go-graphviz

产生Graphviz 文件
用 Golang 产生Graphviz 文件的封装方法如下
https://github.com/awalterschulze/gographviz
我们使用它的范例代码如下：

package main

import (
“fmt”
“github.com/awalterschulze/gographviz”
)

func main() {
graphAst, _ := gographviz.Parse([]byte(digraph G{}))
graph := gographviz.NewGraph()
gographviz.Analyse(graphAst, graph)
graph.AddNode(“G”, “a”, nil)
graph.AddNode(“G”, “b”, nil)
graph.AddEdge(“a”, “b”, true, nil)
fmt.Println(graph.String())
}
使用 dot 生成 png 的命令行如下：

dot 11.gv -T png -o 11.png

完整的 Go 代码如下：

package main

import (
“bytes”
“fmt”
“github.com/awalterschulze/gographviz”
“io/ioutil”
“os/exec”
)

func main() {
graphAst, _ := gographviz.Parse([]byte(digraph G{}))
graph := gographviz.NewGraph()
gographviz.Analyse(graphAst, graph)
graph.AddNode(“G”, “a”, nil)
graph.AddNode(“G”, “b”, nil)
graph.AddEdge(“a”, “b”, true, nil)
fmt.Println(graph.String())

// 输出文件

ioutil.WriteFile("11.gv", []byte(graph.String()), 0666)



// 产生图片

system("dot 11.gv -T png -o 12.png") }

//调用系统指令的方法，参数s 就是调用的shell命令
func system(s string) {
cmd := exec.Command(/bin/sh, -c, s) //调用Command函数
var out bytes.Buffer //缓冲字节

cmd.Stdout = &out //标准输出

err := cmd.Run()  //运行指令 ，做判断

if err != nil {

    fmt.Println(err)

}

fmt.Printf("%s", out.String()) //输出执行结果 }

go-callvis 是github上一个开源项目，可以用来查看golang代码调用关系。
安装go-callvis
go get -u github.com/TrueFurby/go-callvis
cd $GOPATH/src/github.com/TrueFurby/go-callvis && make

查看github.com/github/orchestrator/go/http 这个package下面的调用关系：

$ go-callvis -focus github.com/github/orchestrator/go/http github.com/github/orchestrator/go/cmd/orchestrator
