* fix snippet bugs and multicursor completion edgecasesPascal Kuthe2023-03-10
| | | | | | | | | | | | | | | | Multicursor completions may overlap and therefore overlapping completions must be dropped to avoid crashes. Furthermore, multicursor edits might simply be out of range if the word before/after the cursor is shorter. This currently leads to crashes, instead these selections are now also removed for completions. This commit also significantly refactors snippet transaction generation so that tabstops behave correctly with the above rules. Furthermore, snippet tabstops need to be carefully mapped to ensure their position is correct and consistent with our selection semantics. Finally, we now keep a partially updated Rope while creating snippet transactions so that we can fill information into snippets that depends on the position in the document.

* 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.

* 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.
* 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.

* Apply completion edits to all cursors (#4496)Michael Davis2022-12-06
| | | | | | | | Completion edits - either basic `insert_text` strings or structured `text_edit`s - are assumed by the LSP spec to apply to the current cursor (or at least the trigger point). We can use the range (if any) and text given by the Language Server to create a transaction that changes all ranges in the current selection though, allowing auto- complete to affect multiple cursors.

* 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.

* 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

* Don't panic on LSP parsing errorsBlaž Hrastnik2022-05-11
| | | | | | This made sense initially when the implementation was still new (so we got user reports more frequently), but a parsing error now generally signifies a language server isn't properly implementing the spec.

* prevent panic when receiving malformed LSP PublishDiagnostic (#2160)Michael Davis2022-04-18
| | | | | | | | | | | Instead of panicing we can discard the malformed diagnostic. This `.parse()` fails commonly when a non-conformant language server gives a diagnostic with a location that breaks the spec: { "character": 0, "line": -1 } can currently be returned by ElixirLS and the python LS. Other messages in this block are discarded but this one feels special enough to log.
* 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
