# inject
--
import "github.com/codegangsta/inject"
Package inject provides utilities for mapping and injecting dependencies in
various ways.
Language Translations:
* [简体中文](translations/README_zh_cn.md)
## Usage
#### func InterfaceOf
```go
func InterfaceOf(value interface{}) reflect.Type
```
InterfaceOf dereferences a pointer to an Interface type. It panics if value is
not an pointer to an interface.
#### type Applicator
```go
type Applicator interface {
// Maps dependencies in the Type map to each field in the struct
// that is tagged with 'inject'. Returns an error if the injection
// fails.
Apply(interface{}) error
}
```
Applicator represents an interface for mapping dependencies to a struct.
#### type Injector
```go
type Injector interface {
Applicator
Invoker
TypeMapper
// SetParent sets the parent of the injector. If the injector cannot find a
// dependency in its Type map it will check its parent before returning an
// error.
SetParent(Injector)
}
```
Injector represents an interface for mapping and injecting dependencies into
structs and function arguments.
#### func New
```go
func New() Injector
```
New returns a new Injector.
#### type Invoker
```go
type Invoker interface {
// Invoke attempts to call the interface{} provided as a function,
// providing dependencies for function arguments based on Type. Returns
// a slice of reflect.Value representing the returned values of the function.
// Returns an error if the injection fails.
Invoke(interface{}) ([]reflect.Value, error)
}
```
Invoker represents an interface for calling functions via reflection.
#### type TypeMapper
```go
type TypeMapper interface {
// Maps the interface{} value based on its immediate type from reflect.TypeOf.
Map(interface{}) TypeMapper
// Maps the interface{} value based on the pointer of an Interface provided.
// This is really only useful for mapping a value as an interface, as interfaces
// cannot at this time be referenced directly without a pointer.
MapTo(interface{}, interface{}) TypeMapper
// Provides a possibility to directly insert a mapping based on type and value.
// This makes it possible to directly map type arguments not possible to instantiate
// with reflect like unidirectional channels.
Set(reflect.Type, reflect.Value) TypeMapper
// Returns the Value that is mapped to the current type. Returns a zeroed Value if
// the Type has not been mapped.
Get(reflect.Type) reflect.Value
}
```
TypeMapper represents an interface for mapping interface{} values based on type.

# inject
--
import "github.com/codegangsta/inject"
inject包提供了多种对实体的映射和依赖注入方式。
## 用法
#### func InterfaceOf
```go
func InterfaceOf(value interface{}) reflect.Type
```
函数InterfaceOf返回指向接口类型的指针。如果传入的value值不是指向接口的指针，将抛出一个panic异常。
#### type Applicator
```go
type Applicator interface {
// 在Type map中维持对结构体中每个域的引用并用'inject'来标记
// 如果注入失败将会返回一个error.
Apply(interface{}) error
}
```
Applicator接口表示到结构体的依赖映射关系。
#### type Injector
```go
type Injector interface {
Applicator
Invoker
TypeMapper
// SetParent用来设置父injector. 如果在当前injector的Type map中找不到依赖，
// 将会继续从它的父injector中找，直到返回error.
SetParent(Injector)
}
```
Injector接口表示对结构体、函数参数的映射和依赖注入。
#### func New
```go
func New() Injector
```
New创建并返回一个Injector.
#### type Invoker
```go
type Invoker interface {
// Invoke尝试将interface{}作为一个函数来调用，并基于Type为函数提供参数。
// 它将返回reflect.Value的切片，其中存放原函数的返回值。
// 如果注入失败则返回error.
Invoke(interface{}) ([]reflect.Value, error)
}
```
Invoker接口表示通过反射进行函数调用。
#### type TypeMapper
```go
type TypeMapper interface {
// 基于调用reflect.TypeOf得到的类型映射interface{}的值。
Map(interface{}) TypeMapper
// 基于提供的接口的指针映射interface{}的值。
// 该函数仅用来将一个值映射为接口，因为接口无法不通过指针而直接引用到。
MapTo(interface{}, interface{}) TypeMapper
// 为直接插入基于类型和值的map提供一种可能性。
// 它使得这一类直接映射成为可能：无法通过反射直接实例化的类型参数，如单向管道。
Set(reflect.Type, reflect.Value) TypeMapper
// 返回映射到当前类型的Value. 如果Type没被映射，将返回对应的零值。
Get(reflect.Type) reflect.Value
}
```
TypeMapper接口用来表示基于类型到接口值的映射。

## OLD README
First give you a full example, I will explain every command below.
session := sh.NewSession()
session.Env["PATH"] = "/usr/bin:/bin"
session.Stdout = os.Stdout
session.Stderr = os.Stderr
session.Alias("ll", "ls", "-l")
session.ShowCMD = true // enable for debug
var err error
err = session.Call("ll", "/")
if err != nil {
log.Fatal(err)
}
ret, err := session.Capture("pwd", sh.Dir("/home")) # wraper of session.Call
if err != nil {
log.Fatal(err)
}
# ret is "/home\n"
fmt.Println(ret)
create a new Session
session := sh.NewSession()
use alias like this
session.Alias("ll", "ls", "-l") # like alias ll='ls -l'
set current env like this
session.Env["BUILD_ID"] = "123" # like export BUILD_ID=123
set current directory
session.Set(sh.Dir("/")) # like cd /
pipe is also supported
session.Command("echo", "hello\tworld").Command("cut", "-f2")
// output should be "world"
session.Run()
test, the build in command support
session.Test("d", "dir") // test dir
session.Test("f", "file) // test regular file
with `Alias Env Set Call Capture Command` a shell scripts can be easily converted into golang program. below is a shell script.
#!/bin/bash -
#
export PATH=/usr/bin:/bin
alias ll='ls -l'
cd /usr
if test -d "local"
then
ll local | awk '{print $1, $NF}'
fi
convert to golang, will be
s := sh.NewSession()
s.Env["PATH"] = "/usr/bin:/bin"
s.Set(sh.Dir("/usr"))
s.Alias("ll", "ls", "-l")
if s.Test("d", "local") {
s.Command("ll", "local").Command("awk", "{print $1, $NF}").Run()
}

