I am following the Xah Lee's example bellow to create my own major mode for syntax coloring.
http://xahlee.org/emacs/elisp_syntax_coloring.html
My goal is to highlight all lines that begin with "E | ...."
so following the example I add the following to my .emacs file
'(("Sin\\|Cos\\|Sum" . font-lock-function-name-face)
("Pi\\|Infinity" . font-lock-constant-face)
)
;; I tested the following regular expression using search-forward-regex
(setq nlDataKeywords
'(("^E +| +*$" )) . font-lock-warning-face)
)
)
(define-derived-mode nl-data-mode fundamental-mode
(setq font-lock-defautls '(nlDataKeywords)
)
)
The .emacs file loads without errors, but when I set the mode to nl-data-mode I get the following error in the mini-buffer:
Only strings should be stored in the buffer-local variable mode-name.
I tried moving the changes to my ~/.emacs.el fiel and loading that with the same result. I tried using regexp-quote function, all with the same errors
(setq nlDataKeywords
'(
( ,(regexp-quote '("^E +| +*$" )) . font-lock-warning-face)
)
)
(define-derived-mode nl-data-mode fundamental-mode
(setq font-lock-defautls '(nlDataKeywords)
)
)
Can someone knowledgeable on the mail list help me out?
Thanks and best regards,
Carlos

Hi Carlos,
Thanks for checking out my tutorial.
There are few errors in your code.
• font-lock-defaults is spelled wrong.
• the paren nesting structure is wrong in your (setq
nlDataKeywords ...)
here's the code you might want:
(setq nlDataKeywords
'( ("^E +| *.+$" . font-lock-warning-face) )
)
(define-derived-mode nl-data-mode fundamental-mode
(setq font-lock-defaults '(nlDataKeywords)
)
)
If you turn on the mode, the following line will be highlighted.
E | something ...
