NAME
App::Info::Lib::OSSPUUID - Information about the OSSP UUID library SYNOPSIS
use App::Info::Lib::OSSPUUID; my $uuid = App::Info::Lib::OSSPUUID->new; if ($uuid->installed) { print "App name: ", $uuid->name, " "; print "Version: ", $uuid->version, " "; print "Bin dir: ", $uuid->bin_dir, " "; } else { print "Expat is not installed. :-( "; } DESCRIPTION
App::Info::Lib::OSSPUUID supplies information about the OSSP UUID library installed on the local system. It implements all of the methods defined by App::Info::Lib. Methods that trigger events will trigger them only the first time they're called (See App::Info for documentation on handling events). To start over (after, say, someone has installed the OSSP UUID library) construct a new App::Info::Lib::OSSPUUID object to aggregate new meta data. Some of the methods trigger the same events. This is due to cross-calling of shared subroutines. However, any one event should be triggered no more than once. For example, although the info event "Executing `uuid-config --version`" is documented for the methods "name()" "version()", "major_version()", "minor_version()", and "patch_version()", rest assured that it will only be triggered once, by whichever of those four methods is called first. INTERFACE
Constructor new my $expat = App::Info::Lib::OSSPUUID->new(@params); Returns an App::Info::Lib::OSSPUUID object. See App::Info for a complete description of argument parameters. When called, "new()" searches all of the paths returned by the "search_lib_dirs()" method for one of the files returned by the "search_lib_names()" method. If any of is found, then the OSSP UUID library is assumed to be installed. Otherwise, most of the object methods will return "undef". Events: info Looking for uuid-config confirm Path to uuid-config? unknown Path to uuid-config? Class Method key_name my $key_name = App::Info::Lib::OSSPUUID->key_name; Returns the unique key name that describes this class. The value returned is the string "OSSP UUID". Object Methods installed print "UUID is ", ($uuid->installed ? '' : 'not '), "installed. "; Returns true if the OSSP UUID library is installed, and false if it is not. App::Info::Lib::OSSPUUID determines whether the library is installed based on the presence or absence on the file system of the "uuid-config" application, searched for when "new()" constructed the object. If the OSSP UUID library does not appear to be installed, then most of the other object methods will return empty values. name my $name = $uuid->name; Returns the name of the library. App::Info::Lib::OSSPUUID parses the name from the system call "`uuid-config --version`". Events: info Executing `uuid-config --version` error Failed to find OSSP UUID version with `uuid-config --version` Unable to parse name from string Unable to parse version from string Failed to parse OSSP UUID version parts from string unknown Enter a valid OSSP UUID version number version my $version = $uuid->version; Returns the OSSP UUID version number. App::Info::Lib::OSSPUUID parses the version number from the system call "`uuid-config --version`". Events: info Executing `uuid-config --version` error Failed to find OSSP UUID version with `uuid-config --version` Unable to parse name from string Unable to parse version from string Failed to parse OSSP UUID version parts from string unknown Enter a valid OSSP UUID version number major version my $major_version = $uuid->major_version; Returns the OSSP UUID library major version number. App::Info::Lib::OSSPUUID parses the major version number from the system call "`uuid-config --version`". For example, if "version()" returns "1.3.0", then this method returns "1". Events: info Executing `uuid-config --version` error Failed to find OSSP UUID version with `uuid-config --version` Unable to parse name from string Unable to parse version from string Failed to parse OSSP UUID version parts from string unknown Enter a valid OSSP UUID major version number minor version my $minor_version = $uuid->minor_version; Returns the OSSP UUID library minor version number. App::Info::Lib::OSSPUUID parses the minor version number from the system call "`uuid-config --version`". For example, if "version()" returns "1.3.0", then this method returns "3". Events: info Executing `uuid-config --version` error Failed to find OSSP UUID version with `uuid-config --version` Unable to parse name from string Unable to parse version from string Failed to parse OSSP UUID version parts from string unknown Enter a valid OSSP UUID minor version number patch version my $patch_version = $uuid->patch_version; Returns the OSSP UUID library patch version number. App::Info::Lib::OSSPUUID parses the patch version number from the