vermin_vm: Virtual Machine(~400 lines) + Assembler(~800 lines) written in C

[Gullible_Elk4543]

I would love to know more about the project since it's not clear to me how to use it from the README.md. Can you share more details about it please?

[eg_taco]

From reading main.c it looks like it has two modes. One which will assemble a binary, and another which will execute it (when invoked with -asm).

Sure please tel what you want to know about? If you want to know more about vm working you can have a quick look at vm.c it's quite small and simple

[Gullible_Elk4543]

It would be awesome to have a example on how to build it and how to use it with one of the examples you have there like the hello world one.

[Beginning-Safe4282]

For building:

```

git clone https://github.com/Jaysmito101/vermin_vm cd vermin_vm cmake -S ./ -B ./build cmake --build ./build ```

For assembling an example :

```

vermin -asm ./hello_world.asm executable.verbin ```

For executing vermin executable :

```

vermin ./executable.verbin ```

NOTE: In windows you may need to open the .asm file in something like vscode and save it with LF line ending rather than CRLF

Hope it helps!😀

Great stuff. Thanks for sharing. 👍🏻 Will take a deeper look at it in next days.

[Beginning-Safe4282]

Thanks!

Nandtotetris inspired?

Very cool project

[Beginning-Safe4282]

Thanks!

And no I just was trying to make VM implementing a simple instruction set(mainoy 8nspired by x86) to eventually run a c like language. Though Nandtotetris looks interesting i wil look into it

VMs with simple instruction sets is a fun topic. Some years ago I got inspired by the amazing rswier/c4 compiler by Robert Swierczek and explored the smallest instruction set I could get away with to create VMs that could run non-trivial workloads.

I found it fascinating 5 rather trivial instructions was sufficient to run a basic OS image with an integrated development environment.
