40 | =head1 NAME |
41 | |
42 | h2xs - convert .h C header files to Perl extensions |
43 | |
44 | =head1 SYNOPSIS |
45 | |
11946041 |
46 | B<h2xs> [B<OPTIONS> ...] [headerfile ... [extra_libraries]] |

50 | =head1 DESCRIPTION |
51 | |
a887ff11 |
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 |
55 | |
56 | The I<module_name> will be used for the name of the extension. If |
a887ff11 |
57 | module_name is not supplied then the name of the first header file |
58 | will be used, with the first character capitalized. |
3edbfbe5 |
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 |
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. |

72 | |
4d2d0db2 |
73 | =item B<-A>, B<--omit-autoload> |
3edbfbe5 |
74 | |
9cacc32e |
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 | |
9e4509e4 |
78 | =item B<-B>, B<--beta-version> |
79 | |
80 | Use an alpha/beta style version number. Causes version number to |
81 | be "0.00_01" unless B<-v> is specified. |
82 | |
4d2d0db2 |
83 | =item B<-C>, B<--omit-changes> |
c0f8b9cd |
84 | |
85 | Omits creation of the F<Changes> file, and adds a HISTORY section to |
86 | the POD template. |
87 | |
4d2d0db2 |
88 | =item B<-F>, B<--cpp-flags>=I<addflags> |
b73edd97 |
89 | |
90 | Additional flags to specify to C preprocessor when scanning header for |
dcb5229a |
91 | function declarations. Writes these options in the generated F<Makefile.PL> |
92 | too. |
ddf6bed1 |
93 | |
4d2d0db2 |
94 | =item B<-M>, B<--func-mask>=I<regular expression> |
ddf6bed1 |
95 | |
96 | selects functions/macros to process. |
b73edd97 |
97 | |
4d2d0db2 |
98 | =item B<-O>, B<--overwrite-ok> |
2920c5d2 |
99 | |
100 | Allows a pre-existing extension directory to be overwritten. |
101 | |
4d2d0db2 |
102 | =item B<-P>, B<--omit-pod> |
3edbfbe5 |
103 | |
f508c652 |
104 | Omit the autogenerated stub POD section. |
3edbfbe5 |
105 | |
4d2d0db2 |
106 | =item B<-X>, B<--omit-XS> |
b73edd97 |
107 | |
108 | Omit the XS portion. Used to generate templates for a module which is not |
9ef261b5 |
109 | XS-based. C<-c> and C<-f> are implicitly enabled. |
b73edd97 |
110 | |
4d2d0db2 |
111 | =item B<-a>, B<--gen-accessors> |
7c1d48a5 |
112 | |
113 | Generate an accessor method for each element of structs and unions. The |
114 | generated methods are named after the element name; will return the current |
115 | value of the element if called without additional arguments; and will set |
32fb2b78 |
116 | the element to the supplied value (and return the new value) if called with |
117 | an additional argument. Embedded structures and unions are returned as a |
118 | pointer rather than the complete structure, to facilitate chained calls. |
119 | |
120 | These methods all apply to the Ptr type for the structure; additionally |
121 | two methods are constructed for the structure type itself, C<_to_ptr> |
122 | which returns a Ptr type pointing to the same structure, and a C<new> |
123 | method to construct and return a new structure, initialised to zeroes. |
7c1d48a5 |
124 | |
4d2d0db2 |
125 | =item B<-b>, B<--compat-version>=I<version> |
af6c647e |
126 | |
127 | Generates a .pm file which is backwards compatible with the specified |
128 | perl version. |
129 | |
130 | For versions < 5.6.0, the changes are. |
131 | - no use of 'our' (uses 'use vars' instead) |
132 | - no 'use warnings' |
133 | |
134 | Specifying a compatibility version higher than the version of perl you |
3e6e4ea8 |
135 | are using to run h2xs will have no effect. If unspecified h2xs will default |
136 | to compatibility with the version of perl you are using to run h2xs. |
af6c647e |
137 | |
4d2d0db2 |
138 | =item B<-c>, B<--omit-constant> |
3edbfbe5 |
139 | |
140 | Omit C<constant()> from the .xs file and corresponding specialised |
141 | C<AUTOLOAD> from the .pm file. |
142 | |
4d2d0db2 |
143 | =item B<-d>, B<--debugging> |
b73edd97 |
144 | |
145 | Turn on debugging messages. |
146 | |
4d2d0db2 |
147 | =item B<-f>, B<--force> |
3edbfbe5 |
148 | |
f508c652 |
149 | Allows an extension to be created for a header even if that header is |
ddf6bed1 |
150 | not found in standard include directories. |
f508c652 |
151 | |
e255a1c9 |
152 | =item B<-g>, B<--global> |
153 | |
154 | Include code for safely storing static data in the .xs file. |
155 | Extensions that do no make use of static data can ignore this option. |
156 | |
4d2d0db2 |
157 | =item B<-h>, B<-?>, B<--help> |
f508c652 |
158 | |
159 | Print the usage, help and version for this h2xs and exit. |
160 | |
4d2d0db2 |
161 | =item B<-k>, B<--omit-const-func> |
32fb2b78 |
162 | |
163 | For function arguments declared as C<const>, omit the const attribute in the |
