# Using these pry gems
# Essentials
# gem "pry"
# gem "pry-rails"
# gem "pry-byebug"
# gem "pry-doc"
# gem "pry-rescue"

# If you like this one:
# gem "pry-state"

# Probably not so necessary
# gem "pry-toys"

# Do not use pry-stack_explorer as it conflicts with pry-byebug

# Pry::Commands.block_command "noconflict", "Rename step to sstep and next to nnext" do
#   Pry::Commands.rename_command("nnext", "next")
#   Pry::Commands.rename_command("bbreak", "break")
# end

# Pry::Commands.block_command "unnoconflict", "Revert to normal next and break" do
#   Pry::Commands.rename_command("next", "nnext")
#   Pry::Commands.rename_command("break", "bbreak")
# end
