Open a + [discussion in the "Vouch Request"](https://github.com/ghostty-org/ghostty/discussions/new?category=vouch-request) + category describing what you want to change and why. Follow the template. +2. Keep it concise +3. Write in your own voice, don't have an AI write this +4. A maintainer will comment `!vouch` if approved +5. Once approved, you can submit PRs + +If you aren't vouched, any pull requests you open will be +automatically closed. This system exists because open source works +on a system of trust, and AI has unfortunately made it so we can no +longer trust-by-default because it makes it too trivial to generate +plausible-looking but actually low-quality contributions. + +## Contributors Prior to the Vouch System + +If you contributed to Ghostty prior to the introduction +of the vouch system and wish to continue contributing, you were not +automatically added to the [list of vouched users](.github/VOUCHED.td). You will need to follow the same +process as a first-time contributor to be vouched. + +## Denouncement System + +If you repeatedly break the rules of this document or repeatedly +submit low quality work, you will be **denounced.** This adds your +username to a public list of bad actors who have wasted our time. All +future interactions on this project will be automatically closed by +bots. + +The denouncement list is public, so other projects who trust our +maintainer judgement can also block you automatically. + +## Quick Guide + +### I'd like to contribute + +[All issues are actionable](#issues-are-actionable).

Instead, we use GitHub +[discussions](https://github.com/ghostty-org/ghostty/discussions) for that. +Once a discussion reaches a point where a well-understood, actionable +item is identified, it is moved to the issue tracker. **This pattern +makes it easier for maintainers or contributors to find issues to work on +since _every issue_ is ready to be worked on.** + +If you are experiencing a bug and have clear steps to reproduce it, please +open an issue. If you are experiencing a bug but you are not sure how to +reproduce it or aren't sure if it's a bug, please open a discussion. +If you have an idea for a feature, please open a discussion. + +### Pull Requests Implement an Issue + +Pull requests should be associated with a previously accepted issue. +**If you open a pull request for something that wasn't previously discussed,** +it may be closed or remain stale for an indefinite period of time. I'm not +saying it will never be accepted, but the odds are stacked against you. + +Issues tagged with "feature" represent accepted, well-scoped feature requests. +If you implement an issue tagged with feature as described in the issue, your +pull request will be accepted with a high degree of certainty. + +> [!NOTE] +> +> **Pull requests are NOT a place to discuss feature design.** Please do +> not open a WIP pull request to discuss a feature.

On all platforms, logging to +`stderr` is available. Depending on the platform and how Ghostty was launched, +logs sent to `stderr` may be stored by the system and made available for later +retrieval. + +On Linux if Ghostty is launched by the default `systemd` user service, you can use +`journald` to see Ghostty's logs: `journalctl --user --unit app-com.mitchellh.ghostty.service`. + +On macOS logging to the macOS unified log is available and enabled by default. +Use the system `log` CLI to view Ghostty's logs: `sudo log stream --level debug --predicate 'subsystem=="com.mitchellh.ghostty"'`. + +Ghostty's logging can be configured in two ways. The first is by what +optimization level Ghostty is compiled with. If Ghostty is compiled with `Debug` +optimizations debug logs will be output to `stderr`. If Ghostty is compiled with +any other optimization the debug logs will not be output to `stderr`. + +Ghostty also checks the `GHOSTTY_LOG` environment variable. It can be used +to control which destinations receive logs. Ghostty currently defines two +destinations: + +- `stderr` - logging to `stderr`. +- `macos` - logging to macOS's unified log (has no effect on non-macOS platforms). + +Combine values with a comma to enable multiple destinations. Prefix a +destination with `no-` to disable it. Enabling and disabling destinations +can be done at the same time. Setting `GHOSTTY_LOG` to `true` will enable all +destinations. Setting `GHOSTTY_LOG` to `false` will disable all destinations. + +## Linting + +### Prettier + +Ghostty's docs and resources (not including Zig code) are linted using +[Prettier](https://prettier.io) with out-of-the-box settings. A Prettier CI +check will fail builds with improper formatting. Therefore, if you are +modifying anything Prettier will lint, you may want to install it