Tricks

Vertical rulers on a specific column

Setup a Ruler on a Specific Column in Vim | Baeldung on Linux

In python's PEP 8, the maximum line length is limited to 79 (and docstrings/comments to 72). So a vertical indication line is necessary.

You can add a vertical ruler by typing:

:set colorcolumn=72,80

The line's color can be adjusted, ctermbg for vim called from terminal while guibg for vim called from GUI (which is gvim)

:highlight colorcolumn ctermbg=lightgrey guibg=lightgrey

The two lines can be added to ~/.vimrc for automatic loading. (The # shall be removed.)

#set colorcolumn=72,80
highlight colorcolumn ctermbg=lightgrey guibg=lightgrey
