.IX Title "File::Spec::VMS 3"
.TH File::Spec::VMS 3 "2002-11-24" "perl v5.8.0" "Perl Programmers Reference Guide"
.SH "NAME"
File::Spec::VMS \- methods for VMS file specs
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\& require File::Spec::VMS; # Done internally by File::Spec if needed
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
See File::Spec::Unix for a documentation of the methods provided
there. This package overrides the implementation of these methods, not
the semantics.
.IP "eliminate_macros" 4
.IX Item "eliminate_macros"
Expands MM[\s-1KS\s0]/Make macros in a text string, using the contents of
identically named elements of \f(CW%$self\fR, and returns the result
as a file specification in Unix syntax.
.IP "fixpath" 4
.IX Item "fixpath"
Catchall routine to clean up problem MM[\s-1SK\s0]/Make macros.  Expands macros
in any directory specification, in order to avoid juxtaposing two
VMS-syntax directories when MM[\s-1SK\s0] is run.  Also expands expressions which
are all macro, so that we can tell how long the expansion is, and avoid
overrunning \s-1DCL\s0's command buffer when MM[\s-1KS\s0] is running.
.Sp
If optional second argument has a \s-1TRUE\s0 value, then the return string is
a VMS-syntax directory specification, if it is \s-1FALSE\s0, the return string
is a VMS-syntax file specification, and if it is not specified, \fIfixpath()\fR
checks to see whether it matches the name of a directory in the current
default directory, and returns a directory or file specification accordingly.
.Sh "Methods always loaded"
.IX Subsection "Methods always loaded"
.IP "canonpath (override)" 4
.IX Item "canonpath (override)"
Removes redundant portions of file specifications according to \s-1VMS\s0 syntax.
.IP "catdir" 4
.IX Item "catdir"
Concatenates a list of file specifications, and returns the result as a
VMS-syntax directory specification.  No check is made for \*(L"impossible\*(R"
cases (e.g. elements other than the first being absolute filespecs).
.IP "catfile" 4
.IX Item "catfile"
Concatenates a list of file specifications, and returns the result as a
VMS-syntax file specification.
.IP "curdir (override)" 4
.IX Item "curdir (override)"
Returns a string representation of the current directory: '[]'
.IP "devnull (override)" 4
.IX Item "devnull (override)"
Returns a string representation of the null device: '_NLA0:'
.IP "rootdir (override)" 4
.IX Item "rootdir (override)"
Returns a string representation of the root directory: 'SYS$DISK:[000000]'
.IP "tmpdir (override)" 4
.IX Item "tmpdir (override)"
Returns a string representation of the first writable directory
from the following list or '' if none are writable:
.Sp
.Vb 2
\&    sys$scratch:
\&    $ENV{TMPDIR}
.Ve
.Sp
Since perl 5.8.0, if running under taint mode, and if \f(CW$ENV\fR{\s-1TMPDIR\s0}
is tainted, it is not used.
.IP "updir (override)" 4
.IX Item "updir (override)"
Returns a string representation of the parent directory: '[\-]'
.IP "case_tolerant (override)" 4
.IX Item "case_tolerant (override)"
\&\s-1VMS\s0 file specification syntax is case\-tolerant.
.IP "path (override)" 4
.IX Item "path (override)"
Translate logical name \s-1DCL$PATH\s0 as a searchlist, rather than trying
to \f(CW\*(C`split\*(C'\fR string value of \f(CW$ENV{'PATH'}\fR.
.IP "file_name_is_absolute (override)" 4
.IX Item "file_name_is_absolute (override)"
Checks for \s-1VMS\s0 directory spec as well as Unix separators.
.IP "splitpath (override)" 4
.IX Item "splitpath (override)"
Splits using \s-1VMS\s0 syntax.
.IP "splitdir (override)" 4
.IX Item "splitdir (override)"
Split dirspec using \s-1VMS\s0 syntax.
.IP "catpath (override)" 4
.IX Item "catpath (override)"
Construct a complete filespec using \s-1VMS\s0 syntax
.IP "abs2rel (override)" 4
.IX Item "abs2rel (override)"
Use \s-1VMS\s0 syntax when converting filespecs.
.IP "rel2abs (override)" 4
.IX Item "rel2abs (override)"
Use \s-1VMS\s0 syntax when converting filespecs.
