“…V2I instead employs strings and string templates. A high-fidelity parse tree representation [31,32] can provide the ability to easily rewrite source while retaining much of the original source code comments and indentation. For scripting refactorings, we can assume that such high fidelity is an important, but nevertheless secondary concern.…”

To facilitate experimentation with creating new, complex refactorings, we want to reuse existing transformation and analysis code as orchestrated parts of a larger refactoring: i.e., to script refactorings. The language we use to perform this scripting must be able to deal with the diversity of languages, tools, analyses, and transformations that arise in practice. To illustrate one solution to this problem, in this paper we describe, in detail, a specific refactoring script for switching from the Visitor design pattern to the Interpreter design pattern. This script, written in the meta-programming language Rascal, and targeting an interpreter written in Java, extracts facts from the interpreter code using the Eclipse JDT, performs the needed analysis in Rascal, and then transforms the interpreter code using a combination of Rascal code and existing JDT refactorings. Using this script we illustrate how a new, real and complex refactoring can be scripted in a few hundred lines of code and within a short timeframe. We believe the key to successfully building such refactorings is the ability to pair existing tools, focused on specific languages, with general-purpose meta-programming languages.

“…The Proteus system [16] addresses similar problems of performing transformations on large C++ systems while preserving the layout and handling code before preprocessing. Other approaches include JavaML [1] and others using an intermediate language to describe the source, as in the case of the C Intermediate Language (CIL) [13].…”

Abstract-srcML is an XML representation for C/C++/Java source code that forms a platform for the efficient exploration, analysis, and manipulation of large software projects. The lightweight format allows for round-trip transformation from source to srcML and back to source with no loss of information or formatting. The srcML toolkit consists of the src2srcml tool for robust translation to the srcML format and the srcml2src tool for querying via XPath, and transformation via XSLT. In this demonstration a guide of these features is provided along with the use of XPath for constructing source-code queries and XSLT for conducting simple transformations.

“…SDF has been used to define various composite languages, often based on mainstream languages such as C/C++ [Waddington and Yao 2007], PHP [Bravenboer et al 2007], and Java [Bravenboer and Visser 2004;Kats et al 2008]. The example grammar shown in Figure 3 extends Java with embedded SQL queries.…”

Integrated development environments (IDEs) increase programmer productivity, providing rapid, interactive feedback based on the syntax and semantics of a language. Unlike conventional parsing algorithms, scannerless generalized-LR parsing supports the full set of context-free grammars, which is closed under composition, and hence can parse languages composed from separate grammar modules. To apply this algorithm in an interactive environment, this paper introduces a novel error recovery mechanism. Our approach is language-independent, and relies on automatic derivation of recovery rules from grammars. By taking layout information into consideration it can efficiently suggest natural recovery suggestions.
