PCG: A prototype incremental compilation facility for the SAGA environment, appendix F

A programming environment supports the activity of developing and maintaining software. New environments provide language-oriented tools such as syntax-directed editors, whose usefulness is enhanced because they embody language-specific knowledge. When syntactic and semantic analysis occur early in the cycle of program production, that is, during editing, the use of a standard compiler is inefficient, for it must re-analyze the program before generating code. Likewise, it is inefficient to recompile an entire file, when the editor can determine that only portions of it need updating. The pcg, or Pascal code generation, facility described here generates code directly from the syntax trees produced by the SAGA syntax directed Pascal editor. By preserving the intermediate code used in the previous compilation, it can limit recompilation to the routines actually modified by editing

SAGA: A project to automate the management of software production systems

The SAGA system is a software environment that is designed to support most of the software development activities that occur in a software lifecycle. The system can be configured to support specific software development applications using given programming languages, tools, and methodologies. Meta-tools are provided to ease configuration. The SAGA system consists of a small number of software components that are adapted by the meta-tools into specific tools for use in the software development application. The modules are design so that the meta-tools can construct an environment which is both integrated and flexible. The SAGA project is documented in several papers which are presented

Databases for Software Engineering Environments - The Goal has not yet been attained

We argue that, despite a substantial number of proposed and existing new database systems, a suitable database system for software development environments and especially process-centred environments does not yet exist. We do so by first reviewing and refining the requirements for such systems. We then review a number of available and archetypical database systems and show that they do not meet these requirements

SAGA: A project to automate the management of software production systems

The Software Automation, Generation and Administration (SAGA) project is investigating the design and construction of practical software engineering environments for developing and maintaining aerospace systems and applications software. The research includes the practical organization of the software lifecycle, configuration management, software requirements specifications, executable specifications, design methodologies, programming, verification, validation and testing, version control, maintenance, the reuse of software, software libraries, documentation, and automated management

Regular Right Part Grammars and Maintained and Constructor Attributes in Language Based Editors

116 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1987.This work concerns the generation of language specific editors which retain all text oriented editing commands. Our technique is to translate a language specification based on ambiguous regular right part grammars into an incremental LALR(1,1) parser. Strongly non-circular attribute grammars are adapted to regular right part grammars for static semantic processing. Finally, attribute grammars are extended with external data structures which improve the performance of the editor in some important instances and provide a framework for interaction between the attributed tree and the programming environment.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
