* 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.
* Fix feature checking in cross buildsKirill Chibisov2020-10-10
| | | | | Checking for target os in build.rs doesn't work, since build.rs is running for host, so checking should be done in src. Thus moving 'compile_error!' check from build.rs to main.rs.
* Bump glutin to 0.25.0Kirill Chibisov2020-10-07
| | | | | | | | | | | | Fixes #4206. Fixes #4162. Fixes #4017. Fixes #3998. Fixes #3831. Fixes #3782. Fixes #3708. Fixes #2734. Fixes #2714. Fixes #1801.
* Fix non-ascii message bar text width calculationAlessandro Menezes2020-10-04
| | | | | | | | | | | | | | | | When formatting text for display in the message bar, Alacritty was using the byte length of the text instead of the glyph count. This lead to unnecessary blank space at the end of lines due to overestimation of their length. There also were no extra spaces inserted after fullwidth characters, leading to Alacritty giving them only a single cell of space. In line with the rest of Alacritty's rendering, a wide char spacer whitespace is now inserted in the message bar after glyphs which should occupy two cells. Fixes #4250.

* 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.

* Fix IME position with fullwidth chars in searchChristian Duerr2020-09-25

* Log new padding and cell size on 'SizeInfo' updateKirill Chibisov2020-09-24
| | | | This makes our logging of 'SizeInfo' changes more consistent with the one we're using when creating a new 'Display'.
* Fix CLI arguments without config fileChristian Duerr2020-09-20
| | | | | | | | | | | Since we only applied the CLI arguments as overrides to the configuration file after the file was loaded, all CLI arguments that are stored on the config would be dropped without a configuration file in place. This also makes sure that all configuration file config overrides are still loaded if the configuration file could not be loaded for any reason, since there's no reason why we'd just drop everything in that case.

* Fix multiline URL highlightingChristian Duerr2020-08-30
| | | | Fixes #4182.
* 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.
* Unify term dimension callsChristian Duerr2020-08-25
| | | | | | | Since the `Term` implements the `Dimensions` trait itself, we shouldn't call `term.grid()` to call methods from the `Dimensions` trait. This removes all instances of this that I could find in the code at the moment.
* Add CLI parameter to override config optionsChristian Duerr2020-08-22
| | | | | | | | This uses the facilities added in 3c3e6870dedad56b270f5b65ea57d5a6e46b1de6 to allow overriding individual configuration file options dynamically from the CLI using the --options/-o parameter. Fixes #1258.
* Fix config import error handlingChristian Duerr2020-08-22
|
* 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.
* Add logging for crossfontChristian Duerr2020-08-14
| | | | This refactors the logging function to clean things up a little bit and also adds the ability to see log messages for the `crossfont` library.
* Fix selection scrolling with message bar visibleChristian Duerr2020-08-14
| | | | | | | This resolves an issue with selection scrolling which would cause the selection to wrap to the top of the screen once the cursor enters the padding below the message bar. Fixes #4120.
* Use yellow/red from the config for message bar colorsKirill Chibisov2020-08-13
| | | | | | | | | | | | This commit completes the effort to use config colors for message bar content by picking red/yellow from user's colors.normal.{red,yellow} for error/warning messages instead of fixed colors. It also removes alacritty_terminal::term::color::RED and alacritty_terminal::term::color::YELLOW from the alacritty_terminal API, bumping its version to 0.11.0-dev. Fixes #4116.
* Use user's background color for render timer textKirill Chibisov2020-08-13
| | | | | Using the user's background color in pair with red should provide better contrast.
* 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.

* Fix characters swallowed during searchChristian Duerr2020-08-09
| | | | This resolves a bug where characters get swallowed when pressing them after pressing backspace before the backspace key is released.

* Use `tcgetpgrp` to get PID for SpawnNewInstanceChristian Duerr2020-08-06
| | | Fixes #4082.
* Reduce InstanceData footprintJoe Wilm2020-08-05
| | | | | | | | | | | | | | | | | | | | | | | | The InstanceData type in the rendering subsystem was previously 17 f32s plus one u8 which occupied a total of 72 bytes per instance. This meant that for every character or background cell drawn, 72 bytes were sent to the GPU. In the case of a 400x100 cell grid, a total of 2.9MB would be sent. This patch reduces InstanceData's size to 36 bytes, a 50% improvement! Using the above example for comparison, a worst case of 1.44MB would be transferred. The motivation for this patch comes from macOS. Once the terminal grid would reach a certain size, performance experienced a sharp and dramatic drop (render times would go from ~3ms to ~16ms). I don't want to speculate too much on the underlying issue, but suffice it to say that this patch alleviates the problem in my testing. While the performance impact was most significant on macOS, with rendering times cut by more than 50% in some cases, this also results in a measurable performance difference on other systems with high density grids.

* Fix negative window positionChristian Duerr2020-08-02
| | | | | | | This resolves an issue where negative window positions set in the configuration file would not place the Alacritty window in the correct location. Fixes #4061.
* Fix crates.io publishing restrictionsChristian Duerr2020-08-01
| | | | This works around the problem that crates pushed to crates.io cannot reference files outside of their crate directory.
* Bump minimum supported Rust version to 1.43.0Kirill Chibisov2020-07-28

* Fix scrolling with selection expansionChristian Duerr2020-07-27
| | | Fixes #4040.
* Fix viless search originChristian Duerr2020-07-25
| | | | | | | | | | | | | When searching without vi mode the display is no longer reset when the user hasn't jumped between matches at all. Since there's no reason to confirm the search, we shouldn't just reset the viewport without a good reason. The search is now also restarted completely when the entire search regex is deleted. While this doesn't reset to the original viewport position if the user has jumped between matches, it should make things feel a little less arbitrary. Fixes #4020.
* Rename font crate to crossfontChristian Duerr2020-07-18

* Fix crashes during searchChristian Duerr2020-07-17
| | | | | | | | | | | | | | | | This fixes two crashes related to search. The first crash was due to variable shadowing computing the incorrect length of a search as soon as it was started, causing an overflow after attempting a subtraction. Since overflows are only debug mode checks, in release this would lead to an IME positioned far, far beyond the window's boundaries (likely offscreen). The other bug was that the search was always started from the last column in reverse search without vi mode, but after shrinking the terminal width that origin point is no longer a valid part of the grid. As a result it would cause an index out of bounds. The line was already clamped to the grid, but now the same is also done for the column. Fixes #3987.

* Fix selection update in viless searchChristian Duerr2020-07-17
|
* Add support for searching without vi modeChristian Duerr2020-07-15
| | | | | | | | This implements search without vi mode by using the selection to track the active search match and advancing it on user input. The keys to go to the next or previous match are not configurable and are bound to enter and shift enter based on Firefox's behavior. Fixes #3937.
