Legacy components (5.6 branch, unmaintained)
| Source file | Documentation |
|---|---|
| BubbleBabble.php | (Documentation) Encodes and decodes using the Bubble Babble binary data encoding. Much like base64 but makes actually pronounceable pseudo-words. |
| CacheCookie.php | Stores session data in a cookie (using MsgPack if available or JSON as a fallback), without using session files. For MsgPack you can use this pure PHP implementation but the PECL module "msgpack" is much faster. |
| MemCache.php | memory cache wrapper (APCu, XCache, Opcache, etc.) |
| MiniSkel.php | template-based programming language compatible with the SPIP CMS |
| Singleton.php | used to make singleton classes |
| XML_RPC_Server.php | a XML/RPC server using PHP XML/RPC extension |

- Text editor: extends textareas with tools to select, insert or replace content, with support for keyboard shortcuts.
- Code editor: built on Text editor, it provides an easy to use browser code editor including: common keyboard shortcuts, search, search and replace, go to line, fullscreen editing, indentation, brackets/parenthesis matching, line counter, and more.
- Karto (alpha): Mapping/GPS tools (Mercator projection)
