Simplifying the Construction of Interactive Programs in a Functional Programming Environment
Eric B. Blough
Computer Science PhD Candidate

Functional programming offers numerous benefits to the programmer, including higher-order functions, absence of control flow, automatic storage management, and static type inference and type checking. The writing of interactive programs has been a long-standing challenge to the functional programming community, since the statefulness of input and output does not merge smoothly with the statelessness of a pure functional language. Historic and recent approaches to interactivity clearly demonstrate the utility of functional programming of interactive systems, but these approaches are cognitively problematic.

Spreadsheets offer numerous, but largely different, benefits for certain classes of programming problems. These benefits include visible, manipulable data representations, automatic consistency maintenance, absence of control flow, and immediate feedback. Although the spreadsheet environment provides significant interactive power, it is limited and minimally customizable, and has cognitive weaknesses of its own.

We present Esquisse, an alternative to both of these approaches that shares much with each. Esquisse combines the full power of a functional programming language with an extensible spreadsheet-inspired environment made of pure functional components. Esquisse demonstrates that powerful interactive programs can be produced quickly with relatively low cognitive cost, and suggests a promising direction for future research in functional programming environments.
