Watch this space for more details.π£οΈ Jacob Wang: Difflicious - Diffs for humans and AI agents
Scala is used in applications with complex domain logic,
and with that often means big comparison failures that is difficult to decipher.
Difflicious is a Scala library/toolkit for diffing Scala objects:
- Structured diff results pin-points the parts of the objects that are different
- Configurable diffing methods (e.g. Compare a List order-independently)
In this talk, we'll walk through Difflicious' various features and show you how
it can improve your development workflow (and your AI agents', too!)β Jacob Wang β
Jacob has been writing Scala for close to 10 years. He enjoys creating programs that mostly
behave, as well as sharing this joy via open source & teaching.π£οΈ Mystery speaker: mystery talk
