It can be built up by adding more and more constraints, and it will reduce them to the simplest representation.</p> <p>Logically impossible constraints will be identified immediately by thrown exceptions.</p> <h1 id="METHODS">METHODS</h1> <h2 id="new">new</h2> <pre><code>my $req = CPAN::Meta::Requirements->new;</code></pre> <p>This returns a new CPAN::Meta::Requirements object. It takes an optional hash reference argument. Currently, only one key is supported:</p> <ul> <li><p><code>bad_version_hook</code> -- if provided, when a version cannot be parsed into a version object, this code reference will be called with the invalid version string as first argument, and the module name as second argument. It must return a valid version object.</p> </li> </ul> <p>All other keys are ignored.</p> <h2 id="add_minimum">add_minimum</h2> <pre><code>$req->add_minimum( $module => $version );</code></pre> <p>This adds a new minimum version requirement. If the new requirement is redundant to the existing specification, this has no effect.</p> <p>Minimum requirements are inclusive. <code>$version</code> is required, along with any greater version number.</p> <p>This method returns the requirements object.</p> <h2 id="add_maximum">add_maximum</h2> <pre><code>$req->add_maximum( $module => $version );</code></pre> <p>This adds a new maximum version requirement. If the new requirement is redundant to the existing specification, this has no effect.</p> <p>Maximum requirements are inclusive. No version strictly greater than the given version is allowed.</p> <p>This method returns the requirements object.</p> <h2 id="add_exclusion">add_exclusion</h2> <pre><code>$req->add_exclusion( $module => $version );</code></pre> <p>This adds a new excluded version. For example, you might use these three method calls:</p> <pre><code>$req->add_minimum( $module => '1.00' ); $req->add_maximum( $module => '1.82' ); $req->add_exclusion( $module => '1.75' );</code></pre> <p>Any version between 1.00 and 1.82 inclusive would be acceptable, except for 1.75.</p> <p>This method returns the requirements object.</p> <h2 id="exact_version">exact_version</h2> <pre><code>$req->exact_version( $module => $version );</code></pre> <p>This sets the version required for the given module to <i>exactly</i> the given version. No other version would be considered acceptable.</p> <p>This method returns the requirements object.</p> <h2 id="version_range_for_module">version_range_for_module</h2> <pre><code>$req->version_range_for_module( $another_req_object );</code></pre> <h2 id="add_requirements">add_requirements</h2> <pre><code>$req->add_requirements( $another_req_object );</code></pre> <p>This method adds all the requirements in the given CPAN::Meta::Requirements object to the requirements object on which it was called. If there are any conflicts, an exception is thrown.</p> <p>This method returns the requirements object.</p> <h2 id="accepts_module">accepts_module</h2> <pre><code>my $bool = $req->accepts_module($module => $version);</code></pre> <p>Given an module and version, this method returns true if the version specification for the module accepts the provided version. In other words, given:</p> <pre><code>Module => '>= 1.00, < 2.00'</code></pre> <p>We will accept 1.00 and 1.75 but not 0.50 or 2.00.</p> <p>For modules that do not appear in the requirements, this method will return true.</p> <h2 id="clear_requirement">clear_requirement</h2> <pre><code>$req->clear_requirement( $module );</code></pre> <p>This removes the requirement for a given module from the object.</p> <p>This method returns the requirements object.</p> <h2 id="requirements_for_module">requirements_for_module</h2> <pre><code>$req->requirements_for_module( $module );</code></pre> <p>This returns a string containing the version requirements for a given module in the format described in <a href="/pod/CPAN::Meta::Spec">CPAN::Meta::Spec</a> or undef if the given module has no requirements. This should only be used for informational purposes such as error messages and should not be interpreted or used for comparison (see <a href="#accepts_module">"accepts_module"</a> instead).