It seems the standard doc package is not parsing go:generate comments. Any idea how can I get those comments?
Package go/parser in the standard library gets you an ast.Package value, representing an abstract syntax tree of a single package. This tree includes ast.Comment nodes, whose textual content you can easily access through their Text field.
Edit:
Dewy Broto contributed: A more direct option is to call the go/scanner package with the ScanComments flag set to true. There's no need to build an AST to find the comments
