Dms Software Reengineering Toolkit Software For DMS

The term software for DMS is very broad and covers any formal notation, including programming languages, markup languages, hardware description languages, design notations, data descriptions, and domain-specific languages.

This toolkit is the first step towards the implementation of the Design Maintenance System.

An ambitious vision of a 21st Century software engineering environment that supports the incremental construction and maintenance of large application systems, driven by semantics and captured designs.

A software engineering environment that supports the incremental engineering and maintenance of large application systems, driven by domain knowledge, semantics, captured designs and automation.

DMS records: what the software is supposed to do (specification).

Using practical program generation and transformation technology, DMS will enable designers to.

Domain-specific program generation Factory Control synthesis Entity-Relationship compilers.

DMS is designed for large scale software systems Fast parsing and transformation engines (procedures, trees, graphs).

Implemented in Semantic Designs parallel programming language, PARLANSE.

A very simple model of DMS is that of an extremely generalized compiler, having a parser, a semantic analyzer, a program transformation engine (to do code generation and optimization), and final output formatting components.

It is particularly important that the analyzer output can be used to choose the desired transforms.

Unlike a conventional compiler, in which each component is specific to its task of translating one source language to one target machine language, each DMS component is highly parameterized, enabling a stunningly wide variety of effects.

This means one can change the input language, change the analysis, change the transforms, and change the output in arbitrary ways.

Also, unlike a conventional compiler, DMS can process thousands of files from multiple languages at the same moment, allowing analyses andor consistent code changes across complex systems of files.

Full UNICODE-based parser and lexer generation with automatic error recovery.

The parser technology is based on GLR, and can handle any context-free language, even with ambiguities (much stronger than YACCLALR).

Semantic Design believes that is has more language front ends than any other organization on Earth.

In fidelity-printing mode, comments, spacing and lexical formatting information of unchanged code is preserved.

Customizing allows generation of source code in obfuscated source text.

A source code obfuscator accepts a program source file, and generates another functionally equivalent source file which is much harder to understand or reverse-engineer.

Semantic Designs Obfuscation tools generally strip comments, remove nice indentation and whitespace, encode constants in inconveniently readable ways, and rename identifiers in source (for variables, functions, etc.) from their original name to nonsense names that convey no information.

This is useful for technical protection of intellectual property.
