30 The PCRE APIs
31 -------------
33 PCRE is written in C, and it has its own API. The distribution also includes a
34 set of C++ wrapper functions (see the pcrecpp man page for details), courtesy
35 of Google Inc.
37 In addition, there is a set of C wrapper functions that are based on the POSIX
38 regular expression API (see the pcreposix man page). These end up in the
39 library called libpcreposix. Note that this just provides a POSIX calling
40 interface to PCRE; the regular expressions themselves still follow Perl syntax
41 and semantics. The POSIX API is restricted, and does not give full access to
42 all of PCRE's facilities.
44 The header file for the POSIX-style functions is called pcreposix.h. The
45 official POSIX name is regex.h, but I did not want to risk possible problems
46 with existing files of that name by distributing it that way. To use PCRE with
47 an existing program that uses the POSIX API, pcreposix.h will have to be
48 renamed or pointed at by a link.
50 If you are using the POSIX interface to PCRE and there is already a POSIX regex
51 library installed on your system, as well as worrying about the regex.h header
52 file (as mentioned above), you must also take care when linking programs to
53 ensure that they link with PCRE's libpcreposix library. Otherwise they may pick
54 up the POSIX functions of the same name from the other library.
56 One way of avoiding this confusion is to compile PCRE with the addition of
57 -Dregcomp=PCREregcomp (and similarly for the other POSIX functions) to the
58 compiler flags (CFLAGS if you are using "configure" -- see below). This has the
59 effect of renaming the functions so that the names no longer clash. Of course,
60 you have to do the same thing for your applications, or write them using the
61 new names.
64 Documentation for PCRE
65 ----------------------
67 If you install PCRE in the normal way on a Unix-like system, you will end up
68 with a set of man pages whose names all start with "pcre". The one that is just
69 called "pcre" lists all the others. In addition to these man pages, the PCRE
70 documentation is supplied in two other forms:
72 1. There are files called doc/pcre.txt, doc/pcregrep.txt, and
73 doc/pcretest.txt in the source distribution. The first of these is a
74 concatenation of the text forms of all the section 3 man pages except
75 those that summarize individual functions. The other two are the text
76 forms of the section 1 man pages for the pcregrep and pcretest commands.
77 These text forms are provided for ease of scanning with text editors or
78 similar tools. They are installed in <prefix>/share/doc/pcre, where
79 <prefix> is the installation prefix (defaulting to /usr/local).
81 2. A set of files containing all the documentation in HTML form, hyperlinked
82 in various ways, and rooted in a file called index.html, is distributed in
83 doc/html and installed in <prefix>/share/doc/pcre/html.
86 Contributions by users of PCRE
87 ------------------------------
89 You can find contributions from PCRE users in the directory
91 ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib
93 There is a README file giving brief descriptions of what they are. Some are
94 complete in themselves; others are pointers to URLs containing relevant files.
95 Some of this material is likely to be well out-of-date. Several of the earlier
96 contributions provided support for compiling PCRE on various flavours of
97 Windows (I myself do not use Windows). Nowadays there is more Windows support
98 in the standard distribution, so these contibutions have been archived.
101 Building PCRE on non-Unix systems
102 ---------------------------------
104 For a non-Unix system, please read the comments in the file NON-UNIX-USE,
105 though if your system supports the use of "configure" and "make" you may be
106 able to build PCRE in the same way as for Unix-like systems.
108 PCRE has been compiled on many different operating systems. It should be
109 straightforward to build PCRE on any system that has a Standard C compiler and
110 library, because it uses only Standard C functions.
113 Building PCRE on Unix-like systems
114 ----------------------------------
116 If you are using HP's ANSI C++ compiler (aCC), please see the special note
117 in the section entitled "Using HP's ANSI C++ compiler (aCC)" below.
119 To build PCRE on a Unix-like system, first run the "configure" command from the
120 PCRE distribution directory, with your current directory set to the directory
121 where you want the files to be created. This command is a standard GNU
122 "autoconf" configuration script, for which generic instructions are supplied in
123 the file INSTALL.
125 Most commonly, people build PCRE within its own distribution directory, and in
126 this case, on many systems, just running "./configure" is sufficient. However,
127 the usual methods of changing standard defaults are available. For example:
129 CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
131 specifies that the C compiler should be run with the flags '-O2 -Wall' instead
132 of the default, and that "make install" should install PCRE under /opt/local
133 instead of the default /usr/local.