[![wercker status](https://app.wercker.com/status/009acbd4f00ccc6de7e2554e12a50d84/s "wercker status")](https://app.wercker.com/project/bykey/009acbd4f00ccc6de7e2554e12a50d84)
[![Go Walker](http://gowalker.org/api/v1/badge)](http://gowalker.org/github.com/codeskyblue/go-sh)
*If you depend on the old api, see tag: v.0.1*
install: `go get github.com/codeskyblue/go-sh`
Pipe Example:
package main
import "github.com/codeskyblue/go-sh"
func main() {
sh.Command("echo", "hello\tworld").Command("cut", "-f2").Run()
}
Because I like os/exec, `go-sh` is very much modelled after it. However, `go-sh` provides a better experience.
These are some of its features:
* keep the variable environment (e.g. export)
* alias support (e.g. alias in shell)
* remember current dir
* pipe command
* shell build-in commands echo & test
* timeout support
Examples are important:
sh: echo hello
go: sh.Command("echo", "hello").Run()
sh: export BUILD_ID=123
go: s = sh.NewSession().SetEnv("BUILD_ID", "123")
sh: alias ll='ls -l'
go: s = sh.NewSession().Alias('ll', 'ls', '-l')
sh: (cd /; pwd)
go: sh.Command("pwd", sh.Dir("/")).Run()
sh: test -d data || mkdir data
go: if ! sh.Test("dir", "data") { sh.Command("mkdir", "data").Run() }
sh: cat first second | awk '{print $1}'
go: sh.Command("cat", "first", "second").Command("awk", "{print $1}").Run()
sh: count=$(echo "one two three" | wc -w)
go: count, err := sh.Echo("one two three").Command("wc", "-w").Output()
sh(in ubuntu): timeout 1s sleep 3
go: c := sh.Command("sleep", "3"); c.Start(); c.WaitTimeout(time.Second) # default SIGKILL
go: out, err := sh.Command("sleep", "3").SetTimeout(time.Second).Output() # set session timeout and get output)
sh: echo hello | cat
go: out, err := sh.Command("cat").SetInput("hello").Output()
sh: cat # read from stdin
go: out, err := sh.Command("cat").SetStdin(os.Stdin).Output()
If you need to keep env and dir, it is better to create a session
session := sh.NewSession()
session.SetEnv("BUILD_ID", "123")
session.SetDir("/")
# then call cmd
session.Command("echo", "hello").Run()
# set ShowCMD to true for easily debug
session.ShowCMD = true
for more information, it better to see docs.

# the reason to use Go shell
Sometimes we need to write shell scripts, but shell scripts are not good at working cross platform, Go, on the other hand, is good at that. Is there a good way to use Go to write shell like scripts? Using go-sh we can do this now.

/*
Package go-sh is intented to make shell call with golang more easily.
Some usage is more similar to os/exec, eg: Run(), Output(), Command(name, args...)
But with these similar function, pipe is added in and this package also got shell-session support.
Why I love golang so much, because the usage of golang is simple, but the power is unlimited. I want to make this pakcage got the sample style like golang.
// just like os/exec
sh.Command("echo", "hello").Run()
// support pipe
sh.Command("echo", "hello").Command("wc", "-c").Run()
// create a session to store dir and env
sh.NewSession().SetDir("/").Command("pwd")
// shell buildin command - "test"
sh.Test("dir", "mydir")
// like shell call: (cd /; pwd)
sh.Command("pwd", sh.Dir("/")) same with sh.Command(sh.Dir("/"), "pwd")
// output to json and xml easily

Columnize
=========
Easy column-formatted output for golang
[![Build Status](https://travis-ci.org/ryanuber/columnize.svg)](https://travis-ci.org/ryanuber/columnize)
[![GoDoc](https://godoc.org/github.com/ryanuber/columnize?status.svg)](https://godoc.org/github.com/ryanuber/columnize)
Columnize is a really small Go package that makes building CLI's a little bit
easier. In some CLI designs, you want to output a number similar items in a
human-readable way with nicely aligned columns. However, figuring out how wide
to make each column is a boring problem to solve and eats your valuable time.
Here is an example:
```go
package main
import (
"fmt"
"github.com/ryanuber/columnize"
)
func main() {
output := []string{
"Name | Gender | Age",
"Bob | Male | 38",
"Sally | Female | 26",
}
result := columnize.SimpleFormat(output)
fmt.Println(result)
}
```
As you can see, you just pass in a list of strings. And the result:
```
Name Gender Age
Bob Male 38
Sally Female 26
```
Columnize is tolerant of missing or empty fields, or even empty lines, so
passing in extra lines for spacing should show up as you would expect.
Configuration
=============
Columnize is configured using a `Config`, which can be obtained by calling the
`DefaultConfig()` method. You can then tweak the settings in the resulting
`Config`:
```
config := columnize.DefaultConfig()
config.Delim = "|"
config.Glue = " "
config.Prefix = ""
config.Empty = ""
```
* `Delim` is the string by which columns of **input** are delimited
* `Glue` is the string by which columns of **output** are delimited
* `Prefix` is a string by which each line of **output** is prefixed
* `Empty` is a string used to replace blank values found in output
You can then pass the `Config` in using the `Format` method (signature below) to
have text formatted to your liking.
See the [godoc](https://godoc.org/github.com/ryanuber/columnize) page for usage.
