41 | ||
42 | h2xs - convert .h C header files to Perl extensions | |
43 | ||
44 | =head1 SYNOPSIS | |

50 | =head1 DESCRIPTION | |
51 | ||
a887ff11 BS |
52 | I<h2xs> builds a Perl extension from C header files. The extension |
53 | will include functions which can be used to retrieve the value of any | |
54 | #define statement which was in the C header files. | |
3edbfbe5 TB |
55 | |
56 | The I<module_name> will be used for the name of the extension. If | |
a887ff11 BS |
57 | module_name is not supplied then the name of the first header file |
58 | will be used, with the first character capitalized. | |
3edbfbe5 TB |
59 | |
60 | If the extension might need extra libraries, they should be included | |
61 | here. The extension Makefile.PL will take care of checking whether | |
9cacc32e JH |
62 | the libraries actually exist and how they should be loaded. The extra |
63 | libraries should be specified in the form -lm -lposix, etc, just as on | |
64 | the cc command line. By default, the Makefile.PL will search through | |
65 | the library path determined by Configure. That path can be augmented | |
66 | by including arguments of the form B<-L/another/library/path> in the | |
67 | extra-libraries argument. | |

75 | Omit all autoload facilities. This is the same as B<-c> but also |
76 | removes the S<C<use AutoLoader>> statement from the .pm file. | |
3edbfbe5 | 77 | |

c0f8b9cd GS |
79 | |
80 | Omits creation of the F<Changes> file, and adds a HISTORY section to | |
81 | the POD template. | |
82 | ||
4d2d0db2 | 83 | =item B<-F>, B<--cpp-flags>=I<addflags> |
b73edd97 | 84 | |
85 | Additional flags to specify to C preprocessor when scanning header for | |
dcb5229a IZ |
86 | function declarations. Writes these options in the generated F<Makefile.PL> |
87 | too. | |
ddf6bed1 | 88 | |
4d2d0db2 | 89 | =item B<-M>, B<--func-mask>=I<regular expression> |

b73edd97 | 92 | |
4d2d0db2 | 93 | =item B<-O>, B<--overwrite-ok> |
2920c5d2 | 94 | |
95 | Allows a pre-existing extension directory to be overwritten. | |
96 | ||
4d2d0db2 | 97 | =item B<-P>, B<--omit-pod> |
3edbfbe5 | 98 | |
f508c652 | 99 | Omit the autogenerated stub POD section. |

4d2d0db2 | 101 | =item B<-X>, B<--omit-XS> |
b73edd97 | 102 | |
103 | Omit the XS portion. Used to generate templates for a module which is not | |
9ef261b5 | 104 | XS-based. C<-c> and C<-f> are implicitly enabled. |

4d2d0db2 | 106 | =item B<-a>, B<--gen-accessors> |
7c1d48a5 GS |
107 | |
108 | Generate an accessor method for each element of structs and unions. The | |
109 | generated methods are named after the element name; will return the current | |
110 | value of the element if called without additional arguments; and will set | |
32fb2b78 GS |
111 | the element to the supplied value (and return the new value) if called with |
112 | an additional argument. Embedded structures and unions are returned as a | |
113 | pointer rather than the complete structure, to facilitate chained calls. | |
114 | ||
115 | These methods all apply to the Ptr type for the structure; additionally | |
116 | two methods are constructed for the structure type itself, C<_to_ptr> | |
117 | which returns a Ptr type pointing to the same structure, and a C<new> | |
118 | method to construct and return a new structure, initialised to zeroes. | |
7c1d48a5 | 119 | |

af6c647e NC |
121 | |
122 | Generates a .pm file which is backwards compatible with the specified | |
123 | perl version. | |
124 | ||
125 | For versions < 5.6.0, the changes are. | |
126 | - no use of 'our' (uses 'use vars' instead) | |
127 | - no 'use warnings' | |
128 | ||
129 | Specifying a compatibility version higher than the version of perl you | |
3e6e4ea8 NC |
130 | are using to run h2xs will have no effect. If unspecified h2xs will default |
131 | to compatibility with the version of perl you are using to run h2xs. | |
af6c647e | 132 | |
4d2d0db2 | 133 | =item B<-c>, B<--omit-constant> |
3edbfbe5 TB |
134 | |
135 | Omit C<constant()> from the .xs file and corresponding specialised | |
136 | C<AUTOLOAD> from the .pm file. | |
137 | ||
4d2d0db2 | 138 | =item B<-d>, B<--debugging> |

4d2d0db2 | 142 | =item B<-f>, B<--force> |
3edbfbe5 | 143 | |
f508c652 | 144 | Allows an extension to be created for a header even if that header is |
ddf6bed1 | 145 | not found in standard include directories. |
f508c652 | 146 | |

