Adding OpenType features: Long GSUB Strings

William:

I have now made a font Ligatures 006 with the following OpenType code.

script latn { 
    feature DiscretionaryLigatures;
    feature Ligatures;
}

feature DiscretionaryLigatures dlig {
    lookup dligSub;
}  

lookup dligSub {
    sub c t -> c_t;
    sub s h -> s_h;
    sub s t -> s_t;
    sub colon colon one zero zero one six colon semicolon -> ls10016;
    sub colon colon one zero zero one seven colon semicolon -> ls10017;
}

feature Ligatures liga {
    lookup ligaSub;
}

lookup ligaSub {
    sub f f i -> f_f_i;
    sub f f l -> f_f_l;
    sub f f -> f_f;
    sub f i -> fi;
    sub f j -> f_j;
    sub f l -> fl;
    sub d a -> d_a;
    sub longs t -> longs_t;
    sub colon colon -> lsmbob;
    sub colon semicolon -> lsmbcb;
}

My copy of Ligatures 004 seems to lack a glyph for the ‘sh’ ligature. Have you added some new glyphs since then?

Thank you for your interest.

Yes, I added the sh ligature because I did not have an sp ligature that was in the High-Logic default template code from which I started, so I changed it.

Here is the font.
Ligatures 006.otf (20.3 KB)
I got the sh ligature glyph from my Sonnet to a Renaissance Lady font that is available from its own thread in the Gallery section of this forum.

Most of the glyphs in the Ligatures 006 font all come from either the Sonnet to a Renaissance Lady font or from the Localizable Sentences 034 font. The exception is that I made the da ligature specially. This is because I wanted a non-standard ligature to test the font in PagePlus X5.

There is a list of ligature code points that I devised some years ago.

The basic characters for the series of Localizable Sentences fonts all came from the Sonnet to a Renaissance Lady font some years ago..
