;;; Commentary:
;; Org-Babel support for evaluating ledger entries.
;;
;; This differs from most standard languages in that
;;
;; 1) there is no such thing as a "session" in ledger
;;
;; 2) we are generally only going to return output from the leger program
;;
;; 3) we are adding the "cmdline" header argument
;;
;; 4) there are no variables
;;; Code:
(require 'ob)
(defvar org-babel-default-header-args:ledger
'((:results . "output") (:cmdline . "bal"))
"Default arguments to use when evaluating a ledger source block.")
(defvar org-babel-ledger-command "ledger"
"Command to invoke ledger")
(defun org-babel-execute:ledger (body params)
"Execute a block of Ledger entries with org-babel. This function is
called by `org-babel-execute-src-block'."
(org-babel-eval
(concat org-babel-ledger-command " " (cdr (assoc :cmdline params)))
body))
(defun org-babel-prep-session:ledger (session params)
(error "Ledger does not support sessions"))
(provide 'ob-ledger)
