A Process Algebra Software Engineering Environment

In previous work we described how the process algebra based language PSF can be used in software engineering, using the ToolBus, a coordination architecture also based on process algebra, as implementation model. In this article we summarize that work and describe the software development process more formally by presenting the tools we use in this process in a CASE setting, leading to the PSF-ToolBus software engineering environment. We generalize the refine step in this environment towards a process algebra based software engineering workbench of which several instances can be combined to form an environment

Software (Re-)Engineering with PSF III: an IDE for PSF

We describe the design of an integrated development environment (IDE) for PSF. In the software engineering process we used process algebra in the form of PSF for the specification of the architecture of the IDE. This specification is refined to a PSF specification of the IDE system as a ToolBus application, by applying vertical and horizontal implementation techniques. We implemented the various tools as specified and connected them with a ToolBus script extracted from the system specification

Software (Re-)Engineering with PSF II: from architecture to implementation

This paper presents ongoing research on the application of PSF in the field of software engineering and reengineering. We build a new implementation for the simulator of the PSF Toolkit starting from the specification in PSF of the architecture of a simple simulator and extend it with features to obtain the architecture of a full simulator. We apply refining and constraining techniques on the specification of the architecture to obtain a specification low enough to build an implementation from

My favorite editor anywhere

How can off-the-shelf editors be reused in applications that need mature editing support? We describe our editor multiplexer which enables interactive, application guided editing sessions using e.g. GNU Emacs and Vim. At a cost of less than 1 KLOC of editor specific glue code, both IDE builders and users benefit. Rapid integration of existing editors reduces application development cost, and users are not confronted with yet another foreign editor with its own learning curv
