[ruby] c#-like syntax and others

Rails
1

If I’m not mistaken I’ve read once about ruby’s flexibility in letting
you do something your own way (there is always more than 1 way to do
something and ruby lets you choose your own way).
And yes, syntax in ruby is flexible. But there is a way to write ruby
code in c# style?
writing
1.upto( 2 )
{ | i |
puts i.to_s
}
throws error.

you have to write
1.upto( 2 ){ | i | # just one line here
puts i.to_s
}
to work
It seems here isn’t your way. it’s just ruby way…
Or is there way I dont know to write c#-like code:
function/instruction
begin sign -{-
… block’s code …
end sign -}-

For short blocks, I believe it’s idiomatic to do:

1.upto(2) { |i| puts i.to_s }

This also works but isn’t idiomatic because it puts the ‘|i|’ on its
own line:

1.upto(2) {
|i|
puts i.to_s
}

For longer blocks, it’s idiomatic to use do…end:

1.upto(2) do |i|
puts i.to_s

more work here…

and here…

and so on…

end

However, if you don’t provide the opening ‘{’ or ‘do’ on the same
line as the 1.upto(2), you’ll get an error that no block was given. I
verified this in IRB (interactive Ruby) on Mac OS X w/ Ruby 1.8.5
from MacPorts.

thanks for the reply

i thought maybe there a way to tell ruby interpreter the new line in
fact is not meant to be taken as a new line and that it’s just for code
layout

1.upto( 3 )[a sign for ‘hey, ruby, it’s a dummy new line here’]
{ | i |
puts i
}

Just like there is a sign (–> ; <–) to tell ruby there should be a new
line

1.upto( 3 ){ | i | print 'current: '; puts i }

the code above works fine because there is a --> ; <–; otherwise we get
an error

thank you \ :slight_smile:
Greg

and because there are so many ways to write ruby, is there a obfuscator
to make the code more easy to be executed by ruby interpreter (that,
let’s say, will transform the code from the most readible for you form
to the easiest interpretable form for ruby) (or is it a practice in ruby
world to obfuscate code before moving in production, and if yes, is
there a significant performance gain)?
