Hey, Jérémie’s question deserves an answer, doesn’t it? There are a lot of people with the same thoughts. Any type of answer will do. But not silence.

thanks for reporting this issue

The snippet works perfect! Thanks a lot! The help window still doesn't appear (I reinstalled MM recently, and Mechanic confirmed it’s the most recent version)

@frederik Yes, I know, but this time I have to use 100 or 0 because of the design of the typeface so what I need is an increase/decrease of 100

I'm curious if anyone else has had randomly had problems with editing their glyphs, their default view setting upon opening, and layer errors? For about two weeks now, as I've been implementing Greek glyphs into a a previously drawn typeface, I've been getting an error when toggling between layers. It always allows me to keep working; however, throws an error callback: Traceback (most recent call last): File "lib/tools/misc.pyc", line 305, in wrapper File "lib/views/doodleLayers/glyphLayer.pyc", line 741, in setLayoutForObject_ File "lib/views/doodleLayers/glyphLayer.pyc", line 744, in setGlyph_ File "lib/views/doodleLayers/glyphLayer.pyc", line 754, in updateGlyph File "lib/views/doodleLayers/glyphLayer.pyc", line 512, in setGlyph_ AttributeError: 'NoneType' object has no attribute 'getRepresentation' Yesterday, however, something more extreme occurred and I can't work on any UFO files anymore! When I open a glyph the editing window is white (screenshot below), and I get this callback: Traceback (most recent call last): File "lib/tools/misc.pyc", line 305, in wrapper File

fs.errors.FilesystemClosed: attempt to use closed filesystem Has anyone else experienced this and/or solved this? Since it happened on the one UFO file, it's now consistent with every UFO on my machine — a major issue for me, to say the least, as I'm supposed to deliver the Greek set before the end of the week. Any help would be greatly appreciated.

Thank you Frederik! You saved me. It's working now :) Have a great weekend, Petra

Hi @naorem, we are polishing a few details and we’ll soon publish version 4.0. It is a matter of days! Thanks for your patience!

moved to a github issue on GlyphConstruction: https://github.com/typemytype/GlyphConstruction/issues/56

I just realized mouse down location in the Skateboard space window is "wrong" and the grey dot indicator at the center of the light dashed crosshairs correctly corresponds to what shows up in the Skateboard Text window. Should tell you how unobservant I can be :) :( 18 ufos in 3 axes in the designspace causes this. 10 ufos in 2 axes does not. My Broadacre font has 10 and Skateboard handles that designspace like a champ. I'm ready to either help isolate the issue or send you these point-compatible ufos and designspace file.

Thank you for the response. Not a critical issue, so happy to wait for RF4. Cheers

every gap inbetween is infinite, how small it might be... and will result in a flickering default glyph. I guess it depends more on how you set up your instances: if you have an instance at 300-700 then I would rather change the rule to substitute at 300-701 701-1000 instead, so you know what you get at the instance.

This does not delete the wrongly named glyph, just in case you store your best drawing there... """ Uncomment what you need: read from file and save or get the current font Best would be to read and fix the .ufo directly """ import defcon # f = defcon.Font("path/to/font.ufo") f = CurrentFont().asDefcon() if "" in f.keys(): f[""].name = "has_a_weird_empty_name_please_change_it" # f.save() good luck

I have the same issue. Virtually unusable atm.

Ah, that makes sense – thank you for the helpful information!

Hi, I have a script that adds mark positioning (plus kerning) to the font when it's being generated. But I have to revert the features to what it was before after the compile. This will make the font dirty. Is it possible to change the features during the compilation without leaving a trace? Here is the script: from vanilla import * from AppKit import NSApp from mojo.events import addObserver, removeObserver from ufo2ft.featureCompiler import FeatureCompiler from collections import OrderedDict """ Postprocessor for font generating font in RoboFont. This one adds mark and kerning to the OTF before the font is generated """ debug = True class addMarkKernOnGenerate(): def __init__(self): windowname = 'Mark Kern UFO2FT' self._featuresBuffer = "" if debug: self.w = Window((500, 50), windowname) self.w.bind("close", self._windowClosed) for window in [w for w in NSApp().orderedWindows() if w.isVisible()]: if window.title() == windowname: window.close() self.w.open() addObserver(self, "_fontDidGenerate", "fontDidGenerate") addObserver(self, "_fontWillGenerate", "fontWillGenerate") def _windowClosed(self, sender): removeObserver(self, "fontDidGenerate") removeObserver(self, "fontWillGenerate") print('removing Observer') def _fontWillGenerate(self, info): f = info["font"] self._featuresBuffer = f.features.text # keep the features in the buffer and revert it back after the generate skipExport = f.lib.get("public.skipExportGlyphs", []) glyphOrder = (gn for gn in f.glyphOrder if gn not in skipExport) featureCompiler = FeatureCompiler(f) featureCompiler.glyphSet = OrderedDict((gn, f[gn]) for gn in glyphOrder) featureCompiler.compile() f.features.text = featureCompiler.features path = info["path"] print(f"{path}: GPOS added using ufo2ft") def _fontDidGenerate(self, info): f = info["font"] f.features.text = self._featuresBuffer addMarkKernOnGenerate() As you can see I keep the font original features in the _featuresBuffer attribute to revert it after the font has been compiled. Many Thanks!

Indeed that is the culprit. Thanks @frederik!

OK, you favor GNFUL (this is already an improvement, as for example dotbelowcmb exists in https://github.com/adobe-type-tools/agl-aglfn/blob/master/glyphlist.txt and thus will be correctly parsed by Adobe apps like Adobe Acrobat). For the Greek, I agree with you: U+00B5, U+2126, U+2206 aren't Greek letters, they're symbols derived from Greek letters and therefore shouldn't receive the same names (and therefore not mu, Omega and Delta). But since we're more or less in agreement, why every time I see this very questionable choice of glyph names (dotbelow, commaaccent, mu, Omega, Delta, and hookabove too), the foundry always responds to me: "we created our fonts with RoboFont"? They're using an old version, with an old version of GNFUL, I have to tell them to update?

@frederik Thank you!!! I had a 2.7 version which I installed for something, I just deleted it and now it works 😄

FYI: this will be tested when RoboFont 4 is going to be tested for release on different macOSs.

Hi For now there is a working beta: get it here and read more https://forum.robofont.com/topic/910/robofont-3-5-beta-i hope this helps!
