Re: Params::Validate or Attribute::Params::Validate?

Note that Attribute::Params::Validate ships with Params::Validate.

So far, I've never needed to use the handlers form; Params::Validate has been perfectly adequate for my needs. However, I've found that not everybody likes Params::Validate, and I've had cases of people choosing not to use my CPAN modules owing to dependency on P::V. This inspired me to come up with Module::Optional including Params::Validate::Dummy, which allows people to still use code with calls to validate(), validate_pos() etc. without installing P::V.

Not all of my CPAN modules that use Params::Validate have been changed to use Module::Optionsl yet, but this is something I intend to incorporate on their next release.

I'm curious -- do you know why some people are so averse to Params::Validate as to avoid modules that depend on it? Do they think it doesn't work, or is cripplingly slow? Do they just avoid all XS? It doesn't use source filters or have exotic dependencies; reviews on CPAN ratings are good; there's nothing damning in rt.cpan.org; one Perlmonks node is the only bad I can find about it.	[reply]

In Regexp::NamedCaptures, I wrote this snippet so that P::V would be used if it was available and dummied up into place if it wasn't. I have half a mind to make that become a P::V::Fake and just include that with the distribution tarballs of my modules. My Build.PL recommends P::V and my Makefile.PL is silent on the matter. `BEGIN { eval { require Params::Validate; Params::Validate->import( 'validate_pos', 'SCALAR', 'UNDEF', 'CODEREF' ); }; if ( $@ ) { eval( 'sub validate_pos (\@@) { @{$_[0]} }' . 'sub SCALAR () { 0 }' . 'sub UNDEF () { 0 }' . 'sub CODEREF () { 0 }' ); } }` [download]	[reply] [d/l]
