I want to set up a local wiki for my personal notes. My requirements are:
- very good math support (I think mathjax like on mathoverflow should be fine)
- good search function (in particular regular expressions)
- easy to setup
- active user community
- active development
- it should run under linux
- good emacs support (i.e. it should be comfortable to edit wiki pages within emacs)
- wiki text stored in plain text would be great
- good support for embedding videos
- an editing window like in stackoverflow or mathoverflow would be great (i.e. direct preview including math formulas)
- pdf export feature (optional)
Do you have any recommendations which wiki meets this requirements best?
