获取Emacs忽略Sweave文档中的\Sexpr {}命令的内容，以防止错误的基于$的语法突出显示 [英] Get Emacs to ignore contents of \Sexpr{} command in Sweave document to prevent incorrect $-based syntax highlighting

问题描述

在LaTeX中编辑Sweave文档（使用Noweb模式）时，Emacs知道忽略<< >> =块中的代码。但是，对于插页式\Sexpr {}块，情况并非如此。由于列的引用通过'$'和LaTeX使用$来排除方程式，这些\Sexpr {}块通常会打破语法突出显示，如下所示：

我有一个非常初步的了解elisp& Emacs语法突出显示，但我希望可能添加一些.emacs将禁用\Sexpr {}中的任何解析/ $检测。

解决方案

我以为ESS的emacs有正确的语法突出显示Sweave？

<无论如何，最简单的修复只是不使用 $ 运算符，而是 [[例如：

  foo $ p.value 
 foo [['p.value']] 
  

应该提供相同的结果。我认为 foo $ p.value 只是 foo [[p.value，exact = FALSE]]的缩写]

When editing an Sweave document in LaTeX (using the Noweb mode), Emacs knows to "ignore" code that is in <<>>= blocks. However, for interstitial \Sexpr{} blocks, this isn't the case. Given that R references by columns via '$' and LaTeX uses $ to set-off equations, these \Sexpr{} blocks often break the syntax highlighting, like so:

I have a very rudimentary understanding the elisp & Emacs syntax highlighting, but my hope is that it might be possible to add something to .emacs that will disable any parsing/$ detection within \Sexpr{}'s.

解决方案

I thought emacs with ESS has correct syntax highlighting for Sweave?

Anyway, the easiest "fix" is to just not use the $ operator but [[ instead. For example:

foo$p.value
foo[['p.value']]

Should give the same result. I think foo$p.value is just short for foo[["p.value",exact=FALSE]]
