I'm using a PERL cgi script that uses rrdtool to make graphs. I can't get the syntax correct to use a degree sign (alt+0176 like this °) and also using a variable.
If I use single quotes, I can't call the variable. If I use double quotes, there is an extra symbol (Â) before the ° which goes... (2 Replies)

Hi... I have a question regarding the split function in PERL.

Hi all, I'm going bonkers trying to figure something out that is probably simple for most of you. I have a choice between getting therapy for this or coming here to ask for help. I chose the latter. :D
What I'm trying to do is perform a split on a line but only one split. For example, let's... (4 Replies)
Hi expert,
As we know in regular expression, means neither a nor b.
Now the question is how to consider <ab> as a whole part or somehow a single char. Something like which is meaning neither ( nor a nor b nor ).
Or do we have another way for this?
The real requirement is as below: ... (2 Replies)

Attribute::Params::Validate(3pm) User Contributed Perl Documentation Attribute::Params::Validate(3pm)NAME
Attribute::Params::Validate - support for attributes
SYNOPSIS
use Attribute::Params::Validate qw(:all);
# takes named params (hash or hashref)
# foo is mandatory, bar is optional
sub foo : Validate( foo => 1, bar => 0 )
{
...
}
# takes positional params
# first two are mandatory, third is optional
sub bar : ValidatePos( 1, 1, 0 )
{
...
}
# for some reason Perl insists that the entire attribute be on one line
sub foo2 : Validate( foo => { type => ARRAYREF }, bar => { can => [ 'print', 'flush', 'frobnicate' ] }, baz => { type => SCALAR, callbacks => { 'numbers only' => sub { shift() =~ /^d+$/ }, 'less than 90' => sub { shift() < 90 } } } )
{
...
}
# note that this is marked as a method. This is very important!
sub baz : Validate( foo => { type => ARRAYREF }, bar => { isa => 'Frobnicator' } ) method
{
...
}
DESCRIPTION
The Attribute::Params::Validate module allows you to validate method or function call parameters just like Params::Validate does. However,
this module allows you to specify your validation spec as an attribute, rather than by calling the "validate" routine.
Please see Params::Validate for more information on how you can specify what validation is performed.
EXPORT
This module exports everything that Params::Validate does except for the "validate" and "validate_pos" subroutines.
ATTRIBUTES
o Validate
This attribute corresponds to the "validate" subroutine in Params::Validate.
o ValidatePos
This attribute corresponds to the "validate_pos" subroutine in Params::Validate.
OO
If you are using this module to mark methods for validation, as opposed to subroutines, it is crucial that you mark these methods with the
":method" attribute, as well as the "Validate" or "ValidatePos" attribute.
If you do not do this, then the object or class used in the method call will be passed to the validation routines, which is probably not
what you want.
CAVEATS
You must put all the arguments to the "Validate" or "ValidatePos" attribute on a single line, or Perl will complain.
