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.
2022-09-01Add IPC config subcommandChristian Duerr
This patch adds a new mechanism for changing configuration options without editing the configuration file, by sending options to running instances through `alacritty msg`. Each window will load Alacritty's configuration file by default and then accept IPC messages for config updates using the `alacritty msg config` subcommand. By default all windows will be updated, individual windows can be addressed using `alacritty msg config --window-id "$ALACRITTY_WINDOW_ID"`. Each option will replace the config's current value and cannot be reset until Alacritty is restarted or the option is overwritten with a new value. Configuration options are passed in the format `field.subfield=value`, where `value` is interpreted as yaml. Closes #472.
2021-12-23Fix CreateNewWindow CLI fallbackChristian Duerr
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.
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.
2021-01-24Move renderable cell transformation to alacrittyChristian Duerr
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.
2020-12-31Use ConfigDeserialize for all config enumsChristian Duerr
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.
2020-12-28Draw cursor with rect rendererKirill Chibisov
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.
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.
2020-09-24Remove unused Linear newtype. (#4248)Nathan Lilienthal
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`.
2020-05-05Extend style guideline documentationChristian Duerr
2020-03-18Add modal keyboard motion modeChristian Duerr
This implements a basic mode for navigating inside of Alacritty's history with keyboard bindings. They're bound by default to vi's motion shortcuts but are fully customizable. Since this relies on key bindings only single key bindings are currently supported (so no `ge`, or repetition). Other than navigating the history and moving the viewport, this mode should enable making use of all available selection modes to copy content to the clipboard and launch URLs below the cursor. This also changes the rendering of the block cursor at the side of selections, since previously it could be inverted to be completely invisible. Since that would have caused some troubles with this keyboard selection mode, the block cursor now is no longer inverted when it is at the edges of a selection. Fixes #262.
2020-03-07Fix selection with invisible start and endChristian Duerr
This resolves an issue with the selection clamping, where no selection would be rendered at all when the start was above the viewport while the end was below it.
2020-02-07Fix selection expansion across full-width glyphsChristian Duerr
Instead of trying to expand the start and end of a selection across full-width glyphs, the selection should now only go from its origin to the end without any kind of expansion. Instead, the expansion is now done where the cells are actually checked for their selection status, expanding across the entire full-width glyph whenever any part of it is selected. Fixes #3106.
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.
2019-11-03Fix URL highlightingChristian Duerr
Fixes #2898. Fixes #2479.
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.
2019-08-01Switch to rfind_url for URL detectionChristian Duerr
This switches to rfind_url for detecting URLs inside the grid. Instead of expanding at the cursor position, the complete terminal is searched from the bottom until the visible region is left with no active URL. Instead of having the field `cur` publicly accessibly on the `DisplayIterator`, there are the two methods `DisplayIterator::point` and `DisplayIterator::cell` for accessing the current element of the iterator now. This allows accessing the current element right after creating the iterator. Fixes #2629. Fixes #2627.
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.