135 If you want to build in a different directory, just run "configure" with that
136 directory as current. For example, suppose you have unpacked the PCRE source
137 into /source/pcre/pcre-xxx, but you want to build it in /build/pcre/pcre-xxx:
139 cd /build/pcre/pcre-xxx
140 /source/pcre/pcre-xxx/configure
142 PCRE is written in C and is normally compiled as a C library. However, it is
143 possible to build it as a C++ library, though the provided building apparatus
144 does not have any features to support this.
146 There are some optional features that can be included or omitted from the PCRE
147 library. You can read more about them in the pcrebuild man page.
149 . If you want to suppress the building of the C++ wrapper library, you can add
150 --disable-cpp to the "configure" command. Otherwise, when "configure" is run,
151 it will try to find a C++ compiler and C++ header files, and if it succeeds,
152 it will try to build the C++ wrapper.
154 . If you want to make use of the support for UTF-8 character strings in PCRE,
155 you must add --enable-utf8 to the "configure" command. Without it, the code
156 for handling UTF-8 is not included in the library. (Even when included, it
157 still has to be enabled by an option at run time.)
159 . If, in addition to support for UTF-8 character strings, you want to include
160 support for the \P, \p, and \X sequences that recognize Unicode character
161 properties, you must add --enable-unicode-properties to the "configure"
162 command. This adds about 30K to the size of the library (in the form of a
163 property table); only the basic two-letter properties such as Lu are
164 supported.
166 . You can build PCRE to recognize either CR or LF or the sequence CRLF or any
167 of the Unicode newline sequences as indicating the end of a line. Whatever
168 you specify at build time is the default; the caller of PCRE can change the
169 selection at run time. The default newline indicator is a single LF character
170 (the Unix standard). You can specify the default newline indicator by adding
171 --newline-is-cr or --newline-is-lf or --newline-is-crlf or --newline-is-any
172 to the "configure" command, respectively.
174 If you specify --newline-is-cr or --newline-is-crlf, some of the standard
175 tests will fail, because the lines in the test files end with LF. Even if
176 the files are edited to change the line endings, there are likely to be some
177 failures. With --newline-is-any, many tests should succeed, but there may be
178 some failures.
180 . When called via the POSIX interface, PCRE uses malloc() to get additional
181 storage for processing capturing parentheses if there are more than 10 of
182 them in a pattern. You can increase this threshold by setting, for example,
184 --with-posix-malloc-threshold=20
186 on the "configure" command.
188 . PCRE has a counter that can be set to limit the amount of resources it uses.
189 If the limit is exceeded during a match, the match fails. The default is ten
190 million. You can change the default by setting, for example,
192 --with-match-limit=500000
194 on the "configure" command. This is just the default; individual calls to
195 pcre_exec() can supply their own value. There is more discussion on the
196 pcreapi man page.
198 . There is a separate counter that limits the depth of recursive function calls
199 during a matching process. This also has a default of ten million, which is
200 essentially "unlimited". You can change the default by setting, for example,
202 --with-match-limit-recursion=500000
204 Recursive function calls use up the runtime stack; running out of stack can
205 cause programs to crash in strange ways. There is a discussion about stack
206 sizes in the pcrestack man page.
208 . The default maximum compiled pattern size is around 64K. You can increase
209 this by adding --with-link-size=3 to the "configure" command. You can
210 increase it even more by setting --with-link-size=4, but this is unlikely
211 ever to be necessary. Increasing the internal link size will reduce
212 performance.
214 . You can build PCRE so that its internal match() function that is called from
215 pcre_exec() does not call itself recursively. Instead, it uses memory blocks
216 obtained from the heap via the special functions pcre_stack_malloc() and
217 pcre_stack_free() to save data that would otherwise be saved on the stack. To
218 build PCRE like this, use
220 --disable-stack-for-recursion
222 on the "configure" command. PCRE runs more slowly in this mode, but it may be
223 necessary in environments with limited stack sizes. This applies only to the
224 pcre_exec() function; it does not apply to pcre_dfa_exec(), which does not
225 use deeply nested recursion. There is a discussion about stack sizes in the
226 pcrestack man page.
228 . For speed, PCRE uses four tables for manipulating and identifying characters
229 whose code point values are less than 256. By default, it uses a set of
230 tables for ASCII encoding that is part of the distribution. If you specify
232 --enable-rebuild-chartables
234 a program called dftables is compiled and run in the default C locale when
235 you obey "make". It builds a source file called pcre_chartables.c. If you do
236 not specify this option, pcre_chartables.c is created as a copy of
237 pcre_chartables.c.dist. See "Character tables" below for further information.
