String decrement

Ruby
1

Hello All,

It is possible to increment a string as follows:

irb(main):001:0> x = ‘a’
=> “a”
irb(main):002:0> x.succ
=> “b”
irb(main):003:0> x.next
=> “b”

Is there a method to decrement a string?

Thanks,
Darryl

Defining decrement behavior for strings is much more difficult than
you might expect. Can you define exact behavior?

Hello Matz,

This is quite an honor.

I was facing a minor problem using ruby for some data
collection by writing results to excel. I have since
solved this by offsetting my start column by one cell.

This eliminates my original need to decrement the column.

Have also learned that excel cells can be expressed numerically
as well.

Thanks,
Darryl
