* 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.

* feat(debug): highlight current line (#5957)Filip Dutescu2023-03-29
| | | | | | | | | | | | | | | | | | Add new theme highlight keys, for setting the colour of the breakpoint character and the current line at which execution has been paused at. The two new keys are `ui.highlight.frameline` and `ui.debug.breakpoint`. Highlight according to those keys, both the line at which debugging is paused at and the breakpoint indicator. Add an indicator for the current line at which execution is paused at, themed by the `ui.debug.active` theme scope. Update various themes to showcase how the new functionality works. Better icons are dependent on #2869, and as such will be handled in the future, once it lands. Closes: #5952 Signed-off-by: Filip Dutescu <filip.dutescu@gmail.com>

* fix view anchors not at start of a visual linePascal Kuthe2023-03-27
| | | | | | | | | | | | | | | | | | | | | The top of a view is marked by a char idx anchor. That char idx is usually the first character of the visual line it's on. We use a char index instead of a line index because the view may start in the middle of a line with soft wrapping. However, it's possible to temporarily endup in a state where this anchor is not the first character of the first visual line. This is pretty rare because edits usually happen inside/after the view. In most cases we handle this case correctly. However, if the cursor is before the anchor (but still in view) there can be crashes or visual artifacts. This is caused by the fact that visual_offset_from_anchor (and the positioning code in view.rs) incorrectly assumed that the (cursor) position is always after the view anchor if the cursor is in view. But if the anchor is not the first character of the first visual line this is not the case anymore. In that case crashes and visual artifacts are possible. This commit fixes that problem by changing `visual_offset_from_anchor` (and callsites) to properly consider that case.

* 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>
* discard stale completion requestsPascal Kuthe2023-03-09
| | | | | | | | | | | | | | | | | Completion requests are computed asynchronously to avoid common micro freezes while editing. This means that once a completion request completes, the state of the editor might have changed. Currently, there is a check to ensure we are still in insert mode. However, we also need to ensure that the view and document hasn't changed to avoid accidentally using a savepoint with the wrong view/document. Furthermore, the editor might request a new completion while the previous completion request hasn't complemented yet. This can lead to weird flickering or an outdated completion request replacing a newer completion that has already completed (the LSP server is not required to process completion requests in order). This change also needed to ensure determinism/linear ordering so that completion popup always correspond to the last completion request.
* store multiple snapshots on the document at oncePascal Kuthe2023-03-09
| | | | | | | | | | | | | | | | | | Fixing autocomplete required moving the document savepoint before the asynchronous completion request. However, this in turn causes new bugs: If the completion popup is open, the savepoint is restored when the popup closes (or another entry is selected). However, at that point a new completion request might already have been created which would have replaced the new savepoint (therefore leading to incorrectly applied complies). This commit fixes that bug by allowing in arbitrary number of savepoints to be tracked on the document. The savepoints are reference counted and therefore remain valid as long as any reference to them remains. Weak reference are stored on the document and any reference that can not be upgraded anymore (hence no strong reference remain) are automatically discarded.
* save selection before completion savepointPascal Kuthe2023-03-09
| | | | | | | | | Currently, the selection is not saved/restored when completion checkpoints are applied. This is usually fine because undoing changes usually restores maps selections back in insert mode. But this is not always the case and especially problematic in the presence of multi-cursor completions (since completions are applied relative to the selection/cursor) and snippets (which can change the selection)
* Softwrapping improvements (#5893)Clément Delafargue2023-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * use max_line_width + 1 during softwrap to account for newline char Helix softwrap implementation always wraps lines so that the newline character doesn't get cut off so he line wraps one chars earlier then in other editors. This is necessary, because newline chars are always selecatble in helix and must never be hidden. However That means that `max_line_width` currently wraps one char earlier than expected. The typical definition of line width does not include the newline character and other helix commands like `:reflow` also don't count the newline character here. This commit makes softwrap use `max_line_width + 1` instead of `max_line_width` to correct the impedance missmatch. * fix typos Co-authored-by: Jonathan Lebon <jonathan@jlebon.com> * Add text-width to config.toml * text-width: update setting documentation * rename leftover config item * remove leftover max-line-length occurrences * Make `text-width` optional in editor config When it was only used for `:reflow` it made sense to have a default value set to `80`, but now that soft-wrapping uses this setting, keeping a default set to `80` would make soft-wrapping behave more aggressively. * Allow softwrapping to ignore `text-width` Softwrapping wraps by default to the viewport width or a configured `text-width` (whichever's smaller). In some cases we only want to set `text-width` to use for hard-wrapping and let longer lines flow if they have enough space. This setting allows that. * Revert "Make `text-width` optional in editor config" This reverts commit b247d526d69adf41434b6fd9c4983369c785aa22. * soft-wrap: allow per-language overrides * Update book/src/configuration.md Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> * Update book/src/languages.md Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> * Update book/src/configuration.md Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> --------- Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> Co-authored-by: Jonathan Lebon <jonathan@jlebon.com> Co-authored-by: Alex Boehm <alexb@ozrunways.com> Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>

* Fix scrolloff at view bottom (#6142)Pascal Kuthe2023-03-03
| | | | | | | Fixes a regression introduced in #5420 where a scrolloff of `x - 1` was used instead if `x` at the bottom of the screen. This was especially problematic if the scrolloff was set to `0` in that case the scrolloff behaved as tough set to `-1` and the cursor disappeared from the view if scrolled to the botoom.
* feat(dap): send Disconnect if Terminated event received (#5532)Filip Dutescu2023-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | Send a `Disconnect` DAP request if the `Terminated` event is received. According to the specification, if the debugging session was started by as `launch`, the debuggee should be terminated alongside the session. If instead the session was started as `attach`, it should not be disposed of. This default behaviour can be overriden if the `supportTerminateDebuggee` capability is supported by the adapter, through the `Disconnect` request `terminateDebuggee` argument, as described in [the specification][discon-spec]. This also implies saving the starting command for a debug sessions, in order to decide which behaviour should be used, as well as validating the capabilities of the adapter, in order to decide what the disconnect should do. An additional change made is handling of the `Exited` event, showing a message if the exit code is different than `0`, for the user to be aware off the termination failure.
