Subject: Bug: inconsistent handling of empty duration cells in table [9.4.6 (9.4.6-12-gdcc3a8-elpa @ /home/jet/.config/emacs/elpa/org-20210816/)]

Message-ID: <CAF_DUeEFpNU5UXjE80yB1MB9xj5oVLqG=XadnkqCdzWtakWdPg@mail.gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 10772 bytes --]

When calc formulas producing empty strings are evaluated in the default
mode, an empty cell is produced. When evaluated in duration mode (U, T,
or t) a zero duration is produced. I feel the behavior should be
consistent with the number formats, producing a empty value instead of a
zero.

Test case:

| case         |   result |
|--------------+----------|
| default mode |          |
| default + E  |          |
| U + E        |    00:00 |
| T + E        | 00:00:00 |
| t + E        |     0.00 |
#+TBLFM: @2$2=string("")::@3$2=string("");E::@4$2=string("");EU::@5
$2=string("");ET::@6$2=string("");Et


Analysis: the problem (if it is a problem) is here:
https://code.orgmode.org/bzg/org-mode/src/master/lisp/org-table.el#L2616
The value produced for durations always comes from a call to
string-to-number, which returns 0 for empty strings.
org-table-time-seconds-to-string turns that into a zero duration
string in the requested format. An explicit test for an empty value here
fixes the issue.
