+
+;;; Commentary:
+
+;; ob-vala.el provides Babel support for the Vala language
+;; (see http://live.gnome.org/Vala for details)
+
+;;; Requirements:
+
+;; - Vala compiler binary (valac)
+;; - Vala development environment (Vala libraries etc.)
+;;
+;; vala-mode.el is nice to have for code formatting, but is not needed
+;; for ob-vala.el
+
+;;; Code:
+
+(require 'ob)
+
+(declare-function org-trim "org" (s &optional keep-lead))
+
+;; File extension.
+(add-to-list 'org-babel-tangle-lang-exts '("vala" . "vala"))
+
+;; Header arguments empty by default.
+(defvar org-babel-default-header-args:vala '())
+
+(defcustom org-babel-vala-compiler "valac"
+ "Command used to compile a C source code file into an executable.
+May be either a command in the path, like `valac'
+or an absolute path name, like `/usr/local/bin/valac'.
+Parameters may be used like this: `valac -v'"
+ :group 'org-babel
+ :version "24.3"
+ :type 'string)
+
+(defun org-babel-expand-body:vala (body params &optional processed-params)
+ "Expand BODY: does nothing, returns original BODY while ignoring PARAMS."
+ body ;; TODO: expand params?
+ )
+
+;; This is the main function which is called to evaluate a code
+;; block.
+;;
+;; - run Vala compiler and create a binary in a temporary file
+;; - compiler/linker flags can be set via :flags header argument
+;; - if compilation succeeded, run the binary
+;; - commandline parameters to the binary can be set via :cmdline
+;; header argument
+;; - stdout will be parsed as RESULT (control via :result-params
+;; header argument)
+;;
+;; There is no session support because Vala is a compiled language.
+;;
+;; This function is heavily based on ob-C.el
