This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org. Please check that
the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgement at that address.
Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
I found a confusing behaviour for customization. To trigger the
behavior, assign a value of "t" to org-habit-show-all-today. What I
found is:
- If you start emacs and immediately go into *shell* and print org-habit-show-today-all you get an error because that variable has not yet been bound.
: Debugger entered--Lisp error: (void-variable org-habit-show-all-today)
: (print org-habit-show-all-today)
: eval((print org-habit-show-all-today) nil)
: eval-last-sexp-1(t)
: eval-last-sexp(t)
: eval-print-last-sexp()
: call-interactively(eval-print-last-sexp nil nil)
- If you start emacs and immediately go into options->config for org-habit, the org-habit-show-today-all will indicate that it has been set outside of the customization system when the customized value is "t". When the customized value is "nil" there is no indicated problem.
- If you start emacs and put a buffer into org mode, the (print
org-habit-show-all) will show the customized value, and the
options->config will also show the customized value.
This behavior is not documented, which would be one fix. But a naive
user would expect that starting the customization process for the group
would also cause processing of the startup customization.

Customization only applies settings when relevant. Otherwise it would
have to unconditionally load at startup every package in which you have
customized an option. Use plain-old setq if you need different behaviour.

Sounds like a bug. However, there is no "org-habit-show-today-all"
variable in the Emacs trunk so I cannot test this. I cannot reproduce
this when customizing eg
org-export-html-table-use-header-tags-for-first-column.

I don't really know what this means.

Sorry, it's org-habit-show-all-today.

As you say, customization only applies when relevant. I would expect
that customizing would make it relevant, just like setting a buffer into
org-mode makes it relevant. But the bug might be something else
entirely.

I don't have that variable either.
I imagine any issue is related to the one you already reported
http://lists.gnu.org/archive/html/emacs-orgmode/2012-09/msg00666.html
-(defvar org-habit-show-all-today nil)
+(defvar org-habit-show-all-today)
The original version is an obvious bug.

BTW, here is the relevant quote from the elisp manual (it's not really
relevant for the Emacs manual IMO):
-- Function: custom-set-variables &rest args
This function installs the variable customizations specified by
ARGS. Each argument in ARGS should have the form
(VAR EXPRESSION [NOW [REQUEST [COMMENT]]])
VAR is a variable name (a symbol), and EXPRESSION is an expression
which evaluates to the desired customized value.
If the `defcustom' form for VAR has been evaluated prior to this
`custom-set-variables' call, EXPRESSION is immediately evaluated,
and the variable's value is set to the result. Otherwise,
EXPRESSION is stored into the variable's `saved-value' property,
to be evaluated when the relevant `defcustom' is called (usually
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
when the library defining that variable is loaded into Emacs).
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
