README file for PCRE (Perl-compatible regular expression library) ----------------------------------------------------------------- The latest release of PCRE is always available from ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-xxx.tar.gz There is a mailing list for discussion about the development of PCRE at pcre-dev@exim.org Please read the NEWS file if you are upgrading from a previous release. The contents of this README file are: The PCRE APIs Documentation for PCRE Contributions by users of PCRE Building PCRE on non-Unix systems Building PCRE on Unix-like systems Retrieving configuration information on Unix-like systems Shared libraries on Unix-like systems Cross-compiling on Unix-like systems Using HP's ANSI C++ compiler (aCC) Making new tarballs Testing PCRE Character tables File manifest The PCRE APIs ------------- PCRE is written in C, and it has its own API. The distribution also includes a set of C++ wrapper functions (see the pcrecpp man page for details), courtesy of Google Inc. In addition, there is a set of C wrapper functions that are based on the POSIX regular expression API (see the pcreposix man page). These end up in the library called libpcreposix. Note that this just provides a POSIX calling interface to PCRE; the regular expressions themselves still follow Perl syntax and semantics. The POSIX API is restricted, and does not give full access to all of PCRE's facilities. The header file for the POSIX-style functions is called pcreposix.h. The official POSIX name is regex.h, but I did not want to risk possible problems with existing files of that name by distributing it that way. To use PCRE with an existing program that uses the POSIX API, pcreposix.h will have to be renamed or pointed at by a link. If you are using the POSIX interface to PCRE and there is already a POSIX regex library installed on your system, as well as worrying about the regex.h header file (as mentioned above), you must also take care when linking programs to ensure that they link with PCRE's libpcreposix library. Otherwise they may pick up the POSIX functions of the same name from the other library. One way of avoiding this confusion is to compile PCRE with the addition of -Dregcomp=PCREregcomp (and similarly for the other POSIX functions) to the compiler flags (CFLAGS if you are using "configure" -- see below). This has the effect of renaming the functions so that the names no longer clash. Of course, you have to do the same thing for your applications, or write them using the new names. Documentation for PCRE ---------------------- If you install PCRE in the normal way on a Unix-like system, you will end up with a set of man pages whose names all start with "pcre". The one that is just called "pcre" lists all the others. In addition to these man pages, the PCRE documentation is supplied in two other forms: 1. There are files called doc/pcre.txt, doc/pcregrep.txt, and doc/pcretest.txt in the source distribution. The first of these is a concatenation of the text forms of all the section 3 man pages except those that summarize individual functions. The other two are the text forms of the section 1 man pages for the pcregrep and pcretest commands. These text forms are provided for ease of scanning with text editors or similar tools. They are installed in <prefix>/share/doc/pcre, where <prefix> is the installation prefix (defaulting to /usr/local). 2. A set of files containing all the documentation in HTML form, hyperlinked in various ways, and rooted in a file called index.html, is distributed in doc/html and installed in <prefix>/share/doc/pcre/html. Contributions by users of PCRE ------------------------------ You can find contributions from PCRE users in the directory ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib There is a README file giving brief descriptions of what they are. Some are complete in themselves; others are pointers to URLs containing relevant files. Some of this material is likely to be well out-of-date. Several of the earlier contributions provided support for compiling PCRE on various flavours of Windows (I myself do not use Windows). Nowadays there is more Windows support in the standard distribution, so these contibutions have been archived. Building PCRE on non-Unix systems --------------------------------- For a non-Unix system, please read the comments in the file NON-UNIX-USE, though if your system supports the use of "configure" and "make" you may be able to build PCRE in the same way as for Unix-like systems. PCRE can also be configured in many platform environments using the GUI facility of CMake's CMakeSetup. It creates Makefiles, solution files, etc. PCRE has been compiled on many different operating systems. It should be straightforward to build PCRE on any system that has a Standard C compiler and library, because it uses only Standard C functions. Building PCRE on Unix-like systems ---------------------------------- If you are using HP's ANSI C++ compiler (aCC), please see the special note in the section entitled "Using HP's ANSI C++ compiler (aCC)" below. The following instructions assume the use of the widely used "configure, make, make install" process. There is also some experimental support for "cmake" in the PCRE distribution, but it is incomplete and not documented. However, if you are a "cmake" user, you might want to try it. To build PCRE on a Unix-like system, first run the "configure" command from the PCRE distribution directory, with your current directory set to the directory where you want the files to be created. This command is a standard GNU "autoconf" configuration script, for which generic instructions are supplied in the file INSTALL. Most commonly, people build PCRE within its own distribution directory, and in this case, on many systems, just running "./configure" is sufficient. However, the usual methods of changing standard defaults are available. For example: CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local specifies that the C compiler should be run with the flags '-O2 -Wall' instead of the default, and that "make install" should install PCRE under /opt/local instead of the default /usr/local. If you want to build in a different directory, just run "configure" with that directory as current. For example, suppose you have unpacked the PCRE source into /source/pcre/pcre-xxx, but you want to build it in /build/pcre/pcre-xxx: cd /build/pcre/pcre-xxx /source/pcre/pcre-xxx/configure PCRE is written in C and is normally compiled as a C library. However, it is possible to build it as a C++ library, though the provided building apparatus does not have any features to support this. There are some optional features that can be included or omitted from the PCRE library. You can read more about them in the pcrebuild man page. . If you want to suppress the building of the C++ wrapper library, you can add --disable-cpp to the "configure" command. Otherwise, when "configure" is run, it will try to find a C++ compiler and C++ header files, and if it succeeds, it will try to build the C++ wrapper. . If you want to make use of the support for UTF-8 character strings in PCRE, you must add --enable-utf8 to the "configure" command. Without it, the code for handling UTF-8 is not included in the library. (Even when included, it still has to be enabled by an option at run time.) . If, in addition to support for UTF-8 character strings, you want to include support for the \P, \p, and \X sequences that recognize Unicode character properties, you must add --enable-unicode-properties to the "configure" command. This adds about 30K to the size of the library (in the form of a property table); only the basic two-letter properties such as Lu are supported. . You can build PCRE to recognize either CR or LF or the sequence CRLF or any of the preceding, or any of the Unicode newline sequences as indicating the end of a line. Whatever you specify at build time is the default; the caller of PCRE can change the selection at run time. The default newline indicator is a single LF character (the Unix standard). You can specify the default newline indicator by adding --enable-newline-is-cr or --enable-newline-is-lf or --enable-newline-is-crlf or --enable-newline-is-anycrlf or --enable-newline-is-any to the "configure" command, respectively. If you specify --enable-newline-is-cr or --enable-newline-is-crlf, some of the standard tests will fail, because the lines in the test files end with LF. Even if the files are edited to change the line endings, there are likely to be some failures. With --enable-newline-is-anycrlf or --enable-newline-is-any, many tests should succeed, but there may be some failures. . By default, the sequence \R in a pattern matches any Unicode line ending sequence. This is independent of the option specifying what PCRE considers to be the end of a line (see above). However, the caller of PCRE can restrict \R to match only CR, LF, or CRLF. You can make this the default by adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R"). . When called via the POSIX interface, PCRE uses malloc() to get additional storage for processing capturing parentheses if there are more than 10 of them in a pattern. You can increase this threshold by setting, for example, --with-posix-malloc-threshold=20 on the "configure" command. . PCRE has a counter that can be set to limit the amount of resources it uses. If the limit is exceeded during a match, the match fails. The default is ten million. You can change the default by setting, for example, --with-match-limit=500000 on the "configure" command. This is just the default; individual calls to pcre_exec() can supply their own value. There is more discussion on the pcreapi man page. . There is a separate counter that limits the depth of recursive function calls during a matching process. This also has a default of ten million, which is essentially "unlimited". You can change the default by setting, for example, --with-match-limit-recursion=500000 Recursive function calls use up the runtime stack; running out of stack can cause programs to crash in strange ways. There is a discussion about stack sizes in the pcrestack man page. . The default maximum compiled pattern size is around 64K. You can increase this by adding --with-link-size=3 to the "configure" command. You can increase it even more by setting --with-link-size=4, but this is unlikely ever to be necessary. Increasing the internal link size will reduce performance. . You can build PCRE so that its internal