在朱莉娅的原始文字字符串

问题描述

在Python中，可以写入 ra\\\
b，以防止 \\\
被解释为转义序列的换行符。

In Python one can write r"a\nb" in order to prevent the \n from being interpreted as an escape sequence for newline.

在Julia有类似的东西吗？而如果像$ variable这样的字符串插入怎么办？有没有办法阻止它？

Is there something similar in Julia? And what about string interpolation like "$variable", is there a way to prevent it?

我知道一个可以在Julia中写下a\\
b和\ $ variable喜欢写很多LaTeX字符串，而不必关心每个反斜杠 \ 和美元 $ 字符的正确转义。

I know one can simply write "a\\nb" and "\$variable" in Julia, but I would like to write a lot of LaTeX strings without having to care to proper escape every backslash \ and dollar $ characters...

（在Julia， r...创建一个正则表达式。）

(In Julia, r"..." creates a regular expression.)

推荐答案

好的，我刚刚发现，由于可以轻松创建，我将要求的是：

Ok, I just found out that since one can easily create non-standard string literals in Julia, a pass-through one will do what I was asking for:

macro R_str(s)
    s
end

>>> R"$a\n$b"
"\$a\\n\$b"
>>> print(R"$a\n$b")
$a\n$b

我还发现定义了一个类型，可以通过 L....没有转义反斜杠或美元符号»，另外有益于在IJulia提出的方程式。

I also discovered that PyPlot.jl defines a «LaTeXString type which can be constructed via L"...." without escaping backslashes or dollar signs», with the additional benefit of rendered equations in IJulia.

最后一个问题是：不值得拥有一个原始的在朱莉娅基地的字符串字面量？

A last question remains: is not worth it to have a raw string literal in Julia base?
