[IronPython] SilverShell 0.6.1 Released - many "intellisense" fixes + all source
I'm trying to walk a fine line between spamming this list, and alerting the 200+ people who downloaded SilverShell 0.6.0 that there's an important new bugfix release. I put a lot of irritating flaws in the "intellisense" to rest, including a major issue with member completion that crept into 0.6.0 at the last minute. Had I known there was going to be such a response I think I would have tested it more thoroughly. As promised all source code is in this release. Please notify me of remaining bugs, either via email, or via the issue tracker on Google Code. Patches are most welcome. Thanks for downloading SilverShell! -Dan ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com

>>>Did you have a chance to do that?
Not in terms of a blog post...
But this example should demonstrate that
public void InvokeInstance_Example() {
ScriptEngine engine = _runtime.GetEngine("py");
ScriptScope scope = engine.CreateScope();
ObjectOperations operation = engine.CreateOperations(scope);
string pyCode = @"class Foo(object):
i = -1
def Bar(self):
return i";
ScriptSource src = engine.CreateScriptSourceFromString(pyCode,
SourceCodeKind.Statements);
src.Execute(scope);
object FooClass = scope.GetVariable("Foo");
object newObjectInstance =
engine.Operations.CreateInstance(FooClass, new object[] { }); // create new
FooClass
var bar = engine.Operations.GetMember>(newObjectInstance,
"Bar");
int n = bar();
Assert.AreEqual(-1, n);
}

Sesh, after your changes (below), and replacing using System.Scripting
with using Microsoft.Scripting
it works!
This is great. Thank you.
You mentioned that planned to post some code showing how to call python
class instance methods. Did you have a chance to do that?
Thanks again!

Re: [IronPython] SourceCodeKind.Statements versus SourceCodeKind.InteractiveCode
This behavior is actually defined by CPython which specs interactive input as being: interactive_input ::= [stmt_list] NEWLINE | compound_stmt NEWLINE The stmt_list allows the semi-colon delinated lines and the compound_stmt allows a single statement. The idea here is that this is for a console input and that there really should be only one statement being entered at a time. We could de-couple the relationship between interactive code & printing expression statements though. Internally they're not really that related so it wouldn't be that hard to do. If that sounds like it'd help you (or if there's others that would like to see it) you could open a feature request on CodePlex. > -Original Message- > From: [EMAIL PROTECTED] [mailto:users- > [EMAIL PROTECTED] On Behalf Of Jeff Slutter > Sent: Saturday, December 06, 2008 3:33 PM > To: Discussion of IronPython > Subject: [IronPython] SourceCodeKind.Statements versus > SourceCodeKind.InteractiveCode > > I'm working on getting an interactive script console into my > application.

[IronPython] SourceCodeKind.Statements versus SourceCodeKind.InteractiveCode
I'm working on getting an interactive script console into my application. Information on how to do this is a bit hard to find but I came across an app.py by Jim Hugunin showing how to do it with Silverlight. I based my C# app around that and have something working pretty well. I'm always using SourceCodeKind.InteractiveCode when compiling the source snippets and it works great. But there is a situation where it doesn't do what I expect. If I pass in the following string: a = 10 + 3; print(a); (note: two statements, separated with a newline) It will give me an error saying that the 'print' is an unexpected token. If I pass in the following string: a = 10 + 3; print(a); It works as expected (printing out 13). It works fine if there are multiple lines for a statement like: if( a > 10 ): print(a); If I use SourceCodeKind.Statements then all of the above works just fine, but I don't get the nice things like the automatic print of the returned value of the statement or the "_" variable. Is there a reason why InteractiveCode does things different like that? I want to give a consistent interface to my users and I think they would expect that they can give two statements at once (especially if they can do it on the same line). I can work around this to get what I want by building up my buffer one line at a time and testing to see if it is a "complete" statement and executing that, then continuing to feed in the next line, etc. But, if I don't have to, I don't want to do that. Any ideas? Thanks Jeff ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com

Re: [IronPython] CP #20099: Stack Overflow using super() in dict subclass
The immediate question would be does fixing this unblock all other Django issues? If there's going to be a long tail of other bugs then it'd be better to just fix them all for 2.0.1. If you want to try this out the fix is easy, in PythonDictionary.cs replace the line: this[(object)null] = value; with: _storage.Add(null, value); You'll probably find that alone isn't sufficient - the getter probably needs a similar change where it does the same thing as this[object key]. > -Original Message- > From: [EMAIL PROTECTED] [mailto:users- > [EMAIL PROTECTED] On Behalf Of Jeff Hardy > Sent: Saturday, December 06, 2008 12:57 PM > To: Discussion of IronPython > Subject: [IronPython] CP #20099: Stack Overflow using super() in dict > subclass > > Hi, > Django's MultiValueDict is a key piece of its URL routing, and it > appears to be broken on IronPython 2.0RC2 (and RC1) when using a key > of None.
