how to specify notmuch colors in emacs24

how to specify notmuch colors in emacs24

[David Belohrad]

Dear All,

so far I'm changing some color faces programmatically:

  (setq notmuch-search-line-faces '(("deleted" . (:foreground "red"
                                                  :background "blue"))
                                     ("unread" . (:foreground "DeepSkyBlue"))
                                     ("flagged" . (:foreground "firebrick1"))
                                     ))


I recently upgraded to emacs24. I was using default shipped tango-dark
theme. Then (because of VHDL mode I'm using) I have created a custom
theme, and I'd like to 'backport' the piece of code above into the
custom theme so it is in accordance with the philosophy of themes.

I have no idea how to specify it using the 'class approach',as e.g.

   `(gnus-group-news-1 ((,class (:foreground ,plum-1))))
   `(gnus-group-news-1-low ((,class (:foreground ,plum-2))))

Any hint would be greatly appreciated

d.

I use custom-set-faces and themes for this kind of customisation.

You could get some ideas from my theme.

<https://github.com/suvayu/.emacs.d/blob/master/themes/dark-emacs-theme.el>

Essentially it boils down to:

  ((type <type>) (class <color/monochrome/etc>) (min-colors <number>))

You can find the gory docs here: (info "(elisp) Defining Faces")

Hope this helps,

I'm not sure what the values of `class', `plum-1', and `plum-2' are in
your above snippet or what the context of that snippet is, so I may be
misunderstanding your problem, but it may help to know that
`gnus-group-news-1' and `notmuch-search-line-faces' are very different
types of variables.

The value of `gnus-group-news-1' is a face; something like
(:foreground "plum1").  It looks like what you've written above is
actually a "face specification", which uses a bunch of conditions (the
,class part) to determine which of several potential faces to assign
to the variable (though you listed only one face for each variable, so
I'm not sure why you have a condition).  It's unfortunate that Emacs
distinguishes faces and face specification, but that's how it is.

`notmuch-search-line-faces' is *not* a face variable like
`gnus-group-news-1'.  It's an association list that maps tags to
faces.  As such, it won't work if your theme is trying to treat it
like a face variable, since its value is not a face, but rather a data
structure that has faces in it.

Hi All,

thanks for extensive answers on this thread. The plum-1 and other
definitions are coming from 'tango-dark' theme of emacs 24, which I
wanted to modify. I understood hence, that the two ways of settings the
colors (notmuch/emacs24) are so far somehow incompatible and hence there
is no way how to specify the notmuch colors the emacs24 way.

many thanks
