List of options

I am not sure what you want to achieve. You can define the same trigger more than once and then select on expansion which one you want.

Here is a simple (though impractical) example.

I want the snippet to trigger when I type CREATE.
Then I want to provide the user (using OMNI completion or something similar) a list of items to create.

CREATE<tab>

The popup list should provide:
TABLE
PROCEDURE
FUNCTION

In many of the SQL completions I plan, there are always a static list of options that I would like to make available to the user as they move through the different tabstops. This would make the completions more valuable.

Here would be a more real life example:

snippet DECLARE ${1:name} {2:parameters, one of the following:
[ NO SCROLL
  | DYNAMIC SCROLL
  | SCROLL
  | INSENSITIVE
  | SENSITIVE
]
}
CURSOR FOR {3:statement}
{4:

So the 2nd parameter would give the user a list of those options to choose from.

I am sorry that ultisnips does not offer what you need. I can offer something similar though: Have a look at my screencast about python interpolation in UltiSnips [1], I code a complete function that I use for this very use case you have here. Maybe that is valuable to you?

Yes, that was the video I was remembering, but could not remember where.

So, the base case worked ($1, one set of completions).

Next I tried to get somewhat fancier and things start breaking.

global !p
def complete(t, opts):
    if t:
        opts = [ m[len(t):] for m in opts if m.startswith(t) ]
    if len(opts) == 1:
        return opts[0]
    return '(' + '|'.join(opts) + ')'
endglobal

snippet cursor "cursor" !i
    DECLARE $1 $2`!p snip.rv=complete(t[2], [ 'NO SCROLL', 'DYNAMIC SCROLL',
    'SCROLL', 'INSENSITIVE', 'SENSITIVE' ])` CURSOR FOR
    $3
    $4`!p snip.rv=complete(t[4], ['FOR READ ONLY', 'FOR UPDATE', 'FOR UPDATE BY ', 'FOR UPDATE OF $5' ])`
endsnippet

What I want to do is embed another tabstop ($5 in this case) so that if they choose the "FOR UPDATE OF" option, they get another tabstop to <C-J> to.

Is this possible?

Thanks,
David

No, programmatically generating new placeholders on the fly is not possible right now. I am sorry.
