Hi Nicolas,
You are right, the syntax of moose chef is more elegant.
But the point of creating a new extension was to offer the option to express more generic
queries.
If you are working on a moose model which represents a Java program, you can easily use
moose chef and get what you need.
But if the model you are analyzing is of a different kind (a famix extension or a generic
moose model) and provides unforseen selectors and entities, what can you do ?
You have to look at Lift as a less domain-bound version of chef, not necessarily as a chef
replacement.
Did i understand your question correctly ?
Does it make sense to you ?

Hk Andrea,
I had a quick look at Lift.
Being able to express the queries on MooseGroups is a nice addon.
But I think it would have been much nicer keeping the syntax of MooseChef.
Instead of:
(aNamespaceGroup lift: #incomingInvocations from:self mooseModel allMethods)
asMooseGroup
why don't you use:
aNamespaceGroup queryIncomingInvocations atNamespaceScope
which according to MooseChef syntax should return the same thing ?
I trust you will agree the second is more elegant , and it has the advantage of keeping
the same syntax, so we don't need to learn a new syntax

Hi,
I developed a small extension which allows to query a moose model to obtain a set of
implicit associations derived from low level relationships.
What you can do concretely is for example to select a group of namespace entities, and
ask for all implicit associations existing between the selected entities based on a
specific relationship existing at a lower abstraction level (i.e.: the method level).
The end result is much similar to the one provided by Moose Chef, with the advantage of
being much more generic and flexible.
Each generated association keeps a reference to the concrete relationships on which it is
based on.
If you are interested, you can try it out at: http://www.squeaksource.com/Lift.html
The wiki page contains some usage examples.
cheers,
Andrea
