Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

;; 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 ledger 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.")
|
|
|
|
(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'."
