sphinx_parsed_codeblock

Sphinx extension adding a directive for a parsed code-block.

Intro

Have you ever tried to use markup inside a code-block? For example, to create a link from inside some code? Disappointingly, there is no such functionality in sphinx - a choice must be made between the markup (via the parsed-literal directive) and the syntax highlighting (via the code-block/sourcecode/code directive). However, with this extension, that is no longer the case! A new directive, parsed-code-block, is provided, which mixes the functionality of both, providing support for markup inside syntax-highlighted code-block.

Quickstart

The extension can be installed via pip:

pip install https://github.com/RastislavTuranyi/sphinx_parsed_codeblock

Then, by including the extension in conf.py:

extensions = ['sphinx_parsed_codeblock']

the new directive can be used anywhere in the RST documentation:

.. parsed-code-block:: yaml

    foo:
        italics: *"string"*
        bold: **12345**
        ``literal: null``
        link: :ref:`true<doc-top>`

The parsed-code-block directive is a subclass of the default code-block directive and so can be used with all the same options and arguments:

.. parsed-code-block:: yaml
    :linenos:
    :lineno-start: 5
    :emphasize-lines: 2, 4
    :caption: test
    :name: test-code-block

    foo:
        italics: *"string"*
        bold: **12345**
        ``literal: null``
        link: :ref:`true<doc-top>`

Installation

Currently, the package can only be installed via pip and from GitHub, either directly:

pip install https://github.com/RastislavTuranyi/sphinx_parsed_codeblock

or from a local copy:

git clone https://github.com/RastislavTuranyi/sphinx_parsed_codeblock.git
pip install sphinx_parsed_codeblock

However, either way, don't forget to include the extension in the conf.py:

extensions = ['sphinx_parsed_codeblock']

Functionality

This extension provides one new directive - parsed-code-block - which allows for RST markup to be used inside a syntax-highlighted code-block. All inline markup is supported:

• italics (*italics*)
• bold (**bold**)
• literal (``literal``)
• link (:ref:`link` )
• etc.

though higher-level RST such as directives will not be parsed.

Supported Output Formats

• HTML

For all other formats, the parsed-code-block is treated the same as parsed-literal, so output will be produced, but without syntax highlighting.
