* Improve error handling for `which::which` failuresMichael Davis2024-01-24

* 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).
* feat(lsp): implement show document request (#8865)Matouš Dzivjak2024-01-17
| | | | | | | | | | | | | | | | | | | | | | * feat(lsp): implement show document request Implement [window.showDocument](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#window_showDocument) LSP server-sent request. This PR builds on top of helix-editor#5820, moves the external-URL opening functionality into shared crate-level function that returns a callback that is now used by both the `open_file` command as well as the window.showDocument handler if the URL is marked as external. * add return * use vertical split * refactor --------- Co-authored-by: Michael Davis <mcarsondavis@gmail.com>

* LSP: Forcefully shutdown uninitialized servers (#7449)Michael Davis2023-06-29
| | | | | | | | | | | | | | | | | | The LSP spec has this to say about initialize: > Until the server has responded to the `initialize` request with an > `InitializeResult`, the client must not send any additional requests > or notifications to the server. (https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initialize) The spec is not really explicit about how to handle this scenario. Before a client sends the 'initialize' request we are allowed to send an 'exit' notification, but after 'initialize' we can't send any requests (like shutdown) or notifications (like exit). So my intepretation is that we should forcefully close the server in this state. This matches the behavior of Neovim's built-in LSP client: https://github.com/neovim/neovim/blob/5ceb2238d3685255cd517ca87fd7edae9ed88811/runtime/lua/vim/lsp.lua#L1610-L1628

* 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.

* revamped snippet text element parsingPascal Kuthe2023-03-16
| | | | | | | | | | | | | | Snippet text elements can contain escape sequences that must be treated properly. Furthermore snippets must always escape certain characters (like `}` or `\`). The function has been updated to account for that. `text` is now also included with `anything` to match the grammar and can also match empty text. To avoid infinite loops the `non-empty` combinator has been added which is automatically used in the `one_or_more` and `zero_or more` combinator where the problemn would occur.