locally and +run this from the repo root before you commit: + +``` +prettier --write . +``` + +Make sure your Prettier version matches the version of Prettier in [devShell.nix](https://github.com/ghostty-org/ghostty/blob/main/nix/devShell.nix). + +Nix users can use the following command to format with Prettier: + +``` +nix develop -c prettier --write . +``` + +### Alejandra + +Nix modules are formatted with [Alejandra](https://github.com/kamadorueda/alejandra/). An Alejandra CI check +will fail builds with improper formatting. + +Nix users can use the following command to format with Alejandra: + +``` +nix develop -c alejandra . +``` + +Non-Nix users should install Alejandra and use the following command to format with Alejandra: + +``` +alejandra . +``` + +Make sure your Alejandra version matches the version of Alejandra in [devShell.nix](https://github.com/ghostty-org/ghostty/blob/main/nix/devShell.nix). + +### ShellCheck + +Bash scripts are checked with [ShellCheck](https://www.shellcheck.net/) in CI. + +Nix users can use the following command to run ShellCheck over all of our scripts: + +``` +nix develop -c shellcheck \ + --check-sourced \ + --severity=warning \ + $(find . \( -name "*.sh" -o -name "*.bash" \) -type f ! -path "./zig-out/*" ! -path "./macos/build/*" ! -path "./.git/*" | sort) +``` + +Non-Nix users can [install ShellCheck](https://github.com/koalaman/shellcheck#user-content-installing) and then run: + +``` +shellcheck \ + --check-sourced \ + --severity=warning \ + $(find . \( -name "*.sh" -o -name "*.bash" \) -type f ! -path "./zig-out/*" ! -path "./macos/build/*" ! -path "./.git/*" | sort) +``` + +### SwiftLint + +Swift code is linted using [SwiftLint](https://github.com/realm/SwiftLint). A +SwiftLint CI check will fail builds with improper formatting. Therefore, if you +are modifying Swift code, you may want to install it locally and run this from +the repo root before you commit: + +``` +swiftlint lint --fix +``` + +Make sure your SwiftLint version matches the version in [devShell.nix](https://github.com/ghostty-org/ghostty/blob/main/nix/devShell.nix). + +Nix users can use the following command to format with SwiftLint: + +``` +nix develop -c swiftlint lint --fix +``` + +To check for violations without auto-fixing: + +``` +nix develop -c swiftlint lint --strict +``` + +### Updating the Zig Cache Fixed-Output Derivation Hash + +The Nix package depends on a [fixed-output +derivation](https://nix.dev/manual/nix/stable/language/advanced-attributes.html#adv-attr-outputHash) +that manages the Zig package cache. This allows the package to be built in the +Nix sandbox. + +Occasionally (usually when `build.zig.zon` is updated), the hash that +identifies the cache will need to be updated. There are jobs that monitor the +hash in CI, and builds will fail if it drifts. + +To update it, you can run the following in the repository root: + +``` +./nix/build-support/check-zig-cache.sh --update +``` + +This will write out the `nix/zigCacheHash.nix` file with the updated hash +that can then be committed and pushed to fix the builds. + +## Including and Updating Translations + +See the [Contributor's Guide](po/README_CONTRIBUTORS.md) for more details. + +## Checking for Memory Leaks + +While Zig does an amazing job of finding and preventing memory leaks, +Ghostty uses many third-party libraries that are written in C. Improper usage +of those libraries or bugs in those libraries can cause memory leaks that +Zig cannot detect by itself. + +### On Linux + +On Linux the recommended tool to check for memory leaks is Valgrind. The +recommended way to run Valgrind is via `zig build`: + +```sh +zig build run-valgrind +``` + +This builds a Ghostty executable with Valgrind support and runs Valgrind +with the proper flags to ensure we're suppressing known false positives. + +You can combine the same build args with `run-valgrind` that you can with +`run`, such as specifying additional configurations after a trailing `--`. + +## Input Stack Testing + +The input stack is the part of the codebase that starts with a +key event and ends with text encoding being sent to the pty (it +does not include _rendering_ the text, which is part of the +font or rendering stack). + +If you modify any part of the input stack, you must manually verify +all the following input cases work properly. We unfortunately do +not automate this in any way, but if we can do that one day that'd +save a LOT of grief and time. + +Note: this list may not be exhaustive, I'm still working on it. + +### Linux IME + +IME (Input Method Editors) are a common source of bugs in the input stack, +especially on Linux since there are multiple different IME systems +interacting with different windowing systems and