Prototypes export/import

Konstantin Tcholokachvili — 2013-03-23T11:15:49

Hello,

I get back to neko and I would like to know how prototypes export system
works.
For example, I createed a file called proto.neko with the following
contents:

-------------------------------------------------------------------------
var proto = $new(null);
proto.foo = function() { $print(this.msg) }
-------------------------------------------------------------------------

then a file called lod.neko with the following contents:

-------------------------------------------------------------------------
var proto = $loader.loadmodule("proto",$loader);

var o = $new(null);
o.msg = "hello";
$objsetproto(o,proto);
o.foo(); // print "hello"
-------------------------------------------------------------------------

But when I do:
nekoc proto.neko
nekoc lod.neko
neko lod.n

I have the following message:

Called from lod.neko line 6
Uncaught exception - Invalid call

Line 6 corresponds to the "o.foo()" so it seems that the prototype isn't
fully imported.

What happens?


Thank you in advance.

nekoc -doc and nekoc -link

I see that neko 2.00 for linux has been released. Congratulations  and
thank you!

I would like to know  about two options in the compiler nekoc:

First, the doc option. Looking in source code looks like it search text
between <doc> and </doc>, can you give an example of how document a
function, please?

Second, the linker option. how can I use it?

Thank you

Read user input

Fernando Raya — 2013-02-12T12:25:52

How can I read user input in Neko?

Something like:

     $print("Give a number");
     var input = read-line();
     $print("Your number was ", input);

Thanks

Writting native code

Lars Madson — 2013-02-10T17:37:34

Hi,

I'm doing some bash script to add linux users, delete and upate, also for
htpasswd and mysql.
So I could call them from some haxe/Neko web interface.

Would it be of any interest to make a Neko primitive for those ?

Thanks

apache error load mod_neko2.ndll,undefined symbol ap_log_error

Lars Madson — 2013-01-24T12:20:46

Hi,

I updated Xampp on archlinux. Since then I can't start apache anymore.
I looked on how to fix this from apache then but can't find a solution,
like maybe a way to bypass this check for the missing symbol. Or maybe a
library I should install.

I recompiled neko 1.8.2 but this undefined symbol seems the normal behavior.

Any idea what I should do to fix this ?

thanks
Laurent

Compiling trunk on Windows/MSVC

Jonas Malaco Filho — 2013-01-15T02:17:23

Hi there...

I've been trying to compile neko, nekoc, nekoml and associated libs on
Windows/MSVC. Amost everything is working, although I didn't try to compile
mod_tora and mod_neko. However, I couldn't quite figure out what is the
workflow used by Nicolas... What is the easiest way to compile on MSVC?

I also haven't been able to figure out where does os.ndll comes from and
how to compile nekoml.std. I tried running the command in
src/tools/install.neko, but got the follwing error:
Core\Core.nml(201): Cannot unify error and Core\Core.error

Can you provide some help?

NekoVM size claim

Paul Sokolovsky — 2013-01-11T13:18:40

Hello,

I should start with saying that I'm absolutely amazed by Neko/Haxe -
it's marvelous that in the world trapped in JavaScript mediocrity some
people where brave enough to build complete ecosystem which is both
real-world and based on solid foundations of Lisp and *ML heritage.

Well, people can never get enough, and my question is in that vein. One
of the first things I read about NekoVM was FAQ which is at
http://nekovm.org/faq?s=68#how_is_neko_different_from_llvm_or_c claims
that libneko.so is 68KB. That's not what I see with the latest version:

$ ls -l /usr/lib/libneko.so.0.2 
-rw-r--r-- 1 root root 120992 Apr 27  2012 /usr/lib/libneko.so.0.2

Building it myself (all happens on x86), I got the similar results.

So, on what the information quoted above is based, and is it possible
to cut down the size after all?

It's not idle question - I would never consider giving up Python, if
didn't get a project to put a webapp on an Embedded Linux system with
4Mb flash, with 300Kb space normally free, most of

Strange behaviour when multiplying by -1

Konstantin Tcholokachvili — 2012-10-20T17:19:00

Hello,

I'm implementing a tool which trans-compiles (yet not complete) Python into
neko.
I implemented the abs() built-in function in Python, it's supposed to give
the absolute value of a number, for example abs(-30) must give back 30.

So I've done:

var abs = function(n)
{
if (n < 0)
{
return n * -1;
}
return n;
}

$print(abs(-30)+"\n");

But it gives me back -1.

