PCRE SAMPLE PROGRAM +

+
PCRE SAMPLE PROGRAM
+

+A simple, complete demonstration program, to get you started with using PCRE, +is supplied in the file pcredemo.c in the PCRE distribution. +

+The program 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. +

+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. +

+On a Unix system that has PCRE installed in /usr/local, you can compile +the demonstration program using a command like this: +

+  gcc -o pcredemo pcredemo.c -I/usr/local/include \
+      -L/usr/local/lib -lpcre
+

+Then you can run simple tests like this: +

+  ./pcredemo 'cat|dog' 'the cat sat on the mat'
+  ./pcredemo -g 'cat|dog' 'the dog sat on the cat'
+

+Note that there is a much more comprehensive test program, called +pcretest, which supports many more facilities for testing regular +expressions and the PCRE library. The pcredemo program is provided as a +simple coding example. +

+On some operating systems (e.g. Solaris) you may get an error like this when +you try to run pcredemo: +

+  ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such file or directory
+

+This is caused by the way shared library support works on those systems. You +need to add +

+  -R/usr/local/lib
+

+to the compile command to get round this problem. +
