Margin kerning for compounds

Margin kerning for compounds

[Henri Menke]

Dear list,

when writing compound words I want the second part to be eligible for hyphenation to avoid bad breaks.  Therefore, instead of »non-trivial« I write »non|-|trivial«.  However, I noticed that when I make dash compound aware it is no longer kerned into the margin.  MWE is below.  How can I fix this?

Cheers, Henri

Dear list,

I have constructed a better example (and eliminated a grammar error), see below.  I think what »|-|« does is essentially »-\penalty\zerocount\hskip\zeropoint«.  When I insert this as is the margin kerning is correct.  Still, I have no idea how to fix |-|.

Cheers, Henri

Just add

\setbreakpoints[compound]

to the preamble of your documents, and you get both hyphenation and 
margin kerning, no need for |-|.

Oh yeah, right!  Sorry for wasting your time :/  However, as I only want compounds with a hyphen to be breakable (for now) I came up with my own configuration.

\definebreakpoints[hyphen]
\definebreakpoint [hyphen] [-] [nleft=3,nright=3,type=6,range=yes]
\setbreakpoints[hyphen]
