9 % scandeps.pl *.pm # Print PREREQ_PM section for *.pm
10 % scandeps.pl -e 'STRING' # Scan an one-liner
11 % scandeps.pl -B *.pm # Include core modules
12 % scandeps.pl -V *.pm # Show autoload/shared/data files
13 % scandeps.pl -R *.pm # Don't recurse
14 % scandeps.pl -C CACHEFILE # use CACHEFILE to cache dependencies
15
17 scandeps.pl is a simple-minded utility that prints out the "PREREQ_PM"
18 section needed by modules.
19
20 If the option "-T" is specified and you have CPANPLUS installed,
21 modules that are part of an earlier module's distribution with be
22 denoted with "S"; modules without a distribution name on CPAN are
23 marked with "?".
24
25 Also, if the "-B" option is specified, module belongs to a perl
26 distribution on CPAN (and thus uninstallable by "CPAN.pm" or
27 "CPANPLUS.pm") are marked with "C".
28
29 Finally, modules that has loadable shared object files (usually needing
30 a compiler to install) are marked with "X"; with the "-V" flag, those
31 files (and all other files found) will be listed before the main
32 output. Additionally, all module files that the scanned code depends on
33 but were not found (and thus not scanned recursively) are listed. These
34 may include genuinely missing modules or false positives. That means,
35 modules your code does not depend on (on this particular platform) but
36 that were picked up by the heuristic anyway.
37
39 -e, --eval=STRING
40 Scan STRING as a string containing perl code.
41
42 -c, --compile
43 Compiles the code and inspects its %INC, in addition to static
44 scanning.
45
46 -x, --execute
47 Executes the code and inspects its %INC, in addition to static
48 scanning. You may use --xargs to specify @ARGV when executing the
49 code.
50
51 --xargs=STRING
52 If -x is given, splits the "STRING" using the function "shellwords"
53 from Text::ParseWords and passes the result as @ARGV when executing
54 the code.
55
56 -B, --bundle
57 Include core modules in the output and the recursive search list.
58
59 -R, --no-recurse
60 Only show dependencies found in the files listed and do not
61 recurse.
62
63 -V, --verbose
64 Verbose mode: Output all files found during the process; show
65 dependencies between modules and availability.
66
67 Additionally, warns of any missing dependencies. If you find
68 missing dependencies that aren't really dependencies, you have
69 probably found false positives.
70
71 -C, --cachedeps=CACHEFILE
72 Use CACHEFILE to speed up the scanning process by caching
73 dependencies. Creates CACHEFILE if it does not exist yet.
74
75 -T, --modtree
76 Retrieves module information from CPAN if you have CPANPLUS
77 installed.
