#标签排序，0-9A-Z
#标签支持正则表达式，例如一个标签
#AAA/BBB/CCC
很长，只想显示CCC，可以用正则
/^#(?:.+\/)*(.+)/
，这个正则不仅用于#标签的原始标签->正则匹配的标签的映射，还作为嵌套标签的验证，属于高级用法，详见下面
getTagMatch
函数
如果你不会正则表达式，但有高级需求，请在讨论中提问
static getTagMatch(tag: string) {
// 监测是否为正则表达式
const rawString = Zotero.Prefs.get(`${config.addonRef}.textTagsColumn.match`) as string
const res = rawString.match(/\/(.+)\/(\w*)/)
let regex: RegExp;
// 是正则表达式
if (res) {
regex = new RegExp(res[1], res[2])
// 不以xxx开头
else if (rawString.startsWith("~~")) {
regex = new RegExp(`^([^${rawString.slice(2)}].+)`)
// 以xxx开头
else {
regex = new RegExp(`^${rawString}(.+)`)
const matched = tag.match(regex)
return (matched && matched.slice(1).join("")) || ""
