NAME

6       Module::Extract::Use - Pull out the modules a module explicitly uses
7

SYNOPSIS

9               use Module::Extract::Use;
10
11               my $extor = Module::Extract::Use->new;
12
13               my @modules = $extor->get_modules( $file );
14               if( $extor->error ) { ... }
15
16               my $details = $extor->get_modules_with_details( $file );
17               foreach my $detail ( @$details ) {
18                       printf "%s %s imports %s\n",
19                               $detail->module, $detail->version,
20                               join ' ', @{ $detail->imports }
21                       }

DESCRIPTION

24       Extract the names of the modules used in a file using a static
25       analysis. Since this module does not run code, it cannot find dynamic
26       uses of modules, such as "eval "require $class"". It only reports
27       modules that the file loads directly. Modules loaded with "parent" or
28       "base", for instance, will will be in the import list for those pragmas
29       but won't have separate entries in the data this module returns.
30
31       new Makes an object. The object doesn't do anything just yet, but you
32           need it to call the methods.
33
34       init
35           Set up the object. You shouldn't need to call this yourself.
36
37       get_modules( FILE )
38           Returns a list of namespaces explicity use-d in FILE. Returns undef
39           if the file does not exist or if it can't parse the file.
40
41           Each used namespace is only in the list even if it is used multiple
42           times in the file. The order of the list does not correspond to
43           anything so don't use the order to infer anything.
44
45       get_modules_with_details( FILE )
46           Returns a list of hash references, one reference for each namespace
47           explicitly use-d in FILE. Each reference has keys for:
48
49                   namespace - the namespace, always defined
50                   version   - defined if a module version was specified
51                   imports   - an array reference to the import list
52                   pragma    - true if the module thinks this namespace is a pragma
53
54           Each used namespace is only in the list even if it is used multiple
55           times in the file. The order of the list does not correspond to
56           anything so don't use the order to infer anything.
57
58       error
59           Return the error from the last call to "get_modules".

TO DO

62       ·   Make it recursive, so it scans the source for any module that it
63           finds.
