Subject: fill-column setq-default and add-hook
Date: Sat, 30 Nov 2024 17:38:15 +0000	[thread overview]
Message-ID: <F5jffkEwtQo2yAD8pQLvxBMlkpwdtJC1PVzhOwpBpXMy19X9b3gPUu-lNyRjQTQrwkNWJVQcpxF9jYrtF5j1TIh_7woQ88pGNsxEa5nXnLE=@protonmail.com> (raw)



I want to understand the setting of fill-column.  It is a buffer local variable.  

But then there the following possibilities 

   (setq-default fill-column 72)

and       

   (add-hook 'prog-mode-hook  (lambda () (setq fill-column 72)))

The first sets fill-column globally.  What does that mean?  I interpret
that the value is set globally but only to those buffers for which there
is no local binding.  This setting the value (setq-default fill-column 72)
does not always work for the current buffer.  How can one solve this problem?

What does the mode hook do exactly?
