A metaprogramming METHOD AND ITS ECONOMIC JUSTIFICATION

IEEE TRANSACTIONS ON SOFTWARE ENGINEERING 1986年第2期12卷 272-277页

作者： LEVY, LS AT&T Bell Laboratories Piscataway NJ 08854

metaprogramming, defined as developing application programs by writing programs that produce programs, is presented as the basis of a method for reducing software costs and improving software quality. The method begins with a phase in which selected representative parts of the application are developed into prototypes. This stage is followed by a ''tooling up'' phase, during which the metaprogramming takes place. The final stage is the production of the application programs employing the software tools and methods of the metaprogramming phase. A summary is presented of the experience of 2 projects that support the assertion that metaprogramming is an efficient method to produce programs. Outlines of an economic theory that justifies this approach are presented. A technique for performing a cost/benefit analysis of the method is demonstrated.

Improving the quality of earlier created, legacy software and adjusting those to meet new functional and performance requirements is one of the biggest challenges these days in the field of software engineering. The problem to be solved seems to be pretty straightforward: modifying the existing source code and then extending, and enhancing it with new functionalities. In order to accomplish this task, program elements have to be identified and then used to create the formal model of the program. metaprogramming is a well-known and suitable technique for implementing these changes. Authors' aim was to develop a metaprogramming framework which can be used to transform transient Java applications into persistent ones. Persistency is managed by ObjectStore PSE Pro, a personal storage edition for Java, making persistent data available to programmers in a familiar, normal Java object fashion. Managing the ObjectStore components requires only minor modification of the transient code and the insertion of some code stubs. In the present article authors introduce the infrastructure, its main features, and the prototype system created.

Meta-programming is generally based on a formal software model. The developer creates a model (analyzer) usually from source code, and then the modified model (transformator) is turned back into source code (generator). The formal model is determined by two factors: the source code of the software and the set of model transforming operations characterized by their use cases. An effective Meta-programming system requires a tool, which automates the construction of analyzers and generators. The input of this tool, called "meta-generator", is a representation of a yielding between the grammar syntax of the programming language and the operations related to the elements of a meta-model. The meta-model defines model elements which reflect the use-cases of the model transformations demanded. The output of the meta-generator consists of three programs: the analyzer, the source generator and the transformation library template. This paper introduces the MOFCOM meta-programming architecture.

There are a wide array of methods for writing code generators. We advocate for a point in the design space, which we call metaprogramming with combinators, where programmers use (and write) combinator libraries that directly manipulate object language terms. The key language feature that makes this style of programming palatable is quasiquotation. Our approach leverages quasiquotation and other host language features to provide what is essentially a rich, well-typed macro language. Unlike other approaches, metaprogramming with combinators allows full control over generated code, thereby also providing full control over performance and resource usage. This control does not require sacrificing the ability to write high-level abstractions. We demonstrate metaprogramming with combinators through several code generators written in Haskell that produce VHDL targeted to Xilinx FPGAs.

The increasing complexity of new parallel architectures has widened the gap between adaptability and efficiency of the codes. As high performance numerical libraries tend to focus more on performance, we wish to address this issue using a C++ library called NT2. By analyzing the properties of the linear algebra domain that can be extracted from numerical libraries and combining them with architectural features, we developed a generic approach to solve dense linear systems on various architectures including CPU and GPU. We have then extended our work with an example of a least squares solver based on semi-normal equations in mixed precision that cannot be found in current libraries. For the automatically generated solvers, we report performance comparisons with state-of-the-art codes, and show that it is possible to obtain a generic code with a high-level interface (similar to MATLAB) which runs either on CPU or GPU without generating a significant overhead.

Flexible metaprogramming and AOP in Java

Advanced programming techniques such as metaprogramming and computational reflection, as well as the more recent paradigm of aspect-oriented programming (AOP), serve important objectives of software engineering such as modularization and adaptability. In this tool presentation paper, we briefly overview this area and present Reflex, a portable tool for flexible metaprogramming and AOP in Java. Reflex provides both structural and behavioral facilities adopting a uniform model of partial reflection. This allows selective and fine-grained control of where and when reflection occurs. The facilities of Reflex make it easy to experiment with (combinations oo advanced uses of AOP and reflection without reinventing the wheel or being limited to a specific AOP language.

Application of metaprogramming and Generic Programming in Multiscale Modeling

COMPUTING IN SCIENCE & ENGINEERING 2018年第6期20卷 81-94页

作者： Maciol, Piotr Michalik, Kazimierz AGH Univ Sci & Technol Krakow Poland

Numerical modeling is a tool commonly used by both researchers and engineers. For several reasons, the quality of scientific codes frequently deprecates. One of the possible remedies is the application of advanced programming and software development methods. In this paper, we introduce the application of metaprogramming and generic programming in C++ to control the correctness of multiscale models. Additionally, it is shown how both methods increase reusability and quality of the code. A short introduction to metaprogramming and generic programming is included, as well as the proof of the concept. Exemplary codes are also included and discussed.

Efficient runtime metaprogramming services for Java

JOURNAL OF SYSTEMS AND SOFTWARE 2019年第0期153卷 220-237页

The Java programming language and platform provide many optimizations to execute statically typed code efficiently. Although Java has gradually incorporated more dynamic features across its versions, it does not provide several metaprogramming features supported by most dynamic languages, such as structural intercession (the ability to dynamically modify the structure of classes) and dynamic code generation. Therefore, we propose a method to add those metaprogramming features to Java in order to increase its runtime adaptiveness, while taking advantage of the robustness of its static type system and the performance of its virtual machine. We support the dynamic addition, deletion and replacement of class methods and fields, and dynamic code generation. The metaprogramming services are provided as a library, so neither the Java language nor its virtual machine are modified. We evaluate our system, called JMPLib, and compare it with the existing metaprogramming systems for the Java platform and other highly optimized dynamic languages. JMPLib obtains similar runtime performance to the existing fastest system that modifies the implementation of the Java virtual machine. Moreover, our system introduces no performance penalty when metaprogramming is not used, and consumes fewer memory resources than the rest of implementations for the Java platform.

Transparent replication using metaprogramming in Cyan

SCIENCE OF COMPUTER PROGRAMMING 2020年 200卷 102531-102531页

Replication can be used to increase the availability of a service by creating many operational copies of its data called replicas. Active replication is a form of replication that has strong consistency semantics, which are easier to reason about and program. However, creating replicated services using active replication still demands from the programmer the knowledge of subtleties of the replication mechanism. In this paper we show how to use the metaprogramming infrastructure of the Cyan language to shield the application programmer from these details, allowing easier creation of fault-tolerant replicated applications through simple annotations.