system call "`uuid-config --version`". For example, if "version()" returns "1.3.0", then this method returns "0". Events: info Executing `uuid-config --version` error Failed to find OSSP UUID version with `uuid-config --version` Unable to parse name from string Unable to parse version from string Failed to parse OSSP UUID version parts from string unknown Enter a valid OSSP UUID minor version number executable my $exe = $uuid->executable; Returns the full path to the OSSP UUID executable, which is named uuid. This method does not use the executable names returned by "search_exe_names()"; those executable names are used to search for uuid-config only (in "new()"). When it called, "executable()" checks for an executable named uuid in the directory returned by "bin_dir()". Note that "executable()" is simply an alias for "uuid()". Events: info Looking for uuid executable confirm Path to uuid executable? unknown Path to uuid executable? bin_dir my $bin_dir = $uuid->bin_dir; Returns the OSSP UUID binary directory path. App::Info::Lib::OSSPUUID gathers the path from the system call "`uuid-config --bindir`". Events: info Executing `uuid-config --bindir` error Cannot find bin directory unknown Enter a valid OSSP UUID bin directory inc_dir my $inc_dir = $uuid->inc_dir; Returns the OSSP UUID include directory path. App::Info::Lib::OSSPUUID gathers the path from the system call "`uuid-config --includedir`". Events: info Executing `uuid-config --includedir` error Cannot find include directory unknown Enter a valid OSSP UUID include directory lib_dir my $lib_dir = $uuid->lib_dir; Returns the OSSP UUID library directory path. App::Info::Lib::OSSPUUID gathers the path from the system call "`uuid-config --libdir`". Events: info Executing `uuid-config --libdir` error Cannot find library directory unknown Enter a valid OSSP UUID library directory so_lib_dir my $so_lib_dir = $uuid->so_lib_dir; Returns the OSSP UUID shared object library directory path. This is actually just an alias for "lib_dir()". Events: info Executing `uuid-config --libdir` error Cannot find library directory unknown Enter a valid OSSP UUID library directory cflags my $configure = $uuid->cflags; Returns the C flags used when compiling the OSSP UUID library. App::Info::Lib::OSSPUUID gathers the configure data from the system call "`uuid-config --cflags`". Events: info Executing `uuid-config --configure` error Cannot find configure information unknown Enter OSSP UUID configuration options ldflags my $configure = $uuid->ldflags; Returns the LD flags used when compiling the OSSP UUID library. App::Info::Lib::OSSPUUID gathers the configure data from the system call "`uuid-config --ldflags`". Events: info Executing `uuid-config --configure` error Cannot find configure information unknown Enter OSSP UUID configuration options perl_module my $bool = $uuid->perl_module; Return true if "OSSP::uuid" is installed and can be loaded, and false if not. "OSSP::uuid" must be able to be loaded by the currently running instance of the Perl interpreter. Events: info Loading OSSP::uuid home_url my $home_url = $uuid->home_url; Returns the OSSP UUID home page URL. download_url my $download_url = $uuid->download_url; Returns the OSSP UUID download URL. search_exe_names my @search_exe_names = $app->search_exe_names; Returns a list of possible names for uuid-config executable. By default, only uuid-config is returned (or uuid-config.exe on Win32). Note that this method is not used to search for the OSSP UUID server executable, only uuid-config. search_bin_dirs my @search_bin_dirs = $app->search_bin_dirs; Returns a list of possible directories in which to search an executable. Used by the "new()" constructor to find an executable to execute and collect application info. The found directory will also be returned by the "bin_dir" method. The list of directories by default consists of the path as defined by "File::Spec->path", as well as the following directories: /usr/local/bin /usr/local/sbin /usr/bin /usr/sbin /bin C:Program Filesuidin Other Executable Methods These methods function just like the "executable()" method, except that they return different executables. OSSP UUID comes with a fair number of them; we provide these methods to provide a path to a subset of them. Each method, when called, checks for an executable in the directory returned by "bin_dir()". The name of the executable must be one of the names returned by the corresponding "search_*_names" method. The available executable methods are: uuid uuid_config And the corresponding search names methods are: search_postgres_names search_createdb_names Events: info Looking for executable confirm Path to executable? unknown Path to executable?
