/* When compiling a DLL for Windows, the exported symbols have to be declared
|
|
|
|
|
using some MS magic. I found some useful information on this web page:
|
|
|
|
|
http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
|
|
|
|
|
information there, using __declspec(dllexport) without "extern" we have a
|
|
|
|
|
definition; with "extern" we have a declaration. The settings here override the
|
|
|
|
|
setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
|
|
|
|
|
which is all that is needed for applications (they just import the symbols). We
|
|
|
|
|
use:
|
|
|
|
|
|
|
|
|
|
PCRE_EXP_DECL for declarations
|
|
|
|
|
PCRE_EXP_DEFN for definitions of exported functions
|
|
|
|
|
PCRE_EXP_DATA_DEFN for definitions of exported variables
|
|
|
|
|
|
|
|
|
|
The reason for the two DEFN macros is that in non-Windows environments, one
|
|
|
|
|
does not want to have "extern" before variable definitions because it leads to
|
|
|
|
|
compiler warnings. So we distinguish between functions and variables. In
|
|
|
|
|
Windows, the two should always be the same.
|
|
|
|
|
|
|
|
|
|
The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
|
|
|
|
|
which is an application, but needs to import this file in order to "peek" at
|
|
|
|
|
internals, can #include pcre.h first to get an application's-eye view.
|
|
|
|
|
|
|
|
|
|
In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
|
|
|
|
|
special-purpose environments) might want to stick other stuff in front of
|
|
|
|
|
exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
|
|
|
|
|
PCRE_EXP_DATA_DEFN only if they are not already set. */

would need different lookups depending on whether PCRE_UTF8 was set or not.
|
|
|
|
|
This would make it impossible to use characters in switch/case statements,
|
|
|
|
|
which would reduce performance. For a theoretical use (which nobody has asked
|
|
|
|
|
for) in a minority area (EBCDIC platforms), this is not sensible. Any
|
|
|
|
|
application that did need both could compile two versions of the library, using
|
|
|
|
|
macros to give the functions distinct names. */

/* UTF-8 support is not enabled; use the platform-dependent character literals
|
|
|
|
|
so that PCRE works in both ASCII and EBCDIC environments, but only in non-UTF
|
|
|
|
|
mode. Newline characters are problematic in EBCDIC. Though it has CR and LF
|
|
|
|
|
characters, a common practice has been to use its NL (0x15) character as the
|
|
|
|
|
line terminator in C-like processing environments. However, sometimes the LF
|
|
|
|
|
(0x25) character is used instead, according to this Unicode document:
|
|
|
|
|
|
|
|
|
|
http://unicode.org/standard/reports/tr13/tr13-5.html
|
|
|
|
|
|
|
|
|
|
PCRE defaults EBCDIC NL to 0x15, but has a build-time option to select 0x25
|
|
|
|
|
instead. Whichever is *not* chosen is defined as NEL.
|
|
|
|
|
|
|
|
|
|
In both ASCII and EBCDIC environments, CHAR_NL and CHAR_LF are synonyms for the
|
|
|
|
|
same code point. */

non-DOTALL mode, "." behaves like \N.

The special values ESC_DU, ESC_du, etc. are used instead of ESC_D, ESC_d, etc.

Negative numbers are used to encode a backreference (\1, \2, \3, etc.) in

check_escape(). There are two tests in the code for an escape
|
|
|
|
|
greater than ESC_b and less than ESC_Z to detect the types that may be
|
|
|
|
|
repeated. These are the types that consume characters. If any new escapes are
|
|
|
|
|
put in between that don't consume a character, that code will have to change.

offset to the name table so that if a regex is compiled on one host, saved, and

be well.
|
|
|
|
|
|
|
|
|
|
The size of the structure must be a multiple of 8 bytes. For the case of
|
|
|
|
|
compiled-on-4 and run-on-8, we include an extra pointer that is always NULL so
|
|
|
|
|
that there are an even number of pointers which therefore are a multiple of 8
|
|
|
|
|
bytes.
|
|
|
|
|
|
|
|
|
|
It is necessary to fork the struct for the 32 bit library, since it needs to
|
|
|
|
|
use pcre_uint32 for first_char and req_char. We can't put an ifdef inside the
|
|
|
|
|
typedef because pcretest needs access to the struct of the 8-, 16- and 32-bit
|
|
|
|
|
variants.
|
|
|
|
|
|
|
|
|
|
*** WARNING ***
|
|
|
|
|
When new fields are added to these structures, remember to adjust the code in
|
|
|
|
|
pcre_byte_order.c that is concerned with swapping the byte order of the fields
|
|
|
|
|
when a compiled regex is reloaded on a host with different endianness.
|
|
|
|
|
*** WARNING ***
|
|
|
|
|
There is also similar byte-flipping code in pcretest.c, which is used for
|
|
|
|
|
testing the byte-flipping features. It must also be kept in step.
