Hi,
assume this simple inductive definition:
inductive foo :: "nat ⇒ bool" where
foo1: "foo 0"
Now, trying the completion:
thm foo<Ctrl-B>
... this gives me "foo.cases", "foo.induct", ... (as expected), and also
"foo1". It doesn't give me "foo.foo1", though.
Peter suggested that the general policy seems to be that if the short
name is in scope, the longer name gets filtered out. Adding another
inductive which introduces another "foo1" rule confirms that observation.
inductive foo2 :: "nat ⇒ bool" where
foo1: "foo2 0"
thm foo<Ctrl-B>
... now has "foo.foo1", but not "foo2.foo1".
Could this be changed or configurable? Sometimes, it is preferable to
give the long names, even if the shorter ones are in scope.
Side note: Pressing <Ctrl-B> after "thm foo." (notice the dot) doesn't
open the completion dialog.
Cheers
Lars

This corresponds to certain canonical ways to deal with internal vs.
external names in name spaces. The bahaviour comes out naturally without
further ado, and without rethinking the usual ways.

To do different one needs a clear counter-indication that the default is
not right. Lets say 2-3 convincing application scenarios. Configurable
"modes" are a measure of last resort, when there is no clear uniform
approach anymore.

The dot is a keyword and already complete on its own. If you want to
complete the name fragment "foo." you have to write it in quotes, and it
then gets correctly expanded without quotes.
