Hello, small intro in case there is a better way than I thought up: I've just started using Ledger and wanted to use Babel to tangle the ledger file.
Every entry is its own heading: * <2016-07-01 Fri> * Hollywood | Monthly rent #+begin_src ledger :tangle yes 07-01 * Hollywood | Monthly rent Expenses:Rent 500.00 USD Expenses:Rent:Parking spot 50.00 USD Assets:BOA:Checking #+end_src I've written a function to basically do what I want: (defun org-header-to-ledger (&optional point) (save-excursion (re-search-backward org-ts-regexp) (let* ((context (org-element-context)) (year (org-element-property :year-start context)) (month (org-element-property :month-start context)) (day (org-element-property :day-start context)) (title (cadr (split-string (org-element-property :title (org-element-property :parent context)) (rx (or "]" ">")))))) (format "%04d-%02d-%02d%s" year month day title)))) ;; (There are known bugs but for illustraton purposes this is suitable) Now in babel I would basically want to not have repeated data, so my entry should look like this: * <2016-07-01 Fri> * Hollywood | Monthly rent #+begin_src ledger :tangle yes <<elisp:org-header-to-ledger>> Expenses:Rent 500.00 USD Expenses:Rent:Parking spot 50.00 USD Assets:BOA:Checking #+end_src The actual syntax is not that important, but something to that effect so I only have to keep one headline up to date is what I'm looking for. Is there a way to accomplish this right now? If there isn't, can you point me to where I would add such functionality? AFAIK named src block can already be inserted, I just don't know where in the source that is found. Thanks in advance and best regards, Benny
