Sinatra has several configurable options you can set at the top of your application.

Default options, straight out of the code:

@default_options = {
        :run => true,
        :port => 4567,
        :env => :development,
        :root => root,
        :views => root + '/views',
        :public => root + '/public',
        :sessions => false,
        :logging => true,
        :raise_errors => false
}

Key options, and what they do:

• run - Should Sinatra auto-call run on itself with an at_exit handler. The idea is that you don’t have to put in a Sinatra.run anywhere in your application, it just happens automatically. I can’t think of a good reason to turn this off.
• env - Most of the time this is overridden by either the command line or the rackup file. A set in an application’s code will override any other previous setting, but this default isn’t used very often.
• root - Setting this has no effect, since it isn’t ever used anywhere in the code (currently…)
• views - Default views dir
• public - Default public dir (public means static files like css and js)
• sessions - Turn on sessions, uses a cookie store by default. I don’t know how to configure the store.
• logging - enables the Rack::CommonLogger middleware.

One at a time:

# Two arguments, key, then value
set :sessions, true
set :logging, false

All at once:

# One argument, a hash mapping key -> value
set :sessions => true,
    :logging => false,
    :views => 'path/to/views'
 
### For binary options, you can use enable:
enable :sessions, :logging
