(in-package :swank)
|
|
|
|
;; this file is empty of functionality. The slime-media contrib
|
|
;; allows swank to return messages other than :write-string as repl
|
|
;; results; this is used in the R implementation of swank to display R
|
|
;; objects with graphical representations (such as trellis objects) as
|
|
;; image presentations in the swank repl. In R, this is done by
|
|
;; having a hook function for the preparation of the repl results, in
|
|
;; addition to the already-existing hook for sending the repl results
|
|
;; (*send-repl-results-function*, used by swank-presentations.lisp).
|
|
;; The swank-media.R contrib implementation defines a generic function
|
|
;; for use as this hook, along with methods for commonly-encountered
|
|
;; graphical R objects. (This strategy is harder in CL, where methods
|
|
;; can only be defined if their specializers already exist; in R's S3
|
|
;; object system, methods are ordinary functions with a special naming
|
|
;; convention)
