Hi Katja,
Pd-l2ork has had a "clear" method for [delwrite~] for some time now.
Matju posted a simple patch for it on the Pd-list for someone who wanted it. In response to his posting, I did two things: a) pushed for its inclusion in Pd-extended, and
pushed for inclusion in Pd-l2ork. Here's how it broke down:
Pd-extended: witness a thread in which Hans and matju argue about who should post the patch on the tracker, listen to the sound of crickets for a few months, argue with IOhannes just to get him to click a button to assign the patch to Miller. Result: after years Pd-extended and Vanilla still don't have a "clear" method for [delwrite~].
Pd-l2ork: forward matju's patch to Ivica. He asks me what it's for. I tell him. He says, "Thanks." Result: Pd-l2ork has a "clear" method for [delwrite~] and I have my sanity.
