When searching files with projectile, I get some results several times. https://infinit.io/_/uHRFe6P Has anyone the same problem as me ?

not me

@lowl4tency: you shouldn’t use defconst to change variables

bozhidar: hm, it's working better than default

as for the let examples

I meant you should use setq

defconst is for constant definition...

anyways, not idea what you want to do with the let bindings

I’m assuming you want to change the indentation level just in some particular scope

in which case the second let should work

dynamically tweaking indentation doesn’t seem reasonable to me, but as I said - I have no idea what you’re trying to do

Okay, let me describe, I'd like to change indentation level from default 4 to 2 spaces. In docs author suggests to change it via json-reformat, but when I change it, it doesn't work at all.

json-reformat:indent-width (integer)

    Change indentation level (default 4)

if I set up next:

(defcustom json-reformat:indent-width 2
  "How much indentation `json-reformat-region' should do at each level."
  :type 'integer
  :safe #'integerp
  :group 'json-reformat)

If I set defconst it's working

you should do (setq json-reformat:indent-width 2)

that’s the proper way to modify a defcustom

bozhidar: thanks!

Actually, I've started read elisp reference, and now it's more clear for me

bozhidar: one more stupid q, when is appropriated to use defconst?

;;;###autoload
(setq js-indent-level 2)
(defun json-mode-beautify ()
  "Beautify / pretty-print the active region (or the entire buffer if no active region)."
  (interactive)
  (let ((json-reformat:indent-width js-indent-level ))
    (if (use-region-p)
        (json-reformat-region (region-beginning) (region-end))
      (json-reformat-region (buffer-end -1) (buffer-end 1)))))

(define-key json-mode-map (kbd "C-c C-f") 'json-mode-beautify)

Works!

@lowl4tency: when you have to define a constant, of course

😄

js-indent-level is not const?

most likely it’s a defcustom

a variable customizable via the customize UI

ah, okay

see https://www.gnu.org/software/emacs/manual/html_node/elisp/Defining-Variables.html

bozhidar: thanks a lot, I guess I must read specs of elisp before asking )

never a bad idea

😄

I love emacs, it inspires me

we all do - it’s the single greatest piece of software ever created

totally agreed!
