reStructuredText renderer

New in version 1.1.0.

reStructuredText is an easy-to-read, what-you-see-is-what-you-get plaintext markup syntax and parser system.

Note

This widget requires docutils package to run. Install it with pip.

Warning

This widget is highly experimental. The whole styling and implementation are not stable until this warning has been removed.

Usage with Text

text = """
.. _top:

Hello world
===========

This is an **emphased text**, some ``interpreted text``.
And this is a reference to top_::

    $ print("Hello world")

"""
document = RstDocument(text=text)

The rendering will output:

_images/rstdocument.png

Usage with Source

You can also render a rst file using the RstDocument.source property:

document = RstDocument(source='index.rst')

You can reference other documents with the role :doc:. For example, in the document index.rst you can write:

Go to my next document: :doc:`moreinfo.rst`

It will generate a link that, when clicked, opens the moreinfo.rst document.

class kivy.uix.rst.RstDocument(**kwargs)[source]

Bases: kivy.uix.scrollview.ScrollView

Base widget used to store an Rst document. See module documentation for more information.

background_color

Specifies the background_color to be used for the RstDocument.

New in version 1.8.0.

background_color is an AliasProperty for colors[‘background’].

base_font_size

Font size for the biggest title, 31 by default. All other font sizes are derived from this.

New in version 1.8.0.

colors

Dictionary of all the colors used in the RST rendering.

Warning

This dictionary is needs special handling. You also need to call RstDocument.render() if you change them after loading.

colors is a DictProperty.

document_root

Root path where :doc: will search for rst documents. If no path is given, it will use the directory of the first loaded source file.

document_root is a StringProperty and defaults to None.

goto(ref, *largs)[source]

Scroll to the reference. If it’s not found, nothing will be done.

For this text:

.. _myref:

This is something I always wanted.

You can do:

from kivy.clock import Clock
from functools import partial

doc = RstDocument(...)
Clock.schedule_once(partial(doc.goto, 'myref'), 0.1)

Note

It is preferable to delay the call of the goto if you just loaded the document because the layout might not be finished or the size of the RstDocument has not yet been determined. In either case, the calculation of the scrolling would be wrong.

You can, however, do a direct call if the document is already loaded.

New in version 1.3.0.

preload(filename, encoding='utf-8', errors='strict')[source]

Preload a rst file to get its toctree and its title.

The result will be stored in toctrees with the filename as key.

render()[source]

Force document rendering.

resolve_path(filename)[source]

Get the path for this filename. If the filename doesn’t exist, it returns the document_root + filename.

show_errors

Indicate whether RST parsers errors should be shown on the screen or not.

show_errors is a BooleanProperty and defaults to False.

source

Filename of the RST document.

source is a StringProperty and defaults to None.

source_encoding

Encoding to be used for the source file.

source_encoding is a StringProperty and defaults to utf-8.

Note

It is your responsibility to ensure that the value provided is a valid codec supported by python.

source_error

Error handling to be used while encoding the source file.

source_error is an OptionProperty and defaults to strict. Can be one of ‘strict’, ‘ignore’, ‘replace’, ‘xmlcharrefreplace’ or ‘backslashreplac’.

text

RST markup text of the document.

text is a StringProperty and defaults to None.

title

Title of the current document.

title is a StringProperty and defaults to ‘’. It is read-only.

toctrees

Toctree of all loaded or preloaded documents. This dictionary is filled when a rst document is explicitly loaded or where preload() has been called.

If the document has no filename, e.g. when the document is loaded from a text file, the key will be ‘’.

toctrees is a DictProperty and defaults to {}.

underline_color

underline color of the titles, expressed in html color notation

underline_color is a StringProperty and defaults to ‘204a9699’.
