ExtUtils::Command::MM - Commands for the MM’s to use in Makefiles


  perl "-MExtUtils::Command::MM" -e "function" "--" arguments...


FOR INTERNAL USE ONLY! The interface is not stable.
ExtUtils::Command::MM encapsulates code which would otherwise have to be done with large one liners.
Any $(FOO) used in the examples are make variables, not Perl.
  test_harness($verbose, @test_libs);

Runs the tests on @ARGV via Test::Harness passing through the $verbose flag. Any @test_libs will be unshifted onto the test’s @INC.
@test_libs are run in alphabetical order.
  pod2man( --option=value,
           $podfile1 => $manpage1,
           $podfile2 => $manpage2,

  # or args on @ARGV

pod2man() is a function performing most of the duties of the pod2man program. Its arguments are exactly the same as pod2man as of 5.8.0 with the addition of:
    --perm_rw   octal permission to set the resulting manpage to

And the removal of:

If no arguments are given to pod2man it will read from @ARGV.
If Pod::Man is unavailable, this function will warn and return undef.
  perl "-MExtUtils::Command::MM" -e warn_if_old_packlist <somefile>

Displays a warning that an old packlist file was found. Reads the filename from @ARGV.
    perl "-MExtUtils::Command::MM" -e perllocal_install
        <type> <module name> <key> <value> ...

    # VMS only, key|value pairs come on STDIN
    perl "-MExtUtils::Command::MM" -e perllocal_install
        <type> <module name> < <key>|<value> ...

Prints a fragment of POD suitable for appending to perllocal.pod. Arguments are read from @ARGV.
’type’ is the type of what you’re installing. Usually ’Module’.
’module name’ is simply the name of your module. (Foo::Bar)
Key/value pairs are extra information about the module. Fields include:
    installed into      which directory your module was out into
    LINKTYPE            dynamic or static linking
    VERSION             module version number
    EXE_FILES           any executables installed in a space separated

    perl "-MExtUtils::Command::MM" -e uninstall <packlist>

A wrapper around ExtUtils::Install::uninstall(). Warns that uninstallation is deprecated and doesn’t actually perform the uninstallation.
   perl "-MExtUtils::Command::MM" -e test_s <file>

Tests if a file exists and is not empty (size > 0). Exits with 0 if it does, 1 if it does not.
  perl "-MExtUtils::Command::MM" -e cp_nonempty <srcfile> <dstfile> <perm>

Tests if the source file exists and is not empty (size > 0). If it is not empty it copies it to the given destination with the given permissions.
