* LSP: Key diagnostics off file path instead of URIMichael Davis2024-02-25
| | | | | | | | | URIs need to be normalized to be comparable. For example a language server could send a URI for a path containing '+' as '%2B' but we might encode this in something like 'Document::url' as just '+'. We can normalize the URI straight into a PathBuf though since this is the only value we compare these diagnostics URIs against. This also covers edge-cases like windows drive letter capitalization.
* fix lsp config reload (#9415)kyfanc2024-02-13
| | | | | | | | `syn_loader` was replaced rather than interior value being replace, old value was still being referenced and not updated after `:config-refresh`. By using `ArcSwap` like for `config`, each `.load()` call will return the most updated value. Co-authored-by: kyfan <kyfan@email>
* Add glob file type support (#8006)Galen Abell2024-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Replace FileType::Suffix with FileType::Glob Suffix is rather limited and cannot be used to match files which have semantic meaning based on location + file type (for example, Github Action workflow files). This patch adds support for a Glob FileType to replace Suffix, which encompasses the existing behavior & adds additional file matching functionality. Globs are standard Unix-style path globs, which are matched against the absolute path of the file. If the configured glob for a language is a relative glob (that is, it isn't an absolute path or already starts with a glob pattern), a glob pattern will be prepended to allow matching relative paths from any directory. The order of file type matching is also updated to first match on globs and then on extension. This is necessary as most cases where glob-matching is useful will have already been matched by an extension if glob matching is done last. * Convert file-types suffixes to globs * Use globs for filename matching Trying to match the file-type raw strings against both filename and extension leads to files with the same name as the extension having the incorrect syntax. * Match dockerfiles with suffixes It's common practice to add a suffix to dockerfiles based on their context, e.g. `Dockerfile.dev`, `Dockerfile.prod`, etc. * Make env filetype matching more generic Match on `.env` or any `.env.*` files. * Update docs * Use GlobSet to match all file type globs at once * Update todo.txt glob patterns * Consolidate language Configuration and Loader creation This is a refactor that improves the error handling for creating the `helix_core::syntax::Loader` from the default and user language configuration. * Fix integration tests * Add additional starlark file-type glob --------- Co-authored-by: Michael Davis <mcarsondavis@gmail.com>
* 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)

* 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).

* make diagnostics stick to word boundariesPascal Kuthe2023-12-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Diagnostics are currently extended if text is inserted at their end. This is desirable when inserting text after an identifier. For example consider: let foo = 2; --- unused variable Renaming the identifier should extend the diagnostic: let foobar = 2; ------ unused variable This is currently implemented in helix but as a consequence adding whitespaces or a type hint also extends the diagnostic: let foo = 2; -------- unused variable let foo: Bar = 2; -------- unused variable In these cases the diagnostic should remain unchanged: let foo = 2; --- unused variable let foo: Bar = 2; --- unused variable As a heuristic helix will now only extend diagnostics that end on a word char if new chars are appended to the word (so not for punctuation/ whitespace). The idea for this mapping was inspired for the word level tracking vscode uses for many positions. While VSCode doesn't currently update diagnostics after receiving publishDiagnostic it does use this system for inlay hints for example. Similarly, the new association mechanism implemented here can be used for word level tracking of inlay hints. A similar mapping function is implemented for word starts. Together these can be used to make a diagnostic stick to a word. If that word is removed that diagnostic is automatically removed too. This is the exact same behavior VSCode inlay hints eixibit.

* LSP: Discard publishDiagnostic from uninitialized servers (#7467)Michael Davis2023-06-28
| | | | | | | | | | | | | | The spec explicitly disallows publishDiagnostic to be sent before the initialize response: > ... the server is not allowed to send any requests or notifications to > the client until it has responded with an InitializeResult ... (https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initialize) But if a non-compliant server sends this we currently panic because we '.expect()' the server capabilities to be known to fetch the position encoding. Instead of panicking we can discard the notification and log the non-compliant behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* helix-term: send the STOP signal to all processes in the process group (#3546)Cole Helbling2023-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * helix-term: send the STOP signal to all processes in the process group From kill(3p): If pid is 0, sig shall be sent to all processes (excluding an unspecified set of system processes) whose process group ID is equal to the process group ID of the sender, and for which the process has permission to send a signal. This fixes the issue of running `git commit`, attempting to suspend helix with ^Z, and then not regaining control over the terminal and having to press ^Z again. * helix-term: use libc directly to send STOP signal * helix-term: document safety of libc::kill * helix-term: properly handle libc::kill's failure I misread the manpage for POSIX `kill` -- it returns `-1` in the failure case, and sets `errno`, which is retrieved via `std::io::Error::last_os_error()`, has its string representation printed out, and then exits with the matching status code (or 1 if, for whatever reason, there is no matching status code). * helix-term: expand upon why we need to SIGSTOP the entire process group Also add a link back to one of the upstream issues.

* Generalised to multiple runtime directories with priorities (#5411)paul-scott2023-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Generalised to multiple runtime directories with priorities This is an implementation for #3346. Previously, one of the following runtime directories were used: 1. `$HELIX_RUNTIME` 2. sibling directory to `$CARGO_MANIFEST_DIR` 3. subdirectory of user config directory 4. subdirectory of path to helix executable The first directory provided / found to exist in this order was used as a root for all runtime file searches (grammars, themes, queries). This change lowers the priority of `$HELIX_RUNTIME` so that the user config runtime has higher priority. More significantly, all of these directories are now searched for runtime files, enabling a user to override default or system-level runtime files. If the same file name appears in multiple runtime directories, the following priority is now used: 1. sibling directory to `$CARGO_MANIFEST_DIR` 2. subdirectory of user config directory 3. `$HELIX_RUNTIME` 4. subdirectory of path to helix executable One exception to this rule is that a user can have a `themes` directory directly in the user config directory that has higher piority to `themes` directories in runtime directories. That behaviour has been preserved. As part of implementing this feature `theme::Loader` was simplified and the cycle detection logic of the theme inheritance was improved to cover more cases and to be more explicit. * Removed AsRef usage to avoid binary growth * Health displaying ;-separated runtime dirs * Changed HELIX_RUNTIME build from src instructions * Updated doc for more detail on runtime directories * Improved health symlink printing and theme cycle errors The health display of runtime symlinks now prints both ends of the link. Separate errors are given when theme file is not found and when the only theme file found would form an inheritence cycle. * Satisfied clippy on passing Path * Clarified highest priority runtime directory purpose * Further clarified multiple runtime details in book Also gave markdown headings to subsections. Fixed a error with table indentation not building table that also appears present on master. --------- Co-authored-by: Paul Scott <paul.scott@anu.edu.au> Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>
