There is also https://github.com/lanl-ansi/juniper.jl , but it hasn’t been ported to the new JuMP yet, it is a work-in-progress.

It seems like Alpine is also not updated.

ASTInterpreter2 is not a dependency of either package. This is probably related to Juno. See ERROR: Unsatisfiable requirements detected for package ASTInterpreter2 [e6d88f4b].
