Can you try adding the following to your .emacs?
(package-initialize)
(require 'ledger-mode)
(defun ledger-accounts-deduplicate-sorted (l)
"Remove duplicates from a sorted list of strings L."
(let ((current l))
(while (consp current)
(if (string= (car current) (cadr current))
(setcdr current (cddr current))
(pop current)))
l))
(defun ledger-accounts-list-in-buffer ()
"Return a list of all known account names in the current buffer as strings.
Considers both accounts listed in postings and those declared with \"account\"
directives."
(save-excursion
(goto-char (point-min))
(let (results)
(while (re-search-forward ledger-account-name-or-directive-regex nil t)
(setq results (cons (match-string-no-properties 2) results)))
(ledger-accounts-deduplicate-sorted
(sort results #'ledger-string-greaterp)))))
This patches ledger-accounts-list-in-buffer to use a linear-time deduplication
(rather than quadratic).
Clément.
