Writing into file -nemerle

[David Ben-Michael]

I want to read text from a file, line by line, and for each line - write it at new file.

:I use the following instruction System.IO.File.AppendAllText(@"C:\Users\David Ben Michael\source\repos\nemerle\files\output.asm",line);

.The problem with this code it that the text attched to the file at  a one long line:

: I wish to separate the lines. So Instead of using the instruction above,I used the following code: 

 if (fileExt == ".vm" )
      {
          def sr = System.IO.StreamReader(fi.FullName);
          def sw =System.IO.StreamWriter(@"C:\Users\David Ben Michael\source\repos\nemerle\files\output.asm");
          mutable line = sr.ReadLine ();


    while (line != null) { 
        sw.WriteLine(line);
    //System.IO.File.AppendAllText(@"C:\Users\David Ben Michael\source\repos\nemerle\files\output.asm",line);

     line = sr.ReadLine ();

At this case, the compiler create empty file(!). Why the file is empty? and how I resolved this problem?

Thanks

Hi David!

1) The easiest way to do what you want is

System.IO.File.AppendAllText(@"C:\Users\David Ben Michael\source\repos\nemerle\files\output.asm",line + System.Environment.NewLine); // notice the NewLine stuff

2) I don't see any calls to Flush(), Close() or Dispose() in your second sample. This might be one of the reasons it does not work.

Hope that helps and good luck with learning Nemerle.
