That's the only supported way ...

... on Windows it might be possible to use app_init() from dia-app.dll, 
which is basically the old main function taking the command line argument 
count and the string array as parameters. But please remember that Dia is 
an application and not designed as an API for diagram processing.

Every Dia format except the native diagram format is useable via the second 
Dia language bindings [1]. See 
https://git.gnome.org/browse/dia/tree/bindings/test.py for an example 
script in Python.

The language bindings create with SWIG, which list CLISP as one of the 
supported target languages.  See: http://www.swig.org/compare.html

But you would probably need to write some Lisp specific code on your own.
