def foo
"foo"
end
alias foo2 foo
puts "foo2: " + foo2.object_id.to_s
puts "foo: " + foo.object_id.to_s
In the above example, I expected to see the same object_id output for each method call since they reference the same method. Why do I see different object_id's? When you alias a method in Ruby doesn't the alias refer to the origi...
I am trying to verify my understanding string interpolation and string templating.
Is it correct to say that the two Java code snippets are examples of templating?
public class Person {
//showing only relevant code
public String toString() {
return "Name: " + name + " salary: " + salary + " address: " + address;
}
}
public S...
G'day,
Why am I getting the following two errors from the script fragment below?

I'm working on a simple string manipulation DSL for internal purposes, and I would like the language to support string interpolation as it is used in Ruby.
For example:
name = "Bob"
msg = "Hello ${name}!"
print(msg) # prints "Hello Bob!"
I'm attempting to implement my parser in ANTLRv3, but I'm pretty inexperienced with using ANTLR...

I Have a Bean like

What could generate the following behavior ?
>>> print str(msg)
my message
>>> print unicode(msg)
my message
But:
>>> print '%s' % msg
another message
More info:
my msg object is inherited from unicode.
the methods __str__/__unicode__/__repr__ methods were overridden to return the string 'my message'.
the msg object was initiali...
I have a python logger set up, using python's logging module. I want to store the string I'm using with the logging Formatter object in a configuration file using the ConfigParser module.
The format string is stored in a dictionary of settings in a separate file that handles the reading and writing of the config file. The problem I ha...
In perl suppose I have a string like 'hello\tworld\n', and what I want is:
'hello world
'
That is, "hello", then a literal tab character, then "world", then a literal newline. Or equivalently, "hello\tworld\n" (note the double quotes).
In other words, is there a function for taking a string with escape sequences and returning an eq...

I could've sworn I saw some articles a while ago about imperfect but useful string interpolation methods for C, but no such luck right now. However, there's Razor, which does more or less what I want.
