We explore a simple approach to incorporating new language features into a functional language. New features are realized simply by redeening the meanings of primitive functions. That is, the programming language is not modiied at all; rather, new features are just programmed within the existing language. Surprisingly, in a combinator-based functional language the class of language features tha...

Context: This paper presents the concept of open programming language interpreters, a model to support them and a prototype implementation in the Neverlang framework for modular development of programming languages. Inquiry: We address the problem of dynamic interpreter adaptation to tailor the interpreter’s behaviour on the task to be solved and to introduce new features to fulfil unforeseen r...

This paper presents a relatively simple visual notation for meta-programming that spans multiple levels of abstraction. Two-dimensional data flow provides readable representations of meta-programs that expose potential parallelism. This work suggests visual notations for data structures, data flows, pattern matching, conditionals, iteration and synchronization. The framework provides encapsulat...

In this paper we consider a family of languages (USWIM) which is based on Landin’s ISWIM (the individual languages being determined by appropriate continuous algebras of data objects and operations on these objects). We give a simple mathematical semantics for USWIM, and also give a system of program manipulation rules and a system of inference rules for reasoning about USWIM programs, the latt...

Traditional programming language design approaches center around theoretical and performance-oriented evaluation. Recently, researchers have been considering more approaches to language design, including the use of quantitative and qualitative user studies to evaluate how different designs affect users. In this paper, we argue for an interdisciplinary approach that incorporates many different m...

Influenced J,[1] K,[2] Mathematica, MATLAB,[3] Nial,[4] PPL, Q APL (named after the book A Programming Language)[5] is an interactive array-oriented language and integrated development environment which is available from a number of commercial and non-commercial vendors[6] and for most computer platforms.[7] It is based on a mathematical notation developed by Kenneth E. Iverson. APL has a combi...

More and more programming tools have been created to help people to learn new programming languages. Although the number of tools to support beginning learners has increased, none directly compare different languages. This paper proposes a translation-based programming learning method that supports programming language learning for beginners of a new language who are familiar with a different l...

First, a short introduction to inductive logic programming and machine learning is presented and then an inductive database mining query language RDM (Relational Database Mining language). RDM integrates concepts from inductive logic programming, constraint logic programming, deductive databases and meta-programming into a flexible environment for relational knowledge discovery in databases. Th...
