* Add alacritty_terminal option to escape pty argsfeeiyu2025-08-02
| | | | | | | | | | | This adds a new `escape_args` option to `tty::Options` on Windows, which can be used to automatically escape all arguments passed to the shell. While useful to automatically make most arguments work on Windows, there are some scenarios where it is not possible for users to properly specify arguments with this option enabled (e.g.: `cmd /c`). An option should always be present to disable this option when used. The implementation is based on the `Command` code in Rust's STD lib.
* Migrate to 2024 editionChristian Duerr2025-07-13

* Remove cstr! macro in favor of literal notationKirill Chibisov2025-07-01
| | | | | Also apply clippy changes while at it. Closes #8002.
* Apply clamp for opacityKirill Chibisov2025-05-31
| | | | Previously opacity was not clamping during reading it from the config or via IPC.
* Add IPC config retrieval subcommandChristian Duerr2025-05-29
| | | | | | | | | | | | | | | This patch adds a new `alacritty msg get-config` subcommand which can retrieve the current config from any Alacritty window using the IPC socket. The command will always print the full configuration file in JSON, without the ability to filter which values are returned, leaning on tools like `jq` instead of adding this complexity to Alacritty. Contrary to deserialization, this relies heavily on the default serialization implementations to reduce the necessary changes. Key and Mouse bindings are omitted entirely since their structure is very complex and they tend to just bloat the message size without having an obvious usecase.
* Fix hint binding IPC overridesChristian Duerr2025-05-21
| | | | | | | | | | | | | | | | | This fixes an issue where changes made to the bindings of a hint through IPC were completely ignored, since the hint key bindings were only generated on config load without regeneration on IPC config override. While it would be possible to just filter out remove hint key bindings based on their action and then repopulate them on IPC config reload, this solution would be quite hacky. To have a better distinction between traditional and hint key bindings, the two have been entirely separated and hint bindings are just converted to key bindings on demand. This allows easily replacing the entire hint array without any post-processing, making it simpler to maintain for future changes. Closes #8568.
* Add backslash to invalid characters for URL regexKaylem Brown-Malone2025-01-29
| | | | This adds the `\` character to the list of characters which will terminate matches in Alacritty's default hint for URL recognition.
* Add option to drain PTY on shutdownAndrew Borg (Kashin)2025-01-16
| | | | | This patch removes the `hold` option on `alacritty_terminal` in favor of a `drain_on_exit` option, which will drain the PTY before shutdown. The hold logic is instead handled in `alacritty`.
* Fix racing condition in hint triggeringChristian Duerr2024-11-02
| | | | | | | | | | | This fixes an issue with hints where it was possible that the terminal content of highlighted hints changed between the highlighted hint update and the activation of the hint. This patch always validates the hint's text content against the hint itself to ensure that the content is still valid for the original hint which triggered the highlight. Closes #8277.
* Change ctrl+shift+u to ctrl+shift+oKirill Chibisov2024-10-10
| | | | | Avoid collisions with IMEs by using ctrl+shift+o. ctrl+shift+u is bound to open unicode input in a lot of IMEs by default meaning that users won't ever see the url hints UI.
* Move root config fields to `[general]` sectionChristian Duerr2024-10-02
| | | | | | | | | | | Some users struggle with TOML, since root options must always be at the top of the file, since they're otherwise associated with the last table. To avoid misunderstandings, all root-level fields have been removed. A new `general` section was added to allow housing configuration options that do not fit into any more specific groups. Closes #7906.
* Fix spelling errorsJosh Soref2024-05-24

* Allow setting terminal env vars via PTY optionsKirill Bulatov2024-03-18
| | | Closes #7778.
* Fix hint `Select` action for hyperlink escapeChristian Duerr2024-03-12
| | | | | | | | | | | | This fixes an issue where the `Select` action for hyperlink escape text would select the entire line, instead of selecting only the hyperlink itself. It also changes the way hyperlinks with the same ID are highlighted, removing the restriction of being on consecutive lines and instead highlighting all visible cells that correspond to the matching hyperlink. Closes #7766.
* Fix replacing optional fieldsChristian Duerr2024-01-02
| | | | | | | This fixes an issue with the default `SerdeReplace` implementation where it would never recurse through options but always replace the entire option with the new value. Closes #7518.
