case *ast.ArrayType:
return "array type"
case *ast.AssignStmt:
return "assignment"
case *ast.BlockStmt:
return "block"
...
}
Example 2:
var node ast.Node
...
switch n := node.(type) {
var stmt := n.Else.(type)
block := &ast.BlockStmt{
Lbrace: n.Body.End(), // Start at end of the "if" block so the covered part looks like it starts at the "else".
List: []ast.Stmt{stmt},
Rbrace: stmt.End(),
}
n.Else = block
}
...
