Documentation Markup

There is a lot of special markup syntax you can use in the documentation. It is kind of a mixture of XML, LaTeX, Python doctest, and custom markup.

In the future, we plan to use more Sphinx-based documentation.

The following commands can be used to markup documentation text:

For Help Text



<dl> dl-list </dl>

a definition list with <dt> and <dd> entries.

<dt> title

the title of a description item.

<dd> description

the description of a description item.

<ul> list </ul>

an unordered list of <li> entries.

<ol> list </ol>

an ordered list of <li> entries.

<li> item `

an item of an unordered or ordered list.

' _code_ '

inline Mathics code or other code.

<console> text </console>

a console (shell/bash/Terminal) transcript in its own paragraph.

<con> text </con>

an inline console transcript.

<em> text </em>

emphasized (italic) text.

<i> text </i>

the same as <em>.

<url> url </url>

a URL.

<img src=" src " title=" title " label=" label "

an image.

<imgpng src=" srctitle=" title " label=" label "

the same as <img>.

<ref label=” label “>``

a reference to an image.


a vertical skip.

\LaTeX, \Mathematica, \Mathics

special product and company names.


a single '.

## $comment$

a comment line that is not shown in the documentation.

To include images in the documentation, use the img tag, place an EPS file src .eps in mathics.doc.documentation.images and run in the mathics.doc directory.

For Testing

The following commands can be used to specify test cases.



>> Mathics code

Some Mathics code to run and to appear in documentation.

#> Mathics code

Some Mathics code to run but not appearing documentation.

X> Mathics code

Mathics code shown in the documentation but not run.


a test query that is shown in the documentation and run if the SANDBOX environment variable is not set.

= output

expected output produced by the Mathics code.


matches any output; used when output can vary.


a newline which is expected to appear in test output.

$ name $

variable identifier in Mathics code or in text.


graphics in the test result.

: message

a message in the result of the test query.

\| print

a printed line in the result of the test query.

Todo: give examples of each of these.
