%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Adding languages
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% To add captions for other languages:
% 1. Copy and paste languages/_template.sty to languages/<language>.sty
% 2. Substitute the <language> token in the file with the language name
%    (i.e. \addto\captionsfrench).
% 3. Replace the English strings with the translations and comment any captions
%    that you do not translate. Please keep the captions in the same order.
% 4. Add \RequirePackage{lib/languages/<language>} to the following function.
\cs_new_protected_nopar:Npn \__rpg_input_languages:
  {
    \RequirePackage{lib/languages/italian}
    \RequirePackage{lib/languages/japanese} % Requires LuaTeX or XeTeX
    \RequirePackage{lib/languages/ngerman}
    \RequirePackage{lib/languages/russian}
    \RequirePackage{lib/languages/spanish}
    \RequirePackage{lib/languages/french}
    \RequirePackage{lib/languages/portuguese}
}

% Delay loading captions until after the user has imported a language package.
% Enables using babel/polyglossia with the rpgbook document class as well as the
% rpg package.
%
% Both language packages use \AtBeginDocument. Use \AtEndPreamble (etoolbox)
% instead to side-step load order issues.
\AtEndPreamble{
  % Check if either babel or polyglossia have been loaded,
  % in which case load the string captions
  \@ifpackageloaded{babel}{
    \__rpg_input_languages:
  }{}
  \@ifpackageloaded{polyglossia}{
    \__rpg_input_languages:
  }{}
