* 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 `alacritty msg config` toml replacementChristian Duerr2023-06-15
| | | | | | | | | | This fixes a regression introduced in bd49067 which broke the override of configuration file variables using `alacritty msg config`. To fix this the `replace` functionality was rewritten to behave more like the `serde_utils::merge` where entire values are inserted into the existing structure rather than separating the keys from the values. Fixes: bd49067 (Switch to TOML configuration format)
* 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.

* Fix `;` character in URI OSC 8 payloadKirill Chibisov2023-03-19
| | | | | The special character `;` can be not URL-encoded, thus it'll add extra parameter in the payload. Handle it joining extra parameters with the `;` as a separator.
* Update winit to 0.28Kirill Chibisov2023-02-02
| | | | | | | | Fixes #6644. Fixes #6615. Fixes #6558. Fixes #6515. Fixes #3187. Fixes #62.
* Fix clippy warningsChris Copeland2022-07-25

* Replace `map().unwrap_or()` with `map_or()`Chris Copeland2022-07-20
| | | Use a `map_or` instead of a `map().unwrap_or()` chain.
* 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 DEC Special Character Set (Line drawing)André Kugland2022-06-01
| | | | | | | | This patch resolves some mapping issues with the line drawing character set where characters like linefeed were incorrectly mapped to their proper character representation rather than the codepoint of their identification glpyh. Co-authored-by: Christian Duerr <contact@christianduerr.com>
* Enable damage tracking only on WaylandKirill Chibisov2022-05-20
| | | | | | | | | | Other platforms don't have such concepts in general or have them via different interfaces not related to EGL. This commit also resolves some minor clippy issues. Fixes #6051. Co-authored-by: Christian Duerr <contact@christianduerr.com>
* Fix OSC 4 color response formatChristian Duerr2022-03-31
| | | | | | | | | | The commit 60ef17e introduced support for the color query response escape for OSC 4, however it did omit the `4;` prefix and started the OSC with just the color index. This patch fixes this bug and correctly responds to queries with full OSC 4 format, including prefix plus color index. Fixes #5981.
* Add colored underline supportKirill Chibisov2022-03-16
| | | | | | | | | This commit adds support for colored underline and refines the dynamic extra storage. The extra storage now is using `Arc` making cloning it way faster compared to `Box` approach which scales really well when it comes to cloning in `Term::write_at_cursor`, since cloning `Arc` is constant time. Fixes #4142.
* Add support for dashed and dotted underlinesKirill Chibisov2022-02-14
| | | | This finishes implementation of underline styles provided by `CSI 4 : [1-5] m` escape sequence.
* Add support for drawing undercurlsKirill Chibisov2022-02-08
| | | Fixes #1628.
* Fix OSC 104 with empty second parameterDaftMouse2022-01-20
| | | | | | This fixes a bug where using OSC 104 without parameters but with a trailling semicolon (e.g. '\e]104;\e\\') would not be handled. Fixes #5542.
* Add ´?´ support to OSC 4DaftMouse2022-01-15

