## Description
pflag is a drop-in replacement for Go's flag package, implementing
POSIX/GNU-style --flags.
pflag is compatible with the [GNU extensions to the POSIX recommendations
for command-line options][1]. For a more precise description, see the
"Command-line flag syntax" section below.
[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
pflag is available under the same style of BSD license as the Go language,
which can be found in the LICENSE file.
## Installation
pflag is available using the standard `go get` command.
Install by running:
go get github.com/spf13/pflag
Run tests by running:
go test github.com/spf13/pflag
## Usage
pflag is a drop-in replacement of Go's native flag package. If you import
pflag under the name "flag" then all code should continue to function
with no changes.
``` go
import flag "github.com/spf13/pflag"
```
There is one exception to this: if you directly instantiate the Flag struct
there is one more field "Shorthand" that you will need to set.
Most code never instantiates this struct directly, and instead uses
functions such as String(), BoolVar(), and Var(), and is therefore
unaffected.
Define flags using flag.String(), Bool(), Int(), etc.
This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
``` go
var ip *int = flag.Int("flagname", 1234, "help message for flagname")
```
If you like, you can bind the flag to a variable using the Var() functions.
``` go
var flagvar int
func init() {
flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
}
```
Or you can create custom flags that satisfy the Value interface (with
pointer receivers) and couple them to flag parsing by
``` go
flag.Var(&flagVal, "name", "help message for flagname")
```
For such flags, the default value is just the initial value of the variable.
After all flags are defined, call
``` go
flag.Parse()
```
to parse the command line into the defined flags.
Flags may then be used directly. If you're using the flags themselves,
they are all pointers; if you bind to variables, they're values.
``` go
fmt.Println("ip has value ", *ip)
fmt.Println("flagvar has value ", flagvar)
```
There are helper functions available to get the value stored in a Flag if you have a FlagSet but find
it difficult to keep up with all of the pointers in your code.
If you have a pflag.FlagSet with a flag called 'flagname' of type int you
can use GetInt() to get the int value. But notice that 'flagname' must exist
and it must be an int. GetString("flagname") will fail.
``` go
i, err := flagset.GetInt("flagname")
```
After parsing, the arguments after the flag are available as the
slice flag.Args() or individually as flag.Arg(i).
The arguments are indexed from 0 through flag.NArg()-1.
The pflag package also defines some new functions that are not in flag,
that give one-letter shorthands for flags. You can use these by appending
'P' to the name of any function that defines a flag.
``` go
var ip = flag.IntP("flagname", "f", 1234, "help message")
var flagvar bool
func init() {
flag.BoolVarP(&flagvar, "boolname", "b", true, "help message")
}
flag.VarP(&flagVal, "varname", "v", "help message")
```
Shorthand letters can be used with single dashes on the command line.
Boolean shorthand flags can be combined with other shorthand flags.
The default set of command-line flags is controlled by
top-level functions. The FlagSet type allows one to define
independent sets of flags, such as to implement subcommands
in a command-line interface. The methods of FlagSet are
analogous to the top-level functions for the command-line
flag set.
## Setting no option default values for flags
After you create a flag it is possible to set the pflag.NoOptDefVal for
the given flag. Doing this changes the meaning of the flag slightly. If
a flag has a NoOptDefVal and the flag is set on the command line without
an option the flag will be set to the NoOptDefVal. For example given:
``` go
var ip = flag.IntP("flagname", "f", 1234, "help message")
flag.Lookup("flagname").NoOptDefVal = "4321"
```
Would result in something like
| Parsed Arguments | Resulting Value |
| ------------- | ------------- |
| --flagname=1357 | ip=1357 |
| --flagname | ip=4321 |
| [nothing] | ip=1234 |
## Command line flag syntax
```
--flag // boolean flags, or flags with no option default values
--flag x // only on flags without a default value
--flag=x
```
Unlike the flag package, a single dash before an option means something
different than a double dash. Single dashes signify a series of shorthand
letters for flags. All but the last shorthand letter must be boolean flags
or a flag with a default value
```
// boolean or flags where the 'no option default value' is set
-f
-f=true
-abc
but
-b true is INVALID
// non-boolean and flags without a 'no option default value'
-n 1234
-n=1234
-n1234
// mixed
-abcs "hello"
-absd="hello"
-abcs1234
```
Flag parsing stops after the terminator "--". Unlike the flag package,
flags can be interspersed with arguments anywhere on the command line
before this terminator.
Integer flags accept 1234, 0664, 0x1234 and may be negative.
Boolean flags (in their long form) accept 1, 0, t, f, true, false,
TRUE, FALSE, True, False.
Duration flags accept any input valid for time.ParseDuration.
## Mutating or "Normalizing" Flag names
It is possible to set a custom flag name 'normalization function.' It allows flag names to be mutated both when created in the code and when used on the command line to some 'normalized' form. The 'normalized' form is used for comparison. Two examples of using the custom normalization func follow.
**Example #1**: You want -, _, and . in flags to compare the same. aka --my-flag == --my_flag == --my.flag
``` go
func wordSepNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
from := []string{"-", "_"}
to := "."
for _, sep := range from {
name = strings.Replace(name, sep, to, -1)
}
return pflag.NormalizedName(name)
}
myFlagSet.SetNormalizeFunc(wordSepNormalizeFunc)
```
**Example #2**: You want to alias two flags. aka --old-flag-name == --new-flag-name
``` go
func aliasNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
switch name {
case "old-flag-name":
name = "new-flag-name"
break
}
return pflag.NormalizedName(name)
}
myFlagSet.SetNormalizeFunc(aliasNormalizeFunc)
```
## Deprecating a flag or its shorthand
It is possible to deprecate a flag, or just its shorthand. Deprecating a flag/shorthand hides it from help text and prints a usage message when the deprecated flag/shorthand is used.
**Example #1**: You want to deprecate a flag named "badflag" as well as inform the users what flag they should use instead.
```go
// deprecate a flag by specifying its name and a usage message
flags.MarkDeprecated("badflag", "please use --good-flag instead")
```
This hides "badflag" from help text, and prints `Flag --badflag has been deprecated, please use --good-flag instead` when "badflag" is used.
**Example #2**: You want to keep a flag name "noshorthandflag" but deprecate its shortname "n".
```go
// deprecate a flag shorthand by specifying its flag name and a usage message
flags.MarkShorthandDeprecated("noshorthandflag", "please use --noshorthandflag only")
```
This hides the shortname "n" from help text, and prints `Flag shorthand -n has been deprecated, please use --noshorthandflag only` when the shorthand "n" is used.
Note that usage message is essential here, and it should not be empty.
## Hidden flags
It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text.
**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available.
```go
// hide a flag by specifying its name
flags.MarkHidden("secretFlag")
```
## Disable sorting of flags
`pflag` allows you to disable sorting of flags for help and usage message.
**Example**:
```go
flags.BoolP("verbose", "v", false, "verbose output")
flags.String("coolflag", "yeaah", "it's really cool flag")
flags.Int("usefulflag", 777, "sometimes it's very useful")
flags.SortFlags = false
flags.PrintDefaults()
```
**Output**:
```
-v, --verbose verbose output
--coolflag string it's really cool flag (default "yeaah")
--usefulflag int sometimes it's very useful (default 777)
```
## Supporting Go flags when using pflag
In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
to support flags defined by third-party dependencies (e.g. `golang/glog`).
**Example**: You want to add the Go flags to the `CommandLine` flagset
```go
import (
goflag "flag"
flag "github.com/spf13/pflag"
)
var ip *int = flag.Int("flagname", 1234, "help message for flagname")
func main() {
flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
flag.Parse()
}
```
## More info
You can see the full reference documentation of the pflag package
[at godoc.org][3], or through go's standard documentation system by
running `godoc -http=:6060` and browsing to
[http://localhost:6060/pkg/github.com/spf13/pflag][2] after
installation.

