NAME

Path::Mapper - Map a virtual path to an actual one

VERSION

version 0.012

SYNOPSIS

    my $mapper = Path::Mapper->new( base => '../' )
    $mapper->map( a/b => /apple )

    $mapper->dir( /a/b/xyzzy/ ) # /apple/xyzzy
    $mapper->dir( /a/bxyzzy/ ) # ../a/bxyzzy

DESCRIPTION

Path::Mapper will map a virtual path to an actual one, doing a substitution based on the deepest common directory

Think of it as doing something like symbolic link resolution (though not exactly)

USAGE

Path::Mapper->new( [ base => <base> ] )

Create a new Path::Mapper object using <base> as the 'root' directory (by default, everything is mapped to be under that directory)

$mapper->base( <base> )

Change the base directory for $mapper to <base>

$mapper->map( <virtual> => <actual> )

Set up a map from <virtual> and anything under (e.g. <virtual>/*) to map to the <actual> prefix instead of the usual base

$mapper->map( <path> )

Return a 2-element list containing the actual base for this path and the path remainder. You probably don't want/need to use this method

$mapper->dir( <path> )

Map the virtual <path> to an actual one and return the result as a Path::Class::Dir object

$mapper->file( <path> )

Map the virtual <path> to an actual one and return the result as a Path::Class::File object

$mapper->path( <path> )

Map the virtual <path> to an actual one and return the result as a Path::Abstract object
