## Demo
|
|
|
|
The `_demo` directory contains our demos (it start with `_` to prevent the `go` command from compiling it):
|
|
|
|
* [hellopy](_demo/hellopy/hello.go): link Python to Go and say `Hello world`
|
|
* [clpy](_demo/clpy/cleval.go): compile Python code and eval.
|
|
* [callpy](_demo/callpy/call.go): call Python standard library function `math.sqrt`.
|
|
|
|
### How to run demos
|
|
|
|
To run the demos in directory `_demo`, you need to set the `LLGO_LIB_PYTHON` environment variable first. Assuming you use Python 3.12, and the `libpython3.12.so` (or `libpython3.12.dylib` or `python3.12.lib`) file is in the /foo/bar directory, then you need to set `LLGO_LIB_PYTHON` to:
|
|
|
|
```sh
|
|
export LLGO_LIB_PYTHON=/foo/bar/python3.12
|
|
```
|
|
|
|
For example, `/opt/homebrew/Frameworks/Python.framework/Versions/3.12/lib/libpython3.12.dylib` is a typical python lib location under macOS. So we should set it like this:
|
|
|
|
```sh
|
|
export LLGO_LIB_PYTHON=/opt/homebrew/Frameworks/Python.framework/Versions/3.12/lib/python3.12
|
|
```
|
|
|
|
Then you can run the demos in directory `_demo`:
|
|
|
|
```sh
|
|
cd <demo-directory> # eg. cd _demo/hellopy
|
|
llgo run .
|
|
```
