Important
Currently supports python-3.11 only.
This package provides a go package named "python" under which most of the PyXYZ functions and macros of the
public C-API of CPython have been exposed. Theoretically, you should be able use https://docs.python.org/3/c-api
and know what to type in your go program.
go >= 1.21python = 3.11.x
brew install python@3.11brew install pkg-config
We will need pkg-config and a working python3.11 environment to build these bindings. Make sure you have Python
libraries and header files installed as well (python3.11-dev on Debian, brew install python@3.11 on macOS, or
python3-devel on Centos for example).
By default pkg-config will look at the python3 library so if you want to choose a specific version just symlink
python-X.Y.pc to python3.pc or use the PKG_CONFIG_PATH environment variable.
go get go.nhat.io/cpy/v3Some functions mix go code and call to Python function. Those functions will return and int and error type. The
int represent the Python result code and the error represent any issue from the Go layer.
Example:
func PyRun_AnyFile(filename string) open filename and then call CPython API function
int PyRun_AnyFile(FILE *fp, const char *filename).
Therefore, its signature is func PyRun_AnyFile(filename string) (int, error), the int represent the error code from
the CPython PyRun_AnyFile function and error will be set if we failed to open filename.
If an error is raise before calling th CPython function int default to -1.
Take a look at some examples and this tutorial blogpost.
We follow the versioning of the CPython API. The version of this package is 3.11.x which means it supports the CPython
API version 3.11. However, the patch version x is used to indicate the version of this package, not the CPython API.
If you see a version 3.11.7, it doesn't mean the module only supports CPython API version 3.11.7, it's just the 7th
time we patch to support the CPython API version 3.11.
Contributions are welcome! See details.
This project is a community maintained successor to DataDog/go-python3, which will get archived in December 2021.
If you use the Go package github.com/DataDog/go-python3 in your code, you can use go.nhat.io/cpy/v3 as a drop-in replacement. We intend to not introduce breaking changes.
This project was inspired by sbinet/go-python (Go bindings for the CPython-2 C-API).
This project was a fork of sublime-security (Go bindings for the CPython-3 C-API) which only supports python 3.10.
