Fixes #4800, supercedes #5995
This is a rewrite of #5995 (though the solution is mostly the same since
this is pretty straightforward). The main difference is the rebase on
the new mouse handling we've had since, and I also continue to update
the selection clipboard on non-left-mouse events.

Introduces host resources directory as a new concept: A directory
containing application resources that can only be accessed from the host
operating system. This is significant for sandboxed application runtimes
like Flatpak where shells spawned on the host should have access to
application resources to enable integrations.
Alongside this, apprt is now allowed to override the resources lookup
logic.

This commit is very large, representing about a month of work with many
interdependent changes that don't separate cleanly in to atomic commits.
The main change here is unifying the renderer logic to a single generic
renderer, implemented on top of an abstraction layer over OpenGL/Metal.
I'll write a more complete summary of the changes in the description of
the PR.

Related to #7468
This changes the behavior of "ignore". Previously, Ghostty would
consider "ignore" actions consumed but do nothing. They were like a
black hole. Now, Ghostty returns `ignored` which lets the apprt forward
the event to the OS/GUI.
This enables keys that would otherwise be pty-encoded to be processed
later, such as for GTK to show the GTK inspector.
|
|
As of Zig 0.14.0, `@splat` can be used for array types, which eliminates
a lot of redundant syntax and makes things generally cleaner.
I've explicitly avoided applying this change in the renderer files for
now since it would just create rebasing conflicts in my renderer rework
branch which I'll be PR-ing pretty soon.

|
|
Removes a lot of repeated code and makes the test cases easier to
understand at a glance.
|
|
Adds many test cases for expected behavior of the selection logic, this
will allow changes to be made more confidently in the future without
fear of regressions.
|
|
This logic is cleaner and produces better behavior when selecting by
dragging the mouse outside the bounds of the surface, previously when
doing this on the left side of the surface selections would include the
first cell of the next row, this is no longer the case.
This introduces methods on PageList.Pin which move a pin left or right
while wrapping to the prev/next row, or clamping to the ends of the row.
These need unit tests.

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)

This adds a keybinding and apprt action for #7237.

This PR implements a more lightweight alternative to #5326 that contains
features that I personally think Just Make Sense for the bell.
No configs, no GStreamer stuff, just sane defaults to get us started.

Fixes #7077
This follows pretty standard behavior across native or popular applications
on both platforms macOS and Linux. The basic behavior is that if you
do a mouse down event and then drag the mouse beyond the current
character, then any mouse up actions are canceled (beyond emiting the
event itself).
This fixes a specific scenario where you could do the following:
1. Click anywhere (mouse down)
2. Drag over a valid link
3. Press command/control (to activate the link)
4. Release the mouse button (mouse up)
5. The link is triggered
Now, step 3 and step 5 do not happen. Links are not even highlighted in
this scenario. This matches iTerm2 on macOS which has a similar
command-to-activate-links behavior.

This introduces a syntax for `command` and `initial-command` that allows
the user to specify whether it should be run via `/bin/sh -c` or not.
The syntax is a prefix `direct:` or `shell:` prior to the command,
with no prefix implying a default behavior as documented.
Previously, we unconditionally ran commands via `/bin/sh -c`, primarily
to avoid having to do any shell expansion ourselves. We also leaned on
it as a crutch for PATH-expansion but this is an easy problem compared
to shell expansion.
For the principle of least surprise, this worked well for configurations
specified via the config file, and is still the default. However, these
configurations are also set via the `-e` special flag to the CLI, and it
is very much not the principle of least surprise to have the command run via
`/bin/sh -c` in that scenario since a shell has already expanded all the
arguments and given them to us in a nice separated format. But we had no
way to toggle this behavior.
This commit introduces the ability to do this, and changes the defaults
so that `-e` doesn't shell expand. Further, we also do PATH lookups
ourselves for the non-shell expanded case because thats easy (using
execvpe style extensions but implemented as part of the Zig stdlib). We don't
do path expansion (e.g. `~/`) because thats a shell expansion.
So to be clear, there are no two polar opposite behavioes here with
clear semantics:
1. Direct commands are passed to `execvpe` directly, space separated.
This will not handle quoted strings, environment variables, path
expansion (e.g. `~/`), command expansion (e.g. `$()`), etc.
2. Shell commands are passed to `/bin/sh -c` and will be shell expanded
as per the shell's rules. This will handle everything that `sh`
supports.
In doing this work, I also stumbled upon a variety of smaller
improvements that could be made:
- A number of allocations have been removed from the startup path that
only existed to add a null terminator to various strings. We now
have null terminators from the beginning since we are almost always
on a system that's going to need it anyways.
- For bash shell integration, we no longer wrap the new bash command
in a shell since we've formed a full parsed command line.
- The process of creating the command to execute by termio is now unit
tested, so we can test the various complex cases particularly on
macOS of wrapping commands in the login command.
- `xdg-terminal-exec` on Linux uses the `direct:` method by default
since it is also assumed to be executed via a shell environment.

Fixes #6821
UTF8 translation using KeymapDarwin requires a buffer and the buffer was
stack allocated in the coreKeyEvent call and returned from the function.
We need the buffer to live longer than this.
Long term, we're removing KeymapDarwin (there is a whole TODO comment in
there about how to do it), but this fixes a real problem today.

