% set a(foo) 1
1
% trace variable a r {puts a ;#}

a

I would like to see the trace fire when
I read from baz.

Logged In: YES user_id=80530 Joe, you were asking about this on the chat. dgp added on 2002-06-25 00:09:53: Logged In: YES user_id=80530 Thanks. If this is to change, it would be a FR/TIP. Don't feel strong enough about it to do that now, but I'll shift this over the FR tracker in case anyone else wants to pick it up. Note to self: read *all* relevant man pages before filing bugs... Workaround seems to be to set traces on both the source and target of the [upvar]. Works fine, then, if annoying. msofer added on 2002-06-24 23:56:38: Logged In: YES user_id=148712 upvar.n dixit: "If otherVar refers to an element of an array, then variable traces set for the entire array will not be invoked when myVar is accessed (but traces on the particular element will still be invoked). In particular, if the array is env, then changes made to myVar will not be passed to subprocesses correctly." So, is this a bug or a FR? Does it need a TIP? | |||
