* 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>

* 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.

If case any of the two fails to be found, provide the user with messages to inform them of the issue and gracefully return. Closes: #5625 Signed-off-by: Filip Dutescu <filip.dutescu@gmail.com>
* 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.

* 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.

| | | | | | | Commit 1b89d3e5350f83b2ffb86a86326bd2714308ee53 introduced a regression where opening a new file would no longer work, because attempting to canonicalize its path would lead to a "No such file or directory" error. Fall back to opening a new file when encountering an error to fix this case.

* workspace symbols: Default to empty Vec on NoneMichael Davis2022-12-15
| | | | | | | A language server might send None as the response to workspace symbols. We should treat this as the empty Vec rather than the server sending an error status. This fixes the interaction with gopls which uses None to mean no matching symbols.
* Re-request workspace symbols on keypress in pickerGokul Soumya2022-12-15
| | | | | | | | | | | Most language servers limit the number of workspace symbols that are returned with an empty query even though all symbols are supposed to be returned, according to the spec (for perfomance reasons). This patch adds a workspace symbol picker based on a dynamic picker that allows re-requesting the symbols on every keypress (i.e. when the picker query text changes). The old behavior has been completely replaced, and I have only tested with rust-analyzer so far.
* Improve error message handling for theme loading failures (#5073)Michael Davis2022-12-15
| | | | | | | | | | | | | | | | | The error messages for a theme that failed to be deserialized (or otherwise failed to load) were covered up by the context/with_context calls: * The log message for a bad theme configured in config.toml would only say "Failed to deserilaize theme" * Selecting a bad theme via :theme would show "Theme does not exist" With these changes, we let the TOML deserializer errors bubble up, so the error messages can now say the line number of a duplicated key - and that key's name - when a theme fails to load because of a duplicated key. Providing a theme which does not exist to :theme still gives a helpful error message: "No such file or directory."

| | | | | | View::apply should only be called by EditorView after 42e37a571e75aaf4feb1717dfebe8cf215e535dd. This change removes the duplicate calls within undo/redo which could cause a panic.
* lsp: Check server provider capabilities (#3554)Michael Davis2022-11-22
| | | | | | | | | | | | | | Language Servers may signal that they do not support a method in the initialization result (server capabilities). We can check these when making LSP requests and hint in the status line when a method is not supported by the server. This can also prevent crashes in servers which assume that clients do not send requests for methods which are disabled in the server capabilities. There is an existing pattern the LSP client module where a method returns `Option<impl Future<Output = Result<_>>>` with `None` signaling no support in the server. This change extends this pattern to the rest of the client functions. And we log an error to the statusline for manually triggered LSP calls which return `None`.

* Capture word parts while calculating shellwords (#4632)Michael Davis2022-11-17
| | | | | | | | | | | | | | | | | | | This fixes an edge case for completing shellwords. With a file "a b.txt" in the current directory, the sequence `:open a\<tab>` will result in the prompt containing `:open aa\ b.txt`. This is because the length of the input which is trimmed when replacing with completion is calculated on the part of the input which is parsed by shellwords and then escaped (in a separate operation), which is lossy. In this case it loses the trailing backslash. The fix provided here refactors shellwords to track both the _words_ (shellwords with quotes and escapes resolved) and the _parts_ (chunks of the input which turned into each word, with separating whitespace removed). When calculating how much of the input to delete when replacing with the completion item, we now use the length of the last part. This also allows us to eliminate the duplicate work done in the `ends_with_whitespace` check.

| | | | | | | * Add workspace command picker * Make command typable * Add optional argument to lsp-workspace-command
* Fix command-mode completion behavior when input is escapedMichael Davis2022-11-07
| | | | | | | If `a\ b.txt` were a local file, `:o a\ <tab>` would fill the prompt with `:o aa\ b.txt` because the replacement range was calculated using the shellwords-parsed part. Escaping the part before calculating its length fixes this edge-case.
* Escape filenames in command completionMichael Davis2022-11-07
| | | | | | This changes the completion items to be rendered with shellword escaping, so a file `a b.txt` is rendered as `a\ b.txt` which matches how it should be inputted.
* Fix whitespace handling in command-mode completionMichael Davis2022-11-07
| | | | | | | | | | 8584b38cfbe6ffe3e5d539ad953c413e44e90bfa switched to shellwords for completion in command-mode. This changes the conditions for choosing whether to complete the command or use the command's completer. This change processes the input as shellwords up-front and uses shellword logic about whitespace to determine whether the command or argument should be completed.

| | | | | | | | | | | | | | | | Most commands that accept an argument show their current value if no argument is specified. The `:theme` command previously displayed an error message in the status bar if not provided with an argument: ``` Theme name not provided ``` It now shows the current theme name in the status bar if no argument is specified.
