Easy and safe casting from one type to another in Go
Dont Panic! ... Cast
## What is Cast?
Cast is a library to convert between different go types in a consistent and easy way.
Cast provides simple functions to easily convert a number to a string, an
interface into a bool, etc. Cast does this intelligently when an obvious
conversion is possible. It doesnt make any attempts to guess what you meant,
for example you can only convert a string to an int when it is a string
representation of an int such as “8”. Cast was developed for use in
[Hugo](http://hugo.spf13.com), a website engine which uses YAML, TOML or JSON
for meta data.
## Why use Cast?
When working with dynamic data in Go you often need to cast or convert the data
from one type into another. Cast goes beyond just using type assertion (though
it uses that when possible) to provide a very straightforward and convenient
library.
If you are working with interfaces to handle things like dynamic content
youll need an easy way to convert an interface into a given type. This
is the library for you.
If you are taking in data from YAML, TOML or JSON or other formats which lack
full types, then Cast is the library for you.
## Usage
Cast provides a handful of To_____ methods. These methods will always return
the desired type. **If input is provided that will not convert to that type, the
0 or nil value for that type will be returned**.
Cast also provides identical methods To_____E. These return the same result as
the To_____ methods, plus an additional error which tells you if it successfully
converted. Using these methods you can tell the difference between when the
input matched the zero value or when the conversion failed and the zero value
was returned.
The following examples are merely a sample of what is available. Please review
the code for a complete set.
### Example ToString:
cast.ToString("mayonegg") // "mayonegg"
cast.ToString(8) // "8"
cast.ToString(8.31) // "8.31"
cast.ToString([]byte("one time")) // "one time"
cast.ToString(nil) // ""
var foo interface{} = "one more time"
cast.ToString(foo) // "one more time"
### Example ToInt:
cast.ToInt(8) // 8
cast.ToInt(8.31) // 8
cast.ToInt("8") // 8
cast.ToInt(true) // 1
cast.ToInt(false) // 0
var eight interface{} = 8
cast.ToInt(eight) // 8
cast.ToInt(nil) // 0

=================
Seamless printing to the terminal (stdout) and logging to a io.Writer
(file) thats as easy to use as fmt.Println.
![and_that__s_why_you_always_leave_a_note_by_jonnyetc-d57q7um](https://cloud.githubusercontent.com/assets/173412/11002937/ccd01654-847d-11e5-828e-12ebaf582eaf.jpg)
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 isnt going to materially change the behavior of the
// application, but its 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 thats relevant to whats 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 doesnt 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. Ive been using it for a while and this is the
third interface Ive tried. I like this one pretty well, but no guarantees
that it wont change a bit.
I wrote this for use in [hugo](https://gohugo.io). If you are looking
for a static website engine thats super fast please checkout Hugo.

**Go configuration with fangs!**
Many Go projects are built using Viper including:
* [Hugo](http://gohugo.io)
* [EMC RexRay](http://rexray.readthedocs.org/en/stable/)
* [Imgurs Incus](https://github.com/Imgur/incus)
* [Nanobox](https://github.com/nanobox-io/nanobox)/[Nanopack](https://github.com/nanopack)
* [Docker Notary](https://github.com/docker/Notary)
* [BloomApi](https://www.bloomapi.com/)
* [doctl](https://github.com/digitalocean/doctl)
* [Clairctl](https://github.com/jgsqware/clairctl)
* [Mercure](https://mercure.rocks)
## 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 dont 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 its 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, its 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 dont 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 values 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 its 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 its 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)?
