"""Dataflow pipeline for batch prediction in Kubeflow.
The output data is the prediction results in the format of a list of json
object. Each key of the object is the name of the tensor to fetch. The value is
the value of that tensor.
This tool expects as input a file or file pattern. Currently it supports two
kinds of inputs.
1) Input file(s) in TFRecord format. Each record contains a string that can
be consumed by the graph.
2) Input files(s) in Text/JSON format. Each line contains either
a) numbers, or (possibly nested) lists of numbers.
b) a string that can be consumed by the graph.
Note that the graph can accept one or more input tensor values. The tensor
names should be logical names that are specified when constructing the graph
where the map of logical tensor names to physical tensor names are provided
by user code.
One should also specify the model location where the model in SavedModel format
are saved. The location can be on local disk (when running locally) or on GCS.
Another mandatory flag is the output location, which is a directory on local
disk or on GCS.
This program can be used to run the pipeline or to generate a Dataflow template
for later use.

## Overview
The FATE-Operator makes it easy to deploy and run federated machine learning (FML) jobs on Kubernetes. It is a early version, all suggestions and feature requests are valueables for us. Raising issues is appreciate.
## Background
Federated machine learning (FML) is a machine learning setting where many clients (e.g. mobile devices or organizations) collaboratively train a model under the coordination of a central server while keeping the training data decentralized. Only the encrypted mediate parameters are exchanged between clients with MPC or homomorphic encryption.
FML has received significant interest recently, because of its effectiveness to solve data silos and data privacy preserving problems. Companies participated in federated machine learning include 4Paradigm, Ant Financial, Data Republic, Google, Huawei, Intel, JD.com, Microsoft, Nvidia, OpenMind, Pingan Technology, Sharemind, Tencent, VMware, Webank etc.
Depending on the differences in features and sample data space, federated machine learning can be classified into _horizontal federated machine learning_, _vertical federated machine learning_ and _federated transfer learning_. Horizontal federated machine learning is also called sample-based federated machine learning, which means data sets share the same feature space but have different samples. With horizontal federated machine learning, we can gather the relatively small or partial datasets into a big one to increase the performance of trained models. Vertical federated machine learning is applicable to the cases where there are two datasets with different feature space but share same sample ID. With vertical federated machine learning we can train a model with attributes from different organizations for a full profile. Vertical federated machine learning is required to redesign most of machine learning algorithms. Federated transfer learning applies to scenarios where there are two datasets with different features space but also different samples.
[FATE (Federated AI Technology Enabler)](https://fate.fedai.org) is an open source project initialized by Webank, [now hosted at the Linux Foundation](https://fate.fedai.org/2019/09/18/first-digital-only-bank-in-china-joins-linux-foundation/). FATE is the only open source FML framework that supports both horizontal and vertical FML currently. The architecture design of FATE is focused on providing FML platform for enterprises. [KubeFATE](https://github.com/FederatedAI/KubeFATE) is an open source project to deploy FATE on Kubernetes and is a proven effective solution for FML use cases.
More technologies of Federated machine learning, please refer to [Reference section](#reference)
**The design proposal of fate-operator can be found in [kubeflow/community/fate-operator-proposal.md](https://github.com/kubeflow/community/blob/master/proposals/fate-operator-proposal.md).**
## Quick user guide
### Installation
The fate-operator can be installed by following steps.
#### Install CRDs to Kubernetes
```bash
make install
```
#### Uninstall CRDs from Kubernetes
```bash
make uninstall
```
#### Building controller images
The Docker images are built and pushed to Dockerhub.
[fate-operator](https://hub.docker.com/r/federatedai/fate-controller)
Alternatively, we can build the images manually by commands,
```bash
make docker-build
```
#### Deploying controller
```bash
make deploy
```
### Deploying KubeFATE
KubeFATE is the infrastructure management service for multiple FATE clusters in one organization. It will only deploy once. To deploy a KubeFATE service, we use the YAML refer to [app_v1beta1_kubefate.yaml](./config/samples/app_v1beta1_kubefate.yaml) as an example,
```bash
kubectl create -f ./config/samples/app_v1beta1_kubefate.yaml
```
### Deploying FATE
FATE is the cluster we run FML jobs. To deploy a FATE cluster, we use YAML refer to [app_v1beta1_fatecluster.yaml](./config/samples/app_v1beta1_fatecluster.yaml) as an example,
```bash
kubectl create -f ./config/samples/app_v1beta1_fatecluster.yaml
```
### Submitting an FML Job
Once KubeFATE and FATE cluster deployed, we can submit a FML job with `FateJob` config file. In current version, the FATE Job is defined by `DSL pipeline` and `Module Config` two parts. The details refer to [app_v1beta1_fatejob.yaml](./config/samples/app_v1beta1_fatejob.yaml).
```bash
kubectl create -f ./config/samples/app_v1beta1_fatejob.yaml
```
In this example, only a `secure add` operation will be processed. For more example, we can refer to [FATE Examples](https://github.com/FederatedAI/FATE/tree/master/examples/federatedml-1.x-examples). In each example, the files end with `_dsl`, e.g. <https://github.com/FederatedAI/FATE/blob/master/examples/federatedml-1.x-examples/hetero_linear_regression/test_hetero_linr_cv_job_dsl.json> is the job pipeline and what should be put in `pipeline` field; and the files end with `_conf`, e.g. <https://github.com/FederatedAI/FATE/blob/master/examples/federatedml-1.x-examples/hetero_linear_regression/test_hetero_linr_cv_job_conf.json> is the config of each components and what should be put in `modulesConf` field.
### Checking created resource status
The status of created resource can be monitor with `kubectl get` command,
```bash
kubectl get kubefate,fatecluster,fatejob -A -o yaml
```

[TOML](https://github.com/toml-lang/toml) parser and encoder library for [Golang](http://golang.org/).
This library is compatible with TOML version [v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md).
## Installation
go get -u github.com/naoina/toml
## Usage
The following TOML save as `example.toml`.
```toml
# This is a TOML document. Boom.
title = "TOML Example"
[owner]
name = "Lance Uppercut"
dob = 1979-05-27T07:32:00-08:00 # First class dates? Why not?
[database]
server = "192.168.1.1"
ports = [ 8001, 8001, 8002 ]
connection_max = 5000
enabled = true
[servers]
# You can indent as you please. Tabs or spaces. TOML don't care.
[servers.alpha]
ip = "10.0.0.1"
dc = "eqdc10"
[servers.beta]
ip = "10.0.0.2"
dc = "eqdc10"
[clients]
data = [ ["gamma", "delta"], [1, 2] ]
# Line breaks are OK when inside arrays
hosts = [
"alpha",
"omega"
]
```
Then above TOML will mapping to `tomlConfig` struct using `toml.Unmarshal`.
```go
package main
import (
"io/ioutil"
"os"
"time"
"github.com/naoina/toml"
)
type tomlConfig struct {
Title string
Owner struct {
Name string
Dob time.Time
}
Database struct {
Server string
Ports []int
ConnectionMax uint
Enabled bool
}
Servers map[string]ServerInfo
Clients struct {
Data [][]interface{}
Hosts []string
}
}
type ServerInfo struct {
IP net.IP
DC string
}
func main() {
f, err := os.Open("example.toml")
if err != nil {
panic(err)
}
defer f.Close()
var config Config
if err := toml.NewDecoder(f).Decode(&config); err != nil {
panic(err)
}
// then to use the unmarshaled config...
fmt.Println("IP of server 'alpha':", config.Servers["alpha"].IP)
}
```
## Mappings
A key and value of TOML will map to the corresponding field.
The fields of struct for mapping must be exported.
The rules of the mapping of key are following:
#### Exact matching
```toml
timeout_seconds = 256
```
```go
type Config struct {
Timeout_seconds int
}
```
#### Camelcase matching
```toml
server_name = "srv1"
```
```go
type Config struct {
ServerName string
}
```
#### Uppercase matching
```toml
ip = "10.0.0.1"
```
```go
type Config struct {
IP string
}
```
See the following examples for the value mappings.
### String
```toml
val = "string"
```
```go
type Config struct {
Val string
}
```
### Integer
```toml
val = 100
```
```go
type Config struct {
Val int
}
```
All types that can be used are following:
* int8 (from `-128` to `127`)
* int16 (from `-32768` to `32767`)
* int32 (from `-2147483648` to `2147483647`)
* int64 (from `-9223372036854775808` to `9223372036854775807`)
* int (same as `int32` on 32bit environment, or `int64` on 64bit environment)
* uint8 (from `0` to `255`)
* uint16 (from `0` to `65535`)
* uint32 (from `0` to `4294967295`)
* uint64 (from `0` to `18446744073709551615`)
* uint (same as `uint` on 32bit environment, or `uint64` on 64bit environment)
### Float
```toml
val = 3.1415
```
```go
type Config struct {
Val float32
}
```
All types that can be used are following:
* float32
* float64
### Boolean
```toml
val = true
```
```go
type Config struct {
Val bool
}
```
### Datetime
```toml
val = 2014-09-28T21:27:39Z
```
```go
type Config struct {
Val time.Time
}
```
### Array
```toml
val = ["a", "b", "c"]
```
```go
type Config struct {
Val []string
}
```
Also following examples all can be mapped:
```toml
val1 = [1, 2, 3]
val2 = [["a", "b"], ["c", "d"]]
val3 = [[1, 2, 3], ["a", "b", "c"]]
val4 = [[1, 2, 3], [["a", "b"], [true, false]]]
```
```go
type Config struct {
Val1 []int
Val2 [][]string
Val3 [][]interface{}
Val4 [][]interface{}
}
```
### Table
```toml
[server]
type = "app"
[server.development]
ip = "10.0.0.1"
[server.production]
ip = "10.0.0.2"
```
```go
type Config struct {
Server map[string]Server
}
type Server struct {
IP string
}
```
You can also use the following struct instead of map of struct.
