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.
Now that the main code has been commonized, things look much simpler and nicer now.
A variadic list of localized strings would be interesting for specific cases such as help usage.
For parsing the project file JSON, I will be using it much so I should have a standard class in the API package for handling project packages and whatnot, then I can also use that for the currently installed database of packages and such. Another advantage of JAR files (despite the slight compression speed loss) is that they do not require unpacking and are easier to manage compared to traditional setups where everything must be extracted before it is used.
Despite ServiceLoader not being part of Java 5, it appears GNU Classpath may include it. It may just be partial Java 6 class support. The main thing I need to implement now is the JSON code and directory sweeping code for building source package databases for the specified root tree so that host packages may be built.
I bought a replacement laptop keyboard.
In my common API I will need package information and directory information to exist there so that functionality is not duplicated all over the place.
Time to do some math, there are 4,240 classes in the main library. One class per day would take almost 12 years to implement. To implement the entire library in a single year, I would have to implement 11 classes per day. To implement the entire library in 3 months, I would have to implement at a rate of 50 classes per day. Quite a long run. I obviously would have to streamline things to make implementing things faster. You may be thinking about interfaces being just rather bland, however they still need to be documented and Java 8 does add concrete methods in interfaces. I will have to figure that all out when I get to that point. The first goal should obviously implement compact1 first then once that is complete, move to compact2, then to compact3, then finally all the UI stuff.
Results of class analyzing: compact1 has 1,247 classes; compact2 has 319 classes; compact3 has 541 classes; the rest has 2,134 classes.

This assumes no distraction and just implementing everything in the standard library. So statistically, this will take quite some time to implement so I will need to write some sort of IDE later for development to speed up development time since I currently use just a standard text editor. That way I can have auto formatting, auto documenting, referencing and such, to simplify all of the work I need to do. Perhaps documentation stealing could be done in that when I extend off a base class I can "see" the super class stuff and cherry pick things.
I will need to develop a very efficient IDE designed to save me time implementing things, tab completion for example would save me many key strokes, an internal debugger would quickly find errors and such. The IDE's code itself would have to be sufficient also. Possibly when GUI time comes, I can have a RAD design tool for graphical interfaces, that would be neat. Maybe some advanced features like multiple insertion points would be handy, automatic insertion, adaptive coding, and more. Would need context sensitive based on what is being typed, so say if the return type was String it can suggest any method that returns a String. IntelliJ IDEA looks like a nice IDE, however it costs and it does not support fossil at all and is quite a hefty price, I can buy a new laptop with the cost of a license, at least the commercial version. With the cost of the individual version I could buy a new PowerBook G4 used.
Writing an IDE would be much work, however it would improve efficiency greatly which would negate the undesirable loss of time at this current state. However, since it would be in Swing I would not be able to use it on my own operating system until I implemented GUI support.
However, I could always add a minimal set of classes just to get the IDE working on my own OS however. I should work on the IDE after I write my initial package manager so that way I do not have to use hacky shell scripts to build the IDE itself. Then I can add support for the package manager in the actual IDE to manage every single project rather than randomly jumbling around project files. Then I can use the IDE to develop the compiler so that language based feature stuff could be used, such as error checking. So writing an IDE would be quite helpful. Then later on of course when I get to an actual run- time running on real hardware I can have a debugger integrated into it to simplify those operations, provided the system being debugged does not go berserk.
At least now everything will be using JSON stuff to store data so I do not have to worry about my JSON implementation going rarely used.
The problem with JsonObject and JsonArray are that they are immutable which mean I cannot fully mess around with the objects without recreating everything, so the best choice will be to keep it as a builder sort of. Or I can just have a top level builder. What I really need is an Immutable JSON representation.
Perhaps I can just use a translation layer from an immutable object to a map that I could freely modify for my own needs. JsonObject is a Map and there are map copying things.
