Generate font with limited character set

pieterpjotr

Hi,

I'm new to RoboFont so this might be an easy to solve question. I just don't know how to do it...

I'm working on a font with three alternate glyph sets for every uppercase character, managed as stylistic sets in the OpenType font (set 1, 2 and 3). Users who know how to use OpenType fonts can play with the stylistic alternates as they like.

But I would like to generate a second version of the font for users that don't want or don't know how to use the OpenType features (f.e. people that use the font in Word). In that version, all uppercase characters should be replaced with the alternate designs from set 1. All other stylistic alternates (also set 2 and 3) can be deleted in this version.

How can I generate these two fonts (the OpenType with all alternates and the one-option-version) from the same UFO?

All help very much appreciated!

Thanks Frederik! This script does exactly what I was looking for.

a script could help you out:

# get the current font
font = CurrentFont()
# make a copy of it
destFont = font.copy()
# make a list of glyphs to swap
# this could be built automatically if a fixed glyph naming pattern is used
glyphsToSwap = [
   ("A", "A.alt"), 
   ("B", "B.alt"),
]
# loop over all pairs of glyphs to swap
for dest, source in glyphsToSwap:
    # get the glyph objects with those names
    destGlyph = destFont[dest]
    sourceGlyph = destFont[source]
    # insert them in the destination font
    destFont.insertGlyph(sourceGlyph, dest)
    destFont.insertGlyph(destGlyph, source)

# generate the font
destFont.generate(
    format="otf",                            # in .otf format
    path=font.path.replace(".ufo", ".otf"),  # into the same folder
    checkOutlines=True,                      # with remove overlap
    decompose=True,                          # and decompose 
)

Maybe you want to swap them in kerning and kern groups too...

This script allows you to keep the existing feature file.

good luck!
