Hi,
does anybody know how to bring std.conv.to or something similar to
output into an output range?
int a = 42;
char[25] buffer;
to!typeof(buffer[])(a, buffer[]);
I want to send these texts throw sockets. Therefore I'd like to reuse
the buffer.

You could use std.format.formattedWrite.
import std.exception, std.format, std.stdio;
// I don't know if this already exists somewhere:
struct Filler(T:T[]){
this(T[] pl){payload = pl;}
size_t index=0;
T[] payload;
void put(const T[] s){
enforce(payload.length>=index+s.length);
payload[index..index+s.length]=s;
index+=s.length;
}
void put(char s){
Should be 'void put(T s)'.
Just noticed that this overload is not even necessary.
enforce(payload.length>=index);
payload[index++]=s;
}
@property auto data(){return payload[0..index];}
}
auto filler(T)(T pl){return Filler!T(pl);}
void main(){
int a = 42;
char[25] buffer;
auto f = filler(buffer[]);
formattedWrite(&f,"%s",a);
writeln(f.data);
}
