scandeps.pl - Scan file prerequisites
% scandeps.pl *.pm # Print PREREQ_PM section for *.pm
% scandeps.pl -e 'STRING' # Scan an one-liner
% scandeps.pl -B *.pm # Include core modules
% scandeps.pl -V *.pm # Show autoload/shared/data files
scandeps.pl is a simple-minded utility that prints out the
PREREQ_PM section needed by modules.
If you have CPANPLUS installed, modules that are part of an
earlier module's distribution with be denoted with S; modules
without a distribution name on CPAN are marked with ?.
Also, if the -B option is specified, module belongs to a perl
distribution on CPAN (and thus uninstallable by CPAN.pm or
CPANPLUS.pm) are marked with C.
Finally, modules that has loadable shared object files (usually
needing a compiler to install) are marked with X; with the
-V flag, those files (and all other files found) will be listed
before the main output. Additionally, all module files that the
scanned code depends on but were not found (and thus not scanned
recursively) are listed. These may include genuinely missing
modules or false positives. That means, modules your code does
not depend on (on this particular platform) but that were picked
up by the heuristic anyway.
Scan STRING as a string containing perl code.
Compiles the code and inspects its %INC, in addition to static scanning.
Executes the code and inspects its %INC, in addition to static scanning.
Include core modules in the output and the recursive search list.
Verbose mode: Output all files found during the process; show dependencies between modules and availability.
Additionally, warns of any missing dependencies. If you find missing dependencies that aren't really dependencies, you have probably found false positives.
