Emacs golang 配置

在配置前需要下载用到的包：

<ol><li>godoc</li><li>godef</li><li>gocode</li><li>oracle</li></ol>

在下载包之前需要设置好环境变量：

<pre><span style="color:#000000;"># Golang export GOROOT</span>=$HOME/<span style="color:#000000;">go export GOPATH</span>=$HOME/development/<span style="color:#000000;">go export PATH</span>=$PATH:$GOROOT/<span style="color:#000000;">bin export PATH</span>=$PATH:$GOPATH/bin</pre>

 

如果网络良好的话使用这种方法：
godoc：

<pre>go get golang.org/x/tools/cmd/godoc</pre>

这样会将godoc二进制文件安装到$GOROOT/bin目录里。

godef：

<pre>go get github.com/rogpeppe/godef </pre>

这样会将godef二进制文件安装到$GOPATH/bin目录里。

gocode 自动完成：

<pre>go get -u github.com/nsf/gocode</pre>

这样会将gocode二进制文件安装到$GOPATH/bin目录里。

go oracle

<pre>go get golang.org/x/tools/cmd/oracle</pre>

oracle二进制文件将出现在$GOPATH/bin目录里，将它移动到$GOROOT/bin目录里。

下面是emacs的golang配置：

另一种方法：
注意：从github克隆的golang.org应该放在src目录里！

<pre>~/development/go/src ᐅ git clone https:<span style="color:#008000;">//</span><span style="color:#008000;">github.com/golang/tools golang.org/x/tools</span> 正克隆到 <span style="color:#800000;">'</span><span style="color:#800000;">golang.org/x/tools</span><span style="color:#800000;">'</span><span style="color:#000000;">... remote: Counting objects: </span><span style="color:#800080;">15398</span>, <span style="color:#0000ff;">done</span><span style="color:#000000;">. 接收对象中: </span><span style="color:#800080;">8</span>% (<span style="color:#800080;">1232</span>/<span style="color:#800080;">15398</span>), <span style="color:#800080;">404.01</span> KiB | <span style="color:#800080;">69.00</span> KiB/s </pre>

编译godoc：

<pre>go build golang.org/x/tools/cmd/godoc</pre>

注意：编译出的godoc二进制文件应该放在 ~/development/go/bin目录里!

安装golang教程（这个是英文版的）：

<pre>git clone https:<span style="color:#008000;">//</span><span style="color:#008000;">github.com/golang/tour</span></pre>

<pre>go build golang.org/x/tour/<span style="color:#000000;">gotour golang.org</span>/x/tools/playground/socket/socket.go:<span style="color:#800080;">37</span>:<span style="color:#800080;">2</span>: cannot <span style="color:#0000ff;">find</span> package <span style="color:#800000;">"</span><span style="color:#800000;">golang.org/x/net/websocket</span><span style="color:#800000;">"</span> <span style="color:#0000ff;">in</span><span style="color:#000000;"> any of: </span>/home/z/go/src/golang.org/x/net/<span style="color:#000000;">websocket (from $GOROOT) </span>/home/z/development/go/src/golang.org/x/net/websocket (from $GOPATH)</pre>

怎么办？

<pre>ᐅ git clone https:<span style="color:#008000;">//</span><span style="color:#008000;">github.com/golang/net

<span style="color:#ff0000;">注意：gotour和net这2个目录和tools目录是平级的，它们都在$GOPATH/src/golang.org/x 目录下。</span>
</span>x
├── net
├── tools
└── tour
ᐅ go build golang.org/x/tour/gotour</pre>

安装中文版的教程：

<pre>git clone https:<span style="color:#008000;">//</span><span style="color:#008000;">github.com/Go-zh/tour github.com/Go-zh/tour</span> git clone https:<span style="color:#008000;">//</span><span style="color:#008000;">github.com/Go-zh/tools github.com/Go-zh/tools</span></pre>

注意tour和tools是同级目录。

github.com/Go-zh
├── tools
└── tour

编译中文版教程：

<pre>go build github.com/Go-zh/tour/gotour </pre>

这时会在$GOPATH/src目录中出现一个gotour二进制文件，把它剪切到$GOPATH/bin目录中并重命名为gotour-zh。
在$GOPATH/bin中执行：./gotour-zh 即可开启浏览器。

安装godef：

<pre>git clone https:<span style="color:#008000;">//</span><span style="color:#008000;">github.com/rogpeppe/godef github.com/rogpeppe/godef</span></pre>

<pre>go build github.com/rogpeppe/godef

github.com/rogpeppe/godef/acme.go:11:2: cannot find package "9fans.net/go/acme" in any of:
    /home/z/go/src/9fans.net/go/acme (from $GOROOT)
    /home/z/development/go/src/9fans.net/go/acme (from $GOPATH)</pre>

解决方法：

<pre>git clone https:<span style="color:#008000;">//</span><span style="color:#008000;">github.com/9fans/go 9fans.net/go </span></pre>

然后再编译安装godef：

<pre>go build github.com/rogpeppe/godef</pre>
