Objective

Simply Disply How to debug sinatra application with debugger or pry

especially, I would like to step in method debug like below

How to Use

# added to the Gemfilegroup:development,:testdogem'awesome_print'gem'racksh'gem'debugger'gem'pry'gem'pry-debugger'end

You can just use debugger, if you run it ruby my_app.rb

classMyApp < Sinatra::Baseenable:sessionsget'/'dodebuggersession[:user]='anonymouse'redirectto('/bar')end

visit at http://localhost:4567

You can use pry, if you run it rackup

classMyApp < Sinatra::Baseenable:sessionsget'/'dobinding.prysession[:user]='anonymouse'redirectto('/bar')end

in case to use the short cut of next contine step finish add pry config

#.pryrcPry.commands.alias_command'c','continue'Pry.commands.alias_command's','step'Pry.commands.alias_command'n','next'Pry.commands.alias_command'f','finish'

visit at http://localhost:9292

looks like

ruby my_app.rb

rackup

sinatra console
