Hi.
I found a problem on speedbar and imenu.
Reproducing date is here
-8<---------------cut here---------------start------------->8---
* someday/maybe
* SOMEDAY/maybe
* SOMEDAY maybe
* someday maybe
* read/review
* READ/review
* conf
#+TYP_TODO: SOMEDAY
--8<---------------cut here---------------end--------------->8---

When a head line includes TODO state name,
I am afraid that displayed head line names on speedbar are wrong.
Because SOMEDAY is TODO type but "someday/maybe" and "SOMEDAY/maybe"
is not TODO task.

Regards.

I am not able to reproduce this on 

GNU Emacs 23.1.1 (i686-pc-linux-gnu, GTK+ Version 2.12.12)
 of 2010-01-30 on noorul

Org-mode version 7.01trans (release_6.36.723.gaf9d)

I won't answer your mail. Sorry. Just having a question: how do you have the
red "V" after the file names?  Is it some sort of versioning marker?

Best regards,

I don't set by my effort, but I manage org files with git(vc-git).


I can reproduce this on
GNU Emacs 23.2.1 (i386-mingw-nt6.0.6002) of 2010-05-08 on PC
Org-mode version 7.01trans (release_7.01g.22.gec034.dirty)

I can confirm this with Org-mode version 7.01trans
(release_7.01g.26.g24bb.dirty) on GNU Emacs 23.2.1 (i486-pc-linux-gnu,
GTK+ Version 2.20.0) of 2010-05-16 on raven, modified by Debian.

This is a regexp problem: `org-complex-heading-regexp' recognizes
"someday" and a TODO keyword in both "someday/maybe" and
"SOMEDAY/maybe".

It is defined as the following (I let the concat form for better
readability):

#+begin_src emacs-lisp
(concat "^\\(\\*+\\)[ \t]+\\(?:\\("
	(mapconcat 'regexp-quote org-todo-keywords-1 "\\|")
	"\\)\\>\\)?\\(?:[ \t]*\\(\\[#.\\]\\)\\)?[ \t]*\\(.*?\\)"
	"\\(?:[ \t]+\\(:[[:alnum:]_@#%:]+:\\)\\)?[ \t]*$")
#+end_src

The problem in at the "\\>" part. The following change may solve the
problem.

#+begin_src emacs-lisp
(concat "^\\(\\*+\\)[ \t]+\\(?:\\("
	(mapconcat 'regexp-quote org-todo-keywords-1 "\\|")
	"\\)[ \t]+\\)?\\(?:[ \t]*\\(\\[#.\\]\\)\\)?[ \t]*\\(.*?\\)"
	"\\(?:[ \t]+\\(:[[:alnum:]_@#%:]+:\\)\\)?[ \t]*$")
#+end_src

I think it is better to enforce some whitespace after a TODO keyword
than a word boundary. There are a few places where this could also be
changed (i.e. `org-complex-heading-regexp-format').

Any opinion on this?

Regards,

Yep.  When you have some free time (!), please suggest a patch and a
small org test file so that we can test.

Here is an attempt to convert word boundaries into white spaces where it
matters.

I paste again the test file from Osamu Okano for reference.

Thanks a lot -- I have tested the patch during the last two hours and
didn't find any problem.  Feel free to apply it.

What about going one step further and removing the possibility of 
using tabs after TODO keywords?

Best,

Done.

There are quite a few places indeed using "[ \t]" which may use " "
instead. Before TODO keywords, before priority cookies, before
check-boxes, etc.

We might remove any use of [ \t] but for indentation. Though, I don't
use tabs, and there could well be corner cases that I can't see[1].

I am not sure this is a good idea.  With this patch, you always
require the space to be there.  So "* TODO" would not be a task.
I am not sure, this might have side effects.

Notwithstanding the fontification problem, isn't "* TODO" considered as
a valid task, whose text is "TODO" and without a keyword?

Well, the behavior is really undefined on these border cases.
My worries also stem from the possibility that the match
of these regexps now extends an additional character, and
there may be places in the code which rely on (match-end 0)
being right after (e.g.) the TODO keyword.
I do not know if this is the case, but it
is a definite possibility.

FWIW, I'm not in favor of this -- I'd rather consider it a task with a
todo keyword but with no "true headline".

