When using readLine i get Error: Access Violation
This started with 0.89 and everything works ok in 0.88

Example code:
<CODE file="testreadLine.d">
import std.c.stdio;
import std.stream;

int main (char [] [] args )
{
 File file = new File("testreadLine.d");

 char[] line;

 do
 {
  line = file.readLine();
  printf("Line: %.*s",line);
 }while(!file.eof);
}

 getch();
 return 1;
}
</CODE>

All my code uses readLine so now nothing of that code works and i don't like having to use files from different versions!

I don't see any difference in the output. Can you post the results you get?

Line: import std.c.stdio;Line: import std.stream;Line: Line: int main()
{Line: F
ile file = new File("rt.d");Line: Line:  char[] line;Line: Line:  doLine:
{Line
:   line = file.readLine();Line:   printf("Line:
.*s",line);Line:  }while(!file
.eof);Line: Line: getch();Line: return 0;Line: }

The std.stream.readLine did change to call
 char[] readLine(char[] buffer)
which will fill the supplied buffer if the line fits so that there is less
memory allocation.

After I removed an extraneous "}" from your example, it worked fine for me on (DMD 0.89/WinXP HE). I don't know why you're getting an Access Violation. (I also added an "\n" to make the output more readable.)

import std.c.stdio;
import std.stream;

int main (char [] [] args )
{
 File file = new File("testreadLine.d");

 char[] line;

 do
 {
  line = file.readLine();
  printf("Line: %.*s\n",line);
 }while(!file.eof);


 getch();
 return 1;
}


Output...
Line: import std.c.stdio;
Line: import std.stream;
Line:
Line: int main (char [] [] args )
Line: {
Line:  File file = new File("testreadLine.d");
Line:
Line:  char[] line;
Line:
Line:  do
Line:  {
Line:   line = file.readLine();
Line:   printf("Line: %.*s\n",line);
Line:  }while(!file.eof);
Line:
Line:
Line:  getch();
Line:  return 1;
Line: }

Very strange! The difference is with the new stream.d version i don't
get any output! I get "Error: Access Violation"  the first time readLine()
is called.

I tried "printf("%.*s",file.toString());" and this prints the entire file
but
it isn't what i need. I don't know why is it working for you?

I tested four of my projects that use FIle.readLine() an none of
them work and they all crash at readLine()!

I would have also added \n if i got any output at all :)
I gues i will temporarilly have to go back to the old stream.d :(

No Access Violation here (DMD v0.89/WinXP): the only thing wrong with it is the extra '}'. Remove it and the program works fine.

F:\>dmd testreadLine
f:\dmd\bin\..\..\dm\bin\link.exe testreadLine,,,user32+kernel32/noi;

F:\>testreadLine
Line: import std.c.stdio;
Line: import std.stream;
Line:
Line: int main (char [] [] args )
Line: {
Line:  File file = new File("testreadLine.d");
Line:
Line:  char[] line;
Line:
Line:  do
Line:  {
Line:   line = file.readLine();
Line:   printf("Line: %.*s\n",line);  // added \n
Line:  }while(!file.eof);
Line: //}  <== remove this and recompile!
Line:
Line:  getch();
Line:  return 1;
Line: }

are you on Windows or Linux? I've tested on RedHat 9 and Windows XP.

Windows XP. Later i'll test it on an other computer, and let you know how
that turns out. Thanks for testing this, it seams that it only doesn't work
on
my computer.

I am very happy to say this works now in 0.90 :)
