Configuration settings to limit the number/length of Regexp examples generated

Constant Summary collapse

MAX_REPEATER_VARIANCE_DEFAULT =

The maximum variance for any given repeater, to prevent a huge/infinite number of examples from being listed. For example, if @@max_repeater_variance = 2 then: .* is equivalent to .0,2 .+ is equivalent to .1,3 .2, is equivalent to .2,4 .,3 is equivalent to .0,2 .3,8 is equivalent to .3,5

2
MAX_GROUP_RESULTS_DEFAULT =

Maximum number of characters returned from a char set, to reduce output spam For example, if @@max_group_results = 5 then: d is equivalent to [01234] w is equivalent to [abcde]

5
