Type Conversion in v8onpython
Quick v8onpytyhon update Numeric and boolean values are returned as native Python objects now (thanks, Seo!). Anything that is undefined is converted to the Python NoneType:
>>> js_code = "1+2"
>>> v.compile(js_code)
3.0
>>> v.compile('1 < 2')
True
# the following has type NoneType
>>> v.compile("function f(){}")
>>>
Everything else is still...
Borges on forgiveness
From Borges, two dual views on forgiveness. One from the point of the aggressor, the other one from the point of the victim (In “Legend”):
“Now I know that you have truly forgiven me,” Cain said, “because forgetting is forgiving . I, too, will try to forget.”
“Yes,” Abel said slowly. “So long as remorse lasts, guilt lasts.”
But...

Last week I got distracted hacking out a REPL for v8onpython, with colors, tab completion on Number, String,Date,Object objects, reverse search via Ctrl+R. It’s basically functional at this point although something that’s sorely missing is multi-line editing.

Experimental Javascript console on v8onpython
The really exciting thing is that we have preliminary tab completion support (only for the Number type) for v8onpython!

v8onpython news
One feature/bug of the current state of v8onpython is that we are using the same context to execute our scripts:
>>> import v8onpython
>>> v = v8onpython.Script()
>>> v.compile('function f(a,b){return a}')
'undefined'
>>> v.compile('f(-3,5)')
'-3'
This almost feels like a javascript REPL, although it’s less sophisticated then the current one in...

Simulating the c++ -> operator in pyrex/cython
Recently, I stumbled into a piece of c++ code that I was trying to transform into Pyrex that looked like this:
ObjectA a = new ObjectA();
ObjectB b = a->Print();
Now a did not have Print() as one of its member functions. How would I emulate -> in Pyrex? Recall that in C and C++, one defines the p->member operator as (*p).member, if p is a pointer. Here’s what I did:
I defined...

Exceptions on v8onpython
Now horrible things won’t happen if you pass invalid JavaScript to v8onpython:
>>> import v8onpython
>>> v = v8onpython.Script()
>>> v.compile("function A(){return 1;} A();")
'1'
>>> v.compile("1.32w")
>>> 'SyntaxError: Unexpected token ILLEGAL'

V8onPython
I’ve written a small module called v8onpython. It runs Javascript code go Google’s V8 engine.
The module takes any valid Javascript string, compiles it, runs and returns the result of the of the command as a (Python) string object. Think of this as eval() in Python. This is released under the BSD license.
Example usage:
>>> import v8onpython
>>> v =...
