Valore Original: Value The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions.	Effect(s)
icase	Character matching should be performed without regard to case.
nosubs	When performing matches, no sub-expression matches should be stored in the supplied std::regex_match structure.
optimize	Instructs the regular expression engine to make matching faster, with the potential cost of making construction slower. For example, this might mean converting a non-deterministic FSA to a deterministic FSA.
collate	Character ranges of the form "[a-b]" will be locale sensitive.
ECMAScript	Use the ECMAScript (JavaScript) regular expression grammar (ECMA-262 grammar documentation), modified to support collating elements, character classes, and equivalence classes from POSIX, and the character class aliases \d, \D, \s, \S, \w, and \W are made locale-sensitive
basic	Use the basic POSIX regular expression grammar (grammar documentation).
extended	Use the extended POSIX regular expression grammar (grammar documentation).
awk	Use the regular expression grammar used by the awk utility in POSIX (grammar documentation)
grep	Use the regular expression grammar used by the grep utility in POSIX. This is effectively the same as the basic option with the addition of newline '\n' as an alternation separator.
egrep	Use the regular expression grammar used by the grep utility, with the -E option, in POSIX. This is effectively the same as the extended option with the addition of newline '\n' as an alternation separator in addtion to '|'.
