INTRODUCTION

This Module prevents field machine name from ending (_) underscore. For example, when you have brackets at the end of a label, e.g., "Address (2)", you end up with a trailing "_" character — field_address_2_.

Perhaps, you simply want to have good machine name of field, especially when it is ending with underscore or having two/more underscore and it has been truncated than you must use this module.
