frpc 支持通过 `frpc status -c ./frpc.ini` 命令查看代理的状态信息，此功能需要在 frpc 中配置 admin 端口。
### 特权模式
### 端口白名单
由于从 v0.10.0 版本开始，所有 proxy 都在客户端配置，原先的特权模式是目前唯一支持的模式。
#### 端口白名单
为了防止端口被滥用，可以手动指定允许哪些端口被使用，在 frps.ini 中通过 privilege_allow_ports 来指定：

docopt-go
=========
[![Build Status](https://travis-ci.org/docopt/docopt.go.svg?branch=master)](https://travis-ci.org/docopt/docopt.go)
[![Coverage Status](https://coveralls.io/repos/docopt/docopt.go/badge.png)](https://coveralls.io/r/docopt/docopt.go)
[![GoDoc](https://godoc.org/github.com/docopt/docopt.go?status.png)](https://godoc.org/github.com/docopt/docopt.go)
An implementation of [docopt](http://docopt.org/) in the
[Go](http://golang.org/) programming language.
**docopt** helps you create *beautiful* command-line interfaces easily:
```go
package main
import (
"fmt"
"github.com/docopt/docopt-go"
)
func main() {
usage := `Naval Fate.
Usage:
naval_fate ship new <name>...
naval_fate ship <name> move <x> <y> [--speed=<kn>]
naval_fate ship shoot <x> <y>
naval_fate mine (set|remove) <x> <y> [--moored|--drifting]
naval_fate -h | --help
naval_fate --version
Options:
-h --help Show this screen.
--version Show version.
--speed=<kn> Speed in knots [default: 10].
--moored Moored (anchored) mine.
--drifting Drifting mine.`
arguments, _ := docopt.Parse(usage, nil, true, "Naval Fate 2.0", false)
fmt.Println(arguments)
}
```
**docopt** parses command-line arguments based on a help message. Don't
write parser code: a good help message already has all the necessary
information in it.
## Installation
⚠ Use the alias “docopt-go”. To use docopt in your Go code:
```go
import "github.com/docopt/docopt-go"
```
To install docopt according to your `$GOPATH`:
```console
$ go get github.com/docopt/docopt-go
```
## API
```go
func Parse(doc string, argv []string, help bool, version string,
optionsFirst bool, exit ...bool) (map[string]interface{}, error)
```
Parse `argv` based on the command-line interface described in `doc`.
Given a conventional command-line help message, docopt creates a parser and
processes the arguments. See
https://github.com/docopt/docopt#help-message-format for a description of the
help message format. If `argv` is `nil`, `os.Args[1:]` is used.
docopt returns a map of option names to the values parsed from `argv`, and an
error or `nil`.
More documentation for docopt is available at
[GoDoc.org](https://godoc.org/github.com/docopt/docopt.go).
## Testing
All tests from the Python version are implemented and passing
at [Travis CI](https://travis-ci.org/docopt/docopt.go). New
language-agnostic tests have been added
to [test_golang.docopt](test_golang.docopt).
To run tests for docopt-go, use `go test`.

# mousetrap
mousetrap is a tiny library that answers a single question.
On a Windows machine, was the process invoked by someone double clicking on
the executable file while browsing in explorer?
### Motivation
Windows developers unfamiliar with command line tools will often "double-click"
the executable for a tool. Because most CLI tools print the help and then exit
when invoked without arguments, this is often very frustrating for those users.
mousetrap provides a way to detect these invocations so that you can provide
more helpful behavior and instructions on how to run the CLI tool. To see what
this looks like, both from an organizational and a technical perspective, see
https://inconshreveable.com/09-09-2014/sweat-the-small-stuff/
### The interface
The library exposes a single interface:
func StartedByExplorer() (bool)

# Overview
Cobra is a library providing a simple interface to create powerful modern CLI
interfaces similar to git & go tools.
Cobra is also an application that will generate your application scaffolding to rapidly
develop a Cobra-based application.
Cobra provides:
* Easy subcommand-based CLIs: `app server`, `app fetch`, etc.
* Fully POSIX-compliant flags (including short & long versions)
* Nested subcommands
* Global, local and cascading flags
* Easy generation of applications & commands with `cobra init appname` & `cobra add cmdname`
* Intelligent suggestions (`app srver`... did you mean `app server`?)
* Automatic help generation for commands and flags
* Automatic help flag recognition of `-h`, `--help`, etc.
