I want to have the variable find-file-hooks set so that when I find a file, the buffer automatically gets set to truncate-line mode. I tried something like (setq find-file-hooks 'set-variable truncate-lines t) and various other permutations with more quotes and parens, but i just got weird erros (sequencep error, or error in init file, or wrong argument type.) is it obvious that i know no lisp? Can somebody give me the magic incantation? jt

I tried >something like > >(setq find-file-hooks 'set-variable truncate-lines t) Find-file-hook's documentation (available via Ctrl-H V) says that it is a "list of functions..." So the syntax would be: (setq find-file-hooks '(func1 func2)) Where func1 and func2 are functions (written by you or someone else) which take no arguments. So you could do: (defun set-truncate-lines () (setq truncate-lines t)) and sub "set-truncate-lines" for "func1 func2" above. Or to really wow you're friends, define an "anonymous" function using a lambda expression: (setq find-file-hooks '((lambda () (setq truncate-lines t)))) [For more information on lambda expressions, see _Practical_Jokes_Played on_the_LISP_Community_ by Guy Steele.] But I don't think this is what you want. This hook is for >making something happen< each time a file is loaded. What you want is >for something to be true< all the time. (Right?) The setq-default function is designed for this porpoise. (See the documentation available via Ctrl-H F.) Put the following in your .emacs file: (setq-default truncate-lines t) Thus all buffers which don't explicitly have the value of truncate-lines set will use the default value.
