The Cornell Program Synthesizer demands a structural perspective at all stages of program development and its separate features are unified by a common foundation: a grammar for the programming language.
Abstract
Programs are not text; they are hierarchical compositions of computational structures and should be edited, executed, and debugged in an environment that consistently acknowledges and reinforces this viewpoint. The Cornell Program Synthesizer demands a structural perspective at all stages of program development. Its separate features are unified by a common foundation: a grammar for the programming language. Its full-screen derivation-tree editor and syntax-directed diagnostic interpreter combine to make the Synthesizer a powerful and responsive interactive programming tool.

Hazelnut: a bidirectionally typed structure editor calculus

TL;DR: Hazelnut is introduced, a structure editor based on a small bidirectionally typed lambda calculus extended with holes and a cursor that serves as a foundational account of typed structure editing, and how its semantics lends itself to implementation as an event-based functional reactive program.

Token-based computer program editor with program comment management

TL;DR: A user-friendly text editor for structurally represented computer programs is presented in this article, which combines advantages of text editors and structure editors by transforming, as the user types, the text stream entered by the user into a token stream, where the tokens of the token stream constitute the words of the program being entered.

Continuous execution: the VisiProg environment

TL;DR: This paper envision an even more dynamic environment in which the functionality of a network of programs, an individual program, or a program segment can be viewed “continuously” with editing changes to either the program input or program body.

Per-keystroke incremental lexing using a conventional batch lexer

TL;DR: In this article, a batch lexer is used to incrementally update a token stream representation of a computer program maintained in an editor as the computer program is being edited, and a keystroke executive interprets editing inputs and dispatches editing events to a lexical analyzer.

Extended programming in the large in a software development environment

TL;DR: The main concern of this paper is to show how an incremental and integrated tool set, regarding the consistency of software documents can support software development.

Closest-point problems

TL;DR: The purpose of this paper is to introduce a single geometric structure, called the Voronoi diagram, which can be constructed rapidly and contains all of the relevant proximity information in only linear space, and is used to obtain O(N log N) algorithms for most of the problems considered.

Geometric intersection problems

TL;DR: An O(N log N) algorithm is given to determine whether any two intersect and use it to detect whether two simple plane polygons intersect and to show that the Simplex method is not optimal.

An Optimal Worst Case Algorithm for Reporting Intersections of Rectangles

TL;DR: This paper investigates the problem of reporting all intersecting pairs in a set of n rectilinearly oriented rectangles in the plane and describes an algorithm that solves this problem in worst case time proportional to n lg n + k, where k is the number of interesecting pairs found.
