/* 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. */

|
||||
#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
|
