In my version of 'In the Details', dated 2002 chapter 1 deals with 
'Snapping section heads' and section 1.8 is titled 'Snapping around 
(broad,high,depth).' 
Is there a newer variant of that manual?

Must be, I read mine online from

   http://www.pragma-ade.com/general/manuals/details.pdf

while I was keying in this answer.

the grid options as discussed with sections, are the ones that are taken care of by the \snaptogrid macro; the grid key in externalfigure is not related to that, it relates to scaling, as in

\setuplayout[grid=yes] \showgrid \setupcaptions[style=smallbodyfont,location=grid,inbetween=]

\defineexternalfigure[enkel] [width=10cm,frame=on,grid=depth]
\defineexternalfigure[dubbel][width=10cm,frame=on,grid=depth]

\starttext

test \placefigure{}                 {\externalfigure[t:/sources/cow.pdf][frame=on,grid=yes]} test \page
test \placefigure{\input zapf\relax}{\externalfigure[t:/sources/cow.pdf][frame=on,grid=yes]} test \page

test \placefigure{}                 {\externalfigure[t:/sources/cow.pdf][enkel]} test \page
test \placefigure{\input zapf\relax}{\externalfigure[t:/sources/cow.pdf][enkel]} test \page

\stoptext

i.e. the grid option determins which way a height snaps (or is rounded);

Ahh! I see!
So '\{' is a table command NOT a FormatKey? 

But why is '\{' introduced in 'thrd-tab.tex' with 
\NewFormatKey \{{..} as a primitive key?

The wikiwriter has obviously used this source too.

\arg{bla} gives me 'argbla'!

I have no idea what it is used for. Using it in math environment
$\arg{bla}$ gives me

"arg {\it bla}"

which is much better than 'argbla'. I guess it's a math only macro.

Some questions

[Alain Delmotte]

  Hi,

  Now some questions to solve the problems I have when I try 
to follow the "tutorial" "ConTeXt an excursion".
  I think it is for mkII and I use mkIV and that there has 
been many changes in between.

  - The example at the bottom of page 11 and page 12 gives 
me an error:
  ! Argument of \head has an extra }.

system          > tex > error on line 52 in file 
travail.tex: Argument of  ...

42     Hasselt lies in the province of Overijssel and there 
are a number of customs that are typical of this province.
43     \startitemize
44     \head kraamschudden \hfill (child welcoming)
45     When a child is born the neighbours come to visit the 
new parents. The women come to admire the baby and the men 
come to judge the baby (if it is a boy) if he will become a 
strong man.
46     The neighbours will bring a {\em krentenwegge} along. 
A krentenwegge is a loaf of currant bread of about 1 \Meter\ 
long. Of course the birth is celebrated with {\em jenever}.
47     \head nabuurschap (naberschop) \hfill (neighbourship)
48     Smaller communities used to be very dependent on the 
cooperation among the members for their well being. Members 
of the {\em nabuurschap} helped each other in difficult 
times during harvest times, funerals or any hardship that 
fell upon the community.
49     \head Abraham \& Sarah  \hfill (identical)
50     When people turn 50 in Hasselt it is said that they 
see Abraham or Sarah. The custom is to give these people a 
{\em speculaas} Abraham or a Sarah. Speculaas is a kind of 
hard spiced biscuit.
51     \stopitemize
52 >>

- The tables pages 30-31-32-35 are not at the right position 
on the page, mostly they are to the right and not centered.

- The chemical formulae give an error (pages 37-38), but 
I'll come back to that later on, but what is the manual 
about it?

- The boxes on page 45, second example are not at the right 
position, particularly the second is on the same line as the 
first.
\leftaligned
{\inframed[width=fit]{People in Hasselt}}
\midaligned
{\inframed[height=1.5cm,frame=off]{have a}}
\rightaligned
{\inframed[background=screen]{historic background}}

What are the up todate manuals for MkIV?

OK It's enough bothering you for the moment.

Thanks in advance,

Alain Delmotte

I did not try all example, but this seems to work here. Can you
provide a minimal example and say what you expect to be different?

