DepotDelivery bundles a Julia project into a standalone depot (contents of a `.julia/` directory).

• Bundles all Julia code of one or more projects.
• Can be deployed in air-gapped environments.
• Build for platforms other than the host platform.
• Can precompile all dependencies to built path.

build(src = pwd(), dest=mktempdir(); triplet, platform, verbose, precompiled)

Arguments:

• src = pwd(): A String/Vector{String} of the project path/paths containing Project.toml or JuliaProject.toml files.
• dest::String = <tempdir>: The depot directory to populate.
• platform::AbstractPlatform = <host platform>: The target Base.BinaryPlatforms.Platform.
• triplet = nothing: The target triplet of the platform to build for. If not nothing, it overrides platform.
• verbose = true: Whether to display verbose output during the build process (default is true).
• precompiled = false: Whether to enable precompilation of packages.

Returns:

• dest::String

using DepotDelivery
# `path/Project.toml` (or `path/JuliaProject.toml`) must exist
path = abspath(joinpath(pathof(DepotDelivery), "..", ".."))
depot = DepotDelivery.build(path)

Then in your production environment, either:

1. Replace the .julia/ directory with depot
2. Run include(joinpath(depot, "config", "startup.jl")) to begin your Julia session.

Be aware that build will copy everything inside the source directories to depot/dev/. Avoid populating those directories with unnecessary files. For example, when starting a new project, it's better to run julia --project=./isolated_folder/ rather than julia --project=., as in the latter case the Project.toml file will coexist with other stuff.

• Use any Base.BinaryPlatforms.AbstractPlatform as the platform or target triplet as the triplet.
• See Julia's supported OS/architectures.
• See ?Base.BinaryPlatforms.Platform and the types in Pkg.BinaryPlatforms for details, e.g.

import Pkg
Base.BinaryPlatforms.HostPlatform()
Base.BinaryPlatforms.Platform("windows", "x86_64"; cuda == "10.1")
# `arch` argument must be in (:x86_64, :i686m, :armv7l, :armv6l, :aarch64, :powerpc64le)
Pkg.BinaryPlatforms.Windows(:x86_64)
Pkg.BinaryPlatforms.MacOS()
Pkg.BinaryPlatforms.Linux(:powerpc64le)
Pkg.BinaryPlatforms.FreeBSD(:armv7l)
