Module::Install::Can(3User Contributed Perl DocumentatiModule::Install::Can(3)NAMEModule::Install::Can - Utility functions for capability detection
DESCRIPTION
"Module::Install::Can" contains a number of functions for authors to
use when creating customised smarter installers. The functions simplify
standard tests so that you can express your dependencies and conditions
much more simply, and make your installer much easier to maintain.
COMMANDS
can_use
can_use('Module::Name');
can_use('Module::Name', 1.23);
The "can_use" function tests the ability to load a specific named
module. Currently it will also actually load the module in the process,
although this may change in the future.
Takes an optional second param of a version number. The currently
installed version of the module will be tested to make sure it is equal
to or greater than the specified version.
Returns true if the module can be loaded, or false (in both scalar or
list context) if not.
can_run
can_run('cvs');
The "can_run" function tests the ability to run a named command or
program on the local system.
Returns true if so, or false (both in scalar and list context) if not.
can_cc
can_cc();
The "can_cc" function test the ability to locate a C compiler on the
local system. Returns true if the C compiler can be found, or false
(both in scalar and list context) if not.
TO DO
Currently, the use of a "can_foo" command in a single problem domain
(for example "can_use") results in the inclusion of additional
functionality from different problem domains (for example "can_run").
This module should ultimately be broken up, and the individual
functions redestributed to different domain-specific extensions.
