/* Public options. Some are compile-time only, some are run-time only, and some
are both. Most of the compile-time options are saved with the compiled regex so
that they can be inspected during studying (and therefore JIT compiling). Note
that pcre_study() has its own set of options. Originally, all the options
defined here used distinct bits. However, almost all the bits in a 32-bit word
are now used, so in order to conserve them, option bits that were previously
only recognized at matching time (i.e. by pcre_exec() or pcre_dfa_exec()) may
also be used for compile-time options that affect only compiling and are not
relevant for studying or JIT compiling.
Some options for pcre_compile() change its behaviour but do not affect the
behaviour of the execution functions. Other options are passed through to the
execution functions and affect their behaviour, with or without affecting the
behaviour of pcre_compile().
Options that can be passed to pcre_compile() are tagged Cx below, with these
variants:
C1 Affects compile only
C2 Does not affect compile; affects exec, dfa_exec
C3 Affects compile, exec, dfa_exec
C4 Affects compile, exec, dfa_exec, study
C5 Affects compile, exec, study
Options that can be set for pcre_exec() and/or pcre_dfa_exec() are flagged with
E and D, respectively. They take precedence over C3, C4, and C5 settings passed
from pcre_compile(). Those that are compatible with JIT execution are flagged
with J. */

called dftables (which is distributed with PCRE) can be used to build
alternative versions of this file. This is necessary if you are running in an
EBCDIC environment, or if you want to default to a different encoding, for

happens automatically.

/* The hackery in setting "v" below is to cope with the case when
PCRE2_PRERELEASE is set to an empty string (which it is for real releases).
If the second alternative is used in this case, it does not leave a space
before the date. On the other hand, if all four macros are put into a single
XSTRING when PCRE2_PRERELEASE is not empty, an unwanted space is inserted.
There are problems using an "obvious" approach like this:
XSTRING(PCRE2_MAJOR) "." XSTRING(PCRE_MINOR)
XSTRING(PCRE2_PRERELEASE) " " XSTRING(PCRE_DATE)
because, when PCRE2_PRERELEASE is empty, this leads to an attempted expansion
of STRING(). The C standard states: "If (before argument substitution) any
argument consists of no preprocessing tokens, the behavior is undefined." It
turns out the gcc treats this case as a single empty string - which is what
we really want - but Visual C grumbles about the lack of an argument for the
macro. Unfortunately, both are within their rights. As there seems to be no
way to test for a macro's value being empty at compile time, we have to
resort to a runtime test. */

/* PCRE2 is written in Standard C, but there are a few non-standard things it
can cope with, allowing it to run on SunOS4 and other "close to standard"
systems.
In environments that support the GNU autotools, config.h.in is converted into
config.h by the "configure" script. In environments that use CMake,
config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
hand" without using "configure" or CMake, you should copy the distributed
config.h.generic to config.h, and edit the macro definitions to be the way you
need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
so that config.h is included at the start of every source.
Alternatively, you can avoid editing by using -D on the compiler command line

but if you do, default values will be taken from config.h for non-boolean
macros that are not defined on the command line.
Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
such macros are listed as a commented #undef in config.h.generic. Macros such
as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
sure both macros are undefined; an emulation function will then be used. */

for example, to link from the start of a subpattern to its alternatives and its
end. The use of 16 bits per offset limits the size of an 8-bit compiled regex
to around 64K, which is big enough for almost everybody. However, I received a
request for an even bigger limit. For this reason, and also to make the code
easier to maintain, the storing and loading of offsets from the compiled code

code points. The left property selects a word from the table, and the right
property selects a bit from that word like this:
PRIV(ucp_gbtable)[left-property] & (1u << right-property)
The value is non-zero if a grapheme break is NOT permitted between the relevant
two code points. The breaking rules are as follows:
1. Break at the start and end of text (pretty obviously).
2. Do not break between a CR and LF; otherwise, break before and after
controls.
3. Do not break Hangul syllable sequences, the rules for which are:
L may be followed by L, V, LV or LVT
LV or V may be followed by V or T
LVT or T may be followed by T
4. Do not break before extending characters or zero-width-joiner (ZWJ).
The following rules are only for extended grapheme clusters (but that's what we
are implementing).
5. Do not break before SpacingMarks.
6. Do not break after Prepend characters.
7. Do not break within emoji modifier sequences or emoji zwj sequences. That
is, do not break between characters with the Extended_Pictographic property.
Extend and ZWJ characters are allowed between the characters; this cannot be
represented in this table, the code has to deal with it.
8. Do not break within emoji flag sequences. That is, do not break between
regional indicator (RI) symbols if there are an odd number of RI characters
before the break point. This table encodes "join RI characters"; the code
has to deal with checking for previous adjoining RIs.
9. Otherwise, break everywhere.

/* This function is called (optionally) at the start of compile or match, to
check that a supposed UTF-8 string is actually valid. The early check means
check that a supposed UTF string is actually valid. The early check means
that subsequent code can assume it is dealing with a valid string. The check
can be turned off for maximum performance, but the consequences of supplying an
invalid string are then undefined.
Originally, this function checked according to RFC 2279, allowing for values in
the range 0 to 0x7fffffff, up to 6 bytes long, but ensuring that they were in
the canonical format. Once somebody had pointed out RFC 3629 to me (it
obsoletes 2279), additional restrictions were applied. The values are now
limited to be between 0 and 0x0010ffff, no more than 4 bytes long, and the
subrange 0xd000 to 0xdfff is excluded. However, the format of 5-byte and 6-byte
characters is still checked.

