Designing an organized system

[john2496]

Okay, well I started working on my os a few days ago. I've actually been spending most of my time looking stuff up and reading tutorials than actually coding. Now that I've readup on the concepts its time for some actual coding :9.

However the first problem I'm facing is 'how should I structure this thing[codewise]'. I like my source code to be _very_ neat, orderly, and properly layered.

I'm writing up a list of functions I'm going to write and basically how this is going to be implemented. I'm trying to keep seperate parts of the operating system SEPERATE to avoid intermingling code.

Here is what I got so far. I'm asking for suggestions and your ideas on the various libraries that should be written.

   k_move_left
   k_move_right
   k_move_up

perhaps you should seperate the printing and keyboard functions, as you will need a irq etc for keyboard input?

for the user input ... well as long as you are not fetching input from /console (I have four special devices: console1 - console4) via file system, you can as well build in hooks to fetch the characters directly from some kind of input queue (a circular buffer is the best solution for this. Its quick, clean and stable as hell - and easy to implement I use it for many other things too, the circular buffer structure)

Bubach is right btw: keyboard input and 'reading' a character from a device have to be separated strictly. You gonna have troubles if you choose to simplify too much, there's no two ways around that. You *read* from a console and you *write* to a console. Better you provide yourself with those abstractions as soon as possible.

stay safe. I hope everything is clear still. )
