* 测试安装环境 File => New... => Go1 Command Project => Name: Greedy => OK
对于默认的输出helloworld的项目 按 command + R, 编译并运行
* 启动godoc api文档服务 godoc -http=:6060 & 用浏览器打开 http://localhost:6060/ 一些参考手册链接打不开 go get golang.org/x/blog package golang.org/x/blog: unrecognized import path "golang.org/x/blog" (https fetch: Get https://golang.org/x/blog?go-get=1: dial tcp 216.239.37.1:443: i/o timeout) 博客下载超时,需要安装gopm go get -u github.com/gpmgo/gopm ls $GOBIN # go godoc gofmt gopm # gopm安装成功
用gopm安装 golang.org/x/blog if [ ! -d $GOPATH/bin ]; then mkdir $GOPATH/bin; fi gopm bin -d $GOPATH/bin golang.org/x/blog output: [GOPM] 07-29 11:50:20 [ WARN] Getting imports: no buildable Go source files in /var/folders/60/qw4hdqc50m32mwxr054b9j200000gn/T/359841253/src/golang.org/x/tools [GOPM] 07-29 11:50:20 [ WARN] Getting imports: no buildable Go source files in /Users/Mch/Code/golang/.vendor/src/golang.org/x/tools [GOPM] 07-29 11:50:21 [FATAL] Previous steps weren't successful or the project does not contain main package 出错了 cd $GOPATH/src/github.com/github.com/gpmgo/gopm go build . go install gopm install golang.org/x/blog # 这个错误❌ [GOPM] 07-29 12:00:54 [FATAL] fail to list imports: fail to get imports(/Users/Mch/Code/golang): import "/Users/Mch/Code/golang": cannot import absolute path rm -f $GOBIN/gopm 再将$GOPATH/bin添加到PATH环境变量 which gopm # /Users/Mch/Code/golang/bin/gopm # 把gopm安装到$GOPATH/bin, 再试 gopm get -g golang.org/x/blog # go get golang.org/x/blog 用gopm替换go 重启godoc服务 lsof -i:6060 | awk '{if(NR>1) {print $2}}' | xargs kill -SIGTERM godoc -http=:6060 可以查看手册了 http://localhost:6060/blog/go-slices-usage-and-internals
* 写一个字符串反转的例子 参考手册 http://zhanghum:6060/pkg/strings/#Split (zhanghum是我的主机名) // String project main.go package main import ( "fmt" "strings" ) func strrev(s string) string { a := strings.Split(s, "") i := 0 j := len(a) - 1 for i < j { tmp := a[i] a[i] = a[j] a[j] = tmp i++ j-- } return strings.Join(a, "") } func main() { s := strrev("Hello world!") fmt.Println(s) } output: C:/go/bin/go.exe build -i [J:/gocode/src/String] 成功: 进程退出代码 0.
