* Fix damage tracking on WaylandChristian Duerr2021-01-27
| | | | | | | Since the Wayland event loop might delay rendering across event loop callback executions, it's necessary to track the global damage globally rather than just within a single loop execution. Fixes #4736.
* 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.

* Fix jumping between matches in reverse vi searchChristian Duerr2021-01-08
| | | Fixes #4676.
* Fix inefficient search initializationChristian Duerr2021-01-07
| | | | | | The creation of the renderable search iterator was doing a lot of work even when absolutely no search is active at the moment. To resolve this problem, an early return now makes sure that a search is active before going through the trouble of creating an iterator for it.
* Fix debug mode crash in vi-less searchChristian Duerr2021-01-03
|
* Fix movement between matches in vi-less searchChristian Duerr2021-01-01
| | | | | | | | | | | | | | | This resolves various bugs related to vi-less search. The primary issue was that when jumping between matches more than 1000 lines apart, the search would get stuck and not advance between matches properly due to the 1000 line synchronous search limit. Some other issues related to the tracking of the search origin have also been fixed, improving the viewport positioning while interacting with the search outside of vi mode. This was done by keeping the search origin outside of the viewport, which allows for search to start right at the first character. Previously the search was on top of the first character which lead to it being excluded from search. Fixes #4626.
* Add vi/search line indicatorChristian Duerr2021-01-01
| | | | | | | | | This adds a new visual indicator which shows the position in history of either the display offset during search, or the vi mode cursor. To make it as unintrusive as possible, the overlay is hidden whenever the vi mode cursor collides with its position. Fixes #3984.
* Remove Windows WinPTY backendChristian Duerr2021-01-01
|
* 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.
* Add default binding to cancel search on Ctrl+CChristian Duerr2020-12-31
| | | Fixes #4612.
* Fix characters getting swallowed during IME inputChristian Duerr2020-12-31
| | | | | | | | This reverts 1d00883 since it is not necessary anymore after all search bindings are now proper key bindings. This fixes a bug which would cause the first character to be swallowed when using IME after triggering any key binding which doesn't send any `ReceivedCharacter` event. Fixes #4588.
* Fix missing glyphs crash on WindowsChristian Duerr2020-12-29
| | | Fixes #4617.
* Draw cursor with rect rendererKirill Chibisov2020-12-28
| | | | | | | | This commit makes cursors being drawn via rects, thus it's always above underlines/strikeouts. Also, since the cursor isn't a glyph anymore, it can't be obscured due to atlas switching while glyphs are rendered. Fixes #4404. Fixes #3471.
* Hide "missing" glyp for zerowidth characterKirill Chibisov2020-12-23
| | | | | | | | | | | This patch prevents missing zerowidth glyphs from obscuring the rendered glyph of a cell. The missing glyph itself is also consistently loaded and displayed on all platforms. It is initialized once together with the ascii symbols and then written to the atlas only once for every cached missing glyph. Co-authored-by: Christian Duerr <contact@christianduerr.com>
* Disable shadows for transparent windows on macOSChristian Duerr2020-12-22
| | | | | | | | | | | | Commit 5725f58 introduced a performance regression on macOS due to excessive calls to the `invalidateShadow` function, however calling this function only on redraw after a resize was performed does not fix the underlying problem. As a solution, window shadows are now disabled completely for all transparent windows. This makes sure there is no performance impact, while still solving the problem with text artifacts on resize. Fixes #4604.
* Fix artifacts on macOS with transparent windowsChristian Duerr2020-12-21
| | | | | | | | | | | Due to the way macOS draws shadows for transparent windows, resizing them will lead to text artifacts remaining present after a window has been resized. The `invalidateShadow` call is used whenever the opacity isn't `1.0` to make sure these shadows are cleared before redrawing, so no artifacts remain when resizing transparent windows. Fixes #889.
* 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.
* Fix embedded _NET_WM_ICON on X11Christian Duerr2020-12-20
| | | | | | | | | | Previously the _NET_WM_ICON would use the .ico which was also used for the Windows icon. This icon used the dimensions 256x256, but the maximum supported image size is 192x192, so a new image with the dimensions 64x64 has been added. Since we know the image format anyways, the `image` dependency could also be easily replaced with `png`, which cuts out a few extra unused dependencies.
* Add search history supportChristian Duerr2020-12-20
| | | | | | | | | | | | This adds a history to the regex search limited to at most 255 entries. Whenever a search is either confirmed or cancelled, the last regex is entered into the history and can be accessed when a new search is started. This should help users recover complicated search regexes after accidentally discarding them, or handle repeated searches with the same regexes. Fixes #4095.
* Add separate mode for search bindingsChristian Duerr2020-12-19

