(setq myKeywordsLevel1
(list
("Sin\\|Cos" . font-lock-function-name-face)
("π\\|∞" . font-lock-constant-face)
("x\\|y" . font-lock-variable-name-face)))
Are you sure? It gives (invalid-function "Sin\\|Cos").

Thanks.
I tried the following but still not working:
; Sin[x]^2 + Cos[y]^2 = 1
; π^2/6 == Sum[1/x^2,{x,1,∞}]
(setq myKeywordsLevel1
'(
("Sin\\|Cos" . font-lock-function-name-face)
("π\\|∞" . font-lock-constant-face)
("x\\|y" . font-lock-variable-name-face)
)
)
(setq font-lock-keywords
'(
myKeywordsLevel1
)
)
(font-lock-fontify-buffer)
... quite frustrated by this.
after eval that form, than i looked at the value of font-lock-keywords
using describe-variable, it says:
«
Its value is
(t
(myKeywordsLevel1)
(myKeywordsLevel1
(0 font-lock-keyword-face)))
Local in buffer untitled<3>;
»
Where did all the extra came from?
I tried various quoting, like “'((...) ...)”, “(quote (list ...))”,
“`( ,...)” in one or the other code block, and also tried a deeper
nested for the value of the value for font-lock-keywords ... (... some
background: am trying to write lsl-mode (yes i know existing ones) and
meanwhile write a simple tutorial about writing mode from the ground
up. I have read the chapters on major mode and font lock mode, also
have taken apart few lang modes. I have a working mode but want
understanding and a simple example.)
Thanks.
