Code Editor : h2xs
#!/usr/bin/perl eval 'exec /usr/bin/perl -S $0 ${1+"$@"}' if $running_under_some_shell; BEGIN { pop @INC if $INC[-1] eq '.' } use warnings; =head1 NAME h2xs - convert .h C header files to Perl extensions =head1 SYNOPSIS B<h2xs> [B<OPTIONS> ...] [headerfile ... [extra_libraries]] B<h2xs> B<-h>|B<-?>|B<--help> =head1 DESCRIPTION I<h2xs> builds a Perl extension from C header files. The extension will include functions which can be used to retrieve the value of any #define statement which was in the C header files. The I<module_name> will be used for the name of the extension. If module_name is not supplied then the name of the first header file will be used, with the first character capitalized. If the extension might need extra libraries, they should be included here. The extension Makefile.PL will take care of checking whether the libraries actually exist and how they should be loaded. The extra libraries should be specified in the form -lm -lposix, etc, just as on the cc command line. By default, the Makefile.PL will search through the library path determined by Configure. That path can be augmented by including arguments of the form B<-L/another/library/path> in the extra-libraries argument. In spite of its name, I<h2xs> may also be used to create a skeleton pure Perl module. See the B<-X> option. =head1 OPTIONS =over 5 =item B<-A>, B<--omit-autoload> Omit all autoload facilities. This is the same as B<-c> but also removes the S<C<use AutoLoader>> statement from the .pm file. =item B<-B>, B<--beta-version> Use an alpha/beta style version number. Causes version number to be "0.00_01" unless B<-v> is specified. =item B<-C>, B<--omit-changes> Omits creation of the F<Changes> file, and adds a HISTORY section to the POD template. =item B<-F>, B<--cpp-flags>=I<addflags> Additional flags to specify to C preprocessor when scanning header for function declarations. Writes these options in the generated F<Makefile.PL> too. =item B<-M>, B<--func-mask>=I<regular expression> selects functions/macros to process. =item B<-O>, B<--overwrite-ok> Allows a pre-existing extension directory to be overwritten. =item B<-P>, B<--omit-pod> Omit the autogenerated stub POD section. =item B<-X>, B<--omit-XS> Omit the XS portion. Used to generate a skeleton pure Perl module. C<-c> and C<-f> are implicitly enabled. =item B<-a>, B<--gen-accessors> Generate an accessor method for each element of structs and unions. The generated methods are named after the element name; will return the current value of the element if called without additional arguments; and will set the element to the supplied value (and return the new value) if called with an additional argument. Embedded structures and unions are returned as a pointer rather than the complete structure, to facilitate chained calls. These methods all apply to the Ptr type for the structure; additionally two methods are constructed for the structure type itself, C<_to_ptr> which returns a Ptr type pointing to the same structure, and a C<new> method to construct and return a new structure, initialised to zeroes. =item B<-b>, B<--compat-version>=I<version> Generates a .pm file which is backwards compatible with the specified perl version. For versions < 5.6.0, the changes are. - no use of 'our' (uses 'use vars' instead) - no 'use warnings' Specifying a compatibility version higher than the version of perl you are using to run h2xs will have no effect. If unspecified h2xs will default to compatibility with the version of perl you are using to run h2xs. =item B<-c>, B<--omit-constant> Omit C<constant()> from the .xs file and corresponding specialised C<AUTOLOAD> from the .pm file. =item B<-d>, B<--debugging> Turn on debugging messages. =item B<-e>, B<--omit-enums>=[I<regular expression>] If I<regular expression> is not given, skip all constants that are defined in a C enumeration. Otherwise skip only those constants that are defined in an enum whose name matches I<regular expression>. Since I<regular expression> is optional, make sure that this switch is followed by at least one other switch if you omit I<regular expression> and have some pending arguments such as header-file names. This is ok: h2xs -e -n Module::Foo foo.h This is not ok: h2xs -n Module::Foo -e foo.h In the latter, foo.h is taken as I<regular expression>. =item B<-f>, B<--force> Allows an extension to be created for a header even if that header is not found in standard include directories. =item B<-g>, B<--global> Include code for safely storing static data in the .xs file. Extensions that do no make use of static data can ignore this option. =item B<-h>, B<-?