Hi all,

is it possible to subtract a featureset that has been applied to a fontfamily? MWE:

\definefontfeature   [f:frac]   [frac=yes,onum=no,pnum=no]

\definefontfeature   [f:onum]   [onum=yes,pnum=yes]

\definefontfamily [test] [serif] [AntykwaTorunska] [features=f:onum] \definefontfamily [test] [sans]  [Myriad Pro] \definefontfamily [test] [mono]  [DejaVu Sans Mono] \definefontfamily [test] [math]  [Xits Math]

\setupbodyfont[test,12pt]

\starttext

Mozarts erster Satz ist ein {\subtractfeature[f:test]\addfeature[f:frac]4/4}-Takt, Beethoven wählt einen Dreiertakt, Mozarts Romanze ist ein 3/8-Takt, Beethoven wählt einen 2/4, Mozarts Rondo ist eine Gavotte im 2/2-Takt, Beethoven schreibt ein Jagdrondo im 6/8-Takt.

If I comment out the part [features=f:onum], I get the fractions that I'm looking for, but it seems that I can't get the same effect with \subtractfeature and \addfeature. I'm confused...

you forgot the 'default' so you basically force basemode which is does permanent features .. add/subtract works only in node mode \definefontfeature [f:onum] [onum=yes,pnum=yes] \definefontfamily [test] [serif] [AntykwaTorunska] [features={default,f:onum}] \definefontfamily [test] [sans] [Myriad Pro] \definefontfamily [test] [mono] [DejaVu Sans Mono] \definefontfamily [test] [math] [Xits Math] \setupbodyfont[test,12pt] \starttext test 1 2 3 test 1/2 \subtractfeature[f:onum] test 1 2 3 test 1/2 \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
