  • Haskell-Like S-Expression-Based Language Designed for an IDE
    Department of Computing Imperial College London MEng Individual Project Haskell-Like S-Expression-Based Language Designed for an IDE Author: Supervisor: Michal Srb Prof. Susan Eisenbach June 2015 Abstract The state of the programmers’ toolbox is abysmal. Although substantial effort is put into the development of powerful integrated development environments (IDEs), their features often lack capabilities desired by programmers and target primarily classical object oriented languages. This report documents the results of designing a modern programming language with its IDE in mind. We introduce a new statically typed functional language with strong metaprogramming capabilities, targeting JavaScript, the most popular runtime of today; and its accompanying browser-based IDE. We demonstrate the advantages resulting from designing both the language and its IDE at the same time and evaluate the resulting environment by employing it to solve a variety of nontrivial programming tasks. Our results demonstrate that programmers can greatly benefit from the combined application of modern approaches to programming tools. I would like to express my sincere gratitude to Susan, Sophia and Tristan for their invaluable feedback on this project, my family, my parents Michal and Jana and my grandmothers Hana and Jaroslava for supporting me throughout my studies, and to all my friends, especially to Harry whom I met at the interview day and seem to not be able to get rid of ever since. ii Contents Abstract i Contents iii 1 Introduction 1 1.1 Objectives ........................................ 2 1.2 Challenges ........................................ 3 1.3 Contributions ...................................... 4 2 State of the Art 6 2.1 Languages ........................................ 6 2.1.1 Haskell ....................................

  • The Logic of Demand in Haskell
    Under consideration for publication in J. Functional Programming 1 The Logic of Demand in Haskell WILLIAM L. HARRISON Department of Computer Science University of Missouri Columbia, Missouri RICHARD B. KIEBURTZ Pacific Software Research Center OGI School of Science & Engineering Oregon Health & Science University Abstract Haskell is a functional programming language whose evaluation is lazy by default. However, Haskell also provides pattern matching facilities which add a modicum of eagerness to its otherwise lazy default evaluation. This mixed or “non-strict” semantics can be quite difficult to reason with. This paper introduces a programming logic, P-logic, which neatly formalizes the mixed evaluation in Haskell pattern-matching as a logic, thereby simplifying the task of specifying and verifying Haskell programs. In P-logic, aspects of demand are reflected or represented within both the predicate language and its model theory, allowing for expressive and comprehensible program verification. 1 Introduction Although Haskell is known as a lazy functional language because of its default eval- uation strategy, it contains a number of language constructs that force exceptions to that strategy. Among these features are pattern-matching, data type strictness annotations and the seq primitive. The semantics of pattern-matching are further enriched by irrefutable pattern annotations, which may be embedded within pat- terns. The interaction between Haskell’s default lazy evaluation and its pattern- matching is surprisingly complicated. Although it offers the programmer a facility for fine control of demand (Harrison et al., 2002), it is perhaps the aspect of the Haskell language least well understood by its community of users. In this paper, we characterize the control of demand first in a denotational semantics and then in a verification logic called “P-logic”.

  • Functional Baby Talk: Analysis of Code Fragments from Novice Haskell Programmers
    Functional Baby Talk: Analysis of Code Fragments from Novice Haskell Programmers Jeremy Singer and Blair Archibald School of Computing Science University of Glasgow UK [email protected] [email protected] What kinds of mistakes are made by novice Haskell developers, as they learn about functional pro- gramming? Is it possible to analyze these errors in order to improve the pedagogy of Haskell? In 2016, we delivered a massive open online course which featured an interactive code evaluation en- vironment. We captured and analyzed 161K interactions from learners. We report typical novice developer behavior; for instance, the mean time spent on an interactive tutorial is around eight min- utes. Although our environment was restricted, we gain some understanding of Haskell novice er- rors. Parenthesis mismatches, lexical scoping errors and do block misunderstandings are common. Finally, we make recommendations about how such beginner code evaluation environments might be enhanced. 1 Introduction The Haskell programming language [14] has acquired a reputation for being difficult to learn. In his presentation on the origins of Haskell [23] Peyton Jones notes that, according to various programming language popularity metrics, Haskell is much more frequently discussed than it is used for software implementation. The xkcd comic series features a sarcastic strip on Haskell’s side-effect free property [21]. Haskell code is free from side-effects ‘because no-one will ever run it.’ In 2016, we ran the first instance of a massive open online course (MOOC) at Glasgow, providing an introduction to functional programming in Haskell. We received many items of learner feedback that indicated difficulty in learning Haskell.

