Overriding the number on a float

Overriding the number on a float

[Duncan Hothersall]

[-- Attachment #1.1: Type: text/plain, Size: 1002 bytes --]

I think there was a question on this very recently but I don;t think it got
an answer and I can't find it to reply to, so apologies for the extra
noise. I have a large text with floats numbered sequentially by chapter and
then figure/table number, but at the last minute I've had a request for two
figures in a particular chapter to become 27.1a and 27.1b instead of 27.1
and 27.2. It's not a combination - they are separate figures on different
pages.

I've experimented with the options I can see, but it's not obvious if there
is a facility to override the numbering of two figures in a stream of
normally numbered figures like this. I was thinking of the equivalent of
the old \sym{symbol} command that used to work as a way to override a
single item in an otherwise sequential list.

I guess there's a brute force method of setting up a new type of figure
with the label "Figure 27.1" and having them numbered as lowercase alpha,
but if there's an easier way that would be great.

Thanks.

Duncan

I’m also interested in overriding automatical numbering, e.g. of chapters or itemization items.

E.g. in my songbook, I’d like to have the verses numbered but interrupted by a chorus numbered as "C" (i.e. "R" in German).
Similarly the paragraphs of some (by)laws that were changed a lot and use a numbering like 1, 2, 3, 3a, 4, 7...

Something like
\startitem[number={R}]
or
\startsection[number={3a}]
would be nice.
If I set it to an integer, ConTeXt should set the counter accordingly, otherwise continue counting from the previous calculated number. Would that be possible?

BTW do sections, items and floats all use counters (\setnumber/\getnumber) or other mechanisms?

You can set your own section numbers but the counter isn't stopped.

\starttext

\startsection[title=One]
\stopsection

\startsection[title=Two]
\stopsection

\startsection[ownnumber=X,title=???]
\stopsection

\startsection[title=Three]
\stopsection

\stoptext

Thank you! I overlooked "ownnumber". It works for sections, but not for items or floats.

\setnumber[section][10] doesn’t work, \setcounter the same (according to the source they’re synonymous) – does section use a different counter name or is it no counter at all?

\setnumber[figure][10] works (but only with integers, not some alphanumerical stuff, sorry Duncan).

\setupnumber is a synonym of \setupcounter and exists for backwards 
compatibility.

For this subfigure stuff, perhaps this is useful?

% setup definitions
\definecounter[subfigure][way=bytext,prefix=no]
\setupcounter[subfigure][state=start,numberconversion=a]
\setcounter[subfigure][1]

\def\setsubfigures
  {\setcounter[subfigure][1]
   \incrementcounter[figure]
   \setupcaption[figure][state=stop,numberstopper={\convertedcounter[subfigure]}]}

\def\unsetsubfigures
  {\setupcaption[figure][state=start,numberstopper=]}

%usage
\setsubfigures

\startplacefigure[title=Test figure]
\externalfigure[dummy]
\stopplacefigure

\incrementnumber[subfigure]

\startplacefigure[title=Test another figure]
\externalfigure[dummy]
\stopplacefigure

\unsetsubfigures


I could not find a safe way to increment the subfigure number automatically, unfortunately.

Best wishes,
Taco

Thanks all for useful tips. I ended up doing something similar as a short
term fix for my float number override issue, basically setting up a new
float type to use for the deviant ones and then resetting the numbering of
the existing ones. It would be great if there was a facility to just drop
in an override on an individual float using the equivalent of
ownnumber={27.1b}, but I appreciate this may be much more complex under the
hood than it seems to a mere mortal. Certainly my brief perusal of the
sources left me baffled, as usual!

Thanks again.

Duncan

Another option is to define:

\startplacesubfigure ... \stopplacesubfigure

which could use the current value of figure counter as prefix and increment the subfigure counter. Something similar is there for subformulas in the math mode, but I'll have to go back and check the implementation details.
