Email address: carlsond@stvincent.edu Parser - An LL(1) Table-Driven Parser--> Download from the Parser Webpage(Posted 01/05/2008, for Windows)This freeware program provides an easy-to-use, table-driven LL(1) parser for educational use. The user supplies the program to be parsed as an input file, as well as files containing tables that specify the grammar rules, the finite state machine used to chop the program up into tokens, etc. The output, if parsing is successful, is an indented form of the parse tree for the given input program. The program can also be used to simply break the program up into a list of tokens, skipping the actual parsing. The .NET framework is needed in order to run this program. QSearch - A Search Engine for Web Pages--> Download(Revised 06/27/2003, for Linux)QSearch 2.1 is a simple search engine for web pages, consisting of a shell script, C++ code for a search program, a small C program, and a couple of html files. It is intended for use on Linux/Unix systems that allow CGI scripts and that have the uncgi program installed. New in version 2.1 is the optional ability to also index files on a Windows server. However, the search engine itself must run in Linux/Unix. The above file is a small gzip-ed tar file. Before using it, verify the md5sum as follows:
md5sum search.tar.gz
The correct md5sum is:
55d02461154122bcaa6761e9f84c328dIf yours matches this, then make a new directory, move search.tar.gz to it, and use the following while in that directory to extract the component files.
gzip -dN search.tar.gz
The last line will extract the files to your current directory.
One of the files is named Readme. Look at it to see if Qsearch is
appropriate for your system and to find the installation instructions.
If you wish to use an older version, follow this link to QSearch 1.7. The correct md5sum for this old version is: b27fd8ef6337ca81c3be61623d7e064a Mic1 - Microprogramming Simulator--> Download(Windows version, last updated 10/29/2001, new example added 03/17/2003)This is a 181 KB WinZip file containing mic1.exe, a microprogramming simulator that runs under Windows. Specifically, it has been tested under Windows 95 and Windows 2000, though it probably runs under most other versions of Windows as well. Included are the mic1.exe simulator, a mic1doc.txt manual, and sample microprograms. The source code is not included. The simulator is useful in teaching computer architecture. The simulated machine is based on the one described in Andrew S. Tannenbaum's popular text STRUCTURED COMPUTER ORGANIZATION, 3rd ed. (Prentice-Hall, 1990). Note that this version of the simulator has several changes and improvements over the DOS version listed below. However, it still simulates the same machine. Mic1 - Microprogramming Simulator--> Download(for DOS)This is a WinZip file containing mic1.exe, a microprogramming simulator that runs under DOS, as well as the C source code, a readme, and sample microprograms. The simulator is useful in teaching computer architecture. This one is public domain software. Parser and Tokenizer--> Download(for DOS)This is a WinZip file containing table-driven parser and tokenizer programs that run under DOS. These are suitable for an introductory course dealing with programming languages, finite state machines, etc. Both the executables and the Turbo Pascal source code are provided. Head Utility--> Download(for DOS)This is a WinZip file containing a DOS imitation of the UNIX head utility. Both the executable and Turbo Pascal source code are provided. deluser - Script to Delete a User in Linux--> DownloadThis is a text file containing a shell script to delete a user's account in Linux. It must be run as root. It will ask whether to save copies of the user's files or not. You may be able to adapt this script to your Linux or other UNIX system. This particular script assumes that shadow passwords are not enabled. ted - A text Editor for Linux--> Download(Revised 01/05/2002)The ted text editor software includes both the executable and C source code for Linux systems. The above file is a gzip-ed tar file. Before using it, verify the md5sum as follows:
md5sum ted.tar.gz
The correct md5sum is:
8004111d63f2c78af07191a95a0063afIf yours matches this, then make a new directory, move ted.tar.gz to it, and use the following while in that directory to extract the component files.
gzip -dN ted.tar.gz
Note that the last line will extract the files to your current directory.
One of the files is a readme file. Begin by looking at it.
ted - A Text Editor for HP-UX--> DownloadThis is an older version of the above ted text editor for HP-UX 10.x systems. The software includes both the executable and C source code for HP-UX systems. The above file is a gzip-ed tar file. Extract the component files using the directions above for the Linux version. tree - Gives Directory Tree in HP-UX--> DownloadThis is a short text file containing C shell scripts for giving a directory tree under HP-UX 10.x. This one is public domain software. Br. David's Home Page
