How would you approach serial letters, e.g. to all members of a club?
(Actually I need to send out donation receipts.)
I’d like to use the letter module, since my usual letter design is using it.
I can export the addresses to CSV, JSON, Lua tables or whatever or transfer them to a SQLite db.
Would it make more sense to read them in Lua and combine this data with a buffer, or to write a single tex file for every letter?
I know how to do the latter, but I’d like to learn a more ConTeXt-ish way.
Would it make sense to use the bibliographies module?
I have the same need. I tried a basic solution:
======================= Start failing example
\usemodule[letter]
\setupletter[
   signature={JPR},
   closing={Sincerely yours,}
   ]
\def\GenLetter[#1]{
   \getparameters[GL][#1]
   \startletter[
      toname={\GLto},
      toaddress={\GLadr},
      opening={\GLciv},
      ]
Blah blah \GLciv.
\stopletter
}
\starttext
\GenLetter[civ={M.}, to={Pierre Durand}, adr={Trifouillis-les-Oies}]
\stoptext
======================= End failing example
My idea being to generate as many letters I like by multiplying the \GenLetter line.
However, I get an error message I don’t understand. Can someone point to the thing I am doing wrong ?
The problem is that you put the letter-environment in a command but the 
environment uses the buffer mechanism to store the content which doesn't 
work when it is used in a command definition.
What you have to do is to move the content of the letters out of the 
\GenLetter command, you can use the lettercontent-environment for this. 
In the \GenLetter command you now use the \placeletter command to flush 
the content of the letter with the current values for the address etc.

%%%% begin example
\usemodule[letter]

\setupletter
   [signature={JPR},
      closing={Sincerely yours,}]

\setupletter
   [   toname=\correspondenceparameter{to},
    toaddress=\correspondenceparameter{adr},
      opening=\correspondenceparameter{civ}]

\startlettercontent
   Blah blah \correspondenceparameter{civ}.
\stoplettercontent

\def\GenLetter[#1]%
   {\begingroup
      \setupletter[#1]%
      \placeletter
    \endgroup}

\starttext

\GenLetter[civ={M.}, to={Pierre Durand}, adr={Trifouillis-les-Oies}]

\stoptext
%%%% end example
