Alembicue: a Projectional Editor & IDE for Container Application Architecture Computer Science 18COC251 B627091 Alembicue: A projectional editor & IDE for container application architecture George Garside Supervisor: Dr. Daniel Reidenbach Loughborough University Summer 2019 Abstract The lack of a competent integrated development environment for Docker is a detriment to the field of containerisation and cloud computing. This project documents the development of Alembicue, a projectional and productive Docker IDE, implementing a more formally specified language definition, representative of what is necessary to create imagesfor use with a containerisation platform. Alembicue guarantees syntactic correctness with a projectional editor mutating an abstract syntax tree, incorporating contextual intentions and quick fixes to suggest and automatically apply standards and best practices. Alembicue’s launch has been a success, being received well by the community with tens of thousands of interested visitors to the project page, and elated testimonials from those having used the application and the innovative concepts portrayed within. Acknowledgements I would like to thank my supervisor, Dr. Daniel Reidenbach, for his consistent support and valuable feedback on my work. I would also like to thank my family and friends for their support in my studies. ii alembicate, v. 1627. transitive.

  • The Evolution of Lisp

Gabriel Thinking Machines Corporation Lucid, Inc. 245 First Street 707 Laurel Street Cambridge, Massachusetts 02142 Menlo Park, California 94025 Phone: (617) 234-2860 Phone: (415) 329-8400 FAX: (617) 243-4444 FAX: (415) 329-8480 E-mail: [email protected] E-mail: [email protected] Abstract Lisp is the world’s greatest programming language—or so its proponents think. The structure of Lisp makes it easy to extend the language or even to implement entirely new dialects without starting from scratch. Overall, the evolution of Lisp has been guided more by institutional rivalry, one-upsmanship, and the glee born of technical cleverness that is characteristic of the “hacker culture” than by sober assessments of technical requirements. Nevertheless this process has eventually produced both an industrial- strength programming language, messy but powerful, and a technically pure dialect, small but powerful, that is suitable for use by programming-language theoreticians. We pick up where McCarthy’s paper in the first HOPL conference left off. We trace the development chronologically from the era of the PDP-6, through the heyday of Interlisp and MacLisp, past the ascension and decline of special purpose Lisp machines, to the present era of standardization activities. We then examine the technical evolution of a few representative language features, including both some notable successes and some notable failures, that illuminate design issues that distinguish Lisp from other programming languages. We also discuss the use of Lisp as a laboratory for designing other programming languages. We conclude with some reflections on the forces that have driven the evolution of Lisp.

The Mjølner BETA System is a result of the Scandinavian research project Mjølner. The integration of the various tools in the Mjølner BETA System is es- tablished by insisting that all tools in the system utilizes one single represen- tation of the program. This representation is abstract syntax trees (ASTs). All manipulations of the ASTs by the various tools are done, utilizing the metaprogramming system, which defines an interface to the AST, and ways to manipulate the AST. The Mjølner BETA System includes an implementation of the BETA programming language. In addition it includes a set of grammar-based tools, which can be used for any formal language that is defined by a context- free grammar. The grammar-based tools include a hyper structure editor, a metaprogramming system, and a fragment system.

    Tiny Structure Editors for Low, Low Prices! (Generating GUIs from toString Functions) Brian Hempel Ravi Chugh University of Chicago University of Chicago brianhempel@ uchicago.edu rchugh@ uchicago.edu Abstract—Writing toString functions to display custom data values is straightforward, but building custom interfaces to manipulate such values is more difficult.

Box 4079, 1009 AB Amsterdam, The Netherlands Email: [email protected], [email protected], [email protected] Abstract ABC is an interactive programming language where both ease of learning and ease of use stood high amongst its principle design aims. The language is embedded in a dedicated environment that includes a structure-based editor. To fit in with the design aims, the editor had to be easy to learn, demanding a small command set, and easy to use, demanding a powerful command set and strong support for the user in composing programs, without enforcing a computer- science understanding of issues of syntax and the like. Some novel design rules have led to an interesting editor, where the user may enter and edit text either structurally or non-structurally, without having to use different “modes”. 1991 Mathematics Subject Classification: 68N15, 68Q50. 1991 CR Categories: D19, D.2.2, D.2.6, H.1.2, H.5.2.

  • Structure Editors – Old Hat Or Future Vision?
    Structure Editors – Old Hat or Future Vision? Andreas Gomolka, Bernhard Humm Hochschule Darmstadt – University of Applied Sciences, Haardtring 100, 64295 Darmstadt, Germany [email protected], [email protected] Abstract. Structure editors emphasise a natural representation of the underlying tree structure of a program, often using a clearly identifiable 1-to-1 mapping between syntax tree elements and on-screen artefacts. This paper presents layout and behaviour principles for structure editors and a new structure editor for Lisp. The evaluation of the editor‟s usability reveals an interesting mismatch. Whereas by far most participants of a questionnaire intuitively favour the structure editor to the textual editor, objective improvements are measurable, yet not significant. Keywords: Programming, structure editor, evaluation, Lisp, Eclipse 1 Introduction Structure editors have fascinated designers of development environments for decades [1, 2, 3, 4]. The idea is simple and convincing. The elements of the syntax tree of a program are mapped to on-screen artefacts and can be edited directly. The basis for this is the awareness that programs are more than just text [5]. A programmer designing a piece of code thinks in structures: classes, methods, blocks, loops, conditions, etc. Using a textual program editor he or she has to codify those syntactically using parentheses such as „{...}‟, „(...)‟, „[...]‟ or using keywords such as „begin ... end‟. The compiler then parses the syntactic elements and re-creates the structures in the form of an abstract or concrete syntax tree – the same structures which the programmer originally had in mind. This just seems inefficient and not intuitive. Structure editors fill this gap: What the programmer thinks is what he or she sees in the editor.

  • An Interactive Programming System for Pascal
    BIT 20 (1980), 163- 174 AN INTERACTIVE PROGRAMMING SYSTEM FOR PASCAL JERKER WILANDER Abstract. Interactive program development tools are being increasingly recognized as helpful in the construction of programs. This paper describes an integrated incremental program development system for Pascal called Pathcal. Pathcal contains facilities for creation, editing, debugging and testing of procedures and programs. The system facilities are all Pascal procedures or variables and because of this allows the programmer to program the system in itself. Keywords: Incremental programming, programming systems, debugging, Pascal. Introduction. Program development is today commonly supported by an interactive time- sharing system. A more advanced type of interactive program development tool is an incremental system- The basic programming cycle in an incremental system is not the execution of a program but rather a statement or a declaration. This property together with the ever present "database" of values and declarations constitutes an incremental system. The incremental system is the foundation of the next generation of programming support, the "programming environment". A programming environment contains all the tools in one integrated system and it should support the terminal by e.g. allowing editingof incorrect statements. It should provide the facilities that the operating system monitor usually provides, to allow programmability of all facilities. In a sense the programming environment could be viewed as a programming language oriented monitor which is incrementally extensible. The most important example of this kind of system is INTERLISP [13, but APL [2] has also gone a long way in this direction. For a more conventional looking language, EL1, the ECL system [3,4] could be mentioned.
