Scanty, a really small blog, using the Redis database

Overview

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.

This fork modifies lib/post.rb to use Redis, a featureful key-value database, instead of SQL.

Dependencies

Dependencies are all handled through bundler.

$ bundle install

See redis.io for directions on installing and configuring a redis server.

Setup

Edit main.rb and change the Blog config struct at the top to your liking, or set the appropriate environmant variables. To run the server:

$ ruby main.rb

Then: localhost:4567

Database

Scanty Redis will connect to Redis on localhost on the default port if you don't specify another location. To use something else, set REDIS_URL in your environment when running the app, i.e.:

$ REDIS_URL='redis://:secret@1.2.3.4:9000/3' ruby main.rb

This would connect to host 1.2.3.4 on port 9000, uses database number 3 (Redis databases are numbered, not named), using password “secret” (which is defined in the config file optionally passed to Redis when you start the server). Redis has no usernames so there in othing before the colon.

Redis creates databases automatically as needed, but if you want to introspect or clear the database, you can use the console and the DB constant:

$ irb -r main.rb 
irb(main):001:0> DB.keys('*')
=> ["Post:chrono", "Post:slug:first_post"]
irb(main):002:0> DB.flush_db
=> "OK"
irb(main):003:0> DB.keys('*')
=> []
