# CPAN::Meta::Check(3pm)

Verify requirements in a CPAN::Meta object

## NAME

CPAN::Meta::Check - Verify requirements in a CPAN::Meta object

## VERSION

version 0.018

## SYNOPSIS

```
 warn "$_\n" for verify_dependencies($meta, [qw/runtime build test/], 'requires');
```

## DESCRIPTION

This module verifies if requirements described in a CPAN::Meta object are present.

## FUNCTIONS

### check\_requirements($reqs, $type, $incdirs)

This function checks if all dependencies in `$reqs` (a CPAN::Meta::Requirements object) are met, taking into account that 'conflicts' dependencies have to be checked in reverse. It returns a hash with the modules as keys and any problems as values; the value for a successfully found module will be undef. Modules are searched for in `@$incdirs`, defaulting to `@INC`.

### verify\_dependencies($meta, $phases, $types, $incdirs)

Check all requirements in `$meta` for phases `$phases` and type `$type`. Modules are searched for in `@$incdirs`, defaulting to `@INC`. `$meta` should be a CPAN::Meta::Prereqs or CPAN::Meta object.

### requirements\_for($meta, $phases, $types)

**This function is deprecated and may be removed at some point in the future, please use CPAN::Meta::Prereqs-\>merged\_requirements instead.**

This function returns a unified CPAN::Meta::Requirements object for all `$type` requirements for `$phases`. `$phases` may be either one (scalar) value or an arrayref of valid values as defined by the CPAN::Meta spec. `$type` must be a relationship as defined by the same spec. `$meta` should be a CPAN::Meta::Prereqs or CPAN::Meta object.
