How to Obtain a List of All Structs within a Package in Golang?

Obtaining All Structs within a Package in Golang

You can enumerate all structs within a package by accessing their AST representation. One approach is to parse the package source code, which requires cloning the Go repository and extracting the relevant data.

The code below outlines how to achieve this using the AST parser:

<code class="go">func (P *Printer) Type(t *AST.Type) int {
    separator := semicolon;

    switch t.form {

    case AST.STRUCT, AST.INTERFACE:
            switch t.form {
            case AST.STRUCT: P.String(t.pos, "struct");
            case AST.INTERFACE: P.String(t.pos, "interface");
            }
            if t.list != nil {
                    P.separator = blank;
                    P.Fields(t.list, t.end);
            }
            separator = none;
    }
}</code>

Another example from Go's linter illustrates a similar approach:

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

By traversing the AST representation, you can collect information about all structs within a particular package, providing you with the list of desired names or interfaces.
