Release Notes

executablebooks/MyST-Parser (myst_parser)

v4.0.0

Compare Source

This release bumps the supported versions of:

• Python to 3.10 and greater
• Sphinx to >=7,<9
• Docutils to >=0.19,<0.22

Additionally, footnotes are now parsed similar to the corresponding reStructuredText, in that resolution (between definitions and references) and ordering is now deferred to transforms on the doctree (in gh-pr:931).

This allows for the proper interaction with other docutils/sphinx transforms, including those that perform translations,
and logging of warnings for duplicate/unreferenced footnote definitions and also for footnote references with no definitions.

See the footnotes guide for more information.

Full Changelog: v2.0.0...v3.0.0

v2.0.0

Compare Source

This release primarily updates core myst-parser dependencies,
with some minor changes to parsing behaviour:

• ⬆️ UPGRADE: markdown-it-py to v3 (gh-pr:773)

  • This is mainly a non-breaking change, fixing some edge cases in parsing
  • See: https://github.com/executablebooks/markdown-it-py/releases/tag/v3.0.0
    and https://github.com/executablebooks/mdit-py-plugins/releases/tag/v0.4.0

• ⬆️ UPGRADE: linkify-it-py to v2 (gh-pr:675)

  • Also fixes some edge cases in parsing
  • See: https://github.com/tsutsu3/linkify-it-py/blob/main/CHANGELOG.md

• ⬆️ UPGRADE: Add support for docutils v0.20 (gh-pr:775)

  • No significant changes, see https://docutils.sourceforge.io/RELEASE-NOTES.html#release-0-20-2023-05-04

• ⬆️ UPGRADE: Add support for sphinx v7, and remove v5 support (gh-pr:776)

  • No significant changes, see https://www.sphinx-doc.org/en/master/changes/index.html

• ⬆️ UPGRADE: Remove Python 3.7 support and add testing for Python 3.11 (gh-pr:772)

• 👌 Improve default slug generation for heading anchors, thanks to gh-user:Cimbali (gh-pr:777)

  • This change makes the slug generation closer to GitHub, in that, starting/ending whitespace will not be stripped.
    For example, # ` a` b `c ` will now correctly create the slug -a-b-c- and not a-b-c

• 👌 IMPROVE: Substitution extension (gh-pr:777)

  • Allow any value type (including dict, list, datetime) and emit a myst.substitution warning for errors in resolving the substitution content.

• 🧪 Introduce a gate/check GHA job, thanks to gh-user:webknjaz (gh-pr:635)

v0.19.0

Compare Source

This release brings a number of exciting new features, improvements, and upgrades 🎉

Full Changelog: v0.18.1...v0.19.0

📚 Rewritten documentation

The documentation has been almost completely rewritten,
with a clearer structure, many more examples, rich hover tips, and a new live preview page (powered by pyscript, gh-pr:717).

The code base API is also now fully documented by sphinx-autodoc2, which even allows for MyST docstrings! (gh-pr:704).

⬆️ Add Sphinx 6 support, drop Sphinx 4

The code base has been updated to support sphinx v6, and is no longer tested against sphinx v4 (gh-pr:664)

📄 Extended docutils (single-page) support

The docutils parser now supports many more features, and improvements to support live previews:

• myst_suppress_warnings option added, mirroring Sphinx, to suppress MyST warnings (gh-pr:655)
• myst_meta_html and myst_substitutions options are now supported (gh-pr:672)
• myst_heading_anchors option is now supported (gh-pr:678)
• Math block labels syntax is now supported (gh-pr:668)
• Missing directive/role errors errors are now suppressible warnings (gh-pr:687)
• Non-fatal directive parsing errors are now suppressible warnings (gh-pr:682)
• Most of the extended markdown syntax below is also supported

🔗 Extended Markdown links

See the Extended Markdown links section for the full guide.

You can now use standard Markdown link syntax to reference many different types of targets, in a more consistent way.

• [text](relative/path/myfile.md) work as previously, to link to files,
  but they can also be relative to source directory: [text](/path/from/srcdir/myfile.md).
  You can also use <project:file.md>
• <path:myfile.txt> will link specifically to a downloadable file
• [text](#target) or <project:#target> will link (in order of priority) to any local target, local heading anchor, target in the same project, or intersphinx (inventory) target
• [text](inv:name:domain:type#target) will link specifically to a Sphinx inventory target, or to any inventory <inv:#target>, and can even use * wildcards like <inv:*:*:*#*.target>
  • This can even be used in docutils, with the new myst_inventories config option
  • The myst-inv CLI makes it easy to find the correct inventory target

:::{tip}
It is advised (although not immediately necessary) to prefix all internal references with #.
For example, [...](my-reference), should be changed to [...](#my-reference).
:::

{} Attributes syntax

The attrs_inline and attrs_block extensions allow for common Markdown syntaxes to be extended with greater control over the output.

For example, you can now add classes, ids, and other attributes to inline code, images, and links, as well as to code blocks and directives.

• Inline code: `a = 1`{#id .class l=python}
• Images: ![image](image.png){#id .class width=100px}
• Text spans: [some text]{#id .class}

A paragraph block can have attributes too:

{#id .class}
This is a paragraph with an id and class

A code fence can be given line numbers and line emphasis:

{#id .class lineno-start=1 emphasize-lines="2,3"}
```python
a = 1
b = 2
c = 3
```

A definition list can be turned into a glossary, with referenceable terms:

{.glossary}
term name
: Definition of the term

Quote blocks can be given an attribution:

{attribution="Chris Sewell"}
> My quote

👌 Miscellaneous improvements

• Nested headings (e.g. inside directives) are now allowed in MyST and are correctly rendered in HTML (gh-pr:711)
• The colon_fence extension now renders internal content as MyST, rather than as a code block (gh-pr:713)
• The include directive in MyST documents now supports a :heading-offset: option, to offset the heading levels in the included document
• The myst_heading_slug_func option now supports setting a str which points to a fully qualified function name, e.g. "module.path.func" (gh-pr:696)
• The myst_enable_checkboxes option allows for task list checkboxes to be enabled/disabled (gh-pr:686)

Additional contributions

• 🔧 ci(deps): setup dependabot (gh-pr:669), thanks to gh-user:mmorel-35

v0.18.1

Full Changelog: v0.18.0...v0.18.1

• ⬆️ UPGRADE: docutils 0.19 support in gh-pr:611
• ✨ NEW: Add attrs_image (experimental) extension in gh-pr:620
  • e.g. ![image](image.png){#id .class width=100px}
  • See: Optional syntax section
  • Important: This is an experimental extension, and may change in future releases

v0.18.0

Compare Source

Full Changelog: v0.17.2...v0.18.0

This release adds support for Sphinx v5 (dropping v3), restructures the code base into modules, and also restructures the documentation, to make it easier for developers/users to follow.

It also introduces document-level configuration via the Markdown front-matter, under the myst key.
See the Local configuration section for more information.

Breaking changes

This should not be breaking, for general users of the sphinx extension (with sphinx>3),
but will be for anyone directly using the Python API, mainly just requiring changes in import module paths.

The to_docutils, to_html, to_tokens (from myst_parser/main.py) and mock_sphinx_env/parse (from myst_parser.sphinx_renderer.py) functions have been removed, since these were primarily for internal testing.
Instead, for single page builds, users should use the docutils parser API/CLI (see ),
and for testing, functionality has been moved to https://github.com/chrisjsewell/sphinx-pytest.

The top-level html_meta and substitutions front-matter keys have also been deprecated (i.e. they will still work but will emit a warning), as they now form part of the myst config, e.g.
