NAME

6       Pod::Find - find POD documents in directory trees
7

SYNOPSIS

9         use Pod::Find qw(pod_find simplify_name);
10         my %pods = pod_find({ -verbose => 1, -inc => 1 });
11         foreach(keys %pods) {
12            print "found library POD `$pods{$_}' in $_\n";
13         }
14
15         print "podname=",simplify_name('a/b/c/mymodule.pod'),"\n";
16
17         $location = pod_where( { -inc => 1 }, "Pod::Find" );

DESCRIPTION

20       Pod::Find provides a set of functions to locate POD files.  Note that
21       no function is exported by default to avoid pollution of your names‐
22       pace, so be sure to specify them in the use statement if you need them:
23
24         use Pod::Find qw(pod_find);
25
26       From this version on the typical SCM (software configuration manage‐
27       ment) files/directories like RCS, CVS, SCCS, .svn are ignored.
28
29       "pod_find( { %opts } , @directories )"
30
31       The function pod_find searches for POD documents in a given set of
32       files and/or directories. It returns a hash with the file names as keys
33       and the POD name as value. The POD name is derived from the file name
34       and its position in the directory tree.
35
36       E.g. when searching in $HOME/perl5lib, the file $HOME/perl5lib/MyMod‐
37       ule.pm would get the POD name MyModule, whereas
38       $HOME/perl5lib/Myclass/Subclass.pm would be Myclass::Subclass. The name
39       information can be used for POD translators.
40
41       Only text files containing at least one valid POD command are found.
42
43       A warning is printed if more than one POD file with the same POD name
44       is found, e.g. CPAN.pm in different directories. This usually indicates
45       duplicate occurrences of modules in the @INC search path.
46
47       OPTIONS The first argument for pod_find may be a hash reference with
48       options. The rest are either directories that are searched recursively
49       or files.  The POD names of files are the plain basenames with any
50       Perl-like extension (.pm, .pl, .pod) stripped.
51
52       "-verbose => 1"
53           Print progress information while scanning.
54
55       "-perl => 1"
56           Apply Perl-specific heuristics to find the correct PODs. This
57           includes stripping Perl-like extensions, omitting subdirectories
58           that are numeric but do not match the current Perl interpreter's
59           version id, suppressing site_perl as a module hierarchy name etc.
60
61       "-script => 1"
62           Search for PODs in the current Perl interpreter's installation
63           scriptdir. This is taken from the local Config module.
64
65       "-inc => 1"
66           Search for PODs in the current Perl interpreter's @INC paths. This
67           automatically considers paths specified in the "PERL5LIB" environ‐
68           ment as this is prepended to @INC by the Perl interpreter itself.
69
70       "simplify_name( $str )"
71
72       The function simplify_name is equivalent to basename, but also strips
73       Perl-like extensions (.pm, .pl, .pod) and extensions like .bat, .cmd on
74       Win32 and OS/2, or .com on VMS, respectively.
75
76       "pod_where( { %opts }, $pod )"
77
78       Returns the location of a pod document given a search directory and a
79       module (e.g. "File::Find") or script (e.g. "perldoc") name.
80
81       Options:
82
83       "-inc => 1"
84           Search @INC for the pod and also the "scriptdir" defined in the
85           Config module.
86
87       "-dirs => [ $dir1, $dir2, ... ]"
88           Reference to an array of search directories. These are searched in
89           order before looking in @INC (if -inc). Current directory is used
90           if none are specified.
91
92       "-verbose => 1"
93           List directories as they are searched
94
95       Returns the full path of the first occurrence to the file.  Package
96       names (eg 'A::B') are automatically converted to directory names in the
97       selected directory. (eg on unix 'A::B' is converted to 'A/B'). Addi‐
98       tionally, '.pm', '.pl' and '.pod' are appended to the search automati‐
99       cally if required.
100
101       A subdirectory pod/ is also checked if it exists in any of the given
102       search directories. This ensures that e.g. perlfunc is found.
103
104       It is assumed that if a module name is supplied, that that name matches
105       the file name. Pods are not opened to check for the 'NAME' entry.
106
107       A check is made to make sure that the file that is found does contain
108       some pod documentation.
109
110       "contains_pod( $file , $verbose )"
111
112       Returns true if the supplied filename (not POD module) contains some
113       pod information.
