Hi,
Thanks for your patches. Sorry about the delay. I was hoping that
someone with more ob knowledge would step in.
Please find some comments below. I think some more work is needed before
your libraries are

Maybe,
The file provides Org-Babel support for evaluating Lua code.

This is unnecessary. Ob implies Org.

It seems that ob languages do not typically define new groups.
Also, ob is the filename. Variables are org-babel.

I don’t think this is necessary to have as a defcustom. There’s already
:session. Also, you are missing :type. Per above, group is org-babel.

This is normally not autoloaded. Babel languages are loaded via
org-babel-do-load-languages.

Is something missing here? AFAIK cmd → "lua -" always.
Also, what if my lua is not in my PATH? I got a felling that you might
make a more robust mode by hooking into lua-mode

How are various return values handled? E.g. will a table be correctly
interpreted as such? (It’s a while since I coded in lua).

This should be unnecessary as the lua-mode is presumably lua-mode. Also,
I think your code depends on lua-mode in order to be able to edit it. You
need to declare that as a dependency.

:Type is missing and this buffer should not be a defcustom.

See comments above re docstring, and robustness.
What sort of return values can I expect from this? I don’t know php, but
I assume it’s mainly "log messages".

Unnecessary. Also, it seems there’s an undeclared decency on some sort of
php mode.

Does redis support login and different ports and all that jazz?
If so, please compare the configurability to the needs of ob-sql.
Is it possible to extend ob-sql with another engine? (I don’t know
anything about redis).
Or are these "NoSQL" databases similar enough that it would be possible to
have "unite" them in a single library. Does ob have support for any
"NoSQL" databases ATM?
I’m not implying that this is necessarily the right way to go. I’m just
trying to understand the nature of this.

My guess is that connectivity support is not comprehensive enough.
