class rosidl_cli.command.hash.extensions.HashCommandExtension(name: str)

The extension point for source code generation.

The following methods must be defined: * generate_type_hashes

generate_type_hashes(package_name, interface_files, include_paths, output_path)

Generate type hashes from interface definition files.

Paths to interface definition files are relative paths optionally prefixed by an absolute path followed by a colon ‘:’, in which case path resolution is to be performed against that absolute path.

Parameters:

  • package_name – name of the package to generate source code for

  • interface_files – list of paths to interface definition files

  • include_paths – list of paths to include dependency interface definition files from.

  • output_path – path to directory to hold generated source code files

Returns:

list of paths to generated source files

rosidl_cli.command.hash.extensions.load_hash_extensions(**kwargs)
