table/calc: subscr() fails with date

table/calc: subscr() fails with date

[Karl Voit]

Hi!

I've found a bug when using subscr() to get the value of the previous
row. With the following date values, it fails and I don't have an idea
why:

| date                   | previous date          |
|------------------------+------------------------|
| [2015-08-21 Fri 16.57] |                        |
| [2015-12-30 Wed 11:08] | [1986, Fri, 16.57]     |
| [2016-02-01 Mon 18:33] | <2015-12-30 Wed 11:08> |
| [2016-03-01 Tue 19:01] | <2016-02-01 Mon 18:33> |
| [2016-04-01 Fri 19:39] | <2016-03-01 Tue 19:01> |
| [2016-05-01 Sun 13:01] | <2016-04-01 Fri 19:39> |

| [2016-09-02 Fri 15:34] | <2016-08-01 Mon 19:18> |
#+TBLFM: @3$2..@>$2 = subscr(@<$1..@>$1, @# - 1)

Do you have any hint or idea?


At my side: Org-mode version 8.3.4 (release_8.3.4-33-gd522fc)

There is a typo above.

The fact that inactive time stamps are turned into active ones is
because Calc only handles the latter. So all inactive time stamps are
turned into active ones prior to evaluation.

Dammit!

I swear I thought of a typo by myself and I overlooked it a couple
of times. Embarrassing :-|

Thanks for clarifying this one as well. I thought so but it's better
to get it acknowledged by a pro ;-)
