This function makes sure that the string does not go over a specific given limit. It has three parameters. "limit" which is defaulted to 32 and controls how far to show the characters. "more_indicator" which defaults to "." and controls which character to use to indicate there are more. "indicator_length" which defaults to 3 and controls how many times to show the more indicator.

'hello'.limit_print
'hello'

'elephant'.limit_print(limit: 2)
'el...'

'elephant'.limit_print(limit: 2, indicator_length: 0)
'el'

'elephant'.limit_print(limit: 3, more_indicator: '_')
'ele___'

'elephant'.limit_print(limit: 4, more_indicator: '*', indicator_length: 2)
