EXTUTILS::COMMAND::MM(3pm)

🎀 NAME 🎀

okay bestie, welcome to ExtUtils::Command::MM(3pm), straight outta the Perl Programmers Reference Guide ✨

ExtUtils::Command::MM — Commands for the MM's to use in Makefiles 💅

---

✨ SYNOPSIS ✨

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

---

💖 DESCRIPTION 💖

FOR INTERNAL USE ONLY! The interface is not stable. Like, do not build your whole personality on this API, bestie 😭

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. Just so we're clear 🫶

🌸 test_harness

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. Slay, organized queen 👑

🦋 pod2man

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:

--verbose/-v
--help/-h

If no arguments are given to pod2man, it will read from @ARGV.

If Pod::Man is unavailable, this function will warn and return undef. Not ideal, but at least it tells you 😭

💜 warn_if_old_packlist

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. It's giving warning, but make it cute 💅

🌈 perllocal_install

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. Like Foo::Bar — iconic naming convention, no notes.

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 list

🫶 uninstall

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. So it's more of a vibe check than an actual uninstall, bestie 💀

⭐ test_s

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. Simple, clean, effective 👑

💖 cp_nonempty

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. Copy queen behavior, honestly 🎀
