=head1 NAME
=head1 SYNOPSIS
-C<use File::Spec;>
+ use File::Spec;
+
+ $x=File::Spec->catfile('a', 'b', 'c');
+
+which returns 'a/b/c' under Unix. Or:
-C<$x=File::Spec-E<gt>catfile('a','b','c');>
+ use File::Spec::Functions;
-which returns 'a/b/c' under Unix.
+ $x = catfile('a', 'b', 'c');
=head1 DESCRIPTION
File::Spec::VMS
The module appropriate for the current OS is automatically loaded by
-File::Spec. Since some modules (like VMS) make use of OS specific
-facilities, it may not be possible to load all modules under all operating
-systems.
+File::Spec. Since some modules (like VMS) make use of facilities available
+only under that OS, it may not be possible to load all modules under all
+operating systems.
-Since File::Spec is object oriented, subroutines should not called directly,
+Since File::Spec is object oriented, subroutines should not be called directly,
as in:
File::Spec::catfile('a','b');
-
+
but rather as class methods:
File::Spec->catfile('a','b');
-For a reference of available functions, pleaes consult L<File::Spec::Unix>,
-which contains the entire set, and inherited by the modules for other
-platforms. For further information, please see L<File::Spec::Mac>,
-L<File::Spec::OS2>, L<File::Spec::Win32>, or L<File::Spec::VMS>.
+For simple uses, L<File::Spec::Functions> provides convenient functional
+forms of these methods.
+
+=head1 METHODS
+
+=over 2
+
+=item canonpath
+
+No physical check on the filesystem, but a logical cleanup of a
+path.
+
+ $cpath = File::Spec->canonpath( $path ) ;
+
+Note that this does *not* collapse F<x/../y> sections into F<y>. This
+is by design. If F</foo> on your system is a symlink to F</bar/baz>,
+then F</foo/../quux> is actually F</bar/quux>, not F</quux> as a naive
+F<../>-removal would give you. If you want to do this kind of
+processing, you probably want C<Cwd>'s C<realpath()> function to
+actually traverse the filesystem cleaning up paths like this.
+
+=item catdir
+
+Concatenate two or more directory names to form a complete path ending
+with a directory. But remove the trailing slash from the resulting
+string, because it doesn't look good, isn't necessary and confuses
+OS/2. Of course, if this is the root directory, don't cut off the
+trailing slash :-)
+
+ $path = File::Spec->catdir( @directories );
+
+=item catfile
+
+Concatenate one or more directory names and a filename to form a
+complete path ending with a filename
+
+ $path = File::Spec->catfile( @directories, $filename );
+
+=item curdir
+
+Returns a string representation of the current directory.
+
+ $curdir = File::Spec->curdir();
+
+=item devnull
+
+Returns a string representation of the null device.
+
+ $devnull = File::Spec->devnull();
+
+=item rootdir
+
+Returns a string representation of the root directory.
+
+ $rootdir = File::Spec->rootdir();
+
+=item tmpdir
+
+Returns a string representation of the first writable directory from a
+list of possible temporary directories. Returns the current directory
+if no writable temporary directories are found. The list of directories
+checked depends on the platform; e.g. File::Spec::Unix checks C<$ENV{TMPDIR}>
+(unless taint is on) and F</tmp>.
+
+ $tmpdir = File::Spec->tmpdir();
+
+=item updir
+
+Returns a string representation of the parent directory.
+
+ $updir = File::Spec->updir();
+
+=item no_upwards
+
+Given a list of file names, strip out those that refer to a parent
+directory. (Does not strip symlinks, only '.', '..', and equivalents.)
+
+ @paths = File::Spec->no_upwards( @paths );
+
+=item case_tolerant
+
+Returns a true or false value indicating, respectively, that alphabetic
+case is not or is significant when comparing file specifications.
+
+ $is_case_tolerant = File::Spec->case_tolerant();
+
+=item file_name_is_absolute
+
+Takes as its argument a path, and returns true if it is an absolute path.
+
+ $is_absolute = File::Spec->file_name_is_absolute( $path );
+
+This does not consult the local filesystem on Unix, Win32, OS/2, or
+Mac OS (Classic). It does consult the working environment for VMS
+(see L<File::Spec::VMS/file_name_is_absolute>).
