NAME

Path::Trim - Makes paths compact

VERSION

This document describes Path::Trim version 0.0.1

SYNOPSIS

    use Path::Trim;

    my $path = 'a/b/../.././c/d';
    my $pt = Path::Trim->new();
    $pt->set_directory_separator('/');
    $trimmed_path = $pt->trim_path($path);

DESCRIPTION

Trims paths containing redundant current directory and parent directory entries.

For example:

    a/b/../.././c/d

is equivalent to:

    c/d

INTERFACE

new()

Returns an object of Path::Trim.

get_current_directory()

Returns the current directory representation.

Example:

    .

Defaults to . if not set with set_current_directory().

set_current_directory( current_directory )

Sets the current directory representation to the value of current_directory.

get_parent_directory()

Returns the parent directory representation.

Example:

    ..

Defaults to .. if not set with set_parent_directory().

set_parent_directory( parent_directory )

Sets the parent directory representation to the value of parent_directory.

get_directory_separator()

Returns the directory separator, if it has already been set with set_directory_separator().

set_directory_separator( directory_separator )

Sets the directory separator to the value of directory_separator.

trim_path( path )

Accepts a path (without volume) and returns the trimmed version. It assumes that a directory separator has already been set with set_directory_separator().

This is different from Cwd's abs_path() in that it does not have any filesystem ties.

DEPENDENCIES
