Pod::Find(3p)    Perl Programmers Reference Guide   Pod::Find(3p)

       Pod::Find - find POD documents in directory trees

         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" );

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

         use Pod::Find qw(pod_find);

       "pod_find( { %opts } , @directories )"

       The function pod_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 name MyMod-
       ule, whereas $HOME/perl5lib/Myclass/Subclass.pm would be
       Myclass::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 directo-
       ries. This usually indicates duplicate occurrences of mod-
       ules in the @INC search path.

       OPTIONS The first argument for pod_find may be a hash ref-
       erence 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 do not
           match the current Perl interpreter's version id, sup-
           pressing site_perl as a module hierarchy name etc.

       "-script => 1"
           Search for PODs in the current Perl interpreter's
           installation scriptdir. This is taken from the local
           Config module.

       "-inc => 1"
           Search for PODs in the current Perl interpreter's @INC
           paths. This automatically considers paths specified in
           the "PERL5LIB" environment as this is prepended to
           @INC by the Perl interpreter itself.

       "simplify_name( $str )"

       The function simplify_name is equivalent to basename, 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.


       "-inc => 1"
           Search @INC for the pod and also the "scriptdir"
           defined in the Config 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

       A subdirectory pod/ 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.
