Wow, Hans, that looks awesome. Thanks a lot.
This is a nice example:
\setuplayout[tight]
\usebodyfont[modern]
\usebodyfont[pagella]
\usebodyfont[ebgaramond]
\usebodyfont[dejavu]
% \enabletrackers[hyphenation.applied]
\enabletrackers[hyphenation.applied.visualize]
% \enabletrackers[hyphenation.applied.console]
\startbuffer
\samplefile{tufte}
\blank
{\hsize 4em \dorecurse{4}{x\discretionary{aa}{bb}{cc}x #1 }}
\blank
\stopbuffer
\starttext
\switchtobodyfont[modern] \getbuffer
\switchtobodyfont[pagella] \getbuffer
\switchtobodyfont[ebgaramond] \getbuffer
\switchtobodyfont[dejavu] \getbuffer
\stoptext
When tex had constructed lines, there are so called discretionary nodes
left; the pre part gets appended at the end of a line, the postpart
injected at the start of the next one. Officially the discretionaries
stay although in mkiv/lmtx we wipe them from the lines.
In the example above you see 'red' glyphs that are the used pre part,
'blue' ones that are the (seldom used) post parts and the 'green' ones
are replacement texts (used when there is no cross linebreak treatment
needed).
Maybe this helps you wikifying it ...