* Fix CreateNewWindow CLI fallbackChristian Duerr2021-12-23
| | | | | | | | | | | | | | The existing behavior for the new CreateNewWindow actions was to always pass in their own options, which would discard the existing options configured on the terminal's PTY config. To fix this the behavior for CreateNewWindow is now the same as for the initial window creation, the config values are overwritten conditionally based on their individual presence in the CLI options. However all temporary CLI options set on the "master" Alacritty instance are discarded by all future windows. Fixes #5659.
* Fix out of order terminal query responsesChristian Duerr2021-04-17
| | | | | | | | | | | | | This forces all responses made to the PTY through the indirection of the UI event loop, making sure that the writes to the PTY are in the same order as the original requests. This just delays all escape sequences by forcing them through the event loop, ideally all responses which are not asynchronous (like a clipboard read) would be made immediately. However since some escapes require feedback from the UI to mutable structures like the config (e.g. color query escapes), this would require additional locking. Fixes #4872.
* Unify the grid line indexing typesChristian Duerr2021-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously Alacritty was using two different ways to reference lines in the terminal. Either a `usize`, or a `Line(usize)`. These indexing systems both served different purposes, but made it difficult to reason about logic involving these systems because of its inconsistency. To resolve this issue, a single new `Line(i32)` type has been introduced. All existing references to lines and points now rely on this definition of a line. The indexing starts at the top of the terminal region with the line 0, which matches the line 1 used by escape sequences. Each line in the history becomes increasingly negative and the bottommost line is equal to the number of visible lines minus one. Having a system which goes into the negatives allows following the escape sequence's indexing system closely, while at the same time making it trivial to implement `Ord` for points. The Alacritty UI crate is the only place which has a different indexing system, since rendering and input puts the zero line at the top of the viewport, rather than the top of the terminal region. All instances which refer to a number of lines/columns instead of just a single Line/Column have also been changed to use a `usize` instead. This way a Line/Column will always refer to a specific place in the grid and no confusion is created by having a count of lines as a possible index into the grid storage.
* Add support for synchronized updatesChristian Duerr2021-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements support for temporarily freezing the terminal grid to prevent rendering of incomplete frames. This can be triggered using the escapes `DCS = 1 s` (start) and `DCS = 2 s` (end). The synchronization is implemented by forwarding all received PTY bytes to a 2 MiB buffer. This should allow updating the entire grid even if it is fairly dense. Unfortunately this also means that another branch is necessary in Alacritty's parser which does have a slight performance impact. In a previous version the freezing was implemented by caching the renderable grid state whenever a synchronized update is started. While this strategy makes it possible to implement this without any performance impact without synchronized updates, a significant performance overhead is introduced whenever a synchronized update is started. Since this can happen thousands of times per frame, it is not a feasible solution. While it would be possible to render at most one synchronized update per frame, it is possible that another synchronized update comes in at any time and stays active for an extended period. As a result the state visible before the long synchronization would be the first received update per frame, not the last, which could lead to the user missing important information during the long freezing interval. Fixes #598.
* Match intermediates directly in CSI parserChristian Duerr2021-02-24
| | | | | | | | There's no point in always trying to access the first field of the intermediates when the only goal is figuring out that there is none. Matching on all intermediates should make it possible to easily match multiple intermediates directly using array matchers.
* 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.
* Use ConfigDeserialize for all config enumsChristian Duerr2020-12-31
| | | | | | | This fixes up all of the remaining enums which are used in the configuration file to make sure they all support fully case insensitive deserialization. Fixes #4611.
* Fix invalid ESC escape sequence parsingChristian Duerr2020-12-17
| | | | | | | | | This strictens the ESC escape sequence parser to prevent invalid intermediates from being ignored. Previously the parser would just look at the first intermediate without validating that the rest of them is empty. If an escape like `\e(#0` is used now, it will no longer be accepted as `\e(0` since the intermediate `#` is also present.
* Fix DoS caused by excessive CSI parameter valuesChristian Duerr2020-11-26
|
* Add blinking cursor supportDettorer2020-11-23
| | | | | | | | This adds support for blinking the terminal cursor. This can be controlled either using the configuration file, or using escape sequences. The supported control sequences for changing the blinking state are `CSI Ps SP q` and private mode 12.
* Error on warnings when running clippyKirill Chibisov2020-10-29
| | | | | It should simplify tracking of new warnings raised on CI builds and when cross checking. This commit also enables warnings for 'rust_2018_idioms' and 'future_incompatible'.
* Add support for urgency hints CSITaylor Blau2020-10-10
| | | | | | | | | | | | | | | | | | | | | | | Teach Alacritty to stop setting the window as urgent upon a bell by emulating xterm's 'bellIsUrgent' resource and relevant CSI. When this resource is enabled (with 'CSI ? 1042 h'), a bell event causes the window to be marked as urgent. When the resource is disabled (with 'CSI ? 1042 l'), the window is not marked urgent in the event of a bell. There are two wrinkles worth noting here: - The 'TermMode::URGENCY_HINTS' does _not_ affect the terminal's configured bell command, since we only want to control whether or not the window is marked as urgent, not anything else. - In xterm, the 'bellIsUrgent' resource is _disabled_ by default. Since bouncing the dock icon has been the default in Alacritty on macOS thus far, do not make an effort to change that in this patch. This allows users to emit "\e[?1042l" and disable bouncing the dock icon. Fixes #2950.
* Add support for single line terminalsii412020-09-27
| | | | | | | | | | | | | | | | | This changes the minimum terminal dimensions from 2 lines and 2 columns, to 1 line and 2 columns. This also reworks the `SizeInfo` to store the number of columns and lines and consistently has only the terminal lines/columns stored, instead of including the message bar and search in some places of the Alacritty renderer/input. These new changes also make it easy to properly start the selection scrolling as soon as the mouse is over the message bar, instead of waiting until it is beyond it. Fixes #4207.

