func ParseRanges ¶

func ParseRanges(s string, b []int) ([][]int, error)

Parse a series of ranges from text. Multiple ranges can be represented in a comma-delimited list. Individual numbers in the list are treated as a range that includes only that number.

An empty bound in a range is interpreted as "all the numbers from the constraining bound to the other bound". For example, the range "-10", with constraining bounds of [0, 100] means the range "0-10".

Contiguous ranges are merged together.

For example, the input: 0-5,5,6,7,8-10 produces: [[0,10]]

And the input: 0-5,7,9-10 produces: [[0,5],[7,7],[9,10]]
