Re: [NTG-context] system macros/doquadrupleemtpy

2008-09-04 Thread Thomas A. Schmitz
Aditya, Peter,

as always, thanks a lot for your help. Peter, you're certainly right  
that it's difficult to diagnose my problem - I'm sending only  
snippets, no example. But it's a fairly complex thing here for my  
presentation module and difficult to reduce in size.

 \Command2[#1][#2][#3]{4#}

 I thought this would be the way to go:

 \def\Command{%
  \doquadrupleempty\doCommand}

 You need something with possibly five arguments so you should use  
 quint
 rather than quad:

 \def\Command%
{\doquintupleargument\doCommand}

 \def\doCommand{%
  \iffifthargument%
  \doquadrupleargument\Command1%
  \else%
  \dotripleargument\Command2%
  \fi}


 The usual way is

 \def\doCommand[#1][#2][#3][#4][#5]%
{\doifelsenothing{#5}%See below
 {\Command1[#1][#2][#3][#4][#5]}
 {\Command2[#1][#2][#3][#4]}}

 I use \doifelsenothing rather than \doiffirthargument. If I give

 \Command[...][...][...][...][] with \doifelsenothing \Commnad2 will be
 called while with \iffifthargument \Command1 will be called. Use  
 whichever
 is more appropriate for your problem.

OK, that does make sense, but now I also see where my problem lies.  
When I define

\doCommand[#1][#2][#3][#4]#5

and then have

\Command2[#1][#2][#3]#4

TeX picks up a closing bracket as #4. I suspect that my problem lies  
in the definition \doCommand[#1][#2][#3][#4]#5 . The two definitions  
don't match; when I look at \doCommand, the closing bracket is indeed  
argument #4, from TeX's point of view. Maybe I need to reverse the  
order of my arguments and make it

\doCommand#1[#2][#3][#4][#5] ?

but I'm not sure if this would play with quintupleempty...

Anyway, thanks a lot for your help. I'll look further into it and will  
maybe come back with a real example later if I can't figure it out.

Re: [NTG-context] Verbatim with color background

 Hi,
 I have a short question about verbatim areas (\starttyping):
 
 I have been trying to define a background color to verbatim
 areas in a document. My method so far is to define a
 textbackground named verbatim and refer to this in the
 setuptyping method:
 
 \setuptyping[typing][margin=0.5cm,bodyfont=8.0pt,
 before={\starttextbackground[verbatim]},
 after={\stoptextbackground}]
 
 This works only partly. For example, when using long
 verbatim texts that spans over more than one page,
 the background color disappears on the last page.
 
 Is there any other easy way of controlling the background
 color on verbatim areas?

can you make a small example that shows where it goes wrong?

The example I used is shown below. Other observations are:

  - Removing the chapters in the test file also make it work with mkII

 Hi, Hans,

 the code works for MKII but not for MKIV. known issue or bug?

 and here comes the file.

in mkii:

- when you run out of fonts (due to randomization), then use a snapper:

vardef s(expr txt)=
h(txt, (ceiling(uniformdeviate(1)*100))/100);
enddef;

- use \forceMPTEXgraphictrue to make sure that the intermediate tex run 
takes place

in mkiv:

- in meta-pps, you can increment the number of reserved boxes ...

\appendtoks \MPLIBallocate{1000}\to \everydump

- also, remove the transparency spec since it will not work (you can use 
transparency in the text instead); for text + color to work i either 
need to make real ugly mp/lua code or wait till mplib supports multiple 
pre/postscripts

[NTG-context] frameoffset in textbackground

2008-09-04 Thread Wolfgang Werners-Lucchini
Hallo,

what is 'frameoffset' for? There seems to be no difference with and 
without this key.

--
\setupcolors[state=start]
\definetextbackground[strong]
  [backgroundcolor=lightgray,
   location=paragraph,
   frame=on,
   frameoffset=5mm]

\starttext
bla

\starttextbackground[strong]
zack
\stoptextbackground

blub
\stoptext
