=========
rst2html5
rst2html5 generates (X)HTML5 documents from standalone reStructuredText sources.
It is a complete rewrite of the docutils' rst2html and uses new HTML5 constructs such as
:code:<section>
and :code:<aside>
.
Installation
.. code-block:: bash
$ pip install rst2html5
Usage
.. code-block:: bash
$ rst2html5 [options] SOURCE [DEST]
Options:
--no-indent Don't indent output
--stylesheet=
Specify a stylesheet URL to be included.
(This option can be used multiple times)
--stylesheet-inline=
Specify a stylesheet file whose contents will be
included into the output HTML file. (This option can
be used multiple times)
--script= Specify a script URL to be included.
(This option can be used multiple times)
--script-defer=
Specify a script URL with a defer attribute
to be included in the output HTML file.
(This option can be used multiple times)
--script-async=
Specify a script URL with a async attribute
to be included in the output HTML file.
(This option can be used multiple times)
--html-tag-attr=
Specify a html tag attribute.
(This option can be used multiple times)
--template=
Specify a filename or text to be used as the HTML5
output template. The template must have the {head} and
{body} placeholders. The "<html{html_attr}>"
placeholder is recommended.
--define= Define a case insensitive identifier to be used with
ifdef and ifndef directives. There is no value
associated with an identifier. (This option can be
used multiple times)
If DEST
is not provided, the output is send to stdout
.
Example
Consider a file called example.rst
that contains:
.. code-block:: rst
Title
=====
Some text and a target to `Title 2`_. **strong emphasis**:
* item 1
* item 2
Title 2
=======
.. parsed-literal::
Inline markup is supported, e.g. *emphasis*, **strong**, ``literal
text``,
_`hyperlink targets`, and `references <http://www.python.org/>`_
The command to produce an example.html
output file is::
$ rst2html5 example.rst example.html
The HTML5 produced is clean and tidy:
.. code-block:: html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
</head>
<body>
<section id="title">
<h1>Title</h1>
<p>Some text and a target to <a href="#title-2">Title 2</a>. <strong>strong emphasis</strong>:</p>
<ul>
<li>item 1</li>
<li>item 2</li>
</ul>
</section>
<section id="title-2">
<h1>Title 2</h1>
<pre>Inline markup is supported, e.g. <em>emphasis</em>, <strong>strong</strong>, <code>literal
text</code>,
<a id="hyperlink-targets">hyperlink targets</a>, and <a href="http://www.python.org/">references</a></pre>
</section>
</body>
</html>
Stylesheets and Scripts
No stylesheets or scripts are spread over the HTML5 by default.
However stylesheets and javascripts URLs or paths can be included through stylesheet
and script
options:
.. parsed-literal::
$ rst2html5 example.rst \\
**--stylesheet** https://example.com/css/default.css \\
**--stylesheet-inline** css/simple.css \\
**--script** ``https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js``
**--script-defer** ``js/test1.js``
**--script-async** ``js/test2.js``
.. code-block:: html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="https://example.com/css/default.css" />
<style>h1 {font-size: 20em}
img.icon {
width: 48px;
height: 48px;
}
h2 {color: red}
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script src="js/test1.js" defer="defer"></script>
<script src="js/test2.js" async="async"></script>
</head>
...
HTML tag attributes can be included through html-tag-attr
option:
.. parsed-literal::
$ rst2html5 **--html-tag-attr** 'lang="pt-BR"' example.rst
.. code-block:: html
<!DOCTYPE html>
<html lang="pt-BR">
...
Templates
Custom HTML5 template via the :literal:--template
option. Example:
.. parsed-literal::
$ template='<!DOCTYPE html>
<html{html_attr}>
<head>{head} <!-- custom links and scripts -->
<link href="css/default.css" rel="stylesheet" />
<link href="css/pygments.css" rel="stylesheet" />
<script src="http\://code.jquery.com/jquery-latest.min.js"></script>
</head>
<body>{body}</body>
</html>'
$ echo 'one line' > example.rst
$ rst2html5 **--template "$template"** example.rst
.. code-block:: html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<!-- custom links and scripts -->
<link href="css/default.css" rel="stylesheet" />
<link href="css/pygments.css" rel="stylesheet" />
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
</head>
<body>
<p>one line</p>
</body>
</html>
New Directives
define
, undef
, ifdef
and ifndef
:code:rst2html5
provides some new directives: define
, undef
, ifdef
and ifndef
,
similar to those used in C++.
