pocketpy is a lightweight(~5000 LOC) Python interpreter.
|
|
And this branch is a long-term support version based on `v0.9.3`.
|
|
|
|
It is extremely easy to embed. Including a compiler, optimizer and bytecode virtual machine. All of them are available in a single header file `pocketpy.h`, without external dependencies.
|
|
|
|
Please see https://pocketpy.dev for details or try [Live Demo](https://blueloveth.github.io/pocketpy).

## Getting Started
|
|
|
|
#### C/C++
|
|
|
|
For C/C++ developers, you can download the `pocketpy.h` on our GitHub release page.
|
|
|
|
https://github.com/blueloveTH/pocketpy/releases/latest
|
|
|
|
Check [C-API](https://pocketpy.dev/c-api/vm/) for references. For further customization, you can use [C++ API](https://pocketpy.dev/getting-started/cpp/).
|
|
|
|
```cpp
|
|
#include "pocketpy.h"
|
|
|
|
int main(){
|
|
// Create a virtual machine
|
|
VM* vm = pkpy_new_vm(true);
|
|
|
|
// Hello world!
|
|
pkpy_vm_exec(vm, "print('Hello world!')");
|
|
|
|
// Create a list
|
|
pkpy_vm_exec(vm, "a = [1, 2, 3]");
|
|
|
|
// Eval the sum of the list
|
|
char* result = pkpy_vm_eval(vm, "sum(a)");
|
|
printf("%s", result); // 6
|
|
|
|
// Free the resources
|
|
pkpy_delete(result);
|
|
pkpy_delete(vm);
|
|
return 0;
|
|
}
|
|
```
