v6.0.0

❗️ Breaking Changes

• Dropped support for CJS modules. This package is now ESM-only.
• Changed the internal directory structure under lib. If you are importing from a specific file, you need to change the path.

Other Changes

• Migrated the test framework from Jest to Node's Test Runner.
• Set the tests to run only on Node 20, 22, and 24. However, this package is expected to function in any JS environment as long as ESM is supported; if it does not, please file an issue.

v4.0.0

❗️ Breaking Changes

• The string parser no longer accepts unbounded and negative ranges by default. To parse strings possibly containing unbound/negative ranges (eg 10-, (-5)-0), you need to manually pass an option to enable them.

  const userInput = '-5, 10-15, 30, 45-';
  const pagesInMyDoc = [[1, 100]];
  const mr = new MultiRange(userInput, { parseUnbounded: true }).intersect(pagesInMyDoc);

  Note that this affects only the string parser. Array/number initializers always accept unbounded/negative ranges, just as before.

  const mr = new MultiRange([[-5, 3], [10, Inifinity]]); // This is always valid

New

• The constructor now takes an optional options parameter, with which you can modify the parsing strategy. See above.
• MultiRange is now exported also as the default export of the module. You can use import MR from 'multi-integer-range' instead of import { MultiRange as MR } from 'multi-integer-range'.
• Iterator shimming: The type of Symbol.iterator is no longer strictly checked using typeof. This means polyfilled symbols (using core-js or such) will enable MultiRange.prototype[Symbol.iterator], and for ... of loops will correctly transpile to ES5 using Babel or TypeScript (>=2.3 with --downlevelIteration).
• Used ES2015 in the documentation.

v3.0.0

Breaking Changes

• Removed the following methods which had been deprecated since v2.0.0.
  • isContinuous() (Gone for good. Use segmentLength() === 1 instead)
  • hasRange() *
  • appendRange() *
  • subtractRnage() *

It's still possible to access some methods (marked with *) unless you are using TypeScript (these methods were only turned to private methods). They will be there for the time being, although undocumented.

• (TypeScript) *.d.ts file included in the package is now ready for --strictNullChecks. This means TypeScript users need to update their compiler to v2.0 or later to use the definition file. (You do not necessarily have to enable --strictNullChecks flag. See this issue for details.)

New

• Added four convenient methods: min(), max(), shift(), and pop()
