NAME

Debian::Control::FromCPAN - fill debian/control from unpacked CPAN distribution

SYNOPSIS

     my $c = Debian::Control::FromCPAN->new();
     $c->discover_dependencies( { ... } );
     $c->prune_perl_deps;
 
     Debian::Control::FromCPAN inherits from L<Debian::Control>.
 
 

METHODS

discover_dependencies( [ { options hash } ] )
Discovers module dependencies and fills the debendency fields in debian/control accordingly.

Options:

apt_contents
An instance of Debian::AptContents to be used when locating to which package a required module belongs.
dir
The directory where the cpan distribution was unpacked.
intrusive
A flag indicating permission to use Module::Depends::Intrusive for discovering dependencies in case Module::Depends fails. Sinse this requires loading all Perl modules in the distribution (and running their BEGIN blocks (and the BEGIN blocks of their dependencies, recursively), it is recommended to use this only when dealing with trusted sources.
require_deps
If true, causes the method to die if some a package for some dependency cannot be found. Otherwise only a warning is issued.
verbose
wnpp_query
An instance of Debian::WNPP::Query to be used when checking for WNPP bugs of depeended upon packages.

Returns a list of module names for which no suitable Debian packages were found.
find_debs_for_modules dep hash[, APT contents[, verbose ]]
Scans the given hash of dependencies ( module => version ) and returns matching Debian package dependency specification (as an instance of Debian::Dependencies class) and a list of missing modules.
prune_simple_perl_dep
Input:
dependency object
shall be a simple dependency (no alternatives)
(optional) build dependency flag
true value indicates the dependency is a build-time one

The following checks are made
dependencies on "perl-modules"
These are replaced with "perl" as per Perl policy.
dependencies on "perl-base" and build-dependencies on "perl" or "perl-base"
These are removed, unless they specify a version greater than the one available in "oldstable" or the dependency relation is not ">=" or ">>".

Return value:
undef
if the dependency is redundant.
pruned dependency
otherwise. "perl-modules" replaced with "perl".
prune_perl_dep
Similar to ``prune_simple_perl_dep'', but supports alternative dependencies. If any of the alternatives is redundant, the whole dependency is considered redundant.
prune_perl_deps
Remove redundant (build-)dependencies on perl, perl-modules and perl-base.