+
+=item path
+
+Takes no argument. Returns the environment variable C<PATH> (or the local
+platform's equivalent) as a list.
+
+ @PATH = File::Spec->path();
+
+=item join
+
+join is the same as catfile.
+
+=item splitpath
+
+Splits a path in to volume, directory, and filename portions. On systems
+with no concept of volume, returns '' for volume.
+
+ ($volume,$directories,$file) = File::Spec->splitpath( $path );
+ ($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file );
+
+For systems with no syntax differentiating filenames from directories,
+assumes that the last file is a path unless C<$no_file> is true or a
+trailing separator or F</.> or F</..> is present. On Unix, this means that C<$no_file>
+true makes this return ( '', $path, '' ).
+
+The directory portion may or may not be returned with a trailing '/'.
+
+The results can be passed to L</catpath()> to get back a path equivalent to
+(usually identical to) the original path.
+
+=item splitdir
+
+The opposite of L</catdir()>.
+
+ @dirs = File::Spec->splitdir( $directories );
+
+C<$directories> must be only the directory portion of the path on systems
+that have the concept of a volume or that have path syntax that differentiates
+files from directories.
+
+Unlike just splitting the directories on the separator, empty
+directory names (C<''>) can be returned, because these are significant
+on some OSes.
+
+=item catpath()
+
+Takes volume, directory and file portions and returns an entire path. Under
+Unix, C<$volume> is ignored, and directory and file are concatenated. A '/' is
+inserted if need be. On other OSes, C<$volume> is significant.
+
+ $full_path = File::Spec->catpath( $volume, $directory, $file );
+
+=item abs2rel
+
+Takes a destination path and an optional base path returns a relative path
+from the base path to the destination path:
+
+ $rel_path = File::Spec->abs2rel( $path ) ;
+ $rel_path = File::Spec->abs2rel( $path, $base ) ;
+
+If C<$base> is not present or '', then L<cwd()|Cwd> is used. If C<$base> is
+relative, then it is converted to absolute form using
+L</rel2abs()>. This means that it is taken to be relative to
+L<cwd()|Cwd>.
+
+On systems with the concept of volume, if C<$path> and C<$base> appear to be
+on two different volumes, we will not attempt to resolve the two
+paths, and we will instead simply return C<$path>. Note that previous
+versions of this module ignored the volume of C<$base>, which resulted in
+garbage results part of the time.
+
+On systems that have a grammar that indicates filenames, this ignores the
+C<$base> filename as well. Otherwise all path components are assumed to be
+directories.
+
+If C<$path> is relative, it is converted to absolute form using L</rel2abs()>.
+This means that it is taken to be relative to L<cwd()|Cwd>.
+
+No checks against the filesystem are made. On VMS, there is
+interaction with the working environment, as logicals and
+macros are expanded.
+
+Based on code written by Shigio Yamaguchi.
+
+=item rel2abs()
+
+Converts a relative path to an absolute path.
+
+ $abs_path = File::Spec->rel2abs( $path ) ;
+ $abs_path = File::Spec->rel2abs( $path, $base ) ;
+
+If C<$base> is not present or '', then L<cwd()|Cwd> is used. If C<$base> is relative,
+then it is converted to absolute form using L</rel2abs()>. This means that it
+is taken to be relative to L<cwd()|Cwd>.
+
+On systems with the concept of volume, if C<$path> and C<$base> appear to be
+on two different volumes, we will not attempt to resolve the two
+paths, and we will instead simply return C<$path>. Note that previous
+versions of this module ignored the volume of C<$base>, which resulted in
+garbage results part of the time.
+
+On systems that have a grammar that indicates filenames, this ignores the
+C<$base> filename as well. Otherwise all path components are assumed to be
+directories.
+
+If C<$path> is absolute, it is cleaned up and returned using L</canonpath()>.
+
+No checks against the filesystem are made. On VMS, there is
+interaction with the working environment, as logicals and
+macros are expanded.
+
+Based on code written by Shigio Yamaguchi.
