how to save RKerning and RGroups to fea file?

RafaŁ Buchner

Hey,
Is there a simple way to save kerning objects to fea code with the script?
I cannot find any option online. I've been trying to do it with fontTools but I had no success

@RafaŁ-Buchner Here is a method using ufo2fdk.

from ufo2fdk.kernFeatureWriter import KernFeatureWriter
for font in AllFonts():
    path = font.path
    kernPath = path.replace(".ufo"," kern.fea")
    w = KernFeatureWriter(font)
    output = w.write()
    k = open(kernPath, 'w')
    k.write(output)
    k.close()
    print("exporting %s %s kerning feature" % (font.info.familyName, font.info.styleName))

@connor said in how to save RKerning and RGroups to fea file?:

fonts = metricsMachine.AllFonts()
for f in fonts:
kernPath = f.path.replace(".ufo"," kern.fea")
f.kerning.exportFeatureText(kernPath, insertSubtableBreaks=False)
print("exporting %s %s kerning feature" % (f.info.familyName, f.info.styleName))

Thanks @connor, it should work for now. Nonetheless, I would rather use some stuff that would run independently from other extensions. Default RF's libraries only.

If you use the MM scripting API you can do:

fonts = metricsMachine.AllFonts()
for f in fonts:
    kernPath = f.path.replace(".ufo"," kern.fea")
    f.kerning.exportFeatureText(kernPath, insertSubtableBreaks=False)
    print("exporting %s %s kerning feature" % (f.info.familyName, f.info.styleName))
