Scripting. Pd-Lua allows you to write your own Pd externals, so you can
quickly create your own objects which can do more than what you can do with
just Pd (using the full power of a real programming language). You can also
do that with C, of course, but Lua is much easier.

Is there the possibility to make it compatible with newer lua versions

Not sure, you'll have to ask IOhannes. He maintains the earlier version in
Debian, and we all know how fast that moves. :)

to have it integrated as a working external depending on LUA version?

My fork should still work with Lua 5.2 as well, Lua 5.1 isn't supported in
either version AFAICT (there have been some incompatible changes in the
language). I wouldn't want to use anything earlier than Lua 5.2 anyway.

Besides: How stable is the purring data by now? :)

Quite. You might want to package 2.6.0 which has been out for a while, see
https://agraef.github.io/purr-data/. I have a PKGBUILD for the git version
in the AUR, it should be easy to adjust this for a stable release.
Dependencies galore, though. ;-)

True. But it's still being used, as it's the recommended way to do both
2D/3D graphics and video with Pd. I'm currently testing a build of Purr
Data with Gem based on the latest git, and so far it works fine on Arch for

We could politely ask IOhannes (he's the current maintainer) to put out a
new release. I'll mail him right away.

Apart from that, we don't really have a naming scheme for pd externals.

Has there ever been a PKGBUILD for it?

I thought so, might be quite some time away, but maybe I'm mistaken. Or
maybe it went away after the big AUR4 house-cleaning.
