;;; Commentary:
;; Org-Babel support for evaluating hledger entries.
;;
;; Based on ob-ledger.el.
;; If the source block is empty, hledger will use a default journal file,
;; probably ~/.hledger.journal (it may not notice your $LEDGER_FILE env var).
;; So make ~/.hledger.journal a symbolic link to the real file if necessary.
;;; Code:
(require 'ob)
(defvar org-babel-default-header-args:hledger
'((:results . "output") (:exports . "results") (:cmdline . "bal"))
"Default arguments to use when evaluating a hledger source block.")

called by `org-babel-execute-src-block'."