>, B<--help> Print the usage, help and version for this h2xs and exit. =item B<-k>, B<--omit-const-func> For function arguments declared as C<const>, omit the const attribute in the generated XS code. =item B<-m>, B<--gen-tied-var> B<Experimental>: for each variable declared in the header file(s), declare a perl variable of the same name magically tied to the C variable. =item B<-n>, B<--name>=I<module_name> Specifies a name to be used for the extension, e.g., S<-n RPC::DCE> =item B<-o>, B<--opaque-re>=I<regular expression> Use "opaque" data type for the C types matched by the regular expression, even if these types are C<typedef>-equivalent to types from typemaps. Should not be used without B<-x>. This may be useful since, say, types which are C<typedef>-equivalent to integers may represent OS-related handles, and one may want to work with these handles in OO-way, as in C<$handle-E<gt>do_something()>. Use C<-o .> if you want to handle all the C<typedef>ed types as opaque types. The type-to-match is whitewashed (except for commas, which have no whitespace before them, and multiple C<*> which have no whitespace between them). =item B<-p>, B<--remove-prefix>=I<prefix> Specify a prefix which should be removed from the Perl function names, e.g., S<-p sec_rgy_> This sets up the XS B<PREFIX> keyword and removes the prefix from functions that are autoloaded via the C<constant()> mechanism. =item B<-s>, B<--const-subs>=I<sub1,sub2> Create a perl subroutine for the specified macros rather than autoload with the constant() subroutine. These macros are assumed to have a return type of B<char *>, e.g., S<-s sec_rgy_wildcard_name,sec_rgy_wildcard_sid>. =item B<-t>, B<--default-type>=I<type> Specify the internal type that the constant() mechanism uses for macros. The default is IV (signed integer). Currently all macros found during the header scanning process will be assumed to have this type. Future versions of C<h2xs> may gain the ability to make educated guesses. =item B<--use-new-tests> When B<--compat-version> (B<-b>) is present the generated tests will use C<Test::More> rather than C<Test> which is the default for versions before 5.6.2. C<Test::More> will be added to PREREQ_PM in the generated C<Makefile.PL>. =item B<--use-old-tests> Will force the generation of test code that uses the older C<Test> module. =item B<--skip-exporter> Do not use C<Exporter> and/or export any symbol. =item B<--skip-ppport> Do not use C<Devel::PPPort>: no portability to older version. =item B<--skip-autoloader> Do not use the module C<AutoLoader>; but keep the constant() function and C<sub AUTOLOAD> for constants. =item B<--skip-strict> Do not use the pragma C<strict>. =item B<--skip-warnings> Do not use the pragma C<warnings>. =item B<-v>, B<--version>=I<version> Specify a version number for this extension. This version number is added to the templates. The default is 0.01, or 0.00_01 if C<-B> is specified. The version specified should be numeric. =item B<-x>, B<--autogen-xsubs> Automatically generate XSUBs basing on function declarations in the header file. The package C<C::Scan> should be installed. If this option is specified, the name of the header file may look like C<NAME1,NAME2>. In this case NAME1 is used instead of the specified string, but XSUBs are emitted only for the declarations included from file NAME2. Note that some types of arguments/return-values for functions may result in XSUB-declarations/typemap-entries which need hand-editing. Such may be objects which cannot be converted from/to a pointer (like C<long long>), pointers to functions, or arrays. See also the section on L<LIMITATIONS of B<-x>>. =back =head1 EXAMPLES # Default behavior, extension is Rusers h2xs rpcsvc/rusers # Same, but extension is RUSERS h2xs -n RUSERS rpcsvc/rusers # Extension is rpcsvc::rusers.