```go
type Config struct {
Server struct {
Development Server
Production Server
}
}
type Server struct {
IP string
}
```
### Array of Tables
```toml
[[fruit]]
name = "apple"
[fruit.physical]
color = "red"
shape = "round"
[[fruit.variety]]
name = "red delicious"
[[fruit.variety]]
name = "granny smith"
[[fruit]]
name = "banana"
[[fruit.variety]]
name = "plantain"
```
```go
type Config struct {
Fruit []struct {
Name string
Physical struct {
Color string
Shape string
}
Variety []struct {
Name string
}
}
}
```
### Using the `encoding.TextUnmarshaler` interface
Package toml supports `encoding.TextUnmarshaler` (and `encoding.TextMarshaler`). You can
use it to apply custom marshaling rules for certain types. The `UnmarshalText` method is
called with the value text found in the TOML input. TOML strings are passed unquoted.
```toml
duration = "10s"
```
```go
import time
type Duration time.Duration
// UnmarshalText implements encoding.TextUnmarshaler
func (d *Duration) UnmarshalText(data []byte) error {
duration, err := time.ParseDuration(string(data))
if err == nil {
*d = Duration(duration)
}
return err
}
// MarshalText implements encoding.TextMarshaler
func (d Duration) MarshalText() ([]byte, error) {
return []byte(time.Duration(d).String()), nil
}
type ConfigWithDuration struct {
Duration Duration
}
```
### Using the `toml.UnmarshalerRec` interface
You can also override marshaling rules specifically for TOML using the `UnmarshalerRec`
and `MarshalerRec` interfaces. These are useful if you want to control how structs or
arrays are handled. You can apply additional validation or set unexported struct fields.
Note: `encoding.TextUnmarshaler` and `encoding.TextMarshaler` should be preferred for
simple (scalar) values because they're also compatible with other formats like JSON or
YAML.
[See the UnmarshalerRec example](https://godoc.org/github.com/naoina/toml/#example_UnmarshalerRec).
### Using the `toml.Unmarshaler` interface
If you want to deal with raw TOML syntax, use the `Unmarshaler` and `Marshaler`
interfaces. Their input and output is raw TOML syntax. As such, these interfaces are
useful if you want to handle TOML at the syntax level.
[See the Unmarshaler example](https://godoc.org/github.com/naoina/toml/#example_Unmarshaler).

Cobra is both a library for creating powerful modern CLI applications as well as a program to generate applications and command files.
Cobra is used in many Go projects such as [Kubernetes](http://kubernetes.io/),
[Hugo](https://gohugo.io), and [Github CLI](https://github.com/cli/cli) to
name a few. [This list](./projects_using_cobra.md) contains a more extensive list of projects using Cobra.

# 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 shell autocomplete for your application (bash, zsh, fish, powershell)
* 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
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 (
"{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.Fprintln(os.Stderr, err)
os.Exit(1)
}
}
```
You will additionally define flags and handle configuration in your init() function.
For example cmd/root.go:
```go
package cmd
import (
"fmt"
"os"
homedir "github.com/mitchellh/go-homedir"
"github.com/spf13/cobra"
"github.com/spf13/viper"
)
var (
// Used for flags.
cfgFile string
userLicense string
rootCmd = &cobra.Command{
Use: "cobra",
Short: "A generator for Cobra based Applications",
Long: `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.`,
}
)
// Execute executes the root command.
func Execute() error {
return rootCmd.Execute()
}
func init() {
cobra.OnInitialize(initConfig)
rootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)")
rootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "author name for copyright attribution")
rootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "name of license for the project")
rootCmd.PersistentFlags().Bool("viper", true, "use Viper for configuration")
viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
viper.BindPFlag("useViper", rootCmd.PersistentFlags().Lookup("viper"))
viper.SetDefault("author", "NAME HERE <EMAIL ADDRESS>")
viper.SetDefault("license", "apache")
rootCmd.AddCommand(addCmd)
rootCmd.AddCommand(initCmd)
}
func er(msg interface{}) {
fmt.Println("Error:", msg)
os.Exit(1)
}
func initConfig() {
if cfgFile != "" {
// Use config file from the flag.
viper.SetConfigFile(cfgFile)
} else {
// Find home directory.
home, err := homedir.Dir()
if err != nil {
er(err)
}
// Search config in home directory with name ".cobra" (without extension).
viper.AddConfigPath(home)
viper.SetConfigName(".cobra")
}
viper.AutomaticEnv()
if err := viper.ReadInConfig(); err == nil {
fmt.Println("Using config file:", viper.ConfigFileUsed())
}
}
```
### 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 (
"{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")
},
}
```
### Returning and handling errors
If you wish to return an error to the caller of a command, `RunE` can be used.
```go
package cmd
import (
"fmt"
"github.com/spf13/cobra"
)
func init() {
rootCmd.AddCommand(tryCmd)
}
var tryCmd = &cobra.Command{
Use: "try",
Short: "Try and possibly fail at something",
RunE: func(cmd *cobra.Command, args []string) error {
if err := someFunc(); err != nil {
return err
}
return nil
},
}
```
The error can then be caught at the execute function call.
## 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
localCmd.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")
```
Or, for persistent flags:
```go
rootCmd.PersistentFlags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
rootCmd.MarkPersistentFlagRequired("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.
- `ExactValidArgs(int)` - the command will report an error if there are not exactly N positional args OR if there are any positional args that are not in the `ValidArgs` field of `Command`
- `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 a color argument")
}
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("Echo: " + strings.Join(args, " "))
},
}
var cmdTimes = &cobra.Command{
Use: "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: []
Inside rootCmd PersistentPostRun with args: []
Inside rootCmd PersistentPreRun with args: [arg1 arg2]
Inside subCmd PreRun with args: [arg1 arg2]
Inside subCmd Run with args: [arg1 arg2]
Inside subCmd PostRun with args: [arg1 arg2]
Inside subCmd PersistentPostRun with args: [arg1 arg2]
```
## 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. Read more about it in the [docs generation documentation](doc/README.md).
## Generating shell completions
Cobra can generate a shell-completion file for the following shells: Bash, Zsh, Fish, Powershell. If you add more information to your commands, these completions can be amazingly powerful and flexible. Read more about it in [Shell Completions](shell_completions.md).

Please refer to [Shell Completions](shell_completions.md) for details.
## Bash legacy dynamic completions
For backwards-compatibility, Cobra still supports its legacy dynamic completion solution (described below). Unlike the `ValidArgsFunction` solution, the legacy solution will only work for Bash shell-completion and not for other shells. This legacy solution can be used along-side `ValidArgsFunction` and `RegisterFlagCompletionFunc()`, as long as both solutions are not used for the same command. This provides a path to gradually migrate from the legacy solution to the new solution.
The legacy solution allows you to inject bash functions into the bash completion script. Those bash functions are responsible for providing the completion choices for your own completions.
Some 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
}
__kubectl_custom_func() {
case ${last_command} in
kubectl_get | kubectl_describe | kubectl_delete | kubectl_stop)
__kubectl_get_resource
return
;;
*)
;;
esac
}
`)
```
And then I set that in my command definition:
```go
cmds := &cobra.Command{
Use: "kubectl",
Short: "kubectl controls the Kubernetes cluster manager",
Long: `kubectl controls the Kubernetes cluster manager.
Find more information at https://github.com/GoogleCloudPlatform/kubernetes.`,
Run: runHelp,
BashCompletionFunction: bash_completion_func,
}
```
The `BashCompletionFunction` option is really only valid/useful on the root command. Doing the above will cause `__kubectl_custom_func()` (`__<command-use>_custom_func()`) to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__kubectl_customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__kubectl_custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`. `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`. So it will call `__kubectl_parse_get pod`. `__kubectl_parse_get` will actually call out to kubernetes and get any pods. It will then set `COMPREPLY` to valid pods!
