In a recent patch we have introduced names for all fields in the last
row. This has lead to a bug, that Org thinks there might be a field
formula associated with those fields. Now we check if there really is
one, and only in this case ask to overwrite it with a column formula.
Report by Henry Atting.
After the failed implementation of `@0' as a reference for the last
line, this is a second attempt to provide such references. I would
have liked to allow `@last' as the reference, that would have been
beautiful. However, too many regular expressions directly search for
`@' followed by a number, so this is too hard to implement.
Therefore, I am now turning the last row into a row of implicitly
named fields. From now on, $LR1, $LR2,... can be used to refer to
fields in the last row. These names may also appear on the left hand
side of formulas.
Exporting tables to LaTeX suffered from the problem that Org tables
are often long, but that the tabular environment in LaTeX cannot
handle long tables. This patch fixes this issue.
LaTeX export can now deal with very long tables, by setting an option
in the "ATTR_LaTeX:" line. Also, you can specify the alignment by
hand. Here is an example:
Also, table export now correctly deals with tables that start with a
hline. In such a case, also the LaTeX version will have this extra
hline before the first line.
The last data line in a table is often a line with important data, for
example sums of a column. In tables with varying length, the row
number of this line is constantly changing, which makes it hard to
write programs creating tables and then installing formulas.
This patch introduces @0 as a special reference to the last row, so
that @0$3 would be the field in the last row, 3rd column.
Tassilo Horn asked for this, because he finds the default behavior of
silently choosing a different row too confusing. I actually do agree.
The main use of this feature was running averages, if you need this
feature, you can customize the variable
`org-table-error-on-row-ref-crossing-hline'.
This key needs special treatment, because it needs to work *outside*
tables. The patch introduces a special command to call the
creation/conversion function if there is no conflicting binding to
`C-c |' outside of orgtbl-mode.
S-SPC did lead to an error in orgtbl-mode, because there is no binding
to this key. Now orgtbl-self-insert-command falls back on calling
self-insert-command for such cases.
RET did fail in orgtbl-mode, if the cursor was at the beginning of the
buffer. Now it opens a new line whenever the cursor is at the
beginning of a line, and that includes the beginning of the buffer.....
These are changes that where made in the Emacs CVS.
The change in org-publish is not final, it is still being
discussed - however, the current change should make it possible
to compile and run the code with the latest CVS version of Emacs.
