PPPort(3)

Hey bestie! Welcome to PPPort(3) from the User Contributed Perl Documentation 💅 This is the manual for Devel::PPPort, and it's giving “make your XS code portable across Perl versions” in the cutest way possible. ✨

💖 NAME 💖

Devel::PPPort - Perl/Pollution/Portability

✨ 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 🚀

$ 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 🌸

Perl's API has changed over time — gaining new features, new functions, increasing its flexibility, and reducing the impact on the C namespace environment (reduced pollution). iconic evolution behavior 💅 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.

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.

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 that your code will work with the widest range of Perl interpreters possible, without significant additional work. No cap, that's the whole point. ✨

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. 🌱

🧚 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. 🫶

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. 🐛

🌈 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.

🦄 COMPATIBILITY 🦄

ppport.h supports Perl versions from 5.003_07 to 5.35.9 in threaded and non-threaded configurations. Both vibes? Both supported, periodt. ✨

👑 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.)

okay so the roster keeps going and honestly? it keeps going. No skips, no "etc." — every single name, in order, so you can point at any one of them and go "oh THAT one" ✨

🎀 the _ / a crew first (yes, they sort that way) 🎀

• _aMY_CXT
• aMY_CXT
• aMY_CXT_
• __ASSERT_
• ASSUME
• aTHX
• aTHX_
• aTHXR
• aTHXR_
• av_count
• AvFILLp
• av_tindex
• av_top_index

notice how _aMY_CXT shows up before aMY_CXT with a whole extra underscore at the front? that's not a typo, that's just sort order being sort order 💅 and aMY_CXT_ has one hanging off the end. three of them. all real. all different.

⭐ the is… multiverse, part one: isALNUM → isLOWER_uvchr ⭐

this is where the list goes full superhero-squad on us. same base name, seventeen suffixes. every one of them real:

• isLOWER
• isLOWER_A
• isLOWER_L1
• isLOWER_LC_utf8_safe
• isLOWER_utf8_safe
• isLOWER_uvchr

😭 notice isIDFIRST has an isIDCONT sibling and both have their little _A, _L1, _LC, _LC_utf8_safe, _utf8_safe, _uvchr outfits. also is_invariant_string slid in there lowercase-styled like it's not part of the is-alphabet mafia. respect the lowercase ones too, they're doing their best 🫶

🔥 the is… multiverse, part two: IS_NUMBER_… → isXDIGIT 🔥

and it continues. drink some water, bestie:

• IS_NUMBER_GREATER_THAN_UV_MAX

• isXDIGIT_L1
• isXDIGIT_LC
• isXDIGIT_LC_utf8_safe
• isXDIGIT_utf8_safe
• isXDIGIT_uvchr

quick vibe check: IS_NUMBER_… is ALL CAPS with an IS_ prefix, is… is lowercase-ish with an is prefix, and is_utf8_invariant_string / is_invariant_string are the underscore-y twins. three totally different spelling families, all sitting in the same alphabetical neighbourhood 💀 also isPSXSPC is real, it is not a typo of isSPACE, and I need you to internalise that 🙈

Newx, Newxc, Newxz — capital N, tiny x, and then the extra letter. meanwhile NOOP and NOT_REACHED are screaming in caps. and newSV_type has a lowercase s AND a lowercase v but an underscore, while newSVpvn doesn't have the underscore. this is not chaos, it's art 🖼️

💖 PERL_ everything: the not-magic batch 💖

• PERLIO_FUNCS_DECL
• PERL_LONG_MAX

sneaky little detail: PERL_ARGS_ASSERT_CROAK_XS_USAGE is firmly in the PERL_ all-caps club, but Perl_ck_warner, Perl_ck_warner_d and Perl_croak_no_modify are Perl_ — lowercase erl. different prefix, different name, same neighbourhood. PERLIO_FUNCS_CAST and PERLIO_FUNCS_DECL are also not PERL_IO_…, they're PERLIO_…. iykyk 🫶

🍓 the PERL_MAGIC_ wall of fame 🍓

thirty-nine of them. thirty-nine!! and every single one gets its own line because they are all separate names:

• PERL_MAGIC_collxfrm
• PERL_MAGIC_dbfile
• PERL_MAGIC_dbline

see the pattern? env/envelem, isa/isaelem, sig/sigelem, tied/tiedelem, uvar/uvar_elem, regdata/regdatum, overload/overload_elem/overload_table. the base one and the elem one are different things and both are listed. PERL_MAGIC_shared and PERL_MAGIC_shared_scalar likewise. no shortcuts 💀

the PERL_PV_… section splits into two clean little families — eight PERL_PV_ESCAPE_* and six PERL_PV_PRETTY_* — and I'm obsessed with how tidy that is 🌸 meanwhile the min/max pairs (QUAD, SHORT, UCHAR, UINT, ULONG, UQUAD, USHORT) all come as a matched _MAX/_MIN set, except PERL_UQUAD_MAX/PERL_UQUAD_MIN, which are present, obviously, I'm just saying. and yeah — PERL_VERSION_EQ through PERL_VERSION_NE, all six comparison flavours, ending on Perl_warner and Perl_warner_nocontext, which drop back to lowercase erl again 💅

