Tab fields after arbitrary elisp

[Ross Donaldson]

Hullo all --

First off: yasnippet has saved me so much time. Thanks to all the creators! Great stuff.

Question: I want to insert text based on evaluating a conditional expression, and then I want a tab field. I imagine this working like so (example imagines YAML mode, but I doubt that matters):

field_one: ${1:default}
field_two: ${2:default}
`(if(my-predicate-fn)
   "field_three_a: "
   "field_three_b: ")`$3
$0

But this doesn't work at all -- field $3 is skipped every time. What don't I grok about this? 

Thanks!

This seems to be the same question as your previous message (if it's not
please tell me).

Anyway, your example looks fine. I don't know what `my-predicate-fn`
does, but I've just tested something similar which works fine:

${1:foo}
`(if (zerop (random 2)) "bar: " "baz: ")`$2
$0

Can you open an issue in https://github.com/capitaomorte/yasnippet/issues ?

Be sure to read the README.md for guidelines when reporting issues
though (I need to be able to reproduce it just like it happened to you.)
