new

 my $client = PkgConfig::LibPkgConf::Client->new(%opts);
 my $client = PkgConfig::LibPkgConf::Client->new(\%opts);

Creates an instance of PkgConfig::LibPkgConf::Client. Possible options include:

path

The search path to look for ".pc" files. This may be specified either as a string with the appropriate path separator character, or as a list reference. This will override the "pkgconf" compiled in defaults and the environment variables for "PKG_CONFIG_PATH" or "PKG_CONFIG_LIBDIR".

filter_lib_dirs

List of directories to filter for libraries. This overrides the "pkgconf" compiled in default and environment variable for "PKG_CONFIG_SYSTEM_LIBRARY_PATH".

filter_include_dirs

List of directories to filter for include. This overrides the "pkgconf" compiled in default and environment variable for "PKG_CONFIG_SYSTEM_INCLUDE_PATH".

environment variables honored:

PKG_CONFIG_PATH

PKG_CONFIG_LIBDIR

PKG_CONFIG_SYSTEM_LIBRARY_PATH

PKG_CONFIG_SYSTEM_INCLUDE_PATH

PKG_CONFIG_ALLOW_SYSTEM_CFLAGS

PKG_CONFIG_ALLOW_SYSTEM_LIBS

path

 my @path = $client->path;

The search path to look for ".pc" files.

filter_lib_dirs

 my @dirs = $client->filter_lib_dirs;

List of directories to filter for libraries.

filter_include_dirs

 my @dirs = $client->filter_include_dirs;

List of directories to filter for includes.

sysroot_dir

 my $dir = $client->sysroot_dir;
 $client->sysroot_dir($dir);

Get or set the sysroot directory.

buildroot_dir

 my $dir = $client->buildroot_dir;
 $client->buildroot_dir($dir);

Get or set the buildroot directory.

maxdepth

 my $int = $client->maxdepth;
 $client->maxdepth($int);

Get or set the maximum dependency depth. This is 2000 by default.

env

 my $client->env;

This method loads settings for the client object from the environment using the standard "pkg-config" or "pkgconf" environment variables. It honors the following list of environment variables:

PKG_CONFIG_LOG

find

 my $pkg = $client->find($package_name);

Searches the <.pc> file for the package with the given $package_name. If found returns an instance of PkgConfig::LibPkgConf::Package. If not found returns "undef".

package_from_file

 my $pkg = $client->package_from_file($filename);

Load the specific <.pc> file.

scan_all

 $client->scan_all(sub {
   my($client, $package) = @_;
   ...
   return $bool;
 });

Iterates through all packages and calls the given subroutine reference for each package. $package isa PkgConfig::LibPkgConf::Package. The scan will continue so long as a non true value is returned (as $bool).

global

 $client->global($key => $value);
 my $value = $client->global($key);

Define or get the global variable.

error

 my $client->error($message);

Called when "libpkgconf" comes across a non-fatal error. By default the error is simply displayed as a warning using Carp. The intention of this method is if you want to override that behavior, you will subclass PkgConfig::LibPkgConf::Client and implement your own version of the "error" method.

audit_set_log

 $client->audit_set_log($filename, $mode);

Opens a file with the C "fopen" style $mode, and uses it for the audit log. The file is managed entirely by the client class and will be closed when the object falls out of scope. Examples:

 $client->audit_set_log("audit.log", "a"); # append to existing file
 $client->audit_set_log("audit2.log", "w"); # new or replace file
