help with modifying a bit of code in .emacs

help with modifying a bit of code in .emacs

[Graham Smith]

[-- Attachment #1.1: Type: text/plain, Size: 1433 bytes --]

I have been using the set up provided by John Wiegley on a Mac and have
tried to to use it with Emacs32 wbut with some problems as the
custom-set-variables command seemed to badly interact with the Emacs32w
custom-set-variables.

I have been trying to rewrite the code to avoid the custom-set-variables in
.emacs but have finally come unstuck with this bit:

;(setq org-agenda-custom-commands
;             '(("d" todo #("DELEGATED" nil)
;          ("c" todo #("DONE|DEFERRED|CANCELLED" nil)
;          ("w" todo #("WAITING" nil)
;              ("W" agenda "" ((org-agenda-ndays 21)))
;     ("A" agenda ""
;        ((org-agenda-skip-function
;         (lambda nil
;               (org-agenda-skip-entry-if (quote notregexp)
"\\=.*\\[#A\\]")))
;               (org-agenda-ndays 1)
;               (org-agenda-overriding-header "Today's Priority #A tasks:
")))
;("u" alltodo ""
;((org-agenda-skip-function
;  (lambda nil
;    (org-agenda-skip-entry-if (quote scheduled) (quote deadline)
;                  (quote regexp) "<[^>\n]+>")))
;(org-agenda-overriding-header "Unscheduled TODO entries: "))))))

I am getting An error has occurred while loading `c:/Home/.emacs':

"Invalid read syntax: Invalid string property list" error when launching
Emacs and narrowed it down to this bit of code. Can anyone point out where
this is wrong. The rest of it loads OK, its just this bit which is failing.

Can anyone help.

Many thanks,

Graham

I have no specific help to offer, but you should be able to narrow
down the problem further by turning on debugging of your init file.
Starting from a unix command line, this would be "emacs --debug-init
&", but I have no idea whether this would work on windows. If you
can't work out how to do this on windows, you could use a more
roundabout method as follows:

1. temporarily remove/comment the problematic code from your .emacs
and put it in a separate file, say "bad-code.el"
2. restart emacs
3. turn on debugging with
   M-x set-variable RET debug-on-error RET t RET
4. evaluate the problematic code by doing
   M-x load-file RET path/to/bad-code.el RET

In principle, either of these methods should give you a lisp backtrace
indicating exactly what the offending command is. Even if you don't
understand the backtrace, it might help someone else to diagnose your
problem.

Cheers

Will

William,

Thanks, this has now been fixed, and the code that works is:

(setq org-agenda-custom-commands
      '(
        ("d" todo #("DELEGATED") nil)
        ("c" todo #("DONE|DEFERRED|CANCELLED") nil)
        ("w" todo #("WAITING") nil)
        ("W" agenda "" ((org-agenda-ndays 21)))
        ("A" agenda "" ((org-agenda-skip-function
                           (lambda nil (org-agenda-skip-entry-if (quote
notregexp) "\\=.*\\[#A\\]")))
                        (org-agenda-ndays 1)
                        (org-agenda-overriding-header "Today's Priority #A
tasks: ")))
        ("u" alltodo "" ((org-agenda-skip-function
                          (lambda nil (org-agenda-skip-entry-if (quote
scheduled) (quote deadline)
                                                                (quote
regexp) "<[^>\n]+>")))
                         (org-agenda-overriding-header "Unscheduled TODO
entries: ")))))


I got some help sent directly to me, didn't realise it wasn't on the list
and then go t side tracked into other bits that didn't work.

But the backtrace info is useful to have.

Thanks,

Graham

The #(...) is attempting to set a text property on the string
"DELEGATED".  Apparently nil is not valid in this location.  See
section 2.3.8.4 in the Elisp info document.  Since nil probably means
no property, you can just eliminate the #() syntax.

Also, your parentheses don't match up; you need extra closing parens
after some entries to make a well-formed list.  You probably want to
end up with something like this (not tested but at least it evaluates
without error):

(setq org-agenda-custom-commands
      '(("d" todo ("DELEGATED"))
        ("c" todo ("DONE|DEFERRED|CANCELLED"))
        ("w" todo ("WAITING"))
        ("W" agenda "" ((org-agenda-ndays 21)))
        ("A" agenda "" ((org-agenda-skip-function
                         (lambda nil
                           (org-agenda-skip-entry-if (quote notregexp)
"\\=.*\\[#A\\]")))
                        (org-agenda-ndays 1)
                        (org-agenda-overriding-header "Today's
Priority #A tasks: ")))
        ("u" alltodo "" ((org-agenda-skip-function
                          (lambda nil
                            (org-agenda-skip-entry-if (quote
scheduled) (quote deadline)
                                                      (quote regexp)
"<[^>\n]+>")))
                         (org-agenda-overriding-header "Unscheduled
TODO entries: ")))))

Chris,

Thanks, this looks pretty well what I ended up with after some help off-list
(I've only realised it was off list, and thought I had already replied to
the list.

The code I ended up with is:

(setq org-agenda-custom-commands
      '(
        ("d" todo #("DELEGATED") nil)
        ("c" todo #("DONE|DEFERRED|CANCELLED") nil)
        ("w" todo #("WAITING") nil)
        ("W" agenda "" ((org-agenda-ndays 21)))
        ("A" agenda "" ((org-agenda-skip-function
                           (lambda nil (org-agenda-skip-entry-if (quote
notregexp) "\\=.*\\[#A\\]")))
                        (org-agenda-ndays 1)
                        (org-agenda-overriding-header "Today's Priority #A
tasks: ")))
        ("u" alltodo "" ((org-agenda-skip-function
                          (lambda nil (org-agenda-skip-entry-if (quote
scheduled) (quote deadline)
                                                                (quote
regexp) "<[^>\n]+>")))
                         (org-agenda-overriding-header "Unscheduled TODO
entries: ")))))

Which I think is the same as you suggest. And thanks for the explanations,
these were useful.

Graham
