# rax - Half rat-pack, half tux... a minimal and modern Sinatra console in IRB
#
# Author: Steve Shreeve (steve.shreeve@gmail.com)
#   Date: Jan 15, 2023
# ==============================================================================
# NOTE: Here are the 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`w
# 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
# ==============================================================================