* Automatically generated bash autocomplete for your application
* Automatically generated man pages for your application
* Command aliases so you can change things without breaking them
* The flexibility to define your own help, usage, etc.
* Optional tight integration with [viper](http://github.com/spf13/viper) for 12-factor apps
# Concepts
Cobra is built on a structure of commands, arguments & flags.
**Commands** represent actions, **Args** are things and **Flags** are modifiers for those actions.
The best applications will read like sentences when used. Users will know how
to use the application because they will natively understand how to use it.
The pattern to follow is
`APPNAME VERB NOUN --ADJECTIVE.`
or
`APPNAME COMMAND ARG --FLAG`
A few good real world examples may better illustrate this point.
In the following example, 'server' is a command, and 'port' is a flag:
hugo server --port=1313
In this command we are telling Git to clone the url bare.
git clone URL --bare
## Commands
Command is the central point of the application. Each interaction that
the application supports will be contained in a Command. A command can
have children commands and optionally run an action.
In the example above, 'server' is the command.
[More about cobra.Command](https://godoc.org/github.com/spf13/cobra#Command)
## Flags
A flag is a way to modify the behavior of a command. Cobra supports
fully POSIX-compliant flags as well as the Go [flag package](https://golang.org/pkg/flag/).
A Cobra command can define flags that persist through to children commands
and flags that are only available to that command.
In the example above, 'port' is the flag.
Flag functionality is provided by the [pflag
library](https://github.com/spf13/pflag), a fork of the flag standard library
which maintains the same interface while adding POSIX compliance.
# Installing
Using Cobra is easy. First, use `go get` to install the latest version
of the library. This command will install the `cobra` generator executable
along with the library and its dependencies:
go get -u github.com/spf13/cobra/cobra
Next, include Cobra in your application:
```go
import "github.com/spf13/cobra"
```
# Getting Started
While you are welcome to provide your own organization, typically a Cobra-based
application will follow the following organizational structure:
```
▾ appName/
▾ cmd/
add.go
your.go
commands.go
here.go
main.go
```
In a Cobra app, typically the main.go file is very bare. It serves one purpose: initializing Cobra.
```go
package main
import (
"fmt"
"os"
"{pathToYourApp}/cmd"
)
func main() {
cmd.Execute()
}
```
## Using the Cobra Generator
Cobra provides its own program that will create your application and add any
commands you want. It's the easiest way to incorporate Cobra into your application.
[Here](https://github.com/spf13/cobra/blob/master/cobra/README.md) you can find more information about it.
## Using the Cobra Library
To manually implement Cobra you need to create a bare main.go file and a rootCmd file.
You will optionally provide additional commands as you see fit.
### Create rootCmd
Cobra doesn't require any special constructors. Simply create your commands.
Ideally you place this in app/cmd/root.go:
```go
var rootCmd = &cobra.Command{
Use: "hugo",
Short: "Hugo is a very fast static site generator",
Long: `A Fast and Flexible Static Site Generator built with
love by spf13 and friends in Go.
Complete documentation is available at http://hugo.spf13.com`,
Run: func(cmd *cobra.Command, args []string) {
// Do Stuff Here
},
}
func Execute() {
if err := rootCmd.Execute(); err != nil {
fmt.Println(err)
os.Exit(1)
}
}
```
You will additionally define flags and handle configuration in your init() function.
For example cmd/root.go:
```go
import (
"fmt"
"os"
homedir "github.com/mitchellh/go-homedir"
"github.com/spf13/cobra"
"github.com/spf13/viper"
)
func init() {
cobra.OnInitialize(initConfig)
rootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)")
rootCmd.PersistentFlags().StringVarP(&projectBase, "projectbase", "b", "", "base project directory eg. github.com/spf13/")
rootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "Author name for copyright attribution")
rootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "Name of license for the project (can provide `licensetext` in config)")
rootCmd.PersistentFlags().Bool("viper", true, "Use Viper for configuration")
viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
viper.BindPFlag("projectbase", rootCmd.PersistentFlags().Lookup("projectbase"))
viper.BindPFlag("useViper", rootCmd.PersistentFlags().Lookup("viper"))
viper.SetDefault("author", "NAME HERE <EMAIL ADDRESS>")
viper.SetDefault("license", "apache")
}
func initConfig() {
// Don't forget to read config either from cfgFile or from home directory!
if cfgFile != "" {
// Use config file from the flag.
viper.SetConfigFile(cfgFile)
} else {
// Find home directory.
home, err := homedir.Dir()
if err != nil {
fmt.Println(err)
os.Exit(1)
}
// Search config in home directory with name ".cobra" (without extension).
viper.AddConfigPath(home)
viper.SetConfigName(".cobra")
}
if err := viper.ReadInConfig(); err != nil {
fmt.Println("Can't read config:", err)
os.Exit(1)
}
}
```
### Create your main.go
With the root command you need to have your main function execute it.
