a quick and dirty tool for generating `Project.toml`

GenProject.jl

module GenProject

using Pkg

export genproject

    isfile(fname) || throw(ErrorException("Directory $dir lacks a REQUIRE file"))

    pkgs = Any[]
    for line ∈ eachline(f)
        pkg = split(line)
        first(pkg) == "julia" && continue
        if length(pkg) > 1 && !use_latest
            push!(pkgs, Pkg.PackageSpec(first(pkg), VersionNumber(last(pkg))))
        else
            push!(pkgs, Pkg.PackageSpec(first(pkg)))
        end 
    end 
    pkgs    
end
