Release Notes

  • v0.5 (2017)
    • The old way of making processes is deprecated in favor of the semi-coroutine approach as implemented in ResumableFunctions. The @process macro replaces the @coroutine macro. The old @process macro is temporarily renamed @oldprocess and will be removed when the infrastructure supporting the produce and the consume functions is no longer available in Julia. (DONE)
    • This version no longer integrates a continuous time solver. A continuous simulation framework based on DISCO and inspired by the standalone QSS solver using SimJulia as its discrete-event engine can be found in the repository QuantizedStateSystems (WIP):
    • Documentation is automated with Documenter.jl (WIP: Overview and Tutorial OK).
  • v0.4.1 (2017)
    • the @resumable and @yield macros are put in a seperate package ResumableFunctions:
    • Users have to take into account the following syntax change: @yield return arg is replaced by @yield arg.
  • v0.4 (2017) only supports Julia v0.6 and above. It is a complete rewrite: more julian and less pythonic. The discrete event features are on par with v0.3 (SimPy v3) and following features are added:
    • Scheduling of events can be done with Base.Dates.Datetime and Base.Dates.Period
    • Two ways of making Processes are provided:
    • using the existing concept of Tasks
    • using a novel finite-statemachine approach
    • A continuous time solver based on the standalone QSS solver is implemented. Only non-stiff systems can be solved efficiently.
  • v0.3 (2015) synchronizes the API with SimPy v3 and is Julia v0.3, v0.4 and v0.5 compatible:
    • Documentation is available at readthedocs.
    • The continuous time solver is not implemented.
  • v0.2 (2014) introduces a continuous time solver inspired by the Simula library DISCO and is Julia v0.2 and v0.3 compatible.
  • v0.1 (2013) is a Julia clone of SimPy v2 and is Julia v0.2 compatible.
