What does BestieTemplate do?

Creating Julia packages involve the creation and edition of many tiny files. Wouldn't it be great to automate this?

This is exactly what BestieTemplate does.


  • How is BestieTemplate different from PkgTemplates?
    • it can be applied to existing packages
    • it invites to follow some (opinionated) best practices
    • it can be reapplied to acquire updates made to the template
    • it is automatically reapplied through Pull Requests made by the Copier.yml workflow (Work in progress)


Under the hood, BestieTemplate is no more and no less than:

  • a copier template/skeleton for Julia packages (see folder template); and
  • a package that wraps copier in Julia using PythonCall.


Install BestieTemplate in your chosen environment (we recommend globally) by entering pkg mode by pressing ] and then:

julia> # press ]
pkg> add BestieTemplate


julia> using BestieTemplate
julia> BestieTemplate.generate("path/to/YourNewPackage.jl")
julia> # or BestieTemplate.apply("path/to/YourExistingPackage.jl")

please note that "YourPackage.jl" can either be a fresh new package or an existing one.

Here is a list of links/repos that include content that we have used for inspiration, or used directly. This is most likely not a complete list, since many of the things included here were based on existing packages and knowledge that we brought from other projects. This also doesn't explain where each file came from or why they are here. You can find some of that information in the Explanation section of the docs.

  • PkgTemplates.jl, naturally. We used it for many years, and in particular for the initial TulipaEnergyModel.jl commit (see below).
  • Netherlands eScience Center's python template includes many of the best practices that we apply here. We used many of the ideas there in a Julia context, and took many non-Julia specific ideas from there.
  • TulipaEnergyModel.jl was the project that motivated this version of a template. From the start we decide to implement many best practices and so we started from a PkgTemplates.jl template and started adding parts of the python template that made sense.
  • The Julia Smooth Optimizers package ecosystem was one of the main motivations to look for a solution that could be applied and reapplied to existing packages, in particular to help maintainers.
