Although Jalopy ships with sensible default settings (mimicking the Sun Java coding convention), you most likely want to configure the formatter to match your needs (adding copyright headers, tune Javadoc handling and the like). For such, Jalopy comes with a graphical configuration tool that lets you interactively customize the settings. See Chapter 2, Configuration for an in-depth discussion of the available options.

To display the settings dialog you should use the provided wrapper script for your platform, called jalopy.xxx (available in the /bin folder of the distribution).

% jalopy --configure

Jalopy comes as an executable JAR file, you therefore can make use of the -jar option of the Java launcher:

% java -jar jalopy-1.9.3.jar --configure

Or you give the class path directly to the launcher

% java -cp jalopy-1.9.3.jar Jalopy --configure

Of course, you can externally configure the class path yourself by adding all .jar files as usual and then type

% java Jalopy --configure

on the console.
