This document describes the configuration files of the different packages.
AEA configuration YAML
The following provides a list of the relevant regex used:
PACKAGE_REGEX: "[a-zA-Z_][a-zA-Z0-9_]*"
AUTHOR_REGEX: "[a-zA-Z_][a-zA-Z0-9_]*"
PUBLIC_ID_REGEX: "^[a-zA-Z0-9_]*/[a-zA-Z_][a-zA-Z0-9_]*:(0|[1-9]\\d*)\\.(0|[1-9]\\d*)\\.(0|[1-9]\\d*)(?:-((?:0|[1-9]\\d*|\\d*[a-zA-Z-][0-9a-zA-Z-]*)(?:\\.(?:0|[1-9]\\d*|\\d*[a-zA-Z-][0-9a-zA-Z-]*))*))?(?:\\+([0-9a-zA-Z-]+(?:\\.[0-9a-zA-Z-]+)*))?$"
