Following improvements in the core of EclipseFP and BuildWrapper, autocomplete in EclipseFP 2.3.0 manages to give you proposals coming from other modules from your project, and adding the relevant imports on the fly if needed. However, there were already concerns about autocomplete giving back a lot of proposals and feeling cluttered. The preference of restricting the proposals to only those coming from existing imports or only to the packages referenced in the project cabal file applied all the time, so it wasn't easy to balance between the two concerns of power and clarity.
So I've made the following change: the preference is gone. Instead you can choose what you want at runtime, in the fashion of Java completion proposals. So let me show you how it works now.
First of all, if you trigger "content assist" without a prefix, you only get the list of symbols the current module knows about: functions defined in the module and in imported modules, because it would be too much to bring back everything. In this case, you get a simple list:
If you have a prefix, you get first the list of known symbols:
But pressing Ctrl-Space again shows you symbols from other modules in your project or packages you have referenced in your cabal file (it shows you the module name after the function name):
And you can press Ctrl-Space again to get all matching symbols in packages you haven't indicated in your cabal file (you can see the package name before the module name):
Of course, pressing Ctrl-Space again brings you back to the initial list.
Hope this answers the concerns people had, and will make EclipseFP more pleasant to use.
Oh, and I don't have a date for the 2.3.0 release, but hopefully sometime this summer. I still need to build the rename functionality (now I have search working, so rename shouldn't be too difficult to implement).
Happy Haskell Hacking
