Subject: eval'ing a config file

Hi,

I have a number of LDAP-related programs that I want to share a common
config file in which certain variables are stored, such as server, port,
password, etc. in the following form.

LDAP_HOST = foo.bar.com
LDAP_PORT = 389
LDAP_PASS = foobar

I want the parser to ignore blank lines and those that start with a '#'.

The code that I've come up with is this:

File.open("/etc/ldaprc") do |f|
  f.each do |line|
    next if line =~ /^(#|$)/ 
    var, val = /^(.+?)\s*=\s*(.+)$/.match(line)[1,2]
    eval "#{var} = '#{val}'"
  end
end

It works, but looking at it, it looks too much like code I might have
written for Perl some years ago. Is there a more Rubyesque way to do
this? In particular, is there a cleaner way than eval?

Ian
