Re: [IronPython] Need a Good Embedded Example

2007-10-19 Thread Joshua J. Pearce

What am I doing wrong? I have a form with two text boxes and a button. When
I type, "tb.clear()" into the first textbox and click the button, I get the
a MissingMemberException which states, "'TextBox' object has no attribute
'clear'".


public partial class Form1 : Form
{
public static PythonEngine pe = PythonEngine.CurrentEngine;
public Form1()
{
InitializeComponent();

ScriptDomainManager.CurrentManager.Host.DefaultModule.SetVariable("tb",
textBox2);
}


private void button1_Click(object sender, EventArgs e)
{
pe.ExecuteCommand(textBox1.Text);

}
}


Thanks,

Josh Pearce

I am very sorry! I just noticed this:

ScriptDomainManager.CurrentMan
ager.Host.DefaultModule.SetVariable("SomeName",
SomeObject);

SomeObject is then available to user code as SomeName...

That is exactly what I want to do!!!

Thank you very much!

You never mentioned you were using ASP.NET. You have mentioned C#.

Can you clarify what you mean by this line for me?  Can you provide a
C# method  that exists in the same scope as an IPY engine?

There must be a custom interface, how would an outside script know
about a custom method outside it's scope without an custom interface?
Michael and myself have both provided examples.

If you have a C# method it must be represented by something else in
the script or python code that IronPythonEngine is using, then update
the script or python code loaded in the IronPythonEngine using the
examples provided.

Since I have not seen your source, I don't know why you believe
importing the AppService dll and create your own instance in the IP
engine will be too much overhead.  That sounds like the bet way to go
but I am not familiar with your source.
Good Luck!

Re: [IronPython] Need a Good Embedded Example

2007-10-18 Thread Joshua J. Pearce

My application is ASP.NET, I hardly think integrating CPython is going to be
a better choice.

I really hope I can be clear this time and not encourage suggestions to do
all kinds of other stuff that what I am asking about, so here it goes:

Is is possible to 'expose' c# methods that exist in the same scope as an IPY
engine, to that engine so that an arbitrary one of those methods might be
called by python code code that that engine executes?

Thanks,

Personally, I would just use Python as the scripting for a number of reasons.
1) IronPython is a .Net library not a language
2) IronPython supports Python language modules (to a certain point)
3) Possibly provides compatibility to CPython and IronPython

I believe this would be a better design for your application and be
better in the long run, esp. as IronPython grows and changes rapidly.
This is mainly why I designed pswrdgen and pswrdgeniron this way.
However, just my two cents and not fully aware of your apps specific details.

 You should be able to place objects into the 'user scope' using the 
same SetVariable technique. That way the user can call methods on these 
objects from their code.

ScriptDomainManager.CurrentManager.Host.DefaultModule.SetVariable("SomeName",
SomeObject);

SomeObject is then available to user code as SomeName...

I don't see why you would want to if you are using an IronPythonEngine

Just do...
 //Call your Service method and assign return value to a global
 COUNT = myAppService.getcount("my arg1");

I still don't see why you would need it in the script if you are using C#.

Joesox,

Thank you very much! Now, what if I the getcount() method was actually
getcount(string arg1), is there a way to call it from within the IP script?
Or do I need to parse the IP script ahead of time, and call the function
myself? That would be like writing my own scripting language, so I hope
there is a way to call the method from within IP scripts.

What are the return values of myAppService.ServiceMethod()?
Depending upon these values, you will need to handle them before
sending them to the pe.

So it sounds like you need something like:

public int COUNT;

private void MyIPGetCount()
{
  //Call your Service method and assign return value to a global
  COUNT = myAppService.getcount();

  //Create variable bridge from C# to IronPython engine
  //I like to pretend I am just using a IP command line to help
figure out what I need to do
  pe.ExecuteCommand("PyCount = 0");

  //Set the IronPython bridge variables...
  
ScriptDomainManager.CurrentManager.Host.DefaultModule.SetVariable("PyCount",
COUNT);
pe.ExecuteCommand("PyCountTwo = PyCount");
}

This is a simplified version of what I am guess what you need to do
but there you go.

2007-10-18 Thread Michael Foord

Hello Joshua,

I'll take a look at this.

It is really easy for IronPython 1 and everything has changed for IP 2 
(and the docs are not exactly complete).

It just takes a bit of exploration. You need to be able to set some 
globals in the default module (where you can make your .NET objects 
available to IP code - and then pull the globals back out after 
executing the Python).

[IronPython] Need a Good Embedded Example

2007-10-17 Thread Joshua J. Pearce

I am looking for an embedded IronPython 2.0 example beyond the simple hello
world one I quoted before.

What I want to know is:

1) How to get variable output from the script back to my c# code.

2) How to call scripts with multiple statements.

3) Do all variables need to be set on the script object, or can their
declaration just be part of the script code?

4) Is there a good and simple example anywhere that shows how to host the
IronPython engine in a c# app and let users manipulate your program objects
via ipy scripts?

5) How can I expose c# methods to as IPY functions?

Re: [IronPython] Need a Good Embedded Example

2007-10-16 Thread Dino Viehland

Yep, we've temporarily ripped out all pre-compilation support from v2.0 to make 
the refactoring work easier so pyc definitely won't work there (and there's 
really no way to make it work there w/o a rather large amount of work).

Hi Dino,

Is this why I am having trouble with the pyc.py sample? It does say
1.01 in the description so maybe I should expect issues :-)

Traceback (most recent call last):
  File pyc.py, line 35, in Initialize
  File , line 0, in _stub_##227
AttributeError: 'NamespaceTracker' object has no attribute 'CompilerSink'

Thanks,
Davy

Re: [IronPython] Need a Good Embedded Example

2007-10-16 Thread Dino Viehland

Are you looking for samples in v1.0 or v2.0?  The code you quoted below is some 
version of v2.0 (we're still working on the final tweaks to what will become 
the new, final, hosting model).

Subject: [IronPython] Need a Good Embedded Example

I have been looking for a good example of embedding IronPython in a c# 
application. I am under the impression that there have been some major changes 
in the way this is done from version 1.1 to 2.0.

This is what I found at the Python Cookbook site:

namespace IronPythonScriptHost
{
class Program
{
static void Main(string[] args)
{
string code = "print \"Hello \" + Name";
Script.SetVariable ("Name", "Me");
Script.Execute("py", code);
}
}
}

That's nice, but doesn't really help me to know how to get variable output from 
the script back to my c# code. I also need to know how to call scripts with 
multiple statements and whether all variables need to be set on the script 
object, or can their declaration just be part of the script code.

Is there a good and simple example anywhere that shows how to host the 
IronPython engine in a c# app and let users manipulate your program objects via 
ipy scripts?

Thanks!

I have been looking for a good example of embedding IronPython in a c#
