[NTG-context] Re: simplify side by side Poems
Thanks so much
i also could define poem structure like this:
Using table method:
\protected\def\PoemStart#1\PoemStop
{\bTABLE[setups=tablepoem]#1\eTABLE}
\protected\def\Beyt#1
{\bTR #1 \eTR}
\protected\def\Misra#1
{\bTD #1 \eTD}
\starttext
\PoemStart
\Beyt{\Misra{the first sentence} \Misra{the second sentence}}
\Beyt{\Misra{the third sentence} \Misra{the fourth sentence}}
\PoemStop
\stoptext
also it can be done with itemize(easier but less flexible):
\defineitemgroup[Mypoem]
\setupitemgroup[Mypoem][horizontal,two]
\protected\def\PoemStart#1\PoemStop
{\startitemgroup[Mypoem]#1\stopitemgroup}
\protected\def\Misra#1
{\startitem#1\stopitem}
\starttext
\PoemStart
\Misra{the first sentence} \Misra{the second sentence}
\Misra{the third sentence} \Misra{the fourth sentence}
\PoemStop
\stoptext
there is also another method by using buffers and lua code (part of the answer
to my question on the stack site).

Thanks so much
but what should a person do if he wants to define an equivalent of \eTD?
for example it can be useful for RTL language
such as:
\def\پسل{\eTD}
and as you said this code will not work.
You can create your own replacement for the \bTD ... \eTD pair define a
command which is delimited by another command. To do this you have to
first create a new command like always as \def\... which takes a single
argument and at the end after the argument you another command is used
as delimiter for the argument.
The argument of your new delimited command is then passed to the normal
commands for the table cell.
begin example
\starttext
\protected\def\StartTableCell#1\StopTableCell
{\bTD#1\eTD}
% New method to create delimited arguments with #L and #R in Luametatex
%
% \protected\def\StartTableCell#L\StartTableCell#R\StopTableCell#1%
% {\bTD#1\eTD}
\bTABLE
\bTR
\StartTableCell row 1 column 1 \StopTableCell
\StartTableCell row 1 column 2 \StopTableCell
\eTR
\bTR
\StartTableCell row 2 column 1 \StopTableCell
\StartTableCell row 2 column 2 \StopTableCell
\eTR
\eTABLE
\stoptext
%%% end example

Hi all,
i want to use tables for constructing poems structure
this snippet of code works well:
\startsetups tablepoem
\setupTABLE[column][each][width=5cm]
\stopsetups
\starttext
\bTABLE[setups=tablepoem]
\bTR \bTD One one ons ksl \eTD \bTD two gfjgfd oski kwo \eTD \eTR
\bTR \bTD One wer s dft tgf \eTD \bTD two gfkdsjg dfs we \eTD \eTR
\eTABLE
\stoptext
but when i use this code for simplifying of changing cells I get an error:
\startsetups tablepoem
\setupTABLE[column][each][width=5cm]
\stopsetups
\def\Poemstart{\bTABLE[setups=tablepoem] \bTR \bTD}
\def\Mesra{\eTD \bTD}
\def\nextBeyt{\eTD\eTR\bTR\bTD}
\def\Poemstop{\eTD\eTR\eTABLE}
\starttext
\Poemstart
One one ons ksl\Mesratwo gfjgfd oski kwo \nextBeyt
One wer s dft tgf \Mesratwo gfkdsjg dfs we
\Poemstop
\stoptext
what is the problem?
The table environment collects the content of the table cell-wise which
means when TeX sees a \bTD in the input it reads the following text
until it finds the corresponding \eTD. When you put the \eTD in the
definition of another command the scanner will never find the end of a
cell and you either run out of memory or reach the end of the file etc.
Below are a few alternative solutions to simplify the input, one of them
is an alternative version of input (\startTABLE) for natural tables
which uses the same commands to separate columns as tabulate does.
begin example
\starttext
\startTABLE[width=5cm]
\NC One one ons ksl \NC two gfjgfd oski kwo \NC\NR
\NC One wer s dft tgf \NC two gfkdsjg dfs we \NC\NR
\stopTABLE
\starttabulate[|*{2}{k{0}lw(5cm)|}]
\NC One one ons ksl \NC two gfjgfd oski kwo \NC\NR
\NC One wer s dft tgf \NC two gfkdsjg dfs we \NC\NR
\stoptabulate
\defineparagraphs[poem][n=2,width=5cm]
\setupparagraphs[poem][each][width=5cm,distance=0pt]
\startpoem
\startlines
One one ons ksl
One wer s dft tgf
\stoplines
\nextpoem
\startlines
two gfjgfd oski kwo
two gfkdsjg dfs we
\stoplines
\stoppoem
\stoptext
end example
