bug#21667: 24.5; color-theme-buffer-local package misses a dependency

[Ryo Furue]

Dear emacs maintainers,

The "color-theme-buffer-local" package seems to require the "color-theme"
package but it doesn't "require" it (that is, doesn't list it as a
dependency).  I guess this is the reason why I got =E2=80=9CCannot open load
file, color-theme" when installing color-theme-buffer-local.  This error
went away when I first installed the color-theme package before
installing the color-theme-buffer-local package.

Dunno what "color-theme-buffer-local" package is.  I suspect that
it is not part of GNU Emacs but is a 3rd-party package.

In any case, library `color-theme.el' is not part of Emacs.  It is
3rd-party.

It is unfortunate that when Emacs added "custom" themes it
introduced a lot of confusion wrt custom themes vs color themes.
This was compounded by some (rash) statements that the former
somehow replaces the latter.  The two are different, with only
some overlapping features.

I'm guessing that you should report this problem to the maintainer
of "color-theme-buffer-local" package, not to GNU Emacs development.

This page might help with the confusion between custom themes
and color themes:

Dear Drew Adams,

Thank you for your detailed explanation and sorry for submitting the
report to this list.

I've forwarded the report to the author of that elisp code.  (But, I
don't know if s/he is the "packager" of it.)

For my education, may I ask which part of the emacs package system
(package.el ?) belongs to emacs proper?  The whole thing?  It's always
hard to know which part of a big system (another example is LaTeX) is
maintained by whom.

[. . .]

So, are both"theming systems" themselves part of emacs proper, even if
each theme is 3rd party?

Regards,

Ryo

Someone else can answer that better than I.  But I think that
all of the code involved specifically with accessing, downloading,
and installing Emacs libraries belongs to Emacs.  But perhaps it
also depends on what you really mean - by "belong" and by "Emacs
proper", for instance.  Certainly `package.el' is the heart of
what is involved, if it is not all of it, and that is part of
GNU Emacs as distributed.

Dunno what "Emacs proper" means; sorry.  `color-theme.el' is
not included as part of GNU Emacs.  It is a 3rd-party library.
