Greetings,
I'm working with Nicolas Arnaud-Cormos on developing a scripting interface to
Qt Creator[1]. Our hope is to lower the bar for automating tasks.
I'm currently trying to get my hands on the AST for a given file, so I e.g. can
tell which method and class I'm in. I have some trouble getting a valid AST,
despite hours of browsing the code.
Here is what I currently have:
I believe that my luck is made, as soon as I can get something valid out of
ASTPath::operator(), which returns a list of AST*, so I'm working backwards
from that.
// Fetch information about line, coumn and file name
Core::IEditor* editor = Core::EditorManager::instance()->currentEditor();
const int line = editor->currentLine();
const int column = editor->currentColumn();
const QString fileName = editor->document()->fileName();
// Fetch document content
QFile file(editor->document()->fileName());
file.open(QFile::ReadOnly);
const QByteArray content = file.readAll();
// Get a Document pointer
CPlusPlus::Snapshot snapshot =
CPlusPlus::CppModelManagerInterface::instance()->snapshot();
CPlusPlus::Document::Ptr document = snapshot.documentFromSource(content,
fileName);
const bool ok = document->parse(CPlusPlus::Document::ParseTranlationUnit);
// OK, I'm desperate, so lets wait a bit in case something needs to
initialize asyncronic
QTime time;
time.start();
while ( time.elapsed() < 2000 )
qApp->processEvents(QEventLoop::AllEvents, 100);
// Give me an AST, please
QList<AST *> path = ASTPath(document)(editor->currentLine(),
editor->currentColumn());
qDebug("Result:\nFileName: %s\nColumn: %d\nLine: %d\nParsed OK: %d\nLength
of result from ASTPath: %d", qPrintable(fileName), column, line, ok,
path.count());
Now, I try to execute this code on a C++ file loaded from a valid QMake
project. The result is:
Result:
FileName:
/home/blackie/Klaralv/training-material/addon/dialogs/sol-orderform/orderform.cpp
Column: 25
Line: 28
Parsed OK: 1
Length of result from ASTPath: 0
Everything seems OK, still I don't get any AST's back.
Any hints on what I do wrong, or even better on how to do it right would be
greatly appreciated.
Kind Regards
Jesper.
