why cant emacs 24 find a custom theme I added?

Question

My entire emacs setup is here

I loaded my init-theme.el file here

And supposedly that should make the darkclean theme available.

But when I type M-x load-theme TAB the darkclean theme is not listed.

How can I register it for Emacs 24?

Solution 1

If you install themes via elpa / package.el you'll notice that you need to add each theme folder into your custom-theme-load-path - this is a bit of a pain to do manually, especially when you take into account upgrades will create a new folder, e.g. 0.1.0 -> 0.1.2 will be a new folder inside your elpa folder.

Assuming you've installed your elpa packages into ~/.emacs.d/elpa/ add this script to your ~/.emacs.d/init.el

(require 'dash)
(require 's)

(-each
   (-map
      (lambda (item)
      (format "~/.emacs.d/elpa/%s" item))
   (-filter
      (lambda (item) (s-contains? "theme" item))
      (directory-files "~/.emacs.d/elpa/")))
   (lambda (item)
      (add-to-list 'custom-theme-load-path item)))

You'll need dash.el and s.el (available from elpa.)

init-themes has commented out the load path.

I have this (add-to-list 'custom-theme-load-path "~/.emacs.d/themes") and i think it found all my themes with M-x load-theme, enter then hit tab to see all the themes.

there was no search in the github for your repo, so i couldn't grep to see if you are doing it elsewhere. Also is your darkclean compatible with a 24 theme?

Edit: 1

actually i thought of another debug technique to rule out it being darkclean vs setup. put into your directory the solarized theme and if you don't see it in your load-theme you know it's you and not a theme, as solarized worked for me this way on emacs 24.

I don't enjoy it, and prefer wombat actually.

I m new to emacs and wanted to add some custom themes and create my own as well.

first add this

(add-to-list 'custom-theme-load-path "~/.emacs.d/themes")

then add any new theme to that folder. This first did not work and when i used load-theme the themes in ~/.emacs.d/thems where not loaded.

the documentation says:

Each theme file is named THEME-theme.el, where THEME is the theme name.

so renaming darklean.el to darkclean-theme.el did the trick

here is darkclean.el - github.com/metaperl/emacs/blob/master/themes/darkclean.el

FYI using el-get doesn't require manually updating your load-paths. I've verified mine got updated automatically with C-h v RET custom-theme-load-path.

@TimS. many themes will add themselves to the custom-theme-load-path automatically when installed (most newer/well maintained ones will at least.). The script above just adds those that don't. There's nothing in the el-get source itself which appears to do anything with the custom-theme-load-path, go ahead and grep it.

[Tim S.]

yeah, what I meant to say was that many themes installed will auto-update the path, not el-get itself... my mistake. Thanks.

Thanks for this :D

Ahh did the trick! Thanks, was pulling my hair out why my theme couldn't be found until I saw you just had to add -theme to the end. Thanks a million!
