Pkg operations without updating registry

General Usage
2

There is a PR for an “offline mode”: https://github.com/JuliaLang/Pkg.jl/pull/1265 but needs to be updated for the new artifact system etc.

Edit:
Sorry I misread, you just don’t want to update the registry.

  1. You can delete the .git folder inside the registry to stop it from updating, but then you have to remember to manually update when you need/want to.
  2. You can set Pkg.UPDATED_REGISTRY_THIS_SESSION[] = true.
  3. You can use GitHub - fredrikekre/jlpkg: A command line interface (CLI) for Pkg, Julia's package manager. where option 2 is default. E.g. $ jlpkg add Example would not update the registry.

Note also that on Julia 1.5 (and also Julia 1.4 if you set JULIA_PKG_SERVER="pkg.julialang.org") Pkg will just download the registry without using git, so that should also help.
