NAME ^

File::Spec::Epoc - methods for Epoc file specs

SYNOPSIS ^

 require File::Spec::Epoc; # Done internally by File::Spec if needed

DESCRIPTION ^

See File::Spec::Unix for a documentation of the methods provided there. This package overrides the implementation of these methods, not the semantics.

This package is still work in progress ;-) o.flebbe@gmx.de

devnull

Returns a string representation of the null device.

tmpdir

Returns a string representation of a temporay directory:

path

Takes no argument, returns the environment variable PATH as an array. Since there is no search path supported, it returns undef, sorry.

canonpath()

No physical check on the filesystem, but a logical cleanup of a path. On UNIX eliminated successive slashes and successive "/.".

splitpath
    ($volume,$directories,$file) = File::Spec->splitpath( $path );
    ($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file );

Splits a path in to volume, directory, and filename portions. Assumes that the last file is a path unless the path ends in '\\', '\\.', '\\..' or $no_file is true. On Win32 this means that $no_file true makes this return ( $volume, $path, undef ).

Separators accepted are \ and /.

The results can be passed to "catpath" to get back a path equivalent to (usually identical to) the original path.

splitdir

The opposite of catdir().

    @dirs = File::Spec->splitdir( $directories );

$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, leading empty and trailing directory entries can be returned, because these are significant on some OSs. So,

    File::Spec->splitdir( "/a/b/c" );

Yields:

    ( '', 'a', 'b', '', 'c', '' )
catpath

Takes volume, directory and file portions and returns an entire path. Under Unix, $volume is ignored, and this is just like catfile(). On other OSs, the $volume become significant.

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( $destination ) ;
    $rel_path = File::Spec->abs2rel( $destination, $base ) ;

If $base is not present or '', then cwd() is used. If $base is relative, then it is converted to absolute form using "rel2abs()". This means that it is taken to be relative to cwd().

On systems with the concept of a volume, this assumes that both paths are on the $destination volume, and ignores the $base volume.

On systems that have a grammar that indicates filenames, this ignores the $base filename as well. Otherwise all path components are assumed to be directories.

If $path is relative, it is converted to absolute form using "rel2abs()". This means that it is taken to be relative to cwd().

Based on code written by Shigio Yamaguchi.

No checks against the filesystem are made.

rel2abs()

Converts a relative path to an absolute path.

    $abs_path = File::Spec->rel2abs( $destination ) ;
    $abs_path = File::Spec->rel2abs( $destination, $base ) ;

If $base is not present or '', then cwd() is used. If $base is relative, then it is converted to absolute form using "rel2abs()". This means that it is taken to be relative to cwd().

Assumes that both paths are on the $base volume, and ignores the $destination volume.

On systems that have a grammar that indicates filenames, this ignores the $base filename as well. Otherwise all path components are assumed to be directories.

If $path is absolute, it is cleaned up and returned using "canonpath()".

Based on code written by Shigio Yamaguchi.

No checks against the filesystem are made.
