Go language Learning

Installation of Ubuntu 14.04 GO Language compilation Environment 1. Using Ubuntu's library installation

sudo apt-get install golang

But there are a few bad places to install with Ubuntu libraries:

• The Golang version is determined by the Ubuntu library, ubuntu14.04 currently offers Golang 1.2.1
• The environment settings for the Golang language are already set by default, such as Goroot set to/usr/local/bin,gopath, etc.

It is recommended that you do not use Ubuntu libraries to install Golang environments

2. Install with Golang official documentation

Installation instructions for the Golang community Https://golang.org/doc/install

2.1 Uninstalling the ubuntu14.04 library installation Go

• Uninstalling Golang-go

  sudo apt-get  remove golang-go

• Uninstalling Golang-go and its dependencies

  sudo apt-get remove --auto-remove golang-go

• Uninstall Golang-go and delete its local and configuration files

  sudo apt-get purge golang-go

• Uninstall Golang-go and its dependencies and delete its local and profile files

  sudo apt-get purge --auto-remove golang-go

2.2 Installing with a compiled file

wget https://storage.googleapis.com/golang/go1.6.2.linux-amd64.tar.gztar -C /usr/local -zxf go1.6.2.linux-amd64.tar.gz

Set environment variables, modify the Etc/profile file so that the default search go location

export PATH=$PATH:/usr/local/go/bin

If go is installed in another location, add other locations to the path path

2.3 Test Go Installation

Set the work environment for go, modify the $home/.profile file

export GOPATH=$HOME/gowork

Test Hello-world

mkdir $HOME/gowork/src/hellocd $HOME/gowork/src/hello && touch hello.go

Enter the following code into HELLO.GO

package mainimport "fmt"func main() {    fmt.Printf("hello, world\n")}

Compiling and testing

go install hello$GOPATH/bin/hello

3. Vim Go Language Authoring Environment Configuration 3.1 vim go language syntax highlighting

1. Because the Neocomplete plug-in requires vim7.4 and above, and requires vim to support Lua, the Ubuntu 14.04 Library-installed Vim does not support LUA, so it needs to be uninstalled and installed from the source code. Reference http://winter233.com/Using-Vim-with-Neocomplete/

   Uninstall the original Vim, if the original is not gvim, then the command removes Gvimsudo apt-get remove vim vim-runtime gvim//install vim dependent packages and tools, if you do not need the support of the desktop Environment (GVIM), Delete the gnome\gnomeui\libgtk\libatk\libbonoboui\libcairo\libx11\libxpm\libxt in the command, and if you use Git instead of Hg, delete the Mercurialsudo Apt-get Install Libncurses5-dev libgnome2-dev libgnomeui-dev libgtk2.0-dev libatk1.0-dev Libbonoboui2-dev Libcairo2-dev libx11-dev libxpm-dev libxt-dev python-dev ruby-dev mercurial//install luasudo apt-get Install liblua5.2-d EV lua5.2//compile Vim74 from source, if there is no desktop environment, you can delete the <--enable-gui=gtk2>wget ftp://ftp.vim.org/pub/vim/unix/ Vim-7.4.tar.bz2tar xvf vim-7.4.tar.bz2cd vim74./configure--with-features=huge--enable-multibyte--enable -rubyinterp--enable-pythoninterp--with-python-config-dir=/usr/lib/python2.7/config--enable-perl Interp--enable-luainterp--enable-gui=gtk2--enable-cscope--prefix=/usr//set vim74 rumtimedir, and Finis H installmake vimruntimedir=/usr/share/vim/vim74sudo make Install//check Installation by typing vim--version in shell Or:echo have ("Lua") in Vim. 

3. Install Vundle, used to manage vim plugins, vundle on GitHub, Https://github.com/VundleVim/Vundle.vim

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

   Configure the. vimrc file in the $home directory and paste it from the link address (slightly)

5. Install Vim-go, Vim's Go language plugin, https://github.com/fatih/vim-go modify the. vimrc file, add the following:

   Plugin ‘fatih/vim-go‘

7. Vim-go to fully work, you also need some necessary tools (such as Gocode, Godef, Goimport etc), which can be installed via Vim's :GoInstallBinaries command, if previously installed, can be :GoUpdateBinaries updated, This will allow tools such as Gocode to be installed in the $gopath/bin directory.

9. Install Neocomplete.vim, Https://github.com/Shougo/neocomplete.vim This is the vim-go recommended real-time auto-complete plug-in

   Plugin ‘Shougo/neocomplete.vim‘

10. Install Ctags + gotags + tagbar, where Ctags compatible gotags is used because Ctags does not support go.

    Install Ctagswget http://prdownloads.sourceforge.net/ctags/ctags-5.8.tar.gztar-zxf CTAGS-5.8.TAR.GZCD ctags & &./configure && make && make install//install gotags, see Gotags githubgo get-u github.com/jstemmer/ gotags//add config to. vimrc for tagbarlet g:tagbar_type_go = {\ ' ctagstype ': ' Go ', \ ' kinds ': [\ ' P :p ackage ', \ ' i:imports:1 ', \ ' c:constants ', \ ' v:variables ', \ ' t:types ', \ ' N:interfa    Ces ', \ ' w:fields ', \ ' e:embedded ', \ ' m:methods ', \ ' r:constructor ', \ ' f:functions ' \], \ ' SRO ': '.

12. After the vim is configured, the terminal needs to be re-logged in order to take effect.
