@gferreira said in Preserve empty glyphs when applying defcon sort order through script: newGlyphOrder = f.naked().unicodeData.sortGlyphNames(f.templateGlyphOrder, sortDescriptors=[dict(type="cannedDesign", ascending=True, allowPseudoUnicode=True)]) f.templateGlyphOrder = newGlyphOrder Oh, interesting! Sure enough, changing glyphOrder to templateGlyphOrder fixed my script. It now works just as hoped. :) Thanks so much for point out that difference to me!

Thanks, @gferreira! That was a super helpful suggestion, including the link to the defcon docs. I find that for me, the cannedDesign sort type is seemingly identical to the "Smart Sort" option in Robofont, aside from deleting template glyphs. Still, those are easy enough to re-add manually, and something I don't need to do every time (Add Glyphs -> Import from my "Latin 1" character set... -> then select to "add as template glyphs"). So, the script I'll use is very close to your suggestion, but I prefer this sort type: font = CurrentFont() newGlyphOrder = font.naked().unicodeData.sortGlyphNames(font.glyphOrder, sortDescriptors=[dict(type="cannedDesign", ascending=True, allowPseudoUnicode=True)]) font.glyphOrder = newGlyphOrder

You can drag and drop a glyph selection to change the order. The drag starts after 0.4 of a sec, to prevent accidentally reordering of glyphs. You can also set a glyph order with a script: font = CurrentFont() # this is a list of glyph names font.glyphOrder = ["a", "agrave", "b", "c"] if you changed the glyph order (manually or script) the sorting is disabled. There is no glyph index in the UFO data, but each glyph has an glyph.index returning the index related to the glyph order. Please take note that the glyph order in the final font can be different if you don't added .notdef or enabled "Use MacRoman as the start of the glyph order" while compiling. Adding or removing glyphs will always alter the glyph order. It is depending on your settings where new glyphs would be added (at the end or somewhere in a sorted position) Good luck

No really, it remove also the existing templateGlyphs. But: glyphOrder = [] for glyph in f.lib['public.glyphOrder']: glyphOrder.append(glyph) for glyph in myListOfGlyphs: glyphOrder.append(glyph) f.glyphOrder = glyphOrder Thanks Fredrik!

its highly recommended to set at least the four first char as followed: http://partners.adobe.com/public/developer/opentype/index_recs.html