How to create an extension which makes this functionality accessible in Perl? The example below assumes that the header files are F<interface_simple.h> and I<interface_hairy.h>, and you want the perl module be named as C<Ext::Ension>. If you need some preprocessor directives and/or linking with external libraries, see the flags C<-F>, C<-L> and C<-l> in L<"OPTIONS">. =over =item Find the directory name Start with a dummy run of h2xs: h2xs -Afn Ext::Ension The only purpose of this step is to create the needed directories, and let you know the names of these directories. From the output you can see that the directory for the extension is F<Ext/Ension>. =item Copy C files Copy your header files and C files to this directory F<Ext/Ension>. =item Create the extension Run h2xs, overwriting older autogenerated files: h2xs -Oxan Ext::Ension interface_simple.h interface_hairy.h h2xs looks for header files I<after> changing to the extension directory, so it will find your header files OK. =item Archive and test As usual, run cd Ext/Ension perl Makefile.PL make dist make make test =item Hints It is important to do C<make dist> as early as possible. This way you can easily merge(1) your changes to autogenerated files if you decide to edit your C<.h> files and rerun h2xs. Do not forget to edit the documentation in the generated F<.pm> file. Consider the autogenerated files as skeletons only, you may invent better interfaces than what h2xs could guess. Consider this section as a guideline only, some other options of h2xs may better suit your needs. =back =head1 ENVIRONMENT No environment variables are used. =head1 AUTHOR Larry Wall and others =head1 SEE ALSO L<perl>, L<perlxstut>, L<ExtUtils::MakeMaker>, and L<AutoLoader>. =head1 DIAGNOSTICS The usual warnings if it cannot read or write the files involved. =head1 LIMITATIONS of B<-x> F<h2xs> would not distinguish whether an argument to a C function which is of the form, say, C<int *>, is an input, output, or input/output parameter. In particular, argument declarations of the form int foo(n) int *n should be better rewritten as int foo(n) int &n if C<n> is an input parameter. Additionally, F<h2xs> has no facilities to intuit that a function int foo(addr,l) char *addr int l takes a pair of address and length of data at this address, so it is better to rewrite this function as int foo(sv) SV *addr PREINIT: STRLEN len; char *s; CODE: s = SvPV(sv,len); RETVAL = foo(s, len); OUTPUT: RETVAL or alternately static int my_foo(SV *sv) { STRLEN len; char *s = SvPV(sv,len); return foo(s, len); } MODULE = foo PACKAGE = foo PREFIX = my_ int foo(sv) SV *sv See L<perlxs> and L<perlxstut> for additional details. =cut # ' # Grr use strict; my( $H2XS_VERSION ) = ' $Revision: 1.23 $ ' =~ /\$Revision:\s+([^\s]+)/; my $TEMPLATE_VERSION = '0.01'; my @ARGS = @ARGV; my $compat_version = $]; use Getopt::Long; use Config; use Text::Wrap; $Text::Wrap::huge = 'overflow'; $Text::Wrap::columns = 80; use ExtUtils::Constant qw (WriteConstants WriteMakefileSnippet autoload); use File::Compare; use File::Path; sub usage { warn "@_\n" if @_; die <<EOFUSAGE; h2xs [OPTIONS ... ] [headerfile [extra_libraries]] version: $H2XS_VERSION OPTIONS: -A, --omit-autoload Omit all autoloading facilities (implies -c). -B, --beta-version Use beta \$VERSION of 0.00_01 (ignored if -v). -C, --omit-changes Omit creating the Changes file, add HISTORY heading to stub POD. -F, --cpp-flags Additional flags for C preprocessor/compile. -M, --func-mask Mask to select C functions/macros (default is select all). -O, --overwrite-ok Allow overwriting of a pre-existing extension directory. -P, --omit-pod Omit the stub POD section. -X, --omit-XS Omit the XS portion (implies both -c and -f). -a, --gen-accessors Generate get/set accessors for struct and union members (used with -x). -b, --compat-version Specify a perl version to be backwards compatible with. -c, --omit-constant Omit the constant() function and specialised AUTOLOAD from the XS file. -d, --debugging Turn on debugging messages. -e, --omit-enums Omit constants from enums in the constant() function.
