resolving package object imports

[Brian Kent]

Hi,

Scala IDE (4.0.0-vfinal-20150113-0949-Typesafe) seems to handle importing package objects inconsistently.  Is that a known issue?

Given something like:

package object foo {
  trait Bar
}

if I try to reference Bar in another file and I

trigger autocomplete (cmd-space), then I get the following options in the listing:

"Bar - foo"  (correct)
"Bar - foo.`package`"  (technically correct, but redundant)

use the help/suggestion menu (cmd-1), then I get the following options in the listing:

"Bar - package"  (incorrect)
"Bar - package$"  (incorrect)

I tend to use the cmd-1 option instinctively, so I always have to go back and edit to the correct package.

Any insight would be appreciated.

Thanks!

- Brian

Don't use traits/classes inside package objects. Not only for the IDE, but it's generally discouraged. There's for sure a number of posts on scala-user/internals about why that's bad (implementation restrictions).

Do you have a link? What I could find seems old (<= 2.10.x). (I am using Scala 2.11.5).

My 2.11.5 compiler warns me (using -Xlint):

it is not recommended to define classes/objects inside of package objects. If possible, define trait MyFooTrait in package test instead.

Screenshot attached.

cheers,

Many thanks, Iulian!  I had no idea that was considered bad form.
