2 * PCRE testing program *
3 *************************************************/

5 /* This program was hacked up as a tester for PCRE. I really should have
6 written it more tidily in the first place. Will I ever learn? It has grown and
7 been extended and consequently is now rather, er, *very* untidy in places. The
8 addition of 16-bit support has made it even worse. :-(

39 /* This program now supports the testing of all of the 8-bit, 16-bit, and
40 32-bit PCRE libraries in a single program. This is different from the modules
41 such as pcre_compile.c in the library itself, which are compiled separately for
42 each mode. If two modes are enabled, for example, pcre_compile.c is compiled
43 twice. By contrast, pcretest.c is compiled only once. Therefore, it must not
44 make use of any of the macros from pcre_internal.h that depend on
45 COMPILE_PCRE8, COMPILE_PCRE16, or COMPILE_PCRE32. It does, however, make use of
46 SUPPORT_PCRE8, SUPPORT_PCRE16, and SUPPORT_PCRE32 to ensure that it calls only
47 supported library functions. */

85 makes no difference on Unix-like systems.) Later I was told that it is wrong

208 only from one place and is handled differently). I couldn't dream up any way of
209 using a single macro to do this in a generic way, because of the many different
210 argument requirements. We know that at least one of SUPPORT_PCRE8 and
211 SUPPORT_PCRE16 must be set. First define macros for each individual mode; then
212 use these in the definitions of generic macros.
213
214 **** Special note about the PCHARSxxx macros: the address of the string to be
215 printed is always given as two arguments: a base address followed by an offset.
216 The base address is cast to the correct data size for 8 or 16 bit data; the
217 offset is in units of this size. If the string were given as base+offset in one
218 argument, the casting might be incorrectly applied. */
