How to make optional arguments

Asked by bob saget on 2011-09-19

I want to make a self documenting function snippet with any optional number of arguments, so for example

function moo(a, b) {

}

would get
/**
* TODO
* @method moo
* param {} a
* param {} b
**/

With a, b and any other arguments being completely optional (including no arguments). Something like infinitely optional arguments would be great

* {?@param {} $n}
function ${1:function_name}({$n separator=", "}) {

Or something like that,. Is that possible?

You cannot define tabstops dynamically, no. But what you want to achieve is still possible. Have you tried?

set ft=python
def<tab>

now overwrite arg1 with >a, b, c, d<. Is this what you want to do? If so, check out how it is done in the shipped python snippets.
