// Package blackfriday is a Markdown processor.
|
|
//
|
|
// It translates plain text with simple formatting rules into HTML or LaTeX.
|

|
|
// Sanitized Anchor Names
|
|
//
|
|
// Blackfriday includes an algorithm for creating sanitized anchor names
|
|
// corresponding to a given input text. This algorithm is used to create
|
|
// anchors for headings when EXTENSION_AUTO_HEADER_IDS is enabled. The
|
|
// algorithm is specified below, so that other packages can create
|
|
// compatible anchor names and links to those anchors.
|
|
//
|
|
// The algorithm iterates over the input text, interpreted as UTF-8,
|
|
// one Unicode code point (rune) at a time. All runes that are letters (category L)
|
|
// or numbers (category N) are considered valid characters. They are mapped to
|
|
// lower case, and included in the output. All other runes are considered
|
|
// invalid characters. Invalid characters that preceed the first valid character,
|
|
// as well as invalid character that follow the last valid character
|
|
// are dropped completely. All other sequences of invalid characters
|
|
// between two valid characters are replaced with a single dash character '-'.
|
|
//
|
|
// SanitizedAnchorName exposes this functionality, and can be used to
|
|
// create compatible links to the anchor names generated by blackfriday.
|
|
// This algorithm is also implemented in a small standalone package at
|
|
// github.com/shurcooL/sanitized_anchor_name. It can be useful for clients
|
|
// that want a small package and don't need full functionality of blackfriday.

// Otherwise, users of sanitized_anchor_name will get anchor names
|
|
// that are incompatible with those generated by blackfriday.