application frameworks +all written by different organizations. + +The following matrix should be tested to ensure that all IME input works +properly: + +1. Wayland, X11 +2. ibus, fcitx, none +3. Dead key input (e.g. Spanish), CJK (e.g. Japanese), Emoji, Unicode Hex +4. ibus versions: 1.5.29, 1.5.30, 1.5.31 (each exhibit slightly different behaviors) + +> [!NOTE] +> +> This is a **work in progress**. I'm still working on this list and it +> is not complete. As I find more test cases, I will add them here. + +#### Dead Key Input + +Set your keyboard layout to "Spanish" (or another layout that uses dead keys). + +1. Launch Ghostty +2. Press `'` +3. Press `a` +4. Verify that `á` is displayed + +Note that the dead key may or may not show a preedit state visually. +For ibus and fcitx it does but for the "none" case it does not. Importantly, +the text should be correct when it is sent to the pty. + +We should also test canceling dead key input: + +1. Launch Ghostty +2. Press `'` +3. Press escape +4. Press `a` +5. Verify that `a` is displayed (no diacritic) + +#### CJK Input + +Configure fcitx or ibus with a keyboard layout like Japanese or Mozc. The +exact layout doesn't matter. + +1. Launch Ghostty +2. Press `Ctrl+Shift` to switch to "Hiragana" +3. On a US physical layout, type: `konn`, you should see `こん` in preedit. +4. Press `Enter` +5. Verify that `こん` is displayed in the terminal. + +We should also test switching input methods while preedit is active, which +should commit the text: + +1. Launch Ghostty +2. Press `Ctrl+Shift` to switch to "Hiragana" +3. On a US physical layout, type: `konn`, you should see `こん` in preedit. +4. Press `Ctrl+Shift` to switch to another layout (any) +5. Verify that `こん` is displayed in the terminal as committed text. + +## Nix Virtual Machines + +Several Nix virtual machine definitions are provided by the project for testing +and developing Ghostty against multiple different Linux desktop environments. + +Running these requires a working Nix installation, either Nix on your +favorite Linux distribution, NixOS, or macOS with nix-darwin installed. Further +requirements for macOS are detailed below. + +VMs should only be run on your local desktop and then powered off when not in +use, which will discard any changes to the VM. + +The VM definitions provide minimal software "out of the box" but additional +software can be installed by using standard Nix mechanisms like `nix run nixpkgs#`. + +### Linux + +1. Check out the Ghostty source and change to the directory. +2. Run `nix run .#`. `` can be any of the VMs defined in the + `nix/vm` directory (without the `.nix` suffix) excluding any file prefixed + with `common` or `create`. +3. The VM will build and then launch. Depending on the speed of your system, this + can take a while, but eventually you should get a new VM window. +4. The Ghostty source directory should be mounted to `/tmp/shared` in the VM. Depending + on what UID and GID of the user that you launched the VM as, `/tmp/shared` _may_ be + writable by the VM user, so be careful! + +### macOS + +1. To run the VMs on macOS you will need to enable the Linux builder in your `nix-darwin` + config. This _should_ be as simple as adding `nix.linux-builder.enable=true` to your + configuration and then rebuilding. See [this](https://nixcademy.com/posts/macos-linux-builder/) + blog post for more information about the Linux builder and how to tune the performance. +2. Once the Linux builder has been enabled, you should be able to follow the Linux instructions + above to launch a VM. + +### Custom VMs + +To easily create a custom VM without modifying the Ghostty source, create a new +directory, then create a file called `flake.nix` with the following text in the +new directory. + +``` +{ + inputs = { + nixpkgs.url = "nixpkgs/nixpkgs-unstable"; + ghostty.url = "github:ghostty-org/ghostty"; + }; + outputs = { + nixpkgs, + ghostty, + ... + }: { + nixosConfigurations.custom-vm = ghostty.create-gnome-vm { + nixpkgs = nixpkgs; + system = "x86_64-linux"; + overlay = ghostty.overlays.releasefast; + # module = ./configuration.nix # also works + module = {pkgs, ...}: { + environment.systemPackages = [ + pkgs.btop + ]; + }; + }; + }; +} +``` + +The custom VM can then be run with a command like this: + +``` +nix run .