Hello,
the reference to the last row @0 led to incompatible changes:
* spreadsheet: relative reference to same row
(using Org mode version 6.15d)
The Org mode version 6.15 introduced @0 as a reference to the last
row for spreadsheet (org-table) formulas. This leads to problems if
you used it as reference to the same row before.
- description from [[http://orgmode.org/Changes.html][Org-mode list of
user-visible changes]]:
Spreadsheet references to the last table line.
You may now use @0 to reference the last dataline in a table in a
stable way.
- according to [[info:org:References]]:
`0' refers to the current row and column. Also, if you omit
either the column or the row part of the reference, the current
row/column is implied.
However this doesn't work since @0 refers to the last line.
If you press `C-c *' with the cursor inside the tables below, the
second column should contain the doubled value of the first.
** @0 refers to last line
|---+---|
| 1 | 4 |
| 2 | 4 |
|---+---|
#+TBLFM: $2=2*@0$-1
this has worked before as reference to the same row, now it refers
to the last row
** bug: omitting explicit reference
|---+--------|
| 1 | #ERROR |
| 2 | #ERROR |
|---+--------|
#+TBLFM: $2=2*$-1
this seems to be a bug, should refer to the same row
** @+0 refers to same row
|---+---|
| 1 | 2 |
| 2 | 4 |
|---+---|
#+TBLFM: $2=2*@+0$-1
works as expected
Greetings,
Stephan

The distinction between @0 and @+0 would work, too, but is rather confusing and hard to remember. I think both should represent either the last or the current row.

However, I will still reverse the change that introduced @0 as a reference to the last line. The risk that someone will be bitten by this is too high, and @0 is really too similar to @+0, so I think the distinction is not large enough. I will try to find a different solution, like @last$2 or so, but this is harder to implement and will take a little while. Sorry Matt. The reason why I am in a hurry to revert this change is, among others, because Emacs 23 might go into pretest very soon, and I really want a clean, good version to ship with it. - Carsten On Dec 18, 2008, at 5:50 PM, Stephan Schmitt wrote: > For me the new behaviour is fine, if leaving out the row > specification works. > > The distinction between @0 and @+0 would work, too, but is rather > confusing and > hard to remember.

(Call it org-use-new-spreadsheet-semantics). If it is nil, whenever the new syntax is used, raise a warning. The warning could be: 1. just a message to the echo area 2. inserted into the top of the updated table 3. an error which aborts spreadsheet calculations This pushes the responsibility onto users to check their tables before they set the option. So I'm thinking it's unfair to make that an org-wide setting... More thinking... Another option is to include a file only variable like this #+ORG_VERSION: [6.2]-- or #+ORG_VERSION: --[6.2] The first option would cause old versions of org-mode to abort processing, and the second would cause new versions to abort. This might help with any and all future changes to syntax, and perhaps allow users to mark the files they don't want to change yet. Perhaps, if they are careful, they'll be able to load a different version of org-mode to process an individual file. I'm reminded of something I had learned about perl, long ago. If Carsten and community like this, perhaps someone could suggest the most elisp like way of doing version comparisons. Failing that, I'd suggest looking at the perl way of doing it, which allowed for multiple dots in the version string 1.0 < 2.0 < 3.0 < 10.0 < 20.0 < 100.0 and 1.0< 1.1 < 1.2 < 1.100 < 2.0 I think (but can't remember) that version numbers had to have pairs of digits (1.1.1 was illegal you had to use 1.1.1.0). There must have been a reason OR I'm wrong about the requirement. Just my musings On 2008-Dec-18, at 16:25, Carsten Dominik wrote: > You are right, this is an incompatible change.
