FUNCTIONS

convert_number_sequence_to_range

Usage:

convert_number_sequence_to_range(%args) -> any

Find sequences in number arrays & convert to range (e.g. 100,2,3,4,5,101 -> 100,"2..5",101).

Examples:

  • basic, non-numbers ignored:

    convert_number_sequence_to_range(array => [100, 2 .. 5, 101, "foo"]); # -> [100, "2..5", 101, "foo"]

  • option: separator:

    convert_number_sequence_to_range(array => [100, 2 .. 5, 101], separator => "-"); # -> [100, "2-5", 101]

  • multiple ranges, negative number:

    convert_number_sequence_to_range(array => [100, 2 .. 6, 101, 102, -5 .. -2, 103]);

    Result:

    [100, "2..6", 101, 102, "-5..-2", 103]

  • option: threshold:

    convert_number_sequence_to_range(array => [100, 2 .. 5, 101], threshold => 5); # -> [100, 2 .. 5, 101]

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • array => array[str]

  • separator => str (default: "..")

  • threshold => posint (default: 4)

Return value: (any)
