# CrystalOS
|
|
|
|
the initial aim of this project was to follow a blog series on how to write an operating system in Rust (see links below)
|
|

|
|
|
|
After reading and implementing the features from the final chapter, (async/await) I could find no further instruction on how to continue
|
|
from that point onwards. The author of the project is working on a third edition but there's no news of when it will be complete.
|
|
|
|
while I'm waiting for the third edition to release, I guess I'm gonna just have to improvise :)
|
|
|
|
- for more details on this project read the wiki ^^^

# Features as of Nov 2023
|
|
|
|
### barebones standard library with the following general features
|
|
- random library for random choice and random integers
|
|
- simple timing library to add delay
|
|
- the delay is not at all accurate as it was hastily put together, this definitely needs to be rewritten
|
|
when i have some more free time XD
|
|
- Stdin and Stdout structs with all the following actions
|
|
- individual keystroke input
|
|
- string input (like a standard terminal)
|
|
- print and println macros for output,
|
|
- same macros are implemented for logging and for serial output (untested using real hardware, does definitely work in QEMU)
|
|
- renderer for sending 'frames' to an 80x25 character ascii display (VGA Mode), these can be arrays of characters, or arrays
|
|
of coloured characters, allowing for more advanced formatting if you need an application to support it.
|
|
- additionally, a trait called element is provided, this will likely be changed significantly in future versions of the OS so the
|
|
details on it's functionality are not important
|
|
- application trait that provides a standardised way for applications to run in the OS.
|
|
|
|
### some basic apps
|
|
- a To-Do list app
|
|
- you can type 'tasks add <task name>' to add a task
|
|
- you can also remove tasks and list them with 'tasks list'
|
|
- snake game
|
|
- pretty obvious what this is but there's also an impossible / chaos mode which adds
|
|
a significant number of AI snakes that aggressively try to pursue the same points of interest
|
|
as the player which can make survival challenging
|
|
(basically a janky snake game crossed with slither.io)
|
|
- conway's game of life
|
|
- just makes some cool patterns, hardcoded starting pattern at the moment but I kinda want to add an editor for it in the future
|
|
- a calculator that uses the same concepts as a compiler / interpreter to evaluate expressions
|
|
- works for arithmetic expressions including powers, also supports functions like ln() and sqrt()
|
|
- adding more functions in the future, recently covered taylor series in A levels so i'm implementing trig functions.
|
|
- it can also graph stuff ig, using "graph" and putting an expression in terms of x with substitute numbers in for x and graph
|
|
y vs x
|
|
|
|
- a shell that can enter apps and run commands like 'echo' and 'clear'
|
|
- well actually just those commands lol. Might try making a shell language or something if i get some spare time over christmas
