DISCLAIMER: These notes are from the defunct k8 project which precedes SquirrelJME. The notes for SquirrelJME start on 2016/02/26! The k8 project was effectively a Java SE 8 operating system and as such all of the notes are in the context of that scope. That project is no longer my goal as SquirrelJME is the spiritual successor to it.
Yes, this new way of doing things should cause less craming in the way code is to be done.
What I can do to simplify hairball is I can move more bits into Java then I can easily solve building and running hairball on Windows and other systems as I can leverage Java instead of putting lots of work into shell scripts and porting them to other systems. Could also solve the difference of the command intrepreter being different on ReactOS compared to WINE. Then if there is another type of shell system that Java runs on, that can be abstracted also.
Using this launcher script, I can now have actual compilation in Windows since Java will handle the bulk of building and such. I currently have it tested in WINE and it works there.
