pika::program_options::parsed_options
parse_environment(
    const pika::program_options::
        options_description&,
    const std::function<std::string(std::string)>&
        name_mapper)

Description

Parse environment. For each environment variable, the 'name_mapper' function is called to obtain the option name. If it returns empty string, the variable is ignored. This is done since naming of environment variables is typically different from the naming of command line options.

const pika::program_options::options_description&
