ruby-1.8

I may be approaching this in the wrong direction, so any help would be appreciated. I have a Ruby script which, amongst other things, starts up an executable. I want to start this executable - currently being triggered using system "" - and then continue on with the script. When the script finishes, I want it to exit but leave the executable running. Originally I had the following # Do some work # Start the executable system("executable_to_run.exe") # Continue working But executable_to_run.exe is a blocking executable, and system "" will not exit until the executable finishes running (which I

I have an app, which implements a group feature. Each group has n members. Also, each group has a group specific profile pic to it. I have been able to implement auto complete for the group feature keeping in mind the group name alone. I have referred to the following tutorial for the same:- http://railsforum.com/viewtopic.php?id=23188 I am using ruby 1.8.7 and rails 2.0.2 for project specific purpose. I have installed the auto_complete plugin in the appropriate directory. I am on Ubuntu 10.04 OS I would like to integrate two more things as part of the current auto complete feature for groups

So far, I've been merely using YARV (ruby 1.9) as merely a faster implementation of ruby than ruby 1.8, and ensured that all of my code is backwards-compatible with ruby 1.8.6. What circumstances, if any, are stopping you from writing 1.9-specific code? One reason per answer. neutrino Also, if we're talking about rails, then the problem there is the compatibility of gems/plugins with ruby 1.9. I'm sure everyone who wants to upgrade to 1.9 keeps an eye on isitruby19.com The first release candidate for Ruby 1.9.2 is due end of May and I believe many are waiting for 1.9.2 to hop on the 1.9 train.

[ruby 1.8] Assume I have: dummy "string" do puts "thing" end Now, this is a call to a method which has as input arguments one string and one block. Nice. Now assume I can have a lot of similar calls (different method names, same arguments). Example: otherdummy "string" do puts "thing" end Now because they do the same thing, and they can be hundreds, I don't want create an instance method for each one in the wanted class. I would like rather find a smart way to define the method dynamically at runtime based on a general rule. Is that possible? Which techniques are commonly used? Thanks I'm

In some scenario of Ruby 1.8. If I have a hash # k is name, v is order foo = { "Jim" => 1, "bar" => 1, "joe" => 2} sorted_by_values = foo.sort {|a, b| a[1] <==> b[1]} #sorted_by_values is an array of array, it's no longer a hash! sorted_by_values.keys.join ',' my workaround is to make method to_hash for Array class. class Array def to_hash(&block) Hash[*self.collect { |k, v| [k, v] }.flatten] end end I can then do the following: sorted_by_values.to_hash.keys.join ',' Is there a better way to do this? Hashes are unordered by definition. There can be no such thing as a sorted Hash. Your best bet

I need to count the duplicates, they need to be 100% identical to increase my count, but I can not use a nothing out of Ruby 1.8.5, this code will run inside a plugin in google sketchup Google Sketchup Ruby API puts VERSION 1.8.5 puts RUBY_PLATFORM i686-darwin8.10.1 product = 'Glass' x = width y = length z = density product_list = [ { "product" => 1, "x" => 200, "y" => 100, "z" => 18}, { "product" => 1, "x" => 200, "y" => 100, "z" => 18}, { "product" => 1, "x" => 300, "y" => 100, "z" => 18}, { "product" => 2, "x" => 300, "y" => 100, "z" => 18}, { "product" => 2, "x" => 100, "y" => 100, "z" =>
