%% INITIALIZATION
%% ----------------------------------------------------------------------------
% Fonts are chosen in Preamble using \Set commands. But they are not activated
%   until \AtEndPreamble. Until then, the basic TeX font families must be
%   temporarily specified, so that certain packages can load without compliant.
% These are Latin Modern fonts, which are Open Type and will work, but are not
%   stylistically suitable for works of fiction. The only reason they are
%   used here, is because just about every TeX installation has them.
\gdef\rmdefault{lmr} % Latin Modern Roman
\gdef\sfdefault{lmss} % Latin Modern Sans
\gdef\ttdefault{lmtt} % Latin Modern Mono
% The following might become unnecessary if fontspec adds the capability to
% disable keys. For now: Color and Opacity cannot be used as font features,
%   for a black/white printed book. Alas, fontspec over-rules xcolor.
% So, this code over-rules fontspec:
\gdef\@CheckFontspecFeatures#1{%
  \@tempTFfalse%
  \IfSubStr{#1}{Color}{\@tempTFtrue}{}%
  \IfSubStr{#1}{Colour}{\@tempTFtrue}{}%
  \IfSubStr{#1}{color}{\@tempTFtrue}{}%
  \IfSubStr{#1}{colour}{\@tempTFtrue}{}%
  \IfSubStr{#1}{Opacity}{\@tempTFtrue}{}%
  \IfSubStr{#1}{opacity}{\@tempTFtrue}{}%
  \if@tempTF%
    \ClassError{novel}{Color and Opacity forbidden as font features}%
    {You defined a font, or added a font feature, with Color or Opacity. ^^J%
     That is disallowed in `novel' class.}%
  \fi%
} % end \@CheckFontspecFeatures
% Default font features (will be changed later):
\defaultfontfeatures{} % reset
\defaultfontfeatures{SmallCapsFeatures={Renderer=Basic},Ligatures=TeX,} % all
\if@novrevert
  \defaultfontfeatures[\rmfamily,\sffamily]%
    {Kerning=On,Numbers=OldStyle,Ligatures=Common}
\else
  \defaultfontfeatures[\rmfamily,\sffamily]%
    {Kerning=On,Numbers=OldStyle}
\fi
% Fake \microtypesetup until package loaded by \@ActivateFonts, \AtEndPreamble:
\newif \if@MicrotypeSet
\gdef\microtypesetup#1{
  \gdef\@mymicrotypesetup{#1} % used in novel-Fonts.sty
  \global\@MicrotypeSettrue
}%
%% end initialization


%% SETTINGS FOR PARENT FONT, DESCENDANTS, OTHERS
%% ----------------------------------------------------------------------------
% In `novel' you do not \usepackage{font name} or \RequirePackage{font name}.
%   You do not directly write \renewcommand\rmdefault{font name}.
%   You do not directly use \setmainfont[features]{font name}.
% Instead, `novel' requires a `parent font' to be set. The parent font is
%   the ancestor of the main (normal) font, and several other descendants.
% The parent font features, if any, should be a minimal set that will be
%   applied to all descendants. For example, if the font has an an alternate
%   style for a particular letter, and you want to use it for all descendants,
%   then you would spedify that feature for the parent font.
% For now, these settings are merely stored. Later, \AtEndPreamble,
%   the main (normal) font inherits the settings for the parent font.
%   Other descendants inherit those settings, with their own features added.
%   Anything not set by you, will have a suitable default set automatically.

% In a work of fiction, you probably do not need a sans or mono font.
%   But TeX expects you do have them. So, \AtEndPreamble, Libertinus Sans
%   and Libertinus Mono will be set as defaults, if you have those fonts.
%   Otherwise, Latin Modern Sans and Mono will be used, but they are not
%   well-suited to works of fiction.
% If you wish to set your own sans and mono fonts, do it using standard
%   `fontspec' syntax. There is no special method in `novel' class:
%   \setsansfont[features]{font name}
%   \setmonofont[features]{font name}

%% CREATING NEW FONT FONT FEATURES
%% ----------------------------------------------------------------------------
% \CreateFontFeature{substitutions}{feature code}
% Problem: Font has one or more alternate glyphs that you would like to use,
%   but they are not listed in a feature set for the font.
% Solution: Create your own feature set, with \CreateFontFeature. The created
%   feature may then be used like a real feature, in any font definition.
% The substitutions are a comma-separated list, char=char.alt and so forth.
% For example, the following substitutions are syntactically OK:
%   emdash=emdah.alt, one=one.rev, ntilde=ntilde.03
% If a substitution is not available in a particular font, it is ignored.
% You have to look at the font in a font editor, to know what is available.
% It is possible to make silly substitutions, such as a=b, five=three without
%   throwing an error, unless your code causes a cycle.
% The most useful application of this command is to reach alternate emdash,
%   and alternate oldstyle one. Not every font has these.
% The feature code is a 4-character pseudo- Open Type code, otherwise unused.
% For example, the feature code might be myfs (my fake substitution)
%   but it cannot be a pre-defined code such as lnum or smcp. It may be
%   a style set such as ss03 if you are sure that the font in question
%   do not already have ss03 (but this is taking a chance).
% Once defined, you may use it like this (for example):
%   \SetParentFont[RawFeature=+myfs]{fontname}
%   \NewFontFamily\myfake[RawFeature=+myfs]{fontname}
%   In the document body: {\addfontfeature{myfs} text}
\DeclareDocumentCommand \CreateFontFeature { m m } {%
  \IfEndWith{#1}{,}{\StrGobbleRight{#1}{1}[\@fakezero]}{\def\@fakezero{#1}}
  \def\@fakeone{"\@fakezero"}
  \StrSubstitute{\@fakeone}{=}{"]="}[\@fakeone]
  \StrSubstitute{\@fakeone}{,}{",\space["}[\@fakeone]
  \directlua{
    fonts.handlers.otf.addfeature {
      name = "#2",
      type = "substitution",
      data = {\@fakeone},
    }
  }
} %
