The Zonnon Project: a .NET Language and Compiler Experiment
The Zonnon Project: A .NET Language and Compiler Experiment Jürg Gutknecht Vladimir Romanov Eugene Zueff Swiss Fed Inst of Technology Moscow State University Swiss Fed Inst of Technology (ETH) Computer Science Department (ETH) Zürich, Switzerland Moscow, Russia Zürich, Switzerland [email protected] [email protected] [email protected] ABSTRACT Zonnon is a new programming language that combines the style and the virtues of the Pascal family with a number of novel programming concepts and constructs. It covers a wide range of programming models from algorithms and data structures to interoperating active objects in a distributed system. In contrast to popular object-oriented languages, Zonnon propagates a symmetric compositional inheritance model. In this paper, we first give a brief overview of the language and then focus on the implementation of the compiler and builder on top of .NET, with a particular emphasis on the use of the MS Common Compiler Infrastructure (CCI). The Zonnon compiler is an interesting showcase for the .NET interoperability platform because it implements a non-trivial but still “natural” mapping from the language’s intrinsic object model to the underlying CLR. Keywords Oberon, Zonnon, Compiler, Common Compiler Infrastructure (CCI), Integration. 1. INTRODUCTION: THE BRIEF CCI and b) to experiment with evolutionary language HISTORY OF THE PROJECT concepts. The notion of active object was taken from the Active Oberon language [Gut01]. In addition, two This is a technical paper presenting and describing new concurrency mechanisms have been added: an the current state of the Zonnon project. Zonnon is an accompanying communication mechanism based on evolution of the Pascal, Modula, Oberon language syntax-oriented protocols , borrowed from the Active line [Wir88]. -

The language is largely based on Pascal, but in addition to conventional block ) structure it introduces a so - called module structure . A module is a set of procedures, data types, and variables, where the programmer has precise control over the names that are imported from and exported to the environment. Modula includes general multiprocessing facilities, namely processes , interfacp, modules, and Signals . It also allows the specification of facilities that represent a computer ' s specific peripheral devices . Those given in this paper pertain to the PDP - 11.

Languages and Compilers (Sprog Og Oversættere)
Languages and Compilers (SProg og Oversættere) Bent Thomsen Department of Computer Science Aalborg University With acknowledgement to Microsoft, especially Nick Benton,whose slides this lecture is based on. 1 The common intermediate format nirvana • If we have n number of languages and need to have them running on m number of machines we need m*n compilers! •Ifwehave onecommon intermediate format we only need n front-ends and m back-ends, i.e. m+n • Why haven’t you taught us about the common intermediate language? 2 Strong et al. “The Problem of Programming Communication with Changing Machines: A Proposed Solution” C.ACM. 1958 3 Quote This concept is not particularly new or original. It has been discussed by many independent persons as long ago as 1954. It might not be difficult to prove that “this was well-known to Babbage,” so no effort has been made to give credit to the originator, if indeed there was a unique originator. 4 “Everybody knows that UNCOL was a failure” • Subsequent attempts: – Janus (1978) • Pascal, Algol68 – Amsterdam Compiler Kit (1983) • Modula-2, C, Fortran, Pascal, Basic, Occam – Pcode -> Ucode -> HPcode (1977-?) • FORTRAN, Ada, Pascal, COBOL, C++ – Ten15 -> TenDRA -> ANDF (1987-1996) • Ada, C, C++, Fortran – .... 5 Sharing parts of compiler pipelines is common • Compiling to textual assembly language • Retargetable code-generation libraries – VPO, MLRISC • Compiling via C – Cedar, Fortran, Modula 2, Ada, Scheme, Standard ML, Haskell, Prolog, Mercury,... • x86 is a pretty convincing UNCOL – pure software translation -
Programming with Windows Forms
A P P E N D I X A ■ ■ ■ Programming with Windows Forms Since the release of the .NET platform (circa 2001), the base class libraries have included a particular API named Windows Forms, represented primarily by the System.Windows.Forms.dll assembly. The Windows Forms toolkit provides the types necessary to build desktop graphical user interfaces (GUIs), create custom controls, manage resources (e.g., string tables and icons), and perform other desktop- centric programming tasks. In addition, a separate API named GDI+ (represented by the System.Drawing.dll assembly) provides additional types that allow programmers to generate 2D graphics, interact with networked printers, and manipulate image data. The Windows Forms (and GDI+) APIs remain alive and well within the .NET 4.0 platform, and they will exist within the base class library for quite some time (arguably forever). However, Microsoft has shipped a brand new GUI toolkit called Windows Presentation Foundation (WPF) since the release of .NET 3.0. As you saw in Chapters 27-31, WPF provides a massive amount of horsepower that you can use to build bleeding-edge user interfaces, and it has become the preferred desktop API for today’s .NET graphical user interfaces. The point of this appendix, however, is to provide a tour of the traditional Windows Forms API. One reason it is helpful to understand the original programming model: you can find many existing Windows Forms applications out there that will need to be maintained for some time to come. Also, many desktop GUIs simply might not require the horsepower offered by WPF. -
Using Powershell and Reflection API to Invoke Methods from .NET
Using Powershell and Reflection API to invoke methods from .NET Assemblies written by Khai Tran | October 14, 2013 During application assessments, I have stumbled upon several cases when I need to call out a specific function embedded in a .NET assembly (be it .exe or .dll extension). For example, an encrypted database password is found in a configuration file. Using .NET Decompiler, I am able to see and identify the function used to encrypt the database password. The encryption key appears to be static, so if I could call the corresponding decrypt function, I would be able to recover that password. Classic solution: using Visual Studio to create new project, import encryption library, call out that function if it’s public or use .NET Reflection API if it’s private (or just copy the class to the new workspace, change method accessibility modifier to public and call out the function too if it is self-contained). Alternative (and hopeful less-time consuming) solution: Powershell could be used in conjunction with .NET Reflection API to invoke methods directly from the imported assemblies, bypassing the need of an IDE and the grueling process of compiling source code. Requirements Powershell and .NET framework, available at http://www.microsoft.com/en-us/download/details.aspx?id=34595 Note that Powershell version 3 is used in the below examples, and the assembly is developed in C#. Walkthrough First, identify the fully qualified class name (typically in the form of Namespace.Classname ), method name, accessibility level, member modifier and method arguments. This can easily be done with any available .NET Decompiler (dotPeek, JustDecompile, Reflector) Scenario 1: Public static class – Call public static method namespace AesSample { public class AesLibStatic { .. -
