Embedding several ruby interpreter instances in C?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello list, the subject says it all: I know how to generally embed Ruby into a C program. However, since ruby_init() & co just return void, I guess there is no way to have more than one Ruby interpreter embedded into the same program at a given time. Am I correct with this assumption?

ruby without framework

[Note: parts of this message were removed to make it a legal post.] Can I use ruby code running in web browser without any frameworks used? Also anyone please tell me how to make framework, Please give me some tips or spark to start with.

Regex breaks when string contains binary data

Hi, I can't see why the following Regex isn't working as expected. Maybe a bug in ruby? puts "345HI".match(/HI|BYE/).inspect > HI puts "\345HI".match(/HI|BYE/).inspect > nil What I expected was the second regex to find "HI" in the string too. Why I need this, is that I'm printing data to stdout that will contain some binary characters, and I'm using a regex to escape the newline characters that it maybe contains. I'm using Ruby 1.8.7 Thanks, Aish -- Posted via http://www.ruby-forum.com/.

Angle Identifier

puts "Enter degree of angle:" measure = gets.chomp.to_i if measure == "180".to_i then puts "That's a straight angle." if measure == 181..359.to_i then puts "That's an obtuse angle." if measure == 91..179.to_i then puts "That's an obtuse angle." if measure == "90".to_i then puts "That's a right angle." if measure < 90.to_i then puts "That's an acute angle." if measure == "360".to_i then puts "That's a circle..." else puts "That's an invalid measurement." end end end end end end This seems like it should work, but sometimes it doesn't.

Odd functional programming question

Ok this is probably not really functional programming but I was just noodling about with Ruby when I thought "it would be quite nice if I could do X". In this case X is as follows: def X(text, action) x.action end >> X("abcedf", size) => 6 >> X("abcdef", upcase) => "ABCDEF" >> X("abcdef", gsub(/[aeiouy]/, '_')) => "_bcd_f" Quite clearly this does not actually work, otherwise I wouldn't be asking. But is there some way in Ruby to do something like this?

Event Resolution Framework

Has anyone ever pursued creating a library/framework for the abstract management of event resolution models? I'm coding a game where character actions of all players are planned ahead of time, and then these actions are executed all at the same time. This, obviously, means that I will need to develop logic to resolve event conflicts. For example, character A decides to send a message to character B, at the same time that character C decides to shoot character A. So my game logic needs to decide which events take precedence (does character A get off his message before getting shot?)

Enumerator#each return value is surprising

Generally in Ruby, if enum is an Enumerable, enum.each returns enum -- this seems to be the case for all enums. But for Enumerator, it seems to return...well, something else. For enumerators created with enum_for, it returns the return value of the underlying function, e.g.: irb(main):065:0> e = [1,2,3].enum_for(:each) => #<Enumerator: [1, 2, 3]:each> irb(main):066:0> e.each {} => [1, 2, 3] While the return value of each is usually not that important (its usually used as if it was a procedure rather than for its return value), shouldn't Enumerator#each return the receiver like A
