Fontmake related issues

Hi,
I’m trying to use fontmake to generate my production fonts files from Glyphs files. I’m having a couple of issues:

  • When using _segment.strokebutt in Glyphs, I get this error, knowing that the given glyph is marked for export. else fontmake won’t apply it at all:
ERROR:ufo2ft.filters.removeOverlaps:Failed to remove overlaps for _segment.strokebutt
fontmake: Error: In 'src/my-font.glyphspackage' -> 'master_ufo/MyFont.designspace': Compiling UFO failed: Unhandled open contour
  • I’m having 3 axis; 2 ‘real’ axis and a virtual one. Their values goes as following: 100->600, 10->30, 10->50. with this config, fontmake complains about unique locations:
WARNING:glyphsLib.builder.sources:DesignSpace sources contain duplicate locations; varLib expects each master to define a unique location. Make sure that you used consistent 'brace layer' names in all the glyph layers that share the same location.
  ['{50, 30, 10}', '{50, 30, 10}'] => {'Weight': 50.0, 'Bowl Size': 30.0, 'Optical size': 10.0}
  ['{110, 30, 10}', '{110, 30, 10}'] => {'Weight': 110.0, 'Bowl Size': 30.0, 'Optical size': 10.0}

and

fontmake: Error: In 'src/atheer.glyphspackage' -> 'master_ufo/MyFont.designspace': Generating fonts from Designspace failed: Locations must be unique.
  • Is it possible to remove overlap in the variable version?

I’m using .glyphspackage format.

Any suggestions?

Thanks in advance

I don’t think that glyphsLib supports segment components, does it?. But corners and segments should always be set to not exporting.
But you should post that on the glyphsLib repo.

Moved to glyphsLib repo, thanks Georg

One thing you could do is to post one problem at a time. Makes the discussion much easier.

Updated the cumbersome issue, it’s related to the axis location only now :smiley: Sorry about that :sweat_smile:
