FGenerators.jl is a package for defining Transducers.jl -compatible iteration protocol (aka extended foldl) with a simple Python-like @yield-based syntax. Quoting FGenerators.jl README, here are a few examples for creating ad-hoc “generators”: julia> using FGenerators julia> @fgenerator function …

Hi, This is such a fantastic package - thank you for creating it. I was successfully using it for some time , including earlier today, until a recent update to 1.7.2 and now receive the following issues: ▶ errors the manifest for the project is (I’ve omitted non - relevant packages since I exceeded…

Looking at the stacktrace, I’m going to guess that this is due to FLoops.jl’s change in 0.2: https://github.com/JuliaFolds/FLoops.jl#update-notes . By default @floop for ... is (mostly) always parallel. However, FGenerators.jl is not parallelizable by default. You can use SequentialEx() as in @floo…

Hi, Thank you very much for reviewing the error and responding so quickly - that did indeed work in the sense that results are now being returned again! It has made me think that to extend this to work with the parallel form might be a bit of a challenge given the error message. Would you advise w…

See https://github.com/JuliaFolds/FGenerators.jl#defining-parallelizable-collection for how to make @fgenerator parallelizable. [image] djholiver: Would you advise writing this without the use of the @fgenerator macro and instead creating via the Transducer library proper? @fgenerator is a v…

Thanks - I’ll give it a go! Regards
