PV1 Neo

Version: PV1 Neo v0.1.0
Last Update: 2024-06-20
Status: Active Development
POS Compliancy (Estimate): 60%

Windows-only front-end for Parcel NExT, a visual programming platform. This implementation is targets lightweight usage, beta tests, and covers only subset of POS features. It's node-only Windows-only and doesn't support advanced graph-native constructs. It would suffice for the purpose of concept development, testing libraries and showcasing the core software aspects of Parcel workflows. This setup also directly embeds the Ama runtime, and (at least in beta tests) make direct reference/dependency on available toolboxes (packages).

PV1 is implemented using WPF, it uses single-process model (contrast to server-client model) and the graph editor is not as flexible as Gospel, so it may not support full sets of (front-end) capabilities of Gospel. Despite that, we try as much as possible to be full POS-compliant. Below table summarizes main capabilities of PV1 when compared to other front-ends.
