Embedded Ruby without Rails

Hi. I started learning ruby and ruby on rails last week. I have a lot of experience with C and perl, including database manipulation with via cgi and using perl to generate javascript, etc.

Ruby seems very nice, but I am starting to find the rails class=table concept repulsive. Also, I do not need rails to do what I want *if* embedded ruby remains feasible. It is not clear to me how realistic that is: can I set out that way and expect to get server support? How? Or is the erb limited to a rails framework, and I should just go learn php instead?

ERB is part of Ruby proper. You can use it without any attachment to Rails. For example:

Code:

irb(main):001:0> require 'erb'
=> true
irb(main):002:0> erb_str = "<%= x %>"
=> "<%= x %>"
irb(main):003:0> template = ERB.new erb_str
=> #<ERB:0x35b394 @safe_level=nil, @src="_erbout = ''; _erbout.concat(( x ).to_s); _erbout", @filename=nil>
irb(main):004:0> x = 42
=> 42
irb(main):005:0> puts template.result binding
42
=> nil
