Please don't use the previous version of the multi-dimensional arrays!!!

First, I forget to get rid of one [drip] object. Second, I discovered that [pd drip] will create a stack overflow if there are more than ca. 300 elements! (Why???) So I replaced it with [list-drip] which works fine.

So here's the corrected pure vanilla version + a zexy version using [drip]. I prefer to use the latter one because it's waaaaay faster than all the drip abstractions based on [list split].

Vanilla: https://www.dropbox.com/s/wd0avxtaneqgdic/carray_vanilla.zip?dl=0

Zexy: https://www.dropbox.com/s/ea8kihwbdqhcajr/carray_zexy.zip?dl=0

PS: I did a benchmark test of iterating through an array of 1 million elements, using [realtime], and here's what I found on my system:

[array get] + [drip] --> ca. 6.5-9ms

[until] + [tabread] --> ca. 120-200ms

[array get] + [list-drip] --> ca. 340-400ms

To me this result was a bit surprising...

You can test yourself with the attached patch.

Wow, looks cool!

Just a few days ago I reworked some of my personal table abstractions, which also make use of the [array] object. However, some of them depend on zexy externals (I hope I didn't miss any other dependencies). I haven't shared them yet so the documentation is quite poor (no help files, docs inside the abstraction) and they look a bit messy. But maybe you can get some inspiration for your library... https://www.dropbox.com/s/xvj031korqw8guf/ctab-abs.zip?dl=0

Additionally I've been working on three basic abstractions for creating, setting and reading multi-dimensional arrays of any number of dimensions. They are pure vanilla style and even come with a help file :-D. (a object for array resizing is yet to be done...) https://www.dropbox.com/s/6xfgdyt697138e6/carray.zip?dl=0

Would be cool to hear your opinion on the multi-dimensional array stuff!

Thanks.

Yes. Right now I'm just looking to see if these would be useful, if there's anything awful about the syntax, if they try to do too much or are too fussy, if anyone would want to contribute, etc. When I get them polished a bit I'll do a regular release on the normal channels (I can't remember if I have access to anything officially Pd related).

db?

would you like to put those on a version control system of sorts, e.g.
the puredata svn or some publicly available git repository (e.g. github)?

(read as: please let us not go back to the dark ages, where code was
shared by sending files around by on floppy disks and you never new
which version was the current one)
