Queries + +Helix uses `rainbows.scm` tree-sitter query files to provide rainbow bracket +functionality. + +Tree-sitter queries are documented in the tree-sitter online documentation. +If you're writing queries for the first time, be sure to check out the section +on [syntax highlighting queries] and on [query syntax]. + +Rainbow queries have two captures: `@rainbow.scope` and `@rainbow.bracket`. +`@rainbow.scope` should capture any node that increases the nesting level +while `@rainbow.bracket` should capture any bracket nodes. Put another way: +`@rainbow.scope` switches to the next rainbow color for all nodes in the tree +under it while `@rainbow.bracket` paints captured nodes with the current +rainbow color. + +For an example, let's add rainbow queries for the tree-sitter query (TSQ) +language itself. These queries will go into a +`runtime/queries/tsq/rainbows.scm` file in the repository root. + +First we'll add the `@rainbow.bracket` captures. TSQ only has parentheses and +square brackets: + +```tsq +["(" ")" "[" "]"] @rainbow.bracket +``` + +The ordering of the nodes within the alternation (square brackets) is not +taken into consideration. + +> Note: Why are these nodes quoted? Most syntax highlights capture text +> surrounded by parentheses. These are _named nodes_ and correspond to the +> names of rules in the grammar. Brackets are usually written in tree-sitter +> grammars as literal strings, for example: +> +> ```js +> { +> // ... +> arguments: seq("(", repeat($.argument), ")"), +> // ... +> } +> ``` +> +> Nodes written as literal strings in tree-sitter grammars may be captured +> in queries with those same literal strings. + +Then we'll add `@rainbow.scope` captures. The easiest way to do this is to +view the `grammar.js` file in the tree-sitter grammar's repository. For TSQ, +that file is [here][tsq grammar.js]. As we scroll down the `grammar.js`, we +see that the `(alternation)`, (L36) `(group)` (L57), `(named_node)` (L59), +`(predicate)` (L87) and `(wildcard_node)` (L97) nodes all contain literal +parentheses or square brackets in their definitions. These nodes are all +direct parents of brackets and happen to also be the nodes we want to change +to the next rainbow color, so we capture them as `@rainbow.scope`. + +```tsq +[ + (group) + (named_node) + (wildcard_node) + (predicate) + (alternation) +] @rainbow.scope +``` + +This strategy works as a rule of thumb for most programming and configuration +languages. Markup languages can be trickier and may take additional +experimentation to find the correct nodes to use for scopes and brackets. + +The `:tree-sitter-subtree` command shows the syntax tree under the primary +selection in S-expression format and can be a useful tool for determining how +to write a query. + +### Properties + +The `rainbow.include-children` property may be applied to `@rainbow.scope` +captures. By default, all `@rainbow.bracket` captures must be direct descendant +of a node captured with `@rainbow.scope` in a syntax tree in order to be +highlighted. The `rainbow.include-children` property disables that check and +allows `@rainbow.bracket` captures to be highlighted if they are direct or +indirect descendants of some node captured with `@rainbow.scope`. + +For example, this property is used in the HTML rainbow queries. + +For a document like `<a>link</a>`, the syntax tree is: + +```tsq +(element ; <a>link</a> + (start_tag ; <a> + (tag_name)) ; a + (text) ; link + (end_tag ; </a> + (tag_name))) ; a +``` + +If we want to highlight the `<`, `>` and `</` nodes with rainbow colors, we +capture them as `@rainbow.bracket`: + +```tsq +["<" ">" "</"] @rainbow.bracket +``` + +And we capture `(element)` as `@rainbow.scope` because `(element)` nodes nest +within each other: they increment the nesting level and switch to the next +color in the rainbow. + +```tsq +(element) @rainbow.scope +``` + +But this combination of `@rainbow.scope` and `@rainbow.bracket` will not +highlight any nodes. `<`, `>` and `</` are children of the `(start_tag)` and +`(end_tag)` nodes. We can't capture `(start_tag)` and `(end_tag)` as +`@rainbow.scope` because they don't nest other elements. We can fix this case +by removing the requirement that `<`, `>` and `</` are direct descendants of +`(element)` using the `rainbow.include-children` property. + +```tsq +((element) @rainbow.scope + (#set! rainbow.include-children)) +``` + +With this property set, `<`, `>`, and `</` will highlight with rainbow colors +even though they aren't direct descendents of the `(element)` node. + +`rainbow.include-children` is not necessary for the vast majority of programming +languages. It is only necessary when the node that increments the nesting level +(changes rainbow color) is not the direct parent of the bracket node. + +[syntax highlighting queries]: https://tree-sitter.github.io/tree-sitter/syntax-highlighting#highlights +[query syntax]: https://tree-sitter.github.io/tree-sitter/using-parsers#pattern-matching-with-queries +[tsq grammar.js]: https://github.com/the-mikedavis/tree-sitter-tsq/blob/48b5e9f82ae0a4727201626f33a17f69f8e0ff86/grammar.js diff --git a/book/src/languages.md b/book/src/languages.md index dd93fec5..a0fe2299 100644 --- a/book/src/languages.md +++ b/book/src/languages.md @@ -71,6 +71,8 @@ These configuration keys are available: | `text-width` | Maximum line length.
