2020-12-05Fix dimming of indexed colorsChristian Duerr
It seems like the list of colors might have changed a bit, leading to indexed colors not being transformed into their dim colors correctly. To prevent this from happening in the future, the dimming for colors in the range '0..=7' is now performed by offsetting them from the 'NamedColor::DimBlack'. Since this is the first dimmed color, this should always work as long as all dimmed colors are added in the correct order.
2020-11-28Draw selection below Vi cursor when it's hiddenKirill Chibisov
2020-11-26Fix DoS caused by excessive CSI parameter valuesChristian Duerr
2020-11-23Add blinking cursor supportDettorer
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.
2020-11-19Fix vi mode terminal resetChristian Duerr
Since the vi mode is unrelated to the terminal emulation itself, it should not be reset during a `reset` to prevent unnecessary confusion. This also prevents the search from switching from vi mode to vi-less search without any indication to the user.
2020-11-17Fix wide characters being cut offKirill Chibisov
Fixes #791.
2020-11-15Bump development version to 0.7.0-devChristian Duerr
This is only an update to the development version and does not represent a stable release.
2020-11-15Fix zerowidth characters in the last columnKirill Chibisov
This commit fixes the issue that when attempting to write zerowidth characters into the last column, it is written in the second to last column instead. Fixes #4227. Co-authored-by: Christian Duerr <contact@christianduerr.com>
2020-11-13Update vte to 0.9.0Christian Duerr
2020-11-13Add ability to select text during searchChristian Duerr
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.
2020-11-13Fix use after free when dropping zerowidth dataKirill Chibisov
Commit ec42b42ce601808070462111c0c28edb0e89babb added an optional pointer for each cell, thus some old code that was optimizing copying with 'ptr::copy' was duplicating "unique" pointers ('Box'), which was resulting in use after free, after attempting to free both of these pointers. By replacing these unsafe blocks with safe Rust, the issue itself is fixed and the potential for future memory problems is eliminated from this area of the code.
2020-11-06Deprecate the WinPTY backendChristian Duerr
2020-11-05Use dynamic storage for zerowidth charactersChristian Duerr
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.
2020-10-29Error on warnings when running clippyKirill Chibisov
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'.

2020-10-10Add support for urgency hints CSITaylor Blau
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.
2020-10-07Bump glutin to 0.25.0Kirill Chibisov
Fixes #4206. Fixes #4162. Fixes #4017. Fixes #3998. Fixes #3831. Fixes #3782. Fixes #3708. Fixes #2734. Fixes #2714. Fixes #1801.
2020-09-27Add support for single line terminalsii41
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.

2020-09-26Fix selection incorrectly expanding when scrolled in historyKirill Chibisov
When doing selection expansion we were checking for wide char flags on a cells from the bottom of the terminal instead of in a current viewport when scrolled up in history, which was leading to expanding more than needed if we had wide chars on the same viewport cell, but in the bottom of the terminal. Fixes #4257.

