SnipMate/UltiSnips integration

[kballenegger]

A killer feature would be for YCM to include SnipMate snippets in its suggestions.

I'm making this an issue in case a contributor sees this. I unfortunately do not have the skills required to build this.

[Valloric]

I'm not a fan of this. I use snippets as well (UltiSnips) but I don't think integrating it with a code-completion system would be the best approach.

Thanks for the feedback though!

For what it's worth. I think snippet integration would be nice as well. My snippets no longer complete with YCM, so I may have explore changing the trigger.

[kballenegger]

Ditto, see how Xcode does it. It's really nice, your snippets are offered as autocompletion, it's super neat.

+1 (ultisnips)

"snippets offered as autocompletion" is something I didn't imagine, it could be awesome.

[drasill]

Although, binding <C-j> to ultisnips make it easy to use again.

[Valloric]

I'm slowly changing my mind about this. If we could figure out a way for YCM to talk to UltiSnips/Snipmate in a way that doesn't complicate matters too much, I'd support it.

UltiSnips support will probably come first; I'm not sure about Snipmate because upstream has a note about Snipmate dying and it recommends UltiSnips, so that's not a good sign.

The way clang_complete uses Ultisnips is the best approach. Besides allow you to complete snippets with once you accepted a completion and this completion is a function call, than YCM should provide an "anonymous" snippet with the parameters of the function to be completed. Ex:

I type:

prtf

Than YCM offers me "printf" among others. After I press than , YMC shuld give me this:

printf("format string", parameters);

Where:

"format string" - is the first argument of the snippet
, parameters - is the optional argument

Also, regarding how to complete a snippets or "other completions", I think YMC should do this:

I type:

if

YMC provides me some options. The snippets should be listed on top of the options and marked somehow so user can clearly see what's this about. If user, press , than Ultisnips should be triggered and if the offered snippet has more than one possibility, than YCM should change the completion list to show all snippets available for the chosen snippet.

I'm pretty sure if you contact the developers of Ultisnips they can help you figure out a way to implement that.

[Valloric]

I'll probably talk to the UltiSnips developer at some point, yes.

I like your first feature, where pressing TAB after "ptrf" also inserts the parameter names. But this can be implemented without UltiSnips actually.

The second feature sound good too, but that will not be easy to implement and will require quite a bit of cooperation with the snippets plugin.

[capitalist]

Wow, how often does a maintainer remain open-minded after dismissing an issue.

Loving YCM and now @Valloric too. Respect.

[Townk]

Agree that "parameter" completion can be achieved without Ultisnips. That being said, Ultisnips already provide a python API to do that, and it'll give you the possibility to use powerful snippets features like python interpolation.

[Valloric]

@Townk I didn't know UltiSnips provided such an API. I'll be using it then.
