This is used to choose between a function form or a value form of the place.
default-form can be a function name or "something" more complex.
Hierarchical getx. You dont really need to
create specializers based on the type of place because
digx uses getx internally and getx does the type specific work.
Examples:
> (digx (list :eish (list :huh 1)) :eish :huh)
1
> (let ((x (list :eish (list :huh 1))))
(setf (cl-getx:digx x :eish :huh) ’huh)
x)
(:EISH (:HUH HUH))
Returns the data stored in a place by name or named-accessor or concrete accessor function.
Currently places, hash-tables and plists are implemented. Methods for specific types or other lisp types can be implemented easially.
Examples:
> (getx (list :eish 1) :eish)
1
> (getx (list ’eish 1) ’eish)
1
> (getx (list ’eish 1) #’(lambda (place) (getf place ’eish)))
1
(defclass thingy () ((eish :initarg :eish :accessor eish)))
(setf x (make-instance ’thingy ’eish 1))
> (getx x ’eish)
1
**EXTREME**
Or if you really want uniform thinking and syntax for your data places
This is not a good idea if you are writing a library that others will use
some one might clobber your :eish by accident or you might clobber their :eish
(defclass thingy () ((eish :initarg :eish :accessor :eish)))
(setf x (make-instance ’thingy :eish 1))
> (getx x :eish)

Specialize as you need. plists, hash-tables and standard-object is taken care of.
standard-object) accessor &key &allow-other-keys) ¶This is for use with (setf getx) of standard-objects.
hash-table) accessor &key default &allow-other-keys) ¶This is for use with (setf getx) of gethash.
list) accessor &key &allow-other-keys) ¶This is for use with (setf getx) of gethash.
Returns t if the place exists. Default implementation is for plists.
standard-object) slot-name) ¶This is a bit of a waste to do since gethash gives you the value and tells you if the key is not found, but its here for completeness.
hash-table) key) ¶This is a bit of a waste to do since gethash gives you the value and tells you if the key is not found, but its here for completeness.
