Saying require 'pry';binding.pry is too much to type every time you want to drop into Pry from a script.

Here are some solutions.

TODO soon

Use binding_of_caller to get it to something like: load'pry/here'

Vim mappings

" Add the pry debug line with \bp (or <Space>bp, if you did: map <Space> <Leader> )
map <Leader>bp orequire'pry';binding.pry<esc>:w<cr>
" Alias for one-handed operation:
map <Leader><Leader>p <Leader>bp
" …also, Insert Mode as bpry<space>
iabbr bpry require'pry';binding.pry

" Keep pry from annoyingly hanging around when using, e.g. pry-rescue/minitest
map <f3> :wa<cr>:call system('kill-pry-rescue')<cr>

" Nab lines from ~/.pry_history (respects "count")
nmap <Leader>pry :<c-u>let pc = (v:count1 ? v:count1 : 1)<cr>:read !tail -<c-r>=pc<cr> ~/.pry_history<cr>:.-<c-r>=pc-1<cr>:norm <c-r>=pc<cr>==<cr>
nmap <Leader>ph <Leader>pry
" ↑ thanks to Houl, ZyX-i, and paradigm of #vim for all dogpiling on this one.

nmap <Leader>rib of = File.open ENV['HOME']+'/ribson', 'w'; set_trace_func -> *args { f.puts [args, args[4].send(:local_variables) ].inspect }<esc>:w<cr>

Shell Script + eval ?

echo 'echo "require \"pry\"; binding.pry"' > ~/bin/ph; chmod +x ~/bin/ph

Then you're supposed to be able to ph, and it works except for a critical detail: when you do that the "binding" is wrong. Any ideas?

Global method

def dbg(b_ing = binding)
  require 'pry'
  b_ing.pry
end

• (+) It spares you the require part
  • (-) But not the binding, which is the way you most likely would use it
• (-) Has to be defined on a per-project basis, though it:
  • (+) Lets you use any editor
  • (+) Lets you use any CLI command (like cucumber, rails, etc...)
