Hello all,  
I'm trying to embedd ruby, so far this is what I have:  
&nbsp;&nbsp;  
&nbsp;&nbsp;ruby\_init();  
&nbsp;&nbsp;ruby\_init\_loadpath();  
&nbsp;&nbsp;ruby\_script("embedded");  
&nbsp;&nbsp;rb\_load\_file("my\_script.rb");  
&nbsp;&nbsp;ruby\_run();  
&nbsp;&nbsp;/\* rest of my app here \*/

However, ruby is taking control of my code after calling ruby\_run, since it will always call "exit" after executing the code... is there a way to not exit after executing the ruby code?

thanks a lot,

This is by design ruby\_run() does not return. I imagine what you want to do is  
execute your script via rb\_protect(). You could take a look at  
[ruby embedded into c++](http://metaeditor.sourceforge.net/embed/) althought it is embedding ruby in C++  
much of what it talks about works for C.

How vim embedds ruby is good code to read too. Download the vim source  
code and look at if\_ruby.c

enjoy,
