Re: [bug] export corruption bug and 3 more bugs

Re: [bug] export corruption bug and 3 more bugs

[Samuel Wales]

Minimal .emacs and test case for export corruption bug.

In the process, I found 2 Emacs 22 incompatibilities (fixed in the
minimal .emacs -- I had already fixed them) and 1 args out of range
error (not fixed -- can somebody find this bug?).  There is no stack
trace.

The args out of range error occurs when you do c-c c-e A on the lowest
level headline.

The corruption bug occurs when you export the top level of the test case.

I wanted to post my blog today, but I don't know which org version to
roll back to to make sure it will work, and for health reasons can't
afford the typing for git bisect.

Thanks.

Okay, I can reproduce the args out of range with Emacs 22. Turns out
that `regexp-opt` behaves different when creating
`org-babel-result-regexp'.

(regexp-opt org-babel-data-names)

encloses the regexp for babel data names in a shy grouping construct
in Emacs 23

(regexp-opt org-babel-data-names) => "\\(?:DATA\\|RES\\(?:NAME\\|ULTS\\)\\|TBLNAME\\)"

While it does not in Emacs 22

(regexp-opt org-babel-data-names) => "DATA\\|RES\\(?:NAME\\|ULTS\\)\\|TBLNAME"

Thus the literal string "results" in the example file is matched by
Org Babel in `org-exp-res/src-name-cleanup'.

Looks like setting up `org-babel-result-regexp' should do a check for
the Emacs version and explictly add the shy grouping construct if
version < 23 -- I'm really not familar with all the Babel parts so Cc:
Erik Schulte who I assume knows Babel better than me.

I'll check the other (compatibilty) problems during the weekend.

Best,

Re: [bug, babel] export corruption bug and 3 more bugs

[Samuel Wales]

Hi David,

Thank you.  I am unable to debug this further so I appreciate it.

Is it necessary to construct this regexp for babel if babel is not used?

Were you able to reproduce the corruption bug?  Did anybody else?
Emacs -Q, minimal test case.

(I'm trying to warn the world about one definitely-already-existing
global pandemic of an AIDS-like disease that nobody has heard of but
is 2x the size of AIDS in the USA -- and a possible global pandemic
10x the size of HIV -- but my normally-sublimely-excellent software is
dropping random lines.  :/  Hmm, should I switch to talking about
Justin Bieber and use Microsoft Word instead?  :)  We could hand out
soma with Word and tell people it's just as good as Org.  :))

Samuel

P.S.  Please feel free to put the compatibility fixes into org-compat
or wherever.

That's LOTS of keystrokes.

I've just pushed a fix for compatibility with Emacs22 and the
`activate-mark' function.

I suppose I reproduced the corruption bugs: It's the Babel regexp
problem.

Suppose so. A temporary work-around could be

(setq org-babel-data-names nil)

before you load Org. This will cause Babel to not create the offending
regexp.

Hi David and Eric,

Reverting the following fixes the export corruption bug for me.

Hi David,

Sorry it took me a while to notice this thread -- incidentally after a
patch to this effect was shared by Lawrence Mitchell in a separate
thread.  I've just applied Lawrence's patch, which should resolve this
issue as well.

Please let me know if the problem remains.  Now that this thread is on
my radar I should be more attentive to it.

Thanks -- Eric

Thanks Eric, David.  Test case and .emacs seem to work for it so far.

To anybody: I noticed that the region stays active after export.  Is
this intentional?

Thanks.

Great, thanks for confirming.

I have no idea, but it seems to me it is better to preserve the active
region than eliminate it.
