Hi all,

Does the XMLRPC::Server class from Ruby’s xmlrpc lib automatically  
provide a method to list all available methods being served? Or do I  
have to roll that myself?

Thanks,

Dan

It does include it, but the xmlrpc documentation makes it difficult to  
find. It’s hidden in the `BasicServer` class. The method is called  
`addIntrospection`:

[http://www.ruby-doc.org/stdlib/libdoc/xmlrpc/rdoc/classes/XMLRPC/BasicServer.html](http://www.ruby-doc.org/stdlib/libdoc/xmlrpc/rdoc/classes/XMLRPC/BasicServer.html)

It adds:

- `system.listMethods`
- `system.methodSignature`
- `system.methodHelp`

which are the defacto xmlrpc standard for introspection.
