| Summary : Advanced operations on path variables
|
Description :
Env::Path presents an object-oriented interface to _path variables_,
defined as that subclass of _environment variables_ which name an ordered
list of filesystem elements separated by a platform-standard _separator_
(typically \':\' on UNIX and \';\' on Windows).
Of course, core Perl constructs such
$ENV{PATH} .= \":/usr/local/bin\";
will suffice for most uses. Env::Path is for the others; cases where you
need to insert or remove interior path entries, strip redundancies, operate
on a pathvar without having to know whether the current platform uses \":\"
or \";\", operate on a pathvar which may have a different name on different
platforms, etc.
The OO interface is slightly unusual in that the environment variable is
itself the object and the constructor is Env::Path->AUTOLOAD(); thus
Env::Path->MANPATH;
will bless $ENV{MANPATH} into its package while leaving it otherwise
unmodified (with the exception of possible autovivification). Unlike most
objects, this is a scalar and thus can have only one attribute; its value.
In other words, Env::Path simply defines a set of methods a path variable
may call on itself without changing the variable\'s value or other
semantics.
Also, while the object reference may be assigned and used in the normal
style
my $path = Env::Path->CLASSPATH;
$path->Append(\'/opt/foo/classes.jar\');
a shorthand is also available:
Env::Path->CLASSPATH;
CLASSPATH->Append(\'/opt/foo/classes.jar\');
I.e. the name of the path variable may be used as a proxy for its object
reference. This may be done at \'use\' time too:
use Env::Path qw(PATH CLASSPATH); # or qw(:all) to bless all EV\'s
CLASSPATH->Append(\'/opt/foo/classes.jar\');
The design is intended to make use of this module as lightweight as
possible. Rather than creating a new object to manage an environment
variable, the environment variable is provided a set of methods for
self-modification but is otherwise left undisturbed and can be used in all
normal ways.
