NAME

6       Module::Refresh - Refresh %INC files when updated on disk
7

SYNOPSIS

9           # During each request, call this once to refresh changed modules:
10
11           Module::Refresh->refresh;
12
13           # Each night at midnight, you automatically download the latest
14           # Acme::Current from CPAN.  Use this snippet to make your running
15           # program pick it up off disk:
16
17           $refresher->refresh_module('Acme/Current.pm');

DESCRIPTION

20       This module is a generalization of the functionality provided by
21       Apache::StatINC and Apache::Reload.  It's designed to make it easy to
22       do simple iterative development when working in a persistent
23       environment.
24
25       It does not require mod_perl.
26
27   new
28       Initialize the module refresher.
29
30   refresh
31       Refresh all modules that have mtimes on disk newer than the newest ones
32       we've got.  Calls "new" to initialize the cache if it had not yet been
33       called.
34
35       Specifically, it will renew any module that was loaded before the
36       previous call to "refresh" (or "new") and has changed on disk since
37       then.  If a module was both loaded for the first time and changed on
38       disk between the previous call and this one, it will not be reloaded by
39       this call (or any future one); you will need to update the modification
40       time again (by using the Unix "touch" command or making a change to it)
41       in order for it to be reloaded.
42
43   refresh_module_if_modified $module
44       If $module has been modified on disk, refresh it. Otherwise, do nothing
45
46   refresh_module $module
47       Refresh a module.  It doesn't matter if it's already up to date.  Just
48       do it.
49
50       Note that it only accepts module names like "Foo/Bar.pm", not
51       "Foo::Bar".
52
53   unload_module $module
54       Remove a module from %INC, and remove all subroutines defined in it.
55
56   mtime $file
57       Get the last modified time of $file in seconds since the epoch;
58
59   update_cache $file
60       Updates the cached "last modified" time for $file.
61
62   unload_subs $file
63       Wipe out subs defined in $file.
64

BUGS

66       When we walk the symbol table to whack reloaded subroutines, we don't
67       have a good way to invalidate the symbol table properly, so we mess up
68       on things like global variables that were previously set.
