libdata-validate-perl - 0.09-1.1 main

Data::Validate collects common validation routines to make input validation,
and untainting easier and more readable. Most of the functions are not much
shorter than their direct perl equivalent (and are much longer in some
cases), but their names make it clear what you're trying to test for (e.g.
is_integer(), is_hex(), is_alphanumeric()...).
.
Almost all functions return an untainted value if the test passes, and undef
if it fails. This means that you should always check for a defined status
explicitly. Don't assume the return will be true. (e.g. is_integer(0))
