Round to two decimal place
Hi
I have a variable say @price. It is either blank or has a value. If
it is blank I have to show it like $ 0.00 . So I wrote helper like
@price.blank? ? '$'+'0.00' : '$'+@price.to_s
But the problem if @price has value 400.00 , after doing
@price.to_s it changes to 400.0 What I want is exactly 400.00 .And if
I remove to_s above it will throw an error
can't convert BigDecimal into String
Please help
Thanks
Tom

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?
TIA!

[ANN] IPAddress 0.7.0 released
Hi,
I've released IPAddress 0.7.0.

This new release is focused on two points:
* compatibilily with IPAddr
almost all IPAddress methods are compatible with their IPAddr
counterpart, with the exception of wrong and flawed methods
* performances improvement
IPAddress is now around 50% faster than IPAddr on all normal tasks. As
an example, this is the speed improvement on initialize and to_s

Small improvements ideas ?
Hello, I would like to know how to shorten these two lines
1) doit() if my_string && my_string.downcase == 'hello'
2) doit() if one_var && (my_string =~ /this_regexp/) == nil
Case 1) is a way to check for my_string beeing nil (would break on
downcase call). But it's verbose, nothing better ??
Case 2) I want doit beeing call if regexp don't match. would I use !
(my_string =~ /this_regexp/) but I don't like using ! because it's not
very readable and I can't use not keyword in this case
Thanks

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.
I need to make a new framework because I need to re-use the ruby code
(actually shares the code) for desktop version and the new framework.
Is that possible?

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

[Newbie] What folder to upload to?
Hi all,
I am reading all the tutorials and trying to dive into ruby here. I have
a remote web server I want to test my programming on but I am used to
just uploading a file (php or .net) and running it in the root folder
for that page. Ruby seems different and I haven't really figured out
this part of it.
I am doing a sinatra tutorial and don't know where to put my files on
the remote web server. Do I put them in the public_html (www) folder or
somewhere else. I managed to get ruby installed on the server using some
SSH.
Can someone point me in the right direction?

Receiving array naturally?
As I learn Ruby, I find a lot of flexibility in the syntax. I was
thinking there was a way to do something like so: Say I had a method
that would receive an array. Is it possible to define the method so that
it can take the array elements /either/ as an Array object, /or/ as a
comma-separated (variable) list of elements (without the brackets)?
Like,
process_data(string1, string2, string3, ...)
would be the same as
string_array = [string1, string2, string3, ...]
process_data(string_array)
I thought something like so would work:
def process_data(*strings)

A gem for web services load testing?
Hi Folks - I've been developing automated functional tests in ruby for
our website for the last few months, and now need to expand my scope.
Before I hit google, can anyone recommend a gem which can perform load
testing on a REST API? I realize I could probably build my own w/
mechanize + threading of some kind, but that seems like it'd be a lot of
work, and I don't want to solve a problem that's already been solved.
Any suggestions are appreciated.

Installed gem does not load

I am attempting run, in 1.8.6, an fxruby sample called babelfish.rb
babelfish.rb requires a gem called tranexp
I installed the gem and
gem list --local produces (in part)
produces
tranexp (1.0.1)
I, of course, tried to run babelfish.rb.
Of course, it wouldn't run ...
- - -
babelfish.rb:4:in `require': no such file to load -- tranexp (LoadError)
from babelfish.rb:4

What would prevent tranexp to load when all other gems load just fine?

Dynamic variables in blocks vs constants
Hi, I know that dynamic variables created in block it is not accessible
from outside of that block but I noticed that dynamic constants can be
accessed and I want to know why it is so.
Sorry for my bad english. For better understanding of my problem I'm
attaching code below.
%w[magic MAGIC].each do |x|
eval <<-RUBY
#{x}_dynamic = 1
RUBY
end
And now you can try..
magic_dynamic
MAGIC_dynamic
You can observe it using 1.9 version of ruby.

Where "best" generally means portable to other people's computers,
where they can be assumed to have a working ruby install of the same

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?

Getting name of current method
[Note: parts of this message were removed to make it a legal post.]
Ruby has __FILE__ and __LINE__ to give the file and line omber where we are currently at in the code.
Consider
Class X
def my_method
m = ??? # I want m to be assigned "my_method"
end
end
How can I get m set properly?
I guess I could use define_method to define my_method and then pass the name into the function .. but that is so ugly and also flattens scope that I may not want flattened.

Getting notification that a subprocess is killed on Windows
[Note: parts of this message were removed to make it a legal post.]
What is the proper way, under Windows, to detect that a process was killed? Crashed?
Signal.list.each_key do |key|
puts key
Signal.trap(key, lambda {|signo| puts "#{key}: pid #{$$} with signo #{signo}"})

@the_command_pipe = IO.popen(the_command)
@the_command_pid = @the_command_pipe.pid
Process.waitpid(@the_command_pid)
@child_process_return_status = $?

Process.kill(:KILL, @the_command_pid) # Seems to properly kill my

Mountain.rb in Boulder Oct6-9 early bird closing Monday
Hi all,
Just a quick note to anyone who doesn't know about this conf. I'm
excited since it's up the way from me in Boulder and has a great speaker
line up including Jim Weirich, Aaron Patterson and others on some really
cool topics. Additional plus is that the country's largest Ignite -
Boulder Ignite is happening one of the nights as well.
There's more info on the site: http://mountainrb.com I just
registered and realized the early bird ends on Monday for what looks to
be a killer conference, figured I'd forward this on to the list. Look me
up if you make it, I'm always up

Matz's slides from Rubykaigi?
Hello,
(I guess this is mostly directed at Matz but I thought of sending it
here since it may interest other people too.)
Would it be possible to have somewhere accessible online Matz's slides
from this year Rubykaigi?
Thank you
Diego

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?)

Uninstall conflicting versions of ImageMagick?
In irb when I enter "require 'RMagick'" I get:
RuntimeError: This installation of RMagick was configured with
ImageMagick 6.5.7 but ImageMagick 6.5.5-10 is in use.
from /usr/lib/ruby/1.8/i486-linux/RMagick2.so
from /usr/lib/ruby/1.8/RMagick.rb:11
from (irb):2:in `require'
from (irb):2
from /usr/lib/ruby/1.8/RMagick.rb:1513
I have upgraded Ubuntu several times (even after formatting the main
partition). I did keep my home partition intact. I also recently
installed rvm. I can't seem to figure out how to uninstall the 6.5.5-10
conflicting version of ImageMagick.

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
