How Can I Dynamically Retrieve Function Names in Go?

Retrieving Function Names Dynamically in Go

In Go, determining the name of a given function can be beneficial for debugging, logging, and other scenarios. This article demonstrates how to achieve this functionality using the runtime.FuncForPC package.

The provided code example defines a function foo and a function GetFunctionName that takes an interface and returns the function name as a string.

Let's break down the GetFunctionName function:

1. We pass the reflect.ValueOf(i).Pointer() to runtime.FuncForPC to obtain a Func object.
2. The Name() method of the Func object retrieves the name of the function.

By following this approach, you can successfully extract the name of a given function in Go. This capability can be useful in various situations and enhances the transparency and control over your codebase.
