* Prefer RopeSlice to &Rope in helix_core::syntaxMichael Davis2023-07-27
| | | | | | | | | | | | | | | Pascal and I discussed this and we think it's generally better to take a 'RopeSlice' rather than a '&Rope'. The code block rendering function in the markdown component module is a good example for how this can be useful: we can remove an allocation of a rope and instead directly turn a '&str' into a 'RopeSlice' which is very cheap. A change to prefer 'RopeSlice' to '&Rope' whenever the rope isn't modified would be nice, but it would be a very large diff (around 500+ 500-). Starting off with just the syntax functions seems like a nice middle-ground, and we can remove a Rope allocation because of it. Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de>
* use a single query for injectionsPascal Kuthe2023-07-17
| | | | In the past we used two separate queries for combined and normal injections. There was no real reason for this (except historical/slightly easier implementation). Instead, we now use a single query and simply check if an injection corresponds to a combined injection or not.

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

All of these were previously automatically derived: #[derive(PartialEq, Eq, PartialOrd, Ord, Hash, Debug, Clone, Copy] I have derived the minimum traits for each bitflag type.

* 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 initial highlight layer sort order (#5196)Michael Davis2023-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of this change is to remove the mutable self borrow on `HighlightIterLayer::sort_key` so that we can sort layers with the correct ordering using the `Vec::sort` function family. `HighlightIterLayer::sort_key` needs `&mut self` since it calls `Peekable::peek` which needs `&mut self`. `Vec::sort` functions only give immutable borrows of the elements to ensure the correctness of the sort. We could instead approach this by creating an eager Peekable and using that instead of `std::iter::Peekable` to wrap `QueryCaptures`: ```rust struct EagerPeekable<I: Iterator> { iter: I, peeked: Option<I::Item>, } impl<I: Iterator> EagerPeekable<I> { fn new(mut iter: I) -> Self { let peeked = iter.next(); Self { iter, peeked } } fn peek(&self) -> Option<&I::Item> { self.peeked.as_ref() } } impl<I: Iterator> Iterator for EagerPeekable<I> { type Item = I::Item; fn next(&mut self) -> Option<Self::Item> { std::mem::replace(&mut self.peeked, self.iter.next()) } } ``` This would be a cleaner approach (notice how `EagerPeekable::peek` takes `&self` rather than `&mut self`), however this doesn't work in practice because the Items emitted by the `tree_sitter::QueryCaptures` Iterator must be consumed before the next Item is returned. `Iterator::next` on `tree_sitter::QueryCaptures` modifies the `QueryMatch` returned by the last call of `next`. This behavior is not currently reflected in the lifetimes/structure of `QueryCaptures`. This fixes an issue with layers being out of order when using combined injections since the old code only checked the first range in the layer. Layers being out of order could cause missing highlights for combined-injections content.

* Bump TREE_SITTER_MATCH_LIMIT to 256 (#4830)Michael Davis2022-11-21

* Use TreeCursor to pretty-print :tree-sitter-subtree (#4606)Michael Davis2022-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current `:tree-sitter-subtree` has a bug for field-names when the field name belongs to an unnamed child node. Take this ruby example: def self.method_name true end The subtree given by tree-sitter-cli is: (singleton_method [2, 0] - [4, 3] object: (self [2, 4] - [2, 8]) name: (identifier [2, 9] - [2, 20]) body: (body_statement [3, 2] - [3, 6] (true [3, 2] - [3, 6]))) But the `:tree-sitter-subtree` output was (singleton_method object: (self) body: (identifier) (body_statement (true))) The `singleton_method` rule defines the `name` and `body` fields in an unnamed helper rule `_method_rest` and the old implementation of `pretty_print_tree_impl` would pass the `field_name` down from the named `singleton_method` node. To fix it we switch to the [TreeCursor] API which is recommended by the tree-sitter docs for traversing the tree. `TreeCursor::field_name` accurately determines the field name for the current cursor position even when the node is unnamed.

* Change syntax for suffix file-types configurations (#4414)Michael Davis2022-10-22
| | | | | | | | | | | | | | | | | The change in d801a6693c3d475b3942f705d3ef48d7966bdf65 to search for suffixes in `file-types` is too permissive: files like the tutor or `*.txt` files are now mistakenly interpreted as R or perl, respectively. This change changes the syntax for specifying a file-types entry that matches by suffix: ```toml file-types = [{ suffix = ".git/config" }] ``` And changes the file-type detection to first search for any non-suffix patterns and then search for suffixes only with the file-types entries marked explicitly as suffixes.
