This replaces @Janmm14's github.com/github-linguist/linguist/issues/3516:

Please see the guidelines to add support for a new language to Linguist. If bbcode meets the requirement on in-the-wild usage, don't hesitate to open a pull request.

Language name

BBCode

URL of example repository

Because BBCode is utilised extensively across phpBB and vBulletin forums, its primary use case is in code snippets, like gist.github.com/betaveros/48588f5443ea664e3912/6d2a86a3d426a2f94b8b1d2671fa572fc3119e2c.

However, because the language can also be defined inline, with CommonMark's ~~~CSV equivalent to a <pre><code>, its absence causes github/markup/issues/1851.
