Hi everyone,
I have a simple class implementing IScriptBuilder and noticed, that it
is being called 4 times on full project rebuild by DLTK's ScriptBuilder.
First time - with correct list of ISourceModule's and
IScriptBuilder.FULL_BUILD status and 3 more times with
IScriptBuilder.FULL_BUILD (1 time) and IScriptBuilder.INCREMENTAL_BUILD
(2 times) with empty list of ISourceModule's.
Is it a bug and if it is not, how IScriptBuilder implementing class
could understand a state it is in - how to differentiate a case, when
all modules were removed from the project from a case when it is just
being called for some reasons from ScriptBuilder with empty list of files?
Thanks
Tatiana

What I'd like to know is when/how the project source modules are parsed and
turned into model elements. I know this happens via the reconciler, which
happens at least when you make changes to the working copy in the editor,
and via the indexer. I thought that perhaps this did or should happen via a
builder - but upon closer inspection this doesn't appear to be the case.
Thus, I am in the process of trying to write code for the builder to:
a) parse each source module element (and turn it into corresponding models)
b) run our custom semantic checker
Per your recommendation, I already moved the semantic checker into
ISourceElementParser.parseSourceModule (rather than ISourceParser.parse).
So, I thought I should call my existing method that already does what I
want.
When I looked at who called parseSourceModule, I found that it is called by
SourceParserUtil.parseSourceModule. That method is called by
AbstractSourceModule.buildStructure.
I have a few questions (besides the ones implied above):
0) Should my builder be doing parsing and model building - or is that
done automatically from something else?
1) How do I determine the nature ID for a project/source-module/parser?
I can get the list of nature ids for a project from its project
description.
Some methods I want to call take a nature id, and others take
IModelElement.
For example, I was calling DLTKLanguageManager.getProblemFactory().
2) Do I need to set the parser's (ISourceElementParser) problem
requestor?
If so, how do I create it?
Thanks,
Chuck

Apparently the issue to this question is yes I do - otherwise there is a
null pointer exception.
If I can't figure this out, then perhaps I will
a) get the ISourceParser instead and call parse (calling
SourceParserUtil.getModuleDeclaration)
b) call my semantic checker directly

Apparently, I can call:
a) IDLTKLanguageToolkit toolkit =
DLTKLanguageManager.getLanguageToolkit(module);
b) String natureId = toolkit.getNatureId()
