Yes I want to create a modification to Emacs Lisp code to specify a

all I need to do is load "accounts.beancount" and then when I'm
editing any specific transactions file I have access to type-ahead for
any of the accounts found in accounts.beancount.
I'm not yet comfortable with Emacs Lisp. I'll try to figure it out but
if anyone knows how to do this modification easily that would save me
a lot of time and perhaps be generally useful as I think there are
others who split up their beancount data among multiple files.
Jonathan,
Here is a second approach.
If you are planning on doing a lot of manual entry, you might want the
autocompletion to "just work" in the mode (with <TAB> or whatever).
In that case, my first try is not going to be ideal (invoking a
function every time, even with a keybinding).
First I started thinking about modifying beancount-collect function,
until I realized that is a general function called from many different
places. So instead I think we need to try modifying the
beancount-account-completion-table function.
Note that this is completely untested code, but give this a whirl:
#+begin_src emacs-lisp
;; Define variable
(defvar my-beancount-accounts-file nil
"Full path to beancount accounts file.")
;; (Re-)Define function
;; N.B. this must go AFTER (require 'beancount) in your init
;; file, as we are re-defining the function.
(defun beancount-account-completion-table (string pred action)
(if (eq action 'metadata) '(metadata (category . beancount-account))
(if (null beancount-accounts)
(setq beancount-accounts
(save-current-buffer
(find-file-noselect my-beancount-accounts-file)
(set-buffer (file-name-nondirectory
my-beancount-accounts-file))
(sort (beancount-collect beancount-account-regexp 0)
#'string<))))
(complete-with-action action beancount-accounts string pred)))
;; Set variable
(setq my-beancount-accounts-file "/path/to/your/accounts.beancount")
#+end_src
Essentially we inserted a call to open (if it's not already) your
accounts file in a background buffer, execute the search over there,
and then return to current position.
Let me know if it works.
Cheers,
TRS-80
