Open sourcing a library: how hard can that be?
summary
Library reads Diablo II Resurrected save files, written for Java 21 and solving C-style null-terminated strings, bit/endianness bugs and changing patch formats; uses records not Lombok, OpenRewrite for migrations and AssertJ for tests. It exposes a read-only parser that calculates item and set bonuses, ships an optional Quarkus standalone streamer app and is published to Maven Central with GPG signing after choosing LGPL; publishing is harder than coding but the release works and small user base (~20k players, ~100 streamers) uses it.
