sinatra-rax

sinatra-rax is a minimal and modern Ruby/IRB console for Sinatra apps.

Goals

1. Call app.get '/' to trigger a request
2. Easily call Sinatra helpers, such as app.current_weather
3. Set ivars like app.set(name: 'bob', age: 25)
4. Use templates like app.erb :test (using name from above)
5. Set ivars like @name='mike', then app.erb :test, scope: self
6. Normal access to database calls, like Sponsor[2] to show a record
7. Call routes to show list sorted by route
8. Call props to show application settings

Install

Install via rubygems with:

gem install sinatra-rax

Or, add to your Gemfile using Bundler with:

bundle add sinatra-rax

This will add an executable in your path, which you can launch by typing rax.
