* 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.
* 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.
* 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.
* Add support for colon separated SGR parametersChristian Duerr2020-08-07
| | | | | This implements the colon separated form of SGR 38 and 48. Fixes #1485.
* Add regex scrollback buffer searchChristian Duerr2020-07-09
| | | | | | | | | | 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.
* Fix saved cursor handlingChristian Duerr2020-07-06
| | | | | | | | | | | 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.
* Preserve linewrap flag across alt screen switchesChristian Duerr2020-07-06
| | | | | | 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.
* Fix scroll down escape pulling lines from historyChristian Duerr2020-06-25
| | | | | | | | | | | | | | | | | This works around a bug where the optimized version of the `Grid::scroll_down` function would just rotate the entire grid down if the scrolling region starts at the top of the screen, even if there is history available. Since rotations of scrolling regions should not affect the scrollback history, this optimized version is now only called when the max scrollback size is 0, making it impossible for the grid to have any history while it is used. Since the main usecase of this is the alternate screen buffer, which never has any history, the performance should not be affected negatively by this change. Fixes #3582.

* Refactor Term/Grid separationChristian Duerr2020-05-30
| | | | | | | | | | | 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`.

* Remove `fs::read_to_string` reimplementationsChristian Duerr2020-03-26
| | | | | | After two previous PRs already removed some instances of reimplementations of the `fs::read_to_string` functionality, this removes the last remaining occurence and with it all instances of `File::open`. So this should remove them all for good.

* Add ref test for verifying colored clear behaviorChristian Duerr2019-11-10
| | | | | | | This covers the behavior of clearing the screen and a row with colored cells. This covers a bug discovered in #2329 which was not detected in any existing ref tests.
* Update to winit/glutin EventLoop 2.0Christian Duerr2019-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Ignore unsupported CSI sequencesKoichi Murase2019-08-06
| | | | | | | | Instead of ignoring unexpected intermediates in CSI escape sequences, the intermediates are now explicitly checked and the escape sequence is rejected when an unexpected intermediate is found. Fixes #2171.
* Remove color from log outputChristian Duerr2019-08-01
| | | Fixes #2474.
* Fix row occ not set during new and resetChristian Duerr2019-07-10
| | | | | | | | | | 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.
* Refactor config parsing filesChristian Duerr2019-05-10
| | | | | | | | This is a large refactor of the config parsing structure, attempting to reduce the size of the file a bit by splitting it up into different modules with more specific purposes. This also fixes #2279.
* Switch from copypasta to rust-clipboardChristian Duerr2019-04-28
| | | | | | | | | | | This switches our own `copypasta` crate with the more standardized `clipboard` library, which allows us to get rid of the `xclip` dependency on X11. Additionally, this lays the foundation for native Wayland clipboard support once the clipboard crate is updated (or a fork is created). Fixes #5.
* Split alacritty into a separate cratesTheodore Dubois2019-04-28
The crate containing the entry point is called alacritty, and the crate containing everything else is called alacritty_terminal.
