dashed underbar

dashed underbar

[Daniel Schopper]

Dear all,
I'm looking for a solution for dashed underlining. Hacking around I've 
come quite close, with the only problem that when the underlining begins 
at the start of a paragraph there gets an empty (grid) line inserted 
before it. See:

\defineoverlay [backgraphics] [\positionoverlay{backgraphics}]
\setupbackgrounds
   [page]
   [background={backgraphics}]

\setupMPvariables[mpos:par][gridtype=1,gridshift=-0.5ex,gridwidth=0.1ex, 
gridcolor=black,fillcolor=white,linecolor=white]

\newcount\dashulinecounter \dashulinecounter=1

\definestartstop[dashuline][before={\dostartdashuline},after={\dostopdashuline}]
\def\dostartdashuline{%
	\startpositionoverlay{backgraphics}%
	 
\setMPpositiongraphic{b:uline:\the\dashulinecounter}{mpos:par}{self=uline:\the\dashulinecounter}%
	\stoppositionoverlay
	\fpos{uline:\the\dashulinecounter}%
}
\def\dostopdashuline{%
	\tpos{uline:\the\dashulinecounter}%
	\advance\dashulinecounter by 1%
}


\starttext
No Line \startdashuline \dorecurse{20}{This is just a test. 
}\stopdashuline \par
\startdashuline \dorecurse{20}{This is just a test. }\stopdashuline
\stoptext

I'm sure some of you know a simpler and more elegant solution that maybe 
allows even dotted underlining?! Or does anyone have a hint how to get 
rid of the empty line?
Cheers,
Daniel

Well, that was really simple… Any chance to get this working also with 
dots? (Where could I find more on those features? I guess anch-pgr.mkiv 
which seems quite complicated…)
Thanks a lot!

Sorry to bother you again… Unfortunately this doesn't work out right in 
descriptions: after the
first line the underlining starts at the left margin not with the other 
indented lines. Anything one can do about this? Thanks!

\definetextbackground
   [dashed]
   [   location=text,
     framecolor=black,
      alternative=1,
        voffset=-1.2\strutdp,
     background=,
          frame=off,
           dash=1]
\definedescription
    [desc]
    [     width=2em,
      headstyle=normal]
\starttext
\startdesc{Desc:}\startdashed\input ward\stopdashed\stopdesc

Hello,

I tried to add the Wolfgang's solution to wiki, the last example on

http://wiki.contextgarden.net/TextBackground

But the rendered example doesn't show any (dashed) background, although the standalone test file does.

Why?

If the example was rendered otherwise than in reality, it wouldn't have sense to keep it on wiki...

Lukas

The underbar is drawn using metapost. The wiki still uses MkII, and does 
not have write18 enabled. So, you need to add \runMPgraphicsfalse in the 
file (I think that that should be added to cont-usr.tex on the wiki).

I have added that command before \starttext in the wiki extension.

Aditya - can you please test it?

If I remove \runMPgraphicsfalse from the last example on 
http://wiki.contextgarden.net/TextBackground, I do not get the underbar.
