Hello,

i try to get the process id with Regan's programm
process.d and pipestream.d under linux dmd 154 .

mport lib.process;
import std.stdio;
import std.string;

void main()
{
Process proc;
proc = new Process("echo $$");
writef(proc.readLine());
}
// dmd pro.d lib/process.d lib/pipestream.d 

I get 92 error massage.
Here are the first one:

dmd pro.d lib/process.d lib/pipestream.d
pro.d(9): class lib.process.Process member readLine is not accessible
lib/process.d(335): declaration lib.process.Process.splitArgs.delims is already

and so on.

Maybe someone have an example that run under linux.

That's because it was never compiled/tested on linux :)
I have done so now, attached is a fixed version.

I sit behind a firewall, so i can't download the file from the
web site.
I try it again on friday from home with pan.

Hello,

i have successfully compile my program, but i get no 
response.


import lib.process;
import lib.pipestream;
import std.stdio;
import std.string;

void main()
{
auto Process p = new Process("ls -la");
writefln("%s",p.readLine());
}
// dmd ping.d lib/process.d lib/pipestream.d
build ping

gcc lib/process.o ping.o lib/pipestream.o -o ping -m32 -lphobos -lpthread -lm


I have comment in the line 230 in process.d
extern (C) char* strerror(int);
and the line 50 in pipestream.d 
char* strerror(int);

 process.d and pipestream.d under linux dmd 154 .

Why not just call "getpid"?

import std.c.process;
import std.stdio;

void main()
{
	writefln(getpid());
}

 import lib.process;
 import std.stdio;
 import std.string;

 void main()
 {
 Process proc;
 proc = new Process("echo $$");
 writef(proc.readLine());
 }
 // dmd pro.d lib/process.d lib/pipestream.d

 I get 92 error massage.

That's because it was never compiled/tested on linux :)
I have done so now, attached is a fixed version.

Regan

The problem is that "ls" does not exist in the current directory. You need  
to include the full path to the binary, eg.
   auto Process p = new Process("/bin/ls -la");

fork/execve doesn't work like the bash shell, it won't scan the PATH for  
the command it's given, it just runs exactly what you ask it to.

I need to look into what I can do in the event of a failure to notify the  
parent thread (cos once you call fork() you get a copy, that copy calls  
execve and should never return, it does, indicating a failure).

 writefln("%s",p.readLine());
 }
 // dmd ping.d lib/process.d lib/pipestream.d
 build ping

 gcc lib/process.o ping.o lib/pipestream.o -o ping -m32 -lphobos  
 -lpthread -lm


 I have comment in the line 230 in process.d
 extern (C) char* strerror(int);
 and the line 50 in pipestream.d
 char* strerror(int);

Yep, those are declared in std.string and we don't need to declare them  
anymore.

Oh, what a silly mistake from me.
The "ls -la" and "ping" example run well, only the
"echo $$" print $$ instaed of the process id, but it's not so
importent, i get your example with getpid.

Thank you.

fork/execve doesn't work like the bash shell, it won't scan the PATH for  
the command it's given, it just runs exactly what you ask it to.

I need to look into what I can do in the event of a failure to notify the  
parent thread (cos once you call fork() you get a copy, that copy calls  
execve and should never return, it does, indicating a failure).

 writefln("%s",p.readLine());
 }
 // dmd ping.d lib/process.d lib/pipestream.d
 build ping

 gcc lib/process.o ping.o lib/pipestream.o -o ping -m32 -lphobos  
 -lpthread -lm


 I have comment in the line 230 in process.d
 extern (C) char* strerror(int);
 and the line 50 in pipestream.d
 char* strerror(int);

Yep, those are declared in std.string and we don't need to declare them  
anymore.

 Oh, what a silly mistake from me.
 The "ls -la" and "ping" example run well, only the
 "echo $$" print $$ instaed of the process id, but it's not so
 importent, i get your example with getpid.
 
 Thank you.
 
 

as with "ls" vs. "/bin/ls" meta string explantion is done by the shell.
