* correctly store snapshots when repeating insert-mode actionsPascal Kuthe2023-03-09
| | | | | | | | | | | | Repeating completions currently crates a savepoint when a completion popup was triggered (so after the request completed). Just like for normal completions the savepoint must be created at the request. The occurrence of the completion request was previously not saved in `last_insert`. To that end a new `InsertEvent::RequestCompletion` variant has been added. When replayed this event creates a snapshot that is "actived" by the `TriggerCompletion` event and subsequently used during any `InsertEvent::CompletiuonApply` events.
* discard stale completion requestsPascal Kuthe2023-03-09
| | | | | | | | | | | | | | | | | Completion requests are computed asynchronously to avoid common micro freezes while editing. This means that once a completion request completes, the state of the editor might have changed. Currently, there is a check to ensure we are still in insert mode. However, we also need to ensure that the view and document hasn't changed to avoid accidentally using a savepoint with the wrong view/document. Furthermore, the editor might request a new completion while the previous completion request hasn't complemented yet. This can lead to weird flickering or an outdated completion request replacing a newer completion that has already completed (the LSP server is not required to process completion requests in order). This change also needed to ensure determinism/linear ordering so that completion popup always correspond to the last completion request.
* store multiple snapshots on the document at oncePascal Kuthe2023-03-09
| | | | | | | | | | | | | | | | | | Fixing autocomplete required moving the document savepoint before the asynchronous completion request. However, this in turn causes new bugs: If the completion popup is open, the savepoint is restored when the popup closes (or another entry is selected). However, at that point a new completion request might already have been created which would have replaced the new savepoint (therefore leading to incorrectly applied complies). This commit fixes that bug by allowing in arbitrary number of savepoints to be tracked on the document. The savepoints are reference counted and therefore remain valid as long as any reference to them remains. Weak reference are stored on the document and any reference that can not be upgraded anymore (hence no strong reference remain) are automatically discarded.
* save selection before completion savepointPascal Kuthe2023-03-09
| | | | | | | | | Currently, the selection is not saved/restored when completion checkpoints are applied. This is usually fine because undoing changes usually restores maps selections back in insert mode. But this is not always the case and especially problematic in the presence of multi-cursor completions (since completions are applied relative to the selection/cursor) and snippets (which can change the selection)

* LSP: Support textDocument/prepareRename (#6103)Kyle Smith2023-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * LSP: Support textDocument/prepareRename 'textDocument/prepareRename' can be used by the client to ask the server the range of the symbol under the cursor which would be changed by a subsequent call to 'textDocument/rename' with that position. We can use this information to fill the prompt with an accurate prefill which can improve the UX for renaming symbols when the symbol doesn't align with the "word" textobject. (We currently use the "word" textobject as a default value for the prompt.)

* Softwrapping improvements (#5893)Clément Delafargue2023-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * use max_line_width + 1 during softwrap to account for newline char Helix softwrap implementation always wraps lines so that the newline character doesn't get cut off so he line wraps one chars earlier then in other editors. This is necessary, because newline chars are always selecatble in helix and must never be hidden. However That means that `max_line_width` currently wraps one char earlier than expected. The typical definition of line width does not include the newline character and other helix commands like `:reflow` also don't count the newline character here. This commit makes softwrap use `max_line_width + 1` instead of `max_line_width` to correct the impedance missmatch. * fix typos Co-authored-by: Jonathan Lebon <jonathan@jlebon.com> * Add text-width to config.toml * text-width: update setting documentation * rename leftover config item * remove leftover max-line-length occurrences * Make `text-width` optional in editor config When it was only used for `:reflow` it made sense to have a default value set to `80`, but now that soft-wrapping uses this setting, keeping a default set to `80` would make soft-wrapping behave more aggressively. * Allow softwrapping to ignore `text-width` Softwrapping wraps by default to the viewport width or a configured `text-width` (whichever's smaller). In some cases we only want to set `text-width` to use for hard-wrapping and let longer lines flow if they have enough space. This setting allows that. * Revert "Make `text-width` optional in editor config" This reverts commit b247d526d69adf41434b6fd9c4983369c785aa22. * soft-wrap: allow per-language overrides * Update book/src/configuration.md Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> * Update book/src/languages.md Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> * Update book/src/configuration.md Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> --------- Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> Co-authored-by: Jonathan Lebon <jonathan@jlebon.com> Co-authored-by: Alex Boehm <alexb@ozrunways.com> Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>

* DynamicPicker: Recalculate column widths for new options (#6004)Michael Davis2023-03-08
| | | | | | | | | | | | | | This fixes blank row text in a DynamicPicker which is initially given no options. This can happen for language servers which respond to the workspace symbol request for an empty query with an empty list of symbols, and that behavior is somewhat common since returning all symbols as the spec suggests is very expensive. For empty options, `Picker::new` calculated the widths of each column as 0. We can recalculate the column widths when the new options are set to fix this. This refactor is also a good opportunity to formalize setting new options on a picker: besides setting the new options and calculating column widths we also want to reset the cursor and rescore the options.
* Jump to symbol ranges in LSP goto commands (#5986)Michael Davis2023-03-08

* LSP: Send replies for malformed and unhandled RPC requests (#6058)Michael Davis2023-03-08
| | | | | | | | | | | | | | | | Previously we did not respond to malformed or unhandled LSP requests. The JSONRPC spec says that all non-notification requests must have responses: > When a rpc call is made, the Server MUST reply with a Response, > except for in the case of Notifications (Note that Helix is the "Server" in this case. Also from the spec: "The Server is defined as the origin of Response objects and the handler of Request objects.") So this change sends error replies for requests which can't be parsed or handled. Request IDs are also now added to the log messages for unhandled requests.
* 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.

* 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.

* 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.

* 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.

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.

For compatability with old servers, UTF-16 remains as the fallback as required by the standard.
