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 , 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. -;; - - -(require 'ob) -;;; major mode for editing Oz programs -(require 'mozart) - -;; -;; 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. - -(defvar org-babel-oz-server-dir - (file-name-as-directory - (expand-file-name - "scripts" - (file-name-as-directory - (expand-file-name - "../../.." - (file-name-directory (or load-file-name buffer-file-name)))))) - "Path to the contrib/scripts directory in which -StartOzServer.oz is located.") - -(defvar org-babel-oz-port 6001 - "Port for communicating with Oz compiler.") -(defvar org-babel-oz-OPI-socket nil - "Socket for communicating with OPI.") - -(defvar org-babel-oz-collected-result nil - "Aux var to hand result from org-babel-oz-filter to oz-send-string-expression.") -(defun org-babel-oz-filter (proc string) - "Processes output from socket org-babel-oz-OPI-socket." -;; (setq org-babel-oz-collected-results (cons string org-babel-oz-collected-results)) - (setq org-babel-oz-collected-result string) - ) - - -(defun org-babel-oz-create-socket () - (message "Create OPI socket for evaluating expressions") - ;; Start Oz directly - (run-oz) - ;; Create socket on Oz side (after Oz was started). - (oz-send-string (concat "\\insert '" org-babel-oz-server-dir "StartOzServer.oz'")) - ;; Wait until socket is created before connecting to it. - ;; Quick hack: wait 3 sec - ;; - ;; extending time to 30 secs does not help when starting Emacs for - ;; the first time (and computer does nothing else) - (sit-for 3) - ;; connect to OPI socket - (setq org-babel-oz-OPI-socket - ;; Creates a socket.
