+Highlighting tags are markers that denote a highlighting category.
+They are [associated](#highlight.styleTags) with parts of a syntax
+tree by a language mode, and then mapped to an actual CSS style by
+a [highlighter](#highlight.Highlighter).
+
+Because syntax tree node types and highlight styles have to be
+able to talk the same language, CodeMirror uses a mostly _closed_
+[vocabulary](#highlight.tags) of syntax tags (as opposed to
+traditional open string-based systems, which make it hard for
+highlighting themes to cover all the tokens produced by the
+various languages).
+
+It _is_ possible to [define](#highlight.Tag^define) your own
+highlighting tags for system-internal use (where you control both
+the language package and the highlighter), but such tags will not
+be picked up by regular highlighters (though you can derive them
+from standard tags to allow highlighters to fall back to those).

+This function is used to add a set of tags to a language syntax
+via [`NodeSet.extend`](#common.NodeSet.extend) or
+[`LRParser.configure`](#lr.LRParser.configure).
+
+The argument object maps node selectors to [highlighting
+tags](#highlight.Tag) or arrays of tags.
+
+Node selectors may hold one or more (space-separated) node paths.
+Such a path can be a [node name](#common.NodeType.name), or
+multiple node names (or `*` wildcards) separated by slash
+characters, as in `"Block/Declaration/VariableName"`. Such a path
+matches the final node but only if its direct parent nodes are the
+other nodes mentioned. A `*` in such a path matches any parent,
+but only a single level—wildcards that match multiple parents
+aren't supported, both for efficiency reasons and because Lezer
+trees make it rather hard to reason about what they would match.)
+
+A path can be ended with `/...` to indicate that the tag assigned
+to the node should also apply to all child nodes, even if they
+match their own style (by default, only the innermost style is
+used).
+
+When a path ends in `!`, as in `Attribute!`, no further matching
+happens for the node's child nodes, and the entire node gets the
+given style.
+
+In this notation, node names that contain `/`, `!`, `*`, or `...`
+must be quoted as JSON strings.
+
+For example:
+
+```javascript
+parser.withProps(
+  styleTags({
+    // Style Number and BigNumber nodes
+    "Number BigNumber": tags.number,
+    // Style Escape nodes whose parent is String
+    "String/Escape": tags.escape,
+    // Style anything inside Attributes nodes
+    "Attributes!": tags.meta,
+    // Add a style to all content inside Italic nodes
+    "Italic/...": tags.emphasis,
+    // Style InvalidString nodes as both `string` and `invalid`
+    "InvalidString": [tags.string, tags.invalid],
+    // Style the node named "/" as punctuation
+    '"/"': tags.punctuation
+  })
+)

+
+Because syntax tree node types and highlight styles have to be
+able to talk the same language, CodeMirror uses a mostly _closed_
+[vocabulary](#highlight.tags) of syntax tags (as opposed to
+traditional open string-based systems, which make it hard for
+highlighting themes to cover all the tokens produced by the
+various languages).
+
+It _is_ possible to [define](#highlight.Tag^define) your own
+highlighting tags for system-internal use (where you control both
+the language package and the highlighter), but such tags will not
+be picked up by regular highlighters (though you can derive them
+from standard tags to allow highlighters to fall back to those).

+
+The argument object maps node selectors to [highlighting
+tags](#highlight.Tag) or arrays of tags.
+
+Node selectors may hold one or more (space-separated) node paths.
+Such a path can be a [node name](#common.NodeType.name), or
+multiple node names (or `*` wildcards) separated by slash
+characters, as in `"Block/Declaration/VariableName"`. Such a path
+matches the final node but only if its direct parent nodes are the
+other nodes mentioned. A `*` in such a path matches any parent,
+but only a single level—wildcards that match multiple parents
+aren't supported, both for efficiency reasons and because Lezer
+trees make it rather hard to reason about what they would match.)
+
+A path can be ended with `/...` to indicate that the tag assigned
+to the node should also apply to all child nodes, even if they
+match their own style (by default, only the innermost style is
+used).
+
+When a path ends in `!`, as in `Attribute!`, no further matching
+happens for the node's child nodes, and the entire node gets the
+given style.
+
+In this notation, node names that contain `/`, `!`, `*`, or `...`
+must be quoted as JSON strings.
+
+For example:
+
+```javascript
+parser.withProps(
+  styleTags({
+    // Style Number and BigNumber nodes
+    "Number BigNumber": tags.number,
+    // Style Escape nodes whose parent is String

+    "Italic/...": tags.emphasis,
+    // Style InvalidString nodes as both `string` and `invalid`

