💖 Devel::PPPort 💖

okay bestie, gather round, because this is Devel::PPPort — the Perl/Pollution/Portability module, straight from the Perl Programmers Reference Guide section of your friendly neighborhood manual. it's giving "your XS code works on ancient Perls too" and honestly? iconic. ✨

✨ NAME ✨

Devel::PPPort — Perl/Pollution/Portability 🦋

🌸 SYNOPSIS 🌸

look at this gorgeous little snippet, no notes:

Devel::PPPort::WriteFile();   # defaults to ./ppport.h
Devel::PPPort::WriteFile('someheader.h');

# Same as above but retrieve contents rather than write file
my $contents = Devel::PPPort::GetFileContents();
my $contents = Devel::PPPort::GetFileContents('someheader.h');

and here's how you actually start using Devel::PPPort for XS projects, step by step bestie:

$ cpan Devel::PPPort
$ perl -MDevel::PPPort -e'Devel::PPPort::WriteFile'
$ perl ppport.h --compat-version=5.6.1 --patch=diff.patch *.xs
$ patch -p0 < diff.patch
$ echo ppport.h >>MANIFEST

👑 DESCRIPTION 👑

so here's the tea 🍓: Perl's API has changed over time. it keeps gaining new features, new functions, more flexibility, and it's been reducing the impact on the C namespace environment (that's the whole "reduced pollution" thing, iykyk). the header file this module writes — usually called ppport.h — tries its absolute best to bring some of those newer Perl API features to older versions of Perl. which means you can worry less about keeping track of every old release ever, while your users still get to reap the benefit. main character energy for everybody involved, honestly. 💅

Devel::PPPort contains two functions: WriteFile and GetFileContents. WriteFile's only purpose in life is to write the ppport.h C header file. that file contains a series of macros and — if you explicitly ask for them — functions that let XS modules be built using older versions of Perl. currently, Perl versions from 5.003_07 to 5.35.9 are supported. periodt. ⭐

GetFileContents can be used to retrieve the file contents rather than writing it out.

this module is used by h2xs to write the file ppport.h. 🎀

🧚 Why use ppport.h? 🧚

you should use ppport.h in modern code so your code works with the widest range of Perl interpreters possible, without significant additional work. no cap, that's just free real estate.

you should attempt to get older code to fully use ppport.h, because the reduced pollution of newer Perl versions is an important thing. it's so important that the old polluting ways of original Perl modules will not be supported very far into the future, and your module will almost certainly break! 😭 so by adapting to it now, you'll gain compatibility and a sense of having done the electronic ecology some good. look at you, saving the ecosystem, so proud. 🌈

🌟 How to use ppport.h 🌟

do not direct the users of your module to download Devel::PPPort. they are most probably not XS writers, bestie, don't do that to them. also, don't make ppport.h optional. instead, just take the most recent copy of ppport.h that you can find (e.g. by generating it with the latest Devel::PPPort release from CPAN), copy it into your project, adjust your project to use it, test it, and distribute the header along with your module. slay. ✨

it is important to use the most recent version of ppport.h. but you do need to test before shipping a newer version than the one you already had. one possible failure is that someone had to convert a backported element from a macro into a function, and actual functions must be enabled with a NEED macro to minimize the possibility of namespace pollution. see HACKERS for details. the developers of Devel::PPPort want to hear if there are other problems that arise from using a later ppport.h. use <https://github.com/Dual-Life/Devel-PPPort/issues> to report any. 🫶

💀 Running ppport.h 💀

but ppport.h is more than just a C header. it's also a Perl script that can check your source code! 📝 it will suggest hints and portability notes, and can even make suggestions on how to change your code. you can run it like any other Perl program:

perl ppport.h [options] [files]

it also has embedded documentation, so you can use

perldoc ppport.h

to find out more about how to use it. 🦋

🎀 FUNCTIONS 🎀

✨ WriteFile ✨

WriteFile takes one optional argument. when called with one argument, it expects to be passed a filename. when called with no arguments, it defaults to the filename ppport.h.

the function returns a true value if the file was written successfully. otherwise it returns a false value. 😌

💜 GetFileContents 💜

GetFileContents behaves like WriteFile above, but returns the contents of the would-be file rather than writing it out. same vibes, no actual file left behind. 🌸

🔥 COMPATIBILITY 🔥

ppport.h supports Perl versions from 5.003_07 to 5.35.9 in threaded and non-threaded configurations. yes, both. we don't play favorites. 👑

🌈 Provided Perl compatibility API 🌈

the header file written by this module, typically ppport.h, provides access to the following elements of the Perl API that are not otherwise available in Perl releases older than when those elements were first introduced. (note that many of these are not supported all the way back to 5.003_07, but it may be that they are supported back as far as you need — see "Supported Perl API, sorted by version" for that information.) ⭐

more coming, bestie, don't go anywhere 💅

okay bestie, the roll call is NOT over, and honestly she is barely getting warmed up 💅 so grab your iced coffee, because this is the rest of the guest list: every single macro, function, and variable that Devel::PPPort will lovingly back-fill for you so your XS code doesn't crumble on an ancient Perl. No descriptions down here — these are just the names, alphabetized, iconic, unbothered. 🎀

✨ the underscore-and-`a` girlies ✨

Leading underscore? Cute. Lowercase a? Also cute. This is where the context macros and the array helpers chill.

💖 the `C` section: callers, warnings, and cops 💖

This is where the call_* squad hangs out, plus the entire ckWARN/ck_warner warning family, the Cop* accessors, and the croak_* crew (they're dramatic, they throw, that's the vibe).

🌸 `E` is for eval, extern, and ✨error✨ energy 🌸

Short and spicy. Four of these are about calling into Perl from C, one's about closing an extern "C" block, and ERRSV is just there, judging.

One (1) entry. She doesn't need company. She's doing case-folding-adjacent business and she's thriving.

💜 Supported Perl API, sorted by version 💜

okay bestie, this next bit is the full buffet, but sorted by which perl release first blessed us with it ✨. The list below has literally everything — every API element that exists, all of it — including the stuff ppport.h is out here helping you with and the stuff it does absolutely nothing about. No gatekeeping here, we tell you about the whole squad 🫶

Now, some of these are just... not gonna time-travel for you, and that's not a skill issue, it's a physics issue. Like, UTF-8 functionality? It genuinely does not exist prior to the release where it was first introduced. Nothing to backport, the code wasn't born yet 😭

But other ones? It's purely that nobody has implemented support yet. So if you're feeling generous: patches welcome! 💖 Some elements got ported backward for some releases, but not all the way back to 5.003_07. Sad but true.

If some element — call it ELEMENT — isn't showing up on this list, you can sleuth it out yourself with:

perl ppport.h --api-info=ELEMENT

A few entries below are tagged DEPRECATED. Do not use those in new code, and if you've got them chilling in existing code, you should be migrating them to something better. Respectfully, move on 💅

Some entries are tagged "experimental". That means, generally speaking, don't use them. They can get yanked or rewritten with zero notice, no cap. Curious why one of them is experimental? Email the crew at <mailto:perl5-porters@perl.org> 📧

And some entries are tagged "undocumented". That's your signal that they are not necessarily considered stable and could be changed or removed in some future release without warning. So yeah, using them without further checking is a bad idea, periodt. Could be they're perl-core-use-only 👑. Or could be that Devel::PPPort just doesn't know where their docs live, or that it's simply an oversight that nobody documented them yet. Either way, if you want to use one — and maybe even get it backported — send mail to <mailto:perl5-porters@perl.org> first 💌
