File::Spec::VMS - methods for VMS file specs
require File::Spec::VMS; # Done internally by File::Spec if needed
See File::Spec::Unix for a documentation of the methods provided
there. This package overrides the implementation of these methods, not the
semantics.
The default behavior is to allow either VMS or Unix syntax on
input and to return VMS syntax on output unless Unix syntax has been
explicitly requested via the
"DECC$FILENAME_UNIX_REPORT" CRTL
feature.
- canonpath
(override)
- Removes redundant portions of file specifications and returns results in
native syntax unless Unix filename reporting has been enabled.
- catdir (override)
- Concatenates a list of file specifications, and returns the result as a
native directory specification unless the Unix filename reporting feature
has been enabled. No check is made for "impossible" cases (e.g.
elements other than the first being absolute filespecs).
- catfile
(override)
- Concatenates a list of directory specifications with a filename
specification to build a path.
- curdir (override)
- Returns a string representation of the current directory: '[]' or '.'
- devnull
(override)
- Returns a string representation of the null device: '_NLA0:' or
'/dev/null'
- rootdir
(override)
- Returns a string representation of the root directory: 'SYS$DISK:[000000]'
or '/'
- tmpdir (override)
- Returns a string representation of the first writable directory from the
following list or '' if none are writable:
/tmp if C<DECC$FILENAME_UNIX_REPORT> is enabled.
sys$scratch:
$ENV{TMPDIR}
If running under taint mode, and if
$ENV{TMPDIR} is tainted, it is not used.
- updir (override)
- Returns a string representation of the parent directory: '[-]' or
'..'
- case_tolerant
(override)
- VMS file specification syntax is case-tolerant.
- path (override)
- Translate logical name DCL$PATH as a searchlist, rather than trying to
"split" string value of
$ENV{'PATH'}.
- file_name_is_absolute
(override)
- Checks for VMS directory spec as well as Unix separators.
- splitpath
(override)
-
($volume,$directories,$file) = File::Spec->splitpath( $path );
($volume,$directories,$file) = File::Spec->splitpath( $path,
$no_file );
Passing a true value for $no_file
indicates that the path being split only contains directory components,
even on systems where you can usually (when not supporting a foreign
syntax) tell the difference between directories and files at a
glance.
- splitdir
(override)
- Split a directory specification into the components.
- catpath
(override)
- Construct a complete filespec.
- abs2rel
(override)
- Attempt to convert an absolute file specification to a relative
specification.
- rel2abs
(override)
- Return an absolute file specification from a relative one.
