;;; Commentary:
|
|
|
|
;; This library enables the use of PicoLisp in the multi-language
|
|
;; programming framework Org-Babel. PicoLisp is a minimal yet
|
|
;; fascinating lisp dialect and a highly productive application
|
|
;; framework for web-based client-server applications on top of
|
|
;; object-oriented databases. A good way to learn PicoLisp is to first
|
|
;; read Paul Grahams essay "The hundred year language"
|
|
;; (http://www.paulgraham.com/hundred.html) and then study the various
|
|
;; documents and essays published in the PicoLisp wiki
|
|
;; (http://picolisp.com/5000/-2.html). PicoLisp is included in some
|
|
;; GNU/Linux Distributions, and can be downloaded here:
|
|
;; http://software-lab.de/down.html. It ships with a picolisp-mode and
|
|
;; a inferior-picolisp-mode for Emacs (to be found in the /lib/el/
|
|
;; directory).
|
|
|
|
;; Although it might seem more natural to use Emacs Lisp for most
|
|
;; Lisp-based programming tasks inside Org-Mode, an Emacs library
|
|
;; written in Emacs Lisp, PicoLisp has at least two outstanding
|
|
;; features that make it a valuable addition to Org-Babel:
|
|
|
|
;; PicoLisp _is_ an object-oriented database with a Prolog-based query
|
|
;; language implemented in PicoLisp (Pilog). Database objects are
|
|
;; first-class members of the language.
|
|
|
|
;; PicoLisp is an extremely productive framework for the development
|
|
;; of interactive web-applications (on top of a database).
