  • About the Edition

    This report provides a basis for evaluating relational programming by presenting an implementation of a moderately complex program using relational programming. The program is a syntax-directed editor, a major component in a programming environment that allows the direct construction, modification, and display (unparsing) of parse trees. Relational programming is ideal for this application, since the relational calculus provides a number of high-level operators for manipulating trees and other complex data structures. The editor is presented in two notations: the usual mathematical notation and a simple natural-language-like notation. (Author)

    Oslo is a project at Microsoft, of which various things have been heard but with little details until this week's PDC conference. What we have known is that it has something to do with ModelDrivenSoftwareDevelopment and DomainSpecificLanguages. A couple of weeks ago I got an early peek behind the curtain as I, and my language-geek colleague Rebecca Parsons, went through a . A syntax-directed editor is a tool for structured program development. Such an editor can enforce syntactic correctness incrementally by restricting editing operations to legitimate modifications of the program's context-free derivation tree. However, not all language features can be described by the context-free formalism.

The Synthesizer Generator is a generalization of our earlier system, the Cor­ nell Program Synthesizer [Teitelbaum81], which was a programming environ­ ment for a specific small dialect of PL/I.

It featured a display-oriented, syntax­ directed editor, an incremental compiler, an execution supervisor supporting source-level debugging, and a. A relational programming language (RPL) is a DeclarativeLanguagebuilt around the RelationalModelof data. StructuredQueryLanguage(SQL) is an example.

A relation can be viewed as a reversible function that can return an arbitrary number of values. For example, the "square root" relation maps the number to itself, but maps to [2 -2]. Unlike syntax-directed editors this editor does not use its tree structure to represent the parse tree of the program.

Instead the user is free to build any tree structure of text nodes he wants. Relational an educational tool to provide a workspace for experimenting with relational algebra, an offshoot of first-order logic.

It provides GUI that can be used for executing relational queries, and also a command line interface and a Python library. A syntax-directed editor may treat grammar rules as generative (e.g., offering the user templates that correspond to one or more steps in a formal derivation of program text) or proscriptive (e.g., preventing a phrase of a given part of speech from being moved to a context where another part of speech is required) or analytic (e.g., parsing.

In the program processing phase, programs in the language of the grammar are parsed and parse trees are built. Furthermore, our tables are suitable for generating syntax-directed editors which provide a full analytic mode. The efficiency of the analytic component of a syntax-directed editor obtained in this way and its easy integration with the generative component stress the advantages of incremental program writing.

Language has often been characterized as a systematic correlation between certain types of. Specifically, we derive two syntax-directed proof systems, U C and R C, for unary and relational cost analysis, by adding a cost monad to a (syntax-directed) logic of higher-order programs.

We study the metatheory of the systems, show that several nontrivial examples can be verified in them, and prove that existing frameworks for cost analysis. syntax of dates has changed could not be used any more because it is ambiguous (arithmetic operaton or date).

The SQL notation (date('')) is now used for the relational algebra mode. grid editor for inline relations; sql-dump import (beta) group editor; changed the basic structure of the editors (internally). Abstract. The intent of this position statement is to relate our experience with the actual use of a syntax directed editor (Mentor [5]) in different contexts: teaching, real software production, software maintenance and associated tasks, language design and development, development of programming tools and new programming structures.

Concepts and realization of a diagram editor generator based on hypergraph transformation. Diagram editors which are tailored to a specific diagram language typically support either syntax-directed editing or free-hand editing, i.e., the user is either restricted to a collection of predefined editing operations, or he is not restricted at all, but misses the convenience of such complex editing.