  • Haskell As a Higher Order Structural Hardware Description Language
    Haskell as a higher order structural hardware description language Master's thesis by Matthijs Kooijman December 9, 2009 Committee: Dr. Ir. Jan Kuper Ir. Marco Gerards Ir. Bert Molenkamp Dr. Ir. Sabih Gerez Computer Architecture for Embedded Systems Faculty of EEMCS University of Twente Abstract Functional hardware description languages have been around for a while, but never saw adoption on a large scale. Even though advanced features like higher order functions and polymorphism could enable very natural parametrization of hardware descriptions, the conventional hardware description languages VHDL and Verilog are still most widely used. Cλash is a new functional hardware description language using Haskell's syntax and semantics. It allows structurally describing synchronous hardware, using normal Haskell syntax combined with a selection of built-in functions for operations like addition or list operations. More complex constructions like higher order functions and polymorphism are fully supported. Cλash supports stateful descriptions through explicit descriptions of a function's state. Every function accepts an argument containing its current state and returns its updated state as a part of its result. This means every function is called exactly once for each cycle, limiting Cλash to synchronous systems with a single clock domain. A prototype compiler for Cλash has been implemented that can generate an equivalent VHDL description (using mostly structural VHDL). The prototype uses the front-end (parser, type-checker, desugarer) ofthe existing GHC Haskell compiler. This front-end generates a Core version of the description, which is a very small typed functional language. A normalizing system of transformations brings this Core version into a normal form that has any complex parts (higher order functions, polymorphism, complex nested structures) removed.

  • A Proxima-Based Haskell IDE
    Thesis for the degree of Master of Science A Proxima-based Haskell IDE Gerbo Engels October 2008 INF/SCR-07-93 Supervisor: Center for Software Technology prof. dr. S. Doaitse Swierstra Dept. of Information and Computing Sciences Universiteit Utrecht Daily supervisor: Utrecht, The Netherlands dr. Martijn M. Schrage Abstract Proxima is a generic presentation-oriented editor for structured documents, in which a graphical presentation of the document can be edited directly (WYSIWYG editing), resulting in changes in the underlying structure of the document. Proxima understands the document structure and it supports direct edit operations on the document structure as well. A Proxima instantiation uses a parser to get the document structure; modern compilers have parsers as well, which may be accessible through an API. Using the parser of an external compiler as the Proxima parser saves one from writing a new parser. Furthermore, the parse tree of a com- piler can contain extra information that is useful to display in an editor, such as type information of a Haskell compiler in a Haskell source code editor. This thesis aims to use the parser of an external compiler as the Proxima parser. We identify and solve problems that arise when using the parser of an external compiler as the Proxima parser, and two Haskell editors are developed as Proxima instantiations that use the parser of GHC or EHC respectively. i ii Contents 1 Introduction 1 1.1 Thesis Overview.........................................2 I The State of the World3 2 Existing Haskell Editors and IDE’s5 2.1 Visual Haskell...........................................6 2.2 Eclipse Plug-in...........................................7 2.3 Haskell Editors Written in Haskell...............................8 2.4 Other Editors or Tools.....................................