#nixosConfigurations.custom-vm.config.system.build.vm +``` + +A file named `ghostty.qcow2` will be created that is used to persist any changes +made in the VM. To "reset" the VM to default delete the file and it will be +recreated the next time you run the VM. + +### Contributing new VM definitions + +#### VM Acceptance Criteria + +We welcome the contribution of new VM definitions, as long as they meet the following criteria: + +1. They should be different enough from existing VM definitions that they represent a distinct + user (and developer) experience. +2. There's a significant Ghostty user population that uses a similar environment. +3. The VMs can be built using only packages from the current stable NixOS release. + +#### VM Definition Criteria + +1. VMs should be as minimal as possible so that they build and launch quickly. + Additional software can be added at runtime with a command like `nix run nixpkgs#`. +2. VMs should not expose any services to the network, or run any remote access + software like SSH daemons, VNC or RDP. +3. VMs should auto-login using the "ghostty" user. + +## Nix VM Integration Tests + +Several Nix VM tests are provided by the project for testing Ghostty in a "live" +environment rather than just unit tests. + +Running these requires a working Nix installation, either Nix on your +favorite Linux distribution, NixOS, or macOS with nix-darwin installed. Further +requirements for macOS are detailed below. + +### Linux + +1. Check out the Ghostty source and change to the directory. +2. Run `nix run .#checks...driver`. `` should be + `x86_64-linux` or `aarch64-linux` (even on macOS, this launches a Linux + VM, not a macOS one). `` should be one of the tests defined in + `nix/tests.nix`. The test will build and then launch. Depending on the speed + of your system, this can take a while. Eventually though the test should + complete. Hopefully successfully, but if not error messages should be printed + out that can be used to diagnose the issue. +3. To run _all_ of the tests, run `nix flake check`. + +### macOS + +1. To run the VMs on macOS you will need to enable the Linux builder in your `nix-darwin` + config. This _should_ be as simple as adding `nix.linux-builder.enable=true` to your + configuration and then rebuilding. See [this](https://nixcademy.com/posts/macos-linux-builder/) + blog post for more information about the Linux builder and how to tune the performance. +2. Once the Linux builder has been enabled, you should be able to follow the Linux instructions + above to launch a test. + +### Interactively Running Test VMs + +To run a test interactively, run `nix run +.#check...driverInteractive`. This will load a Python console +that can be used to manage the test VMs. In this console run `start_all()` to +start the VM(s). The VMs should boot up and a window should appear showing the +VM's console. + +For more information about the Nix test console, see [the NixOS manual](https://nixos.org/manual/nixos/stable/index.html#sec-call-nixos-test-outside-nixos) + +### SSH Access to Test VMs + +Some test VMs are configured to allow outside SSH access for debugging.

This is not the recommended way to build Ghostty for your +own system. For that, see the primary README. + +1. First, we fetch our dependencies from the internet into a cached directory. + This is the only step that requires internet access: + +```sh +ZIG_GLOBAL_CACHE_DIR=/tmp/offline-cache ./nix/build-support/fetch-zig-cache.sh +``` + +2. Next, we build Ghostty. This step requires no internet access: + +```sh +DESTDIR=/tmp/ghostty \ +zig build \ + --prefix /usr \ + --system /tmp/offline-cache/p \ + -Doptimize=ReleaseFast \ + -Dcpu=baseline +``` + +The build options are covered in the next section, but this will build +and install Ghostty to `/tmp/ghostty` with the prefix `/usr` (i.e. the +binary will be at `/tmp/ghostty/usr/bin/ghostty`). This style is common +for system packages which separate a build and install step, since the +install step can then be done with a `mv` or `cp` command (from `/tmp/ghostty` +to wherever the package manager expects it). + +### Build Options + +Ghostty uses the Zig build system. You can see all available build options by +running `zig build --help`. The following are options that are particularly +relevant to package maintainers: + +- `--prefix`: The installation prefix. Combine with the `DESTDIR` environment + variable to install to a temporary directory for packaging. + +- `--system`: The path to the offline cache directory. This disables + any package fetching from the internet. This flag also triggers all + dependencies to be dynamically linked by default. This flag also makes + the binary a PIE (Position Independent Executable) by default (override + with `-Dpie`). + +- `-Doptimize=ReleaseFast`: Build with optimizations enabled and safety checks + disabled. This is the recommended build mode for distribution. I'd prefer + a safe build but terminal emulators are performance-sensitive and the + safe build is currently too slow. I plan to improve this in the future. + Other build modes are available: `Debug`, `ReleaseSafe`, and `ReleaseSmall`. + +- `-Dcpu=baseline`: Build for the "baseline" CPU of the target architecture. + This avoids building for newer CPU features that may not be available on + all target machines. + +- `-Dtarget=$arch-$os-$abi`: Build for a specific target triple. This is + often necessary for system packages to specify a specific minimum Linux + version, glibc, etc. Run `zig targets` to a get a full list of available + targets. diff --git a/vendor/libghostty-vt/README.md b/vendor/libghostty-vt/README.md new file mode 100644 index 00000000..293f5a6e --- /dev/null +++ b/vendor/libghostty-vt/README.md @@ -0,0 +1,226 @@ + +

