How to set environment for local Julia package in module

Gaussia, here’s a workflow that performs well for my needs.

After adding Revise to your default v1.X environment, in a ~/.julia/config/startup.jl file, have the following:

using Pkg
if isfile("Project.toml") && isfile("Manifest.toml")
    Pkg.activate(".")
end
try
    using Revise
catch e
    @warn "Error initializing Revise" exception=(e, catch_backtrace())
end

Now, make a package for a project.

cd ~/Documents
julia -e 'using Pkg; Pkg.generate("example")'

cd example
julia -e 'using Pkg; Pkg.activate(".");Pkg.instantiate()'

ls -l
Manifest.toml
Project.toml
src   <-- your module lives in this subdirectory

touch playground.jl  <-- your project script

ls -l
Manifest.toml
playground.jl
Project.toml
src

ls -l src
example.jl  <-- your module

Once this is set up, when julia is launched in the example directory, it should use the example project as the environment. Any packages added in the session should then be available to the playground.jl script or the example.jl module via a using X line in those files.

Your default v1.X environment, launched outside the example directory, should have only a couple packages used everywhere, such as Revise or Infiltrator. Remove other packages added by mistake to that default environment.
