ConTeXt：使用附加的非标准样式、替代和大小定义字体

Question

如何定义具有其他非标准样式、替代和大小的字体？例如，这些字体：

鸬鹚[1][2]

• 样式：Cormorant、Garamond、Infant、SC、Unicase、Upright
• 备择方案：细体、细斜体、常规、斜体、中体、中斜体、半粗体、半粗斜体、粗体、粗斜体
• 尺寸： 文本

錦[3]

• 样式：单色、无字体、窄无字体、衬线字体、窄衬线字体
• 备择方案：常规、斜体、粗斜体
• 尺寸：文字，标题

利伯提努斯[4]

• 样式：单色、无衬线、衬线
• 备择方案：常规、斜体、半粗体、半粗斜体、粗体、粗斜体
• 尺寸：文本，显示

继ConTeXt 参考手册[5] 以及ConTeXt：字体粗细[6] 这个网站上的答案，我试过了（阅读评论，它们很重要）：

% I don't know if features go with `definetypeface` or `definefontsynonym`. The
% reference manual shows it both ways. Perhaps it is a MkII vs MkIV thing?
\starttypescript [cormorant]
    \definetypeface[cormorant] [rmcm] [serifcormorant]  [cormorant] [default] [features=default]
    \definetypeface[cormorant] [rmgm] [serifgaramond]   [cormorant] [default] [features=default]
    \definetypeface[cormorant] [rmif] [serifinfant]     [cormorant] [default] [features=default]
    \definetypeface[cormorant] [rmur] [serifupright]    [cormorant] [default] [features=default]
    % Right, so these two are both provided as uppercase-only font files. Since the
    % fonts come this way, we don't need to use `features=smallcaps` to switch
    % smallcaps on. Right?
    \definetypeface[cormorant] [rmuc] [serifunicase]    [cormorant] [default] [features=default]
    \definetypeface[cormorant] [rmsc] [serifsc]         [cormorant] [default] [features=default]
\stoptypescript

% Do this for each style:
% ...
\starttypescript [serifcormorant] [cormorant] [name]
    \definefontsynonym [SerifLight]             [name:CormorantLight]
    \definefontsynonym [SerifLightItalic]       [name:CormorantLightItalic]
    \definefontsynonym [Serif]                  [name:CormorantRegular]
    \definefontsynonym [SerifItalic]            [name:CormorantItalic]
    \definefontsynonym [SerifMedium]            [name:CormorantMedium]
    \definefontsynonym [SerifMediumItalic]      [name:CormorantMediumItalic]
    \definefontsynonym [SerifSemiBold]          [name:CormorantSemiBold]
    \definefontsynonym [SerifSemiBoldItalic]    [name:CormorantSemiBoldItalic]
    \definefontsynonym [SerifBold]              [name:CormorantBold]
    \definefontsynonym [SerifBoldItalic]        [name:CormorantBoldItalic]
\stoptypescript

% Do this for each style:
% ...
\starttypescript [serifcormorant] [default] [size]
    \definebodyfont [default] [rmcm]
        % Additional size/alternative combinations are automatically created by
        % ConTeXt.
        %
        % Also according to the manual `definebodyfont` automatically creates macros
        % for each argument, i.e. the `\lt` macro and the `\li` macro and so on are all
        % automatically created by this command.
        [lt=SerifLight sa 1,
         li=SerifLightItalic sa 1,
         tf=Serif sa 1,
         it=SerifItalic sa 1,
         md=SerifMedium sa 1,
         mi=SerifMediumItalic sa 1,
         sb=SerifSemiBold sa 1,
         si=SerifSemiBoldItalic sa 1,
         bf=SerifBold sa 1,
         bi=SerifBoldItalic sa 1,
        ]

% Here we should probably link the standard style macros to the new variants:
%   \rm -> rmcm
%   \sc -> rmsc
% Somehow...

% Right now there are 60 style-alternatives combinations (6 styles * 10
% alternatives). They are duplicated for each `definebodyfont` and
% `definefontsynonym` groups. Alternatively, instead of 6 styles, we can
% keep one style (roman/serif) and define a massive list of 60 alternatives
% in `\definebodyfont` (SerifLight, GaramondSerifLight, InfantSerifLight,
% ..., Serif, GaramondSerif, InfantSerif, ..., SerifBold,
% GaramondSerifBold, InfantSerifBold, ...), which is about half as much
% text. There are enough two-letter combinations (576>60) but they wouldn't
% make sense as abbreviations. Rather, I'd chose alternatives as [aa, ab,
% ac, ad, ..., ba, bb, bc, bd, ...]. I also think it would be confusing to
% mix true *styles* with *alternatives*.

嗯，这确实很令人沮丧，也不起作用，但无论如何，让我们继续讨论不同的字体大小。

\starttypescript [libertinus]
    \definetypeface[libertinus] [rm] [serif] [libertinus] [default]
    \definetypeface[libertinus] [ss] [sans]  [libertinus] [default]
    \definetypeface[libertinus] [tt] [mono]  [libertinus] [default]
\stoptypescript

% Do this for each style:
% ...
% Keep in mind that unlike the cormorant font, each style does not have every
% possible alternative. For example, "Sans" is lacking all SemiBold variations
% as well as BoldItalic.
\starttypescript [serif] [libertinus] [name]
    \definefontsynonym [Serif]                  [name:LibertinusSerifRegular]

    \definefontsynonym [SerifSemiBold]          [name:LibertinusSerifSemiBold]

    \definefontsynonym [SerifBoldItalic]        [name:LibertinusSerifBoldItalic]
    % And now for the font size variants:
    \definefontsynonym [SerifDisplay]           [name:LibertinusSerifDisplayRegular]
    % ... which happen to be defined only for the regular alternative of the serif style.
\stoptypescript

% Do this for each style. However only the serif style provides the *display*
% sizes, and without any alternatives.
\starttypescript
    % According to the reference manual section 5.8.1, when `\setupbodyfont` and
    % `\switchtobodyfont` are given undefined font sizes, they will extrapolate
    % values from the nearest smaller body font environment. Unfortunately this
    % only applies to relative font environments and not individual fonts. So I
    % have to specify every font size, otherwise the default case is used. Which is
    % impossible.
    %
    % For example, I want:
    %   >=20pt
    % What I have to do:
    %   20pt, 20.001pt, 20.01pt, 20.1pt, 20.101pt, 20.11pt, ..., 20.999pt, ..., 21pt, ..., 22pt, ..., 30pt, ..., 100pt, ..., Infpt
    % What I actually end up doing. Some terminal-foo plus copy-paste:
    %   $ python3 -c 'print("pt, ".join(map(lambda i: str(i/2),range(40,200))) + "pt")'

        %
        % I also don't know what concrete sizes to use for suggestions like "caption"
        % or "display". Less than 9pt, 8pt, 5pt? More than 20pt, 30pt, 40pt?

更令人沮丧的是：这也不起作用。

Answer 1

以下是我为 Cormorant 设计打字稿的方式。这并没有映射所有不同的粗细和样式组合，因为其中很多组合都不太合理。
