Re: Testing Edges

Params::Validate

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.

Dragonchild, I've been tinkering with it for a while, but don't seem to be having much luck with positional arguments as opposed to named ones. Named parameters seem to be working fine, I just don't seem to do anything, but check for existence of positional arguments. Just prior to the 'Dependancies' section on the documentation of the module it says.... `or this for positional parameters: validate_pos( @_, { type => SCALAR }, { type => ARRAYREF, optional => + 1 } ); By default, parameters are assumed to be mandatory unless specified as + optional.` [download] However, if I enter something like this... `#!/usr/bin/perl #use strict; use warnings; use Params::Validate; sub func1 { validate_pos( @_, { type => SCALAR} ); print "hi fluffy\n"; } func1("test");` [download] I get the following... `Argument "SCALAR" isn't numeric in subroutine entry at ./a.pl line 8. Parameter #1 ("test") to main::func1 was a 'scalar', which is not one +of the allowed types: at ./a.pl line 8 main::func1(3) called at ./a.pl line 13` [download] Any ideas why this is so? Ideas....?

You need to `use Params::Validate qw(:types);` [download] to get the constants used for type checking (the SCALAR in your example). Params::Validate docs - Espen	[reply] [d/l]