+

+ +## About + +Ghostty is a terminal emulator that differentiates itself by being +fast, feature-rich, and native. While there are many excellent terminal +emulators available, they all force you to choose between speed, +features, or native UIs. Ghostty provides all three. + +**`libghostty`** is a cross-platform, zero-dependency C and Zig library +for building terminal emulators or utilizing terminal functionality +(such as style parsing). Anyone can use `libghostty` to build a terminal +emulator or embed a terminal into their own applications. See +[Ghostling](https://github.com/ghostty-org/ghostling) for a minimal complete project +example or the [`examples` directory](https://github.com/ghostty-org/ghostty/tree/main/example) +for smaller examples of using `libghostty` in C and Zig. + +For more details, see [About Ghostty](https://ghostty.org/docs/about). + +## Download + +See the [download page](https://ghostty.org/download) on the Ghostty website. + +## Documentation + +See the [documentation](https://ghostty.org/docs) on the Ghostty website. + +## Contributing and Developing + +If you have any ideas, issues, etc. regarding Ghostty, or would like to +contribute to Ghostty through pull requests, please check out our +["Contributing to Ghostty"](CONTRIBUTING.md) document. Those who would like +to get involved with Ghostty's development as well should also read the +["Developing Ghostty"](HACKING.md) document for more technical details. + +## Roadmap and Status + +Ghostty is stable and in use by millions of people and machines daily. + +The high-level ambitious plan for the project, in order: + +| # | Step | Status | +| :-: | ------------------------------------------------------- | :----: | +| 1 | Standards-compliant terminal emulation | ✅ | +| 2 | Competitive performance | ✅ | +| 3 | Rich windowing features -- multi-window, tabbing, panes | ✅ | +| 4 | Native Platform Experiences | ✅ | +| 5 | Cross-platform `libghostty` for Embeddable Terminals | ✅ | +| 6 | Ghostty-only Terminal Control Sequences | ❌ | + +Additional details for each step in the big roadmap below: + +#### Standards-Compliant Terminal Emulation + +Ghostty implements all of the regularly used control sequences and +can run every mainstream terminal program without issue. For legacy sequences, +we've done a [comprehensive xterm audit](https://github.com/ghostty-org/ghostty/issues/632) +comparing Ghostty's behavior to xterm and building a set of conformance +test cases. + +In addition to legacy sequences (what you'd call real "terminal" emulation), +Ghostty also supports more modern sequences than almost any other terminal +emulator. These features include things like the Kitty graphics protocol, +Kitty image protocol, clipboard sequences, synchronized rendering, +light/dark mode notifications, and many, many more. + +We believe Ghostty is one of the most compliant and feature-rich terminal +emulators available. + +Terminal behavior is partially a de jure standard +(i.e. [ECMA-48](https://ecma-international.org/publications-and-standards/standards/ecma-48/)) +but mostly a de facto standard as defined by popular terminal emulators +worldwide. Ghostty takes the approach that our behavior is defined by +(1) standards, if available, (2) xterm, if the feature exists, (3) +other popular terminals, in that order. This defines what the Ghostty project +views as a "standard." + +#### Competitive Performance + +Ghostty is generally in the same performance category as the other highest +performing terminal emulators. + +"The same performance category" means that Ghostty is much faster than +traditional or "slow" terminals and is within an unnoticeable margin of the +well-known "fast" terminals. For example, Ghostty and Alacritty are usually within +a few percentage points of each other on various benchmarks, but are both +something like 100x faster than Terminal.app and iTerm. However, Ghostty +is much more feature rich than Alacritty and has a much more native app +experience. + +This performance is achieved through high-level architectural decisions and +low-level optimizations. At a high-level, Ghostty has a multi-threaded +architecture with a dedicated read thread, write thread, and render thread +per terminal. Our renderer uses OpenGL on Linux and Metal on macOS. +Our read thread has a heavily optimized terminal parser that leverages +CPU-specific SIMD instructions. Etc. + +#### Rich Windowing Features + +The Mac and Linux (build with GTK) apps support multi-window, tabbing, and +splits with additional features such as tab renaming, coloring, etc. These +features allow for a higher degree of organization and customization than +single-window terminals. + +#### Native Platform Experiences + +Ghostty is a cross-platform terminal emulator but we don't aim for a +least-common-denominator experience. There is a large, shared core written +in Zig but we do a lot of platform-native things: + +- The macOS app is a true SwiftUI-based application with all the things you + would expect such as real windowing, menu bars, a settings GUI, etc. +- macOS uses a true Metal renderer with CoreText for font discovery. +- macOS supports AppleScript, Apple Shortcuts (AppIntents), etc. +- The Linux app is built with GTK. +- The Linux app integrates deeply with systemd if available for things + like always-on, new windows in a single instance, cgroup isolation, etc. + +Our goal with Ghostty is for users of whatever platform they run Ghostty +on to think that Ghostty was built for their platform first and maybe even +exclusively. We want Ghostty to feel like a native app on every platform, +for the best definition of "native" on each platform. + +#### Cross-platform `libghostty` for Embeddable Terminals + +In addition to being a standalone terminal emulator, Ghostty is a +C-compatible library for embedding a fast, feature-rich terminal emulator +in any 3rd party project. This library is called `libghostty`. + +Due to the scope of this project, we're breaking libghostty down into +separate actually libraries, starting with `libghostty-vt`. The goal of +this project is to focus on parsing terminal sequences and maintaining +terminal state. This is covered in more detail in this +[blog post](https://mitchellh.com/writing/libghostty-is-coming). + +`libghostty-vt` is already available and usable today for Zig and C and +is compatible for macOS, Linux, Windows, and WebAssembly. The functionality +is extremely stable (since its been proven in Ghostty GUI for a long time), +but the API signatures are still in flux. + +`libghostty` is already heavily in use. See [`examples`](https://github.com/ghostty-org/ghostty/tree/main/example) +for small examples of using `libghostty` in C and Zig or the +[Ghostling](https://github.com/ghostty-org/ghostling) project for a +complete example. See [awesome-libghostty](https://github.com/Uzaaft/awesome-libghostty) +for a list of projects and resources related to `libghostty`. + +We haven't tagged libghostty with a version yet and we're still working +on a better docs experience, but our [Doxygen website](https://libghostty.tip.ghostty.org/) +is a good resource for the C API. + +#### Ghostty-only Terminal Control Sequences + +We want and believe that terminal applications can and should be able +to do so much more. We've worked hard to support a wide variety of modern +sequences created by other terminal emulators towards this end, but we also +want to fill the gaps by creating our own sequences. + +We've been hesitant to do this up until now because we don't want to create +more fragmentation in the terminal ecosystem by creating sequences that only +work in Ghostty. But, we do want to balance that with the desire to push the +terminal forward with stagnant standards and the slow pace of change in the +terminal ecosystem. + +We haven't done any of this yet. + +## Crash Reports + +Ghostty has a built-in crash reporter that will generate and save crash +reports to disk. The crash reports are saved to the `$XDG_STATE_HOME/ghostty/crash` +directory. If `$XDG_STATE_HOME` is not set, the default is `~/.local/state`. +**Crash reports are _not_ automatically sent anywhere off your machine.