* Implement kitty's keyboard protocolKirill Chibisov2023-12-06
| | | | | | | | The protocol enables robust key reporting for the applications, so they could bind more keys and the user won't have collisions with the normal control keys. Links: https://sw.kovidgoyal.net/kitty/keyboard-protocol Fixes #6378.
* Remove `alacritty_config` from alacritty_terminalKirill Chibisov2023-11-10
| | | | | There's no need to force alacritty's user configuration on other users of the crate, thus provide the options actually used by alacritty_terminal itself.
* Fix regex memory usageChristian Duerr2023-09-17
| | | | | | | | | | | | | | | | | | This fixes an issue where regexes with a large number of possible states would consume excessive memory, since the entire DFA was compiled ahead of time. To solve this, the DFA is now built at runtime using `regex-automata`'s hybrid DFA. There are however still some checks performed ahead of time, causing errors with obscenely large regexes (`[0-9A-Za-z]{999999999}`), which shouldn't cause any issues. A regex which is large, but not large enough to fail the NFA construction (like `[0-9A-Za-z]{999999}`) will cause a long search of the entire grid, but will complete and show the match. Closes #7097.
* Update regex-automata to v0.3.6Christian Duerr2023-08-27
| | | This seems like a sensible first step before looking into #7097.
* Make URL_REGEX more strictKirill Bulatov2023-07-22

* Update to the new winit keyboard APIKirill Chibisov2023-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main highlight of this update is that alacritty will now use new keyboard API from the winit, which resolves a lot of issues around key bindings, such as ability to bind dead keys. It also fixes long standing issues with the virtual key code bindings and make bindings in general more predictable. It also makes our default Vi key bindings fully working. Given that alacritty was using `VirtualKey` directly in the bindings from the winit, and winit simply removed the enum, we've added internal conversions to minimize the fallout, but new way to specify the bindings should be more intuitive. Other part of this update fixes some forward compatibility bugs with the Wayland backend, given that wayland-rs 0.30 is fully forward compatible. The update also fixes weird Maximized startup issues on GNOME Wayland, however they were present on any sane compositor. Fixes #6842. Fixes #6455. Fixes #6184. Fixes #5684. Fixes #3574. Fixes #3460. Fixes #1336. Fixes #892. Fixes #458. Fixes #55.
* Fix legacy bindings taking precedence over new onesKirill Chibisov2023-07-03
| | | | | | | | | | They were compared by len, but it's was wrong from the start, since a user provided binding could remove more than one builtin binding, so it was impossible for users to use their own bindings. The most reliable way to do so is to use `Option`, given that we fill default during deserialization. Fixes #7050.
* Add errors for deserializing with unknown fieldsChristian Duerr2023-06-17
| | | | | | | | | Currently there are still some places where `Deserialize` is used rather than `ConfigDeserialize`, which means that the built-in warning for unused fields is not emitted automatically. To ensure users don't have invalid configurations, the `#[serde(deny_unknown_fields)]` annotation has been added to these structs, making it a hard error when an unknown field is present.
* Add option to persist hints after selectionSonu Bardai2023-06-15
| | | Closes #6976.
* Fix warnings for config importsChristian Duerr2023-06-14
| | | Closes #6996.
* Switch to TOML configuration formatChristian Duerr2023-06-12
| | | | | | | | | | | | | | | This switches Alacritty's default configuration format from yaml to toml. While yaml is still supported, it is done by converting it to toml and should be removed entirely in the future. All existing features were persisted based on my testing. Behavior should not change much, though `--option` might have slightly different behavior since the entire line is not interpreted as one line of toml. A new `alacritty migrate` subcommand has been added which allows automatic migration from yaml to toml. This also could be used as a facility to automatically fix configuration file changes in the future. Closes #6592.
* Update winit to 0.28Kirill Chibisov2023-02-02
| | | | | | | | Fixes #6644. Fixes #6615. Fixes #6558. Fixes #6515. Fixes #3187. Fixes #62.
