     File("data.txt", "r+")

byLineCopy removes the new lines. If in the future you would need 
the new line symbol call byLineCopy(Yes.keepTerminator)

Sorry but not working ... Surely i'm not able to insert and adapt

Could you, please, modify with the right syntax at the right 
place ? - Thanks.

 Thanks.

The following program works for me.

As I'm on Linux, I had to write a makeFile() function to generate the=20
file to ensure '\r' line endings. (Otherwise I would get '\n'.)

'result's type is string.

import std.stdio;
import std.file;
import std.algorithm : each, joiner, map;
import std.array : array, empty;
import std.conv : text;
import std.typecons : No;

void makeFile(string fileName) {
   const lines =3D ["abcd", "1234", "03b52h"];
   auto fishier =3D File(fileName, "w");
   lines.map!(l =3D> l ~ '\r').each!(l =3D> fishier.write(l));
}

void main() {
   enum fileName =3D "values_test.txt";

   makeFile(fileName);

   auto lines =3D File(fileName, "r").byLineCopy(No.keepTerminator, '\r')=
;
   auto result =3D lines.joiner("-").text;
   writeln(result);
}

I would normally do the following

   auto lines =3D File(fileName, "r").byLineCopy(No.keepTerminator, '\r')=
;
   auto result =3D format!"%-(%s-%)"(lines);

But I ran into the following issue:

Ah sorry my bad. byLineCopy defaults to '\n' as line terminator 
so it worked on my system.

import std.algorithm;
File("data.txt", "r+")
     .byLineCopy(No.keepTerminator, '\r')
     .joiner(" - ")
     .writeln;

this will print the thing you wanted. If you want to capture that 
value in a variable then

auto result = File("data.txt", "r+")
                    .byLineCopy(No.keepTerminator, '\r')
                    .joiner(" - ");
