Two framed texts on the same line

Two framed texts on the same line

[Giuseppe Bilotta]

Hello, I would like to achieve this kind of typographical
effect: two text blocks, one of them aligned to the left
margin, the other with left-aligned text but with the right
margin at the right margin of the page.

I can obtain each of them with for example the following:

\defineframedtext[lepi][align=raggedright,width=fit,offset=0pt,frame=off,location=left]
\defineframedtext[repi][align=raggedright,width=fit,offset=0pt,frame=off,location=right]

Now, I want them to be "at the same height". However, using
things like placesidebyside or even just \startlepi ...
\stoplepi \startrepi ... \stoprepi  doesn't work.

Any suggestions?

depends a bit on the usage; the following shows you a few tricks

\defineframedtext
  [gb]
  [align=raggedright,
   width=.5\textwidth,
   offset=0pt,
   frame=off,
   before=,
   after=]

\startbuffer[left]
\startgb[none]
\input tufte
\stopgb
\stopbuffer

\startbuffer[right]
\startgb[none]
\input zapf
\stopgb
\stopbuffer

\starttext

\input tufte

\definepairedbox[gb][location={right,top}]

\startbaselinecorrection
\placepairedbox[gb]
  {\getbuffer[left]}
  {\getbuffer[right]}
\stopbaselinecorrection

\input zapf

\stoptext

Oh, interesting this pairedbox thing (it's undocumented,
though). I was hoping to be able to do it like this:

\defineframedtext[lepi][align=raggedright,width=fit,offset=0pt,frame=off,location=left]
\defineframedtext[repi][align=raggedright,width=fit,offset=0pt,frame=off,location=right]
\definepairedbox[epi][location={right,top}]

\placepairedbox[epi]
{\startlepi
{\bf Coordinatore}\par
prof. F.~Nicolosi
\stoplepi}
{\startrepi
{\bf Tutor}\par
prof. G.~Russo
\stoprepi}

But it won't work because the second box (repi) gets placed
with its LEFT margin on the right margin of the page,
whereas I needed to be with its right margin at the right
margin of the page. I think the problem is that, from what I
get by reading the source, in paired boxes are not treated
equally.

Basically, the rpbolem seems to be that the width of the
lepi framed text is not the 'natural width' of the text,
despite the width=fit command ... why is this so?

no, you need to bypass the location handling in framed texts

so, replacing left and right by none should do the trick, however, i 
found out that this demands an extra line of code in core-rul.tex (see 
'newer' below)

\def\dodostopframedtext#1#2% % no \baselinecorrection, see faq docs
  {\endgraf
   \removelastskip
   \doifvalue{\??kd#1\c!depthcorrection}\v!on % local and global
     {\forgetall
      \vskip-\struttotal
      \verticalstrut
      \egroup
      \forgetall
      \vskip-\lineheight
      % will be an option, not default
      % \setbaselinecorrections
      % \donegbotbaselinecorrection
      \verticalstrut}
   \stopboxedcontent
   \stopcolor
   \egroup
   \doif{#2}\v!none\insidefloattrue % new
   \doif{\framedtextparameter{#1}\c!location}\v!none\insidefloattrue % 
newer
   \ifinsidefloat
     \box\framebox
   \else
     \doplacement[\??kd#1][\c!depthcorrection=\v!off]{\box\framebox}%
   \fi
   \egroup}

see \doplacement in the previous code, you need to have the then branch; 
placement is for placemen tin the running text (and looks at the text 
width)

Hm, strange, I patched core-rul and redumped the format, but
location=none still doesn't work. However, \startlepi[none]
does, so I'll go by this for the time being, thanks.

For what it's worth, I'm now using the following:


\defineframedtext[lepi][align=raggedright,width=fit,offset=0pt,frame=off,location=none]
\defineframedtext[repi][align=raggedright,width=fit,offset=0pt,frame=off,location=none]
\definepairedbox[lrepi][location={right,top}]

\noindent
\startlepi[none]
\obeylines
{\bf Coordinatore}
prof. F.~Nicolosi
\stoplepi\hfill\startrepi[none]
\obeylines
{\bf Tutor}
prof. G.~Russo
\stoprepi

The [none] spec is required until the location=none
specification is fixed :)

TeX does complain about underfull boxes, but the output is
just what I need.

ok. to get rid of messages, say \dontcomplain
