* PCRE testing program *

*************************************************/

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

/* This program now supports the testing of all of the 8-bit, 16-bit, and
|
|
32-bit PCRE libraries in a single program. This is different from the modules
|
|
such as pcre_compile.c in the library itself, which are compiled separately for
|
|
each mode. If two modes are enabled, for example, pcre_compile.c is compiled
|
|
twice. By contrast, pcretest.c is compiled only once. Therefore, it must not
|

make use of any of the macros from pcre_internal.h that depend on
|
|
COMPILE_PCRE8, COMPILE_PCRE16, or COMPILE_PCRE32. It does, however, make use of

SUPPORT_PCRE8, SUPPORT_PCRE16, and SUPPORT_PCRE32 to ensure that it calls only

supported library functions. */

use these in the definitions of generic macros.

|
|
**** Special note about the PCHARSxxx macros: the address of the string to be
|
|
printed is always given as two arguments: a base address followed by an offset.
|
|
The base address is cast to the correct data size for 8 or 16 bit data; the

|
offset is in units of this size. If the string were given as base+offset in one
|
|
argument, the casting might be incorrectly applied. */

Complication arises in the case when the newline convention is "any",

"crlf", or "anycrlf". If the previous match was at the end of a line

terminated by CRLF, an advance of one character just passes the \r,

whereas we should prefer the longer newline sequence, as does the code in
|
|
pcre_exec(). Fudge the offset value to achieve this. We check for a
|
|
newline setting in the pattern; if none was set, use PCRE_CONFIG() to
|
|
find the default.

Otherwise, in the case of UTF-8 matching, the advance must be one
