Module: BigBand::ConfigFile

Defined in:
lib/big_band/config_file.rb

Overview

Using YAML config files. Config files are expected to represent hashes. When parsing such a config file it will use set to store that value, ignoring those directly defined in the app (not those defined by the class it inherits from, i.e. Sinatra::Base or BigBand).

Example:

class MyApp << BigBand
  set :foo, "bar"
  config_file "settings.yml"                 # general settings
  config_file "#{environment}.settings.yml"  # environment specific settings
  foo # => "bar"
end

Now you could write in your settings.yml:

---
server: [thin, webrick] # use only thin or webrick for #run!
public: /var/www        # load public files from /var/www
port:   8080            # run on port 8080
foo: baz
database:
  adapter: sqlite

In you development.settings.yml:

database:
  db_file: development.db
