Functions generated at runtime without world-age issues or overhead

RuntimeGeneratedFunctions.jl

RuntimeGeneratedFunctions are functions generated at runtime without world-age issues and with the full performance of a standard Julia anonymous function. This builds functions in a way that avoids eval.

Note that RuntimeGeneratedFunction does not handle closures. Please use the GeneralizedGenerated.jl package for more fixable staged programming. While GeneralizedGenerated.jl is more powerful, RuntimeGeneratedFunctions.jl handles large expressions better.

Credit to Chris Foster (@c4tf) for the implementation idea.

Example

using RuntimeGeneratedFunctions
RuntimeGeneratedFunctions.init(@__MODULE__)

function no_worldage()
    ex = :(function f(_du,_u,_p,_t)
        @inbounds _du[1] = _u[1]
        @inbounds _du[2] = _u[2]
        nothing
    end)
    f1 = @RuntimeGeneratedFunction(ex)
    du = rand(2)
    u = rand(2)
    p = nothing
    t = nothing
    f1(du,u,p,t)
end
no_worldage()
