[Qt-creator] getting AST from a document

[Marek Jasovsky]

Hi all, hi Roberto

I have finally managed my plugin and mode work, but now I can not get ast of
current document.

first version of code crashed when trying to convert ast to
TranslationUnitAST. then, I found out, that translationUnit for the document
had already been released.


   1. TranslationUnit *tu = doc->translationUnit();
   2.
   3.     if (tu)
   4.     {
   5.         AST* ast = tu->ast();
   6.         qDebug("before tu->control()");
   7.         DumpAST *dump = new DumpAST(tu->control());
   8.         qDebug("after tu->control()");
   9.         //ast->accept(dump);
   10.
   11.         if (ast->asTranslationUnit())
   12.             ast->asTranslationUnit()->accept(dump);
   13.     }


unfortunately as seen below, I was neither able to parse the document once
more, as the code crashed in MemoryPool::allocate which is inline function.
(ptr pointed to 0x0010)

if (tu && doc->fileName().endsWith(".cpp"))

{

 if (!tu->memoryPool())

{

doc->parse();

tu = doc->translationUnit();

AST* ast = tu->ast();

DumpAST *dump = new DumpAST(tu->control());

//ast->accept(dump);

TranslationUnitAST *tast = ast->asTranslationUnit();

//dump->accept(ast->asTranslationUnit());

//ast->asTranslationUnit()->accept(dump);

}

}

I have seen, that CppModelManager is parsing sources similar way , I was.
could you please point me, to the right way, how I can get ast of document,
that already has been parsed, and it's translationUnit has been released?

thanks

Marek
