Setting fill-column and others for text-mode

Setting fill-column and others for text-mode

[Decebal]

I would like to set fill-column, left-margin, tab-width and default-
justification for text-mode, but I do not manage to get this working.
How can this be done?

You can set them inside a hook like this:
(setq fill-column 70)

You already know how to do hooks.

It has to be:
    (setq-default fill-column 72)

For fill-column and tab-width I thought it better to do it globally.

I also use:
    (add-hook 'text-mode-hook (lambda () (refill-mode 1) (setq-default
default-justification 'full)))
    (add-hook 'org-mode-hook  (lambda () (refill-mode 0) (setq-default
default-justification 'left)))

But this only works partly. Refill-mode is t for text-mode and  nill
for or-mode, but default-justification is for both full. What is going
wrong here?

I also tried:
    (add-hook 'org-mode-hook  (lambda () (refill-mode 0)))
    (add-hook 'org-mode-hook  (lambda () (setq-default default-
justification 'left)))

But with the same result.

And I would prefer something like:
    (defun text-justification ()
      (interactive)
      (refill-mode 1)
      (setq-default default-justification 'full)
      )

    (defun text-no-justification ()
      (interactive)
      (refill-mode 0)
      (setq-default default-justification 'left)
      )

    (add-hook 'text-mode-hook 'text-justification)
    (add-hook 'org-mode-hook  'text-no-justification)

Can something like this be done?

You hit a documentation barrier in space-time. The doc string for
org-mode simply does not tell you some essential things:

- org-mode is made by define-derived-mode from outline-mode
- outline-mode is similar made from text-mode
- the mode hooks from the ancestor modes are run before the mode hook

In this case it means that when you turn on org-mode then the
following hooks are run at the end by run-mode-hooks, in this order:

   text-mode-hook, outline-mode-hook, org-mode-hook

This (together with how setq-default works) can probably explain what you see.

I think I can best disable the hook and just execute text-
justification.

I have defined the folowing functions (and removed the add-hook) and
this seems to work:
(defun text-justification ()
  (interactive)
  (refill-mode 1)
  (setq-default default-justification 'full)
  )

(defun text-no-justification ()
  (interactive)
  (refill-mode 0)
  (setq-default default-justification 'left)
  )

Is there otherwise a possibility to execute text-justification only on
functions ending with (for example) .txt?

Look at the hooks in Emacs manual. There is an `after-change-major-mode-hook'.

BTW it would be nice if someone made a summary of all the hooks run
when opening a file.

What is going on here is that you explicitly set the global value of
default-justification by using setq-default, which means it affects all
buffers in all modes.  The value that you are seeing depends upon which
hook was run most recently.

Just use normal setq instead of setq-default.
