Module loading

Base.require is responsible for loading modules and it also manages the precompilation cache. It is the implementation of theimport statement.

Experimental features

The features below are experimental and not part of the stable Julia API. Before building upon them inform yourself about the current thinking and whether they might change soon.

Package loading callbacks

It is possible to listen to the packages loaded byBase.require, by registering a callback.

loaded_packages = Base.PkgId[]callback = (pkg::Base.PkgId) -> push!(loaded_packages, pkg)push!(Base.package_callbacks, callback)

Using this would look something like:

julia> using Examplejulia> loaded_packages1-element Vector{Base.PkgId}: Example [7876af07-990d-54b4-ab0e-23690620f79a]
