Detailed Description

A localizable message.

The translation and formatting of the message is delayed until displaying it to the user. This allows the user to change the language while the application is running.

Constructor & Destructor Documentation

txt()

template<typename... Args>

hi::v1::txt::txt ( std::string msg_id, Args &&... args )

inlinenoexcept

Construct a localizable message.

It is recommended to use the parentheses form of the constructor so that it will look like a function which is recognized by the gettext tool.

Parameters

msg_id	A English string that is looked up in the translation database or, when not found, as-is. The msg_id may contain placeholders using the std::format format. Plurality is based on the first std::integral arguments.
first_arg	The first argument passed to std::format().
args	Arguments passed to std::format().

Member Function Documentation

operator bool()

constexpr hi::v1::txt::operator bool ( ) const

inlineexplicitconstexprnoexcept

Check if the message is in use.

translate() [1/2]

gstring hi::v1::txt::translate ( std::locale const & loc = os_settings::locale(), std::vector< language_tag > const & languages = os_settings::language_tags() ) const

inlinenoexcept

Translate and format the message.

Find the translation of the message, then format it.

Parameters

loc	The locale to use when formatting the message.
languages	A list of languages to search for translations.

Returns

The translated and formatted message.

translate() [2/2]

gstring hi::v1::txt::translate ( std::vector< language_tag > const & languages ) const

inlinenoexcept

Translate and format the message.

Find the translation of the message, then format it.

Parameters

languages

A list of languages to search for translations.

Returns

The translated and formatted message.