239 . It is possible to compile PCRE for use on systems that use EBCDIC as their
240 default character code (as opposed to ASCII) by specifying
242 --enable-ebcdic
244 This automatically implies --enable-rebuild-chartables (see above).
246 The "configure" script builds the following files for the basic C library:
248 . Makefile is the makefile that builds the library
249 . config.h contains build-time configuration options for the library
250 . pcre.h is the public PCRE header file
251 . pcre-config is a script that shows the settings of "configure" options
252 . libpcre.pc is data for the pkg-config command
253 . libtool is a script that builds shared and/or static libraries
254 . RunTest is a script for running tests on the basic C library
255 . RunGrepTest is a script for running tests on the pcregrep command
257 Versions of config.h and pcre.h are distributed in the PCRE tarballs under
258 the names config.h.generic and pcre.h.generic. These are provided for the
259 benefit of those who have to built PCRE without the benefit of "configure". If
260 you use "configure", the .generic versions are not used.
262 If a C++ compiler is found, the following files are also built:
264 . libpcrecpp.pc is data for the pkg-config command
265 . pcrecpparg.h is a header file for programs that call PCRE via the C++ wrapper
266 . pcre_stringpiece.h is the header for the C++ "stringpiece" functions
268 The "configure" script also creates config.status, which is an executable
269 script that can be run to recreate the configuration, and config.log, which
270 contains compiler output from tests that "configure" runs.
272 Once "configure" has run, you can run "make". It builds two libraries, called
273 libpcre and libpcreposix, a test program called pcretest, a demonstration
274 program called pcredemo, and the pcregrep command. If a C++ compiler was found
275 on your system, "make" also builds the C++ wrapper library, which is called
276 libpcrecpp, and some test programs called pcrecpp_unittest,
277 pcre_scanner_unittest, and pcre_stringpiece_unittest. Building the C++ wrapper
278 can be disabled by adding --disable-cpp to the "configure" command.
280 The command "make check" runs all the appropriate tests. Details of the PCRE
281 tests are given below in a separate section of this document.
283 You can use "make install" to install PCRE into live directories on your
284 system. The following are installed (file names are all relative to the
285 <prefix> that is set when "configure" is run):
287 Commands (bin):
288 pcretest
289 pcregrep
290 pcre-config
292 Libraries (lib):
293 libpcre
294 libpcreposix
295 libpcrecpp (if C++ support is enabled)
297 Configuration information (lib/pkgconfig):
298 libpcre.pc
299 libpcrecpp.pc (if C++ support is enabled)
301 Header files (include):
302 pcre.h
303 pcreposix.h
304 pcre_scanner.h )
305 pcre_stringpiece.h ) if C++ support is enabled
306 pcrecpp.h )
307 pcrecpparg.h )
309 Man pages (share/man/man{1,3}):
310 pcregrep.1
311 pcretest.1
312 pcre.3
313 pcre*.3 (lots more pages, all starting "pcre")
315 HTML documentation (share/doc/pcre/html):
316 index.html
317 *.html (lots more pages, hyperlinked from index.html)
319 Text file documentation (share/doc/pcre):
322 ChangeLog
324 NEWS
326 pcre.txt (a concatenation of the man(3) pages)
327 pcretest.txt the pcretest man page
328 pcregrep.txt the pcregrep man page
330 Note that the pcredemo program that is built by "configure" is *not* installed
331 anywhere. It is a demonstration for programmers wanting to use PCRE.
333 If you want to remove PCRE from your system, you can run "make uninstall".
334 This removes all the files that "make install" installed. However, it does not
335 remove any directories, because these are often shared with other programs.
338 Retrieving configuration information on Unix-like systems
339 ---------------------------------------------------------
341 Running "make install" installs the command pcre-config, which can be used to
342 recall information about the PCRE configuration and installation. For example:
344 pcre-config --version
346 prints the version number, and
348 pcre-config --libs
350 outputs information about where the library is installed. This command can be
351 included in makefiles for programs that use PCRE, saving the programmer from
352 having to remember too many details.
354 The pkg-config command is another system for saving and retrieving information
355 about installed libraries. Instead of separate commands for each library, a
356 single command is used. For example:
358 pkg-config --cflags pcre
360 The data is held in *.pc files that are installed in a directory called
361 <prefix>/lib/pkgconfig.
