In emacs there is a mode show-paren-mode which colors the opposite matching parenthesis when the cursor is on the other. I wrote an example explaining show-paren-mode:
( <-colored colored-> )| <-cursor
However it does not work when the cursor is not on the parenthesis:
( <-not colored cursor inside->| not colored-> )
How can I enable this? I find that when performing slurpage and barfage in paredit I cannot keep track of the parentheses very well because they are not colored unless I am on them.
This is optimal:
( <-colored cursor inside->| colored-> )
Edit: Thanks to the comment by @lawlist I have resolved this issue.
Thanks to a comment by lawlist I have added the code from his answer on another question into my init file.
It colors each set of matching parentheses in a rainbow pattern.
