* Description
This layer integrates a full fledged accounting system into Spacemacs.

** Features:
- Support for maintaining a double-entry accounting system run by text files via [[https://www.emacswiki.org/emacs/LedgerMode][ledger-mode]].
- Display of finance reports directly within emacs.
- Integration of emacs calculator mode for editing post amounts.
- Support for easy account reconciliation via =Ledger-Reconcile=.
- Extended support for ~evil~ style editing with [[https://github.com/atheriel/evil-ledger][evil-ledger]].

* Install
** Layer
To use this configuration layer, add it to your =~/.spacemacs=. You will need to
add =finance= to the existing =dotspacemacs-configuration-layers= list in this
file.

For this layer to work properly you also need to install the native package [[https://github.com/ledger/ledger][ledger]].

* Configuration
** Ledger
You can set what column transaction posts are aligned to on
the right by setting the variable =ledger-post-amount-alignment-column= in
your =dotspacemacs/user-config=. The default value, set in the layer, is =62=.

#+BEGIN_SRC emacs-lisp
  (defun dotspacemacs/user-config ()
    (setq ledger-post-amount-alignment-column 68))
#+END_SRC