Enforcing " " _before_ the places you mention would be good change.
Feel free to commit such a change if you have some time.

There are side-effects to the current behavior.

Basically, in headlines like "* TODO", the TODO keyword will not be
matched correctly.  So in column view, "TODO" will be displayed as the
ITEM instead of the TODO keyword, which will certainly be confusing for
users (see my other email).

I suggest enforcing [ \t\n] instead of [ \t] to make sure those
headlines are handled correctly.

Whether this is the case or not, I think the correct fix is to 
enforce [ \t\n] _outside_ the TODO keyword submatch.

Nicolas, can you make the two suggested changes, i.e. using 
[ \t\n] and make sure this string is required outside the TODO 
keyword submatch? 

If you don't have time just let me know and I'll do it.

Thanks!

FWIW bis, I would make the exact same interpretation as you do, Bastien.

I don't mind providing a commit for this, but the list wasn't
exhaustive. I'd rather have a set of rules which would be part of the
Org format specification.

What about : allow mixing tabs and spaces only when indenting or
filling. One or more spaces everywhere[1] else.

An heading regexp would then be:

"^\\*\\+\\( +TODO\\)?\\( +\\[#.\\]\\)?\\( +.*?\\)?\\([ \t]+\\(:[[:alnum:]]_@#%:\\)\\)?[ \t]*$"

Note the use of [ \t]+ to fill the tags to the right. Also note that
regexp means "^***" is a valid regexp (which isn't the case actually).

Regards,

[1] As for every rule, some exceptions: check-boxes cookies and
counters, which can be sticked to respectively the headline text and the
check-box.

Agreed.

If you feel confident this is flexible enough, please go ahead.
We only need to make sure that a task like

* TODO Task       
           ^^^^^^ <= unintentional mixed tabs/spaces

is okay.  In other words: enforce a set of rules, but in a way
that will not surprise users if they accidently hit spaces or tabs
in position like the end of a line.

Yes, I think keeping "^***" as a valid regexp is a good idea.

Okay.

Thanks for looking again into this when you have some time!

Hi Nicolas

Org currently also uses \t before the tags, when it aligns them.

In fact, it isn't. "^***" shouldn't match an headline. Not yet
actually. If we want such headlines, org-outline-regexp and al. have to
be set to something like "\\*+". That would break many things, and
outline functions would match unexpected things, like *bold* at
column 0.

Anyway, here's another attempt to improve headline regexps consistency.

Subject: [PATCH] Provide more consistent regexps for headlines

* lisp/org-agenda.el (org-search-view): simplify regexp.
(org-agenda-get-todos): use new format string.
* lisp/org-archive.el (org-archive-all-done): simplify regexp.
* lisp/org-ascii.el (org-export-as-ascii): more accurate regexp.
* lisp/org-colview-xemacs.el (org-columns-capture-view): use new
  format string and new string.
* lisp/org-colview.el (org-columns-capture-view): use new format
  string and new string.
* lisp/org-docbook.el (org-export-as-docbook): more accurate
  regexp. Also use new regexp to match generic headlines.
* lisp/org-exp.el (org-export-protect-quoted-subtrees): more accurate
  regexp. Also use new regexp to match generic headlines.
* lisp/org-html.el (org-export-as-html): more accurate regexp. Also
  use new regexp to match generic headlines.
* lisp/org-mouse.el (org-mouse-match-todo-keyword): removed unused
  and now erroneous function.
* lisp/org.el (org-heading-regexp, org-heading-keyword-regexp-format):
  new variables.
(org-set-regexps-and-options): create regexps according to the
following rule: use spaces only to separate elements from an headline,
while allowing mixed tabs and spaces for any indentation job.
(org-nl-done-regexp, org-looking-at-done-regexp): removed variables.
(org-set-font-lock-defaults): fontify again headlines with a keyword
and no other text. Use new format strings.
(org-get-heading, org-toggle-comment, org-prepare-agenda-buffers,
org-toggle-fixed-width-section): use new format string.
(org-todo): more accurate regexps.
(org-point-at-end-of-empty-headline): simplify regexp.

This patch attempts to reduce the number of hard-coded headlines, by
providing two format strings and one generic string to cover most of
the cases of headline construction.
