Possibly the test suite you mean is not the same as the one that's 
described on this page: http://wiki.contextgarden.net/Test_suite ??? 
That's where I "searched".

Hans, Wolfgang, are you serious? That's just lots of uncommented code 
snippets, many of them don't do nothing or crash in compilation! I 
believe  I mentioned before that I am very new to ConTeXt.


Isn't there any documentation of any of this? Like: "How to make my own 
otf feature at home" -- the script "extensions-001.tex" seems to try 
something like that, but it shows no effect on my machine. Or a bit of 
text that explains the properties and functionalities of 
\definefontfallback in whole sentences? Pointers like that would be very 
welcome.

I'd do that, if I knew what that is and where I can find it.

There should be a file with this name in your ConTeXt folder.

But there isn't. After seraching the whole file system, these are all 
the files with remotely similar names:


--
/usr/share/texmf/tex/context/base$ ls s-l*.mkiv
s-languages-counters.mkiv
s-languages-frequencies.mkiv
s-languages-hyphenation.mkiv
s-languages-sorting.mkiv
s-languages-system.mkiv
s-languages-words.mkiv
-

I have the debian/ubuntu texlive distro that comes with ubuntu 15.10. 
ConTeXt says:


-ConTeXt ver: 2015.05.18 12:26 MKIV current fmt: 
2016.3.18 int: english/english

yes, because type 1 has no such feature processing (i suppose i can make 
them into fake opentypes ... shouldn't be to hard ... it depends a bit 
on how long we keep using type 1)

Yes, many of the blank pages or obscure (to me) error messages seem to 
be font-related. I'll have to see to that.


a lot has been published in articles in user group journals or for 
meetings, there is a font manual that you can buy for nominal costs, 
there are some manuals on the website and an extended version of the 
more technical one that hardly anyone needs will end up in the 
distribution some day soon, there are examples on stack exchange, in 
the mail archive an don the wiki ... a lot of this depends on 
voluntary work so you can hardly complain about it .. anyone is free 
to provide more documentation and share experiences


Yes, I know, I'm sorry I let my exasperation run free. When I started 
out with LaTeX /and/ typesetting more than two decades ago, I had one 
basic book on LaTeX. Over the years my knowledge of LaTeX, typography, 
layout design and typesetting grew side by side, if somewhat organically 
and unsystematic. Nowadays there's about a metre and a half of bookshelf 
occupied by books on LaTeX, TeX and Typography.


As I make books myself, I'm obviously not averse to buying them. I guess 
the ConTeXt books on fonts and layout will do me good.


btw, if you want to roll out your own features as in extensions-001 
then you also need to know what the font provides (or lacks) .. open 
type fonts can be pretty complex and there is no consistency in how 
certain features are implemented


Yes, I learned that already. Will these home-made features only work on 
open type fonts?

Is there a way to tell ConTeXt to use one glyph where it would on its

- In the font "Purisa Medium" the hyphen comes out as a line that is two
or three times fatter and even a little longer than the m-dash. That is
clearly wrong, and probably the font designer's fault. Other than that,
the font has its merits as a not-too-sweet or crazy handwriting font.
I'll need to tell ConTeXt to either scale that monster-hyphen down or to
use a different glyph altogether, maybe even from another font.

- As mentioned in an earlier post, in an \sc group I need the lowercase
ß to be replaced with its smallcaps version, which is contained in the
font but not accessible via any of its otf features.
