Simple deprecation method that deprecates name by wrapping it up
in a dummy method. It warns on each call to the dummy method telling the
user of repl (unless repl is :none) and the year/month
that it is planned to go away.
# File lib/rubygems/deprecate.rb, line 50
def deprecate name, repl, year, month
class_eval {
old = "_deprecated_#{name}"
alias_method old, name
define_method name do |*args, &block|
klass = self.kind_of? Module
target = klass ? "#{self}." : "#{self.class}#"
msg = [ "NOTE: #{target}#{name} is deprecated",
repl == :none ? " with no replacement" : "; use #{repl} instead",
". It will be removed on or after %4d-%02d-01." % [year, month],
"\n#{target}#{name} called from #{Gem.location_of_caller.join(":")}",
]
warn "#{msg.join}." unless Gem::Deprecate.skip
send old, *args, &block
end
}
