Hello Hans, thank you very much for this quick fix. I'll have to switch to the beta branch to try it out. At least I can now suppress ligatures with a replacement list, which is enough for now. As far as I understood selnoligs works with regular expressions (black magic!). It is very time consuming, but CPU time is cheap. ;-) Thanks a lot and a nice sunny day. juh Am 11.08.15 um 10:19 schrieb Hans Hagen:

Hi,
I want to follow up on my own message below.
I got the hint offlist that it should not be too difficult to convert a LaTeX package into a ConTeXt module.
I don't know but it would probably be a bit alien approach in the context code base
So I guess that there is no built-in functionality of semantical switching between ligatures and normal characters.
The official way to do this is:
\starttext shel\noligature{ff}ul \stoptext
which also preserves hyphenation and kerning as well as other tricky features that a font provides.
The best place to incorporate such a feature is in the hyphenator but I have no time now to do that. So, instead I added a few lines to an existing (probably unknown) mechanism:
\replaceword[more][shelfful] [shel{ff}ul] \replaceword[more][shifffahrt][shi{ff}fahrt]
\starttext shel\noligature{ff}ul
\setreplacements[more]
shelfful \stoptext
The downside of the 10 line extension is that it's not the most efficient implementation but probably still fast enough.
I am not a typographer – maybe I am wrong – but I don't like ligatures in the wrong places. Inserting ligature stoppers by hand is a tedious work.
I don't like ligatures in most places (why only the few famous ones ... a bit imposed tradition limited to old constraints)
The latex package selnoligs was beneficial to me when I made a book with more than 1000 pages, where I would never managed to stop ligatures by hand.
So what is your opinion about such a feature?
You can probably make a list of special words and adding that to a module is no big deal. I have no time to look into what is around and do that myself.
I uploaded a beta.
Hans
