Hello
I have found a bug with clock tables and even have localized the exact point in org-clock.el
where it occurs. I don’t know enough of the Org Mode code base to figure out the best solution and submit a patch.
The general symptom is that if:
org-update-all-dblocks
added to org-export-first-hook
with the goal of ensuring that dynamic blocks are current before every export; ANDC-c C-e 1 b
(buffer/subtree export)
The Mark terminating the end of the region to be exported is carried into the org-clocktable-write-default
formatting function and the call of (backward-delete-char 1)
on line 2352 oforg-clock.el
deletes a region (between the Mark of the initial call and point, which is immediately before the #+END:
construct of the clock table). Deletion of the #+END:
construct malforms the clock table and ultimately the export fails leaving the Org file is a corrupt state.
Launch Emacs clean:
/Applications/Emacs.app/Contents/MacOS/Emacs -Q
Add the update to org-export-first-hook
by evaluating the follwing line in *scratch*
(add-hook 'org-export-first-hook 'org-update-all-dblocks)
Report versions (note this report is done from the non-Git-HEAD Org 7.8.09 included with Emacs, but the problem also exists in HEAD):
M-x emacs-version GNU Emacs 24.1.50.1 (x86_64-apple-darwin, NS apple-appkit-1038.36) of 2012-04-27 on bob.porkrind.org M-x org-version Org-mode version 7.8.09
Open the following test file
* Project A Clock summary at [2012-04-27 Fri 14:30] | Headline | Time | | |--------------+--------+------| | *Total time* | *2:59* | | |--------------+--------+------| | Project A | 2:59 | | | Task A1 | | 2:00 | | Task A2 | | 0:59 | ** Task A1 CLOCK: [2012-04-26 Fri 11:58]--[2012-04-26 Thu 13:58] => 2:00 ** Task A2 CLOCK: [2012-04-27 Fri 09:00]--[2012-04-27 Fri 09:59] => 0:59 * Project B ** Task B1
Export the entire buffer as a baseline test
C-c C-e b
The result is as expected:
Clock Summary
line changes to reflect the current time (showing that org-update-all-dblocks
) ran correctlyPut the cursor on the Project A line and attempt to export just the Project A subtree
C-c C-e 1 b
The expected result is a (smaller than before) valid HTML export.
The actual result is:
org-map-dblocks: Dynamic block not terminated
in the echo area#+END:
and Project B are deleted from the file resulting in the following invalid Org file#+STARTUP: showeverything * Project A #+BEGIN: clocktable :maxlevel 2 :scope subtree Clock summary at [2012-04-27 Fri 14:15] | Headline | Time | | |--------------+--------+------| | *Total time* | *2:59* | | |--------------+--------+------| | Project A | 2:59 | | | Task A1 | | 2:00 | | Task A2 | | 0:59 | * Project B
Tracing through org-clock.el
I found the culprit on line 2352, if I add a (debug)
statement immediately before that line I see the following:
C-c C-c
on the #+BEGIN:
line) the debugger enters and there is no region highlightedtest.org
from the end of the table (Point) to the end of the entire Project A
subtree (Mark, from the selection made by the export subtree code)
