faces for rainbow-delimiter-mode not applied

[duud]

Faces for rainbow-delimiter-mode are inherited from outline mode. After starting emacs and opening an elisp file none of the outline-faces are defined (checked with describe-face), since rainbow-delimiter-mode faces inherit from outline-mode faces, coloring of delimiters isn't working. I order to get this working I have to enable outline-mode (after doing this faces for outline-mode get defined) and restartd rainbow-delomiter-mode.

I think I have the same issue: https://github.com/Fanael/rainbow-delimiters/issues/21#issuecomment-194058177 (demo here: https://asciinema.org/a/allvq9du5q9fpnr46d2xn3kiq). Enabling outline-mode then emacs-lisp-mode (or whatever major mode I was in) seems to fix the issue.

rainbow-delimitiers appears to work with this config:

(use-package rainbow-delimiters                                                               
  :config (add-hook 'prog-mode-hook 'rainbow-delimiters-mode)) 

;;; ...

(use-package color-theme-solarized                                                            
  :init (require 'color-theme)                                                                
  :config                                                                                     
  (add-to-list 'custom-theme-load-path "emacs-color-theme-solarized")                         
  (load-theme 'solarized t))

Scratch that, that config's not working now. Oddly enough it works when first installing the packages, but after restarting emacs it doesn't.

Not sure if this'll help... but I'm seeing the following paragraph twice in *Messages*:

Even after following the instructions in https://github.com/sellout/emacs-color-theme-solarized/issues/175, which meant the following config:

(use-package color-theme-solarized                                                                       
  :init                                                                                                  
  (setq-default solarized-termcolors 256)                                                                
  (require 'color-theme)                                                                                 
  (load-theme 'solarized t))      

The warnings go away if I don't load this package, so I'm assuming it's caused by this package.

Any progress on this?

If you prefer the way it looks with 16 colors, then setting TERM to xterm-color should make the warnings go away. If you enjoy the way it looks with 256 colors, then setting TERM to xterm-256color should make the warnings go away.

I use 16 colors and this workaround, which works for me.

I thought I was going nuts, so glad to find this issue. I am in the middle of refactoring my .emacs and was a bit upset when rainbow delimiters stopped working in solarized for some unknown reason because it looks fantastic with them. Thanks to @duud and @losingkeys I was able to get them working again using the outline-minor-mode hack.

Here is a minimal repro for the issue. It assumes you have the solarized theme and rainbow delimiters installed, and optionally for comparison purposes the gruvbox theme.

Save the following code in a file called emacs.srd.el:

(package-initialize)

(setq frame-background-mode 'dark)
(mapc 'frame-set-background-mode (frame-list))
(load-theme 'solarized t)
;(load-theme 'gruvbox t)

(require 'rainbow-delimiters)
(add-hook 'prog-mode-hook #'rainbow-delimiters-mode)

;; If you comment these two lines out, rainbow delimiters no longer work with
;; solarized, though they do still work with gruvbox.
(outline-minor-mode t)
(outline-minor-mode nil)

Then if you start Emacs with

emacs -q -l emacs.srd.el emacs.srd.el

You don't get rainbow delimiters unless you have the outline-minor-mode toggle.
