How to change Hash color in rhtml-mode in Emacs -


i'm using rhtml-mode in emacs.

when write hash in way :key => "value" :key colorized.

but key: "value" style colorizing doesn't work. color of : changed.

i tried change rhtml-mode bit. mode seems load ruby-mode internally if text if braced in <% %> tag. oddly when write hash in ruby-mode both type of writing colorized.

i'm using default ruby-mode in emacs24.

how can find place (by line number) color of hash key defined?

the short answer: c-h vrhtml-in-erb-keywords. open buffer showing regexp rhtml keywords. there link straight defined in elisp file. can see definition here.

add following .emacs file:

(add-hook 'rhtml-mode           (lambda ()            (font-lock-add-keywords nil             '(("\\([0-9a-za-z_]*:\\)" 1               font-lock-constant-face t)))))

this make emacs apply colouring determined font-lock-constant-face matches regexp "\\([0-9a-za-z_]*:\\)". might match more want, may want fine tune it.

i'm not sure there's particularly easy way find out colour given keyword found. can m-xdescribe-face point on word want information on. tell how emacs thinks should coloured - font-lock-keyword-face. c-h vfont-lock-keyword tell how emacs decided that, not in helpful way.

the simplest way open source code mode you're in , search in defines keywords. can open source code c-h frhtml-mode, open buffer link source.

Java, Hibernate, MySQL - store UTC date-time -
