This fixes two things:
1. Surface focus state is not consistent with first responder state when
the search bar is open.
> Reproduce: Open search, switch to another app and back, observe the
cursor state of the surface.
> And after switching back, `cmd+shift+f` will close the search bar,
surface will become focused but not first responder, so it will not
accept any input
2. Command palette is not focused when built with Xcode 26.4 (26.3 works
fine).
> This is weird to me, because the tip (and built with 26.3) works fine.
I guess it's related to the SDK update? I couldn’t be sure what went
wrong, but dispatching it to the next loop works as previously.
> Also cleaned some previous checks when quickly open and reopen.
> This fix works great both with 26.4 and 26.3

Add a new Pager type that wraps output to an external pager program when
stdout is a TTY, following the same conventions as git. The pager
command is resolved from $PAGER, falling back to `less`. An empty $PAGER
disables paging. If the pager fails to spawn, we fall back to stdout.
Previously, +explain-config wrote directly to stdout with no paging,
which meant long help text would scroll by. Now output is automatically
piped through the user's preferred pager when running interactively. A
--no-pager flag is available to disable this.

### Summary
This PR implements a fix for:
https://github.com/ghostty-org/ghostty/discussions/10264
This allows the `macos-titlebar-style` setting `tabs` to behave the same
way other titlebar style options do with middle click handling.
### AI Disclosure
I used claude code (Sonnet 4.6) to identify the best place to start when
implementing this change, as well as for general Swift questions. The
code within this PR is written by me.
Fixes#11957
erasePage now updates page_serial_min when the first page is erased, and
asserts that only front or back pages are erased since page_serial_min
cannot represent serial gaps from middle erasure.
eraseRows can still technically destroy middle pages but no caller does
that today. We'll have to rethink this eventually.
Fixes#11957
erasePage now updates page_serial_min when the first page is erased,
and asserts that only front or back pages are erased since
page_serial_min cannot represent serial gaps from middle erasure.
To enforce this invariant at the API level, PageList.eraseRows is
now private. Two public wrappers replace it: eraseHistory always
starts from the beginning of history, and eraseActive takes a y
coordinate (with bounds assertion) and always starts from the top
of the active area. This makes middle-page erasure impossible by
construction.
The headers were not C++ compatible and would fail compiling before (see
https://github.com/ghostty-org/ghostty/discussions/11878). The only
reason is because our typedefs would conflict since we named them
identically.
This also adds a `c-vt-stream` example and a `cpp-vt-stream` example,
the latter primarily to verify we can build in C++ mode.
Add a cpp-vt-stream example that verifies libghostty headers compile
cleanly in C++ mode. The example is a simplified C++ port of
c-vt-stream.
The headers used the C idiom `typedef struct Foo* Foo` for opaque
handles, which is invalid in C++ because struct tags and typedefs
share the same namespace. Fix all 12 opaque handle typedefs across the
headers to use a distinct struct tag with an Impl suffix, e.g.
`typedef struct GhosttyTerminalImpl* GhosttyTerminal`. This is a
source-compatible change for existing C consumers since the struct
tags were never referenced directly.
If a `VERSION` file is present from our build root, prefer that as our
version source of truth over `build.zig.zon`. This file is automatically
created in source tarballs and will allow us to cut pre-release tarballs
of libghostty in particular (but affects all) that has a more specific
version than what can be in build.zig.zon.
This also adds the APIs necessary to extract this via the C API.
I started prepping for a separate libghostty version but not sure if
I'll wire that up in this PR yet or not...
Until gtk 4.20.1 trackpads have kinetic scrolling behavior regardless of
`Gtk.ScrolledWindow.kinetic_scrolling`. As a workaround, set
EventControllerScroll.kinetic to false on all controllers.
`observeControllers()` has this warning:
> Calling this function will enable extra internal bookkeeping to track
controllers and emit signals on the returned listmodel. It may slow down
operations a lot.
> Applications should try hard to avoid calling this function because of
the slowdowns.
but judging from the
[source](5301a91f1c/gtk/gtkwidget.c (L12375-L12383))
this is a one time penalty since we free the result immediately
afterwards.

Zed + Opus 4.5 generated the first pass, but it missed freeing the
result of `observeControllers()` and conveniently binding
`scrolled_window` to the blueprint. Figuring out what was going on also
took a lot of [human

The argument iterator's .next() method returns a transient slice of the
command line buffer so we need to make our own copies of these values to
avoid referencing stale memory.
Read the app version from a VERSION file in the build root,
trimming whitespace, and fall back to build.zig.zon if the file
is not present. This allows source tarballs to carry a VERSION
file as the source of truth for the version string.
Add version (std.SemanticVersion) to the terminal build options so that
the terminal module has access to the application version at comptime.
The add() function breaks it out into version_string, version_major,
version_minor, version_patch, and version_build terminal options.
On the C API side, five new GhosttyBuildInfo variants expose these
through ghostty_build_info(). String values use GhosttyString; numeric
values use size_t. When no build metadata is present, version_build
returns a zero-length string.
The c-vt-build-info example is updated to query and print all version
fields.

If `$EDITOR` or `$VISUAL` contained arguments, not just the path to an
editor (e.g. `zed --new`) `+edit-config` would fail because we were
treating the whole command as a path. Instead, wrap the command with
`/bin/sh -c <command>` so that the shell can separate the path from the
arguments.

Replace hardcoded locale.h constants and extern function declarations
with build-system TranslateC, following the same pattern as pty.c.
This fixes LC_ALL being hardcoded to 6 (the musl/glibc implementation
value), which is implementation-defined and differs on Windows MSVC
(where LC_ALL is 0), causing `setlocale()` to crash with an invalid
parameter error.
## Changes
- Added `src/os/locale.c` — includes `locale.h` for TranslateC
- Added TranslateC step in `src/build/SharedDeps.zig` (same pattern as
pty.c)
- Replaced hardcoded constants and extern declarations in
`src/os/locale.zig` with `@import("locale-c")`
