I am using eval to dynamically define a method, and at some point, I want to
do this:
raise "Invalid type: #{val}“
Except that this is inside an eval’d string, and so #{val} gets evaluated the
first time, and at this point val doesn’t exist. I’ve tried all sorts of
things like
raise “Invalid type: #{”#{val}”}"
but none of them quite do what I want. I eventually settled for
raise "Invalid type: " + val.to_s
but it still raises the question, how do you force a #{…} not to be
evaluated?

It’s so obvious, it’s easy to miss:
eval %{
def greet name
puts “Hello, #{name}”
end
}
Ah, beautiful. I don’t think I tried this, because Vim still highlights the
#{…} as if the \ wasn’t there, and I tend to trust Vim’s highlighting more
than myself when it comes to syntax. Can whoever’s in charge of the standard
Vim syntax highlighting file fix this please? Assuming they read -talk…

I would strongly recommend that you reconsider your position.

Thanks, I’ll fix it.

Doug,
Have you thought of keeping this in
the RAA?
Granted it’s not brain surgery, but it’s
useful to many of us, and that would be
a good place to find it. (And after all,
there are things in the RAA that are
nearly useless or nonexistent.)
