iRules syntax checker / validator

I'm not sure what you are asking about. There already is a syntax checker & validator incorporated in the product. It currently will prevent loading of a rule that fails basic syntax checks, object dependencies (eg, whether a pool exists or not), and command/event dependencies (eg, using the right command in the right event).

Perhaps you have previously disabled the validator and it's not running. The validation is controlled by the BigDB variable "Rule.Validation". It can have the following settings:

 
 strict: performs syntax checks, object dependency and command/event dependency checks and fails to load if any checks are invalid (this is the default). 
 check: performs syntax checks and object dependency checks only. 
 syntax: performs only syntax checks. 
 none: completely disables the validation. 
 

We are also working on a Rule Builder wizard to help construct a majority of basic rules that will soon be made available here on DevCentral for Beta testing.

Hope this helps.
