Question

I don t know if this is a ruby question or a Sinatra question, because I m new to both. The following code does not work, and I understand why, because the first my_variable is local to its block. I just don t know the syntax for getting it right.

require  rubygems 
require  sinatra 

configure do
    my_variable = "world"
end

get  /  do
    "Hello " + my_variable
end

EDIT1 - the following works, but then I guess I m confused about the proper purpose of the configure block.

require  rubygems 
require  sinatra 

my_variable = "world"

get  /  do
    "Hello " + my_variable
end

Answer 1

require  rubygems 
require  sinatra 

set :my_variable, "world"

get  /  do
  "Hello " + settings.my_variable
end

Answer 2

Configure block is just to app configuration related. If that s what it is, you should encapsulate it proper:

require  sinatra 

configure do
  set :my_option, "world"
end

get  /  do
  "Hello #{options.my_option}"
end

Answer 3

One other way is :

require  rubygems 
require  sinatra 

@my_variable="world"

get  /  do
  "Hello " + @my_variable
end

Answer 4

I would set a class variable — eg. @@my_variable — inside the configure block. The configure block exists for code you want to run at start up, so setting your variable their makes sense. Your Sinatra application is a subclass of Sinatra::Base, so using a class variable in this situation seems appropriate.
