cursors with elements overlaid over the code (using
`cm-cursor-primary` and `cm-cursor-secondary`).

This allows the editor to display secondary selection ranges, and
tends to produce a type of selection more in line with that users
expect in a text editor (the native selection styling will often
leave gaps between lines and won't fill the horizontal space after
a line when the selection continues past it).

It does have a performance cost, in that it requires an extra DOM
layout cycle for many updates (the selection is drawn based on DOM
layout information that's only available after laying out the
content).

Set up a hover tooltip, which shows up when the pointer hovers
over ranges of text. The callback is called when the mouse hovers
over the document text. It should, if there is a tooltip
associated with position `pos`, return the tooltip description
(either directly or in a promise). The `side` argument indicates
on which side of the position the pointer is—it will be -1 if the
pointer is before the position, 1 if after the position.

Note that all hover tooltips are hosted within a single tooltip
container element. This allows multiple tooltips over the same
range to be "merged" together without overlapping.

The return value is a valid [editor extension](https://codemirror.net/6/docs/ref/#state.Extension)
but also provides an `active` property holding a state field that
can be used to read the currently active tooltips produced by this
extension.

/**
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.configure({props: [
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
})

This is an extension value that just pulls together a number of
extensions that you might want in a basic editor. It is meant as a
convenient helper to quickly set up CodeMirror without installing
and importing a lot of separate packages.

Specifically, it includes...

- [the default command bindings](https://codemirror.net/6/docs/ref/#commands.defaultKeymap)
- [line numbers](https://codemirror.net/6/docs/ref/#view.lineNumbers)
- [special character highlighting](https://codemirror.net/6/docs/ref/#view.highlightSpecialChars)
- [the undo history](https://codemirror.net/6/docs/ref/#commands.history)
- [a fold gutter](https://codemirror.net/6/docs/ref/#language.foldGutter)
- [custom selection drawing](https://codemirror.net/6/docs/ref/#view.drawSelection)
- [drop cursor](https://codemirror.net/6/docs/ref/#view.dropCursor)
- [multiple selections](https://codemirror.net/6/docs/ref/#state.EditorState^allowMultipleSelections)
- [reindentation on input](https://codemirror.net/6/docs/ref/#language.indentOnInput)
- [the default highlight style](https://codemirror.net/6/docs/ref/#language.defaultHighlightStyle) (as fallback)
- [bracket matching](https://codemirror.net/6/docs/ref/#language.bracketMatching)
- [bracket closing](https://codemirror.net/6/docs/ref/#autocomplete.closeBrackets)
- [autocompletion](https://codemirror.net/6/docs/ref/#autocomplete.autocompletion)
- [rectangular selection](https://codemirror.net/6/docs/ref/#view.rectangularSelection) and [crosshair cursor](https://codemirror.net/6/docs/ref/#view.crosshairCursor)
- [active line highlighting](https://codemirror.net/6/docs/ref/#view.highlightActiveLine)
- [active line gutter highlighting](https://codemirror.net/6/docs/ref/#view.highlightActiveLineGutter)
- [selection match highlighting](https://codemirror.net/6/docs/ref/#search.highlightSelectionMatches)
- [search](https://codemirror.net/6/docs/ref/#search.searchKeymap)
- [linting](https://codemirror.net/6/docs/ref/#lint.lintKeymap)

(You'll probably want to add some language package to your setup
too.)

This extension does not allow customization. The idea is that,
once you decide you want to configure your editor more precisely,
you take this package's source (which is just a bunch of imports
and an array literal), copy it into your own code, and adjust it
as desired.
