func FirstEnclosing ¶

func FirstEnclosing[N ast.Node](cur inspector.Cursor) (N, inspector.Cursor)

FirstEnclosing returns the first value from [cursor.Enclosing] as both a designated type and a inspector.Cursor pointing to it.

It returns the zero value if it is not found.

A common usage is:

call, callCur := cursorutil.FirstEnclosing[*ast.CallExpr](cur)
if call == nil {
	// Not Found
}

func Path ¶

func Path(cur inspector.Cursor) (path []ast.Node)

Path returns the specified node followed by all its ancestors up to the file. Use it as an adaptor between cursors and code that works with PathEnclosingInterval. Ultimately all such code should be eliminated.