Execute should be run on the root for clarity, though it can be called on any command.
In a Cobra app, typically the main.go file is very bare. It serves, one purpose, to initialize Cobra.
```go
package main
import (
"fmt"
"os"
"{pathToYourApp}/cmd"
)
func main() {
cmd.Execute()
}
```
### Create additional commands
Additional commands can be defined and typically are each given their own file
inside of the cmd/ directory.
If you wanted to create a version command you would create cmd/version.go and
populate it with the following:
```go
package cmd
import (
"fmt"
"github.com/spf13/cobra"
)
func init() {
rootCmd.AddCommand(versionCmd)
}
var versionCmd = &cobra.Command{
Use: "version",
Short: "Print the version number of Hugo",
Long: `All software has versions. This is Hugo's`,
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("Hugo Static Site Generator v0.9 -- HEAD")
},
}
```
## Working with Flags
Flags provide modifiers to control how the action command operates.
### Assign flags to a command
Since the flags are defined and used in different locations, we need to
define a variable outside with the correct scope to assign the flag to
work with.
```go
var Verbose bool
var Source string
```
There are two different approaches to assign a flag.
### Persistent Flags
A flag can be 'persistent' meaning that this flag will be available to the
command it's assigned to as well as every command under that command. For
global flags, assign a flag as a persistent flag on the root.
```go
rootCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output")
```
### Local Flags
A flag can also be assigned locally which will only apply to that specific command.
```go
rootCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from")
```
### Local Flag on Parent Commands
By default Cobra only parses local flags on the target command, any local flags on
parent commands are ignored. By enabling `Command.TraverseChildren` Cobra will
parse local flags on each command before executing the target command.
```go
command := cobra.Command{
Use: "print [OPTIONS] [COMMANDS]",
TraverseChildren: true,
}
```
### Bind Flags with Config
You can also bind your flags with [viper](https://github.com/spf13/viper):
```go
var author string
func init() {
rootCmd.PersistentFlags().StringVar(&author, "author", "YOUR NAME", "Author name for copyright attribution")
viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
}
```
In this example the persistent flag `author` is bound with `viper`.
**Note**, that the variable `author` will not be set to the value from config,
when the `--author` flag is not provided by user.
More in [viper documentation](https://github.com/spf13/viper#working-with-flags).
### Required flags
Flags are optional by default. If instead you wish your command to report an error
when a flag has not been set, mark it as required:
```go
rootCmd.Flags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
rootCmd.MarkFlagRequired("region")
```
## Positional and Custom Arguments
Validation of positional arguments can be specified using the `Args` field
of `Command`.
The following validators are built in:
- `NoArgs` - the command will report an error if there are any positional args.
- `ArbitraryArgs` - the command will accept any args.
- `OnlyValidArgs` - the command will report an error if there are any positional args that are not in the `ValidArgs` field of `Command`.
- `MinimumNArgs(int)` - the command will report an error if there are not at least N positional args.
- `MaximumNArgs(int)` - the command will report an error if there are more than N positional args.
- `ExactArgs(int)` - the command will report an error if there are not exactly N positional args.
- `RangeArgs(min, max)` - the command will report an error if the number of args is not between the minimum and maximum number of expected args.
An example of setting the custom validator:
```go
var cmd = &cobra.Command{
Short: "hello",
Args: func(cmd *cobra.Command, args []string) error {
if len(args) < 1 {
return errors.New("requires at least one arg")
}
if myapp.IsValidColor(args[0]) {
return nil
}
return fmt.Errorf("invalid color specified: %s", args[0])
},
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("Hello, World!")
},
}
```
## Example
In the example below, we have defined three commands. Two are at the top level
and one (cmdTimes) is a child of one of the top commands. In this case the root
is not executable meaning that a subcommand is required. This is accomplished
by not providing a 'Run' for the 'rootCmd'.
We have only defined one flag for a single command.
