Ruby - Ecosystem and Best Practices

You wrote this in your ~/.irbrc file:

IRB.conf[:SAVE_HISTORY] = '1000'

But IRB does not save history as expected. What is the problem?

AThe key <code>:SAVE_HISTORY</code> is invalid

BThe value should be an integer, not a string

CIRB does not support saving history

DYou must restart the computer for changes to apply

Step-by-Step Solution

Solution:

Step 1: Check the data type of the value
:SAVE_HISTORY expects an integer number, not a string.
Step 2: Identify the error cause
Using a string like '1000' causes IRB to ignore the setting, so history is not saved.
Final Answer:
The value should be an integer, not a string -> Option B
Quick Check:
Integer value needed for history count [OK]

Quick Trick: Use numbers, not strings, for numeric IRB config values [OK]
