Re: [anjuta-devel] The new parser-engine Plugin

[Moritz Lüdecke <ritze skweez net>]

Hi Johannes,

Last two days I tried to run my code. But I fail always at the same 
point as in the past: The language-support plugins have to communicate 
with the new parser-engine plugin.

At the very beginning I used two interfaces. One for the parser-engine 
plugin and one for the language-support plugins. Than I'd problems with 
null pointer every time, when I need the interface object to call 
methods of the interface.

Just under two weeks ago I tried to use only one interface. But the 
problem is, that the parser-engine plugin, which realise 
IAnjutaProvider, executes methods of the language-support plugin. (see 
IAnjutaCalltipProvider)

The language-support plugin starts a async search for the completion 
proposals and the calltip part. For completion proposals the 
language-support plugin executes the method 
"ianjuta_editor_assist_proposals" with a provider object after the 
search is complete and was successful. But the provider object is a 
different as used in the parser-engine plugin.

In this case the list of completion proposals is useless, because 
IAnjutaProvider is realise in the parser-engine plugin and as I already 
said, this class holds another provider object.

I went back to the roots and I tried it with two interfaces again:
 * IAnjutaCalltipProvider: to execute methods, which are realised in 
the language-support plugin
 * IAnjutaProviderAssist: to execute methods, which are realised in the 
new parser-engine plugin

The language-support plugin executes methods from the parser-engine 
plugin after a completed and successfully search. Then the parser-engine 
plugin executes "ianjuta_editor_assist_proposals" with the right 
provider object.

And now my problem: How can I get an interface object of 
IAnjutaCalltipProvider for the parser-engine plugin and an interface 
object of IAnjutaProviderAssist for the language-support plugin at the 
same time? In this way the two plugins are dependent on each other, 
because the parser-engine plugin realises the IAnjutaProviderAssist 
interface and the language-support plugin realises 
IAnjutaCalltipProvider interface.

I hope that I could express myself clearly enough.

Moritz
