alternate end glyphs in MKIV

alternate end glyphs in MKIV

[Jeremy]

Hi all,

I want to get alternate end glyphs. Am I going about it correctly?

I'm using the latext context minimals.

The following compiles fine using the context command, but 'illustrate'
ends with a normal e, not the e.end alternative.

--------- test.tex ------------------------
\usemodule[simplefonts]
\setmainfont[MEgalopolis Extra][features={mode=node,fina=yes}]

\starttext

Text to illustrate

\stoptext
--------- end -----------------------------

Thanks for your help,

Jeremy

\setmainfont[MEgalopolis Extra][script=latin,terminalforms=yes]

You need the latest version because 'terminalforms' (fina) wasn't  
available
in previous ones and the script option is also new (and required here).

This gives me terminal forms, but too many of them. I've marked where
they appear in the following phrase.

    Secret far service
     ^   ^   ^   ^   ^

It looks like they're substituted at the end of every word and
hyphenation point.

Is there any way to have the substitution occur at the end of sentences only?

How do I find this sort of information? I found 'fina' by browsing
through context's otf related files, but grepping all of minimals for
'terminalforms' yields nothing.

Since it appears also in the following minimal example it's either
a bug in context or in the font itself.

\definefontfeature[fina][mode=node,script=latn,fina=yes]
\starttext
{\definedfont[name:megalopolisextra*fina]Secret far service}
\stoptext

you can find in font-ott.lua the following line:

      ['fina'] = 'Terminal Forms',

to use the feature with my module you need the long name as key, it  
doesn't
matter wether you write 'Terminal Forms' (uppercase/lowercase with  
spaces),
'terminal forms' (lowercase with spaces) or 'terminalforms' (lowercase  
without
spaces) but i prefer the third alternative because it follows  
context’s syntax.

Ok.

Which files in minimals should I be looking at to see what's going on?

this is quite doable (but not implemented yet) .. it falls into a 
different category of feature applications (probably doable with one of 
the experimental mechanisms i made for idris)

what font is that?

What files should I look at if I want to try to put something together
myself? I tried modifying luatex-fonts-merged.lua to no effect (in fact,
when I removed it entirely there was no change).
