Having trouble transforming all glyphs

ArrowType

I have a draft font with a character set that is basically A–Z, a–z, and 0–9, plus some punctuation. I’m experimenting with making a narrow version of it via the "Transform All Glyphs" option:

However, it’s getting hung up on the space glyph:

Traceback (most recent call last):
  File "/Applications/RoboFontBeta.app/Contents/Resources/lib/python3.7/vanilla/vanillaBase.py", line 506, in action_
    self.callback(sender)
  File "lib/UI/inspector/transformPane.pyc", line 546, in applyTransformPopUpCallback
  File "lib/UI/inspector/transformPane.pyc", line 572, in _callculateTransformation
  File "lib/tools/transformGlyph.pyc", line 212, in transform

  File "lib/eventTools/editingTool.pyc", line 132, in resetTransform
AttributeError: 'EditingTool' object has no attribute 'transformationLayer'

Is there anything I should do differently to get around this?

Ohhh thank you! This bit is golden. I’ll try to make this a habit.

except Exception as error:
    print(error)

bug already fixed in the newer beta's!

I would avoid catching silently an error. I suggest to change your code in this way:

catch a wider array of exceptions
print the error if caught

f = CurrentFont()

for g in f:
    try:
        oldRightMargin = g.rightMargin
        oldLeftMargin = g.leftMargin
        g.scale((0.25, 1))
        g.leftMargin = oldLeftMargin * 0.25
        g.rightMargin = oldRightMargin * 0.25
    except Exception as error:
        print(error)

Update: I realized that a script could probably do this better, because I also wanted to adjust sidebearings.

This works okay, for a quick prototype:

f = CurrentFont()

for g in f:
    try:
        oldRightMargin = g.rightMargin
        oldLeftMargin = g.leftMargin
        g.scale((0.25,1))
        g.leftMargin = oldLeftMargin * .25
        g.rightMargin = oldRightMargin * .25
    except TypeError:
        pass
