How to Retrieve a List of Structures Within a Go Package?

Obtaining a List of Structures in a Go Package

Determining a comprehensive list of structures within a package in Go can be achieved through various methods. While there is no straightforward function such as list("fmt") to retrieve the structures directly, there are approaches that can provide insights into the package's structure:

One solution lies in parsing the Go source code. By cloning the Go source repository, you can access the AST (Abstract Syntax Tree) of the package. This AST contains information about the structures present, allowing you to isolate the relevant ast.StructType nodes. This approach mirrors the behavior of pretty printers, which extract this information for presentation purposes.

Another method involves using the go/lint package. The lint tool performs analysis on Go code and includes support for identifying structures. By inspecting the code within the package, go/lint can detect and display the structure names, providing a list of structures as part of its output.

It's important to note that these approaches require some degree of programmatic parsing and manipulation of the source code. However, they offer a flexible and comprehensive way to obtain information about the structures in a Go package.
