Recursive printing letters using Letters module...

Recursive printing letters using Letters module...

[Jaroslav Hajtmar]

Hello,
Can be deployed print letters due t-letter module in the cycle?
When I use recursion, then an error occurs.
I note that I am going to change the values (from CSV file) in a cycle 
(that someone thought that I want to write a few the same letters in 
cycle  :-)

here is my example:

\usemodule[letter]

\starttext

\dorecurse{5}{
\startletter[
         toname={Name},
         toaddress={Address},
         opening={Dear Name,},
         subject={Step by step guide to write a letter},
         closing={Greetings from the Author}]

     Thus, I came to the conclusion ...

     \stopletter
\page
}

\stoptext


Thanx, Jaroslav

Hello
I answer it yourself. I was experimented and thought about using buffers 
and the problem is successfully for my library resolved :-)
I think that I found an interesting use of the letter module...

Jaroslav

Only for example :


\directlua{dofile("scancsv.lua")}

\setupcolors[state=start]
\usemodule[letter]

\setupletter
[fromname={The Author},
fromaddress={Hidden Street 2\\57895 Mystery town}]



\startbuffer[myletter]
\startletter[
     toname={\Firstname\ \Name},
     toaddress={\Street\\ \Zipcode\ \Town},
     opening={Dear \Firstname,},
     subject={Step by step guide to write a letter to \Firstname\ \Name},
     closing={{\color Greetings from the Author} to \Name\ \Firstname}]

Thus, I came to the conclusion ... \Mygreeting

\stopletter
\stopbuffer



\starttext
\setheader
\opencsvfile{file1.csv}

% Recurse using
\dorecurse{5}{
\getbuffer[myletter]
\nextrow
\page
}

\page
% Or loop cycle

\opencsvfile{file2.csv}
\doloop{\ifnotEOF\getbuffer[myletter]\nextrow\else\exitloop\fi} %OK

\stoptext

You can’t use buffers inside \dorecurse and the letter environment
is a buffer with a few extension to accept a argument for values.

You can get around this with the alternative mode for the environment
with is enabled by:

\setupletterstyle[option][method=content] % \setupletteroptions[method=content]

\dorecurse{5}
  {...
   \startletter
     [toname={\Firstname\ \Name},
      toaddress={\street\\\Zipcode\ \Town},
      ...]
   This, I came to the conclusion … \Mygreeting
   \stopletter
   ...}

The disadvantage is that \startlines or \starttyping can't be used anymore
inside of a letter.


The second method you can use is to drop the letter environment and set
the values for the address and name with \setupletter and store the content
with the lettercontent environment (just a names buffer). The letter itself
can now be flushed with \setups[letter:place].

\setupletter
  [toname={\Firstname\ \Name},
   toaddress={\street\\\Zipcode\ \Town},
   ...]

\startlettercontent
This, I came to the conclusion … \Mygreeting
\stoplettercontent

\dorecurse{5}{...\setups[letter:place]...}

Hello, Wolfgang,
thanked for alternative solutions. While saying that the use of the 
buffers is not possible, but even though you do not seem to really work 
with my scancsv.lua library, and even very good! With the help of my 
library and your letter module I can print dozens of similar letters 
which differ only certain data. Thanks for your letter module - very 
helps me

Jaroslav

I hadn't used your module in my example because

1. I don't have access to the module,

2. I doesn't matter where the data comes from, you can input the data
   for a serial letter from TeX, XML, Lua or whatever else you use,
   the important thing is to know how to deal with the restriction
   of buffers (what the letter environment is).  It isn't also
   necessary to rely on the letter environment and the \setupletter
   commands because you can use all the available setups environments
   (I should document this) without problems.

Thanx Wolfgang,
Now everything is OK, your module t-letter works with my Lua library 
very well and without any obvious limit.
I will demonstrate it at COnTeXtmeeting in Brejlov.
