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?