* Update glutin to 0.30.0Kirill Chibisov2022-11-03
| | | | | | | | | | | | | | | The glutin 0.30.0 update decouples glutin from winit which provides us with basis for a multithreaded renderer. This also improves robustness of our configuration picking, context creation, and surface handling. As an example we're now able to start on systems without a vsync, we don't try to build lots of contexts to check if some config works, and so on. That also brings us possibility to handle context losses, but that's a future work. Fixes #1268.
* Add IPC config subcommandChristian Duerr2022-09-01
| | | | | | | | | | | | | | | | | | | | This patch adds a new mechanism for changing configuration options without editing the configuration file, by sending options to running instances through `alacritty msg`. Each window will load Alacritty's configuration file by default and then accept IPC messages for config updates using the `alacritty msg config` subcommand. By default all windows will be updated, individual windows can be addressed using `alacritty msg config --window-id "$ALACRITTY_WINDOW_ID"`. Each option will replace the config's current value and cannot be reset until Alacritty is restarted or the option is overwritten with a new value. Configuration options are passed in the format `field.subfield=value`, where `value` is interpreted as yaml. Closes #472.
* Add support for hyperlink escape sequenceKirill Chibisov2022-07-10
| | | | | | | This commit adds support for hyperlink escape sequence `OSC 8 ; params ; URI ST`. The configuration option responsible for those is `hints.enabled.hyperlinks`. Fixes #922.
* Fix a few minor clippy lintsYuri Astrakhan2022-06-02

* Add parameters to `msg create-window` subcommandKirill Chibisov2021-11-22
| | | | | | | | | | | | | | | Alacritty's `msg create-window` subcommand would previously inherit all the CLI parameters from the original executable. However not only could this lead to unexpected behavior, it also prevents multi-window users from making use of parameters like `-e`, `--working-directory`, or `--hold`. This is solved by adding a JSON-based message format to the IPC socket messages which instructs the Alacritty server on which CLI parameters should be used to create the new window. Fixes #5562. Fixes #5561. Fixes #5560.
* Add multi-window supportChristian Duerr2021-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously Alacritty would always initialize only a single terminal emulator window feeding into the winit event loop, however some platforms like macOS expect all windows to be spawned by the same process and this "daemon-mode" can also come with the advantage of increased memory efficiency. The event loop has been restructured to handle all window-specific events only by the event processing context with the associated window id. This makes it possible to add new terminal windows at any time using the WindowContext::new function call. Some preliminary tests have shown that for empty terminals, this reduces the cost of additional terminal emulators from ~100M to ~6M. However at this point the robustness of the daemon against issues with individual terminals has not been refined, making the reliability of this system questionable. New windows can be created either by using the new `CreateNewWindow` action, or with the `alacritty msg create-window` subcommand. The subcommand sends a message to an IPC socket which Alacritty listens on, its location can be found in the `ALACRITTY_SOCKET` environment variable. Fixes #607.
* Fix 'background_opacity' deprecationChristian Duerr2021-08-23
| | | | | | | | | | During the deprecation of the 'background_opacity' field, it was incorrectly renamed to 'window_opacity'. This changes that back to ensure the old field still works and a warning is emitted accordingly. See the original regression here: https://github.com/alacritty/alacritty/commit/c24d7dfd0d2d8849f0398d7cb1a65d6562ee7a0d#diff-f92f0b1ad70a7b75b7266f3c9e569025e023d186814aa88c2b690800850ccb78L72-R73 Fixes #5437.
* Add option to apply opacity to all background colorsKirill Chibisov2021-08-16
| | | | | | | In some cases it could be desired to apply 'background_opacity' to all background colors instead of just 'colors.primary.background', thus adding an 'colors.opaque_background_colors' option to control that. Fixes #741.
* Fix clippy warningsChristian Duerr2021-07-03

* Add modes to regex hint bindingsJoshua Ortiz2021-06-19
| | | Fixes #5154.
* Add ipfs/ipns URL scheme supportAlfonso Montero2021-05-21
|
* Fix default URL bindingChristian Duerr2021-05-10
| | | | | The default binding for launching the URL hints was documented as Ctrl+Shift+U, but never actually set. This adds this binding as the default instead of having URLs only launchable using the mouse.