Hans and Alan are in the process of completely re-writing the
chemical macros. I don't know the current state.

In MkIV there's a new syntax you can use:

\startlinealignment [left]
  \inframed[width=fit]{People in Hasselt}
\stoplinealignment

\startlinealignment [middle]
  \inframed[height=1.5cm,frame=on]{have a}
\stoplinealignment

\startlinealignment [right]
  \inframed[background=screen]{historic background}
\stoplinealignment

I did not investigate why the middle alignment is on the same line
as the left alignment and if that's intended or not.

> What are the up todate manuals for MkIV?

I'm afraid there are none (and probably never will be). The wiki
improved an awful lot during the last months, especially the command
reference. There's also the revised manual, tex.stackexchange and of
course the mailing list.

I have written a new manual that will be made available (soon),
once I manage to find some time with Hans to finish a few points...

I see that in the example from the ConTeXt Excursion manual, PB:...PE currently gives some errors.
I will look into this this weekend (I prefer to use SAVE...RESTORE, but I see that it is indeed
important to keep PB:...PE working to insure some backwards compatibility).

In another example before, the locations for floats was 
changed to right and so all tables where to the right, 
except the last which had a location=left.

OK, it works, but I do not get the result of the book, I'll 
investigate.

Waiting the book announced by Alan, I'll try to use the wiki 
and existing modified books.

Thanks a lot for your help,

A manual *only* describing the chemical macros...
perhaps to be considered as a chapter of the official documentation...

\arg is one of the verbatim macros, like \type, \typ, \tex
and is describte in 'cont-enp.pdf' on page 101.

The description looks a bit incomplete: (the command encloses the 
text with .)
(Can someone, with the right to do that, add this to the list of 
typos, please?)

The definition of \arg is in 'core-ver.tex' and copying this 
in a separate file works as expected:

\starttext
\unprotect
\def\setgroupedtype
  {\let\currenttypingclass\??ty
   \initializetype
   \catcode`\{=\@@begingroup
   \catcode`\}=\@@endgroup}

\unexpanded\def\arg{%
\groupedcommand{\setgroupedtype\leftargument}{\rightargument}}
\protect
\arg{bla}
\stoptext

So there must something be damaged.

Well, \arg is also defined in math-tex.tex:

   \definemathcommand [arg]     [nolop] {\mfunction{arg}}

So there is a double definition.

[wwl]

Hallo!

After reading some manuals, I have some questions.
May be I have not understand it right.

Try the following example:
---------------------------
\setupcolors[state=start]
\starttext
How can I use the brace-key right?
\starttable[| \{ |]
\NC no braces \SR
\stoptable

What I am doing wrong here?
\starttable[ o1 | C{red} |]
\VL red \VL\SR
\stoptable
red too!

Should'nt \arg{bla} be \type{{bla}}?

the wiki entry is not that clear ("enclose the column in braces").
\{ is a just a grouping command (which directly gives a solution for
your second answer)

Use
  [| a{\{}b{\}} |]

to add "braces"

I can't give you a satisfying answer for this, but

Should'nt \expandafter\type\expandafter{\arg{bla}} be \type{{bla}}?

gives

Should’nt \dohandlemathtokenarg{bla} be {bla}?

(so I guess the answer is probably no)

Some questions

[David Arnold]

Hans, All,

I've seen this before:

\setuphead
 [chapter,section]
 [style=\bfb,
  before=,
  after={\blank[3*medium]},
  align={right,broad},
  number=no]

What does before=, accomplish? Why not just write

\setuphead
 [chapter,section]
 [style=\bfb,
  after={\blank[3*medium]},
  align={right,broad},
  number=no]

What would be the difference? Also, align={right,broad}. I know what right
does, but what does broad add in this case?

before is only used when one does not force a new page (with page=...).
When a section comes after a chapter, the before is executed, but the
biggest white space (if set) takes precedence.

>What would be the difference? Also, align={right,broad}. I know what right

It influences the last line as well as more alignments in a row (more
homogenous).
