What is @codemirror/lang-css?

@codemirror/lang-css is a language support package for CodeMirror 6 that provides syntax highlighting, code folding, and other editing features for CSS. It is designed to be used with the CodeMirror 6 editor, which is a versatile text editor implemented in JavaScript for the browser.

What are @codemirror/lang-css's main functionalities?

Syntax Highlighting

This code sets up a CodeMirror editor with basic syntax highlighting for CSS. The `css` function from `@codemirror/lang-css` is used to provide the CSS language support.

import { css } from '@codemirror/lang-css';
import { EditorState } from '@codemirror/state';
import { EditorView, basicSetup } from '@codemirror/basic-setup';

const state = EditorState.create({
  doc: 'body {\n  background-color: #f0f0f0;\n}',
  extensions: [basicSetup, css()]
});

const view = new EditorView({
  state,
  parent: document.body
});

Code Folding

This code sets up a CodeMirror editor with code folding capabilities for CSS. The `foldGutter` extension is used alongside the `css` function to enable folding of CSS code blocks.

import { css } from '@codemirror/lang-css';
import { foldGutter } from '@codemirror/fold';
import { EditorState } from '@codemirror/state';
import { EditorView, basicSetup } from '@codemirror/basic-setup';

const state = EditorState.create({
  doc: 'body {\n  background-color: #f0f0f0;\n  color: #333;\n}',
  extensions: [basicSetup, css(), foldGutter()]
});

const view = new EditorView({
  state,
  parent: document.body
});

Linting

This code sets up a CodeMirror editor with linting capabilities for CSS. The `linter` and `lintGutter` extensions are used alongside the `css` function to provide linting support.

import { css } from '@codemirror/lang-css';
import { linter, lintGutter } from '@codemirror/lint';
import { EditorState } from '@codemirror/state';
import { EditorView, basicSetup } from '@codemirror/basic-setup';

const cssLinter = linter(view => {
  // Custom linting logic
  return [];
});

const state = EditorState.create({
  doc: 'body {\n  background-color: #f0f0f0;\n  color: #333;\n}',
  extensions: [basicSetup, css(), lintGutter(), cssLinter]
});

const view = new EditorView({
  state,
  parent: document.body
});
