I would like to request the restoration of labels (\definelabel) to
full citizenship in MKIV. While enumerations are more flexible in
many ways, they cannot replace one particular use of labels if find
necessary. Enumerations are paragraph entities, while labels are not
so restricted.
I use labels displayed as numbers in the margin to serially identify
quotations in a book about the development of quotation and
misquotation, at the same time generating reference information for
cross-referencing. While most quotations are blocks and can be
handled by enumerations, many are in-line quotations, and enumeration
cannot be used for these.
The wiki describes enumerations as the MKIV replacement for labels,
and the documentation as far as I can see omits \definelabel. Unless
there is something else supported in MKIV that can assume this
function of labels, can we please have full support for labels? I
would not want to see labels deprecated before the functionality is
reproduced.
(Of course, if you can suggest how enumeration can be adapted to this
requirement, or suggest an alternative mechanism, this request can be
rejected.)
two options:
\defineconstructionalternative
[mylabel]
[renderingsetup=constructionrenderings:mylabel,
width=]
\startsetups[constructionrenderings:mylabel]
\dontleavehmode
\flushconstructionheadbox
\stopsetups
\defineenumeration[two][alternative=mylabel,display=no,before=,after=]
\definelabel[foo][way=bychapter,prefix=chapter]
\starttext
\startchapter[title=bar]
here \starttwo\stoptwo \input tufte
here \foo[xx] \input tufte
whatever \in{foo}[xx]
\stopchapter
\stoptext
I played a bit more with enumerations and resolved one issue, I think.
The forced paragraph break is a feature of the default before/after keys
(both of which I need to null). Once this is done, enumerations can be
used for in-line text as well, and when an explicit \par is added to
\footnotes, the enumeration index appears there, unlike labels, where it
does not appear.
Can you explain why the enumeration defined with constructionalternative
rendering fails in footnotes, as shown in the following example? I
suspect it has to do with my not understanding the use of
\flushconstructionheadbox.
\defineconstructionalternative
[mylabel]
[renderingsetup=constructionrenderings:mylabel,
width=]
\startsetups[constructionrenderings:mylabel]
\inright{\dontleavehmode\flushconstructionheadbox}
\stopsetups
\defineenumeration[two][alternative=mylabel, % use mylabel rendering
headcolor=darkgreen,
text=, % no name preceding
label number
display=no, % suppresses line
break with constructs
before=, % no added text before
label number
after=] % no added text after
label number
\defineenumeration[why][alternative=inright, % use inright rendering
headcolor=blue,
display=yes, % seems to be the default
text=, % no name preceding
label number
before=, % no added text before
label number
after=] % no added text after
label number
\definelabel[foo][text=,headcolor=red,alternative=inright]
\starttext
\startchapter[title=bar]
here \starttwo[reference=aa]\stoptwo \input ward
\starttwo[reference=bb]\stoptwo \input ward
here as well?\footnote{\starttwo[reference=cc]\stoptwo This
fails.\par}
whatever \in{two}[aa] and \in{two}[bb] and \in{two}[cc]
\blank
here \two[dd]\input ward \two[ee]\input ward
here as well?\footnote{\two[ff]This fails.\par}
whatever \in{two}[dd] and \in{two}[ee] and \in{two}[ff] and why
is this section not three paragraph?
\blank
here \why[gg]\input ward \why[hh] \input ward
here as well?\footnote{\why[ii]This works!\par}
whatever \in{why}[gg] and \in{why}[hh] and \in{why}[ii]
\blank
here \foo[xx] \input ward \foo[yy] \input ward
here as well?\footnote{\foo[zz]This fails.}
whatever \in{foo}[xx] and \in{foo}[yy] and \in{foo}[zz]
\stopchapter
\stoptext
Could you explain the display key. The best I could determine from
strc-con.mkvi is that if it is not 'no' in a construction, a \par is
inserted, although I do not see why it is required in one case, and the
other in my example above.
Could you also explain why \par is required in the footnotes when it
does not seem to be needed in footnotes for any other use?
