nicely managing multiple calendars in the agenda

nicely managing multiple calendars in the agenda

[Eraldo Helal]

I have switched to using org files as 'calendars'. (events.org, university.org, etc)
I am using the agenda to view them.

However I am still having some troubles with 2 things:
1. different colors for different calendars (e.g. entries from events.org in orange)
2. toggling the visibility of individual calendars

=> 1
    Would it be possible to use different faces for different files?
    Or maybe even different faces for different categories?
    ,---- What I have:
    |[blue ] Saturday    1 May 2010
    |[black]   events:      Adam's party
    |[black]   events:      Magic show
    |[black]   university:  10:15-12:00 Management test
    `----
    ,---- What I want:
    |[blue  ] Saturday    1 May 2010
    |[orange]   events:      Adam's party
    |[orange]   events:      Adam's party
    |[purple]   university:  10:15-12:00 Management test
    `----

=> 2
    I do know that I can restrict the agenda to a single file,
    but how can I toggle the visibility of a single file? (e.g. exclude one file)
    Plus... Once I have toggled one file invisible...
    I would need some kind of overview of which files(calendars) are hidden and which ones are still active.

    One possible workaround would be using file-tags and filtering by them.
    While I do like the idea, it still does not solve the issue of knowing
    which files(calendars) are active and which ones are hidden at the moment.
    Plus I would be even happier if we could find a solution without using tags.

    A menu (just like the todo-kwd menu <C-c t>) would be ideal as an interface for toggling calendars
    and getting an overview of the currently displayed ones.

What I do is having tags with different colors:

--8<---------------cut here---------------start------------->8---
    (setq org-tag-faces
          '(("home" . (:background "#D4EAFF" :italic t))
            ("work" . (:italic t :background "#F9E816"))))
--8<---------------cut here---------------end--------------->8---

Though, only the color spec above is taken into account. Tags are not in
italics like for all the others:

--8<---------------cut here---------------start------------->8---
     (org-tag ((t (:foreground "rgb:81/6A/7D" :background "rgb:F7/B8/DE" :italic t))))
--8<---------------cut here---------------end--------------->8---

Maybe a bug?

Best regards,
  Seb

Or maybe the font does not come in italic? AFAIK, if that's the case, then
the italic attribute is just ignored.

Nice try -- and you're definitely right asking (as this could easily be
overlooked), but here that's not the case: my font is Consolas (under Ubuntu),
which comes in italics.

And I get _all the tags in italics_, thanks to the above specification of
`org-tag' -- _all but 2_ tags: `home' and `work', which come in their upright
version, independently of the argument passed in `org-tag-faces'.

Thanks for helping...

I've just noticed, in the 1000's of lines in my `*Messages*' buffer, something
that can explain the noticed behavior:

--8<---------------cut here---------------start------------->8---
Invalid face attribute :italic t [54 times]
--8<---------------cut here---------------end--------------->8---

Though, I don't understand why that attribute is invalid in the above spec!?

Any idea?

Best regards,
  Seb

Seb,

fonts/faces/etc are a tangled set of twisty passages, all looking
different to me (or maybe they look all the same - I can't tell).

That said, I can only suggest what I tried in my case. I set
org-tag-faces as above, added a :home: tag to a TODO item, placed the
cursor on a character in the tag and then did `C-u M-x
what-cursor-position'. I got the following:

,----
|         character: m (109, #o155, #x6d)
| preferred charset: ascii (ASCII (ISO646 IRV))
|        code point: 0x6D
|            syntax: w 	which means: word
|          category: .:Base, a:ASCII, l:Latin, r:Roman
|       buffer code: #x6D
|         file code: #x6D
|           display: by this font (glyph code)
|     x:-misc-fixed-medium-r-normal--15-140-75-75-c-90-iso8859-1 (#x6D)
| 
| Character code properties: customize what to show
|   name: LATIN SMALL LETTER M
|   general-category: Ll (Letter, Lowercase)
| 
| There are text properties here:
|   face                 (:background "#D4EAFF" :italic t)
|   font-lock-fontified  t
|   fontified            t
|   keymap               [Show]
|   mouse-face           highlight
|   org-no-flyspell      t
`----

so the face attributes obey what org-tag-faces said, but I
think the font itself cannot do what is asked:

  (font-face-attributes "-misc-fixed-medium-r-normal--15-140-75-75-c-90-iso8859-1")

gives

  (:family "fixed" :height 145 :weight normal :slant normal :width normal)

This applies to my setup of course, so YMMV, but it seemed likely that
that's what you were running into, hence my question.

You might be able to use the mechanisms described in sec. 38.12.8, "Font
Selection", of the Emacs Lisp manual to accomplish what you want, but
I can't help you there: I decided a long time ago not to step foot into
those waters.

HTH (but I doubt it),

Replacing `:italic t' by `:slant italic' does the trick!

--8<---------------cut here---------------start------------->8---
    (setq org-tag-faces
          '(("home" . (:slant italic :background "pale green"))
            ("work" . (:slant italic :background "#F9E816"))))
--8<---------------cut here---------------end--------------->8---

Just wanted to share the solution...

  Seb
