* fix: Handle signals before crossterm events (#6170)Alexander Brevig2023-03-05
| | | | | | | | | | | This is a workaround for a freeze when suspending Helix with C-z on non-Windows systems. The check for the keyboard enhancement protocol locks up crossterm's internal event reading/polling system by trying to set up multiple concurrent readers. `input_stream.next()` sets up one reader looking for regular crossterm events while the `supports_keyboard_enhancement` query sets up another looking for internal events. The latter hangs for two seconds or until the former yields an event. By handling signals first we don't lock up the mutex by trying to read keyboard events.
* Ignore key-release keyboard events (#6139)Michael Davis2023-03-01
| | | | | Since crossterm 0.26.x, we receive press/release keyboard events on Windows always. We can ignore the release events though to emulate the behavior of keyboard input on Windows on crossterm 0.25.x.

* enable rendering in integration tests (#5819)Skyler Hawthorne2023-02-04
| | | | | | | | | This will allow testing more of the code base, as well as enable UI- specific testing. Debug mode builds are prohibitively slow for the tests, mostly because of the concurrency write tests. So there is now a profile for integration tests that sets the optimization level to 2 for a few helix crates, and lowers the number of rounds of concurrent writes to 1000.
* rework positioning/rendering and enable softwrap/virtual text (#5420)Pascal Kuthe2023-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * rework positioning/rendering, enables softwrap/virtual text This commit is a large rework of the core text positioning and rendering code in helix to remove the assumption that on-screen columns/lines correspond to text columns/lines. A generic `DocFormatter` is introduced that positions graphemes on and is used both for rendering and for movements/scrolling. Both virtual text support (inline, grapheme overlay and multi-line) and a capable softwrap implementation is included. fix picker highlight cleanup doc formatter, use word bondaries for wrapping make visual vertical movement a seperate commnad estimate line gutter width to improve performance cache cursor position cleanup and optimize doc formatter cleanup documentation fix typos Co-authored-by: Daniel Hines <d4hines@gmail.com> update documentation fix panic in last_visual_line funciton improve soft-wrap documentation add extend_visual_line_up/down commands fix non-visual vertical movement streamline virtual text highlighting, add softwrap indicator fix cursor position if softwrap is disabled improve documentation of text_annotations module avoid crashes if view anchor is out of bounds fix: consider horizontal offset when traslation char_idx -> vpos improve default configuration fix: mixed up horizontal and vertical offset reset view position after config reload apply suggestions from review disabled softwrap for very small screens to avoid endless spin fix wrap_indicator setting fix bar cursor disappearring on the EOF character add keybinding for linewise vertical movement fix: inconsistent gutter highlights improve virtual text API make scope idx lookup more ergonomic allow overlapping overlays correctly track char_pos for virtual text adjust configuration deprecate old position fucntions fix infinite loop in highlight lookup fix gutter style fix formatting document max-line-width interaction with softwrap change wrap-indicator example to use empty string fix: rare panic when view is in invalid state (bis) * Apply suggestions from code review Co-authored-by: Michael Davis <mcarsondavis@gmail.com> * improve documentation for positoning functions * simplify tests * fix documentation of Grapheme::width * Apply suggestions from code review Co-authored-by: Michael Davis <mcarsondavis@gmail.com> * add explicit drop invocation * Add explicit MoveFn type alias * add docuntation to Editor::cursor_cache * fix a few typos * explain use of allow(deprecated) * make gj and gk extend in select mode * remove unneded debug and TODO * mark tab_width_at #[inline] * add fast-path to move_vertically_visual in case softwrap is disabled * rename first_line to first_visual_line * simplify duplicate if/else --------- Co-authored-by: Michael Davis <mcarsondavis@gmail.com>

* Handle language server termination (#4797)Michael Davis2022-11-19
| | | | | | | | | | | | | This change handles a language server exiting. This was a UX sore-spot: if a language server crashed, Helix did not recognize the exit and continued to send requests to it. All requests would timeout since they would not receive responses. This would also hold-up Helix closing itself down since it would try to gracefully shutdown the server which is implemented in the LSP spec as a request. We could attempt to automatically restart the language server on crash. I left this for future work since that change will need to be slightly complicated: it will need to cover the case of a language server repeatedly crashing.

* fix(write): do not set new path on document until write succeedsSkyler Hawthorne2022-10-19
| | | | | | If a document is written with a new path, currently, in the event that the write fails, the document still gets its path changed. This fixes it so that the path is not updated unless the write succeeds.
* fix: buffer-close ensuring writesSkyler Hawthorne2022-10-19
| | | | Make sure buffer-close waits for the document to finish its writes.
* chore(write): serialize write operations within a DocumentSkyler Hawthorne2022-10-19
| | | | | | | | | | | | | | | The way that document writes are handled are by submitting them to the async job pool, which are all executed opportunistically out of order. It was discovered that this can lead to write inconsistencies when there are multiple writes to the same file in quick succession. This seeks to fix this problem by removing document writes from the general pool of jobs and into its own specialized event. Now when a user submits a write with one of the write commands, a request is simply queued up in a new mpsc channel that each Document makes to handle its own writes. This way, if multiple writes are submitted on the same document, they are executed in order, while still allowing concurrent writes for different documents.

* Exit gracefully when close operation fails (#4081)Skyler Hawthorne2022-10-03
| | | | | | | | If the close method fails, the editor will quit before restoring the terminal. This causes the shell to break if, e.g. the LS times out shutting down. This fixes this by always restoring the terminal after closing, and printing out a message to stderr if there is an error.

* Remove the .txt suffix from tutorBlaž Hrastnik2022-09-11
| | | | | | | | | | | | The tutor file is loaded as .txt which can potentially spawn a language server. Then the path is unset, but the LS remains active. This can cause panics since updates are now submitted for a doc with no path. As a quick workaround we remove the extension which should avoid detection. Fixes #3730

* Share the restore_term code between panic and normal exits (#3612)Charlie Groves2022-08-31
| | | | | | | | It was starting to diverge as the normal exit code was restoring the prompt but the panic code wasn't, and the panic code was disabling bracketed paste but the normal code wasn't. This changes the panic path slightly in that we won't disable raw mode if exiting alternate screen and disabling bracketed paste fails. If that happens, things are so busted I don't think it matters anyway.
