2023-11-10Remove `alacritty_config` from alacritty_terminalKirill Chibisov
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.

2023-05-17Update bitflags to 2.2.1Kirill Chibisov
2023-03-19Fix `;` character in URI OSC 8 payloadKirill Chibisov
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.
2022-07-24Fix inverted condition for cell's extra clearingKirill Chibisov
Fixes #6215.
2022-07-10Add support for hyperlink escape sequenceKirill Chibisov
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.
2022-03-16Add colored underline supportKirill Chibisov
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.
2022-02-14Add support for dashed and dotted underlinesKirill Chibisov
This finishes implementation of underline styles provided by `CSI 4 : [1-5] m` escape sequence.
2022-02-08Add support for drawing undercurlsKirill Chibisov
Fixes #1628.
2021-04-29Fix replacement of fullwidth charactersChristian Duerr
Fixes #3726.
2021-03-30Unify the grid line indexing typesChristian Duerr
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.

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.
2020-08-12Add 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.
2020-07-09Add 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.
2020-06-06Remove copyright notice from filesChristian Duerr
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.
2020-05-30Refactor Term/Grid separationChristian Duerr
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`.

2020-01-09Fix cut off full width glyphs in last columnChristian Duerr
This resolves the issue with full width glyphs getting rendered in the last column. Since they need at least two glyphs, it is not possible to properly render them in the last column. Instead of rendering half of the glyph in the last column, with the other half cut off, an additional spacer is now inserted before the wide glyph. This means that the specific glyph in question is then three cells wide. Fixes #2385.
2019-12-10Fix colored row reset performanceChristian Duerr
This fixes a bug where a row would always get reset completely if its background does not equal the default terminal background. This leads to big performance bottlenecks when running commands like `echo "\e[41m" && yes`. Instead of resetting the entire row whenever the template cell is not empty, the template cell is now compared to the last cell in the row. The last cell will always be equal to the previous template cell when `row.occ < row.inner.len()` and if `occ` is equal to the row's length, the entire row is always reset anyways. Fixes #2989.
2019-11-17Fix cell reset not clearing flags and foregroundKirill Chibisov
Fixes #2330.
2019-10-05Update to winit/glutin EventLoop 2.0Christian Duerr
This takes the latest glutin master to port Alacritty to the EventLoop 2.0 rework. This changes a big part of the event loop handling by pushing the event loop in a separate thread from the renderer and running both in parallel. Fixes #2796. Fixes #2694. Fixes #2643. Fixes #2625. Fixes #2618. Fixes #2601. Fixes #2564. Fixes #2456. Fixes #2438. Fixes #2334. Fixes #2254. Fixes #2217. Fixes #1789. Fixes #1750. Fixes #1125.

2019-07-10Fix row occ not set during new and resetChristian Duerr
Since ref tests were only stored whenever winit requested the window close, they would not get stored properly when the terminal was closed through Alacritty using `exit`, Ctrl+D or similar. This moves the ref test code to the and of the main entry point, which will always be executed regardless of how the terminal was shutdown. Fixes #2613.
2019-04-28Split alacritty into a separate cratesTheodore Dubois
The crate containing the entry point is called alacritty, and the crate containing everything else is called alacritty_terminal.
