CPAN::Reporter::PrereqCheck - Modulino for prerequisite tests


version 1.2018


  require CPAN::Reporter::PrereqCheck;
  my $prereq_check = $INC{'CPAN/Reporter/'};
  my $result = qx/$perl $prereq_check < $prereq_file/;


This modulino determines whether a list of prerequisite modules are available and, if so, their version number. It is designed to be run as a script in order to provide this information from the perspective of a subprocess, just like CPAN::Reporter's invocation of "perl Makefile.PL" and so on.

It reads a module name and prerequisite string pair from each line of input and prints out the module name, 0 or 1 depending on whether the prerequisite is satisfied, and the installed module version. If the module is not available, it will print "n/a" for the version. If the module is available but can't be loaded, it will print "broken" for the version. Modules without a version will be treated as being of version "0".

No user serviceable parts are inside. This modulino is packaged for internal use by CPAN::Reporter.


Please report any bugs or feature using the CPAN Request Tracker. Bugs can be submitted through the web interface at <>
