Re: Vibe.d: Listening to port 8080 on external device doesn't work

Object.factory from shared libraries
I'd like to extend my program's functionality from plugins, that'd be loaded by name (or not) as requested by the config file. Is it possible to throw in a few dlls/sos implementing those new modules into a directory and hope that they will be all loaded and available to Object.factory in the main executable? I hope I'm clear enough.

I hope I'm clear enough. If you either enumerate all dynamic libraries in a directory, or a list from a config file, then use dlopen on all libraries. Then I think Object.factory should work. But dynamic libraries are basically only working on Linux. That would be satisfactory to me, except for the linux-only part. In that case, I think I'll simply try to call filename() as the factory function in each library - that should work everywhere, right?

The following worked:
import std.stdio;

import std.exception;
import std.string;
import std.algorithm;
struct Data
{
int i;
string s;
}
Data toData(char[] line)
{
int i;
string s;
auto slice = line;
const items = formattedRead(line, %s %s, i, s);
enforce (items == 2, format(Incomplete line: %s, slice));
return Data(i, s);
}
void main()
{
auto data = stdin.byLine.map!toData;
writeln(data);
}
I could not get it work with fill because fill requires
specific types of ranges, which neither the destination nor the
source were. For example, I wanted to use std.array.Appender
but fill wants an InputRange. Also, the source is not a
ForwardRange because it is consuming from stdin.
However, it is easy to make an array with std.array.array:
import std.array;
writeln(data.array);

Thank you for your reply.
That's not what I wanted. Maybe I should explain instead of
expecting you to divine my intentions, though :) I am trying to
rewrite the following program in D--making it more elegant:
http://melpon.org/wandbox/permlink/ff42FoyKgqJK60sm
As you can see, I can have one input line consisting of n words
and then n integers and I can read from it easily. My question
whether stdin.byLine allows me to do this remains unanswered (or
I failed to understand the answer), although I am not hopeful.
As to std.fill: I find myself surprised. Any idea why the input
range is considered incorrect? In any case, should
integers[0..$].fill(...) not make it correct, at least in regards
to the first argument? Docs have an example with int[]
I expected my D code to look more or less like the following:
words.fill(stdin.by!string);
integers.fill(stdin.by!int);
zip(integers,words).map!(p = p[1][p[0]]).join.writeln;

My question whether stdin.byLine allows me to do this remains unanswered (or I failed to understand the answer), although I am not hopeful. You should be able to use `std.algorithm.take` to read exactly 5 integers. However, in order to read up to the first empty line, for example, the input would have to be a forward range (= rewindable), which stdin.byLine of course is not. Maybe you could constructor a wrapper range that caches input lines as necessary. Okay, I think I'll simply skip this for now. I hoped that there would be a way of reading stdin composable with std.algorithms, as is the case in C++. I guess this works for now http://dpaste.dzfl.pl/6801615160e3 I have a follow-up question: why does zip not accept an array?
input range from stdin
I'd like to have something similar to C++'s std::istream_iteratorint(std::cin) Is it possible? I'm relatively indifferent to efficiency of the solution.

How to set workDir for std.process.execute ?
Hello,
I'm trying to follow the documentation:
http://dlang.org/phobos/std_process.html#.execute
Unfortunately, the following code gives me a compiler error:
class Probator
{
char[] dir;
this(const char[] dir){
this.dir = dir.dup;
}
int revision(){
import std.process;
import std.conv;
const char[] workDir = ~.dup;
auto p = std.process.execute([svnversion, dir], null,
Config.none, size_t.max, workDir);
if(p.status == 0){
return to!int(p.output);
}else{
throw new Exception(p.output);
}
}
}
error:
/d629/f876.d(15): Error: function std.process.execute
(const(char[][]) args, const(immutable(char)[][string]) env =
null, Config config = cast(Config)0, ulong maxOutput =
18446744073709551615LU) is not callable using argument types
(const(char)[][], typeof(null), Config, ulong, const(char[]))
It's as if the implementation didn't expect the last argument.
