NAME
ExtUtils::Installed - Inventory management of installed 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");
DESCRIPTION
ExtUtils::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. Where it
searches by default is determined by the settings found in %Config::Config, and what the
value is of the PERL5LIB environment variable.
FUNCTIONS
new()
This takes optional named parameters. Without parameters, this searches for all the
installed .packlists on the system using information from %Config::Config and the
default module search paths @INC. The packlists are read using the ExtUtils::Packlist
module.
If the named parameter "config_override" is specified, it should be a reference to a
hash which contains all information usually found in %Config::Config. For example, you
can obtain the configuration information for a separate perl installation and pass
that in.
my $yoda_cfg = get_fake_config('yoda');
my $yoda_inst = ExtUtils::Installed->new(config_override=>$yoda_cfg);
Similarly, the parameter "inc_override" may be a reference to an array which is used
in place of the default module search paths from @INC.
use Config;
my @dirs = split(/\Q$Config{path_sep}\E/, $ENV{PERL5LIB});
my $p5libs = ExtUtils::Installed->new(inc_override=>\@dirs);
The parameter c<extra_libs> can be used to specify additional paths to search for
installed modules. For instance
my $installed = ExtUtils::Installed->new(extra_libs=>["/my/lib/path"]);
This should only be necessary if "/my/lib/path" is not in PERL5LIB.
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", "doc" 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.
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", "doc" 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 directories(), 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 ExtUtils::Packlist.
