Introduction

[Examples][] shows explicit examples for different syntaxes. [Other Syntaxes][] show the syntaxes that can't be shown explicitly.

Organization

  • Header levels (except possibly the last header level): features in groups
  • Last header level or a list: different syntaxes
  • TaskPaper-styled tags to indicate in what favor of Markdown such syntax is supported
    • @markdown: supported by original markdown, hence understood to be supported by all variants of markdown
    • @ghpages: GitHub-Favored Markdown, built by kramdown with GFM option. i.e. GitHub Pages' GitHub-Favored Markdown (not exhaustively tested here. See kramdown's documentation for other possible syntaxes)
    • @mmd: MultiMarkdown 
    • @pandoc: pandoc-favored markdown
    • @phpextra: PHP Markdown Extra (inspired some syntax in pandoc and mmd and gfm, not exhaustively tested here)
  • TaskPaper Tags
    • @...(partial): partial supports only
    • @...(+...): when the extension is used
    • @pandoc(--...): when the command line argument is used
    • @pandoc(parsed): not verbatim, but parsed

Note:

  • You might see <!-- \begin{comment} -->...<!-- \end{comment} -->. This is for mmd to tex to pdf use only. Ignore this.

Emphasis

  • italic or italic @markdown
  • bold or bold @markdown
  • bold italic or bold italic @markdown
  • strikethrough @pandoc
  • Small caps @pandoc @markdown(html)

CriticMarkup

@mmd

Visually it looks like emphasis. Functionally it is much more, and called Critic Markup

  • Deletions from the original text: This is {--is --}a test.
  • Additions: This {++is ++}a test.
  • Substitutions: This {~~isn't~>is~~} a test.
  • Highlighting: This is a {==test==}.
  • Comments: This is a test{>>What is it a test of?<<}.

See more at CriticMarkup---MultiMarkdown Documentation.

Horizontal Rules

@markdown


3 or more hyphens or asterisks


Break

@markdown

No break like this

Soft break
like this

Hard break

like this

Superscript & Subscript

  • x^2 @mmd
  • d~o @mmd
  • x^a+b^ @mmd @pandoc
  • xy,z @mmd @pandoc
  • Pa\ cat @pandoc

Smarty Pants

@markdown(+smartypants) @pandoc(--smart) @ghpages

  • "Example 1"
  • 'Example 2'
  • en--dash
  • em---dash
  • ellipsis...

@mmd

  • ``Example 3''

Abbreviations (PHP Markdown Extra)

@mmd @phpextra @pandoc(+abbreviations)

*[HTML]: HyperText Markup Language *[W3C]: World Wide Web Consortium *[PANDOC]: Pandoc will simply ignore this if the extension is used. A graceful fallback.

Testing abbreviations: HTML, W3C (mouseover it to see)

Lists

Compact vs Loose Lists

The following effects are the same for different kind of lists @markdown

Compact

  • test 1
  • test 2
  • test 3

Loose

  • test 1

  • test 2

  • test 3

Ordered Lists

@markdown

  1. test
  2. test
  3. test

Unordered Lists

@markdown

  • test
  • test
  • test

Nested Lists

@markdown

  • test
    • test
  • test
    1. test
    2. test
      • test
        1. test
        2. test
    3. test
  • test

Note about LaTeX output in mmd/pandoc:

  • The Maximum nesting level of lists in LaTeX is 4. The quick hack is to mix itemize and enumerate alternatively to go beyond this.

Cutoff a List

@markdown

  1. one
  2. two
  3. three
  1. uno
  2. dos
  3. tres
  • item one
  • item two
{ my code block }

List Item in a Block

@markdown

  • First paragraph.

    Continued.

  • Second paragraph. With a code block, which must be indented eight spaces:

    { code }

Metadata

Note: mmd accepts capitalized metadata keys but others do not. For maximum compatibility, author(s), title, etc. should be in lower cases.

          is treated as a single value.

