How do we access/manipulate variable names which conflicts with byebug reserved keywords?

Question

How do we access those variable names which conflict with byebug reserved name?

(byebug) var local
h = {"hierarchyId"=>"59f0b029e4b037ef11a055f7", "level"=>2, ...
self =                   <div class="index_as_table"></div>

I want to access variable "h"

but typing h would show up the "help dialog box for byebug"

(byebug) h

Is there any way to access variables who conflicts with these reserved keyword names. like exclamation prefix in python's pdb? (!h didn't work for byebug)

Answer 1

You can surround it in parentheses:

[1, 4] in /Users/max/test.rb
   1: require 'byebug'
   2:
   3: byebug
=> 4: false
(byebug) (h = 1)
1
(byebug) (h)
1
(byebug)

Answer 2

You can use:

eval h
