Bug in API when accessing TT hints?

Scripting
#1

Hi Glyphs dev team,

I am trying to write a script to detect when vertical TT hints are pointing in the wrong direction:

# find TT hints pointing towards the alignment zones instead of away from them
glyphs=[]
hintsFound=False
for g in Font.glyphs:
	for l in g.layers:
		if l.isMasterLayer or l.isSpecialLayer:
			for h in l.hints:
				hintsFound = True
				if h.horizontal and h.type==TTSTEM: # h.horizontal seems to be true for vertical hints(!)
					for z in l.master.alignmentZones:
					    [...]

As you can see, h.horizontal seems to be the wrong way round, i.e. True for vertical hints (and presumably False for horizontal ones). Is this a bug?

Are you using Glyphs 2 or 3?

Works for me as expected. Have you checked the “presumable”.

#3

Thanks, Georg. I’m still using Glyphs 2.
I’m not sure if I understand what you mean by “presumable”

I’ve just checked the return values of the method and it seems to be returning 1 if horizontal and 0 if vertical. The documentation states that the return type is bool.

Given that there is no handbook for Glyphs 3 yet, I am assuming that the Glyphs API documentation also still refers to Glyphs 2.6.6, is that right?
https://docu.glyphsapp.com/#GSHint.horizontal

Also, the documentation states that the return type of GSHint.targetNode is always a GSNode but in many cases the method returns a GSHandle (presumably when it’s an interpolated node).

Am I using the correct documentation?

#4

You said: “and presumably False for horizontal ones”.

I fixed the type in the Glyphs 3 wrapper.

No, the docu.glyphsapp.com is updated. It has nothing to do with the handbook. I’ll fix the documentation with the targetNode type.

#5

Thanks, Georg, that’s good to know. As we’re still on Glyphs 2.x for our production workflow, is there an archive of the API documentation for Glyphs 2? I presume some things will have changed for Glyphs 3.