149 | Include code for safely storing static data in the .xs file. | |
150 | Extensions that do no make use of static data can ignore this option. | |
151 | ||
4d2d0db2 | 152 | =item B<-h>, B<-?>, B<--help> |
f508c652 | 153 | |

155 | ||
4d2d0db2 | 156 | =item B<-k>, B<--omit-const-func> |
32fb2b78 GS |
157 | |
158 | For function arguments declared as C<const>, omit the const attribute in the | |
159 | generated XS code. | |

165 | ||
4d2d0db2 | 166 | =item B<-n>, B<--name>=I<module_name> |
f508c652 | 167 | |
168 | Specifies a name to be used for the extension, e.g., S<-n RPC::DCE> | |
169 | ||
4d2d0db2 | 170 | =item B<-o>, B<--opaque-re>=I<regular expression> |
ddf6bed1 IZ |
171 | |
172 | Use "opaque" data type for the C types matched by the regular | |
173 | expression, even if these types are C<typedef>-equivalent to types | |
174 | from typemaps. Should not be used without B<-x>. | |
175 | ||
176 | This may be useful since, say, types which are C<typedef>-equivalent | |
177 | to integers may represent OS-related handles, and one may want to work | |
178 | with these handles in OO-way, as in C<$handle-E<gt>do_something()>. | |
9cacc32e JH |
179 | Use C<-o .> if you want to handle all the C<typedef>ed types as opaque |
180 | types. | |
ddf6bed1 IZ |
181 | |
182 | The type-to-match is whitewashed (except for commas, which have no | |
183 | whitespace before them, and multiple C<*> which have no whitespace | |
184 | between them). | |
185 | ||
4d2d0db2 | 186 | =item B<-p>, B<--remove-prefix>=I<prefix> |
ead2a595 | 187 | |
9cacc32e JH |
188 | Specify a prefix which should be removed from the Perl function names, |
189 | e.g., S<-p sec_rgy_> This sets up the XS B<PREFIX> keyword and removes | |
190 | the prefix from functions that are autoloaded via the C<constant()> | |
191 | mechanism. | |
ead2a595 | 192 | |
4d2d0db2 | 193 | =item B<-s>, B<--const-subs>=I<sub1,sub2> |
ead2a595 | 194 | |
9cacc32e JH |
195 | Create a perl subroutine for the specified macros rather than autoload |
196 | with the constant() subroutine. These macros are assumed to have a | |
197 | return type of B<char *>, e.g., | |
198 | S<-s sec_rgy_wildcard_name,sec_rgy_wildcard_sid>. | |
ead2a595 | 199 | |
4d2d0db2 | 200 | =item B<-t>, B<--default-type>=I<type> |
af6c647e NC |
201 | |
202 | Specify the internal type that the constant() mechanism uses for macros. | |
203 | The default is IV (signed integer). Currently all macros found during the | |
204 | header scanning process will be assumed to have this type. Future versions | |
205 | of C<h2xs> may gain the ability to make educated guesses. | |
206 | ||
11946041 JS |
207 | =item B<--use-new-tests> |
208 | ||
209 | When B<--compat-version> (B<-b>) is present the generated tests will use | |
210 | C<Test::More> rather then C<Test> which is the default for versions before | |
211 | 5.7.2 . C<Test::More> will be added to PREREQ_PM in the generated | |
212 | C<Makefile.PL>. | |
213 | ||
214 | =item B<--use-old-tests> | |
215 | ||
216 | Will force the generation of test code that uses the older C<Test> module. | |
217 | ||
dcb5229a IZ |
218 | =item B<--skip-exporter> |
219 | ||
220 | Do not use C<Exporter> and/or export any symbol. | |
221 | ||
222 | =item B<--skip-ppport> | |
223 | ||
224 | Do not use C<Devel::PPPort>: no portability to older version. | |
225 | ||
226 | =item B<--skip-autoloader> | |
227 | ||
228 | Do not use the module C<AutoLoader>; but keep the constant() function | |
229 | and C<sub AUTOLOAD> for constants. | |
230 | ||
231 | =item B<--skip-strict> | |
232 | ||
233 | Do not use the pragma C<strict>. | |
234 | ||
235 | =item B<--skip-warnings> | |
236 | ||
237 | Do not use the pragma C<warnings>. | |
238 | ||
4d2d0db2 | 239 | =item B<-v>, B<--version>=I<version> |
f508c652 | 240 | |
241 | Specify a version number for this extension. This version number is added | |
242 | to the templates. The default is 0.01. | |
3edbfbe5 | 243 | |
4d2d0db2 | 244 | =item B<-x>, B<--autogen-xsubs> |
760ac839 LW |
245 | |
246 | Automatically generate XSUBs basing on function declarations in the | |
247 | header file. The package C<C::Scan> should be installed. If this | |
248 | option is specified, the name of the header file may look like | |
9cacc32e JH |
249 | C<NAME1,NAME2>. In this case NAME1 is used instead of the specified |
250 | string, but XSUBs are emitted only for the declarations included from | |
251 | file NAME2. | |
760ac839 | 252 | |
5273d82d IZ |
253 | Note that some types of arguments/return-values for functions may |
254 | result in XSUB-declarations/typemap-entries which need | |
255 | hand-editing. Such may be objects which cannot be converted from/to a | |
ddf6bed1 IZ |
256 | pointer (like C<long long>), pointers to functions, or arrays. See |
257 | also the section on L<LIMITATIONS of B<-x>>. | |

