* Fix crash when searching during resetChristian Duerr2022-03-10
| | | | | | | | | | | | | | | | | | This fixes a crash which occurs when the terminal is reset while searching, due to the vi mode cursor being outside of the visible area. This also fixes an issue where the search state reset would incorrectly clamp the vi mode cursor to the grid, rather than the absolute viewport position. While this fix does resolve all crashes when searching while running `cat /dev/urandom`, it does raise the question if manually clamping the vi mode cursor in every location where it is modified is the right choice. A follow-up to provide a safer API which guarantees correct modification of the vi mode cursor location is probably a good idea. Fixes #5942.
* Fix line indicator damage computationKirill Chibisov2022-03-10
| | | | The starting point of damage should be computed from the right side of the terminal, not from the starting point of line indicator.
* Use round instead of ceil for line positionKirill Chibisov2022-03-06
| | | | Ceiling line position results in strikeout line being lower than it should.
* Add fallback GLES2 rendererKirill Chibisov2022-03-02
| | | | | | | | | | | | | | | | | | | | | Currently Alacritty only works on hardware which supports OpenGL 3.3 or more, which can become problematic with older devices. This patch adds a new GLES2 renderer, since it is much more widely supported, especially on weaker hardware like phones or a Raspberry Pi. While the GLES2 renderer is slower than the OpenGL 3.3+ version, it is still significantly faster than software rendering. However because of this performance difference it is only used when necessary and there should be no difference for machines supporting OpenGL 3.3+. The two renderers are largely independent and separated in the `renderer/text/glsl3` and `renderer/text/gles2` modules. Separate shaders are also required for text rendering. The rectangle rendering for underlines and the visual bell works identically for both versions, but does have some version-specific shader code. Fixes #128.

* Don't load font twice during display creationKirill Chibisov2022-02-18
| | | | | This commit finishes the effort from a64553b to avoid reloading font twice during startup, since the original issue is with getting font metrics without building the glyph cache.
* Account for absolute WAYLAND_DISPLAY pathsmahkoh2022-02-16
| | | | If WAYLAND_DISPLAY contains a '/', we have to replace with with another character before using WAYLAND_DISPLAY as a path component.
* Reuse Rasterizer in Display::newGreg Depoire--Ferrer2022-02-16
| | | | | | | Instead of creating a `Rasterizer` to guess the window dimensions, dropping it and then creating a new one for the glyph cache, reuse the same `Rasterizer`. This prevents the font from being loaded twice during startup.
* 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.
* Clear damage rects right after drawingKirill Chibisov2022-02-11
| | | | Since we could queue damage before we get into the actual rendering we should clear it after drawing not before.
* Fix terminal not being damage when only font size changedKirill Chibisov2022-02-10
| | | | | If font size changes however the cells stay the same the terminal won't be damaged, since it wasn't resized, however the visual change happened, thus the entire screen should be damaged.
* Add version to info logChristian Duerr2022-02-09

* Fix warnings when building only with Wayland featureKirill Chibisov2022-02-09
| | | | This commit also makes our CI fail hard when warning encountered when building only for either Wayland or X11.
* Add support for drawing undercurlsKirill Chibisov2022-02-08
| | | Fixes #1628.
* Fix renderable_cursor method documentationThomas Churchman2022-02-03
| | | | | This method no longer returns an `Option` since #5773. Co-authored-by: Kirill Chibisov <contact@kchibisov.com>
* Fix builtin font block elements going invisibleKirill Chibisov2022-02-03

* Fix terminal damage after leaving Vi modeKirill Chibisov2022-02-02
| | | | This fixes an issue when search results were not damaged when leaving Vi mode.
* Add damage tracking and reporting to compatible compositorsKirill Chibisov2022-02-02
| | | | | | | | | | | | | | This allows compositors to only process damaged (that is, updated) regions of our window buffer, which for larger window sizes (think 4k) should significantly reduce compositing workload under compositors that support/honor it, which is good for performance, battery life and lower latency over remote connections like VNC. On Wayland, clients are expected to always report correct damage, so this makes us a good citizen there. It can also aid remote desktop (waypipe, rdp, vnc, ...) and other types of screencopy by having damage bubble up correctly. Fixes #3186.

* Use cell width to compute builtin font thicknessKirill Chibisov2022-01-30
| | | | | | | | | | | While using underline thickness could sound logical to draw other lines most fonts don't make underlines thick compared to cell bounding box if you increase font size. So instead we're using cell width to scale builtin font nicely. This commit also adjusts arcs drawing and alignment. Fixes #5826. Fixes #5821.
* Log used display server on Linux/BSDKirill Chibisov2022-01-30
| | | This also fixes a bug where the welcome log message wasn't logged.
* Account for font.offset and glyph.offset in built-in fontKirill Chibisov2022-01-29
| | | | This commit takes into account `font.offset` and `font.glyph_offset` when generating built-in font.
* Add option to control built-in box drawing charszandr2022-01-29
| | | | | This commit adds the config `font.builtin_box_drawing` option to control built-in font, which is enabled by default.

