NAME

Pod::Find - find POD documents in directory trees

SYNOPSIS

use Pod::Find qw(pod_find simplify_name);my %pods = pod_find({ -verbose => 1, -inc => 1 });foreach(keys %pods) {   print "found library POD `$pods{$_}' in $_\n";}print "podname=",simplify_name('a/b/c/mymodule.pod'),"\n";$location = pod_where( { -inc => 1 }, "Pod::Find" );

DESCRIPTION

NOTE: This module is considered legacy; modern Perl releases (5.31.1 and higher) are going to remove Pod-Parser from core and usePod::Simple for all things POD.

Pod::Find provides a set of functions to locate POD files. Note that no function is exported by default to avoid pollution of your namespace, so be sure to specify them in theuse statement if you need them:

use Pod::Find qw(pod_find);

From this version on the typical SCM (software configuration management) directories are ignored. These are: RCS, CVS, SCCS, .svn, .hg, .git, .sync

pod_find( { %opts } , @directories )

The functionpod_find searches for POD documents in a given set of files and/or directories. It returns a hash with the file names as keys and the POD name as value. The POD name is derived from the file name and its position in the directory tree.

E.g. when searching in$HOME/perl5lib, the file$HOME/perl5lib/MyModule.pm would get the POD nameMyModule, whereas$HOME/perl5lib/Myclass/Subclass.pm would beMyclass::Subclass. The name information can be used for POD translators.

Only text files containing at least one valid POD command are found.

A warning is printed if more than one POD file with the same POD name is found, e.g.CPAN.pm in different directories. This usually indicates duplicate occurrences of modules in the@INC search path.

OPTIONS The first argument forpod_find may be a hash reference with options. The rest are either directories that are searched recursively or files. The POD names of files are the plain basenames with any Perl-like extension (.pm, .pl, .pod) stripped.

-verbose => 1

Print progress information while scanning.

-perl => 1

Apply Perl-specific heuristics to find the correct PODs. This includes stripping Perl-like extensions, omitting subdirectories that are numeric but donot match the current Perl interpreter's version id, suppressingsite_perl as a module hierarchy name etc.

-script => 1

Search for PODs in the current Perl interpreter's installationscriptdir. This is taken from the localConfig module.

-inc => 1

Search for PODs in the current Perl interpreter's@INC paths. This automatically considers paths specified in thePERL5LIB environment as this is included in@INC by the Perl interpreter itself.

simplify_name( $str )

The functionsimplify_name is equivalent tobasename, but also strips Perl-like extensions (.pm, .pl, .pod) and extensions like.bat,.cmd on Win32 and OS/2, or.com on VMS, respectively.

pod_where( { %opts }, $pod )

Returns the location of a pod document given a search directory and a module (e.g.File::Find) or script (e.g.perldoc) name.

Options:

-inc => 1

Search @INC for the pod and also thescriptdir defined in theConfig module.

-dirs => [ $dir1, $dir2, ... ]

Reference to an array of search directories. These are searched in order before looking in@INC (if-inc). Current directory is used if none are specified.

-verbose => 1

List directories as they are searched

Returns the full path of the first occurrence to the file. Package names (eg 'A::B') are automatically converted to directory names in the selected directory. (eg on unix 'A::B' is converted to 'A/B'). Additionally, '.pm', '.pl' and '.pod' are appended to the search automatically if required.

A subdirectorypod/ is also checked if it exists in any of the given search directories. This ensures that e.g.perlfunc is found.

It is assumed that if a module name is supplied, that that name matches the file name. Pods are not opened to check for the 'NAME' entry.

A check is made to make sure that the file that is found does contain some pod documentation.

contains_pod( $file , $verbose )

Returns true if the supplied filename (not POD module) contains some pod information.
