Inspired by ShortestWikiContest, I've created WikWiki from scratch. It's 1287 characters long (17 lines) and written in PHP. WikiPrinciples are obeyed.
- Working demo: http://labs.smasty.net/WikWiki
- Highlighted & formatted source: http://labs.smasty.net/WikWiki/code.html
A new version of WikWiki with advanced features is available on GitHub: http://github.com/smasty/WikWiki
Features
- AutomaticLinkGeneration - Same behaviour as on this site
- EasyTextInput
- Four or more dash characters create horizontal rule
- Dash on a new line followed by space creates list item
- New line creates <br> tag
- URLs starting by http(s) are converted to links
- Space indented line is monospaced
- BackLinks support
Installation
No special installation is required, just copy the source.
