Error in mekkablue script "Variable font test html"

1

This script only works with the axis name “Weight” for me. All other names produce the following error:‘tag’

Traceback (most recent call last):
  File "Variable Font Test HTML.py", line 1200
    variableFontInfo = otVarInfoForFont(thisFont)
  File "Variable Font Test HTML.py", line 1140, in otVarInfoForFont
    otVarSliders = allOTVarSliders(thisFont)
  File "Variable Font Test HTML.py", line 434, in allOTVarSliders
    tag = axisDict[axis]["tag"]
KeyError: 'tag'

Any hints?

Glyphs 3.1.2 (3151)

I’m seeing a similar thing for a custom axis in Glyphs 3525.:

'MSHQ'
Traceback (most recent call last):
  File "Variable Font Test HTML.py", line 1319
    variableFontInfos.append(otVarInfoForFont(thisFont))
                             ^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "Variable Font Test HTML.py", line 1250, in otVarInfoForFont
    styleMenu = listOfAllStyles(thisFont)
                ^^^^^^^^^^^^^^^^^^^^^^^^^
  File "Variable Font Test HTML.py", line 1221, in listOfAllStyles
    axisValue = coords[axisTag]
                ~~~~~~^^^^^^^^^
KeyError: 'MSHQ'

Had previously worked when the only axis was Weight. If I delete the axis (but not the Virtual Master parameter) I see the same error as above, and when I then remove the VM parameter it works again.

The script works for me. Could you send me your .glyphs file?

Sent, thank you!

I fixed the script.

The problem was that the Axis location parameters in the masters and instances didn’t have a value set for the Virtual masters. And the script depended on this.

Ah nice, thanks. I added the values to the exports, script works again :slight_smile:
