A Lazy Desugaring System for Evaluating Programs with Sugars
Extending a programming language with syntactic sugars is common practice in language design. Given a core language, one can define a surface language on top of it with sugars. We propose a lazy desugaring sys...

An Efficient Composition of Bidirectional Programs by Memoization and Lazy Update
Bidirectional transformations (BX) are a solution to the view update problem and widely used for synchronizing data. The semantics and correctness of bidirectional programs have been investigated intensively d...

A Counterexample-Guided Debugger for Non-recursive Datalog
The Datalog language is used in many potential applications including database queries, program analysis, bidirectional transformations, and so forth. In practice, such a Datalog program is expected to be well...

Marker-Directed Optimization of UnCAL Graph Transformations
Buneman et al. proposed a graph algebra called UnCAL (Unstructured CALculus) for compositional graph transformations based on structural recursion, and we have recently applied to model transformations. The co...

Generate, Test, and Aggregate
MapReduce, being inspired by the map and reduce primitives available in many functional languages, is the de facto standard for large scale data-intensive parallel programming. Although it has succeeded in pop...

Toward Bidirectionalization of ATL with GRoundTram
ATL is a language for describing model transformations currently in uni-direction. In our previous work we have shown that transformations of graph structures given in some form can be bidirectionalized and ha...

Program Calculation in Coq
Program calculation, being a programming technique that derives programs from specification by means of formula manipulation, is a challenging activity. It requires human insights and creativity, and needs sys...

Context-Preserving XQuery Fusion
XQuery is a DBPL for querying XML databases. The semantics of XQuery is context sensitive and requires preservation of document order. In this paper, we propose, as far as we are aware, the first XQuery fusion...

Gradual Refinement
Pattern matching is advantageous for understanding and reasoning about function definitions, but it tends to tightly couple the interface and implementation of a datatype. Significant effort has been invested ...

A Grammar-Based Approach to Invertible Programs
Program inversion has many applications such as in the implementation of serialization/deserialization and in providing support for redo/undo, and has been studied by many researchers. However, little attentio...

An Efficient Staging Algorithm for Binding-Time Analysis
Binding-Time Analysis (BTA) is one of the compile-time program analyses which is a general framework for program optimization and program generation [1]. The task of BTA is to divide a source program into two ...

PType System: A Featherweight Parallelizability Detector
Parallel programming is becoming an important cornerstone of general computing. In addition, type systems have significant impact on program analysis. In this paper, we demonstrate an automated type-based syst...

An Algebraic Approach to Bi-directional Updating
In many occasions would one encounter the task of maintaining the consistency of two pieces of structured data that are related by some transform — synchronising bookmarks in different web browsers, the source...

Deterministic Higher-Order Patterns for Program Transformation
Higher-order patterns, together with higher-order matching, enable concise specification of program transformation, and have been implemented in several program transformation systems. However,higher-order mat...

An Accumulative Parallel Skeleton for All
Parallel skeletons intend to encourage programmers to build a parallel program from ready-made components for which efficient implementations are known to exist, making the parallelization process simpler. How...

Generation of Efficient Programs for Solving Maximum Multi-marking Problems
Program generation has seen an important role in a wide range of software development processes, where effective calculation rules are critical. In this paper, we propose a more general calculation rule for ge...

Deriving Parallel Codes via Invariants
Systematic parallelization of sequential programs remains a major challenge in parallel computing. Traditional approaches using program schemes tend to be narrower in scope, as the properties which enable para...