364 Shared libraries on Unix-like systems
365 -------------------------------------
367 The default distribution builds PCRE as shared libraries and static libraries,
368 as long as the operating system supports shared libraries. Shared library
369 support relies on the "libtool" script which is built as part of the
370 "configure" process.
372 The libtool script is used to compile and link both shared and static
373 libraries. They are placed in a subdirectory called .libs when they are newly
374 built. The programs pcretest and pcregrep are built to use these uninstalled
375 libraries (by means of wrapper scripts in the case of shared libraries). When
376 you use "make install" to install shared libraries, pcregrep and pcretest are
377 automatically re-built to use the newly installed shared libraries before being
378 installed themselves. However, the versions left in the build directory still
379 use the uninstalled libraries.
381 To build PCRE using static libraries only you must use --disable-shared when
382 configuring it. For example:
384 ./configure --prefix=/usr/gnu --disable-shared
386 Then run "make" in the usual way. Similarly, you can use --disable-static to
387 build only shared libraries.
390 Cross-compiling on Unix-like systems
391 ------------------------------------
393 You can specify CC and CFLAGS in the normal way to the "configure" command, in
394 order to cross-compile PCRE for some other host. However, you should NOT
395 specify --enable-rebuild-chartables, because if you do, the dftables.c source
396 file is compiled and run on the local host, in order to generate the inbuilt
397 character tables (the pcre_chartables.c file). This will probably not work,
398 because dftables.c needs to be compiled with the local compiler, not the cross
399 compiler.
401 When --enable-rebuild-chartables is not specified, pcre_chartables.c is created
402 by making a copy of pcre_chartables.c.dist, which is a default set of tables
403 that assumes ASCII code. Cross-compiling with the default tables should not be
404 a problem.
406 If you need to modify the character tables when cross-compiling, you should
407 move pcre_chartables.c.dist out of the way, then compile dftables.c by hand and
408 run it on the local host to make a new version of pcre_chartables.c.dist.
409 Then when you cross-compile PCRE this new version of the tables will be used.
412 Using HP's ANSI C++ compiler (aCC)
413 ----------------------------------
415 Unless C++ support is disabled by specifying the "--disable-cpp" option of the
416 "configure" script, you must include the "-AA" option in the CXXFLAGS
417 environment variable in order for the C++ components to compile correctly.
419 Also, note that the aCC compiler on PA-RISC platforms may have a defect whereby
420 needed libraries fail to get included when specifying the "-AA" compiler
421 option. If you experience unresolved symbols when linking the C++ programs,
422 use the workaround of specifying the following environment variable prior to
423 running the "configure" script:
425 CXXLDFLAGS="-lstd_v2 -lCsup_v2"
428 Making new tarballs
429 -------------------
431 The command "make dist" creates three PCRE tarballs, in tar.gz, tar.bz2, and
432 zip formats. However, if you have modified any of the man page sources in the
433 doc directory, you should first run the PrepareRelease script. This re-creates
434 the .txt and HTML forms of the documentation from the man pages.
437 Testing PCRE
438 ------------
440 To test the basic PCRE library on a Unix system, run the RunTest script that is
441 created by the configuring process. There is also a script called RunGrepTest
442 that tests the options of the pcregrep command. If the C++ wrapper library is
443 built, three test programs called pcrecpp_unittest, pcre_scanner_unittest, and
444 pcre_stringpiece_unittest are also built.
446 Both the scripts and all the program tests are run if you obey "make check" or
447 "make test". For other systems, see the instructions in NON-UNIX-USE.
449 The RunTest script runs the pcretest test program (which is documented in its
450 own man page) on each of the testinput files in the testdata directory in
451 turn, and compares the output with the contents of the corresponding testoutput
452 files. A file called testtry is used to hold the main output from pcretest
453 (testsavedregex is also used as a working file). To run pcretest on just one of
454 the test files, give its number as an argument to RunTest, for example:
456 RunTest 2
458 The first test file can also be fed directly into the perltest.pl script to
459 check that Perl gives the same results. The only difference you should see is
460 in the first few lines, where the Perl version is given instead of the PCRE
461 version.
463 The second set of tests check pcre_fullinfo(), pcre_info(), pcre_study(),
464 pcre_copy_substring(), pcre_get_substring(), pcre_get_substring_list(), error
465 detection, and run-time flags that are specific to PCRE, as well as the POSIX
466 wrapper API. It also uses the debugging flags to check some of the internals of
467 pcre_compile().
