Software Visualisation and Comparison Tool - SVCT

http://www.csn.ul.ie/~mrmen/fyp.html

Final Year Project of:

Shane Lillis, 9514147

4th Year Computer Engineering

Supervisor: Mr. Tom Newe

Final Demonstration : 28/4/1999

Project Goals and Motivation

Develop a lecturers tool which can be used to visualise and compare source code files

- used to aid lecturer to identify copied assignments handed in by students

The Visualisation and Comparison

Program (Code) Visualisation

- colouring of the source code text according to the control constructs that exist in the code

- reducing the text to pixel form - ‘Zooming’

Comparison through Visualisation

Boundary Analysis Comparison

SVCT Tool

Bench Demonstration

Some Designs

OMT : The Object Model (with associations)

OMT : Dynamic Models (using the event trace technique)

- Visualising the Source Code Text

- Reducing the textual code to the DIB

- Comparison of 2 files

The Tokenizer algorithm

The FileInformationArray - use and construction

OMT: The Object Model

CFIA = FileInformationArray Class

OMT: The Object Model

The CTempararyComparisonArray class has the same design as the CLinkedListOfFIAs class. Therefore, this is a possible candidate for code reuse.

In the implementation, the CTokenizer class is broken down as follows:

Also, in the implementation, the CBitmap class is known as CDib (Device Independent Bitmap).

SVCT Installation Files

The files installed are as follows

- SVCT.exe

- readme.txt

- mfc42d.dll

- msvcrtd.dll

- mfco42d.dll

These are installed using install.bat - see project website for

download of these files.

The website is a repository for documents, application and source

code employed in the project.
