$ gg git logrus git status

// make file template
$ gg make

lib section format: {repo_id}={repo_url},{branch/tag/commit},{branch name/tag name/commit hash}

Build

Modify OSS in Makefile if there is no cross compile environment.

$ make
$ sudo ln -s ~/dev/gg/dist/{OS}/gg /usr/bin/gg

Usage

1.create project directory

$ mkdir myproject
$ cd myproject

2.create bin/src/pkg and makefile

$ gg mkdirs
$ gg make

3.create gg config in .gg/env, and add a dependency

$ gg setenv
$ cat gg
$ echo "example=https://github.com/golang/example.git,branch,master" >> .gg/env
$ gg env
#########################
## download dependency ##
#########################
$ gg get

4.create src/main.go

gg:{myproject} {user}$ vim src/main.go

package main

import (
	"fmt"
	"github.com/golang/example/stringutil"
)

func main() {
	fmt.Println(stringutil.Reverse("12345"))
}

5.build

gg:{myproject} {user}$ make

6.run

gg:{myproject} {user}$ dist/darwin_amd64/myproject

Misc

GOROOT environment variable is the path of Go binary distributions, and GOPATH specifies the location of your workspace.
