* `GetBool(key string) : bool`
* `GetFloat64(key string) : float64`

* `GetDuration(key string) : time.Duration`
* `IsSet(key string) : bool`
* `AllSettings() : map[string]any`

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.
The zero value will also be returned if the value is set, but fails to parse
as the requested type.

### Extracting a sub-tree
### Extract 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.
Extract sub-tree from Viper.
For example, an application might use multiple different cache stores for different purposes:
For example, `viper` represents:
```yaml
cache:
```json
app:
cache1:
max-items: 100
item-size: 64
@ -687,36 +601,35 @@ cache:
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:
After executing:
```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)
subv := viper.Sub("app.cache1")
```
**Note:** Always check the return value of `Sub`. It returns `nil` if a key cannot be found.
`subv` represents:
Internally, the `NewCache` function can address `max-items` and `item-size` keys directly:
```json
max-items: 100
item-size: 64
```
Suppose we have:
```go
func NewCache(v *Viper) *Cache {
return &Cache{
MaxItems: v.GetInt("max-items"),
ItemSize: v.GetInt("item-size"),
}
}
func NewCache(cfg *Viper) *Cache {...}
```
The resulting code is easy to test, since it's decoupled from the main config structure,
and easier to reuse (for the same reason).
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)

For example, parsing character (dot, comma, semicolon, etc) separated strings into slices.
This is already available in Viper using mapstructure decode hooks.

## Viper or Vipers?
Viper comes with a global instance (singleton) out of the box.
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.
Although it makes setting up configuration easy,
using it is generally discouraged as it makes testing harder and can lead to unexpected behavior.
The best practice is to initialize a Viper instance and pass that around when necessary.
The global instance _MAY_ be deprecated in the future.
See [#1855](https://github.com/spf13/viper/issues/1855) for more details.
In all of the examples above, they demonstrate using viper in its singleton
style approach.
### Working with multiple vipers
@ -868,63 +713,22 @@ 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”?
Q: Why not INI files?
A: Ini files are pretty awful. Theres no standard format, and they are hard to
validate. Viper is designed to work with JSON, TOML or YAML files. If someone
really wants to add this feature, Id be happy to merge it. Its easy to specify
which formats your application will permit.
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.
### Why is it called “Cobra”?
Q: 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
See [TROUBLESHOOTING.md](TROUBLESHOOTING.md).
## Development
**For an optimal developer experience, it is recommended to install [Nix](https://nixos.org/download.html) and [direnv](https://direnv.net/docs/installation.html).**
_Alternatively, install [Go](https://go.dev/dl/) on your computer then run `make deps` to install the rest of the dependencies._
Run the test suite:
```shell
make test
```
Run linters:
```shell
make lint # pass -j option to run them in parallel
```
Some linter violations can automatically be fixed:

# 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://go.dev/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://go.dev/wiki/Modules) on how to do that.
**tl;dr* `export GO111MODULE=on`
## Unquoted 'y' and 'n' characters get replaced with _true_ and _false_ when reading a YAML file
This is a YAML 1.1 feature according to [go-yaml/yaml#740](https://github.com/go-yaml/yaml/issues/740).
Potential solutions are:
1. Quoting values resolved as boolean
1. Upgrading to YAML v3 (for the time being this is possible by passing the `viper_yaml3` tag to your build)
