I created the following snippet:

snippet setttwd
    setwd(dirname(rstudioapi::getActiveDocumentContext()$path))

But when I type setttwd and press enter, I get the following piece of code:

Note that $path has disappeared.

Why?

CodePudding user response：

Because $ is used as a special character to denote where the cursor should jump after completing each section of a snippet, in order to insert a literal $ it must be escaped as \$.

Replacing $ by \$ solved the issue

snippet setttwd
    setwd(dirname(rstudioapi::getActiveDocumentContext()\$path))
