Modules and packages

Every .fb file is a module, which shows other files only what it marks Public. A package is a folder with a project.toml, which names it and lists the packages it depends on, from a folder on disk or from a registry. These tutorials go from a program in a few files to a package that others can add to their own projects.

Tutorials

4. project.toml Make a package with fb new, name its modules by its name, and set what project.toml controls.
5. Using packages Depend on a package from a folder or from the registry, pin its version in fb.lock, and update it.
