It will +// take a text input and produce a text output in HTML (or other format). +// +// A slightly more sophisticated way to use Blackfriday is to create a Markdown +// processor and to call Parse, which returns a syntax tree for the input +// document. You can leverage Blackfriday's parsing for content extraction from +// markdown documents. You can assign a custom renderer and set various options +// to the Markdown processor. +// +// If you're interested in calling Blackfriday from command line, see +// https://github.com/russross/blackfriday-tool. +// +// 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 AutoHeadingIDs extension 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 precede 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. +package blackfriday + +// NOTE: Keep Sanitized Anchor Name algorithm in sync with package +// github.com/shurcooL/sanitized_anchor_name. +// Otherwise, users of sanitized_anchor_name will get anchor names +// that are incompatible with those generated by blackfriday. |