TOC

Pandoc

@pandoc

Use --toc as a command argument.

MultiMarkdown

@mmd

{{TOC}}, see beginning. It preprocess the headings and generate a ToC on its own, and doesn't give instruction for LaTeX to generate one. A hack is like this:

---
...
LaTeX Input:	mmd-load-toc-setcounter
LaTeX Input:	mmd-load-toc
...
---
<!-- \begin{comment} -->
{{TOC}}
<!-- \end{comment} -->
...

Kramdown

@ghpages

# Contents
{:.no_toc}

* Will be replaced with the ToC, excluding the "Contents" header
{:toc}

Math

MathJax is assumed. MathJax has many configurable options. See MathJax TeX and LaTeX Support — MathJax 2.6 documentation.

Markdown

@markdown

Add the following at the beginning of the document:

<script type="text/javascript"
    src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_CHTML-full">
    </script>

MathJax.js is used and any codes within math delimiters are treated as raw HTML and to be processed by MathJax.

MathJax delimiter are $$...$$, \\(...\\) and \\[...\\] (because an extra \ can be used to escape from MarkDown).

Depending on the markdown parser, extra tricks might be needed to make sure nothing within the math delimiter is treated as markdown (see TeX and LaTeX in HTML documents — MathJax 2.6 documentation). $...$ can be used with MathJax configuration (see TeX and LaTeX math delimiters — MathJax 2.6 documentation).

MultiMarkdown and Pandoc

There are subtleties how math should be used in HTML+MathJax and LaTeX output from single markdown source. See more in Testing LaTeX Environments Usage in MathJax From Markdown Conversion (including mmd and pandoc).

MultiMarkdown

@mmd

Add the following metadata at the beginning of the document:

HTML header:    <script type="text/javascript"
    src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_CHTML-full">
    </script>

MultiMarkdown math delimiter are $...$, $$...$$, \\(...\\) and \\[...\\].

Pandoc

@pandoc(--mathjax)

For pandoc, add --mathjax in the command-line argument.

Default math delimiter for pandoc is $...$, $$...$$. Other options are configurable. See more in Pandoc - Pandoc User’s Guide.

Inline Math

  • $1+1$
  • \(1 + 1\) @pandoc(+tex_math_double_backslash)

Block Math

  • $$R R^T = I$$
  • \[A^T_S = B\]

Other Examples

  • $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$
  • $$ \begin{aligned} \dot{x} & = \sigma(y-x) \
    \dot{y} & = \rho x - y - xz \
    \dot{z} & = -\beta z + xy \end{aligned} $$
  • $$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
  • $$\mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \
    \frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \
    \frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0 \end{vmatrix}$$
  • $$P(E) = {n \choose k} p^k (1-p)^{n-k}$$
  • $$\frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} = 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}} {1+\ldots} } } }$$
  • $$ \begin{aligned} \nabla \times \vec{\mathbf{B}} -, \frac1c, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \
    \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \
    \nabla \times \vec{\mathbf{E}}, +, \frac1c, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \
    \nabla \cdot \vec{\mathbf{B}} & = 0 \end{aligned} $$
  • $$1 + \frac{q^2}{(1-q)}+\frac{q^6}{(1-q)(1-q^2)}+\cdots = \prod_{j=0}^{\infty}\frac{1}{(1-q^{5j+2})(1-q^{5j+3})}, \quad\quad \text{for $|q|&lt;1$}.$$

Footnotes

  1. This is a footnote

  2. Here's one with multiple blocks.

    Subsequent paragraphs are indented to show that they belong to the previous footnote.

    { some.code }
    

    The whole paragraph can be indented, or just the first line. In this way, multi-paragraph footnotes work like multi-paragraph list items.

  3. glossary: term (optional sort key) The actual definition belongs on a new line, and can continue on just as other footnotes. Note how it fallbacks gracefully in Markdown.
