Code inclusion is quite straightforward and simple: it evaluates the given source file in the context of the caller. Package loading is built on top of code inclusion and serves a different purpose. The rest of this chapter focuses on the behavior and mechanics of package loading.

Is Julia as fast as C?

Julia, especially when written well, can be as fast and sometimes even faster than C. Julia uses the Just In Time (JIT) compiler and compiles incredibly fast, though it compiles more like an interpreted language than a traditional low-level compiled language like C, or Fortran.

How do you load a package in Julia?

Package loading: e.g. import X or using X. The import mechanism allows you to load a package—i.e. an independent, reusable collection of Julia code, wrapped in a module—and makes the resulting module available by the name X inside of the importing module.

How is import X in Julia context dependent?

The meaning of X in import X is context-dependent: which X package is loaded depends on what code the statement occurs in. Thus, handling of import X happens in two stages: first, it determines what package is defined to be X in this context; second, it determines where that particular X package is found.

Why are package names not unique in Julia?

Because of the lack of a central naming authority, a single project may end up depending on different packages that have the same name. Julia’s package loading mechanism does not require package names to be globally unique, even within the dependency graph of a single project.

What does the pkg package manager do in Julia?

The Pkg package manager that ships with Julia lets you install and manage your projects’ dependencies. It assists in creating and manipulating project files (which describe what other projects that your project depends on), and manifest files (which snapshot exact versions of your project’s complete dependency graph).
