StringControlCase - Erlang - e r l a n g : c o o k b o o k

Controlling Case

Problem

You need to convert a string to all uppercase or all lowercase.

Solution

1> string:to_upper("hello").
"HELLO"
2> string:to_lower("ERLANG").
"erlang"

For older solution, use httpd_util:to_upper() and httpd_util:to_lower()

Use httpd_util:to_upper or httpd_util:to_lower from the OTP httpd_util module. (Yes, I know that these would make more sense in the string module!)

Discussion

The httpd_util module contains a dog's breakfast of functionality that probably belong in other modules, but that have not been added due to backwards-compatibility concerns.