* Remove time dependencyChristian Duerr2022-01-13
| | | | | | | | | | | | | | | | In 7398e9f a regression was introduced which causes Alacritty to crash on startup since wayland has a keyboard repeat rate thread started before our logger is initialized. Since the latest version of time was rather inconvenient to use anyway and there is no nice solution for this issue other than downgrading the `time` version again, the time since startup is now logged instead of the local time. This should still provide all the relevant information, while getting rid of an unnecessary dependency. While it would be possible to also print the delta between log messages, this can be trivially computed so it has been omitted to skip adding another `Mutex` to the `Logger` struct.
* Update time crate to 0.3.5James McCoy2022-01-13
| | | | | | | Due to unsoundness issues (c.f., time-rs/time#380 and time-rs/time#293), determining the local timezone can only happen while single-threaded. Determine the timezone early in startup and apply the offset to the UTC timestamp before formatting.
* Don't blink when cursor is hiddenKirill Chibisov2022-01-11
| | | | This prevents unnecessary redraws when the terminal is idle, cursor is hidden and blinking is enabled.
* Use `with_position` instead of `set_outer_position`Kirill Chibisov2022-01-11
| | | | This uses `with_position` method on a `WindowBuilder` instead of setting window position on the created window later on.
* Fix block selection expansion with Ctrl + RMBKirill Chibisov2022-01-11
| | | | | | When 'ExpandSelection' binding was added only default binding for RightClick was added, however to expand block selection holding control when doing a click is required, so this commit adds a binding for 'RMB + Control'.
* Fix title setting via IPC when dynamic_title is enabledKirill Chibisov2022-01-06

* Use builtin font for box drawing unicode charactersKirill Chibisov2022-01-06
| | | | | | | | | | | | This commit adds hand rolled drawing of unicode box drawing[1] and block elements[2] from ranges U+2500 up to U+259f. While using system font for such characters will look better most of the time, the characters tend to overlap or not align, so providing builtin font is the lesser evil here. [1] - https://www.unicode.org/charts/PDF/U2500.pdf [2] - https://www.unicode.org/charts/PDF/U2580.pdf Fixes #5485.
* Migrate from structopt to clap 3Christian Duerr2022-01-04

* Add title/class CLI parameters to create-windowKirill Chibisov2022-01-03
| | | | | This adds the ability to pass title and class over IPC via the create-window subcommand, so users can run only one instance for windows of different spurposes in the window managers of their choice.
* Fix test failures due to CLI parametersChristian Duerr2021-12-25
| | | Fixes #5717.
* 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.
* Remove shared PID/FD variablesChristian Duerr2021-12-19
| | | | | | | | | | | | | | | | The existing PID/FD atomics in alacritty_terminal/src/tty/unix.rs were shared across all Alacritty windows, causing problem with the new multiwindow feature. Instead of sharing these between the different windows, the master FD and shell PID are now stored on the `window_context`. Unfortunately this makes spawning new daemons a little more complicated, having to pass through additional parameters. To ease this a little bit the helper method `spawn_daemon` has been defined on the `ActionContext`, making it accessible from most parts of Alacritty's event loop. Fixes #5700.
* Spawn children from foreground working directoryJorge Carrasco2021-12-18
| | | | | | | | | To allow applications spawned by Alacritty to make use of the shell/foreground process' working directory, it is now set for all new processes spawned by Alacritty on Unix platforms. Fixes #5616. Co-authored-by: Christian Duerr <contact@christianduerr.com>
* Bump glutin to 0.28.0Kirill Chibisov2021-12-03
| | | | | | | | Fixes #5603. Fixes #5422. Fixes #5350. Fixes #4105. Co-authored-by: Christian Duerr <contact@christianduerr.com>
* 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.
* Switch to clap-generated completionsChristian Duerr2021-11-19
| | | | | | | | | | | | | | | The current completions required a lot of domain-specific knowledge about each individual shell and their completion functionality. Much of which is sparsely documented. While clap does not generate perfect completions, since parameters like `-e` are missing completions, it does a reasonable job while requiring no work on writing these completions. Since access to `cli.rs` isn't possible from the `build.rs`, these completions aren't always generated on build. Instead a test verifies that there has been no changes to these completions and provides a simple code sample for re-generating them. This should provide a simple solution with minimal overhead.
* Fix crash with empty post-processed matchesScott Freeman2021-11-11
| | | | | Fixes #5492. Co-authored-by: Christian Duerr <contact@christianduerr.com>
* Fix libxkbcommon-devel package name for openSUSEDiego Garza2021-11-02
| | | Fixes #5586.
* 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 cursor inversion logicChristian Duerr2021-10-22
| | | | | | | | | | | | The existing cursor inversion logic was causing more problems than it solved, without solving the problem of invisible cursor when inverting a cell with matching foreground and background colors. This patch reworks this logic and only inverts the cursor when the foreground and background colors of the cursor are similar and the cursor colors aren't set to fixed RGB values. Fixes #4564. Fixes #5550.
* Update rustfmt configurationChristian Duerr2021-10-11
| | | | | | | | | | | | | | | | | In this change I went through all current rustfmt configuration options and expanded our existing configuration with overrides whenever deemed appropriate. The `normalize_doc_attributes` option is still unstable, but seems to work without any issues. Even when passing macros like `include_str!` that is recognized properly and not normalized. So while this wasn't an issue anywhere in the code, it should make sure it never will be. When it comes to imports there are two new major additions. The `imports_granularity` and `group_imports` options. Both mostly just incorporate unwritten rules that have existed in Alacritty for a long time. Unfortunately since `alacritty_terminal` imports in `alacritty` are supposed to be separate blocks, the `group_imports` option cannot be used.
