Problem with calling ruby procs from javascript

[Aaron Renner]

I am having a problem with the following code:

ctx = V8::Context.new

ctx[:sample]=lambda {|name| "Hello #{name}"}

ctx.eval("sample('world')")

=> "Hello [object global]"

Could someone shed some light on why it's not returning "Hello world"?

Thanks,

Aaron

Yes, the first argument to your lambda is always the JavaScript `this`
object, whatever that happens to be. In this case, it is the context's
global object. What you want is:

ctx[:sample]=lambda {|this, name| "Hello #{name}"}

Looks like this could be a problem with version 0.10.1. It works correctly in 0.9.8. I'll open a bug report.

Ok, thanks. Sorry about the bug report. I didn't see your reply.