Similarly, for flags:
```go
annotation := make(map[string][]string)
annotation[cobra.BashCompCustom] = []string{"__kubectl_get_namespaces"}
flag := &pflag.Flag{
Name: "namespace",
Usage: usage,
Annotations: annotation,
}
cmd.Flags().AddFlag(flag)
```
In addition add the `__kubectl_get_namespaces` implementation in the `BashCompletionFunction`
value, e.g.:
```bash
__kubectl_get_namespaces()
{
local template
template="{{ range .items }}{{ .metadata.name }} {{ end }}"
local kubectl_out
if kubectl_out=$(kubectl get -o template --template="${template}" namespace 2>/dev/null); then
COMPREPLY=( $( compgen -W "${kubectl_out}[*]" -- "$cur" ) )
fi
}
```

Cobra 1.1 standardized its zsh completion support to align it with its other shell completions. Although the API was kept backwards-compatible, some small changes in behavior were introduced.
### Deprecation summary
See further below for more details on these deprecations.
* `cmd.MarkZshCompPositionalArgumentFile(pos, []string{})` is no longer needed. It is therefore **deprecated** and silently ignored.
* `cmd.MarkZshCompPositionalArgumentFile(pos, glob[])` is **deprecated** and silently ignored.
* Instead use `ValidArgsFunction` with `ShellCompDirectiveFilterFileExt`.
* `cmd.MarkZshCompPositionalArgumentWords()` is **deprecated** and silently ignored.
* Instead use `ValidArgsFunction`.
### Behavioral changes
**Noun completion**
|Old behavior|New behavior|
|---|---|
|No file completion by default (opposite of bash)|File completion by default; use `ValidArgsFunction` with `ShellCompDirectiveNoFileComp` to turn off file completion on a per-argument basis|
|Completion of flag names without the `-` prefix having been typed|Flag names are only completed if the user has typed the first `-`|
`cmd.MarkZshCompPositionalArgumentFile(pos, []string{})` used to turn on file completion on a per-argument position basis|File completion for all arguments by default; `cmd.MarkZshCompPositionalArgumentFile()` is **deprecated** and silently ignored|
|`cmd.MarkZshCompPositionalArgumentFile(pos, glob[])` used to turn on file completion **with glob filtering** on a per-argument position basis (zsh-specific)|`cmd.MarkZshCompPositionalArgumentFile()` is **deprecated** and silently ignored; use `ValidArgsFunction` with `ShellCompDirectiveFilterFileExt` for file **extension** filtering (not full glob filtering)|
|`cmd.MarkZshCompPositionalArgumentWords(pos, words[])` used to provide completion choices on a per-argument position basis (zsh-specific)|`cmd.MarkZshCompPositionalArgumentWords()` is **deprecated** and silently ignored; use `ValidArgsFunction` to achieve the same behavior|
**Flag-value completion**
|Old behavior|New behavior|
|---|---|
|No file completion by default (opposite of bash)|File completion by default; use `RegisterFlagCompletionFunc()` with `ShellCompDirectiveNoFileComp` to turn off file completion|
|`cmd.MarkFlagFilename(flag, []string{})` and similar used to turn on file completion|File completion by default; `cmd.MarkFlagFilename(flag, []string{})` no longer needed in this context and silently ignored|
|`cmd.MarkFlagFilename(flag, glob[])` used to turn on file completion **with glob filtering** (syntax of `[]string{"*.yaml", "*.yml"}` incompatible with bash)|Will continue to work, however, support for bash syntax is added and should be used instead so as to work for all shells (`[]string{"yaml", "yml"}`)|
|`cmd.MarkFlagDirname(flag)` only completes directories (zsh-specific)|Has been added for all shells|
|Completion of a flag name does not repeat, unless flag is of type `*Array` or `*Slice` (not supported by bash)|Retained for `zsh` and added to `fish`|
|Completion of a flag name does not provide the `=` form (unlike bash)|Retained for `zsh` and added to `fish`|
**Improvements**
* Custom completion support (`ValidArgsFunction` and `RegisterFlagCompletionFunc()`)
* File completion by default if no other completions found
* Handling of required flags
* File extension filtering no longer mutually exclusive with bash usage
* Completion of directory names *within* another directory
* Support for `=` form of flags

Cobra can generate PowerShell completion scripts. Users need PowerShell version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1. They can then write the completions to a file and source this file from their PowerShell profile, which is referenced by the `$Profile` environment variable. See `Get-Help about_Profiles` for more info about PowerShell profiles.
*Note*: PowerShell completions have not (yet?) been aligned to Cobra's generic shell completion support. This implies the PowerShell completions are not as rich as for other shells (see [What's not yet supported](#whats-not-yet-supported)), and may behave slightly differently. They are still very useful for PowerShell users.
# What's supported
- Completion for subcommands using their `.Short` description
- Completion for non-hidden flags using their `.Name` and `.Shorthand`
# What's not yet supported
- Command aliases
- Required, filename or custom flags (they will work like normal flags)
- Custom completion scripts

Cobra can generate shell completions for multiple shells.
The currently supported shells are:
- Bash
- Zsh
- Fish
- PowerShell
If you are using the generator you can create a completion command by running
```bash
cobra add completion
```
and then modifying the generated `cmd/completion.go` file to look something like this
(writing the shell script to stdout allows the most flexible use):
```go
var completionCmd = &cobra.Command{
Use: "completion [bash|zsh|fish|powershell]",
Short: "Generate completion script",
Long: `To load completions:
Bash:
$ source <(yourprogram completion bash)
# To load completions for each session, execute once:
Linux:
$ yourprogram completion bash > /etc/bash_completion.d/yourprogram
MacOS:
$ yourprogram completion bash > /usr/local/etc/bash_completion.d/yourprogram
Zsh:
# If shell completion is not already enabled in your environment you will need
# to enable it. You can execute the following once:
$ echo "autoload -U compinit; compinit" >> ~/.zshrc
# To load completions for each session, execute once:
$ yourprogram completion zsh > "${fpath[1]}/_yourprogram"
# You will need to start a new shell for this setup to take effect.
Fish:
$ yourprogram completion fish | source
# To load completions for each session, execute once:
$ yourprogram completion fish > ~/.config/fish/completions/yourprogram.fish
`,
DisableFlagsInUseLine: true,
ValidArgs: []string{"bash", "zsh", "fish", "powershell"},
Args: cobra.ExactValidArgs(1),
Run: func(cmd *cobra.Command, args []string) {
switch args[0] {
case "bash":
cmd.Root().GenBashCompletion(os.Stdout)
case "zsh":
cmd.Root().GenZshCompletion(os.Stdout)
case "fish":
cmd.Root().GenFishCompletion(os.Stdout, true)
case "powershell":
cmd.Root().GenPowerShellCompletion(os.Stdout)
}
},
}
```
**Note:** The cobra generator may include messages printed to stdout for example if the config file is loaded, this will break the auto complete script so must be removed.
# Customizing completions
The generated completion scripts will automatically handle completing commands and flags. However, you can make your completions much more powerful by providing information to complete your program's nouns and flag values.
## Completion of nouns
### Static completion of nouns
Cobra allows you to provide a pre-defined list of completion choices for your nouns using the `ValidArgs` field.
For example, if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them.
Some 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` field on the `get` sub-command. Doing so will give results like:
```bash
$ kubectl get [tab][tab]
node pod replicationcontroller service
```
#### Aliases for nouns
If your nouns have 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 not know to show the list of
replication controllers following `rc`.
### Dynamic completion of nouns
In some cases it is not possible to provide a list of completions in advance. Instead, the list of completions must be determined at execution-time. In a similar fashion as for static completions, you can use the `ValidArgsFunction` field to provide a Go function that Cobra will execute when it needs the list of completion choices for the nouns of a command. Note that either `ValidArgs` or `ValidArgsFunction` can be used for a single cobra command, but not both.
Simplified code from `helm status` looks like:
```go
cmd := &cobra.Command{
Use: "status RELEASE_NAME",
Short: "Display the status of the named release",
Long: status_long,
RunE: func(cmd *cobra.Command, args []string) {
RunGet(args[0])
},
ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
if len(args) != 0 {
return nil, cobra.ShellCompDirectiveNoFileComp
}
return getReleasesFromCluster(toComplete), cobra.ShellCompDirectiveNoFileComp
},
}
```
Where `getReleasesFromCluster()` is a Go function that obtains the list of current Helm releases running on the Kubernetes cluster.
Notice we put the `ValidArgsFunction` on the `status` sub-command. Let's assume the Helm releases on the cluster are: `harbor`, `notary`, `rook` and `thanos` then this dynamic completion will give results like:
```bash
$ helm status [tab][tab]
harbor notary rook thanos
```
You may have noticed the use of `cobra.ShellCompDirective`. These directives are bit fields allowing to control some shell completion behaviors for your particular completion. You can combine them with the bit-or operator such as `cobra.ShellCompDirectiveNoSpace | cobra.ShellCompDirectiveNoFileComp`
```go
// Indicates that the shell will perform its default behavior after completions
// have been provided (this implies none of the other directives).
ShellCompDirectiveDefault
// Indicates an error occurred and completions should be ignored.
ShellCompDirectiveError
// Indicates that the shell should not add a space after the completion,
// even if there is a single completion provided.
ShellCompDirectiveNoSpace
// Indicates that the shell should not provide file completion even when
// no completion is provided.
ShellCompDirectiveNoFileComp
// Indicates that the returned completions should be used as file extension filters.
