It's Friday, it's nearly my Birthday, it's time to address some long running iterative projects (projects I never finish) LRIP for short 🪦.
I have a bunch of these projects which I may one day finish.
One in particular which I really wanted to make possible but have been less experienced in previous iterations, a virtual file system.
The kernel 🐣🍗 is the entry point of an application (aka your computer) which a Filesystem sits on top of, the kernel provides syscalls to do things like change directories, write files and so on, these syscalls are usually C functions (that's it, no magic, although FYI Rust 🦀 is entering the chat).
Okay so we got functions, an application and how do we use this application?
How do you use your computer without a GUI? That's a trick, don't answer that because terminal is graphical, kind of... But yes a terminal, but the shell, that's what we are talking about.
Think of the most basic shell... Shell not Bash, just Shell, it's just a parser really, type 'cd' and the shell parses your input,
cd is not in your bin it's a syscall
chdir(), cool right? 😴, Wake up ☺️
- A web server / application with a limited and synced to phisical disk
- Some sort of mock FS testing
- Deploy a yeoman style template in node.js
- Build an OS real or otherwise
- Build the next docker 😅
- Browser mock FS
- Wasm FS thing
- hybrid synchronized FS
- some new build system concept
- Port it to Rust
- Make it work on a real disk (it's possible with Fuse)
So I'm on my phone, I can't go explaining the code because it's not done yet, BUT it's intuitive I feel, also it's locked down as much as possible so that only a
new Shell() can actually interact with the FS just like the real thing.
Such a fun toy, want to help me, get in touch we can FOSS it 🦄
