如何为xtext创建自定义终端语法？

Question

My grammar file is already too large and is causing the error: The code for the static initializer is exceeding the 65535 bytes limit.

So, I want to split my grammar into 2 xtext files, and create a separate custom terminal.xtext to lower down the size of my grammar file.

I have an xtext project in org.xtext.rpcIDL, where my RpcIDL.xtext is in its src directory. I have read here that its possible to have 2 grammar files in one project. But I cannot add another grammar file in my current project. When I right-click, then go to New, there is no option there to add a new xtext file.

How can I add a custom xtext file in my project?

I don't know if you already found out the solution by yourself but in case you didn't:
To create a new Xtext-File in your project right click in your org.xtext.rpcIDL which should be in your text-project under src (The one with the package symbol in front of it), then go to New->File and then you just have to give it a name and add the extension .xtext . That will add the xtext-nature to your project. After that you have to add the line grammar ... (just copy this line of your other file and change the last element to the name of your new File). Then add with and enter the name of your other xtext-file (this is the one which stands after the generate in your other file. Then you should be able to use the elements of all the features which you have declared in your original File.
I hope I could help you.
