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.

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

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.

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 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.

Best,

Re: [O] Setting multiple variables for code blocks in one property drawer

2012-02-15 Thread Viktor Rosenfeld
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

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.

[O] Setting multiple variables for code blocks in one property drawer

2012-02-09 Thread Viktor Rosenfeld
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
