default-fill-column is gone

default-fill-column is gone

[Uwe Brauer]

Hi

I just upgraded to GNU emacs 27.

Now I admit that I package which is a bit hm old, feedmail.

Now feedmail uses default-fill-column which in 27 does not exist 
any more. I found this entry in ChangeLog.3
2016-11-07  Mark Oteiza  <mvoteiza@udel.edu>  Remove obsolete 
default-FOO variables  * etc/NEWS: Indicate the removed variables. 
* lisp/emacs-lisp/edebug.el (edebug-outside-mark): Fix comment.  * 
lisp/subr.el (default-mode-line-format, * 
default-header-line-format): (default-fill-column, 
default-cursor-type): (default-enable-multibyte-characters): 
Remove obsolete declarations. 

So there is no hint how to deal with this situation. Why couldn't 
variables be kept or at least some solution to be offered to 
guarantee backwards compatibility. For example which variables 
substitute default-fill-column, I presume it is fill-column. Since 
I use different emacs version but the same init file, for the 
moment I will add

(cond ((>= emacs-major-version 27) 
       (setq default-fill-column fill-column))) 



below you find the error message

Debugger entered--Lisp error: (void-variable default-fill-column) 
  eval(default-fill-column) 
  custom-initialize-reset(feedmail-fill-to-cc-fill-column 
  default-fill-column) 
  custom-declare-variable(feedmail-fill-to-cc-fill-column 
  default-fill-column "*Fill column used by feedmail-fill-to-cc." 
  :group feedmail-headers :type integer)

Those variables were marked obsolete in 23.2, which is 8 years ago.

Also, I guess this means you're not using the feedmail that ships with
Emacs, which uses fill-column instead of default-fill-column.

Oops, but the entry I referred to was from 2016, anyhow.

Ah good to know, I will give this version then a try.

Thanks

That's when they were finally removed, yes.

M-x list-load-path-shadows perhaps?
