Definitions are sorted by export status, category, package, and then by lexicographic order.


5.1 Public Interface


5.1.1 Macros

Macro: defclass (name direct-superclasses direct-slots &rest options)

Define Modf expansions for class slot accessor and reader methods.

Package

modf-def.

Source

modf-def.lisp.

Macro: define-modf-expander (name nth-arg (expr val new-val) &body body)

Define a new expander which inverts forms starting with NAME. Your function should return an expansion from EXPR to a form that will build a new object that has NEW-VAL in the place specified by expr. NTH-ARG marks which argument is considered the actual data which will be inverted next.

Package

modf.

Source

modf.lisp.

Macro: define-modf-for-class-slots (class-name-or-definition)

This macro defines Modf expanders for a class. We can do this given the definition form for the class (much like with DEFINE-MODF-FOR-STRUCT-SLOTS) or the a name of a finalized class.

Package

modf-def.

Source

modf-def.lisp.

Macro: define-modf-for-struct-slots (structure-definition-form)

This macro defines Modf expanders for structure slots when given a structure definition form.

Package

modf-def.

Source

modf-def.lisp.

Macro: define-modf-function (name nth-arg (new-val &rest args) &body body)

Define a new modf function. It inverts NAME forms by modifying the NTH-ARG term of the arguments of the place form in the MODF macro.

Package

modf.

Source

modf.lisp.

Macro: define-modf-method (name nth-arg (new-val &rest args) &body body)

Define a new modf method. It inverts NAME forms by modifying the NTH-ARG term of the arguments of the place form in the MODF macro. This method can specialize on any of ARGS.

Package

modf.

Source

modf.lisp.

Macro: define-modf-rewrite (name (expr) &body body)

Define a new rewrite rule. If a form starting with NAME is encountered, call the defined function to return a form that we can deal with (i.e. one defined via DEFINE-MODF-EXPANDER, DEFINE-MODF-FUNCTION, and DEFINE-MODF-METHOD).

Package

modf.

Source

modf.lisp.

Macro: defstruct (name-and-options &rest slot-descriptions)

Define a new structure with Modf expansions for slots.

Package

modf-def.

Source

modf-def.lisp.

Macro: fsetf (place value &rest more)
Package

modf.

Source

modf.lisp.

Macro: modf (place value &rest more)

Make a new object (which may use some of the old object) such that PLACE evaluates to VALUE.

MORE should have the form...

MORE : NIL
| (TEMPORARY-BINDING ANOTHER-MODF-PLACE ANOTHER-VALUE . MORE)

Use it to specify a temporary binding for the new object created which will be used in the subsequence MODF-PLACE NEW-VALUE pairs until the end of the MODF form.

Package

modf.

Source

modf.lisp.

Macro: modf-eval (&rest args)
Package

modf.

Source

modf.lisp.

Macro: modf-fn (symbol)

Expand to the defined Modf function. Basically, (MODF-FN SYM) is the functional analog of #’(SETF SYM).

Package

modf.

Source

modf.lisp.

Function: late-class-reader-inverter (func new-val obj)
Package

modf.

Source

modf.lisp.

Function: late-invert (func new-val obj &rest args)

This is a generic catch as much as you can function. It attempts to identify class accessor functions, structure accessor functions, and provides late MODF defined functions (i.e. you used MODF before using DEFINE-MODF-FUNCTION).

All of this functionality is less than ideal efficiency wise, but working over efficiency any day, right? If you want better performance, define all of you functions ahead of time.
