writing your own theme and tabbar

writing your own theme and tabbar

I'm trying to develop/write my own theme which is doing more or less
what I want, except for 'tabbar'. This is what I have -
--8<---------------cut here---------------start------------->8---
 '(tabbar-selected-highlight ((t (:background "black" :foreground "red" :height 85))))
 '(tabbar-selected-modified ((t (:background "black" :foreground "red" :weight bold :height 85))))
 '(tabbar-default ((t (:inherit variable-pitch :background "gray" :foreground "black" :weight bold :height 85)))) 
 '(tabbar-selected ((t (:inherit tabbar-default :background "black" :foreground "red" :weight bold :height 85))))
 '(tabbar-modified ((t (:background "black" :foreground "red" :weight bold :height 85)))))
--8<---------------cut here---------------end--------------->8---

And what I'm looking for in the tab of the buffer that I'm in is a black
background with red text. But its not happening, instead what I'm
getting is red text on a light green background.

But, in buffers like *org-agenda-mode* or *org-agenda* it is showing
_exactly_ what I'm looking for. Red text on a black background.

Tabbar default is black text on a light-green background, and this seems
to be the code-source for it as its the only place where 'green' is
mentioned, from "tabbar.el" - 
--8<---------------cut here---------------start------------->8---
(defface tabbar-modified
  '((t
     :inherit tabbar-default
     :box (:line-width 1 :color "white" :style released-button)
     :foreground "green"
     ))
  "Face used for unsaved tabs."
  :group 'tabbar)
--8<---------------cut here---------------end--------------->8---

and tabbar-default is -
--8<---------------cut here---------------start------------->8---
(defface tabbar-default
  '(
    ;;(((class color grayscale) (background light))
    ;; :inherit variable-pitch
    ;; :height 0.8
    ;; :foreground "gray50"
    ;; :background "grey75"
    ;; )
    (((class color grayscale) (background dark))
     :inherit variable-pitch
     :height 0.8
     :foreground "grey75"
     :background "gray50"
     )
    (((class mono) (background light))
     :inherit variable-pitch
     :height 0.8
     :foreground "black"
     :background "white"
     )
    (((class mono) (background dark))
     :inherit variable-pitch
     :height 0.8
     :foreground "white"
     :background "black"
     )
    (t
     :inherit variable-pitch
     :height 0.8
     :foreground "gray50"
     :background "gray75"
     ))
  "Default face used in the tab bar."
  :group 'tabbar)
--8<---------------cut here---------------end--------------->8---

How can I achieve my goal please of red foreground on a black background
for every tab/buffer that is currently in use, i.e. I'm writing in that
buffer.

Thanks
Sharon.

Hello,

Do you use tabbar from <https://github.com/dholm/tabbar>?  I see there:

  tabbar-default
  tabbar-unselected
  tabbar-selected
  tabbar-modified
  tabbar-highlight
  tabbar-separator
  tabbar-button
  tabbar-button-highlight

but not `tabbar-selected-highlight' and `tabbar-selected-modified'.

But you seem to ask only about `tabbar-selected'.  I don't see problems
with that part.  I tried analagous code in my themes and it works.  The
only thought I have about that is: perhaps you have another line with
"tabbar-selected" somewhere in your theme which overrides that one.
If not, try your theme with "emacs -Q".

Thanks for this Alex.

I'm using "tabbar-20140316.600" from the elpa stable. I currently have
*every* tab with a black background and red foreground/text, and the
buffer that I'm working in is showing a green background and red
foreground! But I'm happy with that as the difference is easy to see. But
thanks anyway.

Sharon.

Before you do that, be sure you got the right face.

1. What is the name of the face you would like to
   change?

2. Change that face, either with custom-set-faces or
   `set-face-attribute'.

Did that work?

Here, you can find a method to do step one, and an example
how custom-set-faces can be used:

http://user.it.uu.se/~embe8573/conf/emacs-init/faces.el

Have you confirmed you are setting the correct face?

If so, can you confirm that you can set the face at
all? Set it to some arbitrary color - did it change?

If you have confirmed you are setting the correct face,
and that it responds to a change, you can use
describe-face in those modes that you mention to check
out the faces that you like (first, find out what those
faces are). Now set the face that you don't like to the
same values.

That's too reverse a way of doing it. I prefer the
method I describe (surprise). But If you do it your way,
sure, change tabbar-modified and see if it changes what
you want to change. But even if it does, it doesn't
mean that's the face - the sought-after face can be
inheriting from tabbar-modified and not setting that
property itself.

Find out what that face is, see if you can change it,
find out what you want to change it to, change it.

Good luck!
