Developping non registered packages should i always do dev package

using Pkg
Pkg.add("PackageName")
using PackageName

Option 1: Using the `dev` command

If you are developing a package that is not registered in the Julia package registry, you can use the `dev` command to add it to your project. This command allows you to develop the package locally without the need to register it.

using Pkg
Pkg.dev(path_to_package)

Replace `path_to_package` with the path to the directory where your package is located. This will create a development version of the package in your Julia environment.

Option 2: Using the `Pkg.clone` function

If you prefer to clone the package from a remote repository, you can use the `Pkg.clone` function. This function allows you to specify the URL of the package repository and will download and install the package in your Julia environment.

using Pkg
Pkg.clone("https://github.com/username/PackageName.git")

Replace `https://github.com/username/PackageName.git` with the URL of the package repository. This will clone the package and make it available for use in your Julia environment.

Option 3: Using the `Pkg.develop` function

If you want to develop a package that is already registered in the Julia package registry, you can use the `Pkg.develop` function. This function allows you to specify the name of the package and will download and install the latest development version of the package in your Julia environment.

using Pkg
Pkg.develop("PackageName")

Replace `PackageName` with the name of the package you want to develop. This will download and install the latest development version of the package in your Julia environment.

Among these three options, the best choice depends on your specific needs and preferences. If you are developing a package locally and do not plan to register it in the Julia package registry, using the `dev` command is a convenient option. If you prefer to clone the package from a remote repository, the `Pkg.clone` function is a suitable choice. Finally, if you want to develop a package that is already registered in the Julia package registry, the `Pkg.develop` function is the recommended option.
