- abortTrialRepetitionsOnInherentFailure :: Bool
If an alternative can't match, irrespective of the subsequent RegExDot.RegEx.Concatenation, then avoid futile trial RegExDot.Repeatable.Repetitions. The converse of checkForUnconsumableData
.
- abortTrialRepetitionsOnZeroConsumption :: Bool
Check for zero data-consumption by the n
-th RegExDot.Repeatable.Repeatable RegExDot.RegEx.CaptureGroup, before attempting n+1
.
- bypassInputDataForLiberalConsumer :: Bool
Whether to bypass reading of the input data, if the mapping to specific RegExDot.RegEx.RepeatablePatterns isn't required, & the RegExDot.RegEx.ExtendedRegEx can consume the required quantity of anything.
- catchIncompatibleAnchors :: Bool
Avoid futile trial solutions, involving repetitions of anchored alternatives, which must consume data.
- checkExistenceOfInelasticTail :: Bool
If the RegExDot.RegEx.ExtendedRegEx ends in an inelastic (zero Star-height) tail, confirm its existence at the end of the RegExDot.RegEx.InputData.
- checkForUnconsumableData :: Bool
Check whether there's no possibility of consuming some of the input data. The converse of abortTrialRepetitionsOnInherentFailure
.
- moderateGreed :: Bool
Greedily consume data, only up to the limit beyond which, future requirements would be compromised.
- permitReorderingOfAlternatives :: Bool
Permit RegExDot.RegEx.Alternatives to be re-ordered, in an attempt to more quickly locate a result.
- preferAlternativesWhichFeedTheGreedy :: Bool
Within the RegExDot.RegEx.MatchedData from which each candidate RegExDot.RegEx.Match amongst sequences of RegExDot.RegEx.Alternatives, is ultimately composed, prefer RegExDot.ConsumptionBounds.ConsumptionBounds of RegExDot.RegEx.InputData, beyond RegExDot.Repeatable.getFewest, by RegExDot.Repeatable.isGreedy RegExDot.RegEx.RepeatablePatterns.
- preferAlternativesWhichMimickUnrolling :: Bool
Compare RegExDot.ConsumptionBounds.ConsumptionBounds on successive RegExDot.Repeatable.Repetitions of RegExDot.RegEx.CaptureGroup, between candidate RegExDot.RegEx.Matches, to mimic the behaviour of the unrolled RegExDot.Repeatable.Repetitions.
- preferFewerRepeatedAlternatives :: Bool
Prefer fewer RegExDot.Repeatable.Repetitions of RegExDot.RegEx.Alternatives, to discourage the capture of null lists of RegExDot.RegEx.InputData.
- requireMatchList :: Bool
If merely interested in a Bool
result, rather than the optimal mapping of input data to RegExDot.RegEx.RepeatablePatterns, avoid unnecessary evaluation of the RegEx.Match.
- unrollRepeatedSingletonAlternative :: Bool
Check whether RegExDot.RegEx.Alternatives consists of just a singleton RegExDot.RegEx.ExtendedRegEx, & has therefore been used merely as a capture-group. Though this doesn't affect the result, it vastly improves efficiency.
- useFirstMatchAmongAlternatives :: Bool
Rather than performing an exhaustive search for the optimal choice amongst RegExDot.RegEx.Alternatives, merely select the first that matches; conform to Perl rather than POSIX.
- validateMinConsumptionOfAlternatives :: Bool
When the number of repetitions of a RegExDot.RegEx.CaptureGroup is precisely specified, check whether the resulting minimum data-requirement is available.
