\use:c 已定义 — 调用 \glsaddkey 的命令

\GlsAddKey我正在尝试使用预设字段对 中的键创建进行编码\glsaddkey。换句话说，我对 所做的操作bar，我希望能够对任意键执行。

附言：我不明白\glsaddstoragekey，所以我把它留在那里以防有人想评论。

\documentclass{article}
\usepackage{glossaries}
\usepackage{xparse}
\makenoidxglossaries

  \glsaddstoragekey*{foo}% key
  {NA}% default value
  {\glsentryfoo}% command analogous to \glsentrytext

  \glsaddkey*{bar}% key
  {NA}% default value
  {\glsentrybar}% command analogous to \glsentrytext
  {\Glsentrybar}% command analogous to \Glsentrytext
  {\glsbar}% command analogous to \glstext
  {\Glsbar}% command analogous to \Glstext
  {\GLSbar}% command analogous to \GLStext

  \newglossaryentry{x}
  {
    name={X},
    description={next letter ??},
    % description={letter \glsfoo{x}}%,
    bar={Y}
  }

  \newglossaryentry{y}
  {
    name={Y},
    description={next letter \glsbar{y}},
    % description={next letter ??},
    bar={Z}
  }

  \ExplSyntaxOn
  
  \NewDocumentCommand\GlsAddKey{m}
  {
      \glsaddkey*
      {#1}% key
      {NA}% default value
      {\use:c{glsentry#1}}% command analogous to \glsentrytext
      {\use:c{Glsentry#1}}% command analogous to \Glsentrytext
      {\use:c{gls#1}}% command analogous to \glstext
      {\use:c{Gls#1}}% command analogous to \Glstext
      {\use:c{GLS#1}}% command analogous to \GLStext
  }
  
  \ExplSyntaxOff

当你这样做时\glsaddkey*{bar}，glossaries包会执行类似

\newcommand{\glsentrybar}{...}

对于由命令名称组成的每个参数。当然

\newcommand{\use:c{glsentryqux}}

将会以错误消息中显示的方式失败。您需要提供一个已经形成的令牌。一种快速（但不太好）的方法是提前进行必要的扩展。

\NewDocumentCommand\GlsAddKey{m}
  {
   \use:x
    {
     \exp_not:N \glsaddkey*
      {#1}% key
      {NA}% default value
      {\exp_not:c{glsentry#1}}% command analogous to \glsentrytext
      {\exp_not:c{Glsentry#1}}% command analogous to \Glsentrytext
      {\exp_not:c{gls#1}}% command analogous to \glstext
      {\exp_not:c{Gls#1}}% command analogous to \Glstext
      {\exp_not:c{GLS#1}}% command analogous to \GLStext
    }
  }