/*
Package pflag is a drop-in replacement for Go's flag package, implementing
POSIX/GNU-style --flags.
pflag is compatible with the GNU extensions to the POSIX recommendations
for command-line options. See
http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
Usage:
pflag is a drop-in replacement of Go's native flag package. If you import
pflag under the name "flag" then all code should continue to function
with no changes.
import flag "github.com/spf13/pflag"
There is one exception to this: if you directly instantiate the Flag struct
there is one more field "Shorthand" that you will need to set.
Most code never instantiates this struct directly, and instead uses
functions such as String(), BoolVar(), and Var(), and is therefore
unaffected.
Define flags using flag.String(), Bool(), Int(), etc.
This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
var ip = flag.Int("flagname", 1234, "help message for flagname")
If you like, you can bind the flag to a variable using the Var() functions.
var flagvar int
func init() {
flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
}
Or you can create custom flags that satisfy the Value interface (with
pointer receivers) and couple them to flag parsing by
flag.Var(&flagVal, "name", "help message for flagname")
For such flags, the default value is just the initial value of the variable.
After all flags are defined, call
flag.Parse()
to parse the command line into the defined flags.
Flags may then be used directly. If you're using the flags themselves,
they are all pointers; if you bind to variables, they're values.
fmt.Println("ip has value ", *ip)
fmt.Println("flagvar has value ", flagvar)
After parsing, the arguments after the flag are available as the
slice flag.Args() or individually as flag.Arg(i).
The arguments are indexed from 0 through flag.NArg()-1.
The pflag package also defines some new functions that are not in flag,
that give one-letter shorthands for flags. You can use these by appending
'P' to the name of any function that defines a flag.
var ip = flag.IntP("flagname", "f", 1234, "help message")
var flagvar bool
func init() {
flag.BoolVarP(&flagvar, "boolname", "b", true, "help message")
}
flag.VarP(&flagval, "varname", "v", "help message")
Shorthand letters can be used with single dashes on the command line.
Boolean shorthand flags can be combined with other shorthand flags.
Command line flag syntax:
--flag // boolean flags only
--flag=x
Unlike the flag package, a single dash before an option means something
different than a double dash. Single dashes signify a series of shorthand
letters for flags. All but the last shorthand letter must be boolean flags.
// boolean flags
-f
-abc
// non-boolean flags
-n 1234
-Ifile
// mixed
-abcs "hello"
-abcn1234
Flag parsing stops after the terminator "--". Unlike the flag package,
flags can be interspersed with arguments anywhere on the command line
before this terminator.
Integer flags accept 1234, 0664, 0x1234 and may be negative.
Boolean flags (in their long form) accept 1, 0, t, f, true, false,
TRUE, FALSE, True, False.
Duration flags accept any input valid for time.ParseDuration.
The default set of command-line flags is controlled by
top-level functions. The FlagSet type allows one to define
independent sets of flags, such as to implement subcommands
in a command-line interface. The methods of FlagSet are
analogous to the top-level functions for the command-line
flag set.