* Add escape to report text area sizeAyose Cazorla2020-08-28
| | | | This implements the escapes `CSI 14 t` and `CSI 18 t` which report the text area size in pixels and characters.
* Add support for double underlinesChristian Duerr2020-08-12
| | | | | | | | | | | | | This adds support for double underlines using the colon separated escape sequence `CSI 4 : 2 m`. Alacritty will now also always fallback to the normal underline in case any of the other underlines like the undercurl are specified. The escape sequence `CSI 4 : 0 m` can now be used to clear all underlines. Some terminals support `CSI 21 m` for double underline, but since Alacritty already uses that as cancel bold which is a little more consistent, that behavior has not changed. So the colon separated variant must be used.
* Add support for colon separated SGR parametersChristian Duerr2020-08-07
| | | | | This implements the colon separated form of SGR 38 and 48. Fixes #1485.
* Add secondary DA supportChristian Duerr2020-07-23
| | | | | | | | | | | This adds support for the secondary DA escape sequence response. Alacritty's version is formatted allowing for up to 99 minor and patch versions, which should be sufficient. The tertiary DA is intentionally not implemented and marked as rejected in the documentation, since a lot of terminals do not support it, or report useless data (XTerm/URxvt/Kitty). Fixes #3100.
* Add regex scrollback buffer searchChristian Duerr2020-07-09
| | | | | | | | | | This adds a new regex search which allows searching the entire scrollback and jumping between matches using the vi mode. All visible matches should be highlighted unless their lines are excessively long. This should help with performance since highlighting is done during render time. Fixes #1017.
* Document supported escape sequencesChristian Duerr2020-07-03
| | | Fixes #3440.
* Remove copypasta dependency from alacritty_terminalKirill Chibisov2020-06-07
|
* Remove copyright notice from filesChristian Duerr2020-06-06
| | | | | | | | | | | | | | Keeping the license as part of every file bloats up the files unnecessarily and introduces an additional overhead to the creation of new modules. Since cargo already provides excellent dependency management, most of the code-reuse of Alacritty should occur through Rust's dependency management instead of copying it source. If code is copied partially, copying the license from the main license file should be just as easy as copying from the top of the file and making some adjustments based on where it is used is likely necessary anyways.
* Refactor Term/Grid separationChristian Duerr2020-05-30
| | | | | | | | | | | This commit aims to clear up the separation between Term and Grid to make way for implementing search. The `cursor` and `cursor_save` have been moved to the grid, since they're always bound to their specific grid and this makes updating easier. Since the selection is independent of the active grid, it has been moved to the `Term`.
* Extend style guideline documentationChristian Duerr2020-05-05

* Fix live config reload for window titleChristian Duerr2020-03-14
| | | | | | | | | | | | | This enables live config reload for the window title. This includes updating the title after it has been pushed and popped from the title stack. The dynamic title option also isn't disabled automatically anymore when the title is set in the config. If the title is set from CLI, the behavior is unchanged and dynamic title changes are still disabled. If the dynamic title is disabled in the config, the title is still updated when the config title is changed. Dynamic title now only prevents changes to the UI's title.
* Remove HollowBlock/Hidden config cursor stylesRémi Garde2020-03-02
| | | Fixes #3367.
* Fix parser stopping at unknown modesChristian Duerr2020-02-15
| | | | | | | This resolves an issue in the parser where it would stop as soon as the first unknown value is encountered in private mode/sgr attribute escapes. Fixes #3339.
* Bump vte and urlocatorChristian Duerr2020-02-11
| | | Fixes #3247.
* Revert "Fix backspace deleting chars when IME is open"Christian Duerr2020-02-10
| | | | | | | | | | | This reverts commit 7f4dce2ee04859fb0b48f15cf808b60065778703. Originally it was assumed that macOS always sends the \x7f on backspace anyways, however this is not true. It seems like the character on backspace can change even within the same terminal session, so we need to have our own binding to reliably set the correct binding. A solution for #1606 should be implemented in cooperation with winit.
* Mirror OSC query terminatorChristian Duerr2020-01-31
| | | Fixes #3091.
* Bump VTE to 0.5.0Christian Duerr2020-01-12
| | | | | | | | | | This change includes dynamic escape buffer support in VTE, which allows us to have arbitrary escape sizes. Since tmux could potentially use very long escapes for the clipboard escape, this allows copying more text. Fixes #1002.
* Remove C1 escape supportChristian Duerr2019-12-31
| | | | Fixes #2981.
* Fix `OSC 52` with empty clipboard paramChristian Duerr2019-11-28
| | | | | | | | | This fixes the behavior of the clipboard escape (`OSC 52`) when the second parameter is not specified. If it is missing, the parameter is now assumed to be `c`, defaulting to the default clipboard. This has been fixed both for writing and reading. Fixes #3037.