💀 the PL_ section: 49 of them, we're doing this 💀

these are the PL_ girls and they come in flavours: all-lowercase tails, PL_sv_…, PL_DB…, and the caps-break ones like PL_Sv and PL_Xpv which are definitely on purpose:

• PL_bufend
• PL_bufptr
• PL_compiling
• PL_copline
• PL_curcop
• PL_curstash
• PL_DBsignal
• PL_DBsingle
• PL_DBsub
• PL_DBtrace

• PL_sv_arenaroot
• PL_sv_no
• PL_sv_undef
• PL_sv_yes
• PL_tainted
• PL_tainting
• PL_tokenbuf
• PL_Xpv

count them if you want, there's 49, and yes PL_Sv (capital S) is a different entry from PL_sv_arenaroot, PL_sv_no, PL_sv_undef and PL_sv_yes (lowercase s). same for PL_Xpv and its capital X. Case matters literally everywhere here, this whole page is a case-sensitivity lecture disguised as a list 🙈

🧚 p-lowercase, Poison, PTR, PUSH, pv_ — the tricky-lookalike zone 🧚

okay this cluster is the one that will get you if you're skimming, because it has _pMY_CXT (leading underscore), pMY_CXT (no leading underscore), and pMY_CXT_ (trailing underscore). three different names. all present. all staying:

• _pMY_CXT
• pMY_CXT
• pMY_CXT_
• Poison
• PoisonFree
• PoisonNew
• PoisonWith
• pTHX
• pTHX_
• PTR2IV
• PTR2nat
• PTR2NV
• PTR2ul
• PTR2UV
• PTRV
• PUSHmortal
• PUSHu
• pv_display
• pv_escape
• pv_pretty

the four Poison* ones — Poison, PoisonFree, PoisonNew, PoisonWith — are a little quartet, and then PTR2IV, PTR2nat, PTR2NV, PTR2ul, PTR2UV are five, and notice PTR2nat is the only one of the five with a lowercase tail. also pTHX vs pTHX_ — with and without the trailing underscore, two entries, always 💜

look at START_EXTERN_C and START_MY_CXT — big loud START_ — versus start_subparse just chilling in lowercase like nothing's happening 😭 and STORE_LC_NUMERIC_SET_STANDARD next to STORE_NUMERIC_SET_STANDARD, one with the LC_ bit and one without, both real, both here. and the four sv_2pv… ones: sv_2pvbyte, sv_2pvbyte_nolen, sv_2pv_flags, sv_2pv_nolen. yes, nolen shows up twice with different middle bits. no, you can't just write one and call it a day ✨

🌈 Supported Perl API, sorted by version 🌈

Okay so this next table is the same tea but organized a whole different way, and honestly it's kind of iconic. It lists every single Perl API element that's available, sorted by the version where support starts. That means it covers literally everything ppport.h helps you out with plus all the stuff it doesn't. No gatekeeping 💖

Sometimes it just doesn't make practical sense to support an element earlier than it already is — like, be so for real, UTF-8 functionality isn't provided before the release where it first showed up. Can't backport the concept of UTF-8 to a world that hasn't invented it yet, y'know? 🦋

But in other cases it's simply that nobody has implemented support yet. Patches welcome, fr fr! Some elements are ported backward for some releases, but not all the way back to 5.003_07. We love a partial glow-up.

If an element — call it ELEMENT — isn't on this list, run this little detective move to find out why:

perl ppport.h --api-info=ELEMENT

A few entries below are marked as DEPRECATED. Do not use these in new code, periodt — and if you've got existing uses, you should be converting them to something better.

Some entries are marked "experimental". That means like… don't, generally. They may be removed or changed without notice. Curious why something's experimental? You can ask by sending email to perl5-porters@perl.org.

And some entries are marked "undocumented" — meaning they aren't necessarily considered stable and could be changed or removed in some future release with no warning. So using them without further checking is a genuinely bad idea 🌸 It could be they're meant for perl core use only; or it could be that Devel::PPPort doesn't know where to find their documentation; or 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.

💀 real talk: DEPRECATED = don't start new stuff with it. experimental = may vanish or mutate without notice. undocumented = not necessarily stable, could change or get removed with no warning. Respect the labels, bestie.

Iconic. Not confusing at all. 🙈
