detecting a method defined within the SDK

[Draycos Goldaryn]

Ok, I'm using unless Object.const_defined?SDK)[/FONT] to detect the sdk. if the sdk has not been defined, my script will then emulate SDK.enabled?(script)[/FONT] in order to enable the script. the problem is that when multiple scripts run this, each script after the first will always return true then run an error when they try to log the script. I tried to add SDK.method_defined?log)[/FONT] but that returns false even if the SDK is installed, I tried SDK.method_defined?SDK.log)[/FONT] but that encounters an error. SDK.method_defined?self.log)[/FONT] also does not work.

I've found a workaround by using SDK.const_defined?PARTS)[/FONT] but was wondering, am I doing something wrong with the aforementioned commands?

Let me rephrase my question:

Why does the following not work? And how can I make it work if i can?

module SDK
  def self.log
    #do this
  end
end

SDK.method_defined?(:log)
  # returns false
SDK.method_defined?(:self.log)
  # Error :undefined method `log' for :self:Symbol
SDK.method_defined?(:SDK.log)
  # Error :undefined method `log' for :SDK:Symbol

Nevermind, I think i figured out why they didn't work. SDK.log is not an ordinary method, but a singleton method. I can detect it if i do the following:

If SDK.singleton_methods.include?("log")
  print "Yes, SDK.log is defined."
end

Try this code:

p SDK.singleton_methods.include?("log")

You can also use the methods Trickster suggested or the one DerVVulfman suggested:

 module SDK
    # SDK not installed
    $sdk_defined = false
    if defined?(log_alias)
      # SDK installed
    $sdk_defined = true
    end
  end

DerVVulfman's suggestion

or

begin
  SDK_AUTO_DETECT = SDK::Version
rescue
  SDK_AUTO_DETECT = nil
end

Trickster's suggestion

Due to its elegance and simple construct... I recommend Trickster's version.

As Trickster suggested, Seph may perform rewrites that could add or remove routines in the SDK and my earlier version relied on detecting the log_alias routine. If a later version of the SDK doesn't include this routine, the detection wouldn't work.

Trickster's version doesn't rely on that and is shorter by contrast.
