Whitelist¶

Parsers are written in Elixir code but with a limited set of available modules and functions. This limitation is needed to ensure a stable operation of the platform.

In overall, all needed modules from the Elixir standard library are available which can be used for data access and transformation. System or operating related modules or sending messages is not available.

The following chapters document the currently available operators, keywords, functions and modules for writing parsers.

The main version of Elixir will be at least v1.13.
