Having Issues With Using 'hallo.el' Example Theme, And Creating A Custom Theme

Having Issues With Using 'hallo.el' Example Theme, And Creating A Custom Theme

[Samuel Banya]

Hey there,
I've been following along with this video:
Emacs Tips - How to Create Your Own Color Theme (https://www.youtube.com/watch?v=kCCIudu53Zg)

This video basically uses this theme as an example with the 'autothemer' MELPA package:
https://github.com/daviwil/emacs-from-scratch/blob/master/hallo-theme.el

The problem I have is, I can't get even the example 'hallo' theme to load with 'M-x load-theme hallo'.

More so, I've been trying to create my own Morrowind theme here:
https://github.com/SamuelBanya/emacs-morrowind-theme

Both themes just won't work.

I have a literate config, so here's config on GitHub with 'configuration.org' and 'init.el' present:
https://github.com/SamuelBanya/SamsEmacs 

Here's the current output of ~/.emacs.d on my machine (NOTE: The symlinks are because I use GNU Stow to stow away dotfiles like this with 'stow -t ~/.emacs.d'):
  /home/sam/.emacs.d:
  total used in directory 24 available 286.2 GiB

  lrwxrwxrwx  1 sam sam   38 May 15 13:36 word-perfect-theme.el -> ../hub/SamsEmacs/word-perfect-theme.el

Here's the debugger output when I attempted to load the theme:
Debugger entered--Lisp error: (error "Unable to find theme file for ‘emacs-morrowind’")
  signal(error ("Unable to find theme file for ‘emacs-morrowind’"))
  error("Unable to find theme file for `%s'" emacs-morrowind)

  eval((load-theme 'emacs-morrowind t) t)

  funcall-interactively(eval-expression (load-theme 'emacs-morrowind t) nil nil 127)
  call-interactively(eval-expression nil nil)
  command-execute(eval-expression)

Thanks!

Sam

Minor change in links, I changed the location of my custom theme to here:
https://github.com/SamuelBanya/morrowind-emacs-theme

What version of Emacs is that?

And what is the value of the variable custom-theme-load-path?

Re: Having Issues With Using 'hallo.el' Example Theme, And Creating A Custom Theme

[Samuel Banya]

Output that you requested:

custom-theme-load-path is a variable defined in ‘custom.el’.

Its value is
("/home/sam/.emacs.d/elpa/gruvbox-theme-20220101.1208/" "/home/sam/.emacs.d/elpa/spacemacs-theme-20220430.2248/" custom-theme-directory t)

List of directories to search for custom theme files.
When loading custom themes (e.g. in ‘customize-themes’ and
‘load-theme’), Emacs searches for theme files in the specified
order.  Each element in the list should be one of the following:
- the symbol ‘custom-theme-directory’, meaning the value of
  ‘custom-theme-directory’.
- the symbol t, meaning the built-in theme directory (a directory
  named "themes" in ‘data-directory’).
- a directory name (a string).

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

This variable is designed for use in lisp code (including
external packages).  For manual user customizations, use
‘custom-theme-directory’ instead.

  Probably introduced at or before Emacs version 24.1.

You can get the Emacs version from/in Emacs with
`emacs-version', and with C-u it inserts as well,
i.e. C-u M-x emacs-version RET

  GNU Emacs 29.0.50 (build 1, x86_64-pc-linux-gnu, cairo
  version 1.16.0) of 2021-12-31

You have to fill it manually tho if the line gets to long.
They are working on it ...

If you say

  (load-theme 'emacs-morrowind t)

then Emacs will look for a file named "emacs-morrowind-theme.el".  But
your theme file's name is just "emacs-morrowind.el".
