Update !

Got the argument parsing work



I planned command input like this : when you input a command, you can specify two kinds of parameters, classic and special. A special parameter is the minus character - followed by one letter, and a classic parameter is at least one letter, A to Z, or one number, 0 to 9. Special parameters will be copied to another memory area than classic parameters so they'll be easier to handle by user programs.

As I said sonner, each and every command will be a program stored in the filesystem (currently working on it) and which will be ran with the given arguments, if any. So, the OS itself will be a tiny command-line which can run programs, a filesystem, and many, many functions for the programmers to use in their programs.

The main interest of this OS is that I try to make it use as little RAM as possible, so there will be a great free space for user programs. Also, I try to provide as many routines as possible to make user programs as small as possible, allowing for even more features in each.

[hs]The downloadable F-Zero demo ? I never found this one anywhere, are you able to send it to me please ?[/hs]

Anyway, jacobly will your emulator able to run custom OSes ?

Update !

After long hours of work, I've finally got backspace erasing working !



You can't imagine how frustrating it was for me

I use IY register to pass buffers to functions. And with this system of flags you can't define your own - prefixed arguments. For example, that would fit if there was a fixed number of allowed - prefixed options.

aeTIos : maybe I'll never do that

Xeda112358 : that's what CLS is doing o_O and for the '?' thing, I planned something for arguments when the functions will be programs, so you'll can do command -h.

Hey guys !

A few days ago I started working on cmdOS, a command line-based 3rd-party OS. I only do that as a training to improve my ASM skills, so I don't plan any future for it. But hey, who knows ?

I started with SirCmpwn's OS starter kit, which provides LCD and flash set up, RAM unlocking and memory mapping. I also used KnightOS's fontmap and putSpriteOR routine with the agreement of SirCmpwn, but I wrote myself everything else (that means, the text routine, the interpreter, and other functions that you don't see in the screenie below).

So, for now the OS boots on a command-line, which fully supports functions with no arguments so if you can think of one, please tell me.

Here are the functions already available :

• SHUTDOWN : guess its use
• CLS : clear the command-line
• PING : prints "Pong !"
• VERSION : prints cmdOS's version

Of course, screenie :



Also, I don't show it in the screenie because I thought of it just after uploading the image, but the text wraps when you reach the bottom and the right edge of the screen :)

Oh no I meant above the broken road, sorry x)

And yeah, I'll try it right now
