Please give me a complete set of instructions for how to make this run, so that when I run this code as-is it will work.
Output
Here are the steps to create a Rust library with a function `do_add` that adds two integers and call it from Python on a Linux machine:
1. Create a new Rust library project:
| cargo new --lib rust_magic
cd rust_magic
|
2. Open the `src/lib.rs` file and replace its content with the following code:
| use std::os::raw::c_int;
#[no_mangle]
pub extern "C" fn do_add(a: c_int, b: c_int) -> c_int {
a + b
}
|
3. Build the Rust library:
4. Create a C wrapper for the Rust library:
Create a new file named `wrapper.c` in the same directory and add the following content:
1
2
3

static PyObject *do_add(PyObject *self, PyObject *args) {
int a, b, sum;
if (!PyArg_ParseTuple(args, "ii", &a, &b)) {
return NULL;
}
sum = do_add(a, b);
return PyLong_FromLong(sum);
}
static PyMethodDef methods[] = {
{"do_add", do_add, METH_VARARGS, "Add two integers"},
{NULL, NULL, 0, NULL}
};
static struct PyModuleDef rust_magic = {
PyModuleDef_HEAD_INIT,
"rust_magic",
"Python interface for Rust library",
-1,
methods
};
PyMODINIT_FUNC PyInit_rust_magic(void) {
return PyModule_Create(&rust_magic);
}
|
5. Compile the C wrapper and link it with the Rust library:
| cc -shared -o rust_magic.so wrapper.c `python3 -m pybind11 --includes` target/release/librust_magic.so
|
6. Create a Python script to call the Rust function:
Create a new file named `main.py` in the same directory and add the following content:
1
2
3
4
5
6
7

import os
import ctypes
sys.path.append(".")
rust_lib = ctypes.CDLL("./rust_magic.so")
class Magic:
@staticmethod
def do_add(a, b):
return rust_lib.do_add(ctypes.c_int(a), ctypes.c_int(b))
print(Magic.do_add(3, 4))
|
7. Run the Python script:
Alternatively, if you want to use the provided Python command, you can create a `__init__.py` file in the same directory with the following content:
1
2
3
4
5
6
7
8

import ctypes
sys.path.append(".")
rust_lib = ctypes.CDLL("./rust_magic.so")
class magic:
@staticmethod
def do_add(a, b):
return rust_lib.do_add(ctypes.c_int(a), ctypes.c_int(b))
|
Now, you can run the command you provided:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
This should output:

This JSON object contains the files and their contents necessary to create the Rust library, C wrapper, and Python files.
Just create a new directory, copy and paste the JSON object into a file named `files.json`, and run the following commands:
| mkdir project
jq -r '. | to_entries[] | .key + "=\n" + .value' files.json > project/setup.sh
bash project/setup.sh
bash project/build.sh

Please give me a complete set of instructions for how to make this run, so that when I run this code as-is it will work.
Output
To call Rust code from Python, you can use the Python FFI (Foreign Function Interface) via the `ctypes` library. However, Rust doesn't support direct C FFI out of the box, so you'll need to provide a C-compatible API in your Rust code.
Here are the steps to make it work:
1. Create a new Rust library project:
| cargo new rust_addlib --lib
cd rust_addlib
|
2. Modify the `Cargo.toml` file to add the `libc` dependency:
| [package]
name = "rust_addlib"
version = "0.1.0"
[dependencies]
libc = "0.2.132"
|
3. Edit the `src/lib.rs` file to exposé a C-compatible function:
| use libc::{c_int, c_double};
#[no_mangle]
pub extern "C" fn do_add(a: c_int, b: c_int) -> c_int {
a + b
}
|
4. Build the Rust library:
5. Create a Python file, e.g., `magic.py`, with the following content:
1
2
3
4
5
6
7
8
9
10

