[L2Ork-dev] $0 weirdness

[Albert Graef]

Hi Ico,

any thoughts on how to resolve this issue? Should I report it as a bug? If
you don't see the issue, then maybe my previous report didn't sound urgent
enough. ;-)

I understand that compatibility with other Pd flavors is not a major
concern for you. But we're not talking about some incompatibilities in the
external library here. Rev. 57914b7 makes the Pd-L2Ork *patch file format*
incompatible with all other Pd versions. It completely kills
interoperability with both vanilla and extended Pd (and even older Pd-L2Ork
versions!).

In fact, rev. 57914b7 affects pretty much *all* abstractions. If you have a
nontrivial patch, chances are that you'll get bitten by this change ($0-id
receivers are a very common idiom). The DISIS patches included with
pd-l2ork are affected as well (check disis_wiimote-help.pd some time).
Moreover, a quick search of pd-l2ork/extra turns up some two dozen
abstractions with #0- in them. So even Pd-L2Ork's own abstraction library
is pretty much broken right now. I can't believe that I'm the only one
running into this.

I consider this a very serious bug. IMHO rev. 57914b7 needs to be reverted
quickly. For the time being, I have a new PKGBUILD for Arch Linux systems
ready to go which patches the current git sources accordingly. This will
eliminate the issue for Arch users, but this really needs to be fixed
upstream. ;-)

Best,
Albert
