Youcompleteme: Move to maintained version of Gocode

[flowchartsman]

As mentioned in https://github.com/fatih/vim-go/issues/1932, vim-go has moved to a new version of gocode because of 1.10 and 1.11 incompatibilities, and YCM should too.

PR https://github.com/Valloric/ycmd/pull/1098 takes care of this.

[flowchartsman]

I'll leave this up until the PR lands, then, to track and keep resubmissions down.

[flowchartsman]

This has been merged into ycmd/master, closing PR

[flowchartsman]

I was wrong. While this has landed in ycmd, YouCompleteMe is still broken.

[flowchartsman]

@Valloric could you re-open?

[micbou]

We need to update the ycmd submodule.

[flowchartsman]

Thanks, sorry for the churn.

What are the possible impacts of this before it is "fixed"?

I am running go 1.11, using MacVim as suggested, followed all the docs, etc and the auto-tiggers for go still don't seem to work.

A comment here mentions that that YouCompleteMe is "broken" due to this. <CTRL-Space> seems to work as does <C-x><C-o>. However, I should be able to type something like fmt. and start to see completions. That isn't happening.

Just go into YouCompleteMe/third_party/ycmd and pull the latest master if you need this fixed. With go 1.11 YCM is completely broken with an updated ycmd submodule. The <C-x><C-o> (or better said, omnifunc) is not something that YCM uses.

[davidnewman]

I'm certainly doing something wrong, or misunderstanding what's being said. Here's what I am doing:

1. I use vundle, so I went and commented out the line adding the YouCompleteMe plugin from my .vimrc file. I then issues the :PluginClean command which deleted YCM from my system.
2. I then uncommented the plugin line and issued :PluginInstall.
3. I went to ~/.vim/bundle/YouCompleteMe/third_party/ycmd and did git checkout master && git pull
4. I then went to ~/.vim/bundle/YouCompleteMe and issued ./install.py --go-completer and I get the following error:

can't load package: package github.com/mdempsky/gocode: no Go files in /Users/dnewman/.vim/bundle/YouCompleteMe/third_party/ycmd/third_party/go/src/github.com/mdempsky/gocode

Any idea as to what is up here?

[bstaletic]

Go back to YouCompleteMe/third_party/ycmd and do git submodule update --init --recursive. Then rebuild.

[davidnewman]

Thanks! This is working great now. Just to keep it easy, here are the steps.

Starting assumption:

1. All you've done is install YouCompleteMe and followed the instructions for install.py --go-completer

Outcome:

1. You do not see YouCompleteMe working for autocompletion of go files.

Fix:

1. Change ycmd to be on master:

cd ~/.vim/bundle/YouCompleteMe/third_party/ycmd
git checkout master
git submodule update --init --recursive

1. Repeat building the completers using the install.py script:

cd ~/.vim/bundle/YouCompleteMe
./install.py --clang-completer --go-completer

NOTE: Your invocation of ./install.py may differ if you are enabling other completers.

Outcome:

You should be able to open a Go file and see autocomplete working.

Another note: Vundle's :PluginUpdate, if I remember correctly, will try to run git submodule update --init --recursive in YouCompleteMe directory and, since ycmd is a YouCompleteMe submodule, it will be reverted to a broken commit.
