ProgressMeter.next!(p; showvalues = [(:iter,iter), (:x,x)]) something like this?
The source code itself is quite short, seems like there is also a desc keyword argument you can pass to next!. See ProgressMeter.jl/ProgressMeter.jl at 83e619faed2780ab5d6929777c8f6151e3b88c5e · timholy/ProgressMeter.jl · GitHub
