Project Objectives Research the Software Visualisation area in

detail. Allow multiple source code files to be displayed

on screen in their analysed form. Allow the user to click on the analyzed files to

display the colour-enhanced source files. Show the files being compared side by side. Compare & highlight similar structures, variables

etc. in the source code files. Provide percentage similarity between files.

Other goals which are necessary for successful design and implementation are– Learning of the Software OO Methodology,

OMT– Learning of the MS Visual C++ 5 Language

with MFC’s

S.V. and O.M.T. Software Visualisation - the use of graphical

text manipulation to help understand the characteristics of programs– Program Visualisation

O.M.T. - Object Modeling Technique– Object Oriented Analysis & Design

Technique

– Iterative Lifecycle - focus is on analysis and data structures. Testing will be done upon completion of implementation.

Analysis

Design The 3 main design issues are

– source code analysis

– file comparison

– the GUI

Source Code Analysis : – The User selects the file to be analysed.– The Scanner reads in the file

• generates the analysed coloured pixel representation based on the use of the language constructs in the source code file.

• logs the data to an external log file, which is used later in comparison tests.

– The program displays the coloured pixel representation on-screen.

Design– Scanning Algorithm

File Comparison :– This will entail a comparator scanning through

each log file generated for the selected files, creating a resultant text file which will be displayed on-screen with the comparative results.

Open the File

Input a line as a string

Search the string for any relevant structures / variables

If structure or loop construct

Move to end of structure or loop construct

Add the results to a file information array

Log structural information to an external log file

Repeat Until EOF

Close the file

Design The Graphical User Interface (GUI)

– This will be designed to resemble other Win32 applications. It will provide drop-down menu’s and buttons for the user to work with. It will also allow the user to access a Help File. The interface will be intuitive and understandable. The OMT Dynamic Model will be used to ensure good design of the interface.
