Collection of ported legacy language modes for the CodeMirror code editor
@codemirror/legacy-modes is a package that provides support for legacy modes in CodeMirror 6. It allows users to utilize syntax highlighting and other features from older versions of CodeMirror in the newer version.
Syntax Highlighting
This code sample demonstrates how to use the @codemirror/legacy-modes package to add Python syntax highlighting to a CodeMirror 6 editor instance.
import { legacyMode } from '@codemirror/legacy-modes';
import { StreamLanguage } from '@codemirror/language';
import { python } from '@codemirror/legacy-modes/mode/python';
const pythonLanguage = StreamLanguage.define(python);
const editor = new EditorView({
state: EditorState.create({
doc: 'print("Hello, World!")',
extensions: [pythonLanguage]
}),
parent: document.body
});Legacy Mode Integration
This code sample shows how to integrate JavaScript syntax highlighting from legacy CodeMirror modes into a CodeMirror 6 editor.
import { legacyMode } from '@codemirror/legacy-modes';
import { StreamLanguage } from '@codemirror/language';
import { javascript } from '@codemirror/legacy-modes/mode/javascript';
const jsLanguage = StreamLanguage.define(javascript);
const editor = new EditorView({
state: EditorState.create({
doc: 'console.log("Hello, World!");',
extensions: [jsLanguage]
}),
parent: document.body
});The 'codemirror' package is the original CodeMirror library, which includes a wide range of language modes and features for creating code editors. It is the predecessor to CodeMirror 6 and includes built-in support for many languages, but it does not have the modular architecture of CodeMirror 6.
Prism is a lightweight, extensible syntax highlighter. It is designed to be easy to extend and customize, and it supports a wide range of languages. Unlike @codemirror/legacy-modes, Prism is not tied to a specific editor and can be used in various contexts.
Highlight.js is a syntax highlighter written in JavaScript. It works in the browser as well as on the server. It is similar to @codemirror/legacy-modes in that it provides syntax highlighting for many languages, but it is not specifically designed for integration with CodeMirror.

This package implements a collection of ported stream
language modes for
the CodeMirror code editor. Each mode is
available as a separate script file, under
"@codemirror/legacy-modes/mode/[name]", and exports the values
listed below.
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.
Using modes from this package works like this:
Install this package and the
@codemirror/language
package.
Find the StreamParser instance you need in the reference below.
Add StreamLanguage.define(theParser) to your editor's
configuration.
For example, to load the Lua mode, you'd do something like...
import {StreamLanguage} from "@codemirror/language"
import {lua} from "@codemirror/legacy-modes/mode/lua"
import {EditorView, basicSetup} from "codemirror"
let view = new EditorView({
extensions: [basicSetup, StreamLanguage.define(lua)]
})
