使用 csv 文件扩展 siunitx 词汇表条目

Question

这是一个更好的方法：

\NewDocumentCommand{\loadglssymbolcsv}{ m }{
 \DTLifdbexists{symdata}{}{\DTLloaddb{symdata}{#1}}%
 \glsnoexpandfields
 % Iterate through the columns and generate a newglossaryentry
 \DTLforeach*{symdata}%
 {%
  \key=key,%
  \symbol=symbol,%
  \units=units,%
  \description=description%
 }{%
  \edef\defnewentry{\noexpand\newglossaryentry{sym-\key}%
    {name={\expandonce\symbol},
     description={\expandonce\description},
     unit={\expandonce\units},type=symbolslist}}%
  \defnewentry
 }%
}

它确保占位符命令只扩展一次。

其他一些小修正：

\makeglossaries应该放在条目定义之前。
注意行尾字符。它们可能会导致不必要的空格。您需要将它们注释掉。

关于需要创建.glsdefs用于 atom 自动完成的文件，你现在可以（从glossaries-extra版本 1.34，2018-07-29）使用包选项docdef=atom，其行为类似docdef=restricted，但也会在.glsdefs不读取文件的情况下创建文件。这将允许前言定义，而无需glossaries.tex在文档中重新加载。
