Scanty is blogging software. Software for my blog, to be exact: adam.blog.heroku.com
It is not a blogging engine, but it's small and easy to modify, so it could be the starting point for your blog, too.
Markdown (via Maruku)
Ruby code syntax highlighting (via Syntax)
Comments via Disqus
Web framework = Sinatra
ORM = Sequel
$ gem install sinatra
Sequel, Maruku, and Syntax are all vendored.
Edit main.rb and change the Blog config struct at the top to your liking. For security purposes, change the admin password and the admin cookie key and value. These last two can be set to any random value you like, just choose something other than the default.
Then run the server:
$ ruby main.rb
And visit: localhost:4567
Log in with the password you selected, then click New Post. The rest should be self-explanatory.
In production, you'll probably want to run “rake start” to start (and restart) the server. Change the value of “port” at the top of the Rakefile to run on a different port.
The default is a SQLite file named blog.db. To use something else, set DATABASE_URL in your environment when running the app, i.e.:
$ DATABASE_URL='mysql://localhost/myblog' ruby main.rb
Or, modify the Sequel.connect statement at the top of main.rb.
The database will be created automatically when the server is executed.
There are no comments by default. If you wish to activate comments, create an account and a website on Disqus (disqus.com) and enter the website shortname as the :disqus_shortname value in the Blog config struct.
Christopher Swenson has a Wordpress importer: github.com/swenson/scanty_wordpress_import
Other kinds of data can be imported easily, take a look at the rake task :import for an example of loading from a YAML file with field names that match the database schema.
There are no themes or settings beyond the basic ones in the Blog struct. Just edit the CSS or the code as you see fit.
