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

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

Discovers module dependencies and fills the dependency fields in debian/control accordingly.


An instance of Debian::AptContents to be used when locating to which package a required module belongs.
An instance of Dpkg::Index to be used when checking whether the locally available package is the required version. For example:

    my $available = Dpkg::Index->new(type => CTRL_INFO_PKG);
The directory where the cpan distribution was unpacked.
A flag indicating permission to use Module::Depends::Intrusive for discovering dependencies in case Module::Depends fails. Since 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.
If true, causes the method to die if some a package for some dependency cannot be found. Otherwise only a warning is issued.
An instance of Debian::WNPP::Query to be used when checking for WNPP bugs of depended upon packages.

Returns a list of module names for which no suitable Debian packages were found.

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.

Installed packages and perl core are searched first, then the APT contents.

If a Dpkg::Index object is passed, also check the available package version.

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

These are replaced with "perl" as per Perl policy.
These are removed, unless they specify a version greater than the one available in "oldstable" or the dependency relation is not ">=" or ">>".

Return value:

if the dependency is redundant.
otherwise. "perl-modules*" and "libperl*" replaced with "perl".
Similar to "prune_simple_perl_dep", but supports alternative dependencies. If any of the alternatives is redundant, the whole dependency is considered redundant.
Remove redundant (build-)dependencies on perl, libperl, perl-modules and perl-base.

Receives a perl module name like "Foo::Bar" and returns a suitable Debian package name for it, like "libfoo-bar-perl".