// For example, to complete only files of the form *.json or *.yaml:
// return []string{"yaml", "json"}, ShellCompDirectiveFilterFileExt
// For flags, using MarkFlagFilename() and MarkPersistentFlagFilename()
// is a shortcut to using this directive explicitly.
//
ShellCompDirectiveFilterFileExt
// Indicates that only directory names should be provided in file completion.
// For example:
// return nil, ShellCompDirectiveFilterDirs
// For flags, using MarkFlagDirname() is a shortcut to using this directive explicitly.
//
// To request directory names within another directory, the returned completions
// should specify a single directory name within which to search. For example,
// to complete directories within "themes/":
// return []string{"themes"}, ShellCompDirectiveFilterDirs
//
ShellCompDirectiveFilterDirs
```
***Note***: When using the `ValidArgsFunction`, Cobra will call your registered function after having parsed all flags and arguments provided in the command-line. You therefore don't need to do this parsing yourself. For example, when a user calls `helm status --namespace my-rook-ns [tab][tab]`, Cobra will call your registered `ValidArgsFunction` after having parsed the `--namespace` flag, as it would have done when calling the `RunE` function.
#### Debugging
Cobra achieves dynamic completion through the use of a hidden command called by the completion script. To debug your Go completion code, you can call this hidden command directly:
```bash
$ helm __complete status har<ENTER>
harbor
:4
Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
```
***Important:*** If the noun to complete is empty (when the user has not yet typed any letters of that noun), you must pass an empty parameter to the `__complete` command:
```bash
$ helm __complete status ""<ENTER>
harbor
notary
rook
thanos
:4
Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
```
Calling the `__complete` command directly allows you to run the Go debugger to troubleshoot your code. You can also add printouts to your code; Cobra provides the following functions to use for printouts in Go completion code:
```go
// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
// is set to a file path) and optionally prints to stderr.
cobra.CompDebug(msg string, printToStdErr bool) {
cobra.CompDebugln(msg string, printToStdErr bool)
// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
// is set to a file path) and to stderr.
cobra.CompError(msg string)
cobra.CompErrorln(msg string)
```
***Important:*** You should **not** leave traces that print directly to stdout in your completion code as they will be interpreted as completion choices by the completion script. Instead, use the cobra-provided debugging traces functions mentioned above.
## Completions for flags
### Mark flags as required
Most of the time completions will only show sub-commands. But if a flag is required to make a sub-command work, you probably want it to show up when the user types [tab][tab]. You can mark a flag as 'Required' like so:
```go
cmd.MarkFlagRequired("pod")
cmd.MarkFlagRequired("container")
```
and you'll get something like
```bash
$ kubectl exec [tab][tab]
-c --container= -p --pod=
```
### Specify dynamic flag completion
As for nouns, Cobra provides a way of defining dynamic completion of flags. To provide a Go function that Cobra will execute when it needs the list of completion choices for a flag, you must register the function using the `command.RegisterFlagCompletionFunc()` function.
```go
flagName := "output"
cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return []string{"json", "table", "yaml"}, cobra.ShellCompDirectiveDefault
})
```
Notice that calling `RegisterFlagCompletionFunc()` is done through the `command` with which the flag is associated. In our example this dynamic completion will give results like so:
```bash
$ helm status --output [tab][tab]
json table yaml
```
#### Debugging
You can also easily debug your Go completion code for flags:
```bash
$ helm __complete status --output ""
json
table
yaml
:4
Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
```
***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script. Instead, use the cobra-provided debugging traces functions mentioned further above.
### Specify valid filename extensions for flags that take a filename
To limit completions of flag values to file names with certain extensions you can either use the different `MarkFlagFilename()` functions or a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterFileExt`, like so:
```go
flagName := "output"
cmd.MarkFlagFilename(flagName, "yaml", "json")
```
or
```go
flagName := "output"
cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return []string{"yaml", "json"}, ShellCompDirectiveFilterFileExt})
```
### Limit flag completions to directory names
To limit completions of flag values to directory names you can either use the `MarkFlagDirname()` functions or a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterDirs`, like so:
```go
flagName := "output"
cmd.MarkFlagDirname(flagName)
```
or
```go
flagName := "output"
cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return nil, cobra.ShellCompDirectiveFilterDirs
})
```
To limit completions of flag values to directory names *within another directory* you can use a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterDirs` like so:
```go
flagName := "output"
cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return []string{"themes"}, cobra.ShellCompDirectiveFilterDirs
})
```
### Descriptions for completions
Both `zsh` and `fish` allow for descriptions to annotate completion choices. For commands and flags, Cobra will provide the descriptions automatically, based on usage information. For example, using zsh:
```
$ helm s[tab]
search -- search for a keyword in charts
show -- show information of a chart
status -- displays the status of the named release
```
while using fish:
```
$ helm s[tab]
search (search for a keyword in charts) show (show information of a chart) status (displays the status of the named release)
```
Cobra allows you to add annotations to your own completions. Simply add the annotation text after each completion, following a `\t` separator. This technique applies to completions returned by `ValidArgs`, `ValidArgsFunction` and `RegisterFlagCompletionFunc()`. For example:
```go
ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return []string{"harbor\tAn image registry", "thanos\tLong-term metrics"}, cobra.ShellCompDirectiveNoFileComp
}}
```
or
```go
ValidArgs: []string{"bash\tCompletions for bash", "zsh\tCompletions for zsh"}
```
## Bash completions
### Dependencies
The bash completion script generated by Cobra requires the `bash_completion` package. You should update the help text of your completion command to show how to install the `bash_completion` package ([Kubectl docs](https://kubernetes.io/docs/tasks/tools/install-kubectl/#enabling-shell-autocompletion))
### Aliases
You can also configure `bash` aliases for your program 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
```
### Bash legacy dynamic completions
For backwards-compatibility, Cobra still supports its bash legacy dynamic completion solution.
Please refer to [Bash Completions](bash_completions.md) for details.
## Zsh completions
Cobra supports native Zsh completion generated from the root `cobra.Command`.
The generated completion script should be put somewhere in your `$fpath` and be named
`_<yourProgram>`. You will need to start a new shell for the completions to become available.
Zsh supports descriptions for completions. Cobra will provide the description automatically,
based on usage information. Cobra provides a way to completely disable such descriptions by
using `GenZshCompletionNoDesc()` or `GenZshCompletionFileNoDesc()`. You can choose to make
this a configurable option to your users.
```
# With descriptions
$ helm s[tab]
search -- search for a keyword in charts
show -- show information of a chart
status -- displays the status of the named release
# Without descriptions
$ helm s[tab]
search show status
```
*Note*: Because of backwards-compatibility requirements, we were forced to have a different API to disable completion descriptions between `Zsh` and `Fish`.
### Limitations
* Custom completions implemented in Bash scripting (legacy) are not supported and will be ignored for `zsh` (including the use of the `BashCompCustom` flag annotation).
* You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`).
* The function `MarkFlagCustom()` is not supported and will be ignored for `zsh`.
* You should instead use `RegisterFlagCompletionFunc()`.
### Zsh completions standardization
Cobra 1.1 standardized its zsh completion support to align it with its other shell completions. Although the API was kept backwards-compatible, some small changes in behavior were introduced.
Please refer to [Zsh Completions](zsh_completions.md) for details.
## Fish completions
Cobra supports native Fish completions generated from the root `cobra.Command`. You can use the `command.GenFishCompletion()` or `command.GenFishCompletionFile()` functions. You must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra will provide the description automatically based on usage information. You can choose to make this option configurable by your users.
```
# With descriptions
$ helm s[tab]
search (search for a keyword in charts) show (show information of a chart) status (displays the status of the named release)
# Without descriptions
$ helm s[tab]
search show status
```
*Note*: Because of backwards-compatibility requirements, we were forced to have a different API to disable completion descriptions between `Zsh` and `Fish`.
### Limitations
* Custom completions implemented in Bash scripting (legacy) are not supported and will be ignored for `fish` (including the use of the `BashCompCustom` flag annotation).
* You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`).
* The function `MarkFlagCustom()` is not supported and will be ignored for `fish`.
* You should instead use `RegisterFlagCompletionFunc()`.
* The following flag completion annotations are not supported and will be ignored for `fish`:
* `BashCompFilenameExt` (filtering by file extension)
* `BashCompSubdirsInDir` (filtering by directory)
* The functions corresponding to the above annotations are consequently not supported and will be ignored for `fish`:
* `MarkFlagFilename()` and `MarkPersistentFlagFilename()` (filtering by file extension)
* `MarkFlagDirname()` and `MarkPersistentFlagDirname()` (filtering by directory)
* Similarly, the following completion directives are not supported and will be ignored for `fish`:
* `ShellCompDirectiveFilterFileExt` (filtering by file extension)
* `ShellCompDirectiveFilterDirs` (filtering by directory)

## Install
```console
go get github.com/spf13/viper
```
## What is Viper?
Viper is a complete configuration solution for Go applications including 12-Factor apps. It is designed
to work within an application, and can handle all types of configuration needs
and formats. It supports:
* setting defaults
* reading from JSON, TOML, YAML, HCL, envfile and Java properties config files
* live watching and re-reading of config files (optional)
* reading from environment variables
* reading from remote config systems (etcd or Consul), and watching changes
* reading from command line flags
* reading from buffer
* setting explicit values
Viper can be thought of as a registry for all of your applications configuration needs.
## Why Viper?
When building a modern application, you don’t want to worry about
configuration file formats; you want to focus on building awesome software.
Viper is here to help with that.
Viper does the following for you:
1. Find, load, and unmarshal a configuration file in JSON, TOML, YAML, HCL, INI, envfile or Java properties formats.
2. Provide a mechanism to set default values for your different configuration options.
3. Provide a mechanism to set override values for options specified through command line flags.
4. Provide an alias system to easily rename parameters without breaking existing code.
5. Make it easy to tell the difference between when a user has provided a command line or config file which is the same as the default.
Viper uses the following precedence order. Each item takes precedence over the item below it:
* explicit call to `Set`
* flag
* env
* config
* key/value store
* default
**Important:** Viper configuration keys are case insensitive.
There are ongoing discussions about making that optional.
## Putting Values into Viper
### Establishing Defaults
A good configuration system will support default values. A default value is not
required for a key, but it’s useful in the event that a key hasn't been set via
config file, environment variable, remote configuration or flag.
Examples:
```go
viper.SetDefault("ContentDir", "content")
viper.SetDefault("LayoutDir", "layouts")
viper.SetDefault("Taxonomies", map[string]string{"tag": "tags", "category": "categories"})
```
### Reading Config Files
Viper requires minimal configuration so it knows where to look for config files.
Viper supports JSON, TOML, YAML, HCL, INI, envfile and Java Properties files. Viper can search multiple paths, but
currently a single Viper instance only supports a single configuration file.
Viper does not default to any configuration search paths leaving defaults decision
to an application.
Here is an example of how to use Viper to search for and read a configuration file.
None of the specific paths are required, but at least one path should be provided
where a configuration file is expected.
```go
viper.SetConfigName("config") // name of config file (without extension)
viper.SetConfigType("yaml") // REQUIRED if the config file does not have the extension in the name
viper.AddConfigPath("/etc/appname/") // path to look for the config file in
viper.AddConfigPath("$HOME/.appname") // call multiple times to add many search paths
viper.AddConfigPath(".") // optionally look for config in the working directory
err := viper.ReadInConfig() // Find and read the config file
if err != nil { // Handle errors reading the config file
panic(fmt.Errorf("Fatal error config file: %s \n", err))
}
```
You can handle the specific case where no config file is found like this:
```go
if err := viper.ReadInConfig(); err != nil {
if _, ok := err.(viper.ConfigFileNotFoundError); ok {
// Config file not found; ignore error if desired
} else {
// Config file was found but another error was produced
}
}
// Config file found and successfully parsed
```
*NOTE [since 1.6]:* You can also have a file without an extension and specify the format programmaticaly. For those configuration files that lie in the home of the user without any extension like `.bashrc`
### Writing Config Files
Reading from config files is useful, but at times you want to store all modifications made at run time.
For that, a bunch of commands are available, each with its own purpose:
* WriteConfig - writes the current viper configuration to the predefined path, if exists. Errors if no predefined path. Will overwrite the current config file, if it exists.
* SafeWriteConfig - writes the current viper configuration to the predefined path. Errors if no predefined path. Will not overwrite the current config file, if it exists.
* WriteConfigAs - writes the current viper configuration to the given filepath. Will overwrite the given file, if it exists.
* SafeWriteConfigAs - writes the current viper configuration to the given filepath. Will not overwrite the given file, if it exists.
As a rule of the thumb, everything marked with safe won't overwrite any file, but just create if not existent, whilst the default behavior is to create or truncate.
A small examples section:
```go
viper.WriteConfig() // writes current config to predefined path set by 'viper.AddConfigPath()' and 'viper.SetConfigName'
viper.SafeWriteConfig()
viper.WriteConfigAs("/path/to/my/.config")
viper.SafeWriteConfigAs("/path/to/my/.config") // will error since it has already been written
viper.SafeWriteConfigAs("/path/to/my/.other_config")
```
### Watching and re-reading config files
Viper supports the ability to have your application live read a config file while running.
Gone are the days of needing to restart a server to have a config take effect,
viper powered applications can read an update to a config file while running and
not miss a beat.
Simply tell the viper instance to watchConfig.
Optionally you can provide a function for Viper to run each time a change occurs.
**Make sure you add all of the configPaths prior to calling `WatchConfig()`**
```go
viper.WatchConfig()
viper.OnConfigChange(func(e fsnotify.Event) {
fmt.Println("Config file changed:", e.Name)
})
```
### Reading Config from io.Reader
Viper predefines many configuration sources such as files, environment
variables, flags, and remote K/V store, but you are not bound to them. You can
also implement your own required configuration source and feed it to viper.
```go
viper.SetConfigType("yaml") // or viper.SetConfigType("YAML")
// any approach to require this configuration into your program.
var yamlExample = []byte(`
Hacker: true
name: steve
hobbies:
- skateboarding
- snowboarding
- go
clothing:
jacket: leather
trousers: denim
age: 35
eyes : brown
beard: true
`)
viper.ReadConfig(bytes.NewBuffer(yamlExample))
viper.Get("name") // this would be "steve"
```
### Setting Overrides
These could be from a command line flag, or from your own application logic.
```go
viper.Set("Verbose", true)
viper.Set("LogFile", LogFile)
```
### Registering and Using Aliases
Aliases permit a single value to be referenced by multiple keys
```go
viper.RegisterAlias("loud", "Verbose")
viper.Set("verbose", true) // same result as next line
viper.Set("loud", true) // same result as prior line
viper.GetBool("loud") // true
viper.GetBool("verbose") // true
```
### Working with Environment Variables
Viper has full support for environment variables. This enables 12 factor
applications out of the box. There are five methods that exist to aid working
with ENV:
* `AutomaticEnv()`
* `BindEnv(string...) : error`
* `SetEnvPrefix(string)`
* `SetEnvKeyReplacer(string...) *strings.Replacer`
* `AllowEmptyEnv(bool)`
_When working with ENV variables, it’s important to recognize that Viper
treats ENV variables as case sensitive._
Viper provides a mechanism to try to ensure that ENV variables are unique. By
using `SetEnvPrefix`, you can tell Viper to use a prefix while reading from
the environment variables. Both `BindEnv` and `AutomaticEnv` will use this
prefix.
`BindEnv` takes one or two parameters. The first parameter is the key name, the
second is the name of the environment variable. The name of the environment
variable is case sensitive. If the ENV variable name is not provided, then
Viper will automatically assume that the ENV variable matches the following format: prefix + "_" + the key name in ALL CAPS. When you explicitly provide the ENV variable name (the second parameter),
it **does not** automatically add the prefix. For example if the second parameter is "id",
Viper will look for the ENV variable "ID".
One important thing to recognize when working with ENV variables is that the
value will be read each time it is accessed. Viper does not fix the value when
the `BindEnv` is called.
`AutomaticEnv` is a powerful helper especially when combined with
`SetEnvPrefix`. When called, Viper will check for an environment variable any
time a `viper.Get` request is made. It will apply the following rules. It will
check for a environment variable with a name matching the key uppercased and
prefixed with the `EnvPrefix` if set.
`SetEnvKeyReplacer` allows you to use a `strings.Replacer` object to rewrite Env
keys to an extent. This is useful if you want to use `-` or something in your
`Get()` calls, but want your environmental variables to use `_` delimiters. An
example of using it can be found in `viper_test.go`.
Alternatively, you can use `EnvKeyReplacer` with `NewWithOptions` factory function.
Unlike `SetEnvKeyReplacer`, it accepts a `StringReplacer` interface allowing you to write custom string replacing logic.
By default empty environment variables are considered unset and will fall back to
the next configuration source. To treat empty environment variables as set, use
the `AllowEmptyEnv` method.
#### Env example
```go
SetEnvPrefix("spf") // will be uppercased automatically
BindEnv("id")
os.Setenv("SPF_ID", "13") // typically done outside of the app
id := Get("id") // 13
```
### Working with Flags
Viper has the ability to bind to flags. Specifically, Viper supports `Pflags`
as used in the [Cobra](https://github.com/spf13/cobra) library.
Like `BindEnv`, the value is not set when the binding method is called, but when
it is accessed. This means you can bind as early as you want, even in an
`init()` function.
For individual flags, the `BindPFlag()` method provides this functionality.
Example:
```go
serverCmd.Flags().Int("port", 1138, "Port to run Application server on")
viper.BindPFlag("port", serverCmd.Flags().Lookup("port"))
```
You can also bind an existing set of pflags (pflag.FlagSet):
Example:
```go
pflag.Int("flagname", 1234, "help message for flagname")
pflag.Parse()
viper.BindPFlags(pflag.CommandLine)
i := viper.GetInt("flagname") // retrieve values from viper instead of pflag
```
The use of [pflag](https://github.com/spf13/pflag/) in Viper does not preclude
the use of other packages that use the [flag](https://golang.org/pkg/flag/)
package from the standard library. The pflag package can handle the flags
defined for the flag package by importing these flags. This is accomplished
by a calling a convenience function provided by the pflag package called
AddGoFlagSet().
