# ZOS OPERATING SYSTEM
|
||||
|
||||
"I hate computers so much,
|
||||
I wrote an operating system,
|
||||
I still hate computers"
|
||||
|
||||
- Vilyaem
|
||||
|
||||
ZOS (zaws) is a free single-threaded single-user operating system written from scratch
|
||||
in C (ANSI C89), Assembly, and S (its own programming language). ZOS is for the x86-64
|
||||
and *duino architectures. ZOS features a boot loader, kernel, interpreter, shell, text editor,
|
||||
graphics, core utilities, and (optional) filesystem. ZOS' objective is to be an ultrafunctionalist high performant 'suckless'
|
||||
operating system with a heavy focus on simplicity and freedom, ZOS is also designed to be the primary operating
|
||||
system for the quickly approaching collapse of modern secular society.
|
||||
ZOS by default, does not come with a graphical interface, desktop environment, or window manager,
|
||||
it is primarily command line driven. ZOS has no internet/network connectivity, GPU support, segmentation,
|
||||
rings, rootkit, proprietary blobs, WiFi card support, multiple disk support, support for other filesystems (FAT,ext,NTFS...),
|
||||
or USB support, all of these are positives.
|
||||
ZOS only supports its own file system, MiniFS. Operating systems that are most similar, either conceptually
|
||||
or ideologically are 86-DOS (1980), TempleOS (2018), and CollapseOS. ZOS is NOT based off of Unix or DOS.
|
||||
ZOS uses an optional RAM based filesystem, and only very rarily writes to disk, this contributes greatly to the performance
|
||||
of the system, as a hard disk is the slowest form of memory to access and alter, also some systems, especially embedded
|
||||
devices, do not have harddisks.
|
||||
|
||||
ZOS can easily be compiled and emulated on POSIX, DOS, and Windows machines
|
||||
so that users may develop or learn the operating system.
|
||||
|
||||
---
|
||||
|
||||
I, Vilyaem, have created ZOS over the course of a couple weeks.
|
||||
I wanted a system that could be for once considered both 'lightweight' and effective.
|
||||
The system with its clear and sober mission absolutely clobbers
|
||||
horrid disasters such as gnooh/Linux and Windows, software should be designed
|
||||
absolutely perfectly and last for eternity, akin to the Roman Empire,
|
||||
or the word of God. This is not even the goal of most software production,
|
||||
so its not a mystery why modern computing is an unending disaster.

## CONTRIBUTION, WORKFLOW, SOURCE GUIDE
|
||||
|
||||
There is no 'c*de of c*nduct'.
|
||||
The issue/bug tracker is in the 'bug' file. Keeps this project independent from online issue tracking hosts.
|
||||
|
||||
Filemap:
|
||||
.
|
||||
├── README.md -- this file
|
||||
├── bug -- bugs & issues go here
|
||||
├── c.sh -- compiling script
|
||||
├── main.c -- the entire source code
|
||||
└── zos -- emulator executable
|
||||
|
||||
1 directory, 5 files
|
||||
|
||||
run ``./c.sh`` to compile the simulator.
|
||||
run ``./c.sh X86`` to compile a bootable x86-64 image.
|
||||
run ``./c.sh DUINO`` to compile for arduino.
|
||||
|
||||
Importance scale in issue tracking
|
||||
1 - last concern
|
||||
2 - important
|
||||
3 - right now!
|
||||
|
||||
## STATUS
|
||||
|
||||
ZOS is under heavy construction, at this point it is a proof of concept.

1 3 Not done Fix loops in S? S seems to have some loop bugs, investigate this further, I think the state-machine-like\nway of handling loops is interesting.
|
||||
2 3 Not done Finish core, finish emulator. \nFinish the emulated operating system.\n\nS - 8/10\nVedlin - 9/10\nKernel/libc - 1/10\nGraphics 0/10\n\nFor now we dont need to implement IO to disk, everything is temporal.
|
||||
0 3 Done! Make vedlin use filesystem functions Vedlin is reimplementing functionality that should really be handled by the filesystem?
|
||||
5 3 Done! Prompts are broken? \nWhen working on the Vedlin editor I notice that it will ask for a line number\non some operations, but will not ask the user for a string, this could be associated with the\nCIA and MIT bugs.\n\nSOLVED: scanf and fgets just mess each other up
|
||||
4 3 Done! bugs caused by CIA and MIT For the past day and a half I have been scratching my head on a segmentation fault\nsupposedly caused by a call to strcpy, sounds like a trivial problem, but it turns\nout that is not the case, I thought it was related to scoping, it was not that either,\nwhen I switched compilers to TCC, tcc does not like having variable declarations in\nswitch cases, so after fixing them the program works just fine, on gcc it\nalways crashes. 'cproc' with its QBE backend never finishes compiling, qbe just\nperpetually hogs 100% CPU in the background. Must a combination of weird bugs that\nnestle in perfectly with minute compiler bugs. \n\nsolution: write your own compiler and assembler and or abstract stuff that could be\ntripping up\n\nGCC sucks\nGDB sucks\nTCC sucks\nQBE sucks\nLinux sucks\n\nSOLVED: This seems to have fixed it self, bad libc usage???
|
||||
10 1 Not done Implement graphics into S \nUse SDL2 for emulator, VGA for x86, and some standard text buffer for arduino.\nThis requires implementation of built-in function calling. The Operating System,\nif it uses color, will at most be 640x480 16 color.\n\nFunctions required\n\n\n::GR_INIT -- intialize graphics\n::GR_CLR -- Clear the screen\n::GR_SETCOL -- Set color to stackptr-1(1-16)\n::GR_PLOT -- Plot pixel, stackptr-2(x) stackptr-1(y)\n::GR_SPR -- Draw a sprite in RLE 16 color, all sprites are square resolution, stackptr-1 is res, the rest is data\nuntil you hit -1
|
||||
11 3 Not done Add string pushing. \nAdd the ability to push an ASCII string onto the stack.\n\nLike this\n\n."Hello World"
|
||||
9 3 Done! Vedlin and VedlinWriteFile bugs \nThe first byte of 'vedfilename' is somehow becoming a newline?\nIs this a libc issue?\n\nThe first byte of 'strbuf' is becoming null, I dont think I am \ncomposing a string array into a single stringe seperated by newlines \ncorrectly.\n\nVedlin Load File also seems broken.\n\nIf these bugs are fixed then ZOS can be considered finished as a proof of concept.\n\nSOLVED:\n\nThis involved a big rewrite, also just removing some bad code.
