Thanks a lot.
Weird. It is not in the library reference in http://www.d-programming-

throught the previous one was the official web site now. It seems it
still is not synced well.
import std.process;
void main() {
execvp("ip", ["route"]);
}
result:
Object "ute" is unknown, try "ip help".
So the first two bytes are lost.
After adding two spaces in the first argument, it works.
import std.process;
void main() {
execvp("ip", [" route"]);
}
dmd 2.055 linux 32bit.
Is
#import std.process
void main() {
execvp("ip", "route");
}
result:
Object "ute" is unknown, try "ip help".
That is the first two bytes are lost
Adding two spaces works:
#import std.process
void main() {
execvp("ip", " route");
}
Version 2.055, linux, 32bit
Thanks.

In D2, how can we get the output of running a script.
We can use 'system' to run the script, but how we cannot assign the
standard output of the running script. Is there any way to do it, or
whether it will be included into future version of std.process? Thanks a
lot.

Yeah that was already planned, no worries. :)
I'd suggest having a version(warnings_suck) { static assert(0); }
so people who want more info can just stick a -version= on the build
and get the compiler's help.
static assert(0) gives a kind of compile time stack trace.

Ah, you're right. It should have been a compile-time argument, conv.to
actually works in CTFE:

struct Bar { }
struct Foo
{
this(int line = __LINE__)(Bar bar)
{
pragma(msg, "Warning: Constructing Foo with Bar incurs
precision loss. Line: " ~ to!string(line));

One other thing, count can only take an array which seems too
restrictive since walkLength can take any range at all. So maybe count
should be just an alias to walkLength or it should possibly be removed
(I'm against fully removing it because I already use it in code and I
think the name does make

Don't use length, use std.utf.count, ala:
