* Move terminal claim/restore code to helix-tuiMichael Davis2023-03-08
| | | | | | | | | | | | | | | | | | This moves the `Application::claim_term` and `helix-term::application::restore_term` functions into the helix-tui crate. How the terminal should be claimed and restored is a TUI concern and is implemented differently through different TUI backends. This cleans out a lot of crossterm and TUI code in Application and makes it easier to modify claim/restore based on information we query from the terminal host. The child commit will take advantage of this to cache the check for whether the host terminal supports the keyboard enhancement protocol. Without this change, caching that information takes much more code which is not easily reusable for anything else. The code to restore the terminal is somewhat duplicated by this patch: we want to restore the terminal in cases of panics. Panic handler hooks must live for `'static` and the Application's terminal does not.

* Render every LSP snippets for every cursorAndrii Grynenko2023-03-08
| | | | | | | This refactors the snippet logic to be largely unaware of the rest of the document. The completion application logic is moved into generate_transaction_from_snippet which is extended to support dynamically computing replacement text.
* Delete snippet placeholders when accepting completionPascal Kuthe2023-03-08
| | | | | | | When accepting a snippet completion we automatically delete the placeholders for now as doing so manual is quite cumbersome. In the future we should keep these as a mark + virtual text that is automatically removed once the cursor moves there.

* feat(dap): implement Restart request (#5651)Filip Dutescu2023-03-06
| | | | | | | | | | | | | | | Add a restart debug session command, which would issue a [Restart Request][1], if the debugger supports it and a session is running. It uses the same arguments and requests used to start the initial session, when recreating it. It builds upon #5532, making use of the changes to the termination workflow of a session.

* 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.
* Add shift-backspace keybind alias for backspace (#4937)lesleyrs2023-02-28
| | | | | | | | | | | When the Kitty Keyboard Protocol is enabled, S-backspace is distinguished from backspace with no modifiers. This is awkward when typing because it's very easy to accidentally hold shift and press backspace temporarily when typing capital letters. Kakoune (which is also a Kitty Keyboard Protocol application) treats S-backspace as backspace too: https://github.com/mawww/kakoune/blob/3150e9b3cd8e61d9bc68245d67822614d4376cf4/src/input_handler.cc#L1275

* feat(dap): send Disconnect if Terminated event received (#5532)Filip Dutescu2023-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | Send a `Disconnect` DAP request if the `Terminated` event is received. According to the specification, if the debugging session was started by as `launch`, the debuggee should be terminated alongside the session. If instead the session was started as `attach`, it should not be disposed of. This default behaviour can be overriden if the `supportTerminateDebuggee` capability is supported by the adapter, through the `Disconnect` request `terminateDebuggee` argument, as described in [the specification][discon-spec]. This also implies saving the starting command for a debug sessions, in order to decide which behaviour should be used, as well as validating the capabilities of the adapter, in order to decide what the disconnect should do. An additional change made is handling of the `Exited` event, showing a message if the exit code is different than `0`, for the user to be aware off the termination failure.

* feat(ui): deprecated completions (#5932)Matouš Dzivjak2023-02-13
| | | | | | | | | | | | | | | | | | * feat(ui): deprecated completions Mark deprecated completions using strike-through (CROSSED_OUT modifier). The deprection information is taken either from the `deprecated` field of the completion item or from the completion tags. The field seems to be the older way of passing the deprecated information and it was already marked as deprecated for Symbol. In completion item the field is still valid but it seems that the LSP is moving in the general direction of using tags for this kind of information and as such relying on tags as well seems reasonable and future-proof.

* Negotiate LSP Position Encoding (#5894)Pascal Kuthe2023-02-11
| | | | | | | So far LSP always required that `PositionEncoding.characters` is an UTF-16 offset. Now that LSP 3.17 is available in `lsp-types` request the server to send char offsets (UTF-32) or byte offsets (UTF-8) instead. For compatability with old servers, UTF-16 remains as the fallback as required by the standard.
* Make `m` textobject look for pairs enclosing selections (#3344)Daniel S Poulin2023-02-10

This ensures that the pair found encloses each selection, which is likely to be intuitively what is expected of this textobject. * Simplification of match code Co-authored-by: Michael Davis <mcarsondavis@gmail.com> * Adjust logic for ensuring surround range encloses selection Prior, it was missing the case where the start of the selection came before the opening brace.

* Select change range for goto_first/last_change commands (#5206)Michael Davis2023-02-07
| | | | | | This matches the behavior from 42ad1a9e043e2e0fb148924ff79b9abbe06907ae but for the first and last change. The selection rules are the same as for goto_next/prev_change: additions and modifications select the added and modified range while deletions are represented with a point.
* 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.
