Vim + Go + Mac

There's a lot of notes written for getting Vim + Go up and running, but a lot of the notes assume you're already in modern Vim-land.  Here's what I did to get up and going from scratch.

0.  Start off with a totally clean vim configuration.

Save off your current files/setting if they're important to you.

    cd $HOME
    rm -rf .vim .vimrc .viminfo

1.  Install a vim with lua support.

I think the easiest way to do this is to install the latest macvim from Homebrew.  If you're a developer on Mac,  Homebrew is well worth looking into.

    brew install macvim --with-cscope --with-lua --override-system-vim

    brew linkapps macvim

    brew install vim --with-lua --override-system-vim

2.  Install Vundle

There's a couple of Vim package managers.  I don't know enough about Vim package management to recommend one over another, but Vundle seems to be pretty popular.

    git clone https://github.com/VundleVim/Vundle.vim ~/.vim/bundle/Vundle.vim

Here's the minimal .vimrc needed to get bootstrapped.

    set nocompatible              

    filetype off                  

    set rtp+=~/.vim/bundle/Vundle.vim

    call vundle#begin()

    Plugin 'VundleVim/Vundle.vim'

    "Plugin 'Valloric/YouCompleteMe'    reserve for step 3 below

    "Plugin 'fatih/vim-go'              <------- font="" nbsp="">reserve for step 4 below

    call vundle#end()            

    filetype plugin indent on    

Restart vim and install the plugins with the command

    :PluginInstall

3. Install YouCompleteMe

This require you install XCode from Apple.  Start off by installing cmake.

    brew install cmake

Install YouCompleteMe and pull in submodules.

    cd ~/.vim/bundle

    git clone git@github.com:Valloric/YouCompleteMe.git

    cd ~/.vim/bundle/YouCompleteMe

    git submodule update --init --recursive

Build YouCompleteMe

    cd ~/.vim/bundle/YouCompleteMe

    ./install.py --gocode-completer

Make sure ~/.vimrc has the line

Plugin 'Valloric/YouCompleteMe'

Restart vim and install the plugin as we did above

    :PluginInstall

4. Install Vim-Go

Download the latest release from https://github.com/fatih/vim-go/releases and untar it.

    cd /tmp

    curl -s https://codeload.github.com/fatih/vim-go/tar.gz/v1.8 | tar xf -

And move all the directories into .vim.  It seems there should be and easier way to do this... ping me if you know what it is!

    (cd /tmp/vim-go-1.8; tar cf - autoload compiler doc \

       ftdetect ftplugin gosnippets indent plugin scripts syntax t templates) |

      (cd ~/.vim; tar xf -)

Then add to .vimrc

    Plugin 'fatih/vim-go'

Restart vim and run

    :PluginInstall
