Output from Base.find_package?

New to Julia

Hi all,

I have a question about the behaviour of Base.find_package.
I know package can be found :

  1. if the package is already installed.
  2. by using CSV

But when I follow this tuto: How to develop a Julia package for developing package, I get output from Base.find_package("YourPackageName") (without Pkg.add(pkg) nor using pkg).

I can’t get any clue from here (julia/base/loading.jl at master · JuliaLang/julia · GitHub)
Does anyone know what happened?

julia> using PkgTemplates
julia> t = Template(;
           user="your-GitHub-username",
           authors=["pywugate"],
           plugins=[
               License(name="MIT"),
               Git(),
               GitHubActions(),
           ],
       )

Considering this is in the “New to Julia” category, why do want to use Base.find_package at all? Please note that it is an internal function not part of the public interface (because it has no docstring). So what is it you want to achieve? Perhaps there is a better way of doing that :slight_smile:
