It was generated automatically +from the original man page. If there is any nonsense in it, please consult the +man page, in case the conversion went wrong. +<br> +<br><b> +PCRE SAMPLE PROGRAM +</b><br> +<P> +A simple, complete demonstration program, to get you started with using PCRE, +is supplied in the file <i>pcredemo.c</i> in the PCRE distribution. A listing of +this program is given in the +<a href="pcredemo.html"><b>pcredemo</b></a> +documentation. If you do not have a copy of the PCRE distribution, you can save +this listing to re-create <i>pcredemo.c</i>. +</P> +<P> +The demonstration program, which uses the original PCRE 8-bit library, compiles +the regular expression that is its first argument, and matches it against the +subject string in its second argument. No PCRE options are set, and default +character tables are used. If matching succeeds, the program outputs the +portion of the subject that matched, together with the contents of any captured +substrings. +</P> +<P> +If the -g option is given on the command line, the program then goes on to +check for further matches of the same regular expression in the same subject +string. The logic is a little bit tricky because of the possibility of matching +an empty string. Comments in the code explain what is going on. +</P> +<P> +If PCRE is installed in the standard include and library directories for your +operating system, you should be able to compile the demonstration program using +this command: +<pre> + gcc -o pcredemo pcredemo.c -lpcre +</pre> +If PCRE is installed elsewhere, you may need to add additional options to the +command line. For example, on a Unix-like system that has PCRE installed in +<i>/usr/local</i>, you can compile the demonstration program using a command +like this: +<pre> + gcc -o pcredemo -I/usr/local/include pcredemo.c -L/usr/local/lib -lpcre +</pre> +In a Windows environment, if you want to statically link the program against a +non-dll <b>pcre.a</b> file, you must uncomment the line that defines PCRE_STATIC +before including <b>pcre.h</b>, because otherwise the <b>pcre_malloc()</b> and +<b>pcre_free()</b> exported functions will be declared +<b>__declspec(dllimport)</b>, with unwanted results. +</P> +<P> +Once you have compiled and linked the demonstration program, you can run simple +tests like this: +<pre> + ./pcredemo 'cat|dog' 'the cat sat on the mat' + ./pcredemo -g 'cat|dog' 'the dog sat on the cat' +</pre> +Note that there is a much more comprehensive test program, called +<a href="pcretest.html"><b>pcretest</b>,</a> +which supports many more facilities for testing regular expressions and both +PCRE libraries. The +<a href="pcredemo.html"><b>pcredemo</b></a> +program is provided as a simple coding example. +</P> +<P> +If you try to run +<a href="pcredemo.html"><b>pcredemo</b></a> +when PCRE is not installed in the standard library directory, you may get an +error like this on some operating systems (e.g. Solaris): +<pre> + ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such file or directory +</pre> +This is caused by the way shared library support works on those systems. You +need to add +<pre> + -R/usr/local/lib +</pre> +(for example) to the compile command to get round this problem. +</P> +<br><b> +AUTHOR +</b><br> +<P> +Philip Hazel +<br> +University Computing Service +<br> +Cambridge CB2 3QH, England. +<br> +</P> +<br><b> +REVISION +</b><br> +<P> +Last updated: 10 January 2012 +<br> +Copyright © 1997-2012 University of Cambridge. +<br> +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> |
