  // A style is an object that, in the simple case, maps CSS property
  // names to strings holding their values, as in `{color: "red",
  // fontWeight: "bold"}`. The property names can be given in
  // camel-case—the library will insert a dash before capital letters
  // when converting them to CSS.
  //
  // If you include an underscore in a property name, it and everything
  // after it will be removed from the output, which can be useful when
  // providing a property multiple times, for browser compatibility
  // reasons.
  //
  // A property in a style object can also be a sub-selector, which
  // extends the current context to add a pseudo-selector or a child
  // selector. Such a property should contain a `&` character, which
  // will be replaced by the current selector. For example `{"&:before":
  // {content: '"hi"'}}`. Sub-selectors and regular properties can
  // freely be mixed in a given object. Any property containing a `&` is
  // assumed to be a sub-selector.
  //
  // Finally, a property can specify an @-block to be wrapped around the
  // styles defined inside the object that's the property's value. For
  // example to create a media query you can do `{"@media screen and
  // (min-width: 400px)": {...}}`.

  /**
  This function is used to add a set of tags to a language syntax
  via
  [`Parser.configure`](https://lezer.codemirror.net/docs/ref#lezer.Parser.configure).
  
  The argument object maps node selectors to [highlighting
  tags](https://codemirror.net/6/docs/ref/#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](https://lezer.codemirror.net/docs/ref#tree.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
    })
  )

  The default set of highlighting [tags](https://codemirror.net/6/docs/ref/#highlight.Tag^define) used

  fails, [open an

  /**
  Convert a snippet template to a function that can apply it.
  Snippets are written using syntax like this:
  
      "for (let ${index} = 0; ${index} < ${end}; ${index}++) {\n\t${}\n}"
  
  Each `${}` placeholder (you may also use `#{}`) indicates a field
  that the user can fill in. Its name, if any, will be the default
  content for the field.
  
  When the snippet is activated by calling the returned function,
  the code is inserted at the given position. Newlines in the
  template are indented by the indentation of the start line, plus
  one [indent unit](https://codemirror.net/6/docs/ref/#language.indentUnit) per tab character after
  the newline.
  
  On activation, (all instances of) the first field are selected.
  The user can move between fields with Tab and Shift-Tab as long as
  the fields are active. Moving to the last field or moving the
  cursor out of the current field deactivates the fields.
  
  The order of fields defaults to textual order, but you can add
  numbers to placeholders (`${1}` or `${1:defaultText}`) to provide
  a custom order.
