Hi, all. I have several .jl files. I want to pack them into a local module and install it into my environment via pkg. How can I make it?

There are some instructions on how to create a package in this documentation: [5. Creating Packages · Pkg.jl](https://pkgdocs.julialang.org/v1/creating-packages/)  
For the more basic structure of a `module` that is the base of a package, you can read the Julia documentation: [Modules · The Julia Language](https://docs.julialang.org/en/v1/manual/modules/)

Start with creating a project:

```bash
julia -e "using Pkg; Pkg.generate("My_Project)")"
cd My_Project
julia

```

This will create a small directory tree, including a Project.toml in the first level, which is what keep tracks of dependencies. In the `src` directory will be `My_Project.jl` as a `Hello, World.` Edit this to bring in your `.jl` files, which should all be functions

```julia
using Pkg
Pkg.activate(@ __DIR__ )
Pkg.add("DataFrames")
using My_Project
check_julia_version()
add_dependencies()
display_readme()

```

Edit `My_Project.jl`

```julia
include("src/utils.jl")
# etc

```

`utils.jl` and each other should end with

```julia-auto
export with_commas, with_percent # etc

```

Stay flat and bring everything into `My_Project` and avoid using macros in function definitions; reserve them for scripts. Otherwise, you will fall into circular dependency hell.
