Fixes#1183
I'm not sure why the original logic was there. When I translated the
original test cases to shell and ran them in xterm, they did NOT match
what Ghostty expected. This updates the tests to match xterm and removes
this case. We can add back in more tests if/when we figure out under
what scenario this original logic was correct (if it ever was).
PR #1168 introduced a loop to kill all children. The `waitpid` call is
issued with the NOHANG flag, which means it returns immediately if no
child has exited. This has the effect that we can repeatedly run through
this loop making this syscall, flooding the system with calls and not
getting timely responses. On my system, this caused Ghostty to take ~30
seconds to close. In my attempts to debug, I added logging to the loop
which resolved the issue. To find out why, I added a loop counter and
found the loop would run > 70 million cycles while trying to close. By
adding logging, I introduced just enough delay in the loop cycle to
prevent whatever flooding of syscalls was happening. This reduced the
loop counter to ~2 cycles before closing.
Add a small delay to prevent syscall flooding.
Fixes#497
This commit resolves two bugs:
First, if a surface is created and destroyed too quickly, the child
process may not have called `setsid` yet (to set the process group). In
this case, `getpgid` returns Ghostty's process group and we were killing
ourselves. We now detect we're about to kill ourselves and wait for our
child to be ready to be killed.
Second, if the child calls setsid but is in the process of execve when
we send a killpg, then the child will be killed but any newly spawned
grandchildren will remain alive. To fix this, we moved the waitpid call
into a kill loop so we can repeatedly kill our child if we detect any
grandchildren are still alive.
Fixes#1159
The cursor position is an "active" coordinate (defined at the top of
Screen.zig), but our resize was treating it as a "viewport" coordinate.
This adds a new configuration `grapheme-width-method` to change the
default behavior that Ghostty uses to calculate grapheme width. The
default value is `unicode` which is identical to setting mode 2027.
**IMPORTANT:** This changes the default Ghostty behavior to be fully
grapheme-aware including ZWJs, VS15, VS16. This may cause issues with
some legacy programs and shells.
I've changed my mind that this should become the default because enough
people use emojis now that I've found in the beta program there are more
issues reported about "incorrect emoji width" than any possibly desync
issues. We'll see.
For legacy programs, this can still be set to `grapheme-width-method =
wcswidth`.

Following up on #1145, this changes middle-click behavior on MacOS to
always paste from the system clipboard. This does not alter any of the
selection behavior, i.e. default behavior is to allow paste, but you
still need to manually copy. MacOS users still need to enable
"copy-on-select = clipboard" for that respective functionality.
From #1132, our resources dir is now someting like `/usr/share/ghostty`,
but GTK icons always go into `/usr/share/icons`. This does a basename on
the resources dir to set the correct directory.
Fixes#1146
I can't remember why we did this before. The comment in question makes
sense if we were trying to set cur to infinity but doesn't make sense to
me why we'd change max. Removing this doesn't seem to cause any issues
so lets give it a shot.
Installing resources directly under ${prefix}/share causes conflicts
with other packages. This will become more problematic whenever Ghostty
is opened and becomes packaged in distributions.
Instead, install all resources under a "ghostty" subdirectory (i.e.
${prefix}/share/ghostty). This includes themes, shell integration, and
terminfo files.
Only "/usr/share" style paths use the "ghostty" subdirectory. On macOS,
Ghostty is already isolated within its app bundle, and if
$GHOSTTY_RESOURCES_DIR is set then we assume that points to the actual
resources dir (without needing to append "ghostty" to it).
Commit 5e473ebd ("terminfo: add additional entries, fix smkx/rmkx")
added entries `xr` and `rv`, but without proper escaping of the
backslashes. This commit adds the extras. Output of `infocmp` now
matches foot, kitty, et al.
Fixes#1047
This resets the IME state only if we were previously in a composing
state. I did not realize that IME state also included non-composing
state that we want to preserve, such as the next quotation direction
in the case of chinese. i.e. `“` vs `”`.
I'm not fully sure that this is the right logic, but previous pre-edit
states such as in Japanese appear to still work and this fixes Chinese
quotation marks.
This adds Powerline rendering for the trapezoid characters (E0D2 and
E0D4).
This is the last of the Powerline additions for now. These are the
shapes that 1) render the most egregiously with stock fonts (off-center,
bleeding background, visible gaps), and 2) are simple enough to be
rendered without resorting to more complex measures like embedding SVG.