match() function that is called from pcre_exec() does not call itself recursively. Instead, it uses memory blocks obtained from the heap via the special functions pcre_stack_malloc() and pcre_stack_free() to save data that would otherwise be saved on the stack. To build PCRE like this, use --disable-stack-for-recursion on the "configure" command. PCRE runs more slowly in this mode, but it may be necessary in environments with limited stack sizes. This applies only to the pcre_exec() function; it does not apply to pcre_dfa_exec(), which does not use deeply nested recursion. There is a discussion about stack sizes in the pcrestack man page. . For speed, PCRE uses four tables for manipulating and identifying characters whose code point values are less than 256. By default, it uses a set of tables for ASCII encoding that is part of the distribution. If you specify --enable-rebuild-chartables a program called dftables is compiled and run in the default C locale when you obey "make". It builds a source file called pcre_chartables.c. If you do not specify this option, pcre_chartables.c is created as a copy of pcre_chartables.c.dist. See "Character tables" below for further information. . It is possible to compile PCRE for use on systems that use EBCDIC as their default character code (as opposed to ASCII) by specifying --enable-ebcdic This automatically implies --enable-rebuild-chartables (see above). The "configure" script builds the following files for the basic C library: . Makefile is the makefile that builds the library . config.h contains build-time configuration options for the library . pcre.h is the public PCRE header file . pcre-config is a script that shows the settings of "configure" options . libpcre.pc is data for the pkg-config command . libtool is a script that builds shared and/or static libraries . RunTest is a script for running tests on the basic C library . RunGrepTest is a script for running tests on the pcregrep command Versions of config.h and pcre.h are distributed in the PCRE tarballs under the names config.h.generic and pcre.h.generic. These are provided for the benefit of those who have to built PCRE without the benefit of "configure". If you use "configure", the .generic versions are not used. If a C++ compiler is found, the following files are also built: . libpcrecpp.pc is data for the pkg-config command . pcrecpparg.h is a header file for programs that call PCRE via the C++ wrapper . pcre_stringpiece.h is the header for the C++ "stringpiece" functions The "configure" script also creates config.status, which is an executable script that can be run to recreate the configuration, and config.log, which contains compiler output from tests that "configure" runs. Once "configure" has run, you can run "make". It builds two libraries, called libpcre and libpcreposix, a test program called pcretest, a demonstration program called pcredemo, and the pcregrep command. If a C++ compiler was found on your system, "make" also builds the C++ wrapper library, which is called libpcrecpp, and some test programs called pcrecpp_unittest, pcre_scanner_unittest, and pcre_stringpiece_unittest. Building the C++ wrapper can be disabled by adding --disable-cpp to the "configure" command. The command "make check" runs all the appropriate tests. Details of the PCRE tests are given below in a separate section of this document. You can use "make install" to install PCRE into live directories on your system. The following are installed (file names are all relative to the <prefix> that is set when "configure" is run): Commands (bin): pcretest pcregrep pcre-config Libraries (lib): libpcre libpcreposix libpcrecpp (if C++ support is enabled) Configuration information (lib/pkgconfig): libpcre.pc libpcrecpp.pc (if C++ support is enabled) Header files (include): pcre.h pcreposix.h pcre_scanner.h ) pcre_stringpiece.h ) if C++ support is enabled pcrecpp.h ) pcrecpparg.h ) Man pages (share/man/man{1,3}): pcregrep.1 pcretest.1 pcre.3 pcre*.3 (lots more pages, all starting "pcre") HTML documentation (share/doc/pcre/html): index.html *.html (lots more pages, hyperlinked from index.html) Text file documentation (share/doc/pcre): AUTHORS COPYING ChangeLog LICENCE NEWS README pcre.txt (a concatenation of the man(3) pages) pcretest.txt the pcretest man page pcregrep.txt the pcregrep man page Note that the pcredemo program that is built by "configure" is *not* installed anywhere. It is a demonstration for programmers wanting to use PCRE. If you want to remove PCRE from your system, you can run "make uninstall". This removes all the files that "make install" installed. However, it does not remove any directories, because these are often shared with other programs. Retrieving configuration information on Unix-like systems --------------------------------------------------------- Running "make install" installs the command pcre-config, which can be used to recall information about the PCRE configuration and installation. For example: pcre-config --version prints the version number, and pcre-config --libs outputs information about where the library is installed. This command can be included in makefiles for programs that use PCRE, saving the programmer from having to remember too many details. The pkg-config command is