+
+The argument object maps node selectors to [highlighting
+tags](#highlight.Tag) or arrays of tags.
+
+Node selectors may hold one or more (space-separated) node paths.
+Such a path can be a [node name](#common.NodeType.name), or
+multiple node names (or `*` wildcards) separated by slash
+characters, as in `"Block/Declaration/VariableName"`. Such a path
+matches the final node but only if its direct parent nodes are the
+other nodes mentioned. A `*` in such a path matches any parent,
+but only a single level—wildcards that match multiple parents
+aren't supported, both for efficiency reasons and because Lezer
+trees make it rather hard to reason about what they would match.)
+
+A path can be ended with `/...` to indicate that the tag assigned
+to the node should also apply to all child nodes, even if they
+match their own style (by default, only the innermost style is
+used).
+
+When a path ends in `!`, as in `Attribute!`, no further matching
+happens for the node's child nodes, and the entire node gets the
+given style.
+
+In this notation, node names that contain `/`, `!`, `*`, or `...`
+must be quoted as JSON strings.

+For example:
+
+```javascript
+parser.withProps(
+  styleTags({
+    // Style Number and BigNumber nodes
+    "Number BigNumber": tags.number,
+    // Style Escape nodes whose parent is String

+This function is used to add a set of tags to a language syntax
+via [`NodeSet.extend`](#common.NodeSet.extend) or
+[`LRParser.configure`](#lr.LRParser.configure).
+
+The argument object maps node selectors to [highlighting
+tags](#highlight.Tag) or arrays of tags.
+
+Node selectors may hold one or more (space-separated) node paths.
+Such a path can be a [node name](#common.NodeType.name), or
+multiple node names (or `*` wildcards) separated by slash
+characters, as in `"Block/Declaration/VariableName"`. Such a path
+matches the final node but only if its direct parent nodes are the
+other nodes mentioned. A `*` in such a path matches any parent,
+but only a single level—wildcards that match multiple parents
+aren't supported, both for efficiency reasons and because Lezer
+trees make it rather hard to reason about what they would match.)
+
+A path can be ended with `/...` to indicate that the tag assigned
+to the node should also apply to all child nodes, even if they
+match their own style (by default, only the innermost style is
+used).
+
+When a path ends in `!`, as in `Attribute!`, no further matching
+happens for the node's child nodes, and the entire node gets the
+given style.
+
+In this notation, node names that contain `/`, `!`, `*`, or `...`
+must be quoted as JSON strings.
+
+For example:
+
+```javascript
+parser.withProps(
+  styleTags({
+    // Style Number and BigNumber nodes
+    "Number BigNumber": tags.number,
+    // Style Escape nodes whose parent is String
+    "String/Escape": tags.escape,
+    // Style anything inside Attributes nodes
+    "Attributes!": tags.meta,
+    // Add a style to all content inside Italic nodes
+    "Italic/...": tags.emphasis,
+    // Style InvalidString nodes as both `string` and `invalid`

+# @lezer/javascript
+
+This is a JavaScript grammar for the
+[lezer](https://lezer.codemirror.net/) parser system.
+
+It parses ES2020, and supports a `"ts"`
+[dialect](https://lezer.codemirror.net/docs/guide/#dialects) to parse
+TypeScript, and a `"jsx"` dialect to parse JSX.
+
+The `top` option can be set to `"SingleExpression"` or
+`"SingleClassItem"` to parse an expression or class item instead of a
+full program.
+
+The code is licensed under an MIT license.

+[ [**WEBSITE**](http://lezer.codemirror.net) | [**ISSUES**](https://github.com/lezer-parser/lezer/issues) | [**FORUM**](https://discuss.codemirror.net/c/lezer) | [**CHANGELOG**](https://github.com/lezer-parser/lr/blob/master/CHANGELOG.md) ]
+
+Lezer ("reader" in Dutch, pronounced pretty much as laser) is an
+incremental GLR parser intended for use in an editor or similar
+system, which needs to keep a representation of the program current
+during changes and in the face of syntax errors.
+
+It prioritizes speed and compactness (both of parser table files and
+of syntax tree) over having a highly usable parse tree—trees nodes are
+just blobs with a start, end, tag, and set of child nodes, with no
+further labeling of child nodes or extra metadata.
+
+This package contains the run-time LR parser library. It consumes
+parsers generated by
+[@lezer/generator](https://github.com/lezer-parser/generator).
+
+The parser programming interface is documented on [the
+website](https://lezer.codemirror.net/docs/ref/#lr).
+
+The code is licensed under an MIT license.
+
+This project was hugely inspired by
+[tree-sitter](http://tree-sitter.github.io/tree-sitter/).
