Hello, I am writing my first small package. I found Nemo useful for my purpose and I am using it in my package. But it comes with a small trouble: it prints a banner in the Jupyter notebook when it is loaded. Below is the code from Nemo where this happens. Would you see how to mute this banne…

I do things like this in similar cases: # Redirecting the output to /dev/null oldstd = stdout redirect_stdout(open("nul", "w")) [...] redirect_stdout(oldstd) # recover original stdout

Thanks sylvaticus! I can indeed redirect within my Juoyter notebook, this works: oldstd = stdout redirect_stdout(open("nul", "w")) using myPackage redirect_stdout(oldstd) Within myPackage I am using the Nemo package which is the banner emitter. However, if I move the redirect to within myPackage…

the redirection you made is run once during precompilation, therefore it has no effect on using myPackage. I suggest you open a issue in Nemo repository.

Yes, I have read that elsewhere. However, I did some tests and could not really clarify what it means. Besides, other people already opened an issue on Nemo, but it was rejected. So, either I have to live with it, or I have to hope for an unexpected solution, or I also could duplicate the Nemo pa…

If you have module AAA x = let println("setting x=2") 2 end end you should see “setting x=2” during precompilation, but not during using AAA. the value of x in the module is set once, and doesn’t need to be evaluated/changed at using. That is what precompilation is about. The only way of …

Thanks abulak At least I now understand exactly how this works ! Then it’s easier to live with it ! I will check if AbstractAlgebra.jl does “integer nullspace”. Probably yes, I just saw that it is the successot of Nemo.jl !!! Thanks a lot! Michel

[image] maajdl: I just saw that it is the successot of Nemo.jl !!! Where did you see that? Nemo.jl is still pretty much actual. It depends on AbstractAlgebra.jl, which sets up the interfaces and implements generic algebraic structures and algorithms. And Nemo.jl implement these interfaces on …

That’s how I understood this: AbstractAlgebra.jl grew out of the Nemo project after a number of requests from the community for the pure Julia part of Nemo to be split off into a separate project. found there: https://nemocas.github.io/AbstractAlgebra.jl/latest/ :smiley:
