Re: [LAD] How to develop guis for LV2?

The second part may be opinion, and no argumentation is provided, but still I see no reason to ban it. I have two questions to the LV2 consortium (by which I mean the group of developers actively advocating LV2). Q1. On the LV2 website, Lars Luthman's UI extension is described as: "This extension is written for revision 2 of the LV2 specification and is NOT compatible with revisions 3 and later. Do not implement this extension in new plugins or hosts, and do not expect it to work in old ones. It is only available here for archaeological purposes." Even in its short life LV2 has managed to create some archeology. So AFAICS, there is no GUI extension except the one using a separate process which does not really scale very well to large numbers of plugins (and which as Gordon already mentioned is provided in simpler form by DSSI). Which leads to my question: if everything can be done by extensions, as is the recurring mantra, why was whatever revision 3 provides not implemented as an extension to revision 2 ? Of course this would have led to the first example of two extensions being mutually incompatible, something which is a real risk but conveniently ignored in all LV2 propaganda. Q2. Would the LV2 consortium accept an extension that would: - if required by a plugin, be the only one, but unconditionally, - completely replace LV2's 'base', including the initialisation and process calls, the port descriptions in an external file, and whatever else by some other mechanism ? Such an extension would effectively embed a completely new plugin standard into LV2, leaving only the plugin discovery and packaging mechanism. Supporting it would be no more complex than supporting e.g. both dynparams and port groups, so there's no technical rationale for refusing such an extension. There could be an ideological one of course. But if that is enough to refuse an extension, then ideological attacks on LV2 are legitimate as well.
