SaneHeaders is an extension that alters the default hashed headers extension to require headers to have spaces after the hashes (
#) in order to be recognized as headers. This allows for other extension syntaxes to use
# in their syntaxes as long as no spaces follow the
# at the beginning of a line. For instance, MagicLink's issue syntax issue syntax uses hashes followed by numbers (
#998) to represent issue links. There may extensions that use names after hashes to provide tags (
#tag). With SaneHeaders, these syntaxes can coexist. Those familiar with CommonMark may recognize this behavior.
import markdown md = markdown.Markdown(extensions=['pymdownx.saneheaders'])
The syntax when using SaneHeaders is exactly like Python Markdown's default logic with the only exception being that SaneHeaders will not treat hashes at the beginning of a line as a header if they do not have space after them.
In Python Markdown, both of these are treated as headers:
## Header ##Also a Header
With SaneHeaders, only the first is a header:
## Header ##Not a Header
