I recently switched to mu4e for my mails which is awesome. I changed the date format in the headers view so that it became longer. Unfortunately I cannot see the complete date now because the column width is to small. How can I change this? How can I change the width of all columns? Documentation doesn't mention the column width.


Does customizing mu4e-headers-fields, changing the width corresponding to the :human-date "header", do the job? (I haven't tested this.)

    Thx it worked, I was looking for a documentation on this, but not in the comments of the code ;)

Documentation on how to change headers can be found here : https://www.djcbsoftware.nl/code/mu/mu4e/Longer-configuration.html

Here is the part the op is interested in :

;; the headers to show in the headers list -- a pair of a field
;; and its width, with `nil' meaning 'unlimited'
;; (better only use that for the last field.
;; These are the defaults:
(setq mu4e-headers-fields
    '( (:date          .  25)    ;; alternatively, use :human-date
       (:flags         .   6)
       (:from          .  22)
       (:subject       .  nil))) ;; alternatively, use :thread-subject

Note that the order of the fields in the code will be the same in the view.
