Pod::MinimumVersion - Perl version for POD directives used
use Pod::MinimumVersion; my $pmv = Pod::MinimumVersion->new (filename => '/some/foo.pl'); print $pmv->minimum_version,"\n"; print $pmv->reports;
Pod::MinimumVersion parses the POD in a Perl script, module, or document, and reports what version of Perl is required to process the directives in it with
The following POD features are identified.
5.005: new L<display text|target> style display part
5.6.0: new C<< foo >> etc double-angles
5.8.0: new L<http://some.where.com> URLs. (Before 5.8 the "/" is a "section" separator, giving very poor output.)
5.8.0: new E<apos>, E<sol>, E<verbar> chars. (Documented in 5.6.0, but pod2man doesn't recognise them until 5.8.)
=encodingcommand. (Documented in 5.8.0, but
pod2mandoesn't recognise it until 5.10.)
5.12.0: new L<display text|http://some.where.com> URL with text. (Before 5.12 the combination of display part and URL was explicitly disallowed by perlpodspec.)
POD syntax errors are quietly ignored currently. The intention is only to check what
pod2man would act on but it's probably a good idea to use
J<< >> for
Pod::MultiLang is recognised and is allowed for any Perl, including with double-angles. The assumption is that if you're writing that then you'll first crunch with the
Pod::MultiLang tools, so it's not important what
pod2man thinks of it.
$pmv = Pod::MinimumVersion->new (key => value, ...)
Create and return a new
Pod::MinimumVersionobject which will analyze a document. The document is supplied as one of
filehandle => $fh, string => 'something', filename => '/my/dir/foo.pod',
filenamecan be supplied too to give a name in the reports. The handle or string is what's actually read.
above_versionoption lets you set a Perl version of you have or are targeting, so reports are only about features above that level.
above_version => '5.006',
$version = $pmv->minimum_version ()
$report = $pmv->minimum_report ()
Return the minimum Perl required for the document in
@reports = $pmv->reports ()
Return a list of
Pod::MinimumVersion::Reportobjects concerning the document in
These multiple reports let you identify multiple places that a particular Perl is required. With the
above_versionoption the reports are only about things higher than that.
minimum_reportare simply the highest Perl among these multiple reports.
Pod::MinimumVersion::Report object holds a location within a document and a reason that a particular Perl is needed at that point. The hash fields are
filename string linenum integer, with 1 for the first line version version.pm object why string
$str = $report->as_string
Return a formatted string for the report. Currently this is in GNU file:line style, simply
<filename>:<linenum>: <version> due to <why>