They allow to conditionally include (or not) some rst snippets:
.. code-block:: rst
.. ifdef:: x
this line will be included if 'x' was previously defined
In case of you check two or more identifiers,
there must be an operator ([and | or]
) defined:
.. code-block:: rst
.. ifdef:: x y z
:operator: or
This line will be included only if 'x', 'y' or 'z' is defined.
stylesheet
and script
From rst2html5 1.9, you can include stylesheets and scripts via directives inside a reStructuredText text:
.. code-block:: rst
Just an ordinary paragraph.
.. stylesheet:: css/default.css
.. stylesheet:: https://pronus.io/css/standard.css
.. script:: http://code.jquery.com/jquery-latest.min.js
.. script:: slide.js
:defer:
.. script:: test/animations.js
:async:
Another paragraph
.. code-block:: html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<link href="css/default.css" rel="stylesheet" />
<link href="https://pronus.io/css/standard.css" rel="stylesheet" />
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script src="slide.js" defer="defer"></script>
<script src="test/animations.js" async="async"></script>
</head>
<body>
<p>Just an ordinary paragraph.</p>
<p>Another paragraph</p>
</body>
</html>
template
There also is a :code:template
directive. The usage is:
.. code-block:: rst
.. template:: filename
or
.. template::
template content here.
New Roles
:abbr:
From MDN Web Docs <https://developer.mozilla.org/en-US/docs/Web/HTML/Element/abbr>
_:
The HTML Abbreviation element (:code:`<abbr>`) represents an abbreviation or acronym;
the optional title attribute can provide an expansion or description for the abbreviation.
If present, title must contain this full description and nothing else.
To create an abbreviation in rst2html5
use the :abbr:
role:
.. code:: rst
* :abbr:`SPA (Single-Page Application)`
* :abbr:`ASGI (Asynchronous Server Gateway Interface)` is a spiritual successor to :abbr:`WSGI`
* :abbr:`WSGI (Web Server Gateway Interface)`
Resulting in:
.. code:: html
<ul>
<li>
<abbr title="Single-Page Application">SPA</abbr>
</li>
<li>
<abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>
is a spiritual successor to
<abbr>WSGI</abbr>
</li>
<li>
<abbr title="Web Server Gateway Interface">WSGI</abbr>
</li>
</ul>
Note that if the abbreviation follows the pattern ABBR (Description for the abbreviation)
,
the description is extracted and becomes the title
.
How To Use rst2html5 Programmatically
You should use rst2html5.HTML5Writer
with one of the publish_*` methods available in
docutils.core. In the case that the input and output will be in memory,
publish_parts`` is the best fit:
.. code:: python
from docutils.core import publish_parts
from rst2html5 import HTML5Writer
text = r'''The area of a circle is :math:`A_\text{c} = (\pi/4) d^2`.
.. math::
\frac{ \sum_{t=0}^{N}f(t,k) }{N}
'''
override = {
'html_tag_attr': ['lang="pt-BR"'],
'stylesheet': ['https://example.com/css/default.css'],
'script': [('https://blog.pronus.xyz/test.js', 'async')],
}
html = publish_parts(writer=HTML5Writer(), source=text, settings_overrides=override)['whole']
print(html)
Resulting in:
.. code:: html
<!DOCTYPE html>
<html lang="pt-BR">
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="https://example.com/css/default.css" />
<script src="https://blog.pronus.xyz/test.js" async="async"></script>
<script src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
</head>
<body>
<p>The area of a circle is
<span class="math">\(A_\text{c} = (\pi/4) d^2\)</span>
.</p>
<div class="math">\(\frac{ \sum_{t=0}^{N}f(t,k) }{N}\)</div>
</body>
</html>
.. attention::
Version 2.0 renames the module ``rst2html5_`` back to ``rst2html5``
since the conflict with docutils installation is solved.
Importing ``rst2html5_.HTML5Writer`` still works though.
See the section "**Workaround to Conflicts with Docutils**"
on ``docs/design_notes.rst`` for more information.
