man Tk::Pod::FindPods () - find Pods installed on the current system
NAME
Tk::Pod::FindPods - find Pods installed on the current system
SYNOPSIS
use Tk::Pod::FindPods;
my $o = Tk::Pod::FindPods->new;
$pods = $o->pod_find(-categorized => 1, -usecache => 1);
DESCRIPTION
pod_find
The pod_find method scans the current system for available Pod documentation. The keys of the returned hash reference are the names of the modules or Pods (CW:: substituted by CW/ --- this makes it easier for Tk::Pod::Tree, as the separator may only be of one character). The values are the corresponding filenames.
If CW-categorized is specified, then the returned hash has an extra level with four categories: perl (for core language documentation), pragma (for pragma documentation like var or strict), mod (core or CPAN modules), and script (perl scripts with embedded Pod documentation). Otherwise, CW-category may be set to force the Pods into a category.
By default, CW@INC is scanned for Pods. This can be overwritten by the CW-directories option (specify as an array reference).
If CW-usecache is specified, then the list of Pods is cached in a temporary directory. CW-usecache is disabled if CW-categorized is not set or CW-directories is set.
WriteCache
Write the Pod cache. The cache is written to the temporary directory. The file name is constructed from the perl version, operation system and user id.
LoadCache()
Load the Pod cache, if possible.
ENVIRONMENT
- TKPODCACHE
- Path for the cache file. By default, the cache file is written to the temporary directory (/tmp or the OS equivalent). The following placeholders are recognized:
- %v
- The perl version.
- %o
- The OS (technically correct: the archname, which can include tokens like 64int or thread).
- %u
-
The user id.
Example for using /var/tmp instead of /tmp for the cache file
location (on many systems /var/tmp is persistent, unlike /tmp):
setenv TKPODCACHE /var/tmp/pods_%v_%o_%u
orTKPODCACHE=/var/tmp/pods_%v_%o_%u; export TKPODCACHE
depending on your shell.
