This project is an IDE for the Go language based on amix's most excellent Ultimate Vimrc. In addition to the terrific Vim plugins that were included in Ultimate Vimrc, the following packages were added:
- neocomplete: Next generation completion framework
- UltiSnips: The ultimate snippet solution for Vim
- Tagbar: Displays tags in a window, ordered by scope
- CSApprox: Makes gvim-only colorschemes work transparently in terminal vim
- Colour-Sampler-Pack: Top 100(ish) Vim colorschemes
- ScrollColors: Colorsheme Scroller, Chooser, and Browser
The following is a sample screen shot showing:
- Keyword auto-completion feature for some Go code in the center window
- Directory tree listing on the left
- Tags window on the right (similar to a table of contents)
The neocomplete plugin requires a version of Vim with Lua support. To see if your version includes Lua support, check for the "+lua" flag in the vim version information:
vim --version | grep +lua
For Ubuntu, the following versions of Vim include Lua support (choice depends on your graphical environment):
* vim-nox (no GUI support)
* vim-gtk
* vim-gnome
* vim-athena
For CentOS7, this script can be used to compile a version of Vim with Lua support.
The TagBar plugin requires the Exuberant version of Ctags. To check whether your current Ctags is the exuberant version:
ctags --version | grep Exuberant
To install Exuberant Ctags on Ubuntu:
cd ~/Downloads
wget https://sourceforge.net/projects/ctags/files/ctags/5.8/ctags-5.8.tar.gz
tar -xzf ctags-5.8.tar.gz
cd ctags-5.8
./configure
make
sudo make install
To install, run the following commands:
git clone https://github.com/diverdane/vim-go-ide.git ~/.vim_runtime
~/.vim_runtime/install.sh
This will clone the repository, and set up ~/.vimrc to use the new ~/.vim_runtime directory (a backup copy of ~/.vimrc will be created). Next, start up Vim and enter the following to ensure that your Go development environment includes the necessary binaries (and updates) upon which Vim depends:
:GoInstallBinaries
:GoUpdateBinaries
Optionally, create an alias (e.g. in ~/.bashrc or .bash_aliases) for vi:
alias vi=vim
export EDITOR=vim
The following function key mappings were added for convenience. These mappings can be displayed in Vim by pressing <F7>:
<F2> Directory tree window (open/close)
<F3> Line numbering (on/off)
<F4> Go to definition for a Go function, struct, etc.
<F5> Show callers for a Go function
<S-F5> Set scope (top directory) for Go callers search
<F6> Show callstack(s) for a Go function
<F7> Show this function key mapping info
<F8> Tag bar window (open/close)
<F9> Show Go snippets
<F10> Show Go key mappings
<F11> Maximize/minimize window
<F12> Scroll through installed Vim colorschemes
The following Go-specific key mappings were added. All but the last are only effective when editing a Go file. These mappings can be displayed by pressing <F10>:
Sequence Function Description
======== ======== ===========
K doc Show documentation for item under the cursor
gd def Jump to definition/declaration
,r run Runs 'go run'
,b build Runs 'go build', does not create result file
,B make Runs 'go build', creates result file
,t test Runs 'go test'
,c coverage Runs 'go test -coverprofile-temp.out'
,dd def Jump to definition
,ds def-split Jump to definition in a split window
,dv def-vertical Jump to definition in a vertical split window
,dt def-tab Jump to definition in a tab window
,kk doc Show documentation for item under cursor
,kv doc-vertical Show documentation in vertical split window
,kb doc-browser Show documentation in a browser
,im implements Show interfaces that a type implements
,in info Show type info for item under the cursor
,e rename Rename the identifier at cursor (throughout package)
,P GoPlay Share snippet to play.golang.org and open browser
,T NERDTreeFind Display the current file in a directory tree
The following Go-specific snippets are included. These snippets are only in effect while editing Go files, and can be displayed by pressing the <F9> key. To use a snippet, while in insert mode type the sequence shown below followed by a <Tab>, and a snippet of code will be inserted:

By default, the :GoCallers command (which can also be initiated via <F5>) searches for all callers to the current Go function only within the current package. For large, multiple-package projects, it's desirable to expand the search to look for callers outside of the current package. This can be accomplished dynamically either by using the :GoGuruScope command, or by navigating within the directory tree window (see next section) to the desired top directory or bookmark, and selecting <S-F5> (shifted F5 function key).
Note that you don't want to set the search scope too arbitrarily large, since searches across larger scopes will take longer to complete.
The <F2> function key can be used to toggle the directory tree window open/closed. The directory tree window can also be opened for the current file by entering ",T" while editing the file. Here are a few key sequences to help navigate in the directory tree window:
<F2> Turn directory tree window on/off
<S-F5> Set scope (top directory) for Go callers search
<Enter> Open current selection
u Move up to parent directory
C Change directory into current selection
B Toggle bookmark listings on/off
:Bookmark <name> Bookmark the current selection with specified name
:Bookmark Bookmark the current selection using dir/file name
<Double-Click> Expand selected directory or open selected file
:help NERDTree View documentation for NERDTree
The <F8> function key can be used to toggle the Tagbar window open/closed. To view documentation for Tagbar, enter the following while in Vim:
:help TagBar
Documentation for the vim-go plugin can be viewed by entering the following from within Vim:
:help vim-go
The vim-go tutorial can be found here: https://github.com/fatih/vim-go-tutorial
Documentation for the vimrc project can be viewed by entering the following from within Vim:
:help vimrc
Don't like the colorscheme that's included? You can browse through over 100 colorschemes by pressing <F12> and scrolling using the arrow keys. If you find one that you prefer, you can set it as your default colorscheme by adding a 'colorscheme <your-choice>' entry in ~/.vim_runtime/my_configs.vim.
If you'd like to make changes to key mappings, colorschemes, or any behavior, you can add settings to ~/.vim_runtime/my_configs.vim file. You can also install your own plugins by cloning the plugins to the ~/.vim_runtime/sources_non_forked directory (pathogen will automatically detect and install the new plugins.