More documentation about flags is available at https://github.com/spf13/pflag
```go
package main
import (
"fmt"
"strings"
"github.com/spf13/cobra"
)
func main() {
var echoTimes int
var cmdPrint = &cobra.Command{
Use: "print [string to print]",
Short: "Print anything to the screen",
Long: `print is for printing anything back to the screen.
For many years people have printed back to the screen.`,
Args: cobra.MinimumNArgs(1),
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("Print: " + strings.Join(args, " "))
},
}
var cmdEcho = &cobra.Command{
Use: "echo [string to echo]",
Short: "Echo anything to the screen",
Long: `echo is for echoing anything back.
Echo works a lot like print, except it has a child command.`,
Args: cobra.MinimumNArgs(1),
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("Print: " + strings.Join(args, " "))
},
}
var cmdTimes = &cobra.Command{
Use: "times [# times] [string to echo]",
Short: "Echo anything to the screen more times",
Long: `echo things multiple times back to the user by providing
a count and a string.`,
Args: cobra.MinimumNArgs(1),
Run: func(cmd *cobra.Command, args []string) {
for i := 0; i < echoTimes; i++ {
fmt.Println("Echo: " + strings.Join(args, " "))
}
},
}
cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input")
var rootCmd = &cobra.Command{Use: "app"}
rootCmd.AddCommand(cmdPrint, cmdEcho)
cmdEcho.AddCommand(cmdTimes)
rootCmd.Execute()
}
```
For a more complete example of a larger application, please checkout [Hugo](http://gohugo.io/).
## Help Command
Cobra automatically adds a help command to your application when you have subcommands.
This will be called when a user runs 'app help'. Additionally, help will also
support all other commands as input. Say, for instance, you have a command called
'create' without any additional configuration; Cobra will work when 'app help
create' is called. Every command will automatically have the '--help' flag added.
### Example
The following output is automatically generated by Cobra. Nothing beyond the
command and flag definitions are needed.
$ cobra help
Cobra is a CLI library for Go that empowers applications.
This application is a tool to generate the needed files
to quickly create a Cobra application.
Usage:
cobra [command]
Available Commands:
add Add a command to a Cobra Application
help Help about any command
init Initialize a Cobra Application
Flags:
-a, --author string author name for copyright attribution (default "YOUR NAME")
--config string config file (default is $HOME/.cobra.yaml)
-h, --help help for cobra
-l, --license string name of license for the project
--viper use Viper for configuration (default true)
Use "cobra [command] --help" for more information about a command.
Help is just a command like any other. There is no special logic or behavior
around it. In fact, you can provide your own if you want.
### Defining your own help
You can provide your own Help command or your own template for the default command to use
with following functions:
```go
cmd.SetHelpCommand(cmd *Command)
cmd.SetHelpFunc(f func(*Command, []string))
cmd.SetHelpTemplate(s string)
```
The latter two will also apply to any children commands.
## Usage Message
When the user provides an invalid flag or invalid command, Cobra responds by
showing the user the 'usage'.
### Example
You may recognize this from the help above. That's because the default help
embeds the usage as part of its output.
$ cobra --invalid
Error: unknown flag: --invalid
Usage:
cobra [command]
Available Commands:
add Add a command to a Cobra Application
help Help about any command
init Initialize a Cobra Application
Flags:
-a, --author string author name for copyright attribution (default "YOUR NAME")
--config string config file (default is $HOME/.cobra.yaml)
-h, --help help for cobra
-l, --license string name of license for the project
--viper use Viper for configuration (default true)
Use "cobra [command] --help" for more information about a command.
### Defining your own usage
You can provide your own usage function or template for Cobra to use.
Like help, the function and template are overridable through public methods:
```go
cmd.SetUsageFunc(f func(*Command) error)
cmd.SetUsageTemplate(s string)
```
## Version Flag
Cobra adds a top-level '--version' flag if the Version field is set on the root command.
Running an application with the '--version' flag will print the version to stdout using
the version template. The template can be customized using the
`cmd.SetVersionTemplate(s string)` function.