**Go configuration with fangs!**
Many Go projects are built using Viper including:
* [Hugo](http://gohugo.io)
* [EMC RexRay](http://rexray.readthedocs.org/en/stable/)
* [Imgur’s 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
```shell
go get github.com/spf13/viper
```
**Note:** Viper uses [Go Modules](https://github.com/golang/go/wiki/Modules) to manage dependencies.
## 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: %w \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.OnConfigChange(func(e fsnotify.Event) {
fmt.Println("Config file changed:", e.Name)
})
viper.WatchConfig()
```
### 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 more parameters. The first parameter is the key name, the
rest are the name of the environment variables to bind to this key. If more than
one are provided, they will take precedence in the specified order. 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 an 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.
Viper can access array indices by using numbers in the path. For example:
```json
{
"host": {
"address": "localhost",
"ports": [
5799,
6029
]
},
"datastore": {
"metric": {
"host": "127.0.0.1",
"port": 3099
},
"warehouse": {
"host": "198.0.0.1",
"port": 2112
}
}
}
GetInt("host.ports.1") // returns 6029
```
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"
```
### Extracting a sub-tree
When developing reusable modules, it's often useful to extract a subset of the configuration
and pass it to a module. This way the module can be instantiated more than once, with different configurations.
For example, an application might use multiple different cache stores for different purposes:
```yaml
cache:
cache1:
max-items: 100
item-size: 64
cache2:
max-items: 200
item-size: 80
```
We could pass the cache name to a module (eg. `NewCache("cache1")`),
but it would require weird concatenation for accessing config keys and would be less separated from the global config.
So instead of doing that let's pass a Viper instance to the constructor that represents a subset of the configuration:
```go
cache1Config := viper.Sub("cache.cache1")
if cache1Config == nil { // Sub returns nil if the key cannot be found
panic("cache configuration not found")
}
cache1 := NewCache(cache1Config)
```
**Note:** Always check the return value of `Sub`. It returns `nil` if a key cannot be found.
Internally, the `NewCache` function can address `max-items` and `item-size` keys directly:
```go
func NewCache(v *Viper) *Cache {
return &Cache{
MaxItems: v.GetInt("max-items"),
ItemSize: v.GetInt("item-size"),
}
}
```
The resulting code is easy to test, since it's decoupled from the main config structure,
and easier to reuse (for the same reason).
### 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.
### Decoding custom formats
A frequently requested feature for Viper is adding more value formats and decoders.
For example, parsing character (dot, comma, semicolon, etc) separated strings into slices.
This is already available in Viper using mapstructure decode hooks.
Read more about the details in [this blog post](https://sagikazarmark.hu/blog/decoding-custom-formats-with-viper/).
### 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
### 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.
### Why is it called “Cobra”?
Is there a better name for a [commander](http://en.wikipedia.org/wiki/Cobra_Commander)?
### Does Viper support case sensitive keys?
**tl;dr:** No.
Viper merges configuration from various sources, many of which are either case insensitive or uses different casing than the rest of the sources (eg. env vars).
In order to provide the best experience when using multiple sources, the decision has been made to make all keys case insensitive.
There has been several attempts to implement case sensitivity, but unfortunately it's not that trivial. We might take a stab at implementing it in [Viper v2](https://github.com/spf13/viper/issues/772), but despite the initial noise, it does not seem to be requested that much.
You can vote for case sensitivity by filling out this feedback form: https://forms.gle/R6faU74qPRPAzchZ9
### Is it safe to concurrently read and write to a viper?
No, you will need to synchronize access to the viper yourself (for example by using the `sync` package). Concurrent reads and writes can cause a panic.