469 If you build PCRE with a locale setting that is not the standard C locale, the
470 character tables may be different (see next paragraph). In some cases, this may
471 cause failures in the second set of tests. For example, in a locale where the
472 isprint() function yields TRUE for characters in the range 128-255, the use of
473 [:isascii:] inside a character class defines a different set of characters, and
474 this shows up in this test as a difference in the compiled code, which is being
475 listed for checking. Where the comparison test output contains [\x00-\x7f] the
476 test will contain [\x00-\xff], and similarly in some other cases. This is not a
477 bug in PCRE.
479 The third set of tests checks pcre_maketables(), the facility for building a
480 set of character tables for a specific locale and using them instead of the
481 default tables. The tests make use of the "fr_FR" (French) locale. Before
482 running the test, the script checks for the presence of this locale by running
483 the "locale" command. If that command fails, or if it doesn't include "fr_FR"
484 in the list of available locales, the third test cannot be run, and a comment
485 is output to say why. If running this test produces instances of the error
487 ** Failed to set locale "fr_FR"
489 in the comparison output, it means that locale is not available on your system,
490 despite being listed by "locale". This does not mean that PCRE is broken.
492 [If you are trying to run this test on Windows, you may be able to get it to
493 work by changing "fr_FR" to "french" everywhere it occurs.]
495 The fourth test checks the UTF-8 support. It is not run automatically unless
496 PCRE is built with UTF-8 support. To do this you must set --enable-utf8 when
497 running "configure". This file can be also fed directly to the perltest script,
498 provided you are running Perl 5.8 or higher. (For Perl 5.6, a small patch,
499 commented in the script, can be be used.)
501 The fifth test checks error handling with UTF-8 encoding, and internal UTF-8
502 features of PCRE that are not relevant to Perl.
504 The sixth test checks the support for Unicode character properties. It it not
505 run automatically unless PCRE is built with Unicode property support. To to
506 this you must set --enable-unicode-properties when running "configure".
508 The seventh, eighth, and ninth tests check the pcre_dfa_exec() alternative
509 matching function, in non-UTF-8 mode, UTF-8 mode, and UTF-8 mode with Unicode
510 property support, respectively. The eighth and ninth tests are not run
511 automatically unless PCRE is build with the relevant support.
514 Character tables
515 ----------------
517 For speed, PCRE uses four tables for manipulating and identifying characters
518 whose code point values are less than 256. The final argument of the
519 pcre_compile() function is a pointer to a block of memory containing the
520 concatenated tables. A call to pcre_maketables() can be used to generate a set
521 of tables in the current locale. If the final argument for pcre_compile() is
522 passed as NULL, a set of default tables that is built into the binary is used.
524 The source file called pcre_chartables.c contains the default set of tables. By
525 default, this is created as a copy of pcre_chartables.c.dist, which contains
526 tables for ASCII coding. However, if --enable-rebuild-chartables is specified
527 for ./configure, a different version of pcre_chartables.c is built by the
528 program dftables (compiled from dftables.c), which uses the ANSI C character
529 handling functions such as isalnum(), isalpha(), isupper(), islower(), etc. to
530 build the table sources. This means that the default C locale which is set for
531 your system will control the contents of these default tables. You can change
532 the default tables by editing pcre_chartables.c and then re-building PCRE. If
533 you do this, you should take care to ensure that the file does not get
534 automatically re-generated. The best way to do this is to move
535 pcre_chartables.c.dist out of the way and replace it with your customized
536 tables.
538 When the dftables program is run as a result of --enable-rebuild-chartables,
539 it uses the default C locale that is set on your system. It does not pay
540 attention to the LC_xxx environment variables. In other words, it uses the
541 system's default locale rather than whatever the compiling user happens to have
542 set. If you really do want to build a source set of character tables in a
543 locale that is specified by the LC_xxx variables, you can run the dftables
544 program by hand with the -L option. For example:
546 ./dftables -L pcre_chartables.c.special
548 The first two 256-byte tables provide lower casing and case flipping functions,
549 respectively. The next table consists of three 32-byte bit maps which identify
550 digits, "word" characters, and white space, respectively. These are used when
551 building 32-byte bit maps that represent character classes for code points less
552 than 256.
554 The final 256-byte table has bits indicating various character types, as
555 follows:
557 1 white space character
558 2 letter
559 4 decimal digit
560 8 hexadecimal digit
561 16 alphanumeric or '_'
562 128 regular expression metacharacter or binary zero
564 You should not alter the set of characters that contain the 128 bit, as that
565 will cause PCRE to malfunction.
