Verbatim typing with numbers inside float

Verbatim typing with numbers inside float

[Stefan Müller]

Hi list,

I defined a float for typesetting algorithms, so I can reference them at 
other places in the document.

   \definefloat[algorithm][algorithms]

When I now place such a figure with

   \placealgorithm[here][alg:myalgorithm]{Very neat algorithm.}{
   \starttyping
   some source code
   \stoptyping
   }

then the numbering I set up with

   \setuptyping[numbering=line]
   \setuplinenumbering[location=text]

is gone. Is there a way to get around this? I try to not use itemize for 
this (although it seems to work with itemize), because I'd rather use 
the more semantically correct approach. Any help appreciated.

Thanks in advance,
Stefan.

needs a bit of thinking ... (deeply burried numbering)

this sort of works

\startbuffer
some source code
some source code
some source code
\stopbuffer

\setuplinenumbering[style=\ttx,distance=0em,width=1em]

\startsetups algorithm
     \startlinenumbering
     \setuptyping[file][before=,after=]
     \framed[strut=no,align=normal,frame=off]{\typebuffer}
     \stoplinenumbering
\stopsetups

\placealgorithm
   [here][alg:myalgorithm]
   {Very neat algorithm.}
   {\directsetup{algorithm}}

Thank you very much for your effort. Pretty amazing what's doable. 
Unfortunately there are two issues: The distance between numbers and 
source lines is too small for bigger line numbers. I just have to make 
"distance=0em" big enough for this to work, right?

The other thing: The width available for the caption is capped by the 
width of the longest source line. I think I prefer the source lines to 
start at the left margin.

In addition there is something else I didn't think of when I put up that 
mail (sorry for that). If I put (a very long piece) source inside a 
figure I won't have pagebreaks, right? So this makes me think it's 
probably not what I'm looking for.

Splitting up long source code in several pieces (one per page) and put 
them in separate figures doesn't seem right to me. Setting it as 
numbered paragraph? Putting up a fake caption with \placefloatcaption 
(which doesn't seem to work in MkIV)? Are there other possiblities of 
numbering (by section) more or less big chunks of source code I'm not 
thinking of? That would help me very much. Thanks for thinking about that.

Best regards,
Stefan.

or width .. just experiment with values

you could move the framed to the right (\hskip1em or so) but on the 
other hand it might look more consistent if the numbers stick into some 
virtual margin

no page breaks indeed (at least not now in such cases)

you can make your own construct, maybe something with a background 
(textbackgrounds can cross pages)

Hello,

I use textbackgrounds to set-off paragraphs,
for example, here as secondary material.
It does not float and, indeed, may flow over many pages.

This is a concrete example (to which you could add line numbering):

\definetextbackground [secondary]
	[location=paragraph,
	background=color,backgroundscreen=middlegray,
	leftoffset=0.5cm,rightoffset=0.5cm,
	topoffset=.25ex,bottomoffset=.25ex,
	before={\blank[small]\switchtobodyfont[script]},
	after={\blank[small]},
	frame=off]
\kindofpagetextareas3 % fix from Hans
% Indeed, there are several internal methods available
% for managing text areas. Without this fix, the background
% color bleeds over footnotes and floats external to the
% secondary material.

\startsecondary
Here is some less interesting detailed stuff that can be skipped
if you wish…
\stopsecondary

Alan

Thanks, this is pretty nice. I'm going to use something like that inside 
an "algorithm enumeration", so I get the number I can reference to. This 
is better than the floating-approach, I think.

Thanks for the ideas,
Stefan.
