Pkg3

Next-generation package manager for Julia. Still quite alpha.

First, Pkg.clone the Pkg3 repo itself to install it:

clone("https://github.com/JuliaLang/Pkg3.jl.git")

Now load Pkg3 in Julia 0.6 to add packages and load them. Packages will be installed to joinpath(homedir(), ".julia", "packages"), so they won't influnce the packages that you already have installed.

a> using Pkg3

This gives you a pkg> REPL mode, activated (for now) by the ] key. Currently, this supports three operations: add, rm and up:

 add JSON
: Resolving package versions
: Cloning [682c06a0-de6a-54ab-a142-c8b1cf79cde6] JSON

Package operations create a Project.toml file that record what dependencies your project (or named global environment) has ? i.e. what you've explicitly added. It also creates a Manifest.toml file that records the exact versions of each of those dependenices and their transitive dependencies ? and the graph between them. You can load top-level dependencies via the usual using JSON or import JSON constructs in the REPL or in Julia scripts.