another system for saving and retrieving information about installed libraries. Instead of separate commands for each library, a single command is used. For example: pkg-config --cflags pcre The data is held in *.pc files that are installed in a directory called <prefix>/lib/pkgconfig. Shared libraries on Unix-like systems ------------------------------------- The default distribution builds PCRE as shared libraries and static libraries, as long as the operating system supports shared libraries. Shared library support relies on the "libtool" script which is built as part of the "configure" process. The libtool script is used to compile and link both shared and static libraries. They are placed in a subdirectory called .libs when they are newly built. The programs pcretest and pcregrep are built to use these uninstalled libraries (by means of wrapper scripts in the case of shared libraries). When you use "make install" to install shared libraries, pcregrep and pcretest are automatically re-built to use the newly installed shared libraries before being installed themselves. However, the versions left in the build directory still use the uninstalled libraries. To build PCRE using static libraries only you must use --disable-shared when configuring it. For example: ./configure --prefix=/usr/gnu --disable-shared Then run "make" in the usual way. Similarly, you can use --disable-static to build only shared libraries. Cross-compiling on Unix-like systems ------------------------------------ You can specify CC and CFLAGS in the normal way to the "configure" command, in order to cross-compile PCRE for some other host. However, you should NOT specify --enable-rebuild-chartables, because if you do, the dftables.c source file is compiled and run on the local host, in order to generate the inbuilt character tables (the pcre_chartables.c file). This will probably not work, because dftables.c needs to be compiled with the local compiler, not the cross compiler. When --enable-rebuild-chartables is not specified, pcre_chartables.c is created by making a copy of pcre_chartables.c.dist, which is a default set of tables that assumes ASCII code. Cross-compiling with the default tables should not be a problem. If you need to modify the character tables when cross-compiling, you should move pcre_chartables.c.dist out of the way, then compile dftables.c by hand and run it on the local host to make a new version of pcre_chartables.c.dist. Then when you cross-compile PCRE this new version of the tables will be used. Using HP's ANSI C++ compiler (aCC) ---------------------------------- Unless C++ support is disabled by specifying the "--disable-cpp" option of the "configure" script, you must include the "-AA" option in the CXXFLAGS environment variable in order for the C++ components to compile correctly. Also, note that the aCC compiler on PA-RISC platforms may have a defect whereby needed libraries fail to get included when specifying the "-AA" compiler option. If you experience unresolved symbols when linking the C++ programs, use the workaround of specifying the following environment variable prior to running the "configure" script: CXXLDFLAGS="-lstd_v2 -lCsup_v2" Making new tarballs ------------------- The command "make dist" creates three PCRE tarballs, in tar.gz, tar.bz2, and zip formats. The command "make distcheck" does the same, but then does a trial build of the new distribution to ensure that it works. If you have modified any of the man page sources in the doc directory, you should first run the PrepareRelease script before making a distribution. This script creates the .txt and HTML forms of the documentation from the man pages. Testing PCRE ------------ To test the basic PCRE library on a Unix system, run the RunTest script that is created by the configuring process. There is also a script called RunGrepTest that tests the options of the pcregrep command. If the C++ wrapper library is built, three test programs called pcrecpp_unittest, pcre_scanner_unittest, and pcre_stringpiece_unittest are also built. Both the scripts and all the program tests are run if you obey "make check" or "make test". For other systems, see the instructions in NON-UNIX-USE. The RunTest script runs the pcretest test program (which is documented in its own man page) on each of the testinput files in the testdata directory in turn, and compares the output with the contents of the corresponding testoutput files. A file called testtry is used to hold the main output from pcretest (testsavedregex is also used as a working file). To run pcretest on just one of the test files, give its number as an argument to RunTest, for example: RunTest 2 The first test file can also be fed directly into the perltest.pl script to check that Perl gives the same results. The only difference you should see is in the first few lines, where the Perl version is given instead of the PCRE version. The second set of tests check pcre_fullinfo(), pcre_info(), pcre_study(), pcre_copy_substring(), pcre_get_substring(), pcre_get_substring_list(), error detection, and run-time flags that are specific to PCRE, as well as the POSIX wrapper API. It also uses the debugging flags to check some of the internals of pcre_compile(). If you build PCRE with a locale