* 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.
* tui: Allow toggling mouse capture at runtime (#6675)Michael Davis2023-04-21
| | | | | This picks up changes to the `editor.mouse` option at runtime - either through `:set-option` or `:config-reload`. When the value changes, we tell the terminal to enable or disable mouse capture sequences.

* Correctly reload theme on :config-reloadPascal Kuthe2023-03-31
| | | | | | The current implementation didn't reload the theme if no no theme was explicitly configured (so the default theme was used). This commit brings `refresh_theme` in line with the initialization code.

* 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>
* LSP: Send replies for malformed and unhandled RPC requests (#6058)Michael Davis2023-03-08
| | | | | | | | | | | | | | | | Previously we did not respond to malformed or unhandled LSP requests. The JSONRPC spec says that all non-notification requests must have responses: > When a rpc call is made, the Server MUST reply with a Response, > except for in the case of Notifications (Note that Helix is the "Server" in this case. Also from the spec: "The Server is defined as the origin of Response objects and the handler of Request objects.") So this change sends error replies for requests which can't be parsed or handled. Request IDs are also now added to the log messages for unhandled requests.
* Move terminal claim/restore code to helix-tuiMichael Davis2023-03-08
| | | | | | | | | | | | | | | | | | This moves the `Application::claim_term` and `helix-term::application::restore_term` functions into the helix-tui crate. How the terminal should be claimed and restored is a TUI concern and is implemented differently through different TUI backends. This cleans out a lot of crossterm and TUI code in Application and makes it easier to modify claim/restore based on information we query from the terminal host. The child commit will take advantage of this to cache the check for whether the host terminal supports the keyboard enhancement protocol. Without this change, caching that information takes much more code which is not easily reusable for anything else. The code to restore the terminal is somewhat duplicated by this patch: we want to restore the terminal in cases of panics. Panic handler hooks must live for `'static` and the Application's terminal does not.
* fix: Handle signals before crossterm events (#6170)Alexander Brevig2023-03-05
| | | | | | | | | | | This is a workaround for a freeze when suspending Helix with C-z on non-Windows systems. The check for the keyboard enhancement protocol locks up crossterm's internal event reading/polling system by trying to set up multiple concurrent readers. `input_stream.next()` sets up one reader looking for regular crossterm events while the `supports_keyboard_enhancement` query sets up another looking for internal events. The latter hangs for two seconds or until the former yields an event. By handling signals first we don't lock up the mutex by trying to read keyboard events.
* Ignore key-release keyboard events (#6139)Michael Davis2023-03-01
| | | | | Since crossterm 0.26.x, we receive press/release keyboard events on Windows always. We can ignore the release events though to emulate the behavior of keyboard input on Windows on crossterm 0.25.x.

* enable rendering in integration tests (#5819)Skyler Hawthorne2023-02-04
| | | | | | | | | This will allow testing more of the code base, as well as enable UI- specific testing. Debug mode builds are prohibitively slow for the tests, mostly because of the concurrency write tests. So there is now a profile for integration tests that sets the optimization level to 2 for a few helix crates, and lowers the number of rounds of concurrent writes to 1000.
* rework positioning/rendering and enable softwrap/virtual text (#5420)Pascal Kuthe2023-01-31

A generic `DocFormatter` is introduced that positions graphemes on and is used both for rendering and for movements/scrolling. Both virtual text support (inline, grapheme overlay and multi-line) and a capable softwrap implementation is included. fix picker highlight cleanup doc formatter, use word bondaries for wrapping make visual vertical movement a seperate commnad estimate line gutter width to improve performance cache cursor position cleanup and optimize doc formatter cleanup documentation fix typos Co-authored-by: Daniel Hines <d4hines@gmail.com> update documentation fix panic in last_visual_line funciton improve soft-wrap documentation add extend_visual_line_up/down commands fix non-visual vertical movement streamline virtual text highlighting, add softwrap indicator fix cursor position if softwrap is disabled improve documentation of text_annotations module avoid crashes if view anchor is out of bounds fix: consider horizontal offset when traslation char_idx -> vpos improve default configuration fix: mixed up horizontal and vertical offset reset view position after config reload apply suggestions from review disabled softwrap for very small screens to avoid endless spin fix wrap_indicator setting fix bar cursor disappearring on the EOF character add keybinding for linewise vertical movement fix: inconsistent gutter highlights improve virtual text API make scope idx lookup more ergonomic allow overlapping overlays correctly track char_pos for virtual text adjust configuration deprecate old position fucntions fix infinite loop in highlight lookup fix gutter style fix formatting document max-line-width interaction with softwrap change wrap-indicator example to use empty string fix: rare panic when view is in invalid state (bis) * Apply suggestions from code review Co-authored-by: Michael Davis <mcarsondavis@gmail.com> * improve documentation for positoning functions * simplify tests * fix documentation of Grapheme::width * Apply suggestions from code review Co-authored-by: Michael Davis <mcarsondavis@gmail.com> * add explicit drop invocation * Add explicit MoveFn type alias * add docuntation to Editor::cursor_cache * fix a few typos * explain use of allow(deprecated) * make gj and gk extend in select mode * remove unneded debug and TODO * mark tab_width_at #[inline] * add fast-path to move_vertically_visual in case softwrap is disabled * rename first_line to first_visual_line * simplify duplicate if/else --------- Co-authored-by: Michael Davis <mcarsondavis@gmail.com>

* 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.
