Thanks...
am having a headache with this.
;Why does the following works:
; Sin[x]^2 + Cos[y]^2 = 1
; π^2/6 == Sum[1/x^2,{x,1,∞}]
(setq font-lock-keywords
(quote
(
("Sin\\|Cos" . font-lock-function-name-face)
("π\\|∞" . font-lock-constant-face)
("x\\|y" . font-lock-variable-name-face)
)
nil
nil
)
)
;But in the following, i put my keywords into a var, the value of
myKeywordsLevel1 is just the first element ("Sin\\|Cos" . font-lock-
function-name-face)?
(setq myKeywordsLevel1
(quote
("Sin\\|Cos" . font-lock-function-name-face)
("π\\|∞" . font-lock-constant-face)
("x\\|y" . font-lock-variable-name-face)
)
)
(setq font-lock-keywords
`(
,myKeywordsLevel1
nil
nil
)
)
(font-lock-fontify-buffer)
