Low level File format access for Samuel Harmon's PrismScroll .prism files
I find rolling random treasure for D&D 5e campaigns to be a chore. The tables in the DMG are clunky and don't contain new content in later core rule books, not to mention adventures. So, it seemed like a iPad app or similar might be nice. Such things are pretty easy to write. The problem is the database of extant magic items. We use the FightClub 5e app for much of our D&D games, and it has one such database associated with it here on github that it can import. Alas, the database doesn't include the "rarity" tag, which is rather important for a random treasure generator.
I recently found Samuel Harmon's PrismScroll and PrismScrollDM apps. These are in active development and have a similar database hiding off in a discord channel. He also keeps a .prism file for the SRD with the app in the Resources subdirectory. Alas, it isn't quite XML and without newlines was rather painful to look at in depth, but was simple enough in structure to reverse engineer in a few hours. Now, I can read it. It has a "rarity" tag. Yay!
The attached code (compatible with PrismScroll 6.22.0 to my limited testing) can read the .prism file and produce a hierarchy of C++ objects corresponding to sets, arrays, key-value pairs, strings, bools, ints and doubles. It can print them out in a more human readable form. It is also capable of taking such trees and writing a .prism file that diffs without loss against the original, at least for the two .prism files I looked at, the included SRD file in the app and the larger basic one from Discord. (It needed testing.)
