Autocomplete with expand arguments in snippet

[kvaneesh]

I am writing this to check whether we support argument expansion while autocomplete ?. Something similar to http://emacs.stackexchange.com/questions/9526/extending-autocomplete-for-go-to-insert-function-arguments

Imho, such feature requires to sent full set of completion model, just like tokens to client side.

So, if I can ask for some additional requirements for such interfaces changes:
Please implement such kind of output interfaces changes in json format, while it's needed to implement good enough plugin implementation in vim-rtags to compete with ycm's c++ semantic completion implementation.

As reference implementation of completion string mapping in format like json model, you can use such python bindings. Their completion string mappings have rest of detail which are enough for the most full completion implementation on the client side.

This looks interesting. If we get an emacs implementation then we could possible make the language server available to other editors too.

Incidentally. This is now implemented. There might be bugs but you can now
do something like this:

rc --code-complete-at /Users/abakken/dev/rtags/src/rdm.cpp:50:1:
--synchronous-completions --json

Note that I suspect there's too much info there for it to be performant. I
think the ideal solution maybe filters out something on the server side.

Is the emacs part of this done ? I guess company mode integration will also need an update to show the details ?

[Andersbakken]

Not really. I don't entirely know what one would need to do to implement it
at this point.

https://github.com/company-mode/company-mode/blob/master/company-gtags.el that indicate that we can insert argument template if the company backend support it when building completions. I am not expert in elisp to code that. But i noticed that even rc --code-complete-at --elisp returns the argument details. So we may be able to skip the all the json part and just get the arguments in completion with simple hack ?

[Andersbakken]

Hm. You know what. We already do this apparently. I think Philippe Vaucher
added this in his initial company contribution. My bad.

I think we can close this.
