Functions

func Export

func Export(i interface{}) (string, error)

Export exports input value to a GO code.

Example (EmptySlice)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	var v interface{} = make([]interface{}, 0)
	s, _ := exporter.Export(v)
	fmt.Println(s)
}

Output:

make([]interface{}, 0)

Example (EmptySlice2)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	var v []interface{} = nil
	s, _ := exporter.Export(v)
	fmt.Println(s)
}

Output:

make([]interface{}, 0)

Example (Err)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	_, err := exporter.Export(struct{}{})
	fmt.Println(err)
}

Output:

type `struct {}` is not supported

Example (Int)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	s, _ := exporter.Export(5)
	fmt.Println(s)
}

Output:

int(5)

Example (Pi)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	s, _ := exporter.Export(float32(3.1416))
	fmt.Println(s)
}

Output:

float32(3.1416)

Example (Slice)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	s, _ := exporter.Export([]uint{1, 2, 3})
	fmt.Println(s)
}

Output:

[]uint{uint(1), uint(2), uint(3)}

Example (Slice2)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	s, _ := exporter.Export([]interface{}{int32(1), int64(2), float32(3.14), "hello world"})
	fmt.Println(s)
}

Output:

[]interface{}{int32(1), int64(2), float32(3.14), "hello world"}

Example (String)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	s, _ := exporter.Export("hello world")
	fmt.Println(s)
}

Output:

"hello world"

func MustExport

func MustExport(i interface{}) string

MustExport exports input value to a GO code.

func MustToString

func MustToString(i interface{}) string

MustToString casts input value to a string. See ToString.

func ToString

func ToString(i interface{}) (string, error)

ToString casts input value to a string. This function supports booleans, strings, numeric values and nil-values:

• any numeric input returns string that represents its value without a type
• any boolean input returns accordingly a string "true" or "false"
• any string input results in the output that equals the input
• any nil input returns a "nil" string.

Example (Bool)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	s, _ := exporter.ToString(false)
	fmt.Println(s)
}

Output:

false

Example (Nil)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	s, _ := exporter.ToString(nil)
	fmt.Println(s)
}

Output:

nil

Example (NotSupported)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	_, err := exporter.ToString(struct{}{})
	fmt.Println(err)
}

Output:

type `struct {}` is not supported

Example (Pi)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	s, _ := exporter.ToString(float32(3.1416))
	fmt.Println(s)
}

Output:

3.1416

Example (String)

package main

import (
	"fmt"

	"github.com/gomponents/gontainer-helpers/exporter"
)

func main() {
	s, _ := exporter.ToString("hello world")
	fmt.Println(s)
}

Output:

hello world
