TexWorks JavaScript 转换为 SI 单位

TexWorks JavaScript 转换为 SI 单位

我尝试为 TexWorks 编辑器编写一个脚本。我希望能够将易于写入的物理单位转换为 SI-Unit latex 包的语法。

例如：

我写的：12,45A

标记它并点击我的快捷方式将其转换为（通过脚本）

\SI{12.45}{\安培}

我设法整理了以下脚本：

// TeXworksScript
// Title: convert SI
// Shortcut: Ctrl+Shift+K
// Description: Converts into SI 
// (...)
// Script-Type: standalone
// Context: TeXDocument



function addOrRemove(prefixA, suffixA, prefixB, suffixB) {
  var txt = TW.target.selection; //ausgewählter text
  //var komplett = txt.match(/\d+\,\d+[a-zA-Z]+/);
  //txt=txt.replace(",",".");
  var zahl = txt.match(/\d*\,?\d*/);
  zahl=zahl.toString().replace(",",".");
  var einheit = txt.match(/[a-zA-Z]+/);
  einheit=einheit.toString().replace("V","\\volt ");
  einheit=einheit.toString().replace("kmh","\\kilo\\meter\\per\\hour ");
  einheit=einheit.toString().replace("W","\\watt ");
  einheit=einheit.toString().replace("A","\\ampere ");
  einheit=einheit.toString().replace("m","\\meter ");
  einheit=einheit.toString().replace("g","\\gram ");
  einheit=einheit.toString().replace("kg","\\kilo\\gram ");
  einheit=einheit.toString().replace("ms","\\meter\\per\\second ");
  einheit=einheit.toString().replace("s","\\second ");
  var wrapped = prefixA + zahl + suffixA + prefixB + einheit + suffixB;
  var len = txt.length;
  var pos = TW.target.selectionStart;
  if (pos >= prefixA.length) {
    TW.target.selectRange(pos - prefixA.length, wrapped.length);
    TW.target.selectRange(pos, len);
  }
  TW.target.insertText(wrapped);
  TW.target.selectRange(pos + prefixA.length + 5 + 2*len, 0);
  return;
};

addOrRemove("\\SI{", "}", "{", "}");

这种方法还算有效。第一个问题是替换。它迭代进行，因此我得到了两次替换。 2公里每小时变成\SI{2}{\千米/小时 }

如果我能解决单个正则表达式部分并使用它们，那将会非常有帮助。

非常感谢您的帮助。

看来，我找到了答案。
