*** mu4e thread folding

[[file:mu4e-thread-folding.el][mu4e-thread-folding.el]] is a small library to enable threads folding in [[https://www.djcbsoftware.nl/code/mu/mu4e.html][mu4e]]. This works by using overlays with an [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Overlay-Properties.html][invisible property]] and setting hooks at the right place. It is possible to configure colors to better highlight a thread and also to have a prefix string indicating if a thread is folded or not. Note that when a thread is folded, any unread child remains visible.

*** Usage

The prefix string is displayed over the header line and it is thus recommended to have an empty field at the start of an header line. Have a look at ~mu4e-headers-fields~.

#+begin_src lisp (require 'mu4e-thread-folding)

(add-to-list 'mu4e-header-info-custom '(:empty . (:name "Empty" :shortname "" :function (lambda (msg) " ")))) (setq mu4e-headers-fields '((:empty . 2) (:human-date . 12) (:flags . 6) (:mailing-list . 10) (:from . 22) (:subject . nil))) #+end_src

*** Keybindings

#+begin_src lisp (define-key mu4e-headers-mode-map (kbd "") 'mu4e-headers-toggle-at-point) (define-key mu4e-headers-mode-map (kbd "") 'mu4e-headers-fold-at-point) (define-key mu4e-headers-mode-map (kbd "<S-left>") 'mu4e-headers-fold-all) (define-key mu4e-headers-mode-map (kbd "") 'mu4e-headers-unfold-at-point) (define-key mu4e-headers-mode-map (kbd "<S-right>") 'mu4e-headers-unfold-all) #+end_src

*** Customization

Options are accessible from the ~mu4e-thread-folding~ customization group.
