Slength
returns the length of user supplied strings
I wrote Slength while working on my SQL Final project--you see, in an SQL database when you want to store a string of text in a field you have to declare the field's type as a varchar and give it a maximum length; I wrote slength to help me figure out how long I would need to set any given varchar field.
Slength was originally written in Perl, then rewritten in Python, and is now currently developed in Ruby.