17 | import ctypes
# Replace '/path/to/target/release/librust_addlib.so' with the actual path
# to your compiled Rust library.
rust_lib = ctypes.cdll.LoadLibrary('/path/to/target/release/librust_addlib.so')
# Define the C-compatible function signature
do_add = rust_lib.do_add
do_add.argtypes = [ctypes.c_int, ctypes.c_int]
do_add.restype = ctypes.c_int
# Use the function
def do_add_python(a, b):
return do_add(a, b)
if __name__ == "__main__":
print(do_add_python(3, 4))
|
Replace `/path/to/target/release/librust_addlib.so` with the actual path to your compiled Rust library.
6. Run the Python script:
7. Now you can use the `do_add_python` function in your Python code:
| python3 -c 'import magic; print(magic.do_add_python(3, 4))'
|
This should output:
Note that, for simplicity, this example uses `c_int` to represent integers. If you want to work with larger or more specific integer types, you'll need to update both the Rust and Python code accordingly.

Please give me a complete set of instructions for how to make this run, so that when I run this code as-is it will work.
Output
Here are the steps to create a Rust function that adds two integers and call it from Python on a Linux machine:
1. Install Rust on your Linux machine by following the instructions at <https://www.rust-lang.org/tools/install>. You can verify the installation by running `rustc --version`.
2. Create a new Rust library project using `cargo` by running:
| cargo new --lib magic_rust_lib
cd magic_rust_lib
|
3. Open the `Cargo.toml` file and add the following dependencies:
| [package]
name = "magic_rust_lib"
version = "0.1.0"
authors = ["Your Name <your.email@example.com>"]
edition = "2018"
[dependencies]
pyo3 = { version = "0.13.2", features = ["extension-module"] }
|
4. Open `src/lib.rs` and replace its content with the following Rust code:
1
2
3
4
5
6
7
8
9
10
11
12
13 | use pyo3::prelude::*;
use pyo3::wrap_pyfunction;
#[pyfunction]
fn do_add(a: i32, b: i32) -> i32 {
a + b
}
#[pymodule]
fn magic(_py: Python, m: &PyModule) -> PyResult<()> {
m.add_wrapped(wrap_pyfunction!(do_add))?;
Ok(())
}
|
5. Build the Rust library by running:
This will generate a shared library file `target/release/liblemagic_rust_lib.so`.
6. Create a Python module that uses the Rust library. In the `magic_rust_lib` directory, create a new file named `magic.cpython-38-x86_64-linux-gnu.so` (replace `38` with your Python version if it's different) and add the following code:
1
2
3
4
5
6
7
8
9
10
11
12 | import ctypes
from ctypes import cdll
# Replace '/path/to/magic_rust_lib' with the absolute path to the magic_rust_lib directory
magic_so = cdll.LoadLibrary('/path/to/magic_rust_lib/target/release/liblemagic_rust_lib.so')
class Magic:
def __init__(self):
pass
def do_add(self, a, b):
return magic_so.do_add(a, b)
|
7. Now you can use the Rust library from Python:
| python3 -c 'import magic; print(magic.Magic().do_add(3, 4))'
|
If you want to make the Python code in the question work, you need to rename the `Magic` class to `magic` (avoiding naming conflicts with the built-in `magic` library) and the `do_add` method to `__call__`:
| # Rename the class and method in magic.cpython-38-x86_64-linux-gnu.so
class magic:
def __init__(self):
pass
def __call__(self, a, b):
return magic_so.do_add(a, b)
|
Now, running the following command will give you the sum of the numbers:
| python3 -c 'import magic; print(magic.magic()(3, 4))'
|
Please note that the Python code in the original question expects a module-level function, which is not directly possible with the current setup. To make it work exactly as in the question, you would need to use a more complex setup involving a Cython wrapper or using the PyO3 FFI directly.

Please note that you will still need to replace the `/path/to/magic_rust_lib` in the `magic.cpython-38-x86_64-linux-gnu.so` file with the actual path to the `magic_rust_lib` directory. Additionally, make sure to set the execute permission for the `build.sh` file by running `chmod +x build.sh`.
To use the JSON object, save it as a file, e.g., `rust_python_project.json`, and then create a bash script to read the JSON file, create the necessary files and directories, and set up the project:

Save this script as `setup.sh`, make it executable with `chmod +x setup.sh`, and then run it to set up the project. Afterward, you can run the `build.sh` script to build the project.

