hellbox-afdko

A hellbox job that wraps executables from AFDKO.

Usage

Import the chutes you need from hellbox.jobs.afdko:

from hellbox.jobs.afdko import MakeOTF, Otf2Ttf, TtfComponentizer

Build OTFs from UFO sources

from hellbox import Hellbox
from hellbox.jobs.afdko import MakeOTF

with Hellbox("build") as task:
    task.read("sources/*.ufo") >> MakeOTF() >> task.write("fonts/")

MakeOTF accepts the following options, all False by default:

Option	AFDKO flag	Description
release	-r	Enable release mode
filter_glyphs	-gs	Filter glyphs to those in the GSUB/GPOS tables
omit_mac_names	-omitMacNames	Omit Macintosh name table entries

Convert OTFs to TTFs

from hellbox import Hellbox
from hellbox.jobs.afdko import MakeOTF, Otf2Ttf

with Hellbox("build") as task:
    task.read("sources/*.ufo") >> MakeOTF() >> Otf2Ttf() >> task.write("fonts/")

Componentize TTFs

TtfComponentizer requires the source UFO to be adjacent to the TTF. hellbox-afdko handles this automatically by symlinking the UFO into the temporary working directory.

from hellbox import Hellbox
from hellbox.jobs.afdko import MakeOTF, Otf2Ttf, TtfComponentizer

with Hellbox("build") as task:
    task.read("sources/*.ufo") \
        >> MakeOTF() \
        >> Otf2Ttf() \
        >> TtfComponentizer() \
        >> task.write("fonts/")
