Sphinx Substitution Extensions

Extensions for Sphinx which allow substitutions within code blocks.

Installation

Sphinx Substitution Extensions is compatible with Sphinx 7.2.0+ using Python 3.10+.

$ pip install Sphinx-Substitution-Extensions

rST setup

  1. Add the following to conf.py to enable the extension:

"""Configuration for Sphinx."""

extensions = ["sphinxcontrib.spelling"]  # Example existing extensions

extensions += ["sphinx_substitution_extensions"]
  1. Set the following variable in conf.py to define substitutions:

"""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.

Using substitutions in rST documents

code-block

This adds a :substitutions: option to Sphinx’s built-in code-block directive.

.. code-block:: shell
   :substitutions:

   echo "|author| released version |release|"

Inline :substitution-code:

:substitution-code:`echo "|author| released version |release|"`

substitution-download

: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:

"""Configuration for Sphinx."""

extensions = ["myst_parser"]  # Example existing extensions

extensions += ["sphinx_substitution_extensions"]
  1. Set the following variables in conf.py to define substitutions:

"""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} 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.
