classfind.jar - the .jar file to use

classfind.tar.gz - the source code and scripts

Usage

classfind is designed to be invoked from editors, shell completions etc. Consequently you'll want to wrap it in a script, such as:

#!/bin/sh
java com.oopsconsultancy.classfind.Main $*

classfind operates by analysing the environment's CLASSPATH, and building a mapping of classes vs. their packages and their location in the CLASSPATH. This mapping is stored in a file called .classfind, located (unless specified otherwise) in your home directory.

classfind options:

-h : displays help
-r : rebuilds the cache
-d : disables duplicate package display
-c [class] : finds the given class
-v [class] : generates the complete package name for the given class
-f [file] : the classfind cache file to use
-p [pkg] : the package to expand from

eg.

example% classfind -c Document
/usr/java/j2sdk1.4.0/jre/lib/rt.jar -> org.w3c.dom.Document
/usr/java/j2sdk1.4.0/jre/lib/rt.jar -> javax.swing.text.Document

highlights that you can access a Java Document object from two packages, both from within the same .jar file.

Other uses for classfind

Generating import statements and generating Javadoc help urls from within editors. vim configurations available on request.

Zsh command line completion. Works in a similar way to filename completion. Insert the following in your .zshrc

function classpaths { 
	reply=(`classfind -p $1 $2 2>/dev/null`)
}
compctl -S "" -X "Completing with %n Java class(es)" -K classpaths java jdb ddd sco jquiz
