* Support LSP diagnostic tags (#9780)Michael Davis2024-03-02

* Use a hook for resolving completion itemsMichael Davis2024-02-23
| | | | | | Previously we used the IdleTimeout event to trigger LSP `completion/resolveItem` requests. We can now refactor this to use an event system hook instead and lower the timeout.
* Add required-root-patterns for situational lsp activation (#8696)ontley2024-02-12
| | | | | | | | | | | | | | | | | | | * Added required-root-patterns for situational lsp activation using globbing * Replaced filter_map with flatten * updated book to include required-root-patterns option * fixed wrong function name for path * Added globset to helix-core. Moved globset building to config parsing. * Normalize implements AsRef * cargo fmt * Revert "cargo fmt" This reverts commit ca8ce123e8d77d2ae8ed84d5273a9b554101b0db.
* make path changes LSP spec conform (#8949)Pascal Kuthe2024-01-28
| | | | | | | | | | | | | | | | | Currently, helix implements operations which change the paths of files incorrectly and inconsistently. This PR ensures that we do the following whenever a buffer is renamed (`:move` and workspace edits) * always send did_open/did_close notifications * send will_rename/did_rename requests correctly * send them to all LSP servers not just those that are active for a buffer * also send these requests for paths that are not yet open in a buffer (if triggered from workspace edit). * only send these if the server registered interests in the path * autodetect language, indent, line ending, .. This PR also centralizes the infrastructure for path setting and therefore `:w <path>` benefits from similar fixed (but without didRename)

* Re-export `which` from `helix-stdx::env`Michael Davis2024-01-24
| | | | | | | | | | We use `which::which` in many crates, so `which` was a separate dependency across all of them. We can centralize `which` into the stdx crate so it's easy for all crates to depend on it. I also moved the rest of `helix-view/src/env.rs` into helix-stdx's `env` module since it only contained a thin wrapper around `which` and `std::env`.

* Create helix-stdx crate for stdlib extensionsMichael Davis2024-01-18
| | | | | | | | | | | | | helix-stdx is meant to carry extensions to the stdlib or low-level dependencies that are useful in all other crates. This commit starts with all of the path functions from helix-core and the CWD tracking that lived in helix-loader. The CWD tracking in helix-loader was previously unable to call the canonicalization functions in helix-core. Switching to our custom canonicalization code should make no noticeable difference though since `std::env::current_dir` returns a canonicalized path with symlinks resolved (at least on unix).

* Adds support for multiple language servers per language.Philipp Mildenberger2023-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Language Servers are now configured in a separate table in `languages.toml`: ```toml [langauge-server.mylang-lsp] command = "mylang-lsp" args = ["--stdio"] config = { provideFormatter = true } [language-server.efm-lsp-prettier] command = "efm-langserver" [language-server.efm-lsp-prettier.config] documentFormatting = true languages = { typescript = [ { formatCommand ="prettier --stdin-filepath ${INPUT}", formatStdin = true } ] } ``` The language server for a language is configured like this (`typescript-language-server` is configured by default): ```toml [[language]] name = "typescript" language-servers = [ { name = "efm-lsp-prettier", only-features = [ "format" ] }, "typescript-language-server" ] ``` or equivalent: ```toml [[language]] name = "typescript" language-servers = [ { name = "typescript-language-server", except-features = [ "format" ] }, "efm-lsp-prettier" ] ``` Each requested LSP feature is priorized in the order of the `language-servers` array. For example the first `goto-definition` supported language server (in this case `typescript-language-server`) will be taken for the relevant LSP request (command `goto_definition`). If no `except-features` or `only-features` is given all features for the language server are enabled, as long as the language server supports these. If it doesn't the next language server which supports the feature is tried. The list of supported features are: - `format` - `goto-definition` - `goto-declaration` - `goto-type-definition` - `goto-reference` - `goto-implementation` - `signature-help` - `hover` - `document-highlight` - `completion` - `code-action` - `workspace-command` - `document-symbols` - `workspace-symbols` - `diagnostics` - `rename-symbol` - `inlay-hints` Another side-effect/difference that comes with this PR, is that only one language server instance is started if different languages use the same language server.

* Prefer utf-8 over utf-32Pascal Kuthe2023-03-31
| | | | | | | | Utf-8 support has been around for a while as an unstable feature but utf-32 is fairly new. A bunch of LS (like rust-analyzer) added this in a pinch, but it's pretty broken right now. The performance overhead is not very large (still a lot better than utf-16). We can switch back once the ecosystem has matured.

* 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.)

* LSP: Add request ID to request timeout message (#6010)Michael Davis2023-02-16

* 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

* 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
