Hi,
there's this rather new mechanism for preventing ligatures:
\startexceptions[de]
au{f-}{f}{ff}(f\zwnj f)asse
au{f-}{f}{ff}(f\zwnj f)asste
\stopexceptions
Two questions:
1. Can you have multiple \startexceptions[de] environments ? Will they accumulate ? (I'm thinking about preparing a general list of exceptions, but of course you will also want individual exceptions...)
2. What is the exact meaning of these four arguments ? {1}{2}{3} is clear, but what about the parentheses ?
Best,
Denis

the lookup is using the third argument, the replacement is the fourth
auffasste => auf\zwnj fasste
when not hyphenated (without the () the third one is the replacement)
\enabletrackers[hyphenation.applied.visualize]
\startexceptions[de]
au{f-}{f}{ff}as-ste
au{f-}{f}{ff}(f!f)ax-xte
\stopexceptions
\mainlanguage[de]
\dorecurse{100}{#1 auffasste auffaxxte }

Ok, it does...

So, what's the advantage of using
au{f-}{f}{ff}(f\zwnj f)as-ste
over
au{f-}{f}{ff}as-ste
if any?
Besides, is it intentional that this here will suppress the ff ligature?
---------------------------------------------------------------
\enabletrackers[hyphenation.applied.visualize]
\startexceptions[de]
au{f-}{f}{ff}as-sen
\stopexceptions
\mainlanguage[de]
\starttext
auffassen
\stoptext
---------------------------------------------------------------
I don't see why that should happen here.
Denis

Regarding the plan of preparing a list of suppressed ligatures: It seems possible to provide a word list that could just be included with input. OTOH, you'll have to include correct hyphenation for all the words in the list. Is it possible to only define the correct ligature handling in such a list without having to supply hyphenation rules as well?

Well, see attached.
Interestingly, it does with \mainlanguage[de]. But, not for \language[de]
\enabletrackers[hyphenation.applied.visualize]
\startexceptions[de]
au{f-}{f}{ff}as-sen
\stopexceptions
\mainlanguage[de]
\starttext
auffassen
\language[en]
auffassen
\language[de]
auffassen
\stoptext
