Re: [Reuseware-devel] call external tool in composition program

[Jakob H. <jak...@tu...>]

Hi again,

It's not what it seems, I'm not talking to myself. Instead I talked to  
Steffen offline who pointed me in the right direction. New interpreters  
for the composition language can be added to  
de.tudresden.reuseware.fracola and registered in the corresponding  
plugin.xml file (but perhaps no-one should commit any drastic changes  
without checking with the people involved first? Which I guess is Sven  
now?) Anyway, I tried it on my local copy and it worked fine.

But, then it becomes interesting how one can extend the basiccl language  
into a specific composition language used for a specific DCS (dedicated  
composition system). For example, if I want a "callmytool" construct in  
the language in which I write composition operators for Modular Xcerpt,  
how do I extend the basiccl language into 'mybasiccl' so I only make  
modifications to this extension and not the core language (basiccl)?

The search continues...

Jakob
