contextual alternates

contextual alternates

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \definefontfeature[default][default][script=latn, calt=yes]
    \definefontfamily[mainface][serif][Pecita]
    \setupbodyfont[mainface]
    \starttext
    \input zapf
    \stoptext

The Pecita font is licensed under the Open Font License and it can be
downloaded at http://pecita.eu/b/Pecita.otf.

For some strange reason, the contextual alternates feature isn’t working.

What am I missing here?

Many thanks for your help,


Pablo

There are lots of definitions in calt table, but referenced via 'lookup'
mechanism.

lookup calt5 {
#    sub @calt30' @calt30' by [a.I_ ... f_dotlessi._I];
} calt5;

language ENG ; # English
 script DFLT;
lookup calt5;

To me it is quite unusual.

so the script / language combination is default / english (dflt/eng)

Many thanks for your replies, Hans and Jan.

I’m afraid that the following doesn’t work:

\definefontfeature[default][default][script=latn,language=eng, calt=yes]
\definefontfamily[mainface][rm][Pecita]
\setupbodyfont[mainface]
\starttext
\input zapf
\stoptext

Many thanks for your help,


Pablo

Many thanks for your reply, Hans.

I tested both options (script=latn and script=dflt) and neither worked.

"\definefontfeature[default][default][aalt=yes]" works as expected (even
if I add dflt or latn script). But these are all features.

The weird thing to me is that FontForge displays calt right.

Many thanks for your help,