* Fix URL highlighting with unicode whitespaceChristian Duerr2021-05-09
| | | | | | The URL highlighting regex would automatically terminate on an ascii whitespace, however there are several other forms of whitespace that are indistinguisable to a user from normal whitespace. To make things a little more intuitive, all unicode whitespace will now terminate URLs.
* Add support for magnet URLsRaphael Nestler2021-04-30

* Add hint action for moving the vi cursorChristian Duerr2021-04-15
| | | Fixes #4319.
* Add vi/mouse hint highlighting supportChristian Duerr2021-04-13
| | | | | This patch removes the old url highlighting code and replaces it with a new implementation making use of hints as sources for finding matches in the terminal.
* Add copy/paste/select hint actionsChristian Duerr2021-04-03
| | | | | | This adds some built-in actions for handling hint selections without having to spawn external applications. The new actions are `Copy`, `Select` and `Paste`.
* Add regex terminal hintsChristian Duerr2021-03-01
| | | | | | | | | | | | | | | | This adds support for hints, which allow opening parts of the visual buffer with external programs if they match a certain regex. This is done using a visual overlay triggered on a specified key binding, which then instructs the user which keys they need to press to pass the text to the application. In the future it should be possible to supply some built-in actions for Copy/Pasting the action and using this to launch text when clicking on it with the mouse. But the current implementation should already be useful as-is. Fixes #2792. Fixes #2536.
* Update dependenciesChristian Duerr2021-02-13
| | | | | | This introduces some duplicate dependencies, though they are necessary to build properly without any warnings. Fixes #4735.
* Move renderable cell transformation to alacrittyChristian Duerr2021-01-24
| | | | | | | | | | | | This refactors a large chunk of the alacritty_terminal API to expose all data necessary for rendering uniformly through the `renderable_content` call. This also no longer transforms the cells for rendering by a GUI but instead just reports the content from a terminal emulation perspective. The transformation into renderable cells is now done inside the alacritty crate. Since the terminal itself only ever needs to know about modified color RGB values, the configuration for colors was moved to the alacritty UI code.
* Replace serde's derive with custom proc macroChristian Duerr2020-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces the existing `Deserialize` derive from serde with a `ConfigDeserialize` derive. The goal of this new proc macro is to allow a more error-friendly deserialization for the Alacritty configuration file without having to manage a lot of boilerplate code inside the configuration modules. The first part of the derive macro is for struct deserialization. This takes structs which have `Default` implemented and will only replace fields which can be successfully deserialized. Otherwise the `log` crate is used for printing errors. Since this deserialization takes the default value from the struct instead of the value, it removes the necessity for creating new types just to implement `Default` on them for deserialization. Additionally, the struct deserialization also checks for `Option` values and makes sure that explicitly specifying `none` as text literal is allowed for all options. The other part of the derive macro is responsible for deserializing enums. While only enums with Unit variants are supported, it will automatically implement a deserializer for these enums which accepts any form of capitalization. Since this custom derive prevents us from using serde's attributes on fields, some of the attributes have been reimplemented for `ConfigDeserialize`. These include `#[config(flatten)]`, `#[config(skip)]` and `#[config(alias = "alias)]`. The flatten attribute is currently limited to at most one per struct. Additionally the `#[config(deprecated = "optional message")]` attribute allows easily defining uniform deprecation messages for fields on structs.
* Remove redundant CLI flagsChristian Duerr2020-11-26
| | | | | | | | | | | | | This removes some of Alacritty's CLI flags since the same functionality is provided by the '--option' flag now. The removed flags are: * '--persistent-logging' * '--live-config-reload' * '--no-live-config-reload' * '--dimensions' * '--position' Fixes #4246.
* Add configuration file importsChristian Duerr2020-08-21
| | | | | | | | | | | | | | | | | | | This adds the ability for users to have multiple configuration files which all inherit from each other. The order of imports is chronological, branching out to the deepest children first and overriding every field with that of the configuration files that are loaded at a later point in time. Live config reload watches the directories of all configuration files, allowing edits in any of them to update Alacritty immediately. While the imports are live reloaded, a new configuration file watcher will only be spawned once Alacritty is restarted. Since this might cause loops which would be very difficult to detect, a maximum depth is set to limit the recursion possible with nested configuration files. Fixes #779.
