~/.pry_history not read in when using Ruby version 2.2.1

[mecampbellsoup]

Using 2.1.4, you can see reverse history search works (note the bck prompt, indicated I'm in a reverse history search process):

matthewcampbell@Matthews-MacBook-Pro:~|
⇒  rbenv local 2.1.4
matthewcampbell@Matthews-MacBook-Pro:~|
⇒  pry
no awesome_print :(
input> matt.trips
bck:trips

Using 2.2.0, history/reverse search still functional:

matthewcampbell@Matthews-MacBook-Pro:~|
⇒  rbenv local 2.2.0
matthewcampbell@Matthews-MacBook-Pro:~|
⇒  pry
no awesome_print :(
input> Ticket.whaled.count
bck:Ticket

Now, using 2.2.1 and searching once again for the string "Ticket", history breaks:

matthewcampbell@Matthews-MacBook-Pro:~|
⇒  rbenv local 2.2.1
matthewcampbell@Matthews-MacBook-Pro:~|
⇒  pry
no awesome_print :(
input>
bck?Ticket

Hmm, can you elaborate ; or, have I misunderstood?

This works OK for me -- ruby 2.2.1 compiled against real readline (which IIRC is the rbenv default), not MacOS' "libedit".

$ pry -e east-coker

  --
  Now the light falls
  Across the open field, leaving the deep lane
  Shuttered with branches, dark in the afternoon,
  Where you lean against a bank while a van passes,
  And the deep lane insists on the direction
  Into the village, in the electric heat
  Hypnotised. In a warm haze the sultry light
  Is absorbed, not refracted, by grey stone.
  The dahlias sleep in the empty silence.
  Wait for the early owl.
                -- T.S Eliot

[2] pry(main)> hist # Show session history, then (via readline/CTRL-r) reverse-search through "full history" ; could be shown with "hist --all".
1: east-coker
(reverse-i-search)`DB': DB = Sequel.sqlite 'data.sqlite'
[3] pry(main)> Readline::HISTORY.count # Show full history is indeed loaded.
=> 4980
[4] pry(main)> RUBY_DESCRIPTION
=> "ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin12.0]"

In case it helps,

find ~/.rbenv/versions/2.2.1 -iname \*readline\*bundle\* -exec otool -L {} \;
/Users/testuser/.rbenv/versions/2.2.1/lib/ruby/2.2.0/x86_64-darwin12.0/readline.bundle:

Yea I'm working again now, not sure what was going on but probably an issue isolate to my environment/machine. Cheers @richardkmichael

[richardkmichael]

@mecampbellsoup No problem, I was investigating some other history related curiosities and decided to check this out too. Can you close this issue?

Thanks @richardkmichael for the command finding readline bundle. It helps me a lot. 😄
