93
+
Convert a snippet template to a function that can apply it.
94
+
Snippets are written using syntax like this:
95
+
96
+
"for (let ${index} = 0; ${index} < ${end}; ${index}++) {\n\t${}\n}"
97
+
98
+
Each `${}` placeholder (you may also use `#{}`) indicates a field
99
+
that the user can fill in. Its name, if any, will be the default
100
+
content for the field.
101
+
102
+
When the snippet is activated by calling the returned function,
103
+
the code is inserted at the given position. Newlines in the
104
+
template are indented by the indentation of the start line, plus
105
+
one [indent unit](https://codemirror.net/6/docs/ref/#language.indentUnit) per tab character after
106
+
the newline.
107
+
108
+
On activation, (all instances of) the first field are selected.
109
+
The user can move between fields with Tab and Shift-Tab as long as
110
+
the fields are active. Moving to the last field or moving the
111
+
cursor out of the current field deactivates the fields.
112
+
113
+
The order of fields defaults to textual order, but you can add
114
+
numbers to placeholders (`${1}` or `${1:defaultText}`) to provide
115
+
a custom order.

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 packages.
162

163
+
Specifically, it includes...

- [the default command bindings](https://codemirror.net/6/docs/ref/#commands.defaultKeymap)

- [line numbers](https://codemirror.net/6/docs/ref/#gutter.lineNumbers)

- [the undo history](https://codemirror.net/6/docs/ref/#history.history)
169

- [a fold gutter](https://codemirror.net/6/docs/ref/#fold.foldGutter)
170

- [custom selection drawing](https://codemirror.net/6/docs/ref/#view.drawSelection)
171

- [multiple selections](https://codemirror.net/6/docs/ref/#state.EditorState^allowMultipleSelections)
172

- [reindentation on input](https://codemirror.net/6/docs/ref/#language.indentOnInput)
173

- [the default highlight style](https://codemirror.net/6/docs/ref/#highlight.defaultHighlightStyle) (as fallback)

- [bracket matching](https://codemirror.net/6/docs/ref/#matchbrackets.bracketMatching)
175

- [bracket closing](https://codemirror.net/6/docs/ref/#closebrackets.closeBrackets)

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.

Highlighting tags are markers that denote a highlighting category.
1663

They are [associated](https://codemirror.net/6/docs/ref/#highlight.styleTags) with parts of a syntax
1664

tree by a language mode, and then mapped to an actual CSS style by
1665

a [highlight style](https://codemirror.net/6/docs/ref/#highlight.HighlightStyle).
1666

Because syntax tree node types and highlight styles have to be

[vocabulary](https://codemirror.net/6/docs/ref/#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](https://codemirror.net/6/docs/ref/#highlight.Tag^define) your own
1675

highlighting tags for system-internal use (where you control both
1676

the language package and the highlighter), but such tags will not

This function is used to add a set of tags to a language syntax

[`LRParser.configure`](https://lezer.codemirror.net/docs/ref#lr.LRParser.configure).
1712
+
1713
+
The argument object maps node selectors to [highlighting
1714
+
tags](https://codemirror.net/6/docs/ref/#highlight.Tag) or arrays of tags.
1715
+
1716
+
Node selectors may hold one or more (space-separated) node paths.
1717
+
Such a path can be a [node
1718
+
name](https://lezer.codemirror.net/docs/ref#common.NodeType.name),
1719
+
or multiple node names (or `*` wildcards) separated by slash
1720
+
characters, as in `"Block/Declaration/VariableName"`. Such a path
1721
+
matches the final node but only if its direct parent nodes are the
1722
+
other nodes mentioned. A `*` in such a path matches any parent,
1723
+
but only a single level—wildcards that match multiple parents
1724
+
aren't supported, both for efficiency reasons and because Lezer
1725
+
trees make it rather hard to reason about what they would match.)
1726
+
1727
+
A path can be ended with `/...` to indicate that the tag assigned
1728
+
to the node should also apply to all child nodes, even if they
1729
+
match their own style (by default, only the innermost style is
1730
+
used).
1731
+
1732
+
When a path ends in `!`, as in `Attribute!`, no further matching
1733
+
happens for the node's child nodes, and the entire node gets the
1734
+
given style.
1735
+
1736
+
In this notation, node names that contain `/`, `!`, `*`, or `...`
1737
+
must be quoted as JSON strings.
1738
+
1739
+
For example:
1740
+
1741
+
```javascript
1742
+

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

by regular language packages and themes.
1805
+
1806

This collection is heavily biased towards programming languages,
1807
+
and necessarily incomplete. A full ontology of syntactic
1808
+
constructs would fill a stack of books, and be impractical to
1809
+
write themes for. So try to make do with this set. If all else
1810
+
fails, [open an
1811
+
issue](https://github.com/codemirror/codemirror.next) to propose a
1812
+
new tag, or [define](https://codemirror.net/6/docs/ref/#highlight.Tag^define) a local custom tag for
1813
+
your use case.
1814
+
1815
+
Note that it is not obligatory to always attach the most specific
1816
+
tag possible to an element—if your grammar can't easily
1817
+
distinguish a certain type of element (such as a local variable),
1818

it is okay to style it as its more general variant (a variable).

1821

4573

Returns an extension that hides the browser's native selection and
4574
+
cursor, replacing the selection with a background behind the text
4575
+
(with the `cm-selectionBackground` class), and the
4576
+
cursors with elements overlaid over the code (using
4577
+
`cm-cursor-primary` and `cm-cursor-secondary`).
4578
+
4579
+
This allows the editor to display secondary selection ranges, and
4580
+
tends to produce a type of selection more in line with that users
4581
+
expect in a text editor (the native selection styling will often
4582
+
leave gaps between lines and won't fill the horizontal space after
4583
+
a line when the selection continues past it).
4584
+
4585
+
It does have a performance cost, in that it requires an extra DOM
4586
+
layout cycle for many updates (the selection is drawn based on DOM
4587
+
layout information that's only available after laying out the
4588
+
content).

// A style is an object that, in the simple case, maps CSS property

4958

// after it will be removed from the output, which can be useful when
4959

// providing a property multiple times, for browser compatibility
4960
+
// reasons.
4961
+
//
4962
+
// A property in a style object can also be a sub-selector, which
4963
+
// extends the current context to add a pseudo-selector or a child
4964
+
// selector. Such a property should contain a `&` character, which
4965
+
// will be replaced by the current selector. For example `{"&:before":
4966
+
// {content: '"hi"'}}`. Sub-selectors and regular properties can
4967
+
// freely be mixed in a given object. Any property containing a `&` is
4968
+
// assumed to be a sub-selector.
4969
+
//
4970
+
// Finally, a property can specify an @-block to be wrapped around the
4971
+
// styles defined inside the object that's the property's value. For
4972
+
// example to create a media query you can do `{"@media screen and
4973
+
// (min-width: 400px)": {...}}`.
