IIRC Inform 7 .i7x is internally translated to Inform 6 .i6t source which is more low-level C-like language. Have a look at code pieces formatted as (- ... -) in installed Inform extensions. You can mix 6 and 7 together. BTW I tried to feed some Inform 7 code to APE[1], which is a parser of an English subset written in Prolog, without much success as I recall. As for existing IF tools the first come to mind are Twine and Ren'Py. [1] https://github.com/Attempto/APE https://github.com/Attempto/APE
