I'm not a big fan of databases. When I wrote the very first version of this site, I used a database, but it seemed silly and overkill for something that doesn't actually need to store more than static text. Static text is what you have static text files for, right?

So, I made a blog platform using only static text files. Posts are written using Markdown, metadata is stored using Markdown2's metadata extension, and are thus fully human-readable and safe from database corruption/crashes.

Fileblog puts only one constraint on your post syntax: the first non-blank line (after an eventual metadata block) must be a title (underlined with =====).

Also, since file modification timestamps are rather fragile things (a simple touch or move is enough to reset it) and only Mac OS X stores creation time, Fileblog needs to store the timestamp in the file. This is done with a line like ! 27 Apr 2013, 15:14 inserted at the start of a file upon first viewing it.
I recommend you to create a blank file, view it to get an autogenerated timestamp, then open and edit it. Before publishing, remember to delete the old timestamp and view it to get a new one. And not to overwrite the new one by saving over it.

Make sure the cache directory is writable by the web server. It'll probably default to be writable only by you.
