How can I show vertical indentations markers with Emacs?
I guess this and this could be an answer to your question.
Installation is easy. Invoke git clone [email protected]:antonj/Highlight-Indentation-for-Emacs.git .
in, say, ~/.emacs.d/highlight-indents
and add
(add-to-list 'load-path "~/.emacs.d/packages/highlight-indents/")
(require 'highlight-indentation)
to your .emacs
. Then, when visiting a file you can M-x highlight-indentation-mode RET
to enable the minor mode.
You can also use highlight-indent-guides-mode
and add it as a hook to prog-mode
, so that it gets loaded automatically.
In Spacemacs, I did it by first installing it with M-x package-install
or adding it as a user-defined package in .spacemacs
, then M-x customize-group
, prog-mode
, prog-mode
hooks, "ins", enter highlight-indent-guides-mode
.
You can configure it via M-x customize-group
highlight-indent-guides
and change the indent character, coloring, etc.
So far, it works wonders and renders quickly.