## PreRun and PostRun Hooks
It is possible to run functions before or after the main `Run` function of your command. The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistentPostRun` and `PostRun` will be executed after `Run`. The `Persistent*Run` functions will be inherited by children if they do not declare their own. These functions are run in the following order:
- `PersistentPreRun`
- `PreRun`
- `Run`
- `PostRun`
- `PersistentPostRun`
An example of two commands which use all of these features is below. When the subcommand is executed, it will run the root command's `PersistentPreRun` but not the root command's `PersistentPostRun`:
```go
package main
import (
"fmt"
"github.com/spf13/cobra"
)
func main() {
var rootCmd = &cobra.Command{
Use: "root [sub]",
Short: "My root command",
PersistentPreRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside rootCmd PersistentPreRun with args: %v\n", args)
},
PreRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside rootCmd PreRun with args: %v\n", args)
},
Run: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside rootCmd Run with args: %v\n", args)
},
PostRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside rootCmd PostRun with args: %v\n", args)
},
PersistentPostRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside rootCmd PersistentPostRun with args: %v\n", args)
},
}
var subCmd = &cobra.Command{
Use: "sub [no options!]",
Short: "My subcommand",
PreRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside subCmd PreRun with args: %v\n", args)
},
Run: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside subCmd Run with args: %v\n", args)
},
PostRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside subCmd PostRun with args: %v\n", args)
},
PersistentPostRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside subCmd PersistentPostRun with args: %v\n", args)
},
}
rootCmd.AddCommand(subCmd)
rootCmd.SetArgs([]string{""})
rootCmd.Execute()
fmt.Println()
rootCmd.SetArgs([]string{"sub", "arg1", "arg2"})
rootCmd.Execute()
}
```
Output:
```
Inside rootCmd PersistentPreRun with args: []
Inside rootCmd PreRun with args: []
Inside rootCmd Run with args: []
Inside rootCmd PostRun with args: []

## Suggestions when "unknown command" happens
Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example:
```
$ hugo srever
Error: unknown command "srever" for "hugo"
Did you mean this?
server
Run 'hugo --help' for usage.
```
Suggestions are automatic based on every subcommand registered and use an implementation of [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance). Every registered command that matches a minimum distance of 2 (ignoring case) will be displayed as a suggestion.
If you need to disable suggestions or tweak the string distance in your command, use:
```go
command.DisableSuggestions = true
```
or
```go
command.SuggestionsMinimumDistance = 1
```
You can also explicitly set names for which a given command will be suggested using the `SuggestFor` attribute. This allows suggestions for strings that are not close in terms of string distance, but makes sense in your set of commands and for some which you don't want aliases. Example:
```
$ kubectl remove
Error: unknown command "remove" for "kubectl"
Did you mean this?
delete
Run 'kubectl help' for usage.
```
## Generating documentation for your command
Cobra can generate documentation based on subcommands, flags, etc. in the following formats:
- [Markdown](doc/md_docs.md)
- [ReStructured Text](doc/rest_docs.md)
- [Man Page](doc/man_docs.md)
## Generating bash completions
Cobra can generate a bash-completion file. If you add more information to your command, these completions can be amazingly powerful and flexible. Read more about it in [Bash Completions](bash_completions.md).

# Generating Bash Completions For Your Own cobra.Command
Generating bash completions from a cobra command is incredibly easy. An actual program which does so for the kubernetes kubectl binary is as follows:
```go
package main
import (
"io/ioutil"
"os"
"k8s.io/kubernetes/pkg/kubectl/cmd"
"k8s.io/kubernetes/pkg/kubectl/cmd/util"
)
func main() {
kubectl := cmd.NewKubectlCommand(util.NewFactory(nil), os.Stdin, ioutil.Discard, ioutil.Discard)
kubectl.GenBashCompletionFile("out.sh")
}
```
`out.sh` will get you completions of subcommands and flags. Copy it to `/etc/bash_completion.d/` as described [here](https://debian-administration.org/article/316/An_introduction_to_bash_completion_part_1) and reset your terminal to use autocompletion. If you make additional annotations to your code, you can get even more intelligent and flexible behavior.
## Creating your own custom functions
Some more actual code that works in kubernetes:
```bash
const (
bash_completion_func = `__kubectl_parse_get()
{
local kubectl_output out
if kubectl_output=$(kubectl get --no-headers "$1" 2>/dev/null); then
out=($(echo "${kubectl_output}" | awk '{print $1}'))
COMPREPLY=( $( compgen -W "${out[*]}" -- "$cur" ) )
fi
}
__kubectl_get_resource()
{
if [[ ${#nouns[@]} -eq 0 ]]; then
return 1
fi
__kubectl_parse_get ${nouns[${#nouns[@]} -1]}
if [[ $? -eq 0 ]]; then
return 0
fi
}
__custom_func() {
case ${last_command} in
kubectl_get | kubectl_describe | kubectl_delete | kubectl_stop)
__kubectl_get_resource
return
;;
*)
;;
esac
}
`)
```
And then I set that in my command definition:
```go
cmds := &cobra.Command{
Use: "kubectl",
Short: "kubectl controls the Kubernetes cluster manager",
Long: `kubectl controls the Kubernetes cluster manager.
