In actuality something like what like WinPAWS by Douglas Harter would be awesome, but a cross platform executable would be optimal... Minus the redundant registration bs.NGPaws
by Carlos Sánchez might be for you? PAWS inspired, no registration, and compiles to web browsers!
Concerning the OP, I'm afraid the answer is not. You're stuck with PAWS technical manual, which explains quite a few things, but not them all, and not in a way meant for creating a proper reimplementation (but is a good starting point if you feel ready to figure out the rest reinverse-enginering on your own).
Anyway, Mr Tim Gilberts have lately been active on rescuing his old Gilsoft related stuff, take a look at 8-bit blog HERE
. I know for certain he is busy struggling to recover his more obscure early works, but dropping a line might prove useful!
Thanks everybody for the answers, I suspected that what I was looking has never been done... there are many projects PAWS related, the mentioned ngPaws, the couple paguaglus/superglus (two spanish tools which are based on PAWS but compile to Glulx VM), but no reimplementation.
One that aimed to be as much compatible as possible would be great, it could even be interfaced with current output systems for the Z-Machine and bring PAWS games to the web, smartphones... I know we have emulators of all the machines PAWS supported and we can play the games that way, but this is not the same as having a working cross-platform interpreter.
I'll try to contact Mr. Gilberts, thanks to the links above I see he has been active lately, even seems to have preserved a disk missing from the DAAD (a multi-platform PAWS-like parser he tailor-made for a Spanish company) distribution!