# Troubleshooting
## Unmarshaling doesn't work
The most common reason for this issue is improper use of struct tags (eg. `yaml` or `json`). Viper uses [github.com/mitchellh/mapstructure](https://github.com/mitchellh/mapstructure) under the hood for unmarshaling values which uses `mapstructure` tags by default. Please refer to the library's documentation for using other struct tags.
## Cannot find package
Viper installation seems to fail a lot lately with the following (or a similar) error:
```
cannot find package "github.com/hashicorp/hcl/tree/hcl1" in any of:
/usr/local/Cellar/go/1.15.7_1/libexec/src/github.com/hashicorp/hcl/tree/hcl1 (from $GOROOT)
/Users/user/go/src/github.com/hashicorp/hcl/tree/hcl1 (from $GOPATH)
```
As the error message suggests, Go tries to look up dependencies in `GOPATH` mode (as it's commonly called) from the `GOPATH`.
Viper opted to use [Go Modules](https://github.com/golang/go/wiki/Modules) to manage its dependencies. While in many cases the two methods are interchangeable, once a dependency releases new (major) versions, `GOPATH` mode is no longer able to decide which version to use, so it'll either use one that's already present or pick a version (usually the `master` branch).
The solution is easy: switch to using Go Modules.
Please refer to the [wiki](https://github.com/golang/go/wiki/Modules) on how to do that.

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 a 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 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
* Wrapper for go 1.16 filesystem abstraction `io/fs.FS`
# 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 your own file system.
* Wrapper 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
Chown(name string, uid, gid int) : 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.
### GCSFs
Afero has experimental support for Google Cloud Storage (GCS). You can either set the
`GOOGLE_APPLICATION_CREDENTIALS_JSON` env variable to your JSON credentials or use `opts` in
`NewGcsFS` to configure access to your GCS bucket.
Some known limitations of the existing implementation:
* No Chmod support - The GCS ACL could probably be mapped to *nix style permissions but that would add another level of complexity and is ignored in this version.
* No Chtimes support - Could be simulated with attributes (gcs a/m-times are set implicitly) but that's is left for another version.
* Not thread safe - Also assumes all file operations are done through the same instance of the GcsFs. File operations between different GcsFs instances are not guaranteed to be consistent.
## 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
* 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.

(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:

documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf

Easy and safe casting from one type to another in Go
Don’t 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 doesn’t 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
you’ll 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
