how to reuse float numbers?

how to reuse float numbers?

[William S.]

Hello,

I am wondering if the float numbers can be reused for floats that are longer
than a page. I use floats that contain program segments (source code) for
a project report for my university studies.

The guidelines specify that captions for code which is longer than one page
or crosses page boundaries should be reprinted and the title changed to
(continued).

example:

Program Segment 1.1: Hello World
  #include <stdio.h>
  main() {

...on next page...

Program Segment 1.1: (continued)
    printf("hello world!\n");
  }

Can someone help me do this in ConTeXt? I think I can do the splitting of
the code myself if needed, but I don't know how to reuse the float number.
Currently this is how I define the float:

\definetyping[Program][blank=halfline]
\definefloat[ProgramSegment][ProgramSegments]
\setupcaption[ProgramSegment][location=top,align=right,headstyle=bold,style=bold,inbetween={}]
\setuplabeltext[en][ProgramSegment=Program Segment ]

And I use it like this:
\placeProgramSegment[here]{Hello World}
{
\startProgram
main() {
  printf("hello world!\n");
}
\stopProgram
}

Any help will be appreciated.

Thanks,
William.

you can start with the following example from Hans.

\definefloat[Exhibit][table]
\starttext
\input tufte\par
\splitfloat[lines=auto]{\placeExhibit{Knuth}}
{\dorecurse{4}{\input knuth \par}}
\input tufte\page[yes]
\stoptext

It says "there is nothing to split" at home and using ConTeXt live.
Thanks for the pointer to splitfloat. I'll investigate it using
ConTeXt's source code.

William.

Thank you! That's amazing...

It seems I need to learn more about writing these macros before I can
do anything like that. I almost decided to just use tables with no
frame to hold my source-code...

Thanks again!
William.

Thanks to Wolfgang's help the splitting problem is solved. However,
after the float is split, the captions get extra numbers (1.1.A,
1.1.B, etc).

I tried to "solve" this by using \setupfloatsplitting[conversions=...]
but even if I defined a conversion that prints nothing, the caption
would look like "Program Segment 1.1." (the final separator is still
printed).

I suppose a better way would be to override the command that makes the
captions (\setupcaption[ProgramSegment][command=...]) so that it
prints the real caption text in the first part, and "(continued)" in
the next parts.
However, I've searched the mailing list archive and I can't find an
example on what to put inside the command.

Can someone give me a clue as to what I should put inside the command
or maybe someone will have a better idea (maybe using
\setupfloatsplitting[inbetween=...])?

I've attached a slightly modified version of Wolfgang's document (I
added a conversion for the setupfloatsplitting).

Thanks,
William.

Hi William,

use

\setupfloatsplitting[conversions=numbers]

and

\setupcaptions[way=bytext]

The 1.1 is the normal float numbering, the 1, b, ... are the numbers
of every part of the splitted float.

This seems to be not supported but you can try to look into core-tsp.tex,
the module where float splitting is implemented.
