An extremely simple range lib, for expanding "1..3,5..7"-like strings into [1, 2, 3, 5, 6, 7]
npm install --save jsrangevar range = require('jsrange');
// Every even number from 2 to 100:
range("2 .. 100 x 2");
// -20 to 30, stepping by 3 each time:
range("-20 .. 30 x 3");
// 2, 10, and 11:
range("2, 10, 11");
// 20 down to 12, then 12 back to 20 by 3s:
range("20 .. 12, 12 .. 20 x 3");- You have any number of
,-deliminated sections. Each section will be represented in the result, in order. - Each section should be one of these types:
- A single value.
(eg:"5"or"-20".) - A start and an end value separated by
...
(eg:"1..42"or"7 .. -13") - A start and an end value separated by
.., with a positive step value after ax.
(eg:"1 .. 10 x 3"or"22 .. -13 x 5")
- A single value.
