Hi I got a very noob question which i cant understand why i cant do  
things like this…

eg… inside.  
helloworld.rhtml

\<% puts "hello" puts "world" puts "something something" %\>

I know i can do this easily in php

\<?php echo "yes this works" echo "testing 123" echo "yes this works" ?\>

Can someone help me?

It’s a simple as:  
\<%= “hello world!” %\>

hmmm  
so means that for my program

helloworld.rhtml

\<%= puts "hello" %\> \<%= puts "world" %\> \<%= puts "something something" %\>

i have to do that? that is obviously way harder to code…  
and if it was in between a loop or something just say for debugging…  
i got to close the loop and then bracket it… then come back again?  
man  
there must be an easier way???

I’m not sure if this helps or even if it’s good  
I don’t like to open and close with \<%…%\> repeatedly.  
So I use the following.

\<%  
\_erbout \<\< “hello”  
\_erbout \<\< “world”  
\_erbout \<\< “something something”  
%\>

Not exactly, you do this:

\<%= "hello" %\> etc...

\<%= is roughly analogous to “puts” or “print”

ERB doesn’t allow you to use ‘print’ or ‘puts’ in eRuby script.  
You can use print statement if you use Erubis instead of ERB.  
Erubis is an implementation of eRuby which has some advantages over  
ERB.  
[http://rubyforge.org/projects/erubis/](http://rubyforge.org/projects/erubis/)

For example, the following code is available with Eruby::PrintEruby  
or Eruby::StdoutEruby class.

\<% print "hello\n" print "world\n" print "something something\n" %\>

See doc/users-guide.html in the archive.

A better example would be

if i was to do some debugging  
it would have to be

\<% @articles.map { |x| %\>  
\<%= x.name %\>  
\<% } %\>

instead of  
\<%= @articles.map { |x| echo x.name } %\> ???

wouldnt that be so difficult to type out and to read as well?