164 | generated XS code. |
165 | |
4d2d0db2 |
166 | =item B<-m>, B<--gen-tied-var> |
32fb2b78 |
167 | |
168 | B<Experimental>: for each variable declared in the header file(s), declare |
169 | a perl variable of the same name magically tied to the C variable. |
170 | |
4d2d0db2 |
171 | =item B<-n>, B<--name>=I<module_name> |
f508c652 |
172 | |
173 | Specifies a name to be used for the extension, e.g., S<-n RPC::DCE> |
174 | |
4d2d0db2 |
175 | =item B<-o>, B<--opaque-re>=I<regular expression> |
ddf6bed1 |
176 | |
177 | Use "opaque" data type for the C types matched by the regular |
178 | expression, even if these types are C<typedef>-equivalent to types |
179 | from typemaps. Should not be used without B<-x>. |
180 | |
181 | This may be useful since, say, types which are C<typedef>-equivalent |
182 | to integers may represent OS-related handles, and one may want to work |
183 | with these handles in OO-way, as in C<$handle-E<gt>do_something()>. |
9cacc32e |
184 | Use C<-o .> if you want to handle all the C<typedef>ed types as opaque |
185 | types. |
ddf6bed1 |
186 | |
187 | The type-to-match is whitewashed (except for commas, which have no |
188 | whitespace before them, and multiple C<*> which have no whitespace |
189 | between them). |
190 | |
4d2d0db2 |
191 | =item B<-p>, B<--remove-prefix>=I<prefix> |
ead2a595 |
192 | |
9cacc32e |
193 | Specify a prefix which should be removed from the Perl function names, |
194 | e.g., S<-p sec_rgy_> This sets up the XS B<PREFIX> keyword and removes |
195 | the prefix from functions that are autoloaded via the C<constant()> |
196 | mechanism. |
ead2a595 |
197 | |
4d2d0db2 |
198 | =item B<-s>, B<--const-subs>=I<sub1,sub2> |
ead2a595 |
199 | |
9cacc32e |
200 | Create a perl subroutine for the specified macros rather than autoload |
201 | with the constant() subroutine. These macros are assumed to have a |
202 | return type of B<char *>, e.g., |
203 | S<-s sec_rgy_wildcard_name,sec_rgy_wildcard_sid>. |
ead2a595 |
204 | |
4d2d0db2 |
205 | =item B<-t>, B<--default-type>=I<type> |
af6c647e |
206 | |
207 | Specify the internal type that the constant() mechanism uses for macros. |
208 | The default is IV (signed integer). Currently all macros found during the |
209 | header scanning process will be assumed to have this type. Future versions |
210 | of C<h2xs> may gain the ability to make educated guesses. |
211 | |
11946041 |
212 | =item B<--use-new-tests> |
213 | |
214 | When B<--compat-version> (B<-b>) is present the generated tests will use |
9e4509e4 |
215 | C<Test::More> rather than C<Test> which is the default for versions before |
11946041 |
216 | 5.7.2 . C<Test::More> will be added to PREREQ_PM in the generated |
217 | C<Makefile.PL>. |
218 | |
219 | =item B<--use-old-tests> |
220 | |
221 | Will force the generation of test code that uses the older C<Test> module. |
222 | |
dcb5229a |
223 | =item B<--skip-exporter> |
224 | |
225 | Do not use C<Exporter> and/or export any symbol. |
226 | |
227 | =item B<--skip-ppport> |
228 | |
229 | Do not use C<Devel::PPPort>: no portability to older version. |
230 | |
231 | =item B<--skip-autoloader> |
232 | |
233 | Do not use the module C<AutoLoader>; but keep the constant() function |
234 | and C<sub AUTOLOAD> for constants. |
235 | |
236 | =item B<--skip-strict> |
237 | |
238 | Do not use the pragma C<strict>. |
239 | |
240 | =item B<--skip-warnings> |
241 | |
242 | Do not use the pragma C<warnings>. |
243 | |
4d2d0db2 |
244 | =item B<-v>, B<--version>=I<version> |
f508c652 |
245 | |
246 | Specify a version number for this extension. This version number is added |
9e4509e4 |
247 | to the templates. The default is 0.01, or 0.00_01 if C<-B> is specified. |
248 | The version specified should be numeric. |
3edbfbe5 |
249 | |
4d2d0db2 |
250 | =item B<-x>, B<--autogen-xsubs> |
760ac839 |
251 | |
252 | Automatically generate XSUBs basing on function declarations in the |
253 | header file. The package C<C::Scan> should be installed. If this |
254 | option is specified, the name of the header file may look like |
9cacc32e |
255 | C<NAME1,NAME2>. In this case NAME1 is used instead of the specified |
256 | string, but XSUBs are emitted only for the declarations included from |
257 | file NAME2. |
760ac839 |
258 | |
5273d82d |
259 | Note that some types of arguments/return-values for functions may |
260 | result in XSUB-declarations/typemap-entries which need |
261 | hand-editing. Such may be objects which cannot be converted from/to a |
ddf6bed1 |
262 | pointer (like C<long long>), pointers to functions, or arrays. See |
263 | also the section on L<LIMITATIONS of B<-x>>. |