2020-08-28Add escape to report text area sizeAyose Cazorla
This implements the escapes `CSI 14 t` and `CSI 18 t` which report the text area size in pixels and characters.
2020-08-25Unify term dimension callsChristian Duerr
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.
2020-08-21Add configuration file importsChristian Duerr
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.
2020-08-13Use yellow/red from the config for message bar colorsKirill Chibisov
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.
2020-08-12Add support for double underlinesChristian Duerr
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.
2020-08-12Fix handling of wrapline flag in last lineChristian Duerr
This resolves an issue where Alacritty would crash when a wrapline flag was present in the last column of the last line. While it should not be possible to achieve this with normal text flow, it is possible to rotate the content downwards using the `CSI Ps T` escape, causing this bug to occur. This also works around other issues like the vi cursor jumping to the top of the screen when trying to move beyond the last column using the `l` key. In debug mode this even lead to a crash due to the overflow. Fixes #4109.
2020-08-07Add support for colon separated SGR parametersChristian Duerr
This implements the colon separated form of SGR 38 and 48. Fixes #1485.
2020-08-06Use `tcgetpgrp` to get PID for SpawnNewInstanceChristian Duerr
Fixes #4082.
2020-07-28Bump minimum supported Rust version to 1.43.0Kirill Chibisov
2020-07-27Fix CellForeground and CellBackground cursor colorsKirill Chibisov
This commit fixes regression introduced in bedf5f3004e8f33011925ca471be02ead96f4581, when setting certain CellForeground/CellBackground combinations stoppped working.
2020-07-26Invert fixed color cursor if it's close to cell bgChristian Duerr
This should reduce the number of times people with fixed cursor colors run into troubles when existing text is already colored. Using just the background color as a metric instead of both background and foreground color should ensure that the cursor still has a clear shape, since just changing the foreground color for a cursor might be difficult to see. Always inverting the entire cursor instead of keeping the fixed foreground color is important to make sure the contrast isn't messed up. Fixes #4016.
2020-07-23Add secondary DA supportChristian Duerr
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.
2020-07-19Bump version to 0.6.0-devChristian Duerr
2020-07-19Bump alacritty_terminal versionChristian Duerr
This change bumps the version of the `alacritty_terminal` crate to force it out of sync with the Alacritty application. Since it is a library that will be published on crates.io, it should be following semver rather than our binary's release version. While it would be possible to just keep it at 0.5.0, explicitly disconnecting it from the Alacritty version should give it a clean starting-off point and prevent unnecessary confusion. Bumping it to 0.10.0 instead of something like 0.6.0 should allow for a nice gap between the different versions without being too arbitrary. Changing the version to 0.1.0 is not an option since decreasing semver version would likely cause a lot of problems. While it would be possible to further separate the Alacritty terminal library from the Alacritty terminal emulator, by renaming it from `alacritty_terminal` to something different, I don't think that is necessary or a good idea at the moment. Even though the `alacritty_terminal` library *can* be used for other terminals, its primary goal is still to support the Alacritty terminal emulator and I don't see that changing. So making that clear in its name seems like a good idea. Since there is no plan to maintain this library separately from Alacritty, but to keep both tied together, the naming should reflect this.
2020-07-15Add support for searching without vi modeChristian Duerr
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.
2020-07-15Fix cursor reflowChristian Duerr
This resolves three different issues with cursor reflow. The first issue was that the cursor could reach the top of the screen during reflow, since content was pushed into history despite viewport space being available. Since the cursor cannot leave the viewport, this would insert new space between the cursor and content (see #3968). Another issue was that the wrapline flag was not set correctly with content being available behind the cursor. Since the cursor is not necessarily at the end of the line, it is possible that the cursor should reflow to the next line instead of staying on the current one and setting the wrapline flag. The last bug fixed in this is about reflow with content available behind the cursor. Since that might have en effect on new lines being inserted and deleted below the cursor, the cursor needs to be reflown based on it. Fixes #3968.
2020-07-14Fallback to SHELL instead of passwd if presentMattbazooka
Instead of just always falling back to the shell specified in the passwd file when no config or cli shell was specified, Alacritty will not first look at the `$SHELL` environment variable. If this is unset, it will still read the passwd file. Since macOS is a bit peculiar and does not set the `$SHELL` environment variable by default, it is set manually to the shell used by Alacritty while any existing `$SHELL` variables are ignored. This matches the behavior of iTerm and Terminal.app. Co-authored-by: Christian Duerr <contact@christianduerr.com>
2020-07-14Fix crash on cursor resizeChristian Duerr
Fixes #3960.
2020-07-11Remove gui dependencies from alacritty_terminalKirill Chibisov
This commit removes font dependency from alacritty_terminal, so it'll simplify the usage of alacritty_terminal as a library, since you won't link to system's libraries anymore. It also moves many alacritty related config options from it. Fixes #3393.
2020-07-10Add option to run command on bell Kirill Chibisov
Fixes #1528.
2020-07-10Fail compilation if Fontconfig is not installed on Linux/BSDKirill Chibisov
Statically linking Fontconfig was leading to slow startup and various errors, so forcing the use of system's library.
2020-07-09Add regex scrollback buffer searchChristian Duerr
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.
2020-07-09Fix cursor reflowChristian Duerr
To make sure that output is consistent even while resizing the window, the cursor will now reflow with the content whenever the window size is changed. Since the saved cursor is more likely to represent a position in the grid rather than a reference to the content below it and handling of resize before jumping back to it is more likely than with the primary cursor, no reflow is performed for the saved cursor The primary cursor is unfortunately always reflowed automatically by shells like zsh, which has always caused problems like duplicating parts of the prompt and stretching it out "infinitely". Since the cursor is now reflowed appropriately the duplication of the shell prompt should be reduced, however it is possible that the shell moves the cursor up one line after it has already been reflowed, which will cause a line of history to be deleted if there is no duplicated prompt line above the reflowed prompt. Since this behavior is identical in VTE and Kitty, no attempt is made to work around it in this patch. Fixes #3584.
2020-07-06Fix saved cursor handlingChristian Duerr
This resolves several problems with handling of the saved cursor when switching between primary and alternate screen. Additionally ref-tests are also added for all common interactions to make sure the behavior does not regress. The behavior is based on XTerm's behavior except for interaction with `reset`. XTerm does not reset the alternate screen's saved cursor on `reset`, but VTE does. Since a `reset` should reset as much as possible, Alacritty copies VTE here instead of XTerm.
2020-07-06Preserve linewrap flag across alt screen switchesChristian Duerr
While neither VTE, URxvt nor Kitty handle this, preserving the linewrap flag across alternate screen switches seems like the correct thing to do. XTerm also does handle this correctly, which indicates that it is a bug and not a feature.
2020-07-03Document supported escape sequencesChristian Duerr
Fixes #3440.
2020-07-01Fix reflow of empty wrapped cursor lineChristian Duerr
This bug was caused by trying to grow the terminal while the cursor line was wrapped but entirely empty. Resizing the terminal now accounts for the position of the deleted line and moves the cursor up only when the line deleted was above it. The deletion of the line was caused by the shell redrawing itself whenever the cursor is moved. Fixes #3583.
2020-06-29Fix foreground dimming with truecolor textCarlo Abelli
Fixes #3766.
