Re: [IronPython] using XAML in IronPython

The next release of Ipy Tools (and IronPython 2.7) will greatly simplify this.  
You'll be able to call clr.LoadComponent and point at your XAML file and your 
Window subclass.  It'll then automatically add all of the x:Name (and Name'd) 
elements onto your Window subclass so you can just do "self.hello.Text" or

Don't do that, really. IronPython Studio uses IronPython 1 which is 
years out of date. Plus it is very unstable. Use IronPython Tools for 
Visual Studio 2010 instead:


http://ironpython.net/ironpython/tools/

I don't think the xaml designer works particularly well with IronPython

(Express).

Controls with an x:Name can be accessed as named attributes on parent 
controls.


Something like:

def doSomething(s, e):
button = root.hello # also equals "s" as it happens
root = XamlReader.Load(FileStream('Hello_World.xaml', FileMode.Open))
app.Run(root)

Re: [IronPython] JSON vs. IronPython

2010-07-09 Thread Tristan Zajonc

There are bugs in the IronPython 2.6.1 json implementation that I believe
have been reported and will be fixed in 2.6.2.  For instance, the following
gives me an exception:

json.loads(json.dumps(dict(test="test")))

I have had better luck with simplejson and

Unfortunately some time you want to do this - C# has "new" as well which 
explicitly lets you do this (otherwise it's only a warning).  If anything I
could see us providing a warning here but we'd need some way to squelch it 
as well.  And it would have an additional cost for constructing classes that
I'm not certain would be worth it.

I was just more wanting to see if the REPL was behaving normally...  I'm
not entirely certain what the problem is for why this won't work but I have
at least one guess.  I'll try and see if I can get a repro on my side

But the good news is I'm pretty sure the next release will fix it.  The next 
release will have Microsoft.Dynamic in the GAC and so we'll always be able
to load that assembly (right now the app domain needs to be setup correctly
and it could be there's an issue w/ the remote domain here).

Re: [IronPython] overriding methods from C# classes

2010-07-09 Thread Lukas Cenovsky


 On 9.7.2010 19:17, Dino Viehland wrote:

This is one of the reasons why I suggest WPF over WinForms.  In WPF you can
declare the event handlers in the XAML and we can wire them up to you.  In
our IronPython 2.7 source code I recently added a clr.LoadComponent method which
does this.  So for WPF the code ends up looking like:

import clr
clr.AddReference('PresentationFramework')

from System.Windows import Application, Window

class MyWindow(Window):
 def __init__(self):
 clr.LoadComponent('WpfApplication16.xaml', self)

 def Button_Click(self, sender, e):
 pass



if __name__ == '__main__':
Application().Run(MyWindow())


While the XAML looks like:

http://schemas.microsoft.com/winfx/2006/xaml/presentation";
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml";
Title="WpfApplication16" Height="300" Width="300">

 
 



And we'll both connect MyWindow.ButtonClick() to the event handlers as well as 
make Foo (the name of the button) available on the self instance.



This is very nice enhancement. Thanks.

[IronPython] reading utf-8 files

2010-07-09 Thread abdalla ramadan

Hello,

I am trying to read utf-8 files (written using notepad and have BOM) using
the following code

file = codecs.open(dir+ '\\' + i,"r",'utf_8_sig')
for line in file:
print "line"

I attached two files the a - 3 lines.txt file gives this exception and print
"line" is never called not even once

Unhandled Exception: System.Text.EncoderFallbackException: failed to decode
bytes at index 65

but the file a - 2 lines.txt is read without problems

I tried with several different texts but I could not find rule for a file
that throws this exception. I tested other files with 3 lines that did not
throw the exception.

Thanks very much for advance

yep, for the event attachement problem I think that IronPyton could have a
thin metaprogramation layer, when it encouters the  "button.Click += foo"
statement, it decorates foo automatically.
figuratively in the C# client we could have script.Execute(_scope, meta)
that raises the meta.EventAdded event that notify you the user is attaching
an event and let you decorates it. meta could also have some flags to impose
limitations etc..
 I dont know if it conflicts some core IronPython design.  I may try to do
it one day. If it works I'll propose it ;)

Re: [IronPython] Compiling so that IronPython libraries are recognized?

I found the source of the error.

C:\Documents and Settings is a protected folder in Windows 7.  You need to 
change the security permissions on it so that IronPython has permission to view 
its contents and read files from it.  First, I needed to be sure I could view 
all files and folders (one of the Options in Windows Explorer); then the 
"Documents and Settings" folder showed up.  Changing permissions can be done 
under the Security tab if you right-click on the folder and select "Properties" 
in the context menu.

Thanks to those who responded for your help and insight.

IRONPYTHONPATH is not even an environment variable.

Changing line 242 of site.py in

I can think of 1 of 2 things causing this:

1.   IRONPYTHONPATH is set somewhere and causing us to search in 
directories we shouldn't be

a.   You can just clear this env var if that's the problem

2.   There's something in site-packages which is causing this to be messed 
up.

a.   You can look in %PROGRAMFILES%\IronPython 2.6 for .NET 
4.0\Lib\site-packages and see if there's any unwanted goo here.  By default I 
think there's just a README.txt and pkg_resources.py.

b.  You can also look in %APPDATA%\Python - I think this may still not be 
properly versioned based upon Python runtime so it's possible something from 
CPython could interfere.  You could modify line 242 of site.py to be 
"IronPython" instead of "Python"


If that doesn't help it might be useful to look through that call stack and see 
where the directories are being pulled from.

I've never used JSON.NET, but the standard library json module works fine
for me.


IronPython 2.6.1 (2.6.10920.0) on .NET 4.0.30319.1
Type "help", "copyright", "credits" or "license" for more information.

[IronPython] JSON vs. IronPython


Hello everyone,

I have successfully used JSON as serialization protocol between various

In both of these cases there are no methods to be overridden.  You're just 
defining methods which you want to use for the event handlers.  You need
to connect those methods to the event handlers somewhere.  


OK hang on a second - WHICH methods do you mean precisely - In the base

Your C# code is
working probably because the connection of the event handlers is in the 
generated code in InitializeComponent().


It is there all right:

public void InitializeComponent()
{
..
this.comboBox1.SelectedIndexChanged += new 
System.EventHandler(this.comboBox1_SelectedIndexChanged);

}




This is one of the reasons why I suggest WPF over WinForms.  In WPF you can
declare the event handlers in the XAML and we can wire them up to you.  In
our IronPython 2.7 source code I recently added a clr.LoadComponent method which
does this.  


Well that certainly makes WPF worth considering. Questions:

1. when IPY 2.7 is to be released?

2. Documentation. This sort of worries me: where do I get the detailed 
info how to use this stuff? So far I have developed only in CPython/Linux...

This is one of the reasons why I suggest WPF over WinForms.  In WPF you can
declare the event handlers in the XAML and we can wire them up to you.  In
our IronPython 2.7 source code I recently added a clr.LoadComponent method which
does this.  So for WPF the code ends up looking like:

import clr
clr.AddReference('PresentationFramework')

from System.Windows import Application, Window

class MyWindow(Window):
def __init__(self):
clr.LoadComponent('WpfApplication16.xaml', self)

def Button_Click(self, sender, e):
pass



if __name__ == '__main__':
Application().Run(MyWindow())


While the XAML looks like:

http://schemas.microsoft.com/winfx/2006/xaml/presentation"; 
   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"; 
   Title="WpfApplication16" Height="300" Width="300"> 
   





And we'll both connect MyWindow.ButtonClick() to the event handlers as well as 
make Foo (the name of the button) available on the self instance.

WinForms is likely to always be a bit of a rough experience because we don't 
have the meta-data to know how to wire things up automatically for you.

Re: [IronPython] sys._getframe(0).f_lineno always returns 1

This is definitely a bug.  If you'd open a bug on CodePlex that'd be great.  
Currently we only track the line information locally but in -X:Frames mode we 
should hoist that information into the frame.

The experience here is definitely rough.  You should see the call stack in
the VS call stack window.  And it should include line number information
as well and you should be able to double click on a frame and go to the
line immediately.  But the function names are rather mangled so it doesn't
look very pretty right now.  We need to do more work to integrate w/ the
debugger beyond what we get for free from VS.

We do have an option to report inconsistent tabs/spaces...  We just need to
enable it in the parser and setup an option to disable it.  I believe it's
somewhere on the TODO list.

I set out to do just that and stumbled upon a problem:

I generated Windows form in C#, compiled into assembly (ip_cl1), copied to
python project folder:

clr.AddReference('ip_cl1')
..
from ip_cl1 import Form1


class Form1Inh(Form1):
  def __init__(self):
  Form1.__init__(self)

  def comboBox1_SelectedIndexChanged(self, sender, event):
  self.BackColor = Color.Azure

This doesn't work, i.e. method comboBox1_SelectedIndexChanged doesn't get
called. I have to expicitly add EventHandler in Python:

class Form1Inh(Form1):
  def __init__(self):
  Form1.__init__(self)
  self.box1.SelectedIndexChanged +=
EventHandler(self.comboBox1_SelectedIndexChanged);

  def comboBox1_SelectedIndexChanged(self, sender, event):
  self.BackColor = Color.Azure


Is there some way of simply overriding methods in Python so that they do get
called by form events?




In Form1.cs I have:


namespace ip_cl1
{
   public partial class Form1 : Form
   {
   public Form1()
   {
   InitializeComponent();
   }

   protected void box1_SelectedIndexChanged(object sender, EventArgs e)
   {

   }

   protected void comboBox1_SelectedIndexChanged(object sender,
EventArgs e)
   {

   }
   }
}

Re: [IronPython] Writing to a file with unicode name

2010-07-09 Thread Vernon Cole

Adballa:
  One problem you may be having is with Python trying to escape the
backslashes in your Windows file name.  I tried a very simple test using the
Python "open" statement rather than any fancy .NET things. It created a file
with a japenese name on my Windows Vista laptop. Note that I used forward
(/) slashes where Windows users would expect a back (\) slash.


out = open(u"c:/temp/青山学院大学相模原キャンパス",'w')
out.write('testing...\n')
out.close()


The same code works in CPython, too.  If I remove the "u" unicode indicator
as in
 ...open("c:/temp...
then the same code will work in IronPython and Python 3.1, since it is
unnecessary in IPy and illegal in Python 3.

Subject: Re: [IronPython] Compiling so that IronPython libraries are recognized?

There IS a working dbapi 2.0 implementation for Iron Python. see 
http://sourceforge.net/projects/adodbapi

It uses Microsoft ADO, so should be able to connect with PostgreSQL or almost 
any other tabular data source. I have not yet tested it with Postgres. That's 
the next thing on my to-do list. (I have a server running on my handy Ubuntu 
box, but can't seem to get it to connect. Why is there never enough time?)  It 
is known to work with MicroSoft SQL, ACCESS, MySQL, and IBM AS400 sql.

I also have not yet written a distutils setup for it for IronPython -- you will 
have to unzip and copy to do the install the hard way. (Another to-do list 
item.)

You will either need to find an ADO provider for Postgres, or use an ODBC 
driver and a different connection string. (I use an ODBC connection for the 
MySQL sample in the \test folder.) Let me know how it works for you.

subprocess relies on modules like signal that aren't available in IronPython

There is a partial implementation of subprocess by Jeff Hardy floating around 
that you could try. In general the IronPython support for distutils is 
"minimal", so I still wouldn't expect normal module installation to work.

I can verify that subprocess.py is in 
C:\Users\me\AppData\Local\Microsoft\VisualStudio\10.0\Extensions\Microsoft\IronPython
 Tools for Visual Studio\0.2\Lib.  Do I need to add this directory to an 
environment variable (like PATH), or is there some other way I can notify

hi Mickael

if the user write this code :

#script

def foo():
print 2/0

button.Click = foo

###

the script will execute with no exception, only when the button is clicked,
an exception is raised, how should I handle it ?

My only concern is that the users shouldn't have to think about it. Maybe I
should only let them access UI elements through non-UI proxy objects, but
it's a great limitation.

Also, anything that uses a C extension will only work with Ironclad
(http://code.google.com/p/ironclad/), and even then it might not work.
I seem to recall that there is a pure-python Postgres driver, but I
can't remember what it's called.

[IronPython] System.MissingMemberException


Hello everyone,


Ok I found the cause, the __init__ filled in from the template is 
exactly one space to the left from where it should be:


class MyForm(Form):
def __init__(self):
...
 def func(self, x):
 return x

If I shift "def __init__.." one space to the right, everything works.

But why I got such a strange exception?

And isn't there some sort of tab nanny or "inconsistent layout" exception?

[IronPython] System.MissingMemberException


Hello everyone,

I have stumbled upon what's probably an idiotic newbie problem: if I add 
any method to a class, I get System.MissingMemberException. E.g.


import clr
clr.AddReference('System.Windows.Forms')

from System.Windows.Forms import *


class MyForm(Form):
def __init__(self):
 button = Button()
 button.Text = 'Click Me'
 self.button = button
 self.Controls.Add(button)
 x = 'abc'
 b = self.func(range(5))

 def func(self, x):
 return x


form = MyForm()
Application.Run(form)


If I comment out func and reference to func in __init__, it works. 
However, with func I get lots of exceptions:

Hello,

I am trying to write to a file with the japanese name 青山学院大学相模原キャンパス
The relative path I am passing to the methods is
"output\url\c\青山学院大学相模原キャンパス"

I used two methods
s = StreamWriter(filenamenew, True, Encoding.UTF8)
and
outputfile = codecs.open(filenamenew, "w",'utf_8_sig')

which both throwed the following exception:
Unhandled Exception: System.ArgumentException: Illegal characters in path.
