Rescue unhandled exceptions functionality about pry-byebug HOT 7 OPEN

Yes, pry-byebug is incompatible with pry-stack_explorer or any plugins making use of it. byebug already provides the functionality pry-rescue offer so the solution I'd like for this issue is to bring that functionality through byebug.

I'll leave this open as a remainder.

Hi.
Does byebug already have "Rescue unhandled exceptions functionality"? How can I make it work?
Also, byebug's frame output format is pretty different from that of pry-rescue's show-stack. show-stack lists all frames up to the top, so it's more informative. Is is possible to implement it in byebug?

[5] pry(main)> show-stack

Showing all accessible frames in stack (6 in total):
--
=> #0  ccc <Object#ccc()>
   #1 [block]   block in ccc <Object#ccc()>
   #2 [method]  ccc <Object#ccc()>
   #3 [method]  bbb <Object#bbb()>
   #4 [method]  aaa <Object#aaa()>
   #5 [main]    <main>

[6] pry(main)> frame
#0  ccc <Object#ccc()>
      in main @ hoge.rb:23

Hi @aoyama-val, thanks for your comments.

byebug does have the "rescue unhandled exceptions" functionality. You have to enable the post_mortem option through set post_mortem. But, there are some issues with it in rubies >= 2.2.4, see deivid-rodriguez/byebug#165. I'm not sure whether it's totally broken or not, you can try.

Regard the way of showing the stack, you're mistaking the frame command with the bt (or backtrace or where command). That's the correct way of showing the full stack.

Hi @deivid-rodriguez, thanks for the information.

I gavepost_mortem a quick try with Ruby 2.3.0, and I didn't notice any failure. So it seems not broken totally.

byebug has bt/backtrace/where commands, but pry-byebug does NOT. So we cannot use them in a pry session. Am I missing something?

You're welcome! I'm glad the good old post-mortem mode is still usable :)

Regarding your second comment, yes, you're right. pry-byebug needs a command to show the full stack. I thought you were aware of it since you mentioned byebug's frame command in your first message (which exists too). Now I see you meant pry-byebug's frame command.

In any case, feel free to work on adding this new show-stack command!

Any progress on bringing post-mortem functionality through to pry-byebug from byebug?

Not really, sorry.
