Documentation
Regdown adds three major features to Markdown to support making federal regulations easier to navigate and read.
Labeled Paragraphs
{label} Paragraph text
Each paragraph can have a defined label, using {label}
syntax at the start of the paragraph. This is translated into an id
attribute on the resulting HTML paragraph element. If no label is given, the contents of the paragraph are hashed to generate a unique id
for that paragraph. This makes any paragraph in the text directly linkable.
Pseudo Forms
Form field: __
__Form Field
inline__fields__
Example print forms, where the \_\_
indicate a space for hand-written input. Can be any number of underscores between 2 and 50.
Section symbols
§ 1024.5(d)
§1024.5(d)
Section symbols will always have a non-breaking space ( ) inserted between them and whatever follows to avoid hanging a symbol at the end of a line.
Block references
see(label)
Insert the contents of labeled paragraphs in other Regdown documents inline into the current document.
References can be placed before or after paragraphs. These references are to labeled paragraphs in other Markdown documents. When a contents_resolver
callback and url_resolver
callback are provided, the text of those other paragraphs can be looked up and inserted inline into the document making the reference. If render_block_reference
callback is provided, custom rendering of the referenced text to HTML can be performed.
Callbacks:
-
contents_resolver(label)
: resolve the paragraph label and return the Markdown contents of that paragraph if the paragraph exists. -
url_resolver(label)
: resolve the paragraph label and return a URL to that paragraph if the paragraph exists. -
render_block_reference(contents, url=None)
: render the contents of a block reference to HTML. The url to the reference may be give as a keyword argument ifurl_resolver
is provided.
from regdown import regdown
def my_contents_resolver(label):
# Lookup the document that contains the given label …
return corresponding_markdown_text
def my_block_renderer(block_markdown_contents, url=None):
# Render the block to HTML
return block_html
regdown(
text,
contents_resolver=my_contents_resolver,
render_block_reference=my_block_renderer
)