Example:
```go
package main
import (
"flag"
"github.com/spf13/pflag"
)
func main() {
// using standard library "flag" package
flag.Int("flagname", 1234, "help message for flagname")
pflag.CommandLine.AddGoFlagSet(flag.CommandLine)
pflag.Parse()
viper.BindPFlags(pflag.CommandLine)
i := viper.GetInt("flagname") // retrieve value from viper
...
}
```
#### Flag interfaces
Viper provides two Go interfaces to bind other flag systems if you don’t use `Pflags`.
`FlagValue` represents a single flag. This is a very simple example on how to implement this interface:
```go
type myFlag struct {}
func (f myFlag) HasChanged() bool { return false }
func (f myFlag) Name() string { return "my-flag-name" }
func (f myFlag) ValueString() string { return "my-flag-value" }
func (f myFlag) ValueType() string { return "string" }
```
Once your flag implements this interface, you can simply tell Viper to bind it:
```go
viper.BindFlagValue("my-flag-name", myFlag{})
```
`FlagValueSet` represents a group of flags. This is a very simple example on how to implement this interface:
```go
type myFlagSet struct {
flags []myFlag
}
func (f myFlagSet) VisitAll(fn func(FlagValue)) {
for _, flag := range flags {
fn(flag)
}
}
```
Once your flag set implements this interface, you can simply tell Viper to bind it:
```go
fSet := myFlagSet{
flags: []myFlag{myFlag{}, myFlag{}},
}
viper.BindFlagValues("my-flags", fSet)
```
### Remote Key/Value Store Support
To enable remote support in Viper, do a blank import of the `viper/remote`
package:
`import _ "github.com/spf13/viper/remote"`
Viper will read a config string (as JSON, TOML, YAML, HCL or envfile) retrieved from a path
in a Key/Value store such as etcd or Consul. These values take precedence over
default values, but are overridden by configuration values retrieved from disk,
flags, or environment variables.
Viper uses [crypt](https://github.com/bketelsen/crypt) to retrieve
configuration from the K/V store, which means that you can store your
configuration values encrypted and have them automatically decrypted if you have
the correct gpg keyring. Encryption is optional.
You can use remote configuration in conjunction with local configuration, or
independently of it.
`crypt` has a command-line helper that you can use to put configurations in your
K/V store. `crypt` defaults to etcd on http://127.0.0.1:4001.
```bash
$ go get github.com/bketelsen/crypt/bin/crypt
$ crypt set -plaintext /config/hugo.json /Users/hugo/settings/config.json
```
Confirm that your value was set:
```bash
$ crypt get -plaintext /config/hugo.json
```
See the `crypt` documentation for examples of how to set encrypted values, or
how to use Consul.
### Remote Key/Value Store Example - Unencrypted
#### etcd
```go
viper.AddRemoteProvider("etcd", "http://127.0.0.1:4001","/config/hugo.json")
viper.SetConfigType("json") // because there is no file extension in a stream of bytes, supported extensions are "json", "toml", "yaml", "yml", "properties", "props", "prop", "env", "dotenv"
err := viper.ReadRemoteConfig()
```
#### Consul
You need to set a key to Consul key/value storage with JSON value containing your desired config.
For example, create a Consul key/value store key `MY_CONSUL_KEY` with value:
```json
{
"port": 8080,
"hostname": "myhostname.com"
}
```
```go
viper.AddRemoteProvider("consul", "localhost:8500", "MY_CONSUL_KEY")
viper.SetConfigType("json") // Need to explicitly set this to json
err := viper.ReadRemoteConfig()
fmt.Println(viper.Get("port")) // 8080
fmt.Println(viper.Get("hostname")) // myhostname.com
```
#### Firestore
```go
viper.AddRemoteProvider("firestore", "google-cloud-project-id", "collection/document")
viper.SetConfigType("json") // Config's format: "json", "toml", "yaml", "yml"
err := viper.ReadRemoteConfig()
```
Of course, you're allowed to use `SecureRemoteProvider` also
### Remote Key/Value Store Example - Encrypted
```go
viper.AddSecureRemoteProvider("etcd","http://127.0.0.1:4001","/config/hugo.json","/etc/secrets/mykeyring.gpg")
viper.SetConfigType("json") // because there is no file extension in a stream of bytes, supported extensions are "json", "toml", "yaml", "yml", "properties", "props", "prop", "env", "dotenv"
err := viper.ReadRemoteConfig()
```
### Watching Changes in etcd - Unencrypted
```go
// alternatively, you can create a new viper instance.
var runtime_viper = viper.New()
runtime_viper.AddRemoteProvider("etcd", "http://127.0.0.1:4001", "/config/hugo.yml")
runtime_viper.SetConfigType("yaml") // because there is no file extension in a stream of bytes, supported extensions are "json", "toml", "yaml", "yml", "properties", "props", "prop", "env", "dotenv"
// read from remote config the first time.
err := runtime_viper.ReadRemoteConfig()
// unmarshal config
runtime_viper.Unmarshal(&runtime_conf)
// open a goroutine to watch remote changes forever
go func(){
for {
time.Sleep(time.Second * 5) // delay after each request
// currently, only tested with etcd support
err := runtime_viper.WatchRemoteConfig()
if err != nil {
log.Errorf("unable to read remote config: %v", err)
continue
}
// unmarshal new config into our runtime config struct. you can also use channel
// to implement a signal to notify the system of the changes
runtime_viper.Unmarshal(&runtime_conf)
}
}()
```
## Getting Values From Viper
In Viper, there are a few ways to get a value depending on the value’s type.
The following functions and methods exist:
* `Get(key string) : interface{}`
* `GetBool(key string) : bool`
* `GetFloat64(key string) : float64`
* `GetInt(key string) : int`
* `GetIntSlice(key string) : []int`
* `GetString(key string) : string`
* `GetStringMap(key string) : map[string]interface{}`
* `GetStringMapString(key string) : map[string]string`
* `GetStringSlice(key string) : []string`
* `GetTime(key string) : time.Time`
* `GetDuration(key string) : time.Duration`
* `IsSet(key string) : bool`
* `AllSettings() : map[string]interface{}`
One important thing to recognize is that each Get function will return a zero
value if it’s not found. To check if a given key exists, the `IsSet()` method
has been provided.
Example:
```go
viper.GetString("logfile") // case-insensitive Setting & Getting
if viper.GetBool("verbose") {
fmt.Println("verbose enabled")
}
```
### Accessing nested keys
The accessor methods also accept formatted paths to deeply nested keys. For
example, if the following JSON file is loaded:
```json
{
"host": {
"address": "localhost",
"port": 5799
},
"datastore": {
"metric": {
"host": "127.0.0.1",
"port": 3099
},
"warehouse": {
"host": "198.0.0.1",
"port": 2112
}
}
}
```
Viper can access a nested field by passing a `.` delimited path of keys:
```go
GetString("datastore.metric.host") // (returns "127.0.0.1")
```
This obeys the precedence rules established above; the search for the path
will cascade through the remaining configuration registries until found.
For example, given this configuration file, both `datastore.metric.host` and
`datastore.metric.port` are already defined (and may be overridden). If in addition
`datastore.metric.protocol` was defined in the defaults, Viper would also find it.
However, if `datastore.metric` was overridden (by a flag, an environment variable,
the `Set()` method, …) with an immediate value, then all sub-keys of
`datastore.metric` become undefined, they are “shadowed” by the higher-priority
configuration level.
Lastly, if there exists a key that matches the delimited key path, its value
will be returned instead. E.g.
```json
{
"datastore.metric.host": "0.0.0.0",
"host": {
"address": "localhost",
"port": 5799
},
"datastore": {
"metric": {
"host": "127.0.0.1",
"port": 3099
},
"warehouse": {
"host": "198.0.0.1",
"port": 2112
}
}
}
GetString("datastore.metric.host") // returns "0.0.0.0"
```
### Extract sub-tree
Extract sub-tree from Viper.
For example, `viper` represents:
```json
app:
cache1:
max-items: 100
item-size: 64
cache2:
max-items: 200
item-size: 80
```
After executing:
```go
subv := viper.Sub("app.cache1")
```
`subv` represents:
```json
max-items: 100
item-size: 64
```
Suppose we have:
```go
func NewCache(cfg *Viper) *Cache {...}
```
which creates a cache based on config information formatted as `subv`.
Now it’s easy to create these 2 caches separately as:
```go
cfg1 := viper.Sub("app.cache1")
cache1 := NewCache(cfg1)
cfg2 := viper.Sub("app.cache2")
cache2 := NewCache(cfg2)
```
### Unmarshaling
You also have the option of Unmarshaling all or a specific value to a struct, map,
etc.
