Reproducible examples in blog posts

When migrating this blog recently from Hugo to Franklin.jl, the main difficulty I faced was reproducing old examples (so effectively I didn't rerun anything, and just moved the old generated HTML pages). I have been bothered by this for a long time, so I wrote a quick hack which I packaged up in ReproducibleLiteratePage.jl.

This page was processed using that package. Here is how it works:

1. take a Julia code file marked up with Literate.jl,

2. add a Project.toml and a Manifest.toml (eg activate the directory as a project and add packages)

3. produce a markdown file using ReproducibleLiteratePage.compile_directory().

Here is some code:

using UnPack # the lightest package I could think of
struct Foo
    a
    b
end
@unpack a, b = Foo(1, 2)
a, b

(1, 2)

The Julia source (again, marked up with Literate.jl), Project.toml, and Manifest.toml should be available as a tar archive at the bottom of the page.
