[PD-announce] Re: Re: wavview: a waveform viewer for Pd

thanks Rolf,

yes I noticed the plot errors, I've just managed to clear them (I'll fill
an issue about this maybe, and about some other data-structures problems,
e.g there's a crashing bug when using text fields in pre-allocated arrays).
The solution I found is to delete-then-recreate the subpatch containing the
problematic "element" template (here [pd template-bar], and [pd
template-mark] for the timeline).

As for the name... yeah, I don't like [wavview/wavview_timeline] either. It
should probably just be [wavview/timeline], but I didn't like the idea of a
naming clash with other possible [timeline] libraries. OTOH that won't
happen without [declare -path wavview].
In that case I have to use [wavview/timeline] in the help patches (so that
you can copy/paste it anywhere else), so I'm gonna refactor my repo and put
the patches in a wavview/ subdir (and add a hidden [declare -path ..]).

Maybe I will overwrite v0.3 in Deken.

EDIT: done. I replaced v0.3.

sidenote: I experienced a mail rejection when I first answered to rolf. The
error was:

so I redirected to [email protected], hope it works now.
