I have the following utilsnips script that I use for Vim:
snippet - "assignment"
<-
endsnippet
I use it for R to expand a dash to the assignment operator. I would like to make it so that a space is put both before and after the <-
on expansion. However, when I put a space before it in the snippet like <-
, it won't expand on hitting Tab
. How should I modify the script to have spaces around the operator? Desired result: <-
.
You could use r
option to include head and trailing spaces around snippets. r
will treat snippet as a python regular expression and you should define your snippet within quotes when using this flag.
snippet " -" "assignment" r
<-
endsnippet
Note that there is a space before and after <-
in snippet definition.
As a bonus, It's more interesting to define the snippet like the following:
snippet " - " "assignment" rA
<-
endsnippet
A
is autoexpansion. so now you dont need to hit tab
anymore! just type -
and as soon as you type space after -
it will expand to <-
Automatically.
