some questions

[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}}?
\stoptext
------------------------

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"

                    \{C{red}

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)

A manual *only* describing the chemical macros...

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,

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).

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.

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

about it?

- The boxes on page 45, second example are not at the right

first.

OK It's enough bothering you for the moment.

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

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

So there is a double definition.

\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.

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.

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'!

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.

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

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?
