* Adding new table rows/cols in a formula update

Hi.

Suppose I have this .org file:

 |   |
 #+TBLFM: @1$2=5

It's a 1x1 table with a formula. The formula sets a cell that's out of
bounds in the table, so evaluating this formula results in an error. How
set-in-stone is this behavior? I haven't dug too deeply into the code,
but are there fundamental assumptions here? Would a patch that extends
the table before applying such a formula be too naive in some way?

Thanks!

Here's a tiny patch that adds the columns (not rows) as needed. Is this
reasonable?

I would include a customization variable to control this behavior, defaulting to whatever the current behavior is:
IE:
(setq org-calc-extend-file nil) default system behavior
(setq org-calc-extend-file t) always silently extend rows
(setq org-calc-extend-file "warn") issue warning in message buffer that line was extended
(setq org-calc-extend-file "prompt") prompt user y/n on whether or not to extend column

Your commit message is missing information and "TINYCHANGE" at its end.

What about `org-table-formula-create-columns'?

> +  "Non-nil means that evaluation of a field formula can add new
> +columns if an out-of-bounds field is being set."

First line needs to be complete. E.g.,

  "Non-nil means a field formula can create a new column."

> +  :group 'org-table-calculation

You need to add :version and :package-version keywords.

Is this check really necessary? Doesn't `org-table-goto-column' already
figures it out before creating a new column?

OK. Added. By the way, I signed the copyright-assignment paperwork for
Emacs itself. Would I need to do this again for org-mode?

Sure, why not.

OK. I'm not sure what those values should be, so please double-check.

This is necessary if we want to be able to warn the user or to prompt
them ONLY if a new column has to be made. I.e. if we're not looking past
the bounds of the table the user should never be pestered. If the
customization variable is only t/nil then this can be dramatically
simplified, as you have observed.

By the way, is (org-display-warning) the preferred way to produce a
warning? It does into a new buffer, not into *Messages*.

Tweaked patch attached.

Does it need sanity checking? A typo in a formula can create "billions
and billions"[fn:1] of columns inadvertently.

Thanks. It looks good.

Would you mind providing a test for it in org-test-table.el and an entry
in ORG-NEWS?

    * org-table.el (org-table-formula-create-columns): New variable.
    (org-table-recalculate): Use the new org-table-formula-make-new-cols

Thanks for your work on this, the patch looks good but it cannot be
accepted as a "tiny change".  Would you be willing to sign the FSF
copyright assignment papers?

If yes, please fill in the form from here:

That part of the test, specifically the attempt to catch the error is
not working for me on Windows, most likely because I use an older
version of Emacs there (I don't recall which one, either 23.4 or 24.1 I
think).  This probably comes about because ert-deftest is a macro, but I
don't have time right now to dig into it.

Achim.

It turns out that older Emacsen throw 'error rather than user-error, so
you need to catch both.  Fixed in 82599d3 on master.
