to polish key tables:
1. Key tables should be reset (deactivated) when teh config is reloaded.
This matches the behavior of key sequences as well, which are reset
on config reload.
2. A maximum number of active key tables is now enforced (8).
This prevents a misbehaving config from consuming too much memory
by activating too many key tables. This is an arbitrary limit we
can adjust later if needed.
