Hi,

could not find ob-csharp in org mode. I created one to make the pointy 
haired boss happy.

It's based on Eric's ob-java.el with some bits taken from other ob files.

It works for the simple examples following below.

Hope this is useful and I'm open for hints to improve the code.

Thanks for your contribution.  I hope the pointy haired boss is happy :)

Please give some thought to exactly how you'd like to contribute
ob-csharp.  See http://orgmode.org/worg/org-contribute.html

It can live in core, contrib, or as an emacs package.

I'm not sure who makes decisions about Babel code these days, but
someone will step up when you choose your path.

All the best,
Tom

When it lives in core, it is available to everyone who downloads
Emacs. That is valuable because some users never install a single
package.

But it requires csharp-mode, which is not part of GNU Emacs.

Re: ob-csharp

[thomas]

Thanks for the quick replies.

I'd really like to contribute to core, if that's possible (practically, 
I did nothing though; I just stripped Eric's ob-java and changed a few 
lines).

As Rüdiger pointed out csharp-mode is not part of Emacs.
But I'm not sure if csharp-mode is really necessary (besides syntax 
highlighting in the org buffer).

We might leave it out?

Re: ob-csharp

[thomas]

well allright. I did some tests and think csharp-mode is not necessary. 
So I guess it would be OK to leave it out. Can anybody confirm?

Thank you for the library. You can contribute to core as long as you
have signed FSF papers.

Hi,

I'm sorry, I could not find the time yet to figure out how to 
"officially" contribute to Emacs (the papers are signed, though).

In the meantime you can find ob-csharp on github:
