I'm going to be building a simple blog for myself.

Partially I just want something really simple and customizable, and also it will be a fun little programming project.

I'll be using PHP and mySQL for the backend. I won't be using any sort of framework as it shouldn't be necessary for a very simple blog. I'm fairly comfortable with JavaScript.

What I'm imagining is some sort of JavaScript library I can just download, link to my html and then turn a textarea into a simple wysiwyg editor. It could be as simple as a markdown editor or something with a little more features.

It has to be free. Open source would be a plus.

If anyone has any recommendations or advice I would be very grateful. Thanks!

I'm currently developing a minimal userscript manager who's main goal is to be fully auditable by any user in only ten minutes or so - my prototype uses less than 300 lines of javascript, and I'm trying to keep it that way.

To get the codebase this small, however, I have to be very picky with what features I implement - most notably, the code editor has to be very barebones. Are there any features that I'd be shooting myself in the foot by not including?

For example:

• syntax highlighting
• cloud sync
• regex url matching
• fullscreen editor (currently, it's just a browser popup - the intention is that you write code elsewhere and paste it in)

Any feedback is greatly appreciated!