setting that is not the standard C locale, the character tables may be different (see next paragraph). In some cases, this may cause failures in the second set of tests. For example, in a locale where the isprint() function yields TRUE for characters in the range 128-255, the use of [:isascii:] inside a character class defines a different set of characters, and this shows up in this test as a difference in the compiled code, which is being listed for checking. Where the comparison test output contains [\x00-\x7f] the test will contain [\x00-\xff], and similarly in some other cases. This is not a bug in PCRE. The third set of tests checks pcre_maketables(), the facility for building a set of character tables for a specific locale and using them instead of the default tables. The tests make use of the "fr_FR" (French) locale. Before running the test, the script checks for the presence of this locale by running the "locale" command. If that command fails, or if it doesn't include "fr_FR" in the list of available locales, the third test cannot be run, and a comment is output to say why. If running this test produces instances of the error ** Failed to set locale "fr_FR" in the comparison output, it means that locale is not available on your system, despite being listed by "locale". This does not mean that PCRE is broken. [If you are trying to run this test on Windows, you may be able to get it to work by changing "fr_FR" to "french" everywhere it occurs. Alternatively, use RunTest.bat. The version of RunTest.bat included with PCRE 7.4 and above uses Windows versions of test 2. More info on using RunTest.bat is included in the document entitled NON-UNIX-USE.] The fourth test checks the UTF-8 support. It is not run automatically unless PCRE is built with UTF-8 support. To do this you must set --enable-utf8 when running "configure". This file can be also fed directly to the perltest script, provided you are running Perl 5.8 or higher. (For Perl 5.6, a small patch, commented in the script, can be be used.) The fifth test checks error handling with UTF-8 encoding, and internal UTF-8 features of PCRE that are not relevant to Perl. The sixth test checks the support for Unicode character properties. It it not run automatically unless PCRE is built with Unicode property support. To to this you must set --enable-unicode-properties when running "configure". The seventh, eighth, and ninth tests check the pcre_dfa_exec() alternative matching function, in non-UTF-8 mode, UTF-8 mode, and UTF-8 mode with Unicode property support, respectively. The eighth and ninth tests are not run automatically unless PCRE is build with the relevant support. Character tables ---------------- For speed, PCRE uses four tables for manipulating and identifying characters whose code point values are less than 256. The final argument of the pcre_compile() function is a pointer to a block of memory containing the concatenated tables. A call to pcre_maketables() can be used to generate a set of tables in the current locale. If the final argument for pcre_compile() is passed as NULL, a set of default tables that is built into the binary is used. The source file called pcre_chartables.c contains the default set of tables. By default, this is created as a copy of pcre_chartables.c.dist, which contains tables for ASCII coding. However, if --enable-rebuild-chartables is specified for ./configure, a different version of pcre_chartables.c is built by the program dftables (compiled from dftables.c), which uses the ANSI C character handling functions such as isalnum(), isalpha(), isupper(), islower(), etc. to build the table sources. This means that the default C locale which is set for your system will control the contents of these default tables. You can change the default tables by editing pcre_chartables.c and then re-building PCRE. If you do this, you should take care to ensure that the file does not get automatically re-generated. The best way to do this is to move pcre_chartables.c.dist out of the way and replace it with your customized tables. When the dftables program is run as a result of --enable-rebuild-chartables, it uses the default C locale that is set on your system. It does not pay attention to the LC_xxx environment variables. In other words, it uses the system's default locale rather than whatever the compiling user happens to have set. If you really do want to build a source set of character tables in a locale that is specified by the LC_xxx variables, you can run the dftables program by hand with the -L option. For example: ./dftables -L pcre_chartables.c.special The first two 256-byte tables provide lower casing and case flipping functions, respectively. The next table consists of three 32-byte bit maps which identify digits, "word" characters, and white space, respectively. These are used when building 32-byte bit maps that represent character classes for code points less than 256. The final 256-byte table has bits indicating various character types, as follows: 1 white space character 2 letter 4 decimal digit 8 hexadecimal digit 16 alphanumeric or '_' 128 regular expression metacharacter or binary zero You should not alter the set of characters that contain the 128 bit, as that will cause PCRE to malfunction.
