different colors for different highlights

[c02y]

The default highlight color of Prefix is green, the color of string defined in guide-key/highlight-command-regexp and guide-key/add-local-highlight-command-regexp are all yellow, can I specific a color for a specific string??

For example, I got

(setq guide-key/highlight-command-regexp "rectangle\\|register\\|helm\\|projectile")

and:

(add-hook 'c-mode-common-hook
      (lambda ()
        (guide-key/add-local-highlight-command-regexp "cscope")
        (guide-key/add-local-highlight-command-regexp "ggtags")
        ))

How can I make helm-related and projectile-related functions be highlighted in different colors?

BTW, what is the meaning of \\ in "rectangle\\|register\\|helm\\|projectile"?

You can specify a face of a regexp in guide-key/highlight-command-regexp as below.

(setq guide-key/highlight-command-regexp
      '(("^helm-" . warning)
        ("^projectile-" . error)))

Choose your favorite face instead of warning or error.

If mode specific setting, use guide-key/add-local-highlight-command-regexp.

(add-hook 'c-mode-common-hook
      (lambda ()
        (guide-key/add-local-highlight-command-regexp '("^helm-" . warning))
        (guide-key/add-local-highlight-command-regexp '("^projectile-" . error))
        ))

I'm sorry but this feature is not documented in README.org.
I'll add the documentation ASAP.

The meaning of \\| in "rectangle\\|register\\|helm\\|projectile" is the OR operator of regular expression.

The OR operator of Emacs Lisp regular expression is \| and \ need to escape in Emacs Lisp string. See http://www.gnu.org/software/emacs/manual/html_node/elisp/Regexp-Backslash.html#Regexp-Backslash in detail.

Besides warning and error faces you mentioned, there are several more faces at Basic_faces page, although they are enough, is is possible to set the colors like white, red, yellow??

I've implemented this feature. Try it from MELPA or github.

Please specify your favorite color name as string.

(setq guide-key/highlight-command-regexp
      '(("^helm-" . "sky blue")
        ("^projectile-" . "hot pink")))

You can get available color names by list-colors-display.
