Markdown showcase

A tour of the syntax this blog understands: CommonMark plus the GitHub-flavoured extensions MD4C implements.

Inline formatting

Emphasis, strong, both, strikethrough, inline code, highlight, and a link. Bare URLs such as https://github.com/mity/md4c become links automatically.

Lists

1. First
2. Second
   • Nested bullet
   • Another one
3. Third

• Task lists
• with checkboxes

Code

const md4c = await loadMd4c();
console.log(md4c.toHtml('# Hello'));

Tables

Feature	Flag	Default
Tables	TABLES	yes
Strikethrough	STRIKETHROUGH	yes
Wiki links	WIKILINKS	yes
Underline	UNDERLINE	no

Quotes and admonitions

Markdown is intended to be as easy-to-read and easy-to-write as is feasible.

Mathematics

Inline mathematics such as e^{i\pi} + 1 = 0 and display equations are typeset with KaTeX, which is loaded only for posts that contain math:

\hat{f}(\xi) = \int_{-\infty}^{\infty} f(x)\, e^{-2\pi i x \xi}\, dx

The cost of parsing a document of n bytes is O(n) for typical input.

Footnotes

MD4C supports footnotes¹, and links between posts like Welcome.