316 | =head2 Extension based on F<.h> and F<.c> files |
317 | ||
318 | Suppose that you have some C files implementing some functionality, | |
319 | and the corresponding header files. How to create an extension which | |
320 | makes this functionality accessable in Perl? The example below | |
321 | assumes that the header files are F<interface_simple.h> and | |
322 | I<interface_hairy.h>, and you want the perl module be named as | |
323 | C<Ext::Ension>. If you need some preprocessor directives and/or | |
324 | linking with external libraries, see the flags C<-F>, C<-L> and C<-l> | |
325 | in L<"OPTIONS">. | |
326 | ||
327 | =over | |
328 | ||
329 | =item Find the directory name | |
330 | ||
331 | Start with a dummy run of h2xs: | |
332 | ||
333 | h2xs -Afn Ext::Ension | |
334 | ||
335 | The only purpose of this step is to create the needed directories, and | |
336 | let you know the names of these directories. From the output you can | |
337 | see that the directory for the extension is F<Ext/Ension>. | |
338 | ||
339 | =item Copy C files | |
340 | ||
341 | Copy your header files and C files to this directory F<Ext/Ension>. | |
342 | ||
343 | =item Create the extension | |
344 | ||
345 | Run h2xs, overwriting older autogenerated files: | |
346 | ||
347 | h2xs -Oxan Ext::Ension interface_simple.h interface_hairy.h | |
348 | ||
349 | h2xs looks for header files I<after> changing to the extension | |
350 | directory, so it will find your header files OK. | |
351 | ||
352 | =item Archive and test | |
353 | ||
354 | As usual, run | |
355 | ||
356 | cd Ext/Ension | |
357 | perl Makefile.PL | |
358 | make dist | |
359 | make | |
360 | make test | |
361 | ||
362 | =item Hints | |
363 | ||
364 | It is important to do C<make dist> as early as possible. This way you | |
365 | can easily merge(1) your changes to autogenerated files if you decide | |
366 | to edit your C<.h> files and rerun h2xs. | |
367 | ||
368 | Do not forget to edit the documentation in the generated F<.pm> file. | |
369 | ||
370 | Consider the autogenerated files as skeletons only, you may invent | |
371 | better interfaces than what h2xs could guess. | |
372 | ||
373 | Consider this section as a guideline only, some other options of h2xs | |
374 | may better suit your needs. | |

395 | ||
396 | F<h2xs> would not distinguish whether an argument to a C function | |
397 | which is of the form, say, C<int *>, is an input, output, or | |
398 | input/output parameter. In particular, argument declarations of the | |
399 | form | |
400 | ||
401 | int | |
402 | foo(n) | |
403 | int *n | |
404 | ||
405 | should be better rewritten as | |
406 | ||
407 | int | |
408 | foo(n) | |
409 | int &n | |
410 | ||
411 | if C<n> is an input parameter. | |
412 | ||
413 | Additionally, F<h2xs> has no facilities to intuit that a function | |
414 | ||
415 | int | |
416 | foo(addr,l) | |
417 | char *addr | |
418 | int l | |
419 | ||
420 | takes a pair of address and length of data at this address, so it is better | |

1221 | # This should be the abstract for $module. | |
1222 | # The abstract is used when making PPD (Perl Package Description) files. | |
1223 | # If you don't want an ABSTRACT you should also edit Makefile.PL to | |
1224 | # remove the ABSTRACT_FROM option. | |
1225 | # | |

1227 | # | |
7aff18a2 | 1228 | #Stub documentation for $module, created by h2xs. It looks like the |
f508c652 | 1229 | #author of the extension was negligent enough to leave the stub |
1230 | #unedited. | |
1231 | # | |
1232 | #Blah blah blah. | |
