SCANDEPS(1)                          User Contributed Perl Documentation                         SCANDEPS(1)



NAME
       scandeps.pl - Scan file prerequisites

SYNOPSIS
           % 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 -R *.pm       # Don't recurse
           % scandeps.pl -C CACHEFILE  # use CACHEFILE to cache dependencies

DESCRIPTION
       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.

OPTIONS
       -e STRING
           Scan STRING as a string containing perl code.

       -c  Compiles the code and inspects its %INC, in addition to static scanning.

       -x  Executes the code and inspects its %INC, in addition to static scanning.

       -B  Include core modules in the output and the recursive search list.

       -R  Only show dependencies found in the files listed and do not recurse.

       -V  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.

       -C CACHEFILE
           Use CACHEFILE to speed up the scanning process by caching dependencies.  Creates CACHEFILE if it
           does not exist yet.
