Sample Code from Course Directories

Topics:

I've written all the code provided here, except where explicitly attributed to another author. Most of the code was written to:

• Illustrate design ideas for my classes
• Implement a few of the harder projects to show ways that can be done
• Make tools for managing my own code
• Demonstrate language features and quirks

Of course, the flow of ideas is two-way. I also adopt good ideas and techniques used by my TAs and students. Since I write a lot of code, as well as teach large classes, and advise research projects, I cannot always test my code as thoroughly as I would like. For that reason, I cannot warrant this code for any specific use. You are free to use my code in any way you think fit, but the responsibility for its correct operation in your programs and environment is yours. Feel free to offer constructive criticism of any of the code you find here.

Tools Folder
Code Analyzer written in C++  More
Comes with a simple WPF app that selects paths and supplies command line arguments. Output is a list of functions and methods, by package, with function size and complexity metrics. TAs and I use this tool to analyzer your project code, so you may wish to use it, yourself, before submitting projects. Code Webifier  More
Tool to convert source code for webpage presentation, by embedding code in <pre>...</pre> blocks, with markup character escaping and suitable styling. The tool writes its output to a console, so the block can be cut and pasted directly into web pages. Code Differences using WPF GUI  More
This tool uses Windows FC - file compare - tool via a WPF interface that supports browsing for files and displaying differences in a text block. Duplicate Files  More
Console application that finds all the paths to each file, e.g., multiple files with the same name in different locations. File Dates  More
Lists files matching one or more patterns, ordered by their last modfication time-date stamps. File Sizes  More
Lists files matching one or more patterns, ordered by their file sizes. Regular Expressions Helper  More
Lists file lines and/or matches resulting from searching each line of a file for regex match. Pretty Print  More
Uses a GUI to select files, then sends nicely formatted representations to a selected printer. Text Finder  More
Displays a list of fully qualified file names from a selected directory tree that all contain a specified text fragment.

Include Headers, Libraries, Using Libraries in Builds
These will eventually contain header files and libraries for each of the packages in the Repository. Graph<V,E> - C++ Directed Graph library

Provides capabilities to extract information from the linux file system, e.g., directories, files, and paths. MTree
Implements an M-ary Tree data structure, e.g., unbalanced tree where any vertex may have an arbitrary finite number of children. C++ code Tokenizer  More  More
Tokenizers extract words, called Tokens, from a stream, e.g., file or stringstream. Lexical scanners form token collections using Tokenizers, to begin the process of code analysis. C++ Lexical Scanner  More
This Lexical Scanner collects tokens from the Tokenizer, above, and uses tokens "{", "}", ";", and "\n" for lines beginning with "#" to terminate a token collection, called a semi-expression. Semi-expressions are the basis for code analysis, as used in the Parser, below. C++ code parser  More
This Parser is a core part of several of the projects listed on this page, include the CodeAnalyzer. Parser is a container for Rules and Rules are containers for actions. Each rule is a detector of some grammatical construct. When a rule matches a token sequence (called a semi-expression) it invokes its actions. C# code Tokenizer  More
Functionality similar to the C++ tokenizer, but written in C#. C# Lexical Scanner  More
Functionality similar to the C++ Lexical Scanner, but written in C#. C# code parser  More
Functionality similar to the C++ code parser, but written in C#. Sockets - Windows

Same as above, but ported to Linux. C++ Comm with File Transfer  More
Implements asynchronous message-passing communication channel, using Sockets, passing HTTP style messages. Files are chunked by a Sender and sent in message bodies. Chunks are reassembled into a file at the Receiver. C# Comm with File Transfer  More
Implements asynchronous message-passing communication channel, Windows Communication Foundation (WCF), passing HTTP style messages. Files are chunked by a Sender and sent in message bodies. Chunks are reassembled into a file at the Receiver. Process
Provides a C++ class wrapper for the Win32 process creation API. Utilities
Provides a miscellaneous collection of low-level utilities for C++ string handling and display, type conversions, and testing.

• DemInher - illustrates syntax and issues with inheritance
• several other small, not as important, low-level demos

Look at DemComp and DemInher carefully. They demonstrate how constructors and destructors are called, some circumstances when temporaries are created, and most importantly why you must use initialization sequences for all the constructors you write (with the exception of default constructors).

I haven't taught CSE686 - Internet Programming for several years, so most of these examples are out-of-date.
