* LSP: Add request ID to request timeout message (#6010)Michael Davis2023-02-16
| | | | This improves error logging for requests - without the ID it's hard to know which request is the one that timed out.
* 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.

* feat(lsp): pass client_info on initialization (#4904)Matouš Dzivjak2022-12-09
| | | | Pass client name ('helix') and client version (version / git hash) to LSP server on initialization.
* 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`.
* lsp: Resolve completion item asynchronously on idle-timeout (#4781)Michael Davis2022-11-18
| | | | | | | | | | | | | | | | | | | | | d7d0d5ffb79b6f2e09c6ab8af6e112c41e6f73e8 resolves completion items on the idle-timeout event. The `Completion::resolve_completion_item` function blocks on the LSP request though, which blocks the compositor and in turn blocks the event loop. So until the language server returns the resolved completion item, Helix is unable to respond to keypresses or other LSP messages. This is typically ok since the resolution request is fast but for some language servers this can be problematic, and ideally we shouldn't be blocking like this anyways. When receiving a `completionItem/resolve` request, the Volar server sends a `workspace/configuration` request to Helix and blocks itself on the response, leading to a deadlock. Eventually the resolve request times out within Helix but Helix is locked up and unresponsive in that window. This change resolves the completion item without blocking the compositor.

* Split helix_core::find_root and helix_loader::find_local_config_dirs (#3929)Riccardo Binetti2022-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Split helix_core::find_root and helix_loader::find_local_config_dirs The documentation of find_root described the following priority for detecting a project root: - Top-most folder containing a root marker in current git repository - Git repository root if no marker detected - Top-most folder containing a root marker if not git repository detected - Current working directory as fallback The commit contained in https://github.com/helix-editor/helix/pull/1249 extracted and changed the implementation of find_root in find_root_impl, actually reversing its result order (since that is the order that made sense for the local configuration merge, from innermost to outermost ancestors). Since the two uses of find_root_impl have different requirements (and it's not a matter of reversing the order of results since, e.g., the top repository dir should be used by find_root only if there's not marker in other dirs), this PR splits the two implementations in two different specialized functions. In doing so, find_root_impl is removed and the implementation is moved back in find_root, moving it closer to the documented behaviour thus making it easier to verify it's actually correct * helix-core: remove Option from find_root return type It always returns some result, so Option is not needed

* embed jsonrpc types from jsonrpc-core crate (#2801)Michael Davis2022-06-18
| | | | | | | | | | | | | | We should not depend on jsonrpc-core anymore: * The project just announced it's no longer actively maintained[^1], preferring their new implementation in `jsonrpsee`. * The types are too strict: we would benefit from removing some `#[serde(deny_unknown_fields)]` annotations to allow language servers that disrespect the spec[^2]. * We don't use much of the project. Just the types out of core. These are easy to embed directly into the `helix-lsp` crate. [^1]: https://github.com/paritytech/jsonrpc/pull/674 [^2]: https://github.com/helix-editor/helix/issues/2786

* Send active diagnostics to LSP when requesting code actions. (#2005)Robin Jadoul2022-04-17
| | | | | | | | | | | * Send active diagnostics to LSP when requesting code actions. This allows for e.g. clangd to properly send the quickfix code actions corresponding to those diagnostics as options. The LSP spec v3.16.0 introduced an opaque `data` member that would allow the server to persist arbitrary data between the diagnostic and the code actions request, but this is not supported yet by this commit. * Reuse existing range_to_lsp_range functionality
