/* 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. */
