Can Pkg.activate("myPackage") be silent?

General Usage

Hello All

I have a silly little problem I can’t figure out. For internal reasons, I need to load my packages from a custom path with Pkg.activate("~/myPackage"). The thing is, we run it on the command line (here Julia 1.9 and PrecompileTools have been a life saver) but what is bugging us is the message it prints out. When we run
julia -e 'using Pkg;Pkg.activate("~/myPackage/"); using myPackage;RunMyCode()
it prints out
Activating project at ~/myPackage/myPackage`
is there any way to surpress this message, or do the same in a way that runs the code silently?

I know this is silly, but it bothers people here.

Thanks, Jack

Maybe

@nilshg Wow, yes, works perfectly. (I should have found that by googling, sorry)

Thanks, js

Most Pkg functions take an io keyword argument that allows redirecting their output (or suppressing it by redirecting to devnull):

$ julia -e 'import Pkg; Pkg.activate("/tmp", io=devnull); println("Hello!")'
Hello!

I think it’s unfortunate that Pkg API calls give these outputs; it should be enough to do that in pkg mode and with pkg-strings. In this particular case there’s an easy workaround though, use the --project flag:

julia --project=~/myPackage -e 'using myPackage;RunMyCode()'

I dont know how I missed that but is very logical. Thanks @ffevotte.

Thanks @GunnarFarneback, another good solution, now for the command line. And since almost all my code is run this way, very nice. As to your general point, I agree.
