Folgenden Beitrag hab ich schon in einem anderen LaTeX-Forum gepostet, aber scheinbar kann (oder will ^^) mir da keiner helfen
Deshalb versuch ich es jetzt auch nochmal bei euch, vielleicht habt ihr ja ne Idee! =)
(Das Forum war auf Englisch, deshalb auch hier meine Frage auf Englisch, aber ich denke mal, das sollte kein Problem sein.
)I'm not quite a beginner, but it's the first time for me to go a little deeper
I'm wondering, how it's possible to continue an output-stream to write information out of an environment to a tmp-file.
Let me explain what I mean by a little example:
Inside a *.tex-file:
.
.
\newwrite\outputstream
\immediate\openout\outputstream=table.tmp
\begin{myEnvironment}[
Value1= 123,
Value2= 234,
Value3= true,
Value4= hello,
]
\end{myEnvironment}
.
.
\begin{myEnvironment}[
Value1= 678,
Value2= 789,
Value3= false,
Value4= bye bye,
]
\end{myEnvironment}
\immediate\closeout\outputstream
.
.
Inside a *.cls-file:
.
.
\def\myEnvironment@Value1{111}
\def\myEnvironment@Value2{111}
\def\myEnvironment@Value3{true}
\def\myEnvironment@Value4{words}
\define@key{myEnvironmentkey}{Value1}{\def\myEnvironment@Value1{#1}\immediate\write\outputstream{#1}}
\define@key{myEnvironmentkey}{Value2}{\def\myEnvironment@Value2{#1}\immediate\write\outputstream{#1}}
\define@key{myEnvironmentkey}{Value3}{\def\myEnvironment@Value3{#1}\immediate\write\outputstream{#1}}
\define@key{myEnvironmentkey}{Value4}{\def\myEnvironment@Value4{#1}\immediate\write\outputstream{#1}}
\newenvironment{myEnvironment}[1][mt]{\setkeys{myEnvironmentkey}{#1}
\paragraph*{\myEnvironment@Value1 , \myEnvironment@Value3 ... }
\noindent
\\
}
.
.
Now my real questions:
1st - How is it possible to write into an existing *.tmp-file without overwriting it?
This is the problem, when I put the I/O-stream into the definition of the new environment myEnvironment.
2nd - So, how can I move the lines with opening and closing the stream to the *.tmp-file from the *.tex to the *.cls and can I put them, as well as the concrete writing commands, inside the new environment?
The result should look like that:
table.tmp:
123
234
true
hello
678
789
false
bye bye
Thank you very much for a clue!!

Btw. this solution works! I just want to move the plain commands for opening and closing I/O to the *.cls, so they are hidden from the users for style reasons. Moreover I will need several *.tmp-files and moving the writing commands inside the environment would make it clearly arranged. =)[/code]
