This is due to Ruby's dynamic nature; in a lot of cases it is difficult
for the IDE to figure out what's the real type of the receiver, i.e. the
IDE isn't sure about what methods are available for the receiver at
runtime, so it falls back to showing all the methods available in the
project.
Some work has already been done in 6.7 to make the IDE more intelligent
in this respect, and when the IDE thinks it knows the type it displays
the relevant methods first in the code completion dialog. A lot remains
to be done still though - it is actually not too difficult to analyze
method bodies (to figure out possible return types), but to make it fast
enough is a bit of a challenge. In addition there are constructs that
are difficult/impossible to analyze - imagine e.g. a method created
dynamically using class_eval, as in:
Foo.class_eval(some_user_entered_string)
Going forward, I'm hoping to gradually improve the IDE's type inference
so that more and more cases get covered (and hopefully I can make it
faster too), that should help wrt. long code completion lists.
