NAME

6       File::Spec::VMS - methods for VMS file specs
7

SYNOPSIS

9        require File::Spec::VMS; # Done internally by File::Spec if needed
10

DESCRIPTION

12       See File::Spec::Unix for a documentation of the methods provided there.
13       This package overrides the implementation of these methods, not the
14       semantics.
15
16       The default behavior is to allow either VMS or Unix syntax on input and
17       to return VMS syntax on output, even when Unix syntax was given on
18       input.
19
20       When used with a Perl of version 5.10 or greater and a CRTL possessing
21       the relevant capabilities, override behavior depends on the CRTL
22       features "DECC$FILENAME_UNIX_REPORT" and "DECC$EFS_CHARSET".  When the
23       "DECC$EFS_CHARSET" feature is enabled and the input parameters are
24       clearly in Unix syntax, the output will be in Unix syntax.  If
25       "DECC$FILENAME_UNIX_REPORT" is enabled and the output syntax cannot be
26       determined from the input syntax, the output will be in Unix syntax.
27
28       canonpath (override)
29           Removes redundant portions of file specifications according to the
30           syntax detected.
31
32       catdir (override)
33           Concatenates a list of file specifications, and returns the result
34           as a directory specification.  No check is made for "impossible"
35           cases (e.g. elements other than the first being absolute
36           filespecs).
37
38       catfile (override)
39           Concatenates a list of directory specifications with a filename
40           specification to build a path.
41
42       curdir (override)
43           Returns a string representation of the current directory: '[]' or
44           '.'
45
46       devnull (override)
47           Returns a string representation of the null device: '_NLA0:' or
48           '/dev/null'
49
50       rootdir (override)
51           Returns a string representation of the root directory:
52           'SYS$DISK:[000000]' or '/'
53
54       tmpdir (override)
55           Returns a string representation of the first writable directory
56           from the following list or '' if none are writable:
57
58               /tmp if C<DECC$FILENAME_UNIX_REPORT> is enabled.
59               sys$scratch:
60               $ENV{TMPDIR}
61
62           Since perl 5.8.0, if running under taint mode, and if $ENV{TMPDIR}
63           is tainted, it is not used.
64
65       updir (override)
66           Returns a string representation of the parent directory: '[-]' or
67           '..'
68
69       case_tolerant (override)
70           VMS file specification syntax is case-tolerant.
71
72       path (override)
73           Translate logical name DCL$PATH as a searchlist, rather than trying
74           to "split" string value of $ENV{'PATH'}.
75
76       file_name_is_absolute (override)
77           Checks for VMS directory spec as well as Unix separators.
78
79       splitpath (override)
80               ($volume,$directories,$file) = File::Spec->splitpath( $path );
81               ($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file );
82
83           Passing a true value for $no_file indicates that the path being
84           split only contains directory components, even on systems where you
85           can usually (when not supporting a foreign syntax) tell the
86           difference between directories and files at a glance.
87
88       splitdir (override)
89           Split a directory specification into the components.
90
91       catpath (override)
92           Construct a complete filespec.
93
94       abs2rel (override)
95           Attempt to convert a file specification to a relative
96           specification.  On a system with volumes, like VMS, this may not be
97           possible.
98
99       rel2abs (override)
100           Return an absolute file specification from a relative one.
