How to use a snipmate variable in an expression

Question

How can I use a snipmate variable in an expression?

snippet foo
    ${1:4} + 2 = `$1+2`

With the default value of 4 the above snippet produces:

4 + 2 = 2

Thanks.

which plugin do you use for snipmate ? – frank.lin Aug 21 '14 at 08:21 — frank.lin, Aug 21 '14 at 08:21

At least in the original snipMate plugin, expressions are evaluated first, then tab stops. This allows you to define things like ${1:`v:version`}, but it makes your use case impossible to achieve.

Have a look at UltiSnips; it is modern and powerful, and might allow this. There are more alternatives, see this list on the Vim Tips Wiki.
