Subject: Macro expansion: Why doesn't the invoked macro see (let (variables)) from the invoking one?
Date: Wed, 8 Feb 2012 17:26:38 +0000 [thread overview]
Message-ID: <20120208172638.GB3523@acm.acm> (raw)
Hello, Emacs.
One macro FOO binds a let variable, then invokes another macro BAR. BAR
doesn't see this let variable. Why not? Is there anything I can do
about this?
(defmacro BAR ()
(message (if (boundp 'asdf) "asdf" "no asdf"))
'(message "bar"))
(defmacro FOO ()
(let (asdf)
`(BAR)))
