Sidebearing arithmetics == opposite

1

Hi! I’ve been reading on the sidebearing arithmetics article and found the double equal sign very useful. But I was wondering if there was an opposite equivalent equation to it?

I am trying to make a monospace master together with my proportional romans, and wanted to keep glyph names/equations in the sidebearings, but make the mono master’s sidebearings only as free numbers/no equation (because it needs the width to be the same instead.)

(or if there’s a better approach to doing this, would be very helpful)

Can you try adding an “isFixedPitch” custom parameter to your monospace masters?

Careful: make a backup of your file beforehand, as this will set the width of all layers of that master to the width of the space glyph.

I don’t think the “isFixedPitch” parameter works on masters. Only on the font and instances. (it might be useful on the masters, but what happens to the parameter if you interpolate between a master that has it and one that hasn’t?)

Ah. Makes sense.

In that case: add a .monospace number value to your monospace masters, this will set the width of all layers to that value.

Then, in the exports, set the isFixedPitch custom parameter for the monospace instances.
