go-gitcmd

Go (golang) package providing for tiny git command wrapper.

Installation

To install go-gitcmd, simply run:

$ go get -u github.com/tsuyoshiwada/go-gitcmd

Usage

It is the simplest example.

package main

import (
	"log"
	"github.com/tsuyoshiwada/go-gitcmd"
)

func main() {
	git := gitcmd.New(nil) // or `git := gitcmd.New(&Config{Bin: "/your/custom/git/bin"})`

	out, err := git.Exec("rev-parse", "--git-dir")
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(out) // ".git"
}

See godoc for API detail 👍

How to Mock

Since Client is an interface, it can easily be Mocked.

type MockClient struct {
	gitcmd.Client // Interface embedding
	ReturnCanExec        func() error
	ReturnExec           func(string, ...string) (string, error)
	ReturnInsideWorkTree func() error
}

func (m *MockClient) CanExec() error {
	return m.ReturnCanExec()
}

func (m *MockClient) Exec(subcmd string, args ...string) (string, error) {
	return m.ReturnExec(subcmd, args...)
}

func (m *MockClient) InsideWorkTree() error {
	return m.ReturnInsideWorkTree()
}

func main() {
	git := &MockClient{}

	// Set `InsideWorkTree()` mock function
	git.ReturnInsideWorkTree = func() error {
		return errors.New("error...")
	}

	err := git.InsideWorkTree()
	fmt.Println(err.Error()) // "error..."
}
