The html library

Overview

The html library provides functions for escaping and unescaping HTML text.

Modules

("html")

Functions

escapeString(s string) -> string

escapeString escapes special characters like '<' to become "<". It escapes only five such characters: <, >, &, ' and ". unescapeString(escapeString(s)) == s always holds, but the converse isn't always true.

unescapeString(s string) -> string

unescapeString unescapes entities like "<" to become '<'. It unescapes a larger range of entities than escapeString escapes. For example, "á" unescapes to 'á', as does "á" and "á". unescapeString(escapeString(s)) == s always holds, but the converse isn't always true.