This adds a CI test to ensure that all Zig files are properly formatted.
This avoids unrelated diff noise in future PRs.

Some wheel mice are capable of reporting fractional wheel ticks. These
mice don't necessarily report a corresponding precision scroll start
event, at least in Wayland + GTK. We can treat all discrete (ie
non-precision) events as the number of wheel ticks - for wheel mice,
yoff will be "1.0" per tick, while precision wheel mice may report
fractional values. This unifies handling of scroll events by normalizing
all events to "pixels to scroll".
We now report `mouse-scroll-multiplier` wheel or arrow events per wheel
tick (or per accumulated cell height). This means that applications
which subscribe to mouse button events will receive (by default) three
wheel events per wheel tick. For precision scrolls, they will receive
one wheel tick per line of scroll. In my opinion, this provides the best
user experience while also allowing customization of how much a
wheel tick should scroll

For *some* reason we have a binding for close_window but it merely closes
the surface and not the entire window. That is not only misleading but
also just wrong. Now we make a separate apprt action for close_window
that would make it show a close confirmation prompt identical to as if
the user had clicked the (X) button on the window titlebar.
|
|
Precision scrolls don't require a multiplier to behave nicely. However,
wheel scrolls feel extremely slow without one. We apply the multiplier
to wheel scrolls only
|
|
When we report mouse scroll wheel events, they should not be multiplied.
Refactor the scrollCallback to only use a multiplier for viewport or
alternate scroll reports.

scrolls
Calculate the scroll amount for non-precision scrolls as a direct
multiple of yoff. This fixes an issue where Ghostty sends scroll wheel
events (or arrow keys if in alternate scroll mode) that are variable,
dependent on the screen size. I checked multiple terminals, and each
responds to a single wheel click by sending only a single wheel / arrow
key - independent of screen size.
```sh
printf "\x1b[?1049h"
printf "\x1b[?1007h"
cat -v
```
Using the above procedure, with varying screen sizes:
```
# 50% Screen height
| terminal | arrows keys sent| wheels events sent|
|------------|-----------------|-------------------|
| alacritty | 3 | 1 |
| foot | 3 | 1 |
| xterm | 5 | 1 |
| kitty | 3 | 1 |
| ghostty | 2 | 2 |
# 100% Screen height
| terminal | arrows keys sent| wheels events sent|
|------------|-----------------|-------------------|
| alacritty | 3 | 1 |
| foot | 3 | 1 |
| xterm | 5 | 1 |
| kitty | 5 | 1 |
| ghostty | 3 | 3 |
```
Both ghostty and kitty scale the number of arrow keys sent in proportion
to the screen size. However, when mouse reporting is on, only ghostty
does this.
This commit makes Ghostty behave like foot, and more generally removes
the dependence on screen size.

This implements the keybind/action portion of #5974 so that this can
have a binding and so that other apprts can respond to this and
implement it this way.

As noted in the comments, this is so that apprt's can always know what
the default size of a window would be so they can utilize this for
"return to default size" actions.
The initial size shouldn't be treated as a "resize" event and was
already documented as such. Prior to this commit the docs already noted
that the initial size may be sent multiple times but only the first time
during initialization should be used as a resize.
Therefore, this shouldn't impact prior behavior. I've verified this with
the apprts.

Fixes #5257
Specify environment variables to pass to commands launched in a terminal
surface. The format is `env=KEY=VALUE`.
`env = foo=bar`
`env = bar=baz`
Setting `env` to an empty string will reset the entire map to default
(empty).
`env =`
Setting a key to an empty string will remove that particular key and
corresponding value from the map.
`env = foo=bar`
`env = foo=`
will result in `foo` not being passed to the launched commands.
Setting a key multiple times will overwrite previous entries.
`env = foo=bar`
`env = foo=baz`
will result in `foo=baz` being passed to the launched commands.
These environment variables _will not_ be passed to commands run by Ghostty
for other purposes, like `open` or `xdg-open` used to open URLs in your
browser.

Finishes #378
Supercedes #4159
This adds a new enum value for `macos-non-native-fullscreen`:
`padded-notch`. This value will add padding to the top of the window to
account for the notch on applicable devices while still hiding the
menu.
This value is preferred over "visible-menu" by some people because for
screens without a notch, the window will take up the full height.
The plan in the future is that we may color the padded area when a notch
is present. In this commit it appears as transparent.

Supercedes #5726
|
|
This is to facilitate the `performable:` prefix on keybinds that are
implemented using app runtime actions.
|
|
`WINDOWID` is the conventional environment variable for scripts that
want to know the X11 window ID of the terminal, so that it may call
tools like `xprop` or `xdotool`. We already know the window ID for
window protocol handling, so we might as well throw this in for
convenience.

As recommended in
https://github.com/ghostty-org/ghostty/pull/4927#issuecomment-2585003934,
adds a config option `maximize` for starting a window in a maximized
state in terms of window properties. Also adds a `toggle_maximize`
keybind to allow users to manually toggle this feature on and off.
It might make more sense to make this an optional config value so that
we don't toggle the state off if the WM already handles that for us, but
I'll let a reviewer decide.
Closes https://github.com/ghostty-org/ghostty/issues/4646