322 | =head2 Extension based on F<.h> and F<.c> files |
323 | |
324 | Suppose that you have some C files implementing some functionality, |
325 | and the corresponding header files. How to create an extension which |
326 | makes this functionality accessable in Perl? The example below |
327 | assumes that the header files are F<interface_simple.h> and |
328 | I<interface_hairy.h>, and you want the perl module be named as |
329 | C<Ext::Ension>. If you need some preprocessor directives and/or |
330 | linking with external libraries, see the flags C<-F>, C<-L> and C<-l> |
331 | in L<"OPTIONS">. |
332 | |
333 | =over |
334 | |
335 | =item Find the directory name |
336 | |
337 | Start with a dummy run of h2xs: |
338 | |
339 | h2xs -Afn Ext::Ension |
340 | |
341 | The only purpose of this step is to create the needed directories, and |
342 | let you know the names of these directories. From the output you can |
343 | see that the directory for the extension is F<Ext/Ension>. |
344 | |
345 | =item Copy C files |
346 | |
347 | Copy your header files and C files to this directory F<Ext/Ension>. |
348 | |
349 | =item Create the extension |
350 | |
351 | Run h2xs, overwriting older autogenerated files: |
352 | |
353 | h2xs -Oxan Ext::Ension interface_simple.h interface_hairy.h |
354 | |
355 | h2xs looks for header files I<after> changing to the extension |
356 | directory, so it will find your header files OK. |
357 | |
358 | =item Archive and test |
359 | |
360 | As usual, run |
361 | |
362 | cd Ext/Ension |
363 | perl Makefile.PL |
364 | make dist |
365 | make |
366 | make test |
367 | |
368 | =item Hints |
369 | |
370 | It is important to do C<make dist> as early as possible. This way you |
371 | can easily merge(1) your changes to autogenerated files if you decide |
372 | to edit your C<.h> files and rerun h2xs. |
373 | |
374 | Do not forget to edit the documentation in the generated F<.pm> file. |
375 | |
376 | Consider the autogenerated files as skeletons only, you may invent |
377 | better interfaces than what h2xs could guess. |
378 | |
379 | Consider this section as a guideline only, some other options of h2xs |
380 | may better suit your needs. |

400 | =head1 LIMITATIONS of B<-x> |
401 | |
402 | F<h2xs> would not distinguish whether an argument to a C function |
403 | which is of the form, say, C<int *>, is an input, output, or |
404 | input/output parameter. In particular, argument declarations of the |
405 | form |
406 | |
407 | int |
408 | foo(n) |
409 | int *n |
410 | |
411 | should be better rewritten as |
412 | |
413 | int |
414 | foo(n) |
415 | int &n |
416 | |
417 | if C<n> is an input parameter. |
418 | |
419 | Additionally, F<h2xs> has no facilities to intuit that a function |
420 | |
421 | int |
422 | foo(addr,l) |
423 | char *addr |
424 | int l |
425 | |
426 | takes a pair of address and length of data at this address, so it is better |
427 | to rewrite this function as |

1963 | A README file is required for CPAN modules since CPAN extracts the |
1964 | README file from a module distribution so that people browsing the |
1965 | archive can use it get an idea of the modules uses. It is usually a |

1967 | decide whether fixes for the module are worth downloading. |
