Description

Move assistant infrastructure to kdevplatform

Noteworthy changes:
* StaticCodeAssistant (from CPP plugin) is now StaticAssistantsManager,
  now lives in  kdevplatform, so all languages can benefit from it
* RenameAssistant was moved to kdevplatform, as it it useful for all
  languages
* BasicRefactoring now has new virtual methods that control the behavior
  for renaming actions
  LanguageSupport got a new property: refactoring (so languages can expose
  their custom BaseRefactoring implementation)

New API:
* New base class for "static" assistants: StaticAssistant
  Static assistants exist during the whole session
  They are notified when documents change and create solutions based on
  that. Current implementations: AdaptDefinitionSignatureAssistant (CPP
  language) and RenameAssistant (kdevplatform)
* New manager class: StaticAssistantsManager:
  Tracks the StaticAssistant instances, takes care of notifying them
  about changes in the editors. Single entry point for registering
  StaticAssistants.
  Entry-point: LanguageController::staticAssistantsManager

Testing Done

Note: This is by far not a 1:1 copy of the stuff from KDevelop, it needed quite some adjustments. The RenameAssistant in kdevplatform is now language-agnostnic, and its behavior is influenced by BasicRefactoring (which in turn belongs to a language support plugin).

TODO: Pimpl the new classes.

I'd like to have some feedback about the initial design of the new API in kdevplatform.

Ship it!

It's great to see this work done. I was suspicious about reusing StaticCodeAssistant, but this looks like a good cleanup that Solves Real Problems. It's much simpler to follow the logic now.

Maybe add braces to the one-line if statements before the style-nazi gets to it.

This code was written with the assumption that textChanged will always come from the same view, is it possible here to begin editing the same range in another view and bypass this reset?

looks cool to me, some style issues and of course the missing pimpl stuff.

did you try it out with non-c++ language plugins like PHP with its $foo-like variables?

Kevin Funk June 9, 2014, 9:28 a.m.

Note: Doesn't work with the PHP plugin (didn't look deeper into it yet). However, the rename assistant didn't show up before my patch either. Can you confirm?

Doesn't really qualify for auto, imo.

yay in principle.

but: should this be a list or something? could an assistant not support multiple languages or should we keep it as-is and let multiple assistants be registered for every language?

not opening an issue, just want to know your input on that

Kevin Funk June 9, 2014, 9:21 a.m.

Yes, I'd keep it as-is. Having just one language per assistant makes it much easier to manage, imo. Each language can then decide whether it wants to instantiate a RenameAssistant.
