alphabetical grouping

[visgotti]

Wondering if there's a way to do this? don't want to spend time digging into the source code if not needed, but if this isn't possible I'll implement it myself- anything insightful that'll help me implement this if I need to dig in?

@visgotti Can you describe the meaning of alphabetical grouping? I cannot get it.
Currently, you can group your bins by the tag system.

Check this out:

maxrects-packer/test/maxrects-packer.spec.js

Lines 51 to 71 in 0eeb7d1

	test("adds to bins with tag matching on", () => {
	packer.options.tag = true;
	packer.add(1000, 1000, {number: 1});
	packer.add(10, 10, {number: 2});
	packer.add(1000, 1000, {number: 3, tag: "one"});
	packer.add(1000, 1000, {number: 4, tag: "one"});
	packer.add(10, 10, {number: 5, tag: "one"});
	packer.add(10, 10, {number: 6, tag: "one"});
	packer.add(10, 10, {number: 7, tag: "two"});
	packer.next();
	packer.add(10, 10, {number: 8, tag: "two"});
	expect(packer.bins.length).toBe(5);
	expect(packer.bins[0].rects.length).toBe(2);
	expect(packer.bins[0].tag).toBeUndefined();
	expect(packer.bins[1].rects.length).toBe(3);
	expect(packer.bins[1].tag).toBe("one");
	expect(packer.bins[2].rects.length).toBe(1);
	expect(packer.bins[2].tag).toBe("one");
	expect(packer.bins[packer.bins.length - 1].rects.length).toBe(1);
	expect(packer.bins[packer.bins.length - 1].tag).toBe("two");
	});

so I have sprites.. like walk_frame_1, walk_frame_2 etc. I want these to be binned together, but I also want them one after another in the sprite sheet.

That's not packer's job, you feed the data with width/height/tag and packer return the bins with position data.
Try isolate the filename as the tag, and sort the returning bin data in the program which calling maxrect-packer's API.