I wonder if there is a bug in NekoVM because in Python an equivalent
function gives me a correct answer.

def absolute(n):
...     if n < 0:
...         return n * -1
...     return n
...
30

Can someone tell me what really happens?

For the sake of curiosity the project is at:
https://github.com/narke/py2neko


Thanks in advance,

Konstantin Tcholokachvili

Does the GC really matters?

Konstantin Tcholokachvili — 2012-07-13T15:19:32

Hello,

I'm planning to write a hobby OS.
I already hacked a little kernel which needs to be rewritten.

The idea is to be able to write most parts in my preferred languages such
as Python and Mythryl.
The core (memory allocation, etc) will be in C and asm.

I started Python to neko and Mythryl to neko projects but they aren't yet
complete.

So, NekoVM is the cooler VM I found, I plan to integrate it in the kernel
level, but one thing makes me wonder: is the use of GC really mandatory? Or
this is just to avoid memory allocation related errors?

Because instead to port NekoVM + GC, for me it would be much easier to make
a neko compatible interpreter, say in flex & bison.
Thus reducing the size of the binary.

As you are experienced with NekoVM, what's your opinion?

Best regards,

Konstantin Tcholokachvili

Neko server and mod_neko issues on OS X 10.6

neko on Archlinux ARMv5

Alexander Syed — 2012-05-03T16:35:24

Hi all,
I'm new to the mailing list and also new to Neko.
I wanted to get Neko running on a Pogoplug (ARMv5) so that I could run 
some Haxe code on it.

I have outlined how I got it working here...

Trouble installing mod_neko on Mac

Nico Zimmermann — 2012-03-18T18:17:14

Hi everyone,

I am trying to install mod_neko on Apache2 on my Mac (10.7.3) by adding:

LoadModule neko_module /usr/lib/neko/mod_neko2.ndll

<IfModule mod_neko.c>
        AddHandler neko-handler .n
        DirectoryIndex index.n
</IfModule>

However, when I restart the server I receive the following error message:

"Syntax error on line 31 of /Applications/MAMP/conf/apache/httpd.conf: Cannot load /usr/lib/neko/mod_neko2.ndll into server: dlopen(/usr/lib/neko/mod_neko2.ndll, 10): no suitable image found.  Did find:\n\t/usr/lib/neko/mod_neko2.ndll: mach-o, but wrong architecture"

Any ideas?

Greetings, Nico.

Builtin not found

Alexander Konotop — 2012-03-05T15:39:37

Hello :-)

I'm building 64bit neko 1.8.2 *.deb package.
I've built it, helloworld (trace) works. Also I've built haxe 2.08.
But when I'm trying to compile more smth more complex than helloworld -
I get this message while trying to run compiled *.n:

Uncaught exception - module.c(124) : Builtin not found : t

What does it look like, what does it mean? I can't load ndlls? I've put
them in the wrong place? I have them in /usr/lib/neko. Maybe I've
missed some compilation flags? I had an issue with libneko.so - for
example nekotools server crashed while trying to start. I've created a
symlink /usr/lib/neko/libneko.so -> /usr/lib/libneko.so - now nekotools
server works. But my application still does not. BTW application uses
haxe.Http and neko.vm.Threads.

ThreadRemotingServer dialoging with a php server

Thomas Fétiveau — 2012-01-09T19:17:41

Hi,

I'm having a problem with a neko.net.ThreadRemotingServer opening from 
time to time HttpConnections to make some calls on a remote PHP server.

The issue is that, for some of these calls, the PHP server needs to 
connect though a php_net_Socket to the ThreadRemotingServer within the 
processing of a http request from the ThreadRemotingServer (ouch :)!).

The problem is that when it tries to do so, the connections from the PHP 
server to the neko server aren't opened until the initial http 
connection from the neko server to the PHP one is closed. And the 
initial http request from neko to the PHP server won't be responded 
until the PHP server can process completely the request (and thus make 
these calls to the neko server). What I get is that the http connection 
from the neko server times out as the connections from the PHP server to 
the neko server can't be opened.

Well, I hope I was clear enough :)... The workarounds I've found are :

  - on the neko side, to open the http connections and make t

Hi,

I would like to know how to take thread dumps on the nekoVM (I'm running

Is there any web page summing up all diagnosis and troubleshooting
