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 suppressable warnings (gh-pr:687)
• Non-fatal directive parsing errors are now suppressable 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](https://github.com/executablebooks/MyST-Parser/blob/master/relative/path/myfile.md) work as previously, to link to files, but they can also be relative to source directory: [text](https://github.com/executablebooks/MyST-Parser/blob/master/path/from/srcdir/myfile.md). You can also use <project:file.md>
• <path:myfile.txt> will link specifically to a downloadable file
• [text](https://github.com/executablebooks/MyST-Parser/blob/master/#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](https://github.com/executablebooks/MyST-Parser/blob/master/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 #.
