💅 Devel::PPPort(3pm) — Perl Programmers Reference Guide

okay so bestie, this is Devel::PPPort — Perl/Pollution/Portability — and it's genuinely one of those modules that quietly keeps the whole XS ecosystem from falling apart. let's get into it 🌸

✨ NAME ✨

Devel::PPPort — Perl/Pollution/Portability. yes that's the whole name, she's got range 🎀

🦋 SYNOPSIS 🦋

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');

⭐ Start using Devel::PPPort for XS projects

like, the whole vibe in five lines:

$ 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

slay. that's the workflow. copy it, love it, live it 💖

🌈 DESCRIPTION 🌈

Perl's API has literally changed over time — gaining new features, new functions, increasing its flexibility, and reducing the impact on the C namespace environment (that's the reduced pollution part, iykyk). The header file written by this module, typically ppport.h, attempts to bring some of the newer Perl API features to older versions of Perl, so that you can worry less about keeping track of old releases — but users can still reap the benefit. everyone wins, no cap ✨

Devel::PPPort contains two functions, WriteFile and GetFileContents. WriteFile's only purpose is to write the ppport.h C header file. This file contains a series of macros and, if explicitly requested, functions that allow XS modules to be built using older versions of Perl. Currently, Perl versions from 5.003_07 to 5.35.9 are supported. (yes, that's a lot of Perls, she's been busy 👑

GetFileContents can be used to retrieve the file contents rather than writing it out. same energy, different delivery method 🫶

This module is used by h2xs to write the file ppport.h. iconic collaboration honestly.

💜 Why use ppport.h?

You should use ppport.h in modern code so that your code will work with the widest range of Perl interpreters possible, without significant additional work. literally free compatibility, why would you not 🌸

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! 😭 By adapting to it now, you'll gain compatibility and a sense of having done the electronic ecology some good. main character eco-warrior energy fr fr 🌱

🎀 How to use ppport.h

Don't direct the users of your module to download Devel::PPPort. They are most probably not XS writers. Also, don't make ppport.h optional. Rather, 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. ship it with the header, bestie, don't make people go hunting 📦

It is important to use the most recent version of ppport.h. You do need to test before shipping a newer version than 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. they're literally asking, so tell them 🙈

🧚 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. like a little portability fairy godmother 🧚✨ 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. self-documenting queen 👑

🔥 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. simple. honest. reliable. we love her 💅

🍓 GetFileContents

GetFileContents behaves like WriteFile above, but returns the contents of the would-be file rather than writing it out. so it's WriteFile but it hands you the goods instead of putting them on disk 🫴✨

👑 COMPATIBILITY 👑

ppport.h supports Perl versions from 5.003_07 to 5.35.9 in threaded and non-threaded configurations. both flavors, all the way back, she's got you 🌈

🌸 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 the 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.) so like, check the version table before you assume, bestie 💜

okay so before we start unpacking individual entries one by one, here's the whole entire roll call 💖 this is the master list, alphabetically sorted, and it is long — but that's the point. Every single name here got a back-compat glow-up from Devel::PPPort, so if you're porting some crusty XS code and wanna know "does PPPort have my back on this one?", you scroll this list.

no skips. no "and so on". no cap.

📋 LIST OF API FUNCTIONS ✨

read it like a menu, bestie — find your name, then go find its entry. a couple of things to keep in mind while you scan:

  • the ordering is plain alphabetical, so yes, the very first entry starts with an underscore and the case-sensitivity is exactly how it looks 🫶
  • capital letters matter, lowercase matters, trailing underscores matter. aMY_CXT, aMY_CXT_, and _aMY_CXT are three different things and they all live here. the way that C does not play about naming 💀
  • do not "clean up" any of these when you copy them into your source. copy them character for character or the compiler will simply not recognize you 🙈
  • there are groups in here that lowkey look like families (the is* character-class posse, the PERL_MAGIC_* collection, the PL_* globals) and they are — vibe with them, don't merge them 🌸

and now, the list 💅

okay that was a lot of scrolling and you ate every single line, iconic behavior honestly 👑 this list is your lookup table — half the battle in XS porting is just knowing the exact spelling of the thing you want, and now you have it, verbatim, no guessing, no typo-induced despair 😭

keep it open in a split pane, Ctrl+F your way through it, and remember: nothing here is decorative. every name is a real thing you can reach for when your extension needs to work on older perls too 🦋

✨ Supported Perl API, sorted by version ✨

Okay so this table is the whole entire tea: it lists every Perl API element that's available, sorted by the version where support starts. And yes, that means it includes everything ppport.h helps you out with plus the stuff it doesn't. 💅

Some cases it just doesn't make practical sense to support an element earlier than it already is — like, UTF-8 functionality isn't provided prior to the release where it was first introduced. That's just how the timeline goes, bestie. 🕰️

But in other cases, it's simply that no one has implemented support yet. Patches welcome, fr fr! Some elements are ported backward for some releases, but not all the way to 5.003_07.

So if an element — call it ELEMENT — isn't on this list, run this and find out why:

perl ppport.h --api-info=ELEMENT

A few entries below are marked as DEPRECATED. Do not use those for new code, and if you've already got them in existing code you should be converting those uses to something better. Periodt. 💀

Some entries are marked "experimental". That means you should not generally use them — they may be removed or changed without notice. Wanna know why something's experimental? You can ask by sending email to perl5-porters@perl.org. 📧

And some entries are marked "undocumented". That means they aren't necessarily considered stable, and could be changed or removed in some future release without warning. So it's a bad idea to use them without further checking. It could be that they're considered perl-core-use-only; or it could be that Devel::PPPort doesn't know where to find their documentation, or that it's just an oversight that they haven't been documented. If you want to use one — and potentially have it backported — first send mail to perl5-porters@perl.org. 🫶
