Yasnippet including backslash

Question

I would like to use Yasnippet to insert the template for a latex inline equation: \( \)

The snippet is defined:

 # -*- Mode: snippet -*- # name: inline equation # key: ineq # -- \( \)

But Yasnippet inserts only the parentheses ( ) without the backslashes. Any suggestions?

The backslash is used in regular expressions to escape individual characters:

For the most part, \ followed by any character matches only that character.

So \( gives you ( in your output. To get the backslash in the output, escape it:

\\( \\)

joaotavora.github.io/yasnippet/snippet-development.html#sec-3 would be a better link, this isn't about regular expressions. — npostavs
