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 prefix is deprecated. Also, +some API functions used to have a C prefix. Using this form is +also deprecated. You can safely use the supported API, as F +will provide wrappers for older Perl versions. + +=item * + +If you use one of a few functions 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. + +These functions will be marked C in the list shown by +C<--list-provided>. + +Depending on whether you module has a single or multiple files that +use such functions, you want either C or global variants. + +For a C function, use: + + #define NEED_function + +For a global function, use: + + #define NEED_function_GLOBAL + +Note that you mustn't have more than one global request for one +function in your project. + + Function Static Request Global Request + ----------------------------------------------------------------------------------------- + eval_pv() NEED_eval_pv NEED_eval_pv_GLOBAL + grok_bin() NEED_grok_bin NEED_grok_bin_GLOBAL + grok_hex() NEED_grok_hex NEED_grok_hex_GLOBAL + grok_number() NEED_grok_number NEED_grok_number_GLOBAL + grok_numeric_radix() NEED_grok_numeric_radix NEED_grok_numeric_radix_GLOBAL + grok_oct() NEED_grok_oct NEED_grok_oct_GLOBAL + newCONSTSUB() NEED_newCONSTSUB NEED_newCONSTSUB_GLOBAL + newRV_noinc() NEED_newRV_noinc NEED_newRV_noinc_GLOBAL + sv_2pv_nolen() NEED_sv_2pv_nolen NEED_sv_2pv_nolen_GLOBAL + sv_2pvbyte() NEED_sv_2pvbyte NEED_sv_2pvbyte_GLOBAL + sv_catpvf_mg() NEED_sv_catpvf_mg NEED_sv_catpvf_mg_GLOBAL + sv_catpvf_mg_nocontext() NEED_sv_catpvf_mg_nocontext NEED_sv_catpvf_mg_nocontext_GLOBAL + sv_setpvf_mg() NEED_sv_setpvf_mg NEED_sv_setpvf_mg_GLOBAL + sv_setpvf_mg_nocontext() NEED_sv_setpvf_mg_nocontext NEED_sv_setpvf_mg_nocontext_GLOBAL + vnewSVpvf() NEED_vnewSVpvf NEED_vnewSVpvf_GLOBAL + +To avoid namespace conflicts, you can change the namespace of the +explicitly exported functions using the C macro. +Just C<#define> the macro before including C: + + #define DPPP_NAMESPACE MyOwnNamespace_ + #include "ppport.h" + +The default namespace is C. + +=back + +The good thing is that most of the above can be checked by running +F on 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 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. + +=head1 BUGS + +If this version of F is causing failure during +the compilation of this module, please check if newer versions +of either this module or C are available on CPAN +before sending a bug report. + +If F was generated using the latest version of +C and is causing failure of this module, please +file a bug report using the CPAN Request Tracker at L. + +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 +module from CPAN. + +=head1 COPYRIGHT + +Version 3.x, Copyright (c) 2004, 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. + +=cut + +use strict; + +my %opt = ( + quiet => 0, + diag => 1, + hints => 1, + changes => 1, + cplusplus => 0, +); + +my($ppport) = $0 =~ /([\w.]+)$/; +my $LF = '(?:\r\n|[\r\n])'; # line feed +my $HS = "[ \t]"; # horizontal whitespace + +eval { + require Getopt::Long; + Getopt::Long::GetOptions(\%opt, qw( + help quiet diag! hints! changes! cplusplus + patch=s copy=s diff=s compat-version=s + list-provided list-unsupported + )) or usage(); +}; + +if ($@ and grep /^-/, @ARGV) { + usage() if "@ARGV" =~ /^--?h(?:elp)?$/; + die "Getopt::Long not found.
