How to embed python runtime into my app

[oovm]

I need a custom python runtime without stdlib, I saw an example of this:

https://github.com/RustPython/RustPython/blob/main/examples/hello_embed.rs

but the dependence rustpython_vm seems yanked: https://crates.io/crates/rustpython-vm

How can I do the embed today?

I also don't need freeze-stdlib, can I set it directly to utf-8 here?

RustPython/vm/src/vm/mod.rs

Lines 205 to 215 in 60598b6

	// set up the encodings search function
	self.import("encodings", None, 0).map_err(|import_err| {
	let err = self.new_runtime_error(
	"Could not import encodings. Is your RUSTPYTHONPATH set? If you don't have \
	access to a consistent external environment (e.g. if you're embedding \
	rustpython in another application), try enabling the freeze-stdlib feature"
	.to_owned(),
	);
	err.set_cause(Some(import_err));
	err
	})?;

Try to use latest main branch instead of published version.

Even without stdlib, you have to embed a few python files. Skipping stdlib is possible but builtin-modules are necessary. https://docs.python.org/3/library/sys.html#sys.builtin_module_names

Hello there! Would you mind to help me too?

I created a new Rust binary project with cargo new and copy pasted the hello_embed.rs into the my main.rs file. In the Cargo.toml file I added

# ... Boilerplate cargo.toml stuff and then
[dependencies]
rustpython = {git = "http://github.com/rustpython/rustpython.git", features = ["freeze-stdlib"]}

I believe I'm using the lastest version of this repo, but yet I still get an error where it can't find external crate rustpython_vm. I saw that rustpython_vm is added as a dependency to Rustpython and not a member of the workspace, so because of that I don't know how to separate them.

Is the problem in the way I added rustpython?

Any pointers or help is appreciated! Happy Holidays!

PS: I typed the url from what I remembered but in reality I copy pasted from the GitHub copy button

Just renaming it should do it I believe:

rustpython-vm = {git = "http://github.com/rustpython/rustpython.git", features = ["freeze-stdlib"]}
