在 ConTeXt (MkIV) 中使用 typescript 激活连字

在 ConTeXt (MkIV) 中使用 typescript 激活连字

我有以下示例，我尝试为字体启用连字咖啡情结

\definefontfeature[yanone-default][mode=node, kern=yes, liga=yes, dlig=yes]

\starttypescript [sans] [yanone]    
    \setups[font:fallback:sans]
    \definefontsynonym [Sans] [Yanone-Regular] [features=default]
\stoptypescript

\starttypescript [sans] [yanone]
    \definefontsynonym [Yanone-Regular][name:yanonekaffeesatzregular][features=yanone-default]
\stoptypescript

\starttypescript [yanone]
    \definetypeface [yanone][ss][sans][yanone][default]
\stoptypescript
%--------------------------------------------------------------------------------

\usetypescript  [sans] [yanone]
\setupbodyfont  [yanone,36pt]

\starttext

fi fl ff ffi ffl

\stoptext

排版成功，文档中用到了字体，但缺少连字符。我是不是漏掉了打字稿中的重要内容，还是

liga=yes

足够的？

这标本字体恰好显示了代码中上面显示的五个连字符。

使用的 ConTeXt 版本是：

以下是修复缺失连字符和更完整的打字稿的代码：

\startbuffer [yanone-feature]
lookup fligatures {
  lookupflag 0;
    sub \f \i    by \fi;
    sub \f \l    by \fl;
    sub \f \l    by \fl;
    sub \f \f \i by \ffi;
    sub \f \f \l by \ffl;

} fligatures;

feature liga {
  script DFLT;
    language dflt;
      lookup fligatures;
  script latn;
      language dflt;
      lookup fligatures;
} liga;
\stopbuffer
\savebuffer [yanone-feature]

代码\startbuffer只是将内容写入文件。您还可以获取缓冲区的内容并将其保存在外部文件中。文件名传递给featurefile。这可以纠正缺失的连字符。

其余部分是正常的打字稿，考虑到 Yanone-Kaffeesatz 有三种粗细。我指定 latin modern 作为 math 和 monotype 的后备。您可以/应该更改它并使用您想要与 Yanone-Kaffeesatz 结合的字体。

当你不使用\s!快捷键时，你也可以删除\protect和\unprotect。它看起来像这样：
