I created three branches on my personal public org-mode repo on GitHub.

- ob-lua
- ob-php
- ob-redis

https://github.com/stardiviner/org-mode

Hope maintainer can merge those branches.

Hi,

Thanks for your patches.

Some comments follow.

First, do you have copyright assignment to the FSF or would you be willing
to?  This is necessary to merge the patches.  Please refer to,

      http://orgmode.org/worg/org-contribute.html

Second, could you send your work as patches?  I.e. use git format-patch.
Note the format of the commit message should be in the ChangeLog format
(refer to the link above).

Thanks,
Rasmus

I tried to sign the FSF copyright assignment before, but it is very
difficult for me. So I give up. Is there other ways to merge this patches
without signing the assignment? (I can give up this right)

Second: I updated branch commit messages in the ChangeLog format.

Normally you "only" need to sign a piece of paper and send it by snail
mail to the FSF office in the US of A.  But you may be referring to the
terms of the assignment.

Depending on the issues you faced, it might be best to discuss them with
assign@gnu.org, who will have the legal knowledge to give you proper
advice.

Meanwhile, your files could be added to contrib, which does not require
you to do the paperwork.  Contrib files are not part of Emacs and would
not come as part of the default Org package.  To me, Contrib is more
convenient than MELPA, but I’m not sure everyone would agree.

It is easier than this - it can be done via email. Print sign and scan (photograph w/ phone), or don't even print and just sign digitally.

  -k.

Isn’t this only available to residents of the USA?  Maybe not.  It would
be cool if it’s generally available now.

Hm. I don't know. It didn't occur to me that the signature process was different based on where someone lives, but that may be the case.

I moved files to contrib/lisp/. I live in China, hope FSF can assign the
copyright assignment digitally.

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

     https://immerrr.github.io/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.

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.

Re: add some babel supports (PHP, Lua, Redis)

I modified most part of my files.

- There are some places I can't improve because I'm not good at elisp.
(maybe other      people can improve it later) Like ob-redis.el implement
ob-sql style configuration. and ob-lua.el make use of lua-mode's running
process.

- I guess ob-php.el is the only one branch can be merged.
- Anyway, check out my updates, if no one can be merged, I will still keep
my github repositories.

Thanks for your detail reviews.

OK.

Maybe we should wait until it is a bit less bare-bone or there’s a
copyright assignment in place.

BTW there’s also this ob-php,

  https://github.com/steckerhalter/ob-php

Note that there was already one ob-lua.el that was never commiteed for
some reason...

I see, I will check out them, and merge them if possible.
I will PR after they are good enough.
