A real editor for After Effects expressions.
eXLib brings worker-based semantic analysis, AE-specific type intelligence, and real-time validation to the AE expression engine — targeting the actual V8/ES2018 runtime AE ships, not generic JavaScript.
This documentation covers the internal beta. eXLib is not publicly released.
