[Texmacs-dev] CR/LF endings with Windows sessions under Cygwin TeXmacs

[Andreas Seidl]

I run a PSL-REDUCE for Windows session under Cygwin TeXmacs. (This works 
since recently, as a very old bug in Winows PSL Lisp was fixed by Winfried 
Neun.) Unfortunately, at line endings a comma occurs. See 
http://www.fmi.uni-passau.de/~seidl/public/bin/test.pdf .

My suspicion was that the reason for this is that there are CR/LF line 
endings comming from the Windows application, while TeXmacs expects LF 
only. Indeed, by writing a little C program (see below) that swallows the 
CR the problem vanishes.

I want to raise the question, if caring for line endings can be 
incorporated into the TeXmacs code for session handling somewhere.

As for Mac, no action is required, as meanwhile it uses Unix line endings 
as well, I was told.

Best Regards,
Andreas

    c = getchar();
    if (c == EOF)
      break;
    if (c == 0x0d)
      // putchar('R');
      n=0;
    else
      putchar(c);
    fflush(stdout);
  }
}
