1. You have to enable hanging punctuation which is missing in your example.
2. You have to create your own protrusion vector because the predefined vectors
set hanging for hyphens only for the right margin.
The following example uses code shown in the fonts manual (fonts-mkiv.pdf) to
create a custom protrusion vector:
%%%% begin example
\startluacode
fonts.protrusions.classes.tomas_hala = {
vector = 'tomas_hala',
factor = 1,
}
fonts.protrusions.vectors.tomas_hala = table.merged (
fonts.protrusions.vectors.quality,
{
[0x002D] = { 0.4, 0.7 }, -- hyphen
}
)
\stopluacode
\definebreakpoints [czcompound]
\definebreakpoint [czcompound] [-] [nleft=3,nright=3,type=4]
\startsetups [czech]
\setbreakpoints [czcompound]
\stopsetups
\setuplanguage
[cz]
[setups=czech]
\definefontfeature [default] [default] [protrusion=tomas_hala]
\setupalign [hanging]
\mainlanguage [cz]
\showframe [text] [text]
\starttext
\hsize=0pt
modro-zelený
\stoptext
%%%% end example
