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.
eliminate_macros
Expands MM[ KS ]/Make macros in a text string, using the contents of identically named elements of %$self, and returns the result as a file specification in Unix syntax.
fixpath
Catchall routine to clean up problem MM[ SK ]/Make macros. Expands macros in any directory specification, in order to avoid juxtaposing two VMS-syntax directories when MM[ SK ] is run. Also expands expressions which are all macro, so that we can tell how long the expansion is, and avoid overrunning DCL ’s command buffer when MM[ KS ] is running.
If optional second argument has a TRUE value, then the return string is a VMS-syntax directory specification, if it is FALSE , the return string is a VMS-syntax file specification, and if it is not specified, fixpath() checks to see whether it matches the name of a directory in the current default directory, and returns a directory or file specification accordingly.
Methods
always loaded
canonpath (override)
Removes redundant portions of file specifications according to VMS syntax.
catdir
Concatenates a list of file specifications, and returns the result as a VMS-syntax directory specification. No check is made for "impossible" cases (e.g. elements other than the first being absolute filespecs).
catfile
Concatenates a list of file specifications, and returns the result as a VMS-syntax file specification.
curdir (override)
Returns a string representation of the current directory: ’[]’
devnull (override)
Returns a string representation of the null device: ’_NLA0:’
rootdir (override)
Returns a string representation of the root directory: ’SYS$DISK:[000000]’
tmpdir (override)
Returns a string representation of the first writable directory from the following list or ’’ if none are writable:
sys$scratch:
$ENV{TMPDIR}
Since perl 5.8.0, if running under taint mode, and if $ENV{ TMPDIR } is tainted, it is not used.
updir (override)
Returns a string representation of the parent directory: ’[−]’
case_tolerant (override)
VMS file specification syntax is case−tolerant.
path (override)
Translate logical name DCL$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)
Splits using VMS syntax.
splitdir (override)
Split dirspec using VMS syntax.
catpath (override)
Construct a complete filespec using VMS syntax
abs2rel (override)
Use VMS syntax when converting filespecs.
rel2abs (override)
Use VMS syntax when converting filespecs.
See File::Spec and File::Spec::Unix. This package overrides the implementation of these methods, not the semantics.
