I\'m new to Ruby. I\'m at the stage where I\'m unsuccessfully attempting to write things in Ruby as I would in some other language.
Emacs 24 now has lexically-scoped variables. It also still has dynamically-scoped variables, of course. Now that it has both, I\'m quite confused about when a variable will have which kind of scope. T
In my experience, it is rarely/never necessary to set scope=\"request\" on an EL variable. For example, I have a page that, given an item parameter, constructs a URL specific to that item based on it
It seems that it\'s cleaning up the pad too early: sub search { my ( $self, $test ) = @_; my $where; my $found= 0;
I try to understand lexical-scoping. In lexical-scoping, I have this code, C like syntax: main{ f1(){ int y = 8;
In lisp I can bind free variables bound in a closure like this... (let ((x 1) (y 2) (z 3)) (defun free-variables () (+ x y z)))
How long does the memory location allocated by a local variable in Perl live for (both for arrays, hashes and scalars)? For instance:
I used to wr开发者_如何学JAVAite let-like expressions -- with lexical scope. So I write my own (sad, but it will fail with multiple threads):
So I\'m new to programming and I\'m trying to learn JS with the book Eloquent Javascript. So far so good, until I reached an example with the following code
From the "our" perldoc: our has the same scoping rules as my, but does not necessarily create a variable.
