Hi again, 

In case someone else is wondering, it looks like \setupalign[stretch,fullhz] prevents breaks after hyphens in the examples I've tried.

Cheers,
Florent

Hi, 

Thanks a lot Hans and everyone who has worked on it for the new upload! From what I can tell from my few projects, math in HTML export seems to have significantly improved. 

I have just noticed what seems to be a small issue with hyphenated words in the HTML export: an extra space is added when the pdf output has a line break after the hyphen. Here is a minimal example showing the issue:

__________________________________________
\setupbackend[export=yes]
\starttext
blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah co-worker
\stoptext
__________________________________________

(The number of ‘blah’s is adjusted to that ConTeXt adds a line break after ‘co-’ in the pdf.)
The relevant part of the .html output is: 

<div>
blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah co- worker</div>

(Notice the space after ‘co-’.) 

Would there be a way to avoid this extra space? As an alternative, is it possible to prevent line breaks after a hyphen? 

(I tried playing with \setupbreakpoint, e.g., \setupbreakpoint[test][-][nleft=100,nright=100], but did not manage to get it working for the hyphens, although it seems to work well for other characters.)

Cheers,
Florent
