Re: [NTG-context] memoir-style chapter heading

19 Aug 2020

      Thank you Otared. The power of ConTeXt never ceases to amaze me, though 
despite the excellent work done on the wiki recently, it is the little 
things like the use of \raise that could be better described, especially 
in a range of applied instances. We find it, combined with hbox, in 
reference to marginal and centered headers, but it is not intuitive - 
for me at least - to be able to apply it as you have done in your 
example. The little process we have gone through, which is step-by-step, 
is most helpful, and I feel that I can now use these ideas in other 
instances and in slightly different ways. Thank you.

How important is the 'lohi' addition you made to \framed? I removed it 
to see what would happen and did not notice any appreciable difference 
in the output.

Hi Julian,
Actually one can tweak more or less the height at which the chapter number appears: below is an example in which one uses \raise and \hbox.
\setuppagenumbering[state=start,location=footer]
\setuphead[chapter]
  [
%	numberstyle={\switchtobodyfont[48pt]},
  numbercolor=gray,
  alternative=command,
  command=\MemoirChapter,
  ]
%\define[2]\MemoirChapter
%	{\startoverlay
%		{#1}
%		{#2}
%	\stopoverlay}
\define[2]\MemoirChapter
  {\framed[frame=off,width=broad,align={middle,lohi}]
      {\startoverlay
      	{\raise1.5ex\hbox{\switchtobodyfont[48pt]#1}}
      	{#2}
      \stopoverlay}
  }
\starttext
\startchapter[title={This is a test},ownnumber=1234]
\input knuth.tex
\stopchapter
\stoptext
Best regards: Otared

Thanks Otared - and whether using the earlier example (Aditya's with my minor 'centering' adjustment)) or yours, I agree - the number is just a bit too low, and of course, using this method we probably can't make adjustments to that. So ultimately it looks like I'll have to get my skills up to working with layers as well as overlays, where minute adjustments of the kind can be made. But wouldn't it be great if we could just do a bit of vertical adjustment in the overlay!

Hi Julian,
Indeed you can modify slightly what Aditya said to obtain what you want: you can put the overlay into a framed environment as in the following example. Though, to my taste the number is a little bit too low…
%% begin example
\setuppagenumbering[state=start,location=footer]
\setuphead[chapter]
  [
  numberstyle={\switchtobodyfont[48pt]},
  numbercolor=gray,
  alternative=command,
  command=\MemoirChapter,
  ]
\define[2]\MemoirChapter
  {\framed[frame=off,width=broad,align=middle]
      {\startoverlay
      	{#1}
      	{#2}
      \stopoverlay}
  }
\starttext
\startchapter[title={This is a test}]
\input knuth.tex
\stopchapter
\stoptext
%% end example
Best regards: Otared

I meant to include an example of what I mean, since at least it seems to work (am including just the definition part of your example), So at least I can get middle and right alignment.
\define[2]\MemoirChapter
  {\midaligned{\startoverlay
       {#1}
       {#2}
     \stopoverlay}}

Am completely new to using Metafun, which I presume I would need to use
to achieve a Hansen Memoir-style Chapter heading (chapter title
overlayed on a large lightgray number). Of course, I am assuming I would
need to use Metafun to create this...
So my first question is to ask if I could achieve the same effect
without Metafun?
I have read through the Metafun manual, and I think I can understand how
to overlay text on a graphic (MP), but it would be currently beyond me
to draw numbers of the kind we find in, say, the Memoir examples.
Has anyone created such an example? I was keenly looking for one in the
manual and elsewhere, in terms of ConTeXt/Metafun commands, but could
not find one. But I'd be quite prepared to 'have a go' at this, if I had
some pointers of just where to start! I assume I would have to
\defineoverlay[number] and then add text on top \framed (but without the
frame borders). Am I at least correct about this?
You don't need metafun for something this simple. Here is a crude implementation:
\setuphead[chapter]
           [
             numberstyle={\switchtobodyfont[48pt]},
             numbercolor=gray,
             alternative=command,
             command=\MemoirChapter,
           ]
\define[2]\MemoirChapter%
   {\startoverlay
       {#1}
       {#2}
     \stopoverlay}
   \starttext
\startchapter[title={This is a test}]
\stopchapter
\stoptext
Overlays don't allow tuning the location...for that you need layers. See the chapter on ornaments in the details manual, which also explains an alternative method to set title of chapters (toward the end of that chapter), which is useful if you need absolute positioning.
