Hi,
after following the discussion about the new BABEL syntax I was under
the impression that the following should work to set two variables in
one PROPERTIES drawer:
:PROPERTIES:
:var: foo=1
:var+: bar=2
:END:
However, the definition of bar is ignored. It turns out that there can
only be one :var: or :var+: entry in a drawer and the latter can only be
used to append to inherited entries, but not to those defined in the
same drawer. Is this the intended behavior? How would I define multiple
variables in a drawer (except for putting them all on one line)?
Thanks,
Viktor

You are correct, I believe this is a bug. I've just pushed up a fix, so
your example above should now work as expected.
Thanks,

Hi Eric,
thanks for your input. I just pulled the latest code from git and while
my original example works, the following does not:
:PROPERTIES:
:var: foo=1
:var+: bar=2
:var+: baz=3
:END:
#+BEGIN_SRC sh
echo foo: $foo
echo bar: $bar
echo baz: $baz
#+END_SRC
If I evaluate the source block I get the following error in the messages
buffer:
=: Args out of range: "", 0
The following works:
:PROPERTIES:
:var: foo=1
:var+: bar=2 baz=3
:END:
#+BEGIN_SRC sh
echo foo: $foo
echo bar: $bar
echo baz: $baz
#+END_SRC
There also appears to be a difference between quoted and unquoted
values and commatas. E.g. the following works
:PROPERTIES:
:var: foo=1
:var+: bar="2", baz=3
:END:
#+BEGIN_SRC sh
echo foo: $foo
echo bar: $bar
echo baz: $baz
#+END_SRC
If I remove the quotes around 2 I get the following error:
ad-Orig-error: reference '2,' not found in this buffer
On the other hand, the following version does not produce an error, but
the value of $baz is not set.
:PROPERTIES:
:var: foo=1
:var+: bar="2",
:var+: baz=3
:END:
#+BEGIN_SRC sh
echo foo: $foo
echo bar: $bar
echo baz: $baz
#+END_SRC
Cheers,
Viktor

Yes, the comma results in the 2 not being parsed as a number, which
means that it will then try to be understood by Babel (which thinks
first of a reference unless the value is wrapped in quotes indicating it
is a string). The moral is to not give references purely numerical
names.

Thanks for your fix. The above example now works for me.
However, I've noticed a problem with inheriting var properties. They are
inherited in a child task only if the child task itself has no var
property. Is this the intended behavior? See the example below.
Cheers,
Viktor
* Parent task
:PROPERTIES:
:var: foo="1"
:var+: bar="2"
:END:
** Child task without own properties
#+BEGIN_SRC sh
echo foo: $foo
echo bar: $bar
#+END_SRC
#+RESULTS:
| foo: | 1 |
| bar: | 2 |
** Child task with own properties
:PROPERTIES:
:var: foo="a"
:END:
#+BEGIN_SRC sh
echo foo: $foo
echo bar: $bar
#+END_SRC
#+RESULTS:
| foo: | a |
| bar: | |

Yes,
The example below is the intended behavior. The property mechanism is
not tailored to variable setting, but is rather a general mechanism for
the concatenation of property strings. Any property specification
unless it is postfixed with a "+" will /reset/ the value of that
property to its current value.
However try replacing
> :var: foo="a"
with
> :var+: foo="a"
which is valid and should work for your use case below.
There are still some lingering issues with inheritance and Org-mode
properties which I may try to address one of these days.

I'm not sure if I understood you correctly, but even if I replace "var"
with "var+" in the child's property drawer, the value of bar that is set
in the parent task is not available in the child task.