  • Trace-Based Just-In-Time Compilation for Lazy Functional Programming Languages
    Trace-based Just-in-time Compilation for Lazy Functional Programming Languages Thomas Schilling School of Computing University of Kent at Canterbury A thesis submitted for the degree of Doctor of Philosophy April 2013 i Abstract This thesis investigates the viability of trace-based just-in-time (JIT) compilation for optimising programs written in the lazy functional programming language Haskell. A trace-based JIT compiler optimises only execution paths through the program, which is in contrast to method-based compilers that optimise complete functions at a time. The potential advantages of this approach are shorter compilation times and more natural interprocedural optimisation. Trace-based JIT compilers have previously been used successfully to optimise programs written in dynamically typed languages such as JavaScript, Python, or Lua, but also statically typed languages like Java or the Common Language Runtime (CLR). Lazy evalu- ation poses implementation challenges similar to those of dynamic languages, so trace-based JIT compilation promises to be a viable ap- proach. In this thesis we focus on program performance, but having a JIT compiler available can simplify the implementation of features like runtime inspection and mobile code. We implemented Lambdachine, a trace-based JIT compiler which im- plements most of the pure subset of Haskell. We evaluate Lamb- dachine's performance using a set of micro-benchmarks and a set of larger benchmarks from the \spectral" category of the Nofib bench- mark suite. Lambdachine's performance (excluding garbage collection overheads) is generally about 10 to 20 percent slower than GHC on statically optimised code. We identify the two main causes for this slow-down: trace selection and impeded heap allocation optimisations due to unnecessary thunk updates.

  • Introduction to Haskell
    Advanced Topics in Programming Languages Lecture 2 - Introduction to Haskell Ori Bar El Maxim Finkel 01/11/17 1 History Haskell is a lazy, committee designed, pure functional programming language that started development in the late 1980’s. Haskell derives its name from Haskell Curry, a mathematician and logician. The goals of the Haskell language were formally defined by its designers, and they stated that Haskell should: 1. Be suitable for teaching, research, and applications, including building 2. Be completely described via the publication of a formal syntax and se- mantics. 3. Be freely available. 4. Be usable as a basis for further language research. 5. Be based on ideas that enjoy a wide consensus. 6. Reduce unnecessary diversity in functional programming languages. Development of the language began shortly after the 1988 meeting, but it was not until April 1, 1990 that the first working version of Haskell, Haskell 1.0, was released. From 1990 to 1999 many incremental versions of Haskell were released and in 1999 the Haskell Committee decided that a formalized and stable version of the language needed to be released. They decided to call this standard version of the language Haskell 98. The reasoning behind creating a Haskell standard was so the language could be used in teaching environments and books could be written about it. Haskell 98 did not fully stabilize until 2002. Haskell recently released a new standardized version called Haskell 2010. This update includes all the changes in the language since 2002 repackaged with up-to-date documentation in the newest version of the Haskell Report.

  • Ready, Set, Verify! Applying Hs-To-Coq to Real-World Haskell Code
    Ready, Set, Verify! Applying hs-to-coq to real-world Haskell code JOACHIM BREITNER, University of Pennsylvania, USA ANTAL SPECTOR-ZABUSKY, University of Pennsylvania, USA YAO LI, University of Pennsylvania, USA CHRISTINE RIZKALLAH, University of New South Wales, Australia JOHN WIEGLEY, BAE Systems, USA STEPHANIE WEIRICH, University of Pennsylvania, USA Good tools can bring mechanical verification to programs written in mainstream functional languages. Weuse hs-to-coq to translate significant portions of Haskell’s containers library into Coq, and verify it against specifications that we derive from a variety of sources including type class laws, the library’s testsuite,and interfaces from Coq’s standard library. Our work shows that it is feasible to verify mature, widely-used, highly optimized, and unmodified Haskell code. We also learn more about the theory of weight-balanced trees, extend hs-to-coq to handle partiality, and – since we found no bugs – attest to the superb quality of well-tested functional code. CCS Concepts: • Software and its engineering → Software verification; Additional Key Words and Phrases: Coq, Haskell, verification 1 INTRODUCTION What would it take to tempt functional programmers to verify their code? Certainly, better tools would help. We see that functional programmers who use dependently- typed languages or proof assistants, such as Coq [The Coq development team 2016], Agda [Bove et al. 2009], Idris [Brady 2017], and Isabelle [Nipkow et al. 2002], do verify their code, since their tools allow it. However, adopting these platforms means rewriting everything from scratch. What about the verification of existing code, such as libraries written in mature languages like Haskell? Haskell programmers can reach for LiquidHaskell [Vazou et al.
