You could try the attached, which is the 2.20.0 source code for the 
teaching accidental style (+some helper functions) with one change to 
accommodate 2.18 syntax, i.e. the key signature is obtained from the 
localKeySignature context property instead of localAlterations. Thus the 
code does not work with Lilypond 2.20.0. Also note the override is no 
longer necessary.
