Hello Guilers, I'm pleased to announce Guile-DSV 0.7.0: https://github.com/artyom-poptsov/guile-dsv/releases/tag/v0.7.0 This release replaces the old finite-state machine (FSM) implementation with the new one that uses Guile State Machine Compiler (Guile-SMC) [1]. The new FSM code is generated at build-time from PlantUML description directly. See the full list of user-visible changes below. As the result of re-writting FSMs of Guile-DSV with PlantUML/Guile-SMC, Guile-DSV gained some speed improvements. You can find an attached LibreOffice Calc document with some benchmarking using around 5 million lines of data (source: [2])
