.IX Header "METHODS"
.IP "discover_dependencies( [ { options hash } ] )" 4
.IX Item "discover_dependencies( [ { options hash } ] )"
Discovers module dependencies and fills the dependency fields in
\&\fIdebian/control\fR accordingly.
.Sp
Options:
.RS 4
.IP "apt_contents" 4
.IX Item "apt_contents"
An instance of Debian::AptContents to be used when locating to which package
a required module belongs.
.IP "dir" 4
.IX Item "dir"
The directory where the cpan distribution was unpacked.
.IP "intrusive" 4
.IX Item "intrusive"
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 \s-1BEGIN\s0 blocks
(and the \s-1BEGIN\s0 blocks of their dependencies, recursively), it is recommended to
use this only when dealing with trusted sources.
.IP "require_deps" 4
.IX Item "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.
.IP "verbose" 4
.IX Item "verbose"
.PD 0
.IP "wnpp_query" 4
.IX Item "wnpp_query"
.PD
An instance of Debian::WNPP::Query to be used when checking for \s-1WNPP\s0 bugs of
depended upon packages.
.RE
.RS 4
.Sp
Returns a list of module names for which no suitable Debian packages were
found.
.RE
.IP "find_debs_for_modules \fIdep hash\fR[, \s-1APT\s0 contents[, verbose ]]" 4
.IX Item "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.
.Sp
Perl core is searched first, then installed packages, then the \s-1APT\s0 contents.
.IP "prune_simple_perl_dep" 4
.IX Item "prune_simple_perl_dep"
Input:
.RS 4
.IP "dependency object" 4
.IX Item "dependency object"
shall be a simple dependency (no alternatives)
.IP "(optional) build dependency flag" 4
.IX Item "(optional) build dependency flag"
true value indicates the dependency is a build-time one
.RE
.RS 4
.Sp
The following checks are made
.ie n .IP "dependencies on ""perl\-modules""" 4
.el .IP "dependencies on \f(CWperl\-modules\fR" 4
.IX Item "dependencies on perl-modules"
These are replaced with \f(CW\*(C`perl\*(C'\fR as per Perl policy.
.ie n .IP "dependencies on ""perl\-base"" and build-dependencies on ""perl"" or ""perl\-base""" 4
.el .IP "dependencies on \f(CWperl\-base\fR and build-dependencies on \f(CWperl\fR or \f(CWperl\-base\fR" 4
.IX Item "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 \f(CW\*(C`oldstable\*(C'\fR or the dependency relation is not \f(CW\*(C`>=\*(C'\fR or \f(CW\*(C`>>\*(C'\fR.
.RE
.RS 4
.Sp
Return value:
.IP "undef" 4
.IX Item "undef"
if the dependency is redundant.
.IP "pruned dependency" 4
.IX Item "pruned dependency"
otherwise. \f(CW\*(C`perl\-modules\*(C'\fR replaced with \f(CW\*(C`perl\*(C'\fR.
.RE
.RS 4
.RE
.IP "prune_perl_dep" 4
.IX Item "prune_perl_dep"
Similar to \*(L"prune_simple_perl_dep\*(R", but supports alternative dependencies.
If any of the alternatives is redundant, the whole dependency is considered
redundant.
.IP "prune_perl_deps" 4
.IX Item "prune_perl_deps"
Remove redundant (build\-)dependencies on perl, perl-modules and perl-base.
.SH "CLASS METHODS"
.IX Header "CLASS METHODS"
.IP "module_name_to_pkg_name" 4
.IX Item "module_name_to_pkg_name"
Receives a perl module name like \f(CW\*(C`Foo::Bar\*(C'\fR and returns a suitable Debian
package name for it, like \f(CW\*(C`libfoo\-bar\-perl\*(C'\fR.
