Hi,
I have a patch like
[r $0_msg] | [print]
And would like to run Pd from command line (-nogui -send "....") and send something to the receive object.
How can I pass the '$0_msg' name in a way bash and Pd understand it?
Have tried different combinations of quotes and bars, but nothing works... :/
thanks! josé
$0 is a unique number that only the abstraction itself knows about. Typically you use it to keep things local. Just like you can't send a message to [r $0_msg] from another patch, you can't do it with "-send", either.
Just create a new patch, put your abstraction there and add a [receive foo] (without $0!) that will send the appropriate message to the abstraction. Now you can do
$ pd -nogui -send "foo 1"

you can send something to $0-xxx variables, but you should only do it if it makes sense.
I often create abstractions using $0 as an argument, such as [line-seg 1 2 $0], and then $3 in the abstraction is the same as $0 in the parent. if you really want, you can export the individual $0-values to a text file to be read in the command line. But is it necessary?

That's a common pattern, yes. Your example doesn't contradict my point, though: because [line-seq] can't access the parent $0 *), you have to pass it from the outside.
if you really want, you can export the individual $0-values to a text file to be read in the command line.
Please don't. $0 are potentially different every time you open the abstraction. Currently, they start with 1000 and increment monotonically, but this is really an implementation detail that you shouldn't rely upon.

I've proposed this https://github.com/pure-data/pure-data/pull/828/commits/31d293142ed186766a95...
which is even better as it expands symbols, so "$$0_something" gets expanded, I do this in my [else/dollsym] object.
the problem is that [receive] can't set its name yet, we also have PRs for that. Both of these would be very useful in these situations. I use it in my GUI abstractions to set built in send/receive names.