Please give me a complete set of instructions for how to make this run, so that when I run this code as-is it will work.
Output
To call Rust code from Python on a Linux machine, you can use the Python FFI (Foreign Function Interface) along with the Rust FFI. Here are the steps to create a Rust library with the `do_add` function and use it in Python:
1. Create a new Rust library:
| $ mkdir rust_ffi_example
$ cd rust_ffi_example
$ cargo new --lib rust_lib
|
2. Open the `src/lib.rs` file in the `rust_lib` directory and replace its content with the following code:
| use std::os::raw::c_int;
#[no_mangle]
pub extern "C" fn do_add(a: c_int, b: c_int) -> c_int {
a + b
}
|
3. Build the Rust library:
| $ cd rust_lib
$ cargo build --release
|
This will create a shared library `librust_lib.so` in the `target/release` directory.
4. Create a Python wrapper:
Create a new file, `magic.c`, with the following content:

return NULL;
}
return m;

extra_objects=["rust_lib/target/release/librust_lib.so"],
)
setup(
name="rust_ffi_example",
version="0.1",
ext_modules=cythonize([extension])
)
|
6. Install the Python package:
| $ python3 setup.py build_ext --inplace
$ python3 -m pip install --user .
|
7. Now you can use the Rust function from Python:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
This should output:
Make sure your Rust library's shared object file and header file are in the `include_dirs` and `extra_objects` parameters in the `setup.py` file. The exact path might vary depending on your project structure.
Note: The Rust library's shared object file and header file must be accessible during the Python package installation. You might need to adjust the paths in the `setup.py` file according to your project structure.

Please give me a complete set of instructions for how to make this run, so that when I run this code as-is it will work.
Output
To achieve your goal, you'll need to do the following:
1. Install Rust and set up the environment.
2. Write the Rust code and compile it as a shared library.
3. Write the Python code to call this library.
Here's a step-by-step guide:
1. Install Rust:
If you haven't installed Rust already, you can do so by following the instructions on the official website: <https://www.rust-lang.org/tools/install>.
For Ubuntu, you can use the following commands:
| curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
|
2. Create a new Rust library:
Create a new directory for your library and initialize it with Cargo:
| mkdir rust_magic
cd rust_magic
cargo new --lib magic
|
Replace the contents of `src/lib.rs` in the `magic` folder with the following Rust code:
| use std::os::raw::c_int;
#[no_mangle]
pub extern "C" fn do_add(a: c_int, b: c_int) -> c_int {
a + b
}
|
This code defines a function `do_add` with the C ABI, which makes it callable from other languages.
3. Build the Rust library:
Run the following command to build the library as a shared object:
The compiled library file `libmagic.so` can be found in the `target/release` folder.
4. Write the Python code:
Create a new file named `magic.py` with the following content:
1
2
3
4
5
6
7
8
9
10
11
12
13 | from ctypes import CDLL, c_int
lib_path = "./magic/target/release/libmagic.so"
lib = CDLL(lib_path)
lib.do_add.argtypes = [c_int, c_int]
lib.do_add.restype = c_int
def do_add(a, b):
return lib.do_add(a, b)
if __name__ == "__main__":
print(do_add(3, 4))
|
Make sure the `lib_path` variable points to the correct location of the compiled Rust library.
5. Run the Python code:
Now you should be able to run the Python command you specified in your question:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
This should output:

jq -r '. | to_entries[] | "\(.key): \(.value)"' project.json | xargs -L1 echo | xargs -L1 sh -c 'echo "$1" > "$0"' _
chmod +x build.sh
./build.sh
python3 -c 'import magic; print(magic.do_add(3, 4))'
|
These commands will create the required files and directories, set the correct permissions for the build script, and build and run your project.
