BBCode is an abbreviation for Bulletin Board Code, the lightweight markup language used to format posts in many message boards. It is also called forum codes. The available tags are usually indicated by rectangular brackets surrounding a keyword, and they are parsed by the message board system before being translated into a markup language that web browsers understand, usually HTML or XHTML. BBCode was devised to provide a safer, easier and more limited way of allowing users to format their messages. Programmer convenience was certainly another factor, as BBCode is very simple to implement. Previously, many message boards allowed the users to include HTML formatting, a side effect of which was that malformed HTML could disrupt the page's layout, or HTML could be used to run JavaScript leading to XSS attacks. Some implementations of BBCode have suffered problems related to the way they translate the BBCode into HTML, which could negate the security that was intended to be given by BBCode. An alternative is a properly written HTML filter (many of which are freely available). Although the basic tags of BBCode are similar in most internet forum software, there is currently no standards document for BBCode and there are consequently many incompatible variants. Some variants are case-sensitive while others are not. Some variants have tags which highlight the formatting of HTML, ASP, PHP, SQL and other markup languages and programming languages.