There are two methods to do this:
* `Unmarshal(rawVal interface{}) : error`
* `UnmarshalKey(key string, rawVal interface{}) : error`
Example:
```go
type config struct {
Port int
Name string
PathMap string `mapstructure:"path_map"`
}
var C config
err := viper.Unmarshal(&C)
if err != nil {
t.Fatalf("unable to decode into struct, %v", err)
}
```
If you want to unmarshal configuration where the keys themselves contain dot (the default key delimiter),
you have to change the delimiter:
```go
v := viper.NewWithOptions(viper.KeyDelimiter("::"))
v.SetDefault("chart::values", map[string]interface{}{
"ingress": map[string]interface{}{
"annotations": map[string]interface{}{
"traefik.frontend.rule.type": "PathPrefix",
"traefik.ingress.kubernetes.io/ssl-redirect": "true",
},
},
})
type config struct {
Chart struct{
Values map[string]interface{}
}
}
var C config
v.Unmarshal(&C)
```
Viper also supports unmarshaling into embedded structs:
```go
/*
Example config:
module:
enabled: true
token: 89h3f98hbwf987h3f98wenf89ehf
*/
type config struct {
Module struct {
Enabled bool
moduleConfig `mapstructure:",squash"`
}
}
// moduleConfig could be in a module specific package
type moduleConfig struct {
Token string
}
var C config
err := viper.Unmarshal(&C)
if err != nil {
t.Fatalf("unable to decode into struct, %v", err)
}
```
Viper uses [github.com/mitchellh/mapstructure](https://github.com/mitchellh/mapstructure) under the hood for unmarshaling values which uses `mapstructure` tags by default.
### Marshalling to string
You may need to marshal all the settings held in viper into a string rather than write them to a file.
You can use your favorite format's marshaller with the config returned by `AllSettings()`.
```go
import (
yaml "gopkg.in/yaml.v2"
// ...
)
func yamlStringSettings() string {
c := viper.AllSettings()
bs, err := yaml.Marshal(c)
if err != nil {
log.Fatalf("unable to marshal config to YAML: %v", err)
}
return string(bs)
}
```
## Viper or Vipers?
Viper comes ready to use out of the box. There is no configuration or
initialization needed to begin using Viper. Since most applications will want
to use a single central repository for their configuration, the viper package
provides this. It is similar to a singleton.
In all of the examples above, they demonstrate using viper in its singleton
style approach.
### Working with multiple vipers
You can also create many different vipers for use in your application. Each will
have its own unique set of configurations and values. Each can read from a
different config file, key value store, etc. All of the functions that viper
package supports are mirrored as methods on a viper.
Example:
```go
x := viper.New()
y := viper.New()
x.SetDefault("ContentDir", "content")
y.SetDefault("ContentDir", "foobar")
//...
```
When working with multiple vipers, it is up to the user to keep track of the
different vipers.
## Q & A
Q: Why is it called “Viper”?
A: Viper is designed to be a [companion](http://en.wikipedia.org/wiki/Viper_(G.I._Joe))
to [Cobra](https://github.com/spf13/cobra). While both can operate completely
independently, together they make a powerful pair to handle much of your
application foundation needs.
Q: Why is it called “Cobra”?
A: Is there a better name for a [commander](http://en.wikipedia.org/wiki/Cobra_Commander)?

=================
Seamless printing to the terminal (stdout) and logging to a io.Writer
(file) that’s as easy to use as fmt.Println.
Graphic by [JonnyEtc](http://jonnyetc.deviantart.com/art/And-That-s-Why-You-Always-Leave-a-Note-315311422)
JWW is primarily a wrapper around the excellent standard log library. It
provides a few advantages over using the standard log library alone.
1. Ready to go out of the box.
2. One library for both printing to the terminal and logging (to files).
3. Really easy to log to either a temp file or a file you specify.
I really wanted a very straightforward library that could seamlessly do
the following things.
1. Replace all the println, printf, etc statements thoughout my code with
something more useful
2. Allow the user to easily control what levels are printed to stdout
3. Allow the user to easily control what levels are logged
4. Provide an easy mechanism (like fmt.Println) to print info to the user
which can be easily logged as well
5. Due to 2 & 3 provide easy verbose mode for output and logs
6. Not have any unnecessary initialization cruft. Just use it.
# Usage
## Step 1. Use it
Put calls throughout your source based on type of feedback.
No initialization or setup needs to happen. Just start calling things.
Available Loggers are:
* TRACE
* DEBUG
* INFO
* WARN
* ERROR
* CRITICAL
* FATAL
These each are loggers based on the log standard library and follow the
standard usage. Eg.
```go
import (
jww "github.com/spf13/jwalterweatherman"
)
...
if err != nil {
// This is a pretty serious error and the user should know about
// it. It will be printed to the terminal as well as logged under the
// default thresholds.
jww.ERROR.Println(err)
}
if err2 != nil {
// This error isn’t going to materially change the behavior of the
// application, but it’s something that may not be what the user
// expects. Under the default thresholds, Warn will be logged, but
// not printed to the terminal.
jww.WARN.Println(err2)
}
// Information that’s relevant to what’s happening, but not very
// important for the user. Under the default thresholds this will be
// discarded.
jww.INFO.Printf("information %q", response)
```
NOTE: You can also use the library in a non-global setting by creating an instance of a Notebook:
```go
notepad = jww.NewNotepad(jww.LevelInfo, jww.LevelTrace, os.Stdout, ioutil.Discard, "", log.Ldate|log.Ltime)
notepad.WARN.Println("Some warning"")
```
_Why 7 levels?_
Maybe you think that 7 levels are too much for any application... and you
are probably correct. Just because there are seven levels doesn’t mean
that you should be using all 7 levels. Pick the right set for your needs.
Remember they only have to mean something to your project.
## Step 2. Optionally configure JWW
Under the default thresholds :
* Debug, Trace & Info goto /dev/null
* Warn and above is logged (when a log file/io.Writer is provided)
* Error and above is printed to the terminal (stdout)
### Changing the thresholds
The threshold can be changed at any time, but will only affect calls that
execute after the change was made.
This is very useful if your application has a verbose mode. Of course you
can decide what verbose means to you or even have multiple levels of
verbosity.
```go
import (
jww "github.com/spf13/jwalterweatherman"
)
if Verbose {
jww.SetLogThreshold(jww.LevelTrace)
jww.SetStdoutThreshold(jww.LevelInfo)
}
```
Note that JWW's own internal output uses log levels as well, so set the log
level before making any other calls if you want to see what it's up to.
### Setting a log file
JWW can log to any `io.Writer`:
```go
jww.SetLogOutput(customWriter)
```
# More information
This is an early release. I’ve been using it for a while and this is the
third interface I’ve tried. I like this one pretty well, but no guarantees
that it won’t change a bit.
I wrote this for use in [hugo](https://gohugo.io). If you are looking
for a static website engine that’s super fast please checkout Hugo.

A FileSystem Abstraction System for Go
[](https://travis-ci.org/spf13/afero) [](https://ci.appveyor.com/project/spf13/afero) [](https://godoc.org/github.com/spf13/afero) [](https://gitter.im/spf13/afero?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
# Overview
Afero is an filesystem framework providing a simple, uniform and universal API
interacting with any filesystem, as an abstraction layer providing interfaces,
types and methods. Afero has an exceptionally clean interface and simple design
without needless constructors or initialization methods.
Afero is also a library providing a base set of interoperable backend
filesystems that make it easy to work with afero while retaining all the power
and benefit of the os and ioutil packages.
Afero provides significant improvements over using the os package alone, most
notably the ability to create mock and testing filesystems without relying on the disk.
It is suitable for use in a any situation where you would consider using the OS
package as it provides an additional abstraction that makes it easy to use a
memory backed file system during testing. It also adds support for the http
filesystem for full interoperability.
## Afero Features
* A single consistent API for accessing a variety of filesystems
* Interoperation between a variety of file system types
* A set of interfaces to encourage and enforce interoperability between backends
* An atomic cross platform memory backed file system
* Support for compositional (union) file systems by combining multiple file systems acting as one
* Specialized backends which modify existing filesystems (Read Only, Regexp filtered)
* A set of utility functions ported from io, ioutil & hugo to be afero aware
# Using Afero
Afero is easy to use and easier to adopt.
A few different ways you could use Afero:
* Use the interfaces alone to define you own file system.
* Wrap for the OS packages.
* Define different filesystems for different parts of your application.
* Use Afero for mock filesystems while testing
## Step 1: Install Afero
First use go get to install the latest version of the library.
$ go get github.com/spf13/afero
Next include Afero in your application.
```go
import "github.com/spf13/afero"
```
## Step 2: Declare a backend
First define a package variable and set it to a pointer to a filesystem.
```go
var AppFs = afero.NewMemMapFs()
or
var AppFs = afero.NewOsFs()
```
It is important to note that if you repeat the composite literal you
will be using a completely new and isolated filesystem. In the case of
OsFs it will still use the same underlying filesystem but will reduce
the ability to drop in other filesystems as desired.
## Step 3: Use it like you would the OS package
Throughout your application use any function and method like you normally
would.
