module std.regex

2013-12-30 Thread Benji 

Hello,
when I try to run following code:

import std.stdio;
import std.net.curl;

void main()
{
writeln(dlang.org);
}

I get following error:

Fatal Error while loading 
'/usr/lib/x86_64-linux-gnu/libphobos2.so.0.64':

The module 'std.regex' is already defined in './maina'.
Segmentation fault (core dumped)

Somewhere I read that this should fix it:
- Make ModuleInfos immutable, which is something we should do 
anyhow.


But what are ModuleInfos ? Where I can find them and what 
exactly to do with them?

Which compiler/version?

It's a bug in 2.064-2 when using shared library. You as end 
user can't do much about it - wait for the next release where 
it should be fixed or use static linking for the moment.

This is part of core developers discussion and isn't something 
easily tweaked (else it would've been already fixed).


Thanks! Could be downgrading to 2.063 the solution?

std.net.curl - get() is too slow

2013-12-20 Thread Benji 

When I call get() function from std.net.curl,
I notice it's extremely slow!
Maybe 50 times slower than in Python..

Is there any better/faster alternative?

So format c: it is ...
If you are switching already, Gentoo 
(http://www.gentoo.org/main/en/about.xml)
is also a viable option for D development 
(https://github.com/gentoo-dlang)

especially if you want to try alternative compilers to DMD and
plan to use libraries like GtkD and want them to work on top
of all your installed D compilers.
[Currently all D compilers produce libraries that are
incompatible with those of the other compilers, so a library
needs to be compiled and installed up to 6 times for all three
compilers and 32/64 bit versions. So it is nice to get some
assistance from the package manager here.]


I have Debian now,
and it works with dmd ~/main.d -L-lcurl :)

eclipse - adding custom flags to dmd when compiling

2013-12-15 Thread Benji 

I want to compile file 'main.d' within Eclipse by following way:
  dmd ~/main.d -L-lcurl

How to achieve that?
By default, Eclipse compiles it without -L-lcurl flag.

 How to 'update druntime' ?

 how did you install dmd/druntime/phobos originally?

As it is mentioned in installation instructions to the dmd 
(linux-ubuntu)


Did you use the .deb file? It shouldn't produce such a
version mismatch. Did you install over a previous installation
and possibly have some leftover files from the old DMD version?

I'd say format c: and start over with the installation of DMD.
In any case, if you didn't install from the GitHub sources
this error message should not appear and someone who isn't
hacking on DMD does not have to update druntime manually.


Yes, I used :(

I tryied it again via zip-archive, and it works...
but, using std.net.curl module functions doesn't work for me...

This is my error: (after get(google.com) call)

And when you compile like this?: dmd helloa.d -L-lcurl
This will link in the static version of Phobos and there is
only one static (.a) Phobos on any system. -L-lphobos2 might
link against the wrong (.so) if you have an old version. I'm
just guessing here.

stdout - autoflushing

2013-12-03 Thread Benji 

Hello,
in order to have correctly displayed output (before reading 
something from stdin),

I must call stdout.flush().
Sometimes, it's really annoying, especially when it is necessarry 
to call it 10 times.


For example:
write(Enter some string: );
stdout.flush();
string a = readln();
write(And again please: );
stdout.flush();
string b = readln();
...

Is there any way to prevent this?

What about:

void prompt(A...)(string fmt, A args)
{
writef(fmt, args);
stdout.flush();
return readln();
}

auto a = prompt(Enter your name: );
auto b = prompt(Enter your age: ).to!int;
... // etc.

I am surprised that you need that. What is your platform?

Normally, stdin and stdout are tied. Reading from stdin 
flushes stdout automatically.
