Is there a way to get the contents of pkg.julialang.org in machine-readable form (JSON/XML)? I mean not only the list of packages (this can be obtained at METADATA.jl repo). But also the versions of Julia supported, the test status for different versions of Julia, etc.
If you look on that site, there’s a link to the repository and script that’s used to generate the HTML source: https://github.com/JuliaCI/PackageEvaluator.jl/tree/master/website. Depending on your needs, you should be able to either adapt that script, or you could send a pull request to have the generated JSON hosted along side the HTML.
