You can play with something based on the following, which I made it 
following suggestions from others. There may well be other ways, but 
this works for me.


   \define\Poemindent{3em}
   \define\Poeminset{14em}
   \definedelimitedtext[Poe]
   \setupwhitespace[medium]
   \showframe

   \startbuffer[Poem]
  This is a long line that breaks,
  the second line,
  the third line.

  The second stanza starts.
   \stopbuffer

   \setupdelimitedtext[Poe][
  rightmargin=\Poeminset,
  leftmargin={\dimexpr\Poemindent+\Poeminset\relax},
  before={\setuplines[
   before=,
    inbetween={\blank[small]},
    after=,
   ]
  \startlines
  \setupindenting[-\Poemindent,yes]
  \startparagraph},
   after=\stopparagraph
 \stoplines,
 ]

   \starttext

   \startparagraph

 Here comes a poem – watch the lines break!

   \stopparagraph

    \startPoe
  \inlinebuffer[Poem]
    \stopPoe

   \startparagraph

 Now, it is gone. Good-bye.

[NTG-context] startlines in margin

[Rik Kabel]

List,

Can somebody suggest an export-friendly mechanism to put fixed lines 
into the margin? Use case: I am reproducing a 17th century text with 
marginal footnotes. I do not need a solution that works with both pdf 
and xml, but there is less mode fiddling if it does.


This example:

   \setupbackend [export=yes]
   \starttext
   \subject{\tex{startlines} in margin}
   \startparagraph
   \margintext{\startlines
   abc def
   ghi
   jkl
   mno pqr
   \stoplines}
   \input knuth
   \stopparagraph

   \subject{\tex{crlf} in margin}
   \startparagraph
   \margintext{abc def\crlf
   ghi\crlf
   jkl\crlf
   mno pqr}
   \input knuth
   \stopparagraph

   \subject{\tex{\textbackslash} in margin}
   \startparagraph
   \margintext{abc def\\
   ghi\\
   jkl\\
   mno pqr}
   \input knuth
   \stopparagraph

   \subject{\tex{startlines} in main flow}
   \startparagraph
   \startlines
   abc def
   ghi
   jkl
   mno pqr
   \stoplines
   \input knuth
   \stopparagraph
   \stoptext

generates the following xml with \startlines and \crlf:

   abc def ghi jkl mno
   pqr

and  no  element at all with \\, while it generates proper lines 
in the main flow:


   abc
   defghijklmno pqr

I also note that \startlines in \margintext does not work in pdf output, 
but both \crlf and \\ do, and \bpar..\epar works in margintext for pdf 
output but breaks strangely in xml (the \epar ends the margintext 
element and the rest is set as body flow paragraphs).

[NTG-context] \startlines in mark IV

[Maurí­cio]

Hi,

I setup this test:

%%%
\starttext
\startlines
\input test.tex
\stoplines
\stoptext
%%%

File 'test.tex' contains just a 'Hello world!'
line. This test goes okay when I use 'texexec'
from default Ubuntu package. When I use 'context'
from minimals, I get a message that ends with:

! Undefined control sequence.
l.3 \input test.tex


If I remove lines '\startlines' and \stoplines'
from the test, I get no errors.

What did I do wrong? Did '\startlines' changed in
Mark IV?

Thanks,
Maurício

[NTG-context] \startlines and whitespace

[frantisek holop]

hi there,

i am puzzled about the following issue.
there's extra whitespace between the centered line
and startlines, while when using \crlf, there is not.
\startlines is an environment i guess (i come from latex)
and some environments sometimes add extra whitespace
in latex, if i recall correctly.

when i use \nowhitespace between midaligned and startlines,
the whitespace is smaller, but still there, depending on
where the actual text is on the page.

how can i get rid of the whitespace entirely?


\starttext

\startnarrower[3cm]
\midaligned{test}
\startlines
There snores -- I mean sleeps -- my wife so frail.
There snores -- I mean sleeps -- my wife so frail.
\stoplines
\stopnarrower

\startnarrower[3cm]
\midaligned{test}
There snores -- I mean sleeps -- my wife so frail.\crlf

Use the before and after mechanism.

\setuplines[before={\startnarrower[3cm]},after=\stopnarrower]

thanks for the tip.
sometimes there still is extra whitespace.  but \nowhitespace
seems to supress them without problems.

i think i should also add, that the document has

\setuptolerance [strict]

so it's not verystrict...

It sounds like perhaps you could have fixed this during the font
import by using afm2pl instead of afm2tfm (afm2tfm has hardwired
rules for the space factor, afm2pl has a switch that allows 
configuration by hand).


But even with afm2tfm, a correct monospace font should have the correct
value assigned. Perhaps the import process worth investigating?


What do I need to fix so that the default \def\normalspace{ } has the

Assuming the font is monospace, you can try this:

  \def\normalspace{\hphantom{0}}


Below is an example file that renders fine with lm/cm, but not my font.


Out of curiosity, which font is it?

This is actually a true type font, so there was never an afm file.
However, I do have a vpl which appears to be correct. Near the head, it
contains:

(FONTDIMEN
   (SLANT R 0.0)
   (SPACE R 0.48)
   (STRETCH R 0.0)
   (SHRINK R 0.0)
   (XHEIGHT R 0.4)
   (QUAD R 1.0)
   (EXTRASPACE R 0.48)
   )

All glphys are (CHARWD R 0.48)

 But even with afm2tfm, a correct monospace font should have the correct
 value assigned. Perhaps the import process worth investigating?

That is very possible. After trying several approaches, I finally
settled on writing my own importer. It 162 lines of very readable (I
like to think) Bash scripting. I have included a compressed version.

  What do I need to fix so that the default \def\normalspace{ } has the
  correct width for the current font?

\def\normalspace{\hphantom{0}}

I will give that a try.

I'm not sure if they are bugs, because they come as a natural
