[Moose-dev] MooseChef 1/4, a small DSL to query dependencies between famix entities

MooseChef is a new package which provides a small DSL to query (some of the) dependencies between famix entities. It is a replacement for the current Moose Cook project, which provides 'navigation methods' between famix entities and resides in the Famix-Extensions package. Basically, MooseChef provides an API with a few methods to ask a method, a class, a package, a namespace for its dependencies (invocations, inheritance, references...) to other entities at various scope (class, package, namespace). Moose Chef comes as a small set of composable queries, with a well defined meaning, which is easy to browse and understand, and reused across Famix entities through traits. *** Source, side, and dependencies To start with, a query has a source (or receiver), that is the famix entity for which we require dependencies. Currently FamixMethod, FamixClass, FamixPackage, and FamixNamepace supports Chef queries. Relative to the source, a query has a side: it can be a query on either incoming or outgoing dependencies. Primitive queries returns a set of dependencies related to the source, that is instances of FamixAssociation: invocations, accesses, inheritances, references. *** Primitive queries to access dependencies as associations Hence, the combination of sides and dependencies define the set of primitive queries availble for any source. source query[Incoming|Outgoing][Invocations|SureInvocations|Accesses|References|Inheritances]. You can ask for example aFamixMethod queryIncomingInvocations but also aFamixClass queryIncomingInvocations aFamixPackage queryIncomingInvocations (Notice that a few queries do not make sense for some receiver, like for example asking a FamixMethod for its inheritances or it incoming references - in this case the convention is to return the neutral value, that is an empty collection). Some 'composite' queries are also defined on top: all dependencies, sure dependencies, static dependencies : accesses + references + inheritances sure dependencies : static + sure invocations all dependencies : static + invocations -- Simon Denier
