How do i get emacs to show a 79 character line limit ? - Skaperen - Oct-08-2016
"Limit all lines to a maximum of 79 characters." lots of my CLI windows are 166 characters wide. but i often edit python files there. i use emacs in a terminal window (the not-X version of emacs). anyone know how to make emacs color the first 79 character spaces (backgrounds) differently? i do not want to be popping up new emacs windows. much of my co already has long lines (easy for me to read).

To change the column limit, customize the variable whitespace-line-column
pdf manual page 83.

what i would prefer to do is have to first 79 or 80 colums set with one background color and the remainder set with another color, like blue for 1-79 and magenta for 80-EOL. the character color should not be affected by this.

If it's not already there, you can do it if you are familiar with lisp.
You can also (I think you can still do this) email Richard Stallman [email protected]
who is (or was) pretty good at responding

i tried lisp many, many years ago. i had to mop up my lunch from the floor. anyone have an emacs implementation in python?

You don't like car, cdr and cons? And don't forget this is where lambda came from.
Actually, I don't remember a whole heck of a lot about lisp, but I recall liking it
a lot back when I used it.
A very simple language that can qet very complex!
Forth is another one, but a beautiful stack oriented interpreted language nonetheless.
don't know of a Python version, but emacs has lisp built in.

i liked forth. but i would have liked a cleaner one more. python is clean :dance: i may, some day in the future, try to make a stack language to play with based on python one way or the other (such as an interpreter written in python or a rewrite of one of the existing python interpreters ... in any case to work in a python context).

I actually just did this last week. Get yourself the column marker lib: https://www.emacswiki.org/emacs/ColumnMarker
Then in your user config, add...
;; add libs to our path (add-to-list 'load-path "~/.emacs.d/lisp/") ;; load the lib (require 'column-marker) ;; add a highlighter to column 79, for python files (add-hook 'python-mode-hook (lambda () () (column-marker-1 79)))