** + +Crash reports are only generated the next time Ghostty is started after a +crash. If Ghostty crashes and you want to generate a crash report, you must +restart Ghostty at least once. You should see a message in the log that a +crash report was generated. + +> [!NOTE] +> +> Use the `ghostty +crash-report` CLI command to get a list of available crash +> reports. A future version of Ghostty will make the contents of the crash +> reports more easily viewable through the CLI and GUI. + +Crash reports end in the `.ghosttycrash` extension. The crash reports are in +[Sentry envelope format](https://develop.sentry.dev/sdk/envelopes/). You can +upload these to your own Sentry account to view their contents, but the format +is also publicly documented so any other available tools can also be used. +The `ghostty +crash-report` CLI command can be used to list any crash reports. +A future version of Ghostty will show you the contents of the crash report +directly in the terminal. + +To send the crash report to the Ghostty project, you can use the following +CLI command using the [Sentry CLI](https://docs.sentry.io/cli/installation/): + +```shell-session +SENTRY_DSN=https://e914ee84fd895c4fe324afa3e53dac76@o4507352570920960.ingest.us.sentry.io/4507850923638784 sentry-cli send-envelope --raw +``` + +> [!WARNING] +> +> The crash report can contain sensitive information. The report doesn't +> purposely contain sensitive information, but it does contain the full +> stack memory of each thread at the time of the crash. This information +> is used to rebuild the stack trace but can also contain sensitive data +> depending on when the crash occurred. diff --git a/vendor/libghostty-vt/VERSION b/vendor/libghostty-vt/VERSION new file mode 100644 index 00000000..c2828575 --- /dev/null +++ b/vendor/libghostty-vt/VERSION @@ -0,0 +1 @@ +1.3.2-main+0a492fd \ No newline at end of file diff --git a/vendor/libghostty-vt/build.zig b/vendor/libghostty-vt/build.zig new file mode 100644 index 00000000..45ad3ba1 --- /dev/null +++ b/vendor/libghostty-vt/build.zig @@ -0,0 +1,371 @@ +const std = @import("std"); +const assert = std.debug.assert; +const builtin = @import("builtin"); +const buildpkg = @import("src/build/main.zig"); + +/// App version from build.zig.zon. +const app_zon_version = @import("build.zig.zon").version; + +/// Libghostty version.

Note that this will +output the full default configuration with docs to stdout, so you may want to +pipe that through a pager, an editor, etc. + +Note: You'll see a lot of weird blank configurations like `font-family =`. This +is a valid syntax to specify the default behavior (no value). The `+show-config` +outputs it so it's clear that key is defaulting and also to have something to +attach the doc comment to. + +You can also see and read all available configuration options in the source +Config structure. The available keys are the keys verbatim, and their possible +values are typically documented in the comments. You also can search for +the public config files of many Ghostty users for examples and inspiration. + +## Configuration Errors + +If your configuration file has any errors, Ghostty does its best to ignore +them and move on. Configuration errors will be logged. + +## Debugging Configuration + +You can verify that configuration is being properly loaded by looking at the +debug output of Ghostty. + +In the debug output, you should see in the first 20 lines or so messages about +loading (or not loading) a configuration file, as well as any errors it may have +encountered. Configuration errors are also shown in a dedicated window on both +macOS and Linux (GTK). Ghostty does not treat configuration errors as fatal and +will fall back to default values for erroneous keys. + +You can also view the full configuration Ghostty is loading using `ghostty ++show-config` from the command-line. Use the `--help` flag to additional options +for that command. + +## Logging + +Ghostty can write logs to a number of destinations. On all platforms, logging to +`stderr` is available. Depending on the platform and how Ghostty was launched, +logs sent to `stderr` may be stored by the system and made available for later +retrieval. + +On Linux if Ghostty is launched by the default `systemd` user service, you can use +`journald` to see Ghostty's logs: `journalctl --user --unit app-com.mitchellh.ghostty.service`. + +On macOS logging to the macOS unified log is available and enabled by default. +--Use the system `log` CLI to view Ghostty's logs: `sudo log stream --level debug +--predicate 'subsystem=="com.mitchellh.ghostty"'`. + +Ghostty's logging can be configured in two ways. The first is by what +optimization level Ghostty is compiled with. If Ghostty is compiled with `Debug` +optimizations debug logs will be output to `stderr`. If Ghostty is compiled with +any other optimization the debug logs will not be output to `stderr`. + +Ghostty also checks the `GHOSTTY_LOG` environment variable. It can be used +to control which destinations receive logs. Ghostty currently defines two +destinations: + +- `stderr` - logging to `stderr`. +- `macos` - logging to macOS's unified log (has no effect on non-macOS platforms). + +Combine values with a comma to enable multiple destinations. Prefix a +destination with `no-` to disable it. Enabling and disabling destinations +can be done at the same time. Setting `GHOSTTY_LOG` to `true` will enable all +destinations.
