blocks in itemize

blocks in itemize

[Rob Ermers]

Dear Contexers,

I am setting up a complex bilingual document, which has to print one 
language at the time.

Does anyone know how to use the wonderful blocks application in an 
itemize environment? I think the second block causes problems.

Kind regards,

Robert

\endNederlandsblok

\beginEngelsblok
\item  I really wonder if they do sell apples %ENG
\endEngelsblok
\stopitemize
\stoptext

Don't putn them in, but around the itemize:

   \beginNederlandsblok
   \startitemize
   \item Ik vraag me af of ze ook appels verkopen %NED
   \stopitemize
   \endNederlandsblok

Thanks Taco,

I have of course thought of that, and I know it must work, but in the way I intend to set up the document, especially in regard to the connections between the blocks (item A' = translation of item A), it would be handy if it could be done around each item.

If not, I'll have to find another solution.

Kind regards,

Robert

Why not just use a lot of one-item itemizes?

Hi Olivier,

Thanks for your reaction. My original proposal was:

\startitemize
  \beginblockA
    \item Apple
  \endblockA
  \beginblockB
    \item Pomme
  \endBlockB
  \beginblockA
    \item Pear
  \endblockA
  \beginblockB
    \item Poire
  \endBlockB
\stopitemize

This does not work.

The advantage of this setup is that in a bilingual document, printed separatedly, I have both languages underneath and thus more control than when I use separate itemize environments, such as proposed by Taco, and what I had thought of earlier:

\beginblockA
\startitemize
....
\stopitemize
\endblockA

\beginblockB
\startitemize
....
\stopitemize
\endblockB

Nevertheless, if my proposal does not work, I guess I'll have to try it this way.

Kind regards,

Rob

I don't know anything about how blocks work, so this may be completely 
off-base, but if they do any sort of grouping, that would be quite 
sufficient to cause problems in a situation like that.  Does this work?

\startitemize
   \item \beginblockA
     Apple
   \endblockA
   \item \beginblockB
     Pomme
   \endBlockB
   \item \beginblockA
     Pear
   \endblockA
   \item \beginblockB
     Poire
   \endBlockB
\stopitemize

Re: Re: blocks in itemize

[Rob Ermers]

Thanks Brooks and Olivier,
I'm afraid the problem has not entirely been solved.

Brooks' solution works in the sense that I can hide BlockA or B 
(\hideblocks[BlockA]), but the \items remain, and empty items are generated.

Olivier's suggestion is processed, the result is only one language. Now 
now I wonder how to hide either one of the languages. The document I 
want to produce is monolingual, either Dutch or English.

Thanks again!

Kind regards,

Robert

Re: Re: blocks in itemize

[Rob Ermers]

Hi,

If I make sure there is enough space, i.e. more than one space, between 
the \begin... and the text, it works! However in the pdf the item drops 
a line down, like this:


*
     Ik vraag me af ...

Does anyone have a workaround?

Kind regards,

Robert

Does
     \setupblock[Nederlandsblok][before=,after=]
     \setupblock[Engelsblok][before=,after=]
solve your problem?

Besides that, I would prefer to define something like
   \def\NlEn#1#2{%
     \beginNederlandsblok%
       {#1}%
     \endNederlandsblok%
     \beginEngelsblok%
       {#2}%
     \endEngelsblok}

in your case, but you should ask someone else why this doesn't work (I 
guess it's some strange expansion problem again - I never understood 
that topic).

Another extremely lightweight TeX solution:

\newif\ifenglish
\englishtrue % \englishfalse

\def\NlEn#1#2{\ifenglish{#2}\else{#1}\fi}
\starttext
\NlEn{Dutch}{English}
\stoptext

However, if you want to have more complex stuff in it, you probably have 
to use a more complex definition (send an exaple that fails).

[Rob Ermers]

Hi everybody,

The solution below works. Thanks a lot!

Using Mojca's solution plus a newline after the command apparently does 
the trick.

After that, I didn't try the other solution, which resembles Olivier's.

Kind regards,

Robert

because there is parsing involved (how else to determine the end condition 

you may try:
