A Golang runtime Python plugin library

Introduction

This library is a Golang plugin library that allows executing Python code within a Golang runtime. It is based on the execjs library, which provides a way to execute JavaScript code within a Golang runtime.

中文

Requirement

The environment variable PATH must contain the path to the Python executable.

Install

You can install the goExecPy library using the following command:

go get -u github.com/qmdemon/goExecPy

Usage

You can use the Eval method to get the value of an expression, and the Compile method to compile a Python code block and call it. Here's an example:

output, err := execjs.Eval(`"Hello " + "World"`)
if err != nil {
    log.Fatal(err)
}
fmt.Println(output)

When using the Compile method, it is important to ensure that the Python code block is indented correctly.

And here's an example of using the Compile method:

c, _ := execjs.Compile(`
def add(x, y):
    return x + y
`)
output, err := c.Call("add", 1, 2)
if err != nil {
    log.Fatal(err)
}
fmt.Println(output)

More usage examples can be found in the execpy_test.go file.

Please note that the returned value is of type interface{}, so you may need to perform type assertions when using the returned value. For example:

output.(string) //This will convert the value to string type
output.([]interface{}) //This will convert the value to slice type
