Plugins

Editor plugins have the same names as comark's parser plugins. They add knowledge — components, completions, snippets, binding scopes, lint, hover, commands and a syntax note for agents — not machinery.

import { comark } from 'comark-codemirror'
import mermaid from 'comark-codemirror/plugins/mermaid'
import { presetBuiltins } from 'comark-codemirror/presets/builtins'
import { presetEcosystem } from 'comark-codemirror/presets/ecosystem'

comark({ plugins: [...presetBuiltins(), ...presetEcosystem(), mermaid()] })

• Defaults are registered automatically (like comark): alert, attributes, components, frontmatter, html, task-list. Disable with registerDefaultPlugins: false.
• Built-ins: presetBuiltins() or one by one from comark-codemirror/plugins/<name>.
• Ecosystem (comark-packages): presetEcosystem().
• A later plugin with the same name replaces an earlier one; enforce: 'pre' | 'post' orders them.

Each plugin has a page with what it adds.
