This requires a working diff program +to be installed on your system. + +=head2 --copy=I<suffix> + +If this option is given, a copy of each file will be saved with +the given suffix that contains the suggested changes. This does +not require any external programs. Note that this does not +automagially add a dot between the original filename and the +suffix. If you want the dot, you have to include it in the option +argument. + +If neither C<--patch> or C<--copy> are given, the default is to +simply print the diffs for each file. This requires either +C<Text::Diff> or a C<diff> program to be installed. + +=head2 --diff=I<program> + +Manually set the diff program and options to use. The default +is to use C<Text::Diff>, when installed, and output unified +context diffs. + +=head2 --compat-version=I<version> + +Tell F<ppport.h> to check for compatibility with the given +Perl version. The default is to check for compatibility with Perl +version __MIN_PERL__. You can use this option to reduce the output +of F<ppport.h> if you intend to be backward compatible only +down to a certain Perl version. + +=head2 --cplusplus + +Usually, F<ppport.h> will detect C++ style comments and +replace them with C style comments for portability reasons. +Using this option instructs F<ppport.h> to leave C++ +comments untouched. + +=head2 --quiet + +Be quiet. Don't print anything except fatal errors. + +=head2 --nodiag + +Don't output any diagnostic messages. Only portability +alerts will be printed. + +=head2 --nohints + +Don't output any hints. Hints often contain useful portability +notes. Warnings will still be displayed. + +=head2 --nochanges + +Don't suggest any changes. Only give diagnostic output and hints +unless these are also deactivated. + +=head2 --nofilter + +Don't filter the list of input files. By default, files not looking +like source code (i.e. not *.xs, *.c, *.cc, *.cpp or *.h) are skipped. + +=head2 --strip + +Strip all script and documentation functionality from F<ppport.h>. +This reduces the size of F<ppport.h> dramatically and may be useful +if you want to include F<ppport.h> in smaller modules without +increasing their distribution size too much. + +The stripped F<ppport.h> will have a C<--unstrip> option that allows +you to undo the stripping, but only if an appropriate C<Devel::PPPort> +module is installed. + +=head2 --list-provided + +Lists the API elements for which compatibility is provided by +F<ppport.h>. Also lists if it must be explicitly requested, +if it has dependencies, and if there are hints or warnings for it. + +=head2 --list-unsupported + +Lists the API elements that are known not to be supported by +F<ppport.h> and below which version of Perl they probably +won't be available or work. + +=head2 --api-info=I<name> + +Show portability information for API elements matching I<name>. +If I<name> is surrounded by slashes, it is interpreted as a regular +expression. + +=head1 DESCRIPTION + +In order for a Perl extension (XS) module to be as portable as possible +across differing versions of Perl itself, certain steps need to be taken. + +=over 4 + +=item * + +Including this header is the first major one. This alone will give you +access to a large part of the Perl API that hasn't been available in +earlier Perl releases. Use + + perl ppport.h --list-provided + +to see which API elements are provided by ppport.h. + +=item * + +You should avoid using deprecated parts of the API. For example, using +global Perl variables without the C<PL_> prefix is deprecated. Also, +some API functions used to have a C<perl_> prefix. Using this form is +also deprecated. You can safely use the supported API, as F<ppport.h> +will provide wrappers for older Perl versions. + +=item * + +If you use one of a few functions or variables that were not present in +earlier versions of Perl, and that can't be provided using a macro, you +have to explicitly request support for these functions by adding one or +more C<#define>s in your source code before the inclusion of F<ppport.h>. + +These functions or variables will be marked C<explicit> in the list shown +by C<--list-provided>. + +Depending on whether you module has a single or multiple files that +use such functions or variables, you want either C<static> or global +variants. + +For a C<static> function or variable (used only in a single source +file), use: + + #define NEED_function + #define NEED_variable + +For a global function or variable (used in multiple source files), +use: + + #define NEED_function_GLOBAL + #define NEED_variable_GLOBAL + +Note that you mustn't have more than one global request for the +same function or variable in your project. + + __EXPLICIT_API__ + +To avoid namespace conflicts, you can change the namespace of the +explicitly exported functions / variables using the C<DPPP_NAMESPACE> +macro. Just C<#define> the macro before including C<ppport.h>: + + #define DPPP_NAMESPACE MyOwnNamespace_ + #include "ppport.h" + +The default namespace is C<DPPP_>. + +=back + +The good thing is that most of the above can be checked by running +F<ppport.h> on your source code. See the next section for +details. + +=head1 EXAMPLES + +To verify whether F<ppport.h> is needed for your module, whether you +should make any changes to your code, and whether any special defines +should be used, F<ppport.h> can be run as a Perl script to check your +source code. Simply say: + + perl ppport.h + +The result will usually be a list of patches suggesting changes +that should at least be acceptable, if not necessarily the most +efficient solution, or a fix for all possible problems. + +If you know that your XS module uses features only available in +newer Perl releases, if you're aware that it uses C++ comments, +and if you want all suggestions as a single patch file, you could +use something like this: + + perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff + +If you only want your code to be scanned without any suggestions +for changes, use: + + perl ppport.h --nochanges + +You can specify a different C<diff> program or options, using +the C<--diff> option: + + perl ppport.h --diff='diff -C 10' + +This would output context diffs with 10 lines of context. + +If you want to create patched copies of your files instead, use: + + perl ppport.h --copy=.new + +To display portability information for the C<newSVpvn> function, +use: + + perl ppport.h --api-info=newSVpvn + +Since the argument to C<--api-info> can be a regular expression, +you can use + + perl ppport.h --api-info=/_nomg$/ + +to display portability information for all C<_nomg> functions or + + perl ppport.h --api-info=/./ + +to display information for all known API elements. + +=head1 BUGS + +If this version of F<ppport.h> is causing failure during +the compilation of this module, please check if newer versions +of either this module or C<Devel::PPPort> are available on CPAN +before sending a bug report. + +If F<ppport.h> was generated using the latest version of +C<Devel::PPPort> and is causing failure of this module, please +file a bug report using the CPAN Request Tracker at L<http://rt.cpan.org/>. + +Please include the following information: + +=over 4 + +=item 1. + +The complete output from running "perl -V" + +=item 2. + +This file. + +=item 3. + +The name and version of the module you were trying to build. + +=item 4. + +A full log of the build that failed. + +=item 5. + +Any other information that you think could be relevant. + +=back + +For the latest version of this code, please get the C<Devel::PPPort> +module from CPAN. + +=head1 COPYRIGHT + +Version 3.x, Copyright (c) 2004-2009, Marcus Holland-Moritz. + +Version 2.x, Copyright (C) 2001, Paul Marquess. + +Version 1.x, Copyright (C) 1999, Kenneth Albanowski. + +This program is free software; you can redistribute it and/or +modify it under the same terms as Perl itself. + +=head1 SEE ALSO + +See L<Devel::PPPort>. + +=cut + |