Find more information at https://github.com/GoogleCloudPlatform/kubernetes.`,
Run: runHelp,
BashCompletionFunction: bash_completion_func,
}
```
The `BashCompletionFunction` option is really only valid/useful on the root command. Doing the above will cause `__custom_func()` to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`. `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`. So it will call `__kubectl_parse_get pod`. `__kubectl_parse_get` will actually call out to kubernetes and get any pods. It will then set `COMPREPLY` to valid pods!
## Have the completions code complete your 'nouns'
In the above example "pod" was assumed to already be typed. But if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them. Simplified code from `kubectl get` looks like:
```go
validArgs []string = { "pod", "node", "service", "replicationcontroller" }
cmd := &cobra.Command{
Use: "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
Short: "Display one or many resources",
Long: get_long,
Example: get_example,
Run: func(cmd *cobra.Command, args []string) {
err := RunGet(f, out, cmd, args)
util.CheckErr(err)
},
ValidArgs: validArgs,
}
```
Notice we put the "ValidArgs" on the "get" subcommand. Doing so will give results like
```bash
# kubectl get [tab][tab]
node pod replicationcontroller service
```
## Plural form and shortcuts for nouns
If your nouns have a number of aliases, you can define them alongside `ValidArgs` using `ArgAliases`:
```go
argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" }
cmd := &cobra.Command{
...
ValidArgs: validArgs,
ArgAliases: argAliases
}
```
The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by
the completion algorithm if entered manually, e.g. in:
```bash
# kubectl get rc [tab][tab]
backend frontend database
```
Note that without declaring `rc` as an alias, the completion algorithm would show the list of nouns
in this example again instead of the replication controllers.
## Mark flags as required
Most of the time completions will only show subcommands. But if a flag is required to make a subcommand work, you probably want it to show up when the user types [tab][tab]. Marking a flag as 'Required' is incredibly easy.
```go
cmd.MarkFlagRequired("pod")
cmd.MarkFlagRequired("container")
```
and you'll get something like
```bash
# kubectl exec [tab][tab][tab]
-c --container= -p --pod=
```
# Specify valid filename extensions for flags that take a filename
In this example we use --filename= and expect to get a json or yaml file as the argument. To make this easier we annotate the --filename flag with valid filename extensions.
```go
annotations := []string{"json", "yaml", "yml"}
annotation := make(map[string][]string)
annotation[cobra.BashCompFilenameExt] = annotations
flag := &pflag.Flag{
Name: "filename",
Shorthand: "f",
Usage: usage,
Value: value,
DefValue: value.String(),
Annotations: annotation,
}
cmd.Flags().AddFlag(flag)
```
Now when you run a command with this filename flag you'll get something like
```bash
# kubectl create -f
test/ example/ rpmbuild/
hello.yml test.json
```
So while there are many other files in the CWD it only shows me subdirs and those with valid extensions.
# Specify custom flag completion
Similar to the filename completion and filtering using cobra.BashCompFilenameExt, you can specify
a custom flag completion function with cobra.BashCompCustom:
```go
annotation := make(map[string][]string)
annotation[cobra.BashCompFilenameExt] = []string{"__kubectl_get_namespaces"}
flag := &pflag.Flag{
Name: "namespace",
Usage: usage,
Annotations: annotation,
}
cmd.Flags().AddFlag(flag)
```
In addition add the `__handle_namespace_flag` implementation in the `BashCompletionFunction`
value, e.g.:
```bash
__kubectl_get_namespaces()
{
local template
template="{{ range .items }}{{ .metadata.name }} {{ end }}"
local kubectl_out
if kubectl_out=$(kubectl get -o template --template="${template}" namespace 2>/dev/null); then
COMPREPLY=( $( compgen -W "${kubectl_out}[*]" -- "$cur" ) )
fi
}
```
# Using bash aliases for commands
You can also configure the `bash aliases` for the commands and they will also support completions.
```bash
alias aliasname=origcommand
complete -o default -F __start_origcommand aliasname
# and now when you run `aliasname` completion will make
# suggestions as it did for `origcommand`.
$) aliasname <tab><tab>
completion firstcommand secondcommand
```