So if my application before had:
```go
os.Open('/tmp/foo')
```
We would replace it with:
```go
AppFs.Open('/tmp/foo')
```
`AppFs` being the variable we defined above.
## List of all available functions
File System Methods Available:
```go
Chmod(name string, mode os.FileMode) : error
Chtimes(name string, atime time.Time, mtime time.Time) : error
Create(name string) : File, error
Mkdir(name string, perm os.FileMode) : error
MkdirAll(path string, perm os.FileMode) : error
Name() : string
Open(name string) : File, error
OpenFile(name string, flag int, perm os.FileMode) : File, error
Remove(name string) : error
RemoveAll(path string) : error
Rename(oldname, newname string) : error
Stat(name string) : os.FileInfo, error
```
File Interfaces and Methods Available:
```go
io.Closer
io.Reader
io.ReaderAt
io.Seeker
io.Writer
io.WriterAt
Name() : string
Readdir(count int) : []os.FileInfo, error
Readdirnames(n int) : []string, error
Stat() : os.FileInfo, error
Sync() : error
Truncate(size int64) : error
WriteString(s string) : ret int, err error
```
In some applications it may make sense to define a new package that
simply exports the file system variable for easy access from anywhere.
## Using Afero's utility functions
Afero provides a set of functions to make it easier to use the underlying file systems.
These functions have been primarily ported from io & ioutil with some developed for Hugo.
The afero utilities support all afero compatible backends.
The list of utilities includes:
```go
DirExists(path string) (bool, error)
Exists(path string) (bool, error)
FileContainsBytes(filename string, subslice []byte) (bool, error)
GetTempDir(subPath string) string
IsDir(path string) (bool, error)
IsEmpty(path string) (bool, error)
ReadDir(dirname string) ([]os.FileInfo, error)
ReadFile(filename string) ([]byte, error)
SafeWriteReader(path string, r io.Reader) (err error)
TempDir(dir, prefix string) (name string, err error)
TempFile(dir, prefix string) (f File, err error)
Walk(root string, walkFn filepath.WalkFunc) error
WriteFile(filename string, data []byte, perm os.FileMode) error
WriteReader(path string, r io.Reader) (err error)
```
For a complete list see [Afero's GoDoc](https://godoc.org/github.com/spf13/afero)
They are available under two different approaches to use. You can either call
them directly where the first parameter of each function will be the file
system, or you can declare a new `Afero`, a custom type used to bind these
functions as methods to a given filesystem.
### Calling utilities directly
```go
fs := new(afero.MemMapFs)
f, err := afero.TempFile(fs,"", "ioutil-test")
```
### Calling via Afero
```go
fs := afero.NewMemMapFs()
afs := &afero.Afero{Fs: fs}
f, err := afs.TempFile("", "ioutil-test")
```
## Using Afero for Testing
There is a large benefit to using a mock filesystem for testing. It has a
completely blank state every time it is initialized and can be easily
reproducible regardless of OS. You could create files to your heart’s content
and the file access would be fast while also saving you from all the annoying
issues with deleting temporary files, Windows file locking, etc. The MemMapFs
backend is perfect for testing.
* Much faster than performing I/O operations on disk
* Avoid security issues and permissions
* Far more control. 'rm -rf /' with confidence
* Test setup is far more easier to do
* No test cleanup needed
One way to accomplish this is to define a variable as mentioned above.
In your application this will be set to afero.NewOsFs() during testing you
can set it to afero.NewMemMapFs().
It wouldn't be uncommon to have each test initialize a blank slate memory
backend. To do this I would define my `appFS = afero.NewOsFs()` somewhere
appropriate in my application code. This approach ensures that Tests are order
independent, with no test relying on the state left by an earlier test.
Then in my tests I would initialize a new MemMapFs for each test:
```go
func TestExist(t *testing.T) {
appFS := afero.NewMemMapFs()
// create test files and directories
appFS.MkdirAll("src/a", 0755)
afero.WriteFile(appFS, "src/a/b", []byte("file b"), 0644)
afero.WriteFile(appFS, "src/c", []byte("file c"), 0644)
name := "src/c"
_, err := appFS.Stat(name)
if os.IsNotExist(err) {
t.Errorf("file \"%s\" does not exist.\n", name)
}
}
```
# Available Backends
## Operating System Native
### OsFs
The first is simply a wrapper around the native OS calls. This makes it
very easy to use as all of the calls are the same as the existing OS
calls. It also makes it trivial to have your code use the OS during
operation and a mock filesystem during testing or as needed.
```go
appfs := afero.NewOsFs()
appfs.MkdirAll("src/a", 0755))
```
## Memory Backed Storage
### MemMapFs
Afero also provides a fully atomic memory backed filesystem perfect for use in
mocking and to speed up unnecessary disk io when persistence isn’t
necessary. It is fully concurrent and will work within go routines
safely.
```go
mm := afero.NewMemMapFs()
mm.MkdirAll("src/a", 0755))
```
#### InMemoryFile
As part of MemMapFs, Afero also provides an atomic, fully concurrent memory
backed file implementation. This can be used in other memory backed file
systems with ease. Plans are to add a radix tree memory stored file
system using InMemoryFile.
## Network Interfaces
### SftpFs
Afero has experimental support for secure file transfer protocol (sftp). Which can
be used to perform file operations over a encrypted channel.
## Filtering Backends
### BasePathFs
The BasePathFs restricts all operations to a given path within an Fs.
The given file name to the operations on this Fs will be prepended with
the base path before calling the source Fs.
```go
bp := afero.NewBasePathFs(afero.NewOsFs(), "/base/path")
```
### ReadOnlyFs
A thin wrapper around the source Fs providing a read only view.
```go
fs := afero.NewReadOnlyFs(afero.NewOsFs())
_, err := fs.Create("/file.txt")
// err = syscall.EPERM
```
# RegexpFs
A filtered view on file names, any file NOT matching
the passed regexp will be treated as non-existing.
Files not matching the regexp provided will not be created.
Directories are not filtered.
```go
fs := afero.NewRegexpFs(afero.NewMemMapFs(), regexp.MustCompile(`\.txt$`))
_, err := fs.Create("/file.html")
// err = syscall.ENOENT
```
### HttpFs
Afero provides an http compatible backend which can wrap any of the existing
backends.
The Http package requires a slightly specific version of Open which
returns an http.File type.
Afero provides an httpFs file system which satisfies this requirement.
Any Afero FileSystem can be used as an httpFs.
```go
httpFs := afero.NewHttpFs(<ExistingFS>)
fileserver := http.FileServer(httpFs.Dir(<PATH>)))
http.Handle("/", fileserver)
```
## Composite Backends
Afero provides the ability have two filesystems (or more) act as a single
file system.
### CacheOnReadFs
The CacheOnReadFs will lazily make copies of any accessed files from the base
layer into the overlay. Subsequent reads will be pulled from the overlay
directly permitting the request is within the cache duration of when it was
created in the overlay.
If the base filesystem is writeable, any changes to files will be
done first to the base, then to the overlay layer. Write calls to open file
handles like `Write()` or `Truncate()` to the overlay first.
To writing files to the overlay only, you can use the overlay Fs directly (not
via the union Fs).
Cache files in the layer for the given time.Duration, a cache duration of 0
means "forever" meaning the file will not be re-requested from the base ever.
A read-only base will make the overlay also read-only but still copy files
from the base to the overlay when they're not present (or outdated) in the
caching layer.
```go
base := afero.NewOsFs()
layer := afero.NewMemMapFs()
ufs := afero.NewCacheOnReadFs(base, layer, 100 * time.Second)
```
### CopyOnWriteFs()
The CopyOnWriteFs is a read only base file system with a potentially
writeable layer on top.
Read operations will first look in the overlay and if not found there, will
serve the file from the base.
Changes to the file system will only be made in the overlay.
Any attempt to modify a file found only in the base will copy the file to the
overlay layer before modification (including opening a file with a writable
handle).
Removing and Renaming files present only in the base layer is not currently
permitted. If a file is present in the base layer and the overlay, only the
overlay will be removed/renamed.
```go
base := afero.NewOsFs()
roBase := afero.NewReadOnlyFs(base)
ufs := afero.NewCopyOnWriteFs(roBase, afero.NewMemMapFs())
fh, _ = ufs.Create("/home/test/file2.txt")
fh.WriteString("This is a test")
fh.Close()
```
In this example all write operations will only occur in memory (MemMapFs)
leaving the base filesystem (OsFs) untouched.
## Desired/possible backends
The following is a short list of possible backends we hope someone will
implement:
* SSH
* ZIP
* TAR
* S3
# About the project
## What's in the name
Afero comes from the latin roots Ad-Facere.
**"Ad"** is a prefix meaning "to".
**"Facere"** is a form of the root "faciō" making "make or do".
The literal meaning of afero is "to make" or "to do" which seems very fitting
for a library that allows one to make files and directories and do things with them.
The English word that shares the same roots as Afero is "affair". Affair shares
the same concept but as a noun it means "something that is made or done" or "an
object of a particular type".
It's also nice that unlike some of my other libraries (hugo, cobra, viper) it
Googles very well.
