* Reimplement clipboard commands in terms of special regsMichael Davis2023-07-31
| | | | | | | | | | Since the clipboard provider now lives on the Registers type, we want to eliminate it from the Editor. We can do that and clean up the commands that interact with the clipboard by calling regular yank, paste and replace impls on the clipboard special registers. Eventually the clipboard commands could be removed once macro keybinding is supported.
* Use refactored Registers typeMichael Davis2023-07-31
| | | | | | | This is an unfortunately noisy change: we need to update virtually all callsites that access the registers. For reads this means passing in the Editor and for writes this means handling potential failure when we can't write to a clipboard register.

* (Updated) Apply motion API refinements (#6078)Gabriel Hansson2023-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * _apply_motion generalization where possible API encourages users to not forget setting `editor.last_motion` when applying a motion. But also not setting `last_motion` without applying a motion first. * (rename) will_find_char -> find_char method name makes it sound like it would be returning a boolean. * use _apply_motion in find_char Feature that falls out from this is that repetitions of t,T,f,F are saved with the context extention/move and count. (Not defaulting to extend by 1 count). * Finalize apply_motion API last_motion is now a private field and can only be set by calling Editor.apply_motion(). Removing need (and possibility) of writing: `motion(editor); editor.last_motion = motion` Now it's just: `editor.apply_motion(motion)` * editor.last_message: rm Box wrap around Arc * Use pre-existing `Direction` rather than custom `SearchDirection`. * `LastMotion` type alias for `Option<Arc<dyn Fn(&mut Editor)>>` * Take motion rather than cloning it. Co-authored-by: Michael Davis <mcarsondavis@gmail.com> * last_motion as Option<Motion>. * Use `Box` over `Arc` for `last_motion`. --------- Co-authored-by: Michael Davis <mcarsondavis@gmail.com>

* Mark buffers created from stdin as modified (#7431)Michael Davis2023-06-26
| | | | | | | | | This resolves some confusing behavior where a scratch document created by piping into hx is discarded when navigating away from that document. We discard any scratch documents that are not modified and the original `Editor::new_file_from_stdin` would create unmodified documents. We refactor this function to create an empty document first and then to apply the text from stdin as a change.

* 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>

* treat replace/insertmode consistently, default to insertPascal Kuthe2023-03-10
|
* 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.
* 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>
