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¶
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 the
use statement if you need them:
use Pod::Find qw(pod_find);
From this version on the typical SCM (software configuration management)
files/directories like RCS, CVS, SCCS, .svn are ignored.
"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
MyModule, 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 directories. This usually indicates duplicate
occurrences of modules in the
@INC search path.
OPTIONS The first argument for
pod_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 do not match the current Perl interpreter's version
id, suppressing 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 included in
@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.
Options:
- "-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 required.
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.