</p> <h2 id="structured_requirements_for_module">structured_requirements_for_module</h2> <pre><code>$req->structured_requirements_for_module( $module );</code></pre> <p>This returns a data structure containing the version requirements for a given module or undef if the given module has no requirements. This should not be used for version checks (see <a href="#accepts_module">"accepts_module"</a> instead).</p> <p>Added in version 2.134.</p> <h2 id="required_modules">required_modules</h2> <p>This method returns a list of all the modules for which requirements have been specified.</p> <h2 id="clone">clone</h2> <pre><code>$req->clone;</code></pre> <p>This method returns a clone of the invocant. The clone and the original object can then be changed independent of one another.</p> <h2 id="is_simple">is_simple</h2> <p>This method returns true if and only if all requirements are inclusive minimums -- that is, if their string expression is just the version number.</p> <h2 id="is_finalized">is_finalized</h2> <p>This method returns true if the requirements have been finalized by having the <code>finalize</code> method called on them.</p> <h2 id="finalize">finalize</h2> <p>This method marks the requirements finalized. Subsequent attempts to change the requirements will be fatal, <i>if</i> they would result in a change. If they would not alter the requirements, they have no effect.</p> <p>If a finalized set of requirements is cloned, the cloned requirements are not also finalized.</p> <h2 id="as_string_hash">as_string_hash</h2> <p>This returns a reference to a hash describing the requirements using the strings in the <a href="/pod/CPAN::Meta::Spec">CPAN::Meta::Spec</a> specification.</p> <p>For example after the following program:</p> <pre><code>my $req = CPAN::Meta::Requirements->new; $req->add_minimum('CPAN::Meta::Requirements' => 0.102); $req->add_minimum('Library::Foo' => 1.208); $req->add_maximum('Library::Foo' => 2.602); $req->add_minimum('Module::Bar' => 'v1.2.3'); $req->add_exclusion('Module::Bar' => 'v1.2.8'); $req->exact_version('Xyzzy' => '6.01'); my $hashref = $req->as_string_hash;</code></pre> <p><code>$hashref</code> would contain:</p> <pre><code>{ 'CPAN::Meta::Requirements' => '0.102', 'Library::Foo' => '>= 1.208, <= 2.206', 'Module::Bar' => '>= v1.2.3, != v1.2.8', 'Xyzzy' => '== 6.01', }</code></pre> <h2 id="add_string_requirement">add_string_requirement</h2> <pre><code>$req->add_string_requirement('Library::Foo' => '>= 1.208, <= 2.206'); $req->add_string_requirement('Library::Foo' => v1.208);</code></pre> <p>This method parses the passed in string and adds the appropriate requirement for the given module. A version can be a Perl "v-string". It understands version ranges as described in the <a href="/pod/CPAN::Meta::Spec#Version-Ranges">"Version Ranges" in CPAN::Meta::Spec</a>. For example:</p> <dl> <dt id="1.3"><a id="1"></a><a id="pod1.3"></a>1.3</dt> <dd> </dd> <dt id=">=-1.3"><a id="pod-1.3"></a>>= 1.3</dt> <dd> </dd> <dt id="<=-1.3"><a id="pod-1.31"></a><= 1.3</dt> <dd> </dd> <dt id="==-1.3"><a id="pod-1.32"></a>== 1.3</dt> <dd> </dd> <dt id="!=-1.3"><a id="pod-1.33"></a>!= 1.3</dt> <dd> </dd> <dt id=">-1.3"><a id="pod1.31"></a>> 1.3</dt> <dd> </dd> <dt id="<-1.3"><a id="pod1.32"></a>< 1.3</dt> <dd> </dd> <dt id=">=-1.3,-!=-1.5,-<=-2.0"><a id="pod-1.3-1.5-2.0"></a>>= 1.3, != 1.5, <= 2.0</dt> <dd> <p>A version number without an operator is equivalent to specifying a minimum (<code>>=</code>). Extra whitespace is allowed.</p> </dd> </dl> <h2 id="from_string_hash">from_string_hash</h2> <pre><code>my $req = CPAN::Meta::Requirements->from_string_hash( \%hash ); my $req = CPAN::Meta::Requirements->from_string_hash( \%hash, \%opts );</code></pre> <p>This is an alternate constructor for a CPAN::Meta::Requirements object. It takes a hash of module names and version requirement strings and returns a new CPAN::Meta::Requirements object. As with add_string_requirement, a version can be a Perl "v-string". Optionally, you can supply a hash-reference of options, exactly as with the <a href="#new">"new"</a> method.</p> <h1 id="SUPPORT">SUPPORT</h1> <h2 id="Bugs-/-Feature-Requests"><a id="Bugs"></a><a id="Bugs-Feature-Requests"></a>Bugs / Feature Requests</h2> <p>Please report any bugs or feature requests through the issue tracker at <a href="https://github.com/Perl-Toolchain-Gang/CPAN-Meta-Requirements/issues">https://github.com/Perl-Toolchain-Gang/CPAN-Meta-Requirements/issues</a>.
