Create a Processing library

Compile a Processing sketch into a library that can be used with an import. This is helpful to reduce the amount of Processing tabs in a project, specially for that bunch of classes that won't be changed and belong to a same conceptual group.

Translate Processing's .pde files to .java files, getting rid of all the Processing core functions by java equivalents (ex. sin() to Math.sin()) and/or import Processing classes (ex. PVector). Add package name at the beginning of every java class file.

Open Terminal and go to sketch's directory. Type the following command

javac -cp [processing_path]:[extra_libraries] -source 1.6 -target 1.6 -d . *.java

Processing core path should be something similar to /Applications/Processing.app/Contents/Java/core/library/core.jar in macOS. Add extra library paths (if any) after Processing's core, separated with :. Be aware to fix all compilation errors that may appear.

Create .jar file running

jar cvf [library_name].jar [input_directory]

Move the jar file inside a library directory in the Processing's libraries directory.

Import the brand new library to your sketch 🎉
