I have been using
\definetextbackground[underline] [location=text,alternative=1,background=,frame=off]
for underlining in my documents and
\startuseMPgraphic{mpos:par:columnset}
\iftracepositions show_multi_pars \else draw_multi_pars \fi ;
path p ; p := boundingbox currentpicture ;
currentpicture := currentpicture shifted (0,-StrutDepth/2) ;
setbounds currentpicture to p ;
\stopuseMPgraphic
to control the depth of the underlining.
Unfortunately, this underlining is still sometimes too far beneath the word underlined. I had thought the problem is the -StrutDepth/2. But even if I change it to an absolute value, the underlines to not appear at the same distance even when the word.
Try this test file:
\definetextbackground[underline] [location=text,alternative=1,background=,frame=off]
\startuseMPgraphic{mpos:par:columnset}
\iftracepositions show_multi_pars \else draw_multi_pars \fi ;
path p ; p := boundingbox currentpicture ;
currentpicture := currentpicture shifted (0,-.50) ;
setbounds currentpicture to p ;
\stopuseMPgraphic
\starttext
Donec \startunderline{gravida}\stopunderline{} posuere arcu.
Donec \startunderline{gravida}\stopunderline{} posuere arcu.
Donec \startunderline{gravida}\stopunderline{} posuere arcu.
Donec \startunderline{gravida}\stopunderline{} posuere arcu.
Donec \startunderline{gravida}\stopunderline{} posuere arcu.
Donec \startunderline{gravida}\stopunderline{} posuere arcu.
Donec \startunderline{gravida}\stopunderline{} posuere arcu.
Donec \startunderline{gravida}\stopunderline{} posuere arcu.
Donec \startunderline{gravida}\stopunderline{} posuere arcu.
Donec \startunderline{gravida}\stopunderline{} posuere arcu.
\stoptext
What I need is underlining that occurs at a fixed/constant distance below the words underlined (allowing for descenders, of course, when they are present).
Any suggestions?
