PicoWiki is a super tiny and simple file-based Wiki system.

• Markdown Formatting, links, etc.
• Install in 2 seconds Just place a folder in your server
• File-based Easily editable
• Tiny Less than 100 lines of the core code
• Extensible through Plugins
• Fast Uses very low bandwidth
• Powerful You can use PHP code anywhere

See Setup for instructions.

Plugins use Event Hooks to attach new features and alter functionality on the run, a new plugin must have a run() method that will be executed whenever you specify. Check out /backend/plugins/ to find available plugins.

To disable a plugin, simply move it away from the plugins folder (also in a subfolder such as plugins/deactivated).

PicoWiki is a single PHP class with 7 methods, all in less than 100 lines of code, ready to be extended. New features I can think of right (through plugins) now are:

• Report for checking for broken links (links to pages that don't exist yet), Orphan pages, etc.
• Code snippets to load YouTube videos or Google Maps, etc.
• Web-based file editor to edit files directly via browser
• Themes
• Auto-translate
• Sitemap generator

When I say it's tiny I mean this, the whole app is just this code:
