Err, ummm, ...
Are you perhaps trying to reinvent Resolver 1 -- a spreadsheet written in
Python? Maybe I misunderstand what you are trying to do, but you may want
to look at it, unless you cannot use a commercial product.

I would argue that this is a bad idea. How Python-compatible do you want
this simple Excel-like language to be? If it's really just a small subset
of the full Python language, you may be better off writing a simple parser
that emits Python text as its back end and prevents the users from doing
anyt
Yep, but all of the main IronPython nodes will show up as an extension node so
you'll want to override VisitExtension instead of VisitBinary. VisitBinary is
for simple binary operations such as adding two primitive values and doesn't
include dynamic binary operations.

Ok, I'm going to read up on this, but to confirm, I'd need something like
the following (from reading
http://stackoverflow.com/questions/7944521/interrupt-interpreted-user-code-in-silverlight
)?
public class ExpressionRewriter : ExpressionVisitor
{
protected override Expression VisitBinary(Bin
We also might recognize something like op_Power or Power if the method has
[SpecialName] attribute, but I'm not 100% certain if that's still there.

The ASTs are generally immutable so to re-write you'll create a copy of the AST
and any parent nodes. The ExpressionVisitor class makes this easy in that you
can override VisitExtension method and re-write any Python nodes you care about
there. You return a modified node somewhere within the t
It worked perfectly and fast! Thank you so much

You should be able to create a method called __pow__ like so:
public object __pow__(object b, object e) { ... }
Replace ob
Hello,
I apologize if this has been answered elsewhere, but I am unable to find
anything up to date, or that covers my question in particular.
The short version is: Can I modify the AST of a parsed file before
compiling/executing in an embedded context? I want to allow simple,
Excel-like statemen
Hey guys!
Just curious: is there a way to implement in the .NET class something that
maps to the ** operator?
I've tried the other way: calling into a Python function that works as a
factory of proxy objects. These proxies overload the arithmetic operators
and delegates everything to the real (.N