* Increase file watcher delay on BSDChristian Duerr2020-12-17
| | | | | | | | | | | Since BSD does not support inotify polling in the `notify` crate and instead relies on manual filesystem polling, this would cause a high CPU usage at 100 polls a second. A separate polling rate of once per second is now used for platforms which do not support filesystem polling, allowing users to still make use of live config reload on BSD. Fixes #3871.
* Fix live reload with broken yaml on startChristian Duerr2020-12-14
| | | | | | | | | | | | | Since the current behavior would just load the default configuration file whenever the configuration file couldn't be loaded, the path was not set to any value. As a result however, the live config reload feature would not work with a broken yaml (one which cannot be deserialized, not one with warnings). If a configuration file has been specified, but the deserialization still failed, the path is now preserved on the default configuration file to make it possible to live reload a fix for the issue. Fixes #4561.
* Fix cursor reports with mouse outside of windowChristian Duerr2020-12-13
| | | | | | | | | | | Previously Alacritty would not report cursor escapes to the application when a mouse button was held down and the mouse was moved. This prevents applications like tmux from updating their selection. Similarly to how windowing libraries keep reporting mouse events when the left mouse button is held down over the window, the escape sequences are now clamped to within the grid and reported to applications. Fixes #4566.
* Bump glutin to 0.26.0Kirill Chibisov2020-12-11
| | | | | Fixes #4530. Fixes #4072. Fixes #1927.
* Remove live-shader-reload featureKirill Chibisov2020-12-10
| | | | | Since live-shader-reload is generally unused and unmaintained, and could only be used for debugging purposes, since it refers relative paths, this feature was removed for the sake of simplicity.
* Print multiline logs in one write callKirill Chibisov2020-12-10
| | | | Fixes potential split of multiline logs in the multithreaded context by writing them all at once.
* Render underline and strikeout rects in batchesIvan Avdeev2020-12-10
| | | | | | | | | | | | | | | Currently Alacritty requires a separate `draw` call to OpenGL whenever a new rectangle is rendered to the screen. With many rectangles visible, this has a significant impact on rendering performance. Instead of using separate draw calls, the new `RectRenderer` will build a batch of rectangles for rendering. This makes sure that multiple rectangles can be grouped together for single draw calls allowing a reduced impact on rendering time. Since this change is OpenGL 2 friendly, it should not make it more complicated to transition away from the 3.3+ requirements like an alternative instancing based implementation might have.
* 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 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.
* Add support for '~/' in config importsChristian Duerr2020-11-24
| | | | | | | | | | | This allows the configuration file imports to start with '~/' and resolve relative to the user's home directory. There is no support for '~user/' or '$HOME/' or any other shell expansion. However since paths relative to the home directory should be sufficient for everything, this provides a very simple solution without any significant drawbacks. Fixes #4157.
* Increase font size in CSDs on WaylandKirill Chibisov2020-11-22
| | | | | Winit changed the default font size for CSDs from 17pt to 11pt, this patch reverts that since it is too small to be readable.
* Fix stdout log message orderKirill Chibisov2020-11-19
| | | | | | | | | This patch makes sure that the message for the creation of a log file is always the first entry, before any other log file messages. Since we initialize our log file dynamically, the message is printed as soon as something is written to it. By making sure that we always write to a file first and then try stdout, we can ensure that the log file is always initialized before ever writing log messages to stdout.
* Ignore nonexistent config imports instead of raising an errorJames Simpson2020-11-19
| | | Fixes: #4330.
* Fix wide characters being cut offKirill Chibisov2020-11-17
| | | Fixes #791.
* Feature gate 'image' when building without x11 featureKirill Chibisov2020-11-14
| | | | On Wayland there's no way to embed icon into the window, thus there's no point in loading it when x11 feature is disabled.
* Add ability to select text during searchChristian Duerr2020-11-13
| | | | | | | | | | | | | This removes the restriction of not being able to select text while the search is active, making it a bit less jarring of a UX when the user tries to interact with the terminal during search. Since the selection was used during vi-less search to highlight the focused match, there is now an option for a focused match color, which uses the inverted normal match color by default. This focused match is used for both search modes. Other mouse interactions are now also possible during search, like opening URLs or clicking inside of mouse mode applications.
* Spawn new alacritty processes in CWD on macOSNathan Lilienthal2020-11-07
| | | | | | On macOS we can use 'proc_pidinfo' to determine the working directory of the terminal foreground process. Fixes #1979.

* Use dynamic storage for zerowidth charactersChristian Duerr2020-11-05
| | | | | | | | | | | | | | | | | | | The zerowidth characters were conventionally stored in a [char; 5]. This creates problems both by limiting the maximum number of zerowidth characters and by increasing the cell size beyond what is necessary even when no zerowidth characters are used. Instead of storing zerowidth characters as a slice, a new CellExtra struct is introduced which can store arbitrary optional cell data that is rarely required. Since this is stored behind an optional pointer (Option<Box<CellExtra>>), the initialization and dropping in the case of no extra data are extremely cheap and the size penalty to cells without this extra data is limited to 8 instead of 20 bytes. The most noticible difference with this PR should be a reduction in memory size of up to at least 30% (1.06G -> 733M, 100k scrollback, 72 lines, 280 columns). Since the zerowidth characters are now stored dynamically, the limit of 5 per cell is also no longer present.
* Fix visual bell getting stuckChristian Duerr2020-10-30
| | | | | | | | This resolves a problem with the visual bell where it would not automatically trigger a redraw itself after the initial frame has been rendered. Since the unit of the visual bell duration is also unclear, it has been clarified.
* Fix crash with large negative font offsetChristian Duerr2020-10-29
| | | Fixes #4363.
* 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'.
* Fix build failure on macOS without featuresChristian Duerr2020-10-28
| | | Fixes #4353.
* Remove unneeded collect during line rect creationMark Lodato2020-10-22
|
* Check viewport size after initial resizeChristian Duerr2020-10-22
| | | | | Since the 'set_inner_size' call might immediately alter the window size, the query for the window's dimensions should be performed after the resize has been requested.
* Fix incorrect X11 feature checkChristian Duerr2020-10-12
| | | See https://github.com/alacritty/alacritty/commit/721f789b5f98ab5c47e6e817c3c2228636ca0a1a#r43183826.
* Make use of glutin wayland/x11 featuresKirill Chibisov2020-10-12
| | | | This should allow users that are not using Wayland/X11 to reduce the resulted binary size and compilation times.
* 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.
