Compatibility#

Understand Wenmode’s current project status, Python support, Markdown coverage, and stability expectations.


Wenmode is currently beta software. The parser, renderer, rule composition, and documented extension APIs are ready for real integration work, but the project may still refine edge-case behavior and smaller public APIs before a stable 1.0 release. See Changelog for release history and upgrade notes.

For application users, the practical rule is: depend on documented presets, rules, nodes, renderer options, and plugin APIs; avoid depending on private helpers or incidental HTML formatting details not described in the docs.

Python support#

Wenmode supports Python 3.10 and newer. The test matrix and package metadata cover CPython 3.10, 3.11, 3.12, 3.13, and 3.14, plus PyPy 3.10 and 3.11.

Documentation tooling currently requires Python 3.11 or newer because the docs dependency group follows the supported versions of Sphinx and the selected theme.

Markdown coverage#

The default commonmark preset targets CommonMark-style Markdown and includes reference-style links and images. It does not include GitHub-flavored Markdown extensions.

Use the github preset for GitHub-flavored Markdown features. Wenmode runs the CommonMark and GFM spec fixture suites in its tests. Non-standard syntax is intentionally exposed through explicit wenmode.plugins modules.

Use the streaming preset when you need incremental HTML output. Streaming disables syntax that requires document-wide deferred inline resolution, such as reference-style links, reference-style images, and footnotes.

Stability expectations#

The high-level APIs documented in Usage, Presets, Plugins, and Custom Plugins are intended to be stable through the beta period:

  • Wenmode, Parser, and renderer construction, including Wenmode(..., plugins=[...]).

  • Rule classes and configured rule instances.

  • Plugin modules or objects with setup(wen, /), whether installed during Wenmode construction or later with Wenmode.use(plugin).

  • Node.to_ast() output for documented node types.

  • Custom plugin setup() functions, rules, renderer handlers, and root transform shapes.

  • Parser.parse_blocks(), Parser.parse_inlines(), Parser.is_paragraph_interrupt(), and Parser.inline_source() for custom rules that need nested parsing or paragraph-interruption checks.

  • BlockState, StateKey, StateStore, SourceMap, and source trackers from wenmode.state for custom rules that need per-parse extension state or source-position mapping.

  • Public helper modules such as wenmode.ast, wenmode.headings, and wenmode.toc.

The project may still adjust undocumented helper functions, renderer formatting details for non-HTML output, and edge-case parsing behavior where the current implementation conflicts with CommonMark, GFM, or documented Wenmode semantics.

Public and private modules#

Prefer importing public extension APIs from these modules:

  • wenmode for Wenmode, Parser, and built-in renderers.

  • wenmode.rules for rule base classes and built-in rule classes.

  • wenmode.plugins for built-in plugin modules, PluginModule, and RendererHandlers.

  • wenmode.renderers for renderer base classes, built-in renderers, contexts, and renderer handler hooks.

  • wenmode.nodes for documented node dataclasses.

  • wenmode.state for BlockState, StateKey, SourceMap, and related source tracking helpers used by custom rules.

Modules under wenmode._parser are private implementation details. They hold the compiled rule-set, block parser, inline parser, and paragraph-interruption logic used by Parser, but their classes, attributes, and helper functions are not part of the supported extension API. Custom rules should call the public Parser methods listed above instead of importing from wenmode._parser.

Migration notes#

Wenmode is not a drop-in replacement for Mistune plugins. The common Markdown-to-HTML path maps directly to Wenmode().render(), but extension behavior should be migrated by choosing a preset, using built-in plugins, and registering directive renderers or custom renderers as needed.

See Recipes for common integration patterns and Custom Plugins for custom plugins.
