Hi,
Thought it would be handy to be able to do this:
#+STARTUP: truncate
and
#+STARTUP: notruncate
Modifying org-startup-options manually wouldn't work as it describes how to
change a value of a variable or push onto a list, but no syntax for
function calls and for this to work toggle-truncate-lines is to be envoked.
I know about org-startup-truncated, but it's not file-by-file precision.
PS if this turns out to be hairy, I can use .dir-locals.el, but the feature
would still be a nice-to-have.
Regards,
Dmitrii

You could use file local variables for this, e.g.
# Local Variables:
# truncate-lines: t
# End:
at the end of your org file or
# -*- truncate-lines: t; -*-
as the first line of your file.
This is not org specific so I guess there is no real justification for
an org variable for this feature.

This works nicely, thank you! Never knew about these.
By the way, I got the STARTUP to function. Turns out it's enough to set
truncate-lines variable and the change is picked up automatically (docs
say: "Calls these functions when changed: (#<subr set-buffer-redisplay>)").
Here is the code shall someone need it:
(eval-after-load 'org
(lambda ()
(setq org-startup-truncated nil)
(push (list "truncate" 'truncate-lines t) org-startup-options)
(push (list "notruncate" 'truncate-lines nil) org-startup-options)))
Note that (setq org-startup-truncated nil) is needed for the notruncate
option to work. Plus the stuff in the org-mode-hook runs after the STARTUP
lines, so beware that it can also cause interference.
Thanks all!

And just not to leave the bad code be, here is a different, better way:
(setq my/org-truncate-option nil)
(eval-after-load 'org
(lambda ()
(push (list "truncate" 'my/org-truncate-option 1) org-startup-options)
(push (list "notruncate" 'my/org-truncate-option -1)
org-startup-options)))
And in org-mode hook:
(lambda () (case my/org-truncate-option (1 (setq truncate-lines t)) (-1
(setq truncate-lines nil))))
this avoids interference w/ org-startup-truncated while giving flexibility
to conditionally set truncation in .dir-locals.el and STARTUP will always
work.
