Sorry for the delay... One thing to note is you won't get any warnings like
PyLint provides, but it will let you interrogate the analysis. Here's the
basic code:
string code = "def f(): pass";
// create an interpreter instance and an analyzer for that
interpreter.
var factory = new
IronPythonInterpreterFactory(ProcessorArchitecture.X86); // IronPython specific
//var factory =
InterpreterFactoryCreator.CreateAnalysisInterpreterFactory(new Version(2, 7));
// generic CPython interpreter
var analyzer = new PythonAnalyzer(factory,
factory.CreateInterpreter(), "__builtin__");
// add some code into the interpreter.
var sourceUnit = new StringReader(code);
var entry = analyzer.AddModule("foo.py", "foo.py", null);
using (var parser = Parser.CreateParser(sourceUnit,
PythonLanguageVersion.V27, new ParserOptions() { BindReferences = true })) {
entry.UpdateTree(parser.ParseFile(), null);
}
// analyze that code
entry.Analyze(CancellationToken.None);
// now you can query the resulting analysis
entry.Analysis.GetTypesByIndex("f", code.Length);
To reference this you just need to add a reference to
Microsoft.PythonTools.Analysis for the core analyzer/interpreter support and
Microsoft.PythonTools.IronPython.Interpreter for the IronPython specific
interpreter support (which understands all of the .NET namespaces).
This is just analyzing a single file but you can easily expand it to analyze
multiple files, pull those files off disk, etc...
Hopefully that can get you started... From there you can start digging into
the analyzer code to extend it to support any additional warnings you want.

Could anyone link me on how to use PTVS's analyzer?

Do you want to create your own static analysis rules or just use an existing
checker? If it's the latter you could use PTVS's analyzer (I can point you to
some example code if so). If it's the former we eventually want to add it to
PTVS and when we do that we should pick up IronPython support for free. We'd
also accept it as a contribution ;)

Subject: [Ironpython-users] static analysis tool
I'm trying to static analysis on python code that has very heavy usage of .NET
libraries. I've seen pyflakes, pylint, and pychecker as the main tools to do
this stuff in python, but I haven't gotten any of them working properly with
IronPython in windows.
Are there any recommendations for something that could analyze:
import clr
clr.AddReference("System")
from System import String
stuff = String("my string")
print stuff
stuff.ThisDoesntExist()
without tripping up on the System and String imports and find that
"stuff.ThisDoesntExist()" doesn't actually exist?
Thanks,
Joe
