# Std
{% hint style="info" %}
You can easily import all the functions from the `std` registry by including the following import statement in your code
```go
import "github.com/go-sprout/sprout/registry/std"
```
{% endhint %}
### hello
The function returns a simple greeting string, "Hello!" It serves as a basic test function to verify that the system is working correctly.
Name
Value
Signature
Hello() string
{% tabs %}
{% tab title="Template Example" %}
```go
{{ hello }} // Output: Hello!
```
{% endtab %}
{% endtabs %}
### default
The function returns the first non-empty value from a provided list of arguments. If the list is empty or the first value is empty, it returns a specified default value. If you're looking to find the first non-empty value from a list of multiple options, the [`Coalesce` ](#coalesce)function is a better choice.
Name
Value
Signature
Default(defaultValue any, given ...any) any
{% tabs %}
{% tab title="Template Example" %}
```go
{{ .Nil | default "default" }} // Output: default
{{ "" | default "default" }} // Output: default
{{ "first" | default "default" }} // Output: first
{{ "first" | default "default" "second" }} // Output: second
```
{% endtab %}
{% endtabs %}
### empty
The function checks if the provided value is empty, returning `true` if it is considered empty based on its type. This function is useful for determining whether a value is present or absent across different data types.
Name
Value
Signature
Empty(given any) bool
{% tabs %}
{% tab title="Template Example" %}
```go
{{ .Nil | empty }} // Output: true
{{ "" | empty }} // Output: true
{{ 0 | empty }} // Output: true
{{ false | empty }} // Output: true
{{ .Struct | empty }} // Output: false
```
{% endtab %}
{% endtabs %}
### all
The function checks if all values in the provided variadic slice are non-empty. It returns `true` only if every value is considered non-empty according to the criteria used by the [`Empty` ](#empty)method.
Name
Value
Signature
All(values ...any) bool
{% tabs %}
{% tab title="Template Example" %}
```go
{{ all 1 "hello" true }} // Output: true
{{ all 1 "" true }} // Output: false
```
{% endtab %}
{% endtabs %}
### any
The function checks if any of the provided values are non-empty. It returns `true` if at least one value is considered non-empty.
Name
Value
Signature
Any(values ...any) bool
{% tabs %}
{% tab title="Template Example" %}
```go
{{ any "" 0 false }} // Output: false
{{ any "" 0 "text" }} // Output: true
```
{% endtab %}
{% endtabs %}
### coalesce
The function returns the first non-empty value from the provided list. If all values are empty, it returns `nil`.
Name
Value
Signature
Coalesce(values ...any) any
{% tabs %}
{% tab title="Template Example" %}
```go
{{ coalesce nil "" "first" "second" }} // Output: first
```
{% endtab %}
{% endtabs %}
### ternary
The function mimics the ternary conditional operator found in many programming languages. It returns `trueValue` if the `condition` is true; otherwise, it returns `falseValue`.
Name
Value
Signature
Ternary(trueValue any, falseValue any, condition bool) any
{% tabs %}
{% tab title="Template Example" %}
```go
{{ true | ternary "yes" "no" }} // Output: yes
{{ false | ternary "yes" "no" }} // Output: no
```
{% endtab %}
{% endtabs %}
### cat
The function concatenates a series of values into a single string, converting each value to its string representation and separating them with spaces. Nil values are skipped, and no trailing spaces are added.
