Class bradel.wordchanger.WordChanger 

java.lang.Object
   |
   +----bradel.wordchanger.WordChanger
public class WordChanger
extends Object
WordChanger reads in a set of java files and changes all of the method and variable names so as to make the files hard to read once they are compiled. This will not work with escape sequences, so A will not be translated to an 'a'. Values that will be replaced are all of the form: [a-zA-Z][0-9a-zA-z_]* so the Java behaviour of using dollar signs and whatever else is not considered. String constants will be ignored. Comments will be ignored. This program does not examine the java program structure to identify keywords which should not be changed. Words that are not to be changed are either java keywords or are specified in a set of files. Creation date: (30/12/2001 1:34:00 PM)

Author:
: Borys Bradel Copyright (c) 2001 Borys Bradel All rights reserved Command prompt: If no parameters, reads WordChanger.cfg as the default configuration file. Otherwise the first parameter has to be the name of the configuration file. Configuration file format: Each line has to be a tag word followed by one or more tokens (as specified by StringTokenizer. If a tag is omitted then what is in square brackets is assumed. The lines are as follows: {base_directory some_directory [default=""]} {package_directory some_directory [default=""]} {changed_file_directory some_directory [default="changed"]} {prefix some_prefix [default="bb"]} {exclude_from file1 file2 ... [default: none]} {not_scanned file1 file2 ... [default: none]} {debug boolean_value [default: false]} {conversion_data_file file_name [default=null]} {reverse_from file_name [default=null]} The directories are combined as follows to look for java source code files: base_directory + package_directory for input files and base_directory + changed_file_directory + package_directory for output files. The java file names are just concatenated with these directory names, so they must have a / at the end (also, whether to use a / or a \ may be system specific).
