modules
SYNOPSIS
use ExtUtils::Installed;
my ($inst) = ExtUtils::Installed->new();
my (@modules) = $inst->modules();
my (@missing) = $inst->validate("DBI");
my $all_files = $inst->files("DBI");
my $files_below_usr_local = $inst->files("DBI", "all", "/usr/local");
my $all_dirs = $inst->directories("DBI");
my $dirs_below_usr_local = $inst->directory_tree("DBI", "prog");
my $packlist = $inst->packlist("DBI");
DESCRIPTIONExtUtils::Installed provides a standard way to find out
what core and module files have been installed. It uses
the information stored in .packlist files created during
installation to provide this information. In addition it
provides facilities to classify the installed files and to
extract directory information from the .packlist files.
USAGE
The new() function searches for all the installed
.packlists on the system, and stores their contents. The
.packlists can be queried with the functions described
below.
FUNCTIONSnew()
This takes no parameters, and searches for all the
installed .packlists on the system. The packlists
are read using the ExtUtils::packlist module.
modules()
This returns a list of the names of all the installed
modules. The perl 'core' is given the special name
'Perl'.
files()
This takes one mandatory parameter, the name of a
module. It returns a list of all the filenames from
the package. To obtain a list of core perl files,
use the module name 'Perl'. Additional parameters
are allowed. The first is one of the strings "prog",
"man" or "all", to select either just program files,
just manual files or all files. The remaining
parameters are a list of directories. The filenames
returned will be restricted to those under the
specified directories.

This takes one mandatory parameter, the name of a
module. It returns a list of all the directories
from the package. Additional parameters are allowed.
The first is one of the strings "prog", "man" or
"all", to select either just program directories,
just manual directories or all directories. The
remaining parameters are a list of directories. The
directories returned will be restricted to those
under the specified directories. This method returns
only the leaf directories that contain files from the
specified module.
directory_tree()
This is identical in operation to directory(), except
that it includes all the intermediate directories
back up to the specified directories.
validate()
This takes one mandatory parameter, the name of a
module. It checks that all the files listed in the
modules .packlist actually exist, and returns a list
of any missing files. If an optional second argument
which evaluates to true is given any missing files
will be removed from the .packlist
packlist()
This returns the ExtUtils::Packlist object for the
specified module.
version()
This returns the version number for the specified
module.
EXAMPLE
See the example in the ExtUtils::Packlist manpage.
