How to Retrieve All Structs within a Go Package?

Retrieving All Structs within a Go Package

In Go, it is possible to enumerate all structures defined within a specific package. To accomplish this, the most efficient solution involves parsing the Go source files, extracting the abstract syntax tree (AST), and isolating the ast.StructType instances.

The hg command can be utilized to clone the Go sources:

hg clone https://code.google.com/p/go/

Subsequently, you can isolate the ast.StructType instances by parsing the source files. Here is an example provided by the linter go/lint that demonstrates how to extract struct field names:

    case *ast.StructType:
        for _, f := range v.Fields.List {
            for _, id := range f.Names {
                check(id, "struct field")
            }
        }

By parsing the AST and extracting the ast.StructType instances, you can obtain a list of all structures within the specified package.
