Summary

Deprecates renderMath() and validateMath() from comark/plugins/math (and the framework plugins/math re-exports). They will be removed in 0.9.0.

  • No renderer uses them: @comark/html, React, Vue, Svelte and Angular Math components all call katex.renderToString directly, and ANSI doesn't use KaTeX.
  • They are the only KaTeX usage in the core parser package, which otherwise keeps parsing and rendering separate.
  • MathConfig.throwOnError is deprecated too: the parser ignores it, it only fed renderMath. MathConfig.options stays for now.

Changes

  • packages/comark/src/plugins/math.ts: @deprecated JSDoc on renderMath, validateMath, MathConfig.throwOnError, linking to the docs.
  • docs/content/4.plugins/1.built-in/math.md: new Rendering math manually section with plain katex render/validate snippets and a removal warning; throwOnError marked deprecated.
  • packages/comark/test/plugins/math.test.ts: removed tests for the deprecated helpers.

Migration

import katex from 'katex'

const html = katex.renderToString(code, { displayMode, throwOnError: false })

function isValidMath(code: string) {
  try { katex.renderToString(code, { throwOnError: true }); return true } catch { return false }
}

No runtime behavior change.

Summary by CodeRabbit

  • Documentation
    • Clarified that throwOnError is ignored by the math parser and only applies to the deprecated renderMath() helper.
    • Marked renderMath() and validateMath() as deprecated, with removal planned for version 0.9.0.
    • Added examples and guidance for using KaTeX directly to render inline or display math and validate syntax.

Both helpers are unused by every renderer and will be removed in 0.9.0. MathConfig.throwOnError is deprecated as well since the parser ignores it. Docs now show how to call katex directly.

Exclude Svelte from the framework export claim.

@comark/svelte/plugins/math exports only the default plugin, MathConfig, and Math. It does not export renderMath() or validateMath(). A Svelte user who imports either helper from this subpath receives a missing-export error.
