currently I'm working a lot with json files. They tend to be a little bigger.
I'm a little fed up with always marking the whole file and then typing M-x json-reformat-region.
Is there a way to do this directly on opening the file?
Regards

I use this hook to achieve an effect like that:
;; pretty print json files when they're opened
(add-to-list 'auto-mode-alist
'("\\.json\\'" . (lambda ()
(javascript-mode)
(json-pretty-print (point-min) (point-max))
(goto-char (point-min))
(set-buffer-modified-p nil))))

Hi I tried it but is not working. I even replaced
json-pretty-printbyjson-reformat-region– daedaCommented Jul 14, 2017 at 19:50 -
Are you getting any errors?– user12563Commented Jul 14, 2017 at 23:23

I don't get any errors, at least no obvious ones that I can see i the minibuffer. Is this for a different mode? I have
json-modeandjson-snatcherinstalled. I open the file and nothings happens...– daedaCommented Jul 16, 2017 at 14:49 -
In that case you might want to add a hook to
json-modethat pretty prints the buffer.– user12563Commented Jul 16, 2017 at 15:19 -
So I finally was able to do this. The problem was that I didn't know to which mode the command
json-reformat-regionbelongs. So here is my adapted version.;; pretty print json files when they're opened (add-to-list 'auto-mode-alist '("\\.json\\'" . (lambda () (json-mode) (json-reformat-region (point-min) (point-max)) (goto-char (point-min)) (set-buffer-modified-p nil))))– daedaCommented Jul 18, 2017 at 20:43
