You probably want to be using https://github.com/fatih/vim-go instead
This plugin adds godef support to vim.
The godef tool from Roger Peppe parses Go code and returns the location of
the definition of a symbol. It can be installed with
go get -v github.com/rogpeppe/godef
go install -v github.com/rogpeppe/godef
To install the vim-godef plugin, clone this vim-godef repository and (from it) copy plugin/godef.vim to ~/.vim/plugin .
Or, if you're using pathogen, on Linux:
git clone https://github.com/dgryski/vim-godef ~/.vim/bundle/vim-godef
or on Windows:
git clone https://github.com/dgryski/vim-godef %USERPROFILE%\vimfiles\bundle\vim-godef
This modules overrides the gd (go to local definition) command to open a new
window at the definition of the symbol under the cursor. Setting
g:godef_split=0
(that is, entering the command let g:godef_split=0 or inserting it into your ~/.vimrc)
will reuse the current window, and
g:godef_split=2
will open the definition in a new tab, and
g:godef_split=3
will use a vertical split instead of the default horizontal split.
If you want jumps to the same file to move your current cursor instead of splitting, use
g:godef_same_file_in_same_window=1
This also adds a :Godef which will work for global types, methods,
constants, and variables in the current package.
