[ WEBSITE | DOCS | ISSUES | FORUM | CHANGELOG ]

This package implements the language support infrastructure for the CodeMirror code editor.

The project page has more information, a number of examples and the documentation.

This code is released under an MIT license.

We aim to be an inclusive, welcoming community. To make that explicit, we have a code of conduct that applies to communication around the project.

Usage

Setting up a language from a Lezer parser looks like this:

1import {parser} from "@lezer/json"
2import {LRLanguage, continuedIndent, indentNodeProp,
3        foldNodeProp, foldInside} from "@codemirror/language"
4
5export const jsonLanguage = LRLanguage.define({
6  name: "json",
7  parser: parser.configure({
8    props: [
9      indentNodeProp.add({
10        Object: continuedIndent({except: /^\s*\}/}),
11        Array: continuedIndent({except: /^\s*\]/})
12      }),
13      foldNodeProp.add({
14        "Object Array": foldInside
15      })
16    ]
17  }),
18  languageData: {
19    closeBrackets: {brackets: ["[", "{", '"']},
20    indentOnInput: /^\s*[\}\]]$/
21  }
22})

Often, you'll also use this package just to access some specific language-related features, such as accessing the editor's syntax tree...

1import {syntaxTree} from "@codemirror/language"
2
3const tree = syntaxTree(view)

... or computing the appriate indentation at a given point.

1import {getIndentation} from "@codemirror/language"
2
3console.log(getIndentation(view.state, view.state.selection.main.head))