/* PCRE is written in Standard C, but there are a few non-standard things it
can cope with, allowing it to run on SunOS4 and other "close to standard"
systems.
In environments that support the GNU autotools, config.h.in is converted into
config.h by the "configure" script. In environments that use CMake,
config-cmake.in is converted into config.h. If you are going to build PCRE "by
hand" without using "configure" or CMake, you should copy the distributed
config.h.generic to config.h, and edit the macro definitions to be the way you
need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
so that config.h is included at the start of every source.
Alternatively, you can avoid editing by using -D on the compiler command line
to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
but if you do, default values will be taken from config.h for non-boolean
macros that are not defined on the command line.
Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE8 should either be defined
(conventionally to 1) for TRUE, and not defined at all for FALSE. All such
macros are listed as a commented #undef in config.h.generic. Macros such as
MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
PCRE uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
sure both macros are undefined; an emulation function will then be used. */
/* By default, the \R escape sequence matches any Unicode line ending
character or sequence of characters. If BSR_ANYCRLF is defined (to any
value), this is changed so that backslash-R matches only CR, LF, or CRLF.
The build-time default can be overridden by the user of PCRE at runtime. */
/* #undef BSR_ANYCRLF */
/* If you are compiling for a system that uses EBCDIC instead of ASCII
character codes, define this macro to any value. You must also edit the
NEWLINE macro below to set a suitable EBCDIC newline, commonly 21 (0x15).
On systems that can use "configure" or CMake to set EBCDIC, NEWLINE is
automatically adjusted. When EBCDIC is set, PCRE assumes that all input
strings are in EBCDIC. If you do not define this macro, PCRE will assume
input strings are ASCII or UTF-8/16/32 Unicode. It is not possible to build
a version of PCRE that supports both EBCDIC and UTF-8/16/32. */
/* #undef EBCDIC */
/* In an EBCDIC environment, define this macro to any value to arrange for the
NL character to be 0x25 instead of the default 0x15. NL plays the role that
LF does in an ASCII/Unicode environment. The value must also be set in the
NEWLINE macro below. On systems that can use "configure" or CMake to set

/* This module contains global variables that are exported by the PCRE library.
PCRE is thread-clean and doesn't use any global variables in the normal sense.
However, it calls memory allocation and freeing functions via the four
indirections below, and it can optionally do callouts, using the fifth
indirection. These values can be changed by the caller, but are shared between
all threads.
For MS Visual Studio and Symbian OS, there are problems in initializing these
variables to non-local functions. In these cases, therefore, an indirection via
a local function is used.
Also, when compiling for Virtual Pascal, things are done differently, and
global variables are not used. */

/* This table encodes the rules for finding the end of an extended grapheme
cluster. Every code point has a grapheme break property which is one of the
ucp_gbXX values defined in ucp.h. The 2-dimensional table is indexed by the
properties of two adjacent code points. The left property selects a word from
the table, and the right property selects a bit from that word like this:
ucp_gbtable[left-property] & (1 << right-property)
The value is non-zero if a grapheme break is NOT permitted between the relevant
two code points. The breaking rules are as follows:
1. Break at the start and end of text (pretty obviously).
2. Do not break between a CR and LF; otherwise, break before and after
controls.
3. Do not break Hangul syllable sequences, the rules for which are:
L may be followed by L, V, LV or LVT
LV or V may be followed by V or T
LVT or T may be followed by T
4. Do not break before extending characters.
The next two rules are only for extended grapheme clusters (but that's what we
are implementing).
5. Do not break before SpacingMarks.
6. Do not break after Prepend characters.
7. Otherwise, break everywhere.

/* The pcre_utt[] table below translates Unicode property names into type and
code values. It is searched by binary chop, so must be in collating sequence of
name. Originally, the table contained pointers to the name strings in the first
field of each entry. However, that leads to a large number of relocations when
a shared library is dynamically loaded. A significant reduction is made by
putting all the names into a single, large string and then using offsets in the
table itself. Maintenance is more error-prone, but frequent changes to this
data are unlikely.
July 2008: There is now a script called maint/GenerateUtt.py that can be used
to generate this data automatically instead of maintaining it by hand.
The script was updated in March 2009 to generate a new EBCDIC-compliant
version. Like all other character and string literals that are compared against
the regular expression pattern, we must use STR_ macros instead of literal
strings to make sure that UTF-8 support works on EBCDIC platforms. */

"." XSTRING(PCRE_MINOR)
XSTRING(PCRE_PRERELEASE)
" " XSTRING(PCRE_DATE);
However, when PCRE_PRERELEASE is empty, this leads to an attempted expansion of
STRING(). The C standard states: "If (before argument substitution) any
argument consists of no preprocessing tokens, the behavior is undefined." It
turns out the gcc treats this case as a single empty string - which is what we
really want - but Visual C grumbles about the lack of an argument for the
macro. Unfortunately, both are within their rights. To cope with both ways of
handling this, I had resort to some messy hackery that does a test at run time.
I could find no way of detecting that a macro is defined as an empty string at
pre-processor time. This hack uses a standard trick for avoiding calling
the STRING macro with an empty argument when doing the test. */
