Hello,
please have a look at 23.7.1 of the CLIM 2.0 specification. In the section about DEFINE-PRESENTATION-TRANSLATOR it says:
...
If my interpretation is correct, you have not only to use theses names *literally* (because of the STRING-EQUAL requirement), but also the empty list is not allowed and the first argument is always required and has to be (STRING-EQUAL to) OBJECT.
I added an ASSERT to beginning of CLIMI::MAKE-TRANSLATOR-LL because I've made the error earlier to try to bind the object to a symbol non-equal to OBJECT, and I've seen that there are presentation translators in beirc that just try to bind PRESENTATION. The ASSERT is:
...
Well, afterwards McCLIM doesn't compile anymore. There are two presentation to command translators in dialog.lisp: COM-EXIT-BUTTON and COM-ABORT-BUTTON.
...
Personally I think the requirement that the arglists have always to be at least the list (object) (if I interpret the spec correctly) is
...
The "canonical" argument list should be the following in my opinion: (&key object presentation context-type frame event window x y) And also the empty list should be considered to match it.
What do you think? Should we just CLIMI::MAKE-TRANSLATOR-LL leave as it is, and add this to a list of known but wanted nonconformances to the CLIM specification?
I believe the code implements the description of translator arglists on page 156 of the Franz CLIM User's guide, which is the closest thing to a reasonable revision of the spec:
"An argument list that must be a subset (using STRING-EQUAL ...) of the canonical argument list: (object presentation context-type frame event window x y)"
In other words, nothing is special about object. Code written to the older definition in the Spec should be compatible with this too.
