Standard library reference

The standard library is the Pepper runtime: the files under runtime/ that every program is compiled with. The pages listed first (from Built-in functions to URI) are the prelude, available without an import. Each module after them (io, async, json, …) is brought in with an import, such as import io or import [File, Path] from io; its other pages are listed under it.

These pages are generated from the doc comments in the runtime’s source (see Documentation comments), so they always match the version of Pepper they were built with. Use the version picker at the top of the page to read the reference for another release.
