# NAME

Module::Build::Platform::VMS - Builder class for VMS platforms

# DESCRIPTION

This module inherits from `Module::Build::Base` and alters a few minor details of its functionality. Please see Module::Build for the general docs.

## Overridden Methods

- _set_defaults

  Change $self->{build_script} to 'Build.com' so @Build works.

- cull_args

  '@Build foo' on VMS will not preserve the case of 'foo'. Rather than forcing people to write '@Build "foo"' we'll dispatch case-insensitively.

- manpage_separator

  Use '__' instead of '::'.

- prefixify

  Prefixify taking into account VMS' filepath syntax.

- _quote_args

  Command-line arguments (but not the command itself) must be quoted to ensure case preservation.

- have_forkpipe

  There is no native fork(), so some constructs depending on it are not available.

- _backticks

  Override to ensure that we quote the arguments but not the command.

- find_command

  Local an executable program

- _maybe_command (override)

  Follows VMS naming conventions for executable files. If the name passed in doesn't exactly match an executable file, appends .Exe (or equivalent) to check for executable image, and .Com to check for DCL procedure. If this fails, checks directories in DCL$PATH and finally Sys$System: for an executable file having the name specified, with or without the .Exe-equivalent suffix.

- do_system

  Override to ensure that we quote the arguments but not the command.

- oneliner

  Override to ensure that we do not quote the command.

- _infer_xs_spec

  Inherit the standard version but tweak the library file name to be something Dynaloader can find.

- rscan_dir

  Inherit the standard version but remove dots at end of name. If the extended character set is in effect, do not remove dots from filenames with Unix path delimiters.

- dist_dir

  Inherit the standard version but replace embedded dots with underscores because a dot is the directory delimiter on VMS.

- man3page_name

  Inherit the standard version but chop the extra manpage delimiter off the front if there is one. The VMS version of splitdir('[.foo]') returns '', 'foo'.

- expand_test_dir

  Inherit the standard version but relativize the paths as the native glob() doesn't do that for us.

- _detildefy

  The home-grown glob() does not currently handle tildes, so provide limited support here. Expect only UNIX format file specifications for now.

- find_perl_interpreter

  On VMS, $^X returns the fully qualified absolute path including version number. It's logically impossible to improve on it for getting the perl we're currently running, and attempting to manipulate it is usually lossy.

- localize_file_path

  Convert the file path to the local syntax

- localize_dir_path

  Convert the directory path to the local syntax

- ACTION_clean

  The home-grown glob() expands a bit too aggressively when given a bare name, so default in a zero-length extension.
