Script request: show all overlapping glyph combinations

I would love to have a script that would show me all glyph combinations that are overlapping. This would be a great help when checking kerning.

Imagine you are working on a Heavy condensed typeface. Big chance your /icircumflex (or similar) is partially overlapping some glyphs set next to it.

Thinking out loud, maybe even an extra search setting for a minimal/maximum distance would also be nice.

Could someone help me with that ? How much work would that be and what would it cost ?

So ideally this would be something like Nina Stössinger’s Robofont Extension Touché?

Hi Benedikt ! That is indeed how it should work. I didn’t know Nina had made such a nice tool. Unfortunately, I don’t work with Robofont.

Experimental Glyphs port is available.

@Tosche, thanks a lot !

I installed, together with the latest objectGS and GSpen, but it isn’t working. Or it is very slow. I selected three glyphs to test.

Thank you all anyway, I will wait until a more mature version will be out.

I have an internal Schriftlabor tool that does exactly that, look for overlaps. It is reliable but slow. Georg gave me good input for a better algorithm, and I have been wanting to rewrite it for ages. But I can send you an e-mail with it if you like.

Hi @mekkablue. That would be very nice. I could test it and send you any findings as well.

i had a look at the Touché plugin this afternoon. I could improve the speed by a factor of five. I need to clean it up and will publish it soon.


I just uploaded my changes. Please try.

Thanks, I will.

It is really quick ! Thank you very much.

I’ve installed touché, updated everything but can’t find how to run it. No messages in macro neither… Where should it be in the menus?

I believe that Touché ends up under the Edit menu. fyi.

Me too, but nothing shows up…

Can you check the macro panel for errors?

on G2 opening I just see “Traceback (most recent call last):”

Nothing more?

In console I see
24/04/18 17:43:55,804 Glyphs[60840]: Missing Category Filter: CATEGORIES
24/04/18 17:43:56,166 Glyphs[60840]: Missing Category Filter: All

but It doesn’t seem to be related

found this too in macro, but not related neither?
