6 Tk::Pod::FindPods - find Pods installed on the current system
7
9 use Tk::Pod::FindPods;
10
11 my $o = Tk::Pod::FindPods->new;
12 $pods = $o->pod_find(-categorized => 1, -usecache => 1);
13
15 pod_find
16 The pod_find method scans the current system for available Pod
17 documentation. The keys of the returned hash reference are the names of
18 the modules or Pods ("::" substituted by "/" --- this makes it easier
19 for Tk::Pod::Tree, as the separator may only be of one character). The
20 values are the corresponding filenames.
21
22 If "-categorized" is specified, then the returned hash has an extra
23 level with four categories: perl (for core language documentation),
24 pragma (for pragma documentation like var or strict), mod (core or CPAN
25 modules), and script (perl scripts with embedded Pod documentation).
26 Otherwise, "-category" may be set to force the Pods into a category.
27
28 By default, @INC is scanned for Pods. This can be overwritten by the
29 "-directories" option (specify as an array reference).
30
31 If "-usecache" is specified, then the list of Pods is cached (see cache
32 directory). "-usecache" is disabled if "-categorized" is not set or
33 "-directories" is set.
34
35 WriteCache
36 Write the Pod cache. The cache is written to the cache directory. The
37 file name is constructed from the perl version, operation system and
38 user id.
39
40 LoadCache()
41 Load the Pod cache, if possible.
42
43 Cache directory
44 By default the cache file is written to the directory ~/.tkpod_cache
45 (Unix systems), or the data directory as determined by File::HomeDir
46 (Windows, MacOSX). If everything fails, then the temporary directory
47 (/tmp or the OS equivalent) is used.
48
49 If necessary, then the last path component will be created (that is,
50 .tkpod_cache will be created if the directory does not exist).
51
52 To use another cache directory set the environment variable
53 "TKPODCACHE".
54
56 TKPODCACHE
57 Use a custom cache file instead of a file in the cache directory.
58 The following placeholders are recognized:
59
60 %v The perl version.
61
62 %o The OS (technically correct: the archname, which can include
63 tokens like "64int" or "thread").
64
65 %u The user id.
66
67 Example for using /some/other/directory for the cache file
68 location:
69
70 TKPODCACHE=/some/other/directory/pods_%v_%o_%u; export TKPODCACHE
71
72 or
73
74 setenv TKPODCACHE /some/other/directory/pods_%v_%o_%u
75
76 depending on your shell (sh-like or csh-like).
77
79 Tk::Tree.
