template<typename OptionList >

std::string evgen::SingleGen::presentOptions ( OptionList const &  allowedOptions, bool  printKey, std::initializer_list< typename OptionList::value_type::first_type >  exclude  )

staticprivate

Returns a string describing all options in the list.

Template Parameters

OptionList

type of list of options (e.g. std::map<int, std::string>)

Parameters

allowedOptions	the list of allowed options
printKey	whether to print the key of the option beside its name
excludeKeys	list of keys to be ignored (none by default)

Returns

a string with all options in a line

The result string is a list of option names, separated by commas, like in `"'apple', 'orange', 'banana'". IfprintKeyistrue`, the key of each option is also written in parentheses, like in `"'apple' (1), 'orange' (7), 'banana' (2)"`.

template<typename OptionList >

auto evgen::SingleGen::selectOption ( std::string  Option, OptionList const &  allowedOptions  ) -> decltype(auto)

staticprivate

Parses an option string and returns the corresponding option number.

Template Parameters

OptionList

type of list of options (e.g. std::map<int, std::string>)

Parameters

Option	the string of the option to be parsed
allowedOptions	list of valid options, as key/name pairs

Returns

the key of the Option string from allowedOptions

Exceptions

std::runtime_error

if Option is not in the option list

The option string Option represent a single one among the supported options as defined in allowedOptions. The option string can be either one of the option names (the matching is not case-sensitive) or the number of the option itself.

OptionList requirements

OptionList must behave like a sequence with forward iterators. Each element must behave as a pair, whose first element is the option key and the second element is the option name, equivalent to a string in that it must be forward-iterable and its elements can be converted by std::tolower(). The key type has no requirements beside being copiable.
