bracket layers are hiding somewhere

[laerm0]

OpenSans-Italic.glyphs has bracket layers stuck somewhere inside it.

fontmake -g OpenSans-Italic.glyphs -o ufo returns

  File "/Users/stupakm/venvs/type-tools-py3/lib/python3.7/site-packages/glyphsLib/builder/builders.py", line 343, in _apply_bracket_layers
    "Only bracket layers with one numerical (design space) location "
ValueError: Only bracket layers with one numerical (design space) location (meaning the first axis in the designspace file) are currently supported.

@m4rc1e had given me the following short script that would clean this up but no luck here.

font = Glyphs.font

for glyph in font.glyphs:
    new_layers = []
    for layer in glyph.layers:
        if not layer.isSpecialLayer:
            new_layers.append(layer)
    glyph.layers = new_layers

Any thoughts from him or a fellow Glyphs driver out there?

try to make that condition like

if "[" in layer.name or "]" in layer.name:

we should really demote that error to a warning and skip those invalid layers /cc @madig

[anthrotype]

also put some print() statements to see what your layers names look like. I believe they must only contain one integer number within square backets (whitespace is ignored). No commas.

In Glyphs, they can contain more values. And the second one is kind of taken into account. But it is not very useful as you can’t say "first axis > XX && second axis < YY".

[madig]

So both values are min values?

[schriftgestalt]

Both values are min or max depending if it is a bracket or reverse bracket.

[madig]

Are the values in an AND or OR relationship?

[schriftgestalt]

That is an ‘and’.
