Or at least a link to a simple Lilv host example. Also, I don't see the URL of the SVN repo mentioned anywhere on the website. There's just a download link with tarballs. Please sign up and modify the site as you see fit, the entire thing (except of course generated docs and such) is a Wiki.

Would you believe, how cumbersome it's been to track, follow and install LV2 releases ? (The same unfortunately applies to some of your other apps, ingen, ...) Unreleased is unreleased. On purpose. Unreleased things are not *supposed* to be as widely distributed as released things, because they are not stable. Stable in this case does not mean it might crash, it means that everything related will break catastrophically in the future. They are not useful unless you are a developer seeking to participate in the implementation of a new extension, in which case you use SVN. There are all sorts of things in that repository that are rotten crap and most definitely should NOT be widely distributed and used. If it was release suitable, it would be released :P Extensions are not released until there are at least 2 independent working implementations of them. I think most would agree this is a good rule. For users, there are tarballs of all released extensions, and packagers have been doing their thing nicely with them. I don't see how it is any more cumbersome to track LV2 releases than any other project. Tarballs are released, and announcements are made. What is the problem? .., but I am not sure of the form this should take yet. A tar.bz2 with any script, that would build and install the whole LV2 devel stuff, including seldom used dependencies. Plus a README, listing additional dependencies. For example: I would not expect GTK+ to be included, but a required rdf-library I've never heard before... ... So, something like a waf script, and an INSTALL file, and a README file? Something like, oh I don't know, the ones that have been there ever since the repository was created? ;) A second tarball, including all currently known LV2 plugins. This could be called Official-LV2-plugin-pack_2011-08-01.tar.bz2 and could be updated regularly. I don't think it's appropriate or wise to create any such official thing. Plugins are written by diverse authors in diverse languages with diverse build systems. That's sort of the point. Anyone is welcome to create a meta-package, though, and it would be nice in some cases, but that is a much more messy task than doing so for extensions, since there is no standard format for plugin sources (nor could there be). The scope of plugins is much wider than this wish implies. For example, LinuxSampler is a known LV2 plugin these days. Ingen will be as well. Including these things in such a release is clearly inappropriate. I think actively maintaining, hosting, distributing, and guiding the development of *extensions* is a job that lv2plug.in should strive to do, to keep the LV2 ship sailing straight, so to speak. Plugins, however, are independent projects. The point of a good plugin specification is to enable independent developers to implement whatever plugins they see fit. Centralization is not a win. Thank you for this effort. You're welcome. Making your work more accessible is much appreciated. Don't assume that developers actually *want* everything to be accessible ;) I assure you several developers are actively working to design, solidify, implement, and release new extensions that will provide us with new advanced plugin capabilities as quickly as possible. -dr ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev

2011/7/6 David Robillard d...@drobilla.net: For users, there are tarballs of all released extensions, ... Tarballs are released, and announcements are made. What is the problem? The problem is: tarballs is plural. For LV2 you have to download x tars, compile, install and when you're finally done, your new LV2-plugin still doesn't compile, cause it would have needed an experimental extension... my experience so far. Ah right. I should wait for the final release ;) A second tarball, including all currently known LV2 plugins. This could be called Official-LV2-plugin-pack_2011-08-01.tar.bz2 and could be updated regularly. I don't think it's appropriate or wise to create any such official thing. Plugins are written by diverse authors in diverse languages with diverse build systems. Centralization is not a win. I thinks it can be. I'm not talking about centralizing different projects, but *final* distribution centralization, a kind of central mirror for spread projects. Take ladspa as an example: There are X websites with ladspa-packages, containing diverse plugins. Now every maintainer (and interested user) has to track those sites, downloading from X locations... My thought: If there was a central collecting point, most maintainers could simply download one tar and make the content ready for their distro. Plugin creators would also benefit: They simply would have to send their current sources to the collecting point, knowing it soon became public and spread. I think actively maintaining, hosting, distributing, and guiding the development of *extensions* is a job that lv2plug.in should ... do .. So maybe my request should have gone to that address. Don't assume that developers actually *want* everything to be accessible ;) I assure you several developers are actively working to design, solidify, implement, and release new extensions that will provide us with new advanced plugin capabilities as quickly as possible.
