Extensions for Sphinx which allow substitutions within code blocks.
.. contents::
Sphinx Substitution Extensions is compatible with Sphinx 7.2.0+ using Python 3.10+.
.. code-block:: console
$ pip install Sphinx-Substitution-Extensions
- Add the following to
conf.pyto enable the extension:
.. code-block:: python
"""Configuration for Sphinx."""
extensions = ["sphinxcontrib.spelling"] # Example existing extensions
extensions += ["sphinx_substitution_extensions"]
- Set the following variable in
conf.pyto define substitutions:
.. code-block:: python
"""Configuration for Sphinx."""
rst_prolog = """ .. |release| replace:: 0.1 .. |author| replace:: Eleanor """
This will replace |release| in the new directives with 0.1, and |author| with Eleanor.
code-block
This adds a ``:substitutions:`` option to Sphinx's built-in `code-block`_ directive.
.. code-block:: rst
.. code-block:: shell
:substitutions:
echo "|author| released version |release|"
Inline ``:substitution-code:``
.. code-block:: rst
:substitution-code:echo "|author| released version |release|"
substitution-download
.. code-block:: rst
:substitution-download:`|author|'s manuscript <|author|_manuscript.txt>`
MyST Markdown setup
-------------------
1. Add ``sphinx_substitution_extensions`` to ``extensions`` in ``conf.py`` to enable the extension:
.. code-block:: python
"""Configuration for Sphinx."""
extensions = ["myst_parser"] # Example existing extensions
extensions += ["sphinx_substitution_extensions"]
2. Set the following variables in ``conf.py`` to define substitutions:
.. code-block:: python
"""Configuration for Sphinx."""
myst_enable_extensions = ["substitution"]
myst_substitutions = {
"release": "0.1",
"author": "Eleanor",
}
This will replace ``|release|`` in the new directives with ``0.1``, and ``|author|`` with ``Eleanor``.
Using substitutions in MyST Markdown
------------------------------------
``code-block``
~~~~~~~~~~~~~~
This adds a ``:substitutions:`` option to Sphinx's built-in `code-block`_ directive.
.. code-block:: markdown
```{code-block} bash
:substitutions:
echo "|author| released version |release|"
```
As well as using ``|author|``, you can also use ``{{author}}``.
This will respect the value of ``myst_sub_delimiters`` as set in ``conf.py``.
