ldap-filter

While working on a Rails application that leaned heavily on my school's LDAP server, I started off writing inflexible methods like:

def uid_filter(uid)
  "(uid=#{uid})"
end

def uid_or_email_filter(uid, email)
  "(|(#{uid_filter(uid)})(#{email_filter(email)}))"
end

And decided it would be easier to do:

filter = LDAP::Filter::Base.new :uid, 'mrhalp' # (uid=mrhalp)
if search[:email] # mrhalp@email.org
  email = LDAP::Filter::Base.new :mail, search[:email]
  filter = filter | email
end
MyLDAPLibrary.search filter.to_s # (|(email=mrhalp@email.org)(uid=mrhalp))

You also don't have to worry about all those nested parentheses.

Install
