Render_Markdown.Py

Renders markdown content as html. This may be markdown files loaded in by way of the load plugin.

Markdown backend

There are 3 supported markdown backends that you can configure markata to use by setting the markdown_backend in your markata.toml.

markata.toml







## choose your markdown backend
# markdown_backend='markdown'
# markdown_backend='markdown2'
markdown_backend='markdown-it-py'

markdown-it-py configuration

markdown-it-py has quite a bit of configuration that you can do, you can read more about the settings in their docs.

markata.toml







# markdown_it flavor
[markata.markdown_it_py]
config='gfm-like'

You can enable and disable built in plugins using the enable and disable lists.

markata.toml







[markata.markdown_it_py]
# markdown_it built-in plugins
enable = [ "table" ]
disable = [ "image" ]

You can configure the options_update as follows, this is for the built-in plugins and core configuration.

markata.toml







[markata.markdown_it_py.options_update]
linkify = true
html = true
typographer = true
highlight = 'markata.plugins.md_it_highlight_code:highlight_code'

Lastly you can add external plugins as follows. Many of the great plugins that come from executable_books actually comes from a separate library mdit-py-plugins, so they will be configured here.
