54 This version of F<ppport.h> is designed to support operation with Perl
55 installations back to 5.003, and has been tested up to 5.9.3.
61 Display a brief usage summary.
63 =head2 --patch=I<file>
65 If this option is given, a single patch file will be created if
66 any changes are suggested. This requires a working diff program
67 to be installed on your system.
69 =head2 --copy=I<suffix>
71 If this option is given, a copy of each file will be saved with
72 the given suffix that contains the suggested changes. This does
73 not require any external programs.
75 If neither C<--patch> or C<--copy> are given, the default is to
76 simply print the diffs for each file. This requires either
77 C<Text::Diff> or a C<diff> program to be installed.
79 =head2 --diff=I<program>
81 Manually set the diff program and options to use. The default
82 is to use C<Text::Diff>, when installed, and output unified
85 =head2 --compat-version=I<version>
87 Tell F<ppport.h> to check for compatibility with the given
88 Perl version. The default is to check for compatibility with Perl
89 version 5.003. You can use this option to reduce the output
90 of F<ppport.h> if you intend to be backward compatible only
91 up to a certain Perl version.
95 Usually, F<ppport.h> will detect C++ style comments and
96 replace them with C style comments for portability reasons.
97 Using this option instructs F<ppport.h> to leave C++
102 Be quiet. Don't print anything except fatal errors.
106 Don't output any diagnostic messages. Only portability
107 alerts will be printed.
111 Don't output any hints. Hints often contain useful portability
116 Don't suggest any changes. Only give diagnostic output and hints
117 unless these are also deactivated.
121 Don't filter the list of input files. By default, files not looking
122 like source code (i.e. not *.xs, *.c, *.cc, *.cpp or *.h) are skipped.
124 =head2 --list-provided
126 Lists the API elements for which compatibility is provided by
127 F<ppport.h>. Also lists if it must be explicitly requested,
128 if it has dependencies, and if there are hints for it.
130 =head2 --list-unsupported
132 Lists the API elements that are known not to be supported by
133 F<ppport.h> and below which version of Perl they probably
134 won't be available or work.
136 =head2 --api-info=I<name>
138 Show portability information for API elements matching I<name>.
139 If I<name> is surrounded by slashes, it is interpreted as a regular
144 In order for a Perl extension (XS) module to be as portable as possible
145 across differing versions of Perl itself, certain steps need to be taken.
151 Including this header is the first major one. This alone will give you
152 access to a large part of the Perl API that hasn't been available in
153 earlier Perl releases. Use
155 perl ppport.h --list-provided
157 to see which API elements are provided by ppport.h.
161 You should avoid using deprecated parts of the API. For example, using
162 global Perl variables without the C<PL_> prefix is deprecated. Also,
163 some API functions used to have a C<perl_> prefix. Using this form is
164 also deprecated. You can safely use the supported API, as F<ppport.h>
165 will provide wrappers for older Perl versions.
169 If you use one of a few functions that were not present in earlier
170 versions of Perl, and that can't be provided using a macro, you have
171 to explicitly request support for these functions by adding one or
172 more C<#define>s in your source code before the inclusion of F<ppport.h>.
174 These functions will be marked C<explicit> in the list shown by
177 Depending on whether you module has a single or multiple files that
178 use such functions, you want either C<static> or global variants.
180 For a C<static> function, use:
182 #define NEED_function
184 For a global function, use:
186 #define NEED_function_GLOBAL
188 Note that you mustn't have more than one global request for one
189 function in your project.

209 To avoid namespace conflicts, you can change the namespace of the
210 explicitly exported functions using the C<DPPP_NAMESPACE> macro.
211 Just C<#define> the macro before including C<ppport.h>:
213 #define DPPP_NAMESPACE MyOwnNamespace_
216 The default namespace is C<DPPP_>.
220 The good thing is that most of the above can be checked by running
221 F<ppport.h> on your source code. See the next section for
226 To verify whether F<ppport.h> is needed for your module, whether you
227 should make any changes to your code, and whether any special defines
228 should be used, F<ppport.h> can be run as a Perl script to check your
229 source code. Simply say:
233 The result will usually be a list of patches suggesting changes
234 that should at least be acceptable, if not necessarily the most
235 efficient solution, or a fix for all possible problems.
237 If you know that your XS module uses features only available in
238 newer Perl releases, if you're aware that it uses C++ comments,
239 and if you want all suggestions as a single patch file, you could
240 use something like this:
242 perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff
244 If you only want your code to be scanned without any suggestions
247 perl ppport.h --nochanges
249 You can specify a different C<diff> program or options, using
250 the C<--diff> option:
252 perl ppport.h --diff='diff -C 10'
254 This would output context diffs with 10 lines of context.
256 To display portability information for the C<newSVpvn> function,
259 perl ppport.h --api-info=newSVpvn
261 Since the argument to C<--api-info> can be a regular expression,
264 perl ppport.h --api-info=/_nomg$/
266 to display portability information for all C<_nomg> functions or
268 perl ppport.h --api-info=/./
270 to display information for all known API elements.
274 If this version of F<ppport.h> is causing failure during
275 the compilation of this module, please check if newer versions
276 of either this module or C<Devel::PPPort> are available on CPAN
277 before sending a bug report.
279 If F<ppport.h> was generated using the latest version of
280 C<Devel::PPPort> and is causing failure of this module, please
281 file a bug report using the CPAN Request Tracker at L<http://rt.cpan.org/>.
283 Please include the following information:
289 The complete output from running "perl -V"
297 The name and version of the module you were trying to build.
301 A full log of the build that failed.
