Macro DEF

Syntax:

General form:

  def what name &rest definition-forms
  => <undefined>

Special definer form:

  def definer what (&key type-of-naming-form name body-name) &body definer-forms
  => <undefined>

Arguments and Values:

Simple DEF form:

what---a symbol, a cons, or the symbol definer

name---a symbol or a cons

definition-forms---a compound form

Special DEF DEFINER form:

what---a symbol, a cons, or the symbol definer

type-of-naming-form---the symbol symbol, or the symbol cons (or some other type specifier); the default is SYMBOL

name---a symbol that is used within the body definer-forms to retrieve the name of the object being defined; the default is the symbol name



  body-name---a symbol that is used
  within the body definer-forms to retrieve the
  actual definition forms for the definer; the default is the symbol
  definition-forms

  definer-forms---a compound form


  Description:

  Calls the appropriate  CL definition form, or a user
  definition form built by a specialized call to BUILD-DEFINITION-FORM.
  

  what is a symbol or a cons which directs the
  underlying form builder code in a method of
  BUILD-DEFINITION-FORM to produce the appropriate
  result.

  name is a symbol or a cons which can be
  processed to produce the actual name of the obejct being
  defined.

  The actual contents of definition-forms depend on
  what is being defined.


  Using the definer indicator

  what can be the predefined symbol
  definer. In this case the DEF macro
  behaves as follows. A BUILD-DEFINITION-FORM
  method on name is defined.  The keyword
  parameters that can be passed to the DEF are meant to ease the
  writing of
  definer-forms.

  

  type-of-naming-form is used in a DECLARE form to
  aid the compiler. name-var is a symbol that is used
  within the body definer-forms to retrieve the
  name of the object being
  defined. body-name is a symbol that is used
  within the body definer-forms to retrieve the
  actual definition forms for the definer.




  Examples:

  See the main page.


  Side Effects:

  name is defined as a what
  in the environment.  what is defined depends on
  the current set of methods for the generic function
  BUILD-DEFINITION-FORM.
  


  Affected By:

  None.


  Exceptional Situations:

  Environment dependent.
