;;; Commentary:
|
||||
|
||||
;; Org-Babel support for evaluating Oz source code.
|
||||
;;
|
||||
;; Oz code is always send to the Oz Programming Environment (OPI), the
|
||||
;; Emacs mode and compiler interface for Oz programs. Therefore, only
|
||||
;; session mode is supported. In practice, non-session code blocks are
|
||||
;; handled equally well by the session mode. However, only a single
|
||||
;; session is supported. Consequently, the :session header argument is
|
||||
;; ignored.
|
||||
;;
|
||||
;; The Org-babel header argument :results is interpreted as
|
||||
;; follows. :results output requires the respective code block to be
|
||||
;; an Oz statement and :results value requires an Oz
|
||||
;; expression. Currently, results are only supported for expressions
|
||||
;; (i.e. the result of :results output is always nil).
|
||||
;;
|
||||
;; Expression evaluation happens synchronously. Therefore there is an
|
||||
;; additional header argument :wait-time <number>, which specifies the
|
||||
;; maximum time to wait for the result of a given expression. nil
|
||||
;; means to wait as long as it takes to get a result (potentially wait
|
||||
;; forever).
|
||||
;;
|
||||
;; NOTE: Currently the copyright of this file may not be in a state to
|
||||
;; permit inclusion as core software into Emacs or Org-mode.
|
||||
|
||||
;;; Requirements:
|
||||
|
||||
;; - Mozart Programming System, the implementation of the Oz
|
||||
;; programming language (http://www.mozart-oz.org/), which includes
|
||||
;; the major mode mozart for editing Oz programs.
|
||||
;;
|
||||
;; - StartOzServer.oz which is located in the contrib/scripts
|
||||
;; directory of the Org-mode repository
|
||||
|
||||
;;; TODO:
|
||||
|
||||
;; - Decide: set communication to \\switch -threadedqueries?
|
||||
;;
|
||||
;; - Only start Oz compiler when required, e.g., load Org-babel only when needed?
|
||||
;;
|
||||
;; - Avoid synchronous evaluation to avoid blocking Emacs (complex
|
||||
;; Strasheela programs can take long to find a result..). In order
|
||||
;; to cleanly map code blocks to their associated results (which can
|
||||
;; arrive then in any order) I could use IDs
|
||||
;; (e.g. integers). However, how do I do concurrency in Emacs Lisp,
|
||||
;; and how can I define org-babel-execute:oz concurrently.
|
||||
;;
|
||||
;; - Expressions are rarely used in Oz at the top-level, and using
|
||||
;; them in documentation and Literate Programs will cause
|
||||
;; confusion. Idea: hide expression from reader and instead show
|
||||
;; them statement (e.g., MIDI output statement) and then include
|
||||
;; result in Org file. Implementation: for expressions (:results
|
||||
;; value) support an additional header argument that takes arbitrary
|
||||
;; Oz code. This code is not seen by the reader, but will be used
|
||||
;; for the actual expression at the end. Alternative: feed all
|
||||
;; relevant code as statement (:results output), then add expression
|
||||
;; as extra code block which outputs, e.g., file name (so the file
|
||||
;; name must be accessible by global var), but the code of this
|
||||
;; extra codeblock is not seen. Hm, in that case it might be even
|
||||
;; more easy to manually add this link to the Org file.

|

;; Interface to communicate with Oz.
|
||||
;; (1) For statements without any results: oz-send-string
|
||||
;; (2) For expressions with a single result: oz-send-string-expression
|
||||
;; (defined in org-babel-oz-ResultsValue.el)
|
||||
;;
|
||||
|
||||
;; oz-send-string-expression implements an additional very direct
|
||||
;; communication between Org-babel and the Oz compiler. Communication
|
||||
;; with the Oz server works already without this code via the function
|
||||
;; oz-send-string from mozart.el.in, but this function does not get
|
||||
;; back any results from Oz to Emacs. The following code creates a
|
||||
;; socket for sending code to the OPI compiler and results are
|
||||
;; returned by the same socket. On the Oz side, a socket is opened and
|
||||
;; conected to the compiler of the OPI (via oz-send-string). On the
|
||||
;; Emacs side, a connection to this socket is created for feeding code
|
||||
;; and receiving results. This additional communication channel to the
|
||||
;; OPI compiler ensures that results are returned cleanly (e.g., only
|
||||
;; the result of the sent code is returned, no parsing or any
|
||||
;; processing of *Oz Emulator* is required).
|
||||
;;
|
||||
;; There is no buffer, nor sentinel involved. Oz code is send
|
||||
;; directly, and results from Oz are send back, but Emacs Lisp
|
||||
;; requires a filter function for processing results.
