Below is a different solution to your problem with works without 
\startlines because you already mark up each individual line in the poem 
which make it possible to add a linebreak in the output.


With \blank options (samepage) you can avoid pagebreaks between stanzas.

\startxmlsetups xml:test
\xmlsetsetup{#1}{*}{-}
\xmlsetsetup{#1}{doc|poem|stanza|line}{xml:*}
\stopxmlsetups

\xmlregistersetup{xml:test}

\startxmlsetups xml:doc
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:poem
\blank[line]
\xmlflush{#1}
\blank[back,line]
\stopxmlsetups

\startxmlsetups xml:stanza
   \xmlflush{#1}\blank[preference,line]
\stopxmlsetups

\startxmlsetups xml:line
\xmlflush{#1}\blank[samepage,none]
\stopxmlsetups

\startbuffer[test]

[NTG-context] Re: Define a new command that inherits from multiple other command options

2024-04-26 Thread ai2472206007 
Thanks for your reply. 

The kanji part requires a specific font and typescript file, which I defined on 
my own computer but forgot to add to this example. This is something I didn't 
take into account. It's true, I need to think about what exactly my command 
needs, not build an all-powerful command. It's my poor consideration.

Your example didn't work for me - none of the Chinese|Japanese[1] characters 
showed.

AFAIK there is no way to "inherit" functionality.

You still need to write \setupsidenote to call \setupcounter, \setupframed at 
the right points to achieve the right effects.

What you can do is have \setupsidenote accept all options in one big long list 
and then pass the ones that apply to setupcounter to each use of \setupcounter, 
pass on the ones that apply to setupframed to each use of \setupframed and so 
on.

Thsi is releatively easy in Lua where you could define a list of all possible 
commands and which macro they apply to then loop through it looking to see if 
that option had been supplied and building a set of parameters for 
\setupframed, \setupcounter etc.

Hope this makes sense.

But I feel there's probably a better way - it's a lot of effort to go to in 
order to have a single "does it all macro" instead of calling two or three 
macros each time.

Regards,

[1] Apologies for my ignorance.

Crappy code:

  \starttext
  a\dorecurse{25}{\par}b
  a\dorecurse{25}{\null\par}b
  \stoptext

Just to show it could be achieved,

There is nothing wrong, this is just a side effect of the scanner used

behavior use the \tolerant modifier for \def to change it.


Many thanks for your reply, Wolfgang.

I tried this approach (I hope it isn’t wrong):

   \starttext
   \expanded\tolerant\def\MyCommand#_#,#_#,#_#,#_{%
 \doiftextelse{#4}%
   {#4}
   {\doiftextelse{#3}

The \expanded modifier is wrong (I guess you meant \unexpanded) but 
which check for the number of arguments you use doesn't matter in a 
document.


The LMTX version of the \iffourthargument etc. checks is the 
\ifarguments commands where you use \or to set a case for the number of 
argument passed.


\protected\tolerant\def\MyCommand#_#,#_#,#_#,#_%
  {\ifarguments
 % no arguments are passed
   \or
 #1% one argument is passed
   \or
 #2% two arguments are passed
   \or
 #3% three arguments are passed
   \or
 #4% four arguments are passed
   \fi}



   \MyCommand{}{second}{third}{fourth},\\
   \MyCommand{}{second}{third}{fourth} e,\\

   \MyCommand{}{second}{third},\\
   \MyCommand{}{second}{third} e,\\

   \MyCommand{}{second},\\
   \MyCommand{}{second} e,\\
   \stoptext

BTW, this is the first time I see #_ instead of #1.

There is no way to search for "#_" in the wiki.

Grepping the source, "#_" seems to be used for optional arguments
(mainly in syst-aux.mkxl).

But what are these "#_" (which don’t seem to come from TeX)?


Hans added many additions to command parameters in Luametatex and #_ 
means the argument to a commands has to be enclosed in braces while #1

allows you to pass text without it.

In the following example \CommandA take in the first case "a" as 
argument while CommandB ignores it and would only accept "{a}" with 
braces around it.


 begin example
 \def\CommandA#1{(#1)}
\tolerant\def\CommandB#_{(#1)}

\starttext

\CommandA abc\par
\CommandB abc\blank

\CommandA {ab}c\par
\CommandB {ab}c\blank

\stoptext
 end example

You can find a list with all new command parameters in lowlevel-macros.pdf.

Another way to avoid this is to create a command with a key-value list.

\tolerant\def\Command[#1]%

   \getdummyparameters[#1]%
   \doifsomething{\dummyparameter{a}}{(\dummyparameter{a})}%
   \doifsomething{\dummyparameter{b}}{(\dummyparameter{b})}%
   \doifsomething{\dummyparameter{c}}{(\dummyparameter{c})}%
   \doifsomething{\dummyparameter{d}}{(\dummyparameter{d})}%
   \endgroup}

\starttext

\Command[a=1,b=2,c=3,d=4] xxx\par
\Command[a=1,c=3] xxx\par

\stoptext
 end example

   Thanks for your answer and sorry for not being clearer. I was just wondering why the \par seems to have no effect. (I first guessed that it might be related to XML, to but then realized it happens with context markup as well. Usually, you won't run into this because an empty line works, but with XML that's not am option.) As you've said, it looks like a bug then.
   
  
    
   
  
   Thanks,

[NTG-context] wrong spacing after command with optional arguments

2024-04-26 Thread Pablo Rodriguez via ntg-context 
Dear list,

I have the following sample:

  \starttext
  \def\MyCommand{\doquadruplegroupempty\doMyCommand}

  \def\doMyCommand#1#2#3#4{%
\iffourthargument
  #4%
\orelse\ifthirdargument
  #3%
\else
  #2%
\fi}

  \MyCommand{}{second}{third}{fourth},\\
  \MyCommand{}{second}{third}{fourth} e,\\

  \MyCommand{}{second}{third},\\
  \MyCommand{}{second}{third} e,\\

  \MyCommand{}{second},\\
  \MyCommand{}{second} e,\\
  \stoptext

I don‘t know why only the command gets the space after right only when
the four arguments are provided.

What is wrong in my definition above?

Many thanks for your help,

Pablo

Hi Denis,

MkIV with \par works in your sample and LMTX with \par doesn’t.

[NTG-context] \par and \startlines

How can this be done?

[NTG-context] Re: The graph is not visible.

2024-04-26 Thread Fabrice Couvreur 
Hi,
Thanks for your help. I did several tests playing only with the code of
component 5 which interferes with that of component 14.

@Aditya
begingroup;
.
endgroup;
does not work.

@Hans
save defaultfont, defaultscale;

maybe also:

save circle, p, q, b ;

I get an empty rectangle in place of the graph in composant 5.

@Taco
The solution that works is to add component 14 to the code

numeric a, b;

Woundn't newnumeric be better? 

There are very few instances where I want variables defined in one block to be 
reused in another block. So, I almost always use

\startMPcode
begingroup;

endgroup;
\stopMPcode

to avoid such issues.

Because of this “path b”:

which interferes with the assignment line from the other graphic code:

because there “b” is a now a path, not a numeric.

Adding 

   numeric a,b;

fixes the problem in chapter 14. 

But why it does not affect chapters 6-13, that I do not understand.
