I'm attempting what should be a simple transformation using a macro
called dlg in the following code:
(defn fld [parent lay id text field]
'...)
;; dlg macro. For this input:
;;
;; (dlg "test"
;; (field fld-1 "Field number one" (JTextField.))
;; (field fld-2 "Field number two" (JTextField.)))
;;
;; we want this output:
;;
;; (fn [parent layout]
;; (fld parent layout 'fld-1 "Field number one" (JTextField.))
;; (fld parent layout 'fld-2 "Field number two" (JTextField.))
;; parent)
(defmacro dlg [dlgid# & fields#]
`(fn [parent# layout#]
~@(map
(fn [[f# id# text# type#]]
`(fld parent# layout# '~id# ~text# ~type#))
fields#)))
(def inp '(dlg "test"
(field fld-1 "Field number one" (JTextField.))
(field fld-2 "Field number two" (JTextField.))))
(macroexpand inp)
;; =>
;; (fn* ([parent__6 layout__7]
;; (user/fld parent__4 layout__5 (quote fld-1) "Field number
one" (JTextField.))
;; (user/fld parent__4 layout__5 (quote fld-2) "Field number
two" (JTextField.))))
(eval inp)
;; =>
;; java.lang.Exception: Unable to resolve symbol: parent__4 in this
context (NO_SOURCE_FILE:24)
I'm wondering why the macro produces 2 different "parent" symbols--I'd
like both references to be the same parent. Any suggestions?
