About Form-Fiddle

Often times I need to destructure a form definition in a macro. This is a set of simple utilities to help with that.

How To

There's individual functions to extract each part of a lambda-definition-form: function, name, qualifiers, lambda-list, body, declarations, docstring and the forms. You can get all in one with split-lambda-form, or directly as a binding macro with with-destructured-lambda-form.

(split-lambda-form '(defun lambda-body (lambda-form)
                      (cddr lambda-form)))

(with-destructured-lambda-form (:forms forms)
    '(defmacro foo (bar)
       (declare (ignore bar))
       "Testing macro!"
       (print "test!"))
  forms)

5.1.1 Macros

Macro: with-body-options (BODY OTHER-OPTIONS &rest OPTIONS) FORM &body BODY-FORMS

Destructures the body according to split-body-kargs.

OTHER-OPTIONS will be bound to contain all the options that occur in the body but were not explicitly requested in OPTIONS. BODY will be bound to the remaining body forms. Each option in OPTIONS can be either a symbol or a list of symbol and default. The symbol is automatically converted to a keyword to match against the body options.

Macro: with-destructured-lambda-form (&key FUNCTION NAME QUALIFIERS LAMBDA-LIST DOCSTRING DECLARATIONS FORMS) EXPRESSION &body BODY

Destructures the given EXPRESSION into its lambda-form parts.
