在 csquotes 中自定义正式块引用的样式？

Question

好吧，显然我想要的是一个尚未实现的功能。我想我设法解决了这个问题：

测试1.png

... MWE 如下，它需要定义和使用新的用户命令，\DeclareQuoteBlockStyle以及\setquoteblockstyle。但是，可能需要进行一些讨论。

所有这些与内部和外部引用有关的事情都是仅有的\enquote{...}如果您在例如内部使用，则可能\hyphentextcquote；我认为通过\MakeOuterQuote/定义字符也是可行的\MakeAutoQuote- 但似乎不可行。
当你创建样式时\DeclareQuoteStyle，默认情况下不是“应用”在任何地方 - 除非你碰巧用与当前选择的语言相同的名称来命名它。
为了“应用”/“激活”这种引用样式，您不能使用\ExecuteQuoteOptions或\setkeys，因为它们仅在序言中运行；实际上有一个命令可以做到这一点，它是\setquotestyle
使用csquotes'时\DeclareQuoteAlias[variant]{style}{alias}，请注意可以使用alias 仅有的在\setquotestyle{alias}；你可以不是使用（浪费alias了\hyphentextcquote{alias}...这么多时间）。\hyphentextcquote诸如此类多种语言命令，它们的第一个参数应该是实际的语言（如所示babel）。如果恰巧为\hyphentextcquoteetc. 选择的语言也有一个同名的引号样式别名，那么将应用该引号样式。
当你拨打\setquotestyle[italic]{english}（来自\DeclareQuoteStyle[italic]{english}...）电话时，你csquotes被迫出口“多语言模式”；然后中的语言设置就\hyphentextcquote{language}...无关紧要了；中的引用样式\setquotestyle优先。要返回多语言模式，请使用带星号的\setquotestyle*（无参数）。

在寻找块引用样式的自定义时遇到了一些复杂情况；我尝试了\unravel{}- \hyphentextcquote，结果大约需要 14000 步，而且\mkblockquote（鉴于 OP，这显然有影响），甚至没有显示！然而，显示的是，这是\csq@bquote@iii调用它的唯一命令。从它的定义，很显然，除了重新定义之外，没有其他方法可以编辑块引用样式\mkblockquote。

这就是新命令的作用：

\DeclareQuoteBlockStyle与相同，但它有一个额外的第一个可选参数，我们可以在其中为指定一个“样式”\DeclareQuoteStyle的定义；这将以从名称派生的名称保存（因此它应该能够处理多种样式）；并且\mkblockquote[variant]{style}
\setquoteblockstyle与相同\setquotestyle，但它还会根据来设置已保存的“块样式”定义，以[variant]{style}使其\mkblockquote处于活动状态；\setquoteblockstyle*还会恢复\mkblockquote到其原始定义。

请注意，一旦\setquote(block)style正确设置了引号样式，该样式也将通过应用于区块引号\openautoquote（如果存在于中）\mkblockquote！因此，区块引号中的任何额外格式\mkblockquote都将添加到添加通过设置样式\openautoquote；这就是我\bfseries在那里使用的原因，这样就可以在 MWE 上看到涵盖了什么。

好吧，希望我没有误解手册，而且我没有白白编写这些代码。:)无论如何，这里 -csquotes_test.tex @gist.github.com- 是先前的测试文件，带有一些注释；最终的 MWE 是：
