[Tex/LaTex] how to force TeX to keep line breaks

line-breakingmacros

I would like to write a programme code to a file, so that it can be later on executed. The language requires to keep line breaks.

\begin{myCode}
one
two
three
\end{myCode}

In my macro I have following

\obeylines

which produces this output:

one^^Mtwo^^Mthree

Is there a simple way how to replace ^^M by a line ending character that would by recognized by a Unix system? I understood that verbatim environment processes text line by line, but in this case it's probably not necessary.

Update:

Here's the minimal working code:

\documentclass{minimal}
\usepackage{environ}

\newwrite\myOutput
\makeatletter

\def\my@writeToFile#1{
  \immediate\openout\myOutput=output.txt%
  \immediate\write\myOutput{#1}
  \immediate\closeout\myOutput
}

\newenvironment{myCode} {
    \obeylines
    \Collect@Body\my@writeToFile %macro from the environ package
}{%
}
\makeatother

\begin{document}
  \begin{myCode}
  one
  two
  three
  \end{myCode}
\end{document}

Best Answer

\newlinechar`\^^J

will make it put unix line end control J at the ends instead of control M